If you use cold shields or radiation shields within applications, Abssac might have a product to help increase the efficiency of the absorption or reflection rates.
Using a unique patented process a hollow electroform with internal baffles can be produced with high structural integrity and minimal weight. The electroformed process allows integral baffles to be produced that can replace the need for costly secondary assembly operations.
By allowing a infinite amount of variations to be available, not only can the size and shape of baffle be explored but also the aperture in the baffle.
The aperture can be cut to any shape and orientation so that the baffled electroform will filter the 'light' radiation passing through it, by physically blocking wavelengths of light while not blocking others.
These electroforms are often Gold plated on the exterior for reflectivity and blackened on the interior for absorption.
Another advantage of these coldshields are used to filter out the unwanted frequencies of the visible and non-visible light spectrum as light passes through the baffle.
Shaft Collars Hold Tight Face Tolerance
Shaft collars are widely used components in the power transmission industry.
Shaft collars function as mechanical stops, clamps often used on split hubs, bearing faces and as a means for locating components on a variety of equipment including motors, gearboxes, linear actuators, packaging equipment, printing presses, medical devices, and measuring instruments. Shaft collars from Ruland are single point faced to ensure a high level of face to bore perpendicularity. The result is face runout of TIR < .05 mm (.002') on standard collars with even tighter tolerance on bearing locknuts and special designs.
A precise shaft collar face to bore relationship is important for many applications.
It ensures that components are both properly positioned and not tilted on the shaft.
Collar face perpendicularity also ensures even pressure on interfaced components.
Uneven pressure can result in premature failure of components such as bearings.
When shaft collars are subject to shock loads, precise facing reduces the likelihood that the position of the collar will be shifted.
A circular groove indicates the precision face on Ruland shaft collars.
The collars should be installed so that the groove is on the side that will receive shock loads or is against components needing precise positioning or even pressure.
Ruland offers shaft collars in aluminium, black oxide carbon steel and stainless steel, as well as engineered plastic collars.
One- and two-piece clamp-style designs are available with bore sizes from 3mm to 80mm.
Clamp-style shaft collars do not mar the shaft like traditional set-screw types (DIN 705).
Clamp-style collars also have higher holding power because they wrap around the shaft when tightened thus applying compressive stress nearly uniformly on the circumference of the shaft.
Two-piece clamp-style collars have an additional advantage since they can be installed on the shaft without removing other components.
Ruland uses forged socket hardware in all its shaft collars, which allows for higher screw torque and increased holding power.
Shaft collars are part of Ruland's complete product line which also includes rigid couplings with precision honed bores and five types of zero-backlash motion control couplings: beam couplings, bellows couplings, oldham couplings, miniature disc couplings and curved jaw couplings.

Expanded range of high capacity screwjacks
WMH Transmissions has recently expanded the range of high capacity screwjacks in stock
WMH Transmissions has recently expanded the range of high capacity screwjacks stocked at its Midlands based UK Headquarters. We have done this to ensure we continue to be one of the UK's leading suppliers of Power Transmission products. With our ever-expanding international customer base we have decided the way to continue with an extremely high level of customer satisfaction, is to maintain a stock of components that very few others can match, but also to ensure that these parts are of the very highest quality available.
We stock our range of high precision German screwjacks in component form, this enables us to produce virtually any length of stroke that a customer may require, this includes either traveling screw or traveling nut.
With our in-house leadscrew manufacture, and the recent expansion of our manufacturing capacity (which has been increased to specifically develop our trapezoidal leadscrew and nut production), we are able to offer an extremely fast turn round on our ex-stock screwjacks.
We recently supplied a complete screwjack with an extended stroke as an alternative to another manufacturer who was quoting 6 weeks.
It was assembled in less than two hours, from the time the customer arrived at our doorstep, to the time he left an extremely happy man.

RCV to showcase innovative UAV engine design
RCV Engines will exhibit a prototype multi-fuel, compact and high power-to-weight ratio engine which aims to deliver key benefits for Unmanned Aerial Vehicle (UAV) applications.
Already the subject of discussions with a number of potential aerospace customers, RCV is seeking additional partners interested in developing UAV power units based on this highly promising engine technology. Based on the company's patented Rotating Cylinder Valve (RCV) engine technology, the new engine design to be unveiled at Farnborough has been developed based on the specific needs of UAV applications for reliability, performance, light-weight construction and compact packaging.
It is capable of multi-fuel operation being already well-proven on gasoline, methanol, diesel and JP8 fuels, and considered feasible for development to operate on JP10 and Jet A.
The engine is based on a 2-cylinder 'boxer' configuration of up to 60cc with higher capacities possible in radial configuration.
The high specific power achievable through RCV technology has been shown to deliver in excess of 100hp/litre across a range of gasoline applications.
Prototype testing of the UAV concept has also demonstrated highly competitive performance, fuel consumption and cold-start capabilities on JP8 fuel.
RCV engine technology is already well proven in a wide range of applications.
To date the company has sold some 10,000 engines for model aircraft applications of up to 20cc capacity and is active in the development of engines for forest and garden and motorcycle and scooter applications up to 125cc capacity.
Commenting on the exhibition of the new UAV engine design at Farnborough, RCV Engines managing director, Eric Hill said: 'We are pleased to be able to display our new UAV engine concept at Farnborough'.
'This UAV power unit draws upon the unique benefits of performance, economy and multi-fuel tolerance of RCV technology'.
'We are already working with a number of aerospace partners but remain enthusiastic to seek out new opportunities for this highly promising engine technology'

Custom gears keep compressor going offshore
David Brown showed that it can bring its unique brand of service to the offshore industry in a critical contract for Kerr McGee.
It manufactured a custom-designed set of high speed gears for a competitor's gearbox which drives a vital compressor, in order to meet the installation schedule during a planned shutdown of the North Sea oil rig. To prepare for the onerous task of installation, two David Brown service engineers underwent offshore safety training involving simulated helicopter crashes into the sea while manufacture went ahead.
The manufacture of the gears was completed on time enabling the project to proceed to the installation stage which involved nearly a hundred site engineers from a number of partner companies.
The rig outage, which included the gear installation, was completed on time with David Brown's Adam Penrose-Bottom being named as Man of the Shutdown in a very complimentary letter from Kerr McGee.
Both David Brown men displayed 100% commitment during severe adverse weather conditions and took ownership of the project to get it completed on time.

Teamwork accelerates gearbox replacement
Pete Jackson of Jackson Power Transmissions was delighted with Flender's fast-track supply service for larger gear units when his customer, a Midlands quarry, suffered a gearbox breakdown in May.
Jackson Power contacted Flender on a Monday evening, and within 36 hours two Flender FZG size 6 units had been built and delivered to site. Had the customer opted for straight replacements of its existing obsolete gearboxes, there would have been a three-week lead time.
The new Flender gear units had to be designed and retrofitted into place by Jackson Power engineers, but the fast build and delivery time from Flender's Bradford factory meant the quarry, which produces tar and asphalt, was back up and running with a major 160-tonne order within five days of the original phone call.
The two Flender units had ratios of 25:1 and torque capacities of 15,500Nm.
Jackson commented that he had specified Flender FZG units before and particularly liked the latest split case designs, which enabled better access for maintenance in situ.
For Flender, Distribution Manager (UK and Ireland) Paul Dudley described the order as a great example of successful teamwork between Flender and Jackson Power
