Repositioning bases
|,
Pllt¢l Repositioning bases Installation, removal and replacement of components with sub-arc-second repeatability are possible with the kinematic bases from Newport. Each base also incorporates a patented rotating radial slot to allow mounting anywhere with any orientation on any table with 1 inch or 25 mm hole centres. Each base has a top mounting plate with an array of threaded holes which kinematically clamps to the bottom universal mounting plate with relocation repeatability better than one micrometre. Also available from the company
are precision vertical stages, which use two pairs of cross roller bearings (instead of conventional ball slides) and a precision-machined wedge block for vertical stages. The bearings run on hardened and ground steel ways to guide the wedge motion, resulting in high platform stability and parallelism ( < 0 . 5 arc-min mm -1 of travel), with vertical tracking accuracy (runout) better than 1 pm mm -1 of travel. Available in 6 mm and 13 mm travel versions, they are compatible with manual, motorized, or computercontrolled actuators.

Long travel translation stage The class TCB200 long travel range translation stages have been added to the Klinger Scientific line of precision micropositioning components. The stages have travel ranges from 200 mm to 1 m with load carrying capacities to 200 kg. The units utilize a precision stepping motor and ball screw drive system and provide accuracies to the submicron realm. Optional accessories for the tables include a linear absolute encoder with an accuracy to 1 #m or an optical incremental encoder with an accuracy to 10/~m. The stages are suitable for applications requiring high speed and long travel under a large load. The units can be assembled to provide XY positioning and can be used vertically as well. They have a recirculating bearing system to ensure trajectory accuracy. Klinger Scientific Corp, 110-20 Jamacia Ave, Richmond Hill, New York 11418, USA
PROPOSITION precious metals, bimetals and precision parts for the electrical and electronic industry Our client is an established German manufacturer, with substantial market position in England. He is planning to expand his activities in the United Kingdom. The range includes all forms of precious metals, bimetals (strip, profile, wire, tube, contact and thermo bimetal) and precision parts, e. g. plug, connector, switch, relay contact parts and is sold primarily to the following electrical industries: • low-voltage switchgear, switches and appliances • communication and data processing • automotive We are looking for a dynamic, independent cooperation resp. distribution partner, as well as a qualified individual (salesman/agent) to handle our clients interests on the British market. If such a collaboration would be of interest to you, please, apply to our consultants: KAPPELER& PARTNER International Marketing Consultants Tulpenweg 10, D-8019 Assling b. MCinchen
