摘要：The electromagnetic transponder has an oscillator (L1) generating a high frequency signal. There is a second passive oscillating circuit (L3,C3) at a distance from the first circuit. The second passive circuit forms a concentrator (20) of magnetic flux which is detected by a third transponder oscillating circuit (L2,C2).

Releasable connection of auxiliary switches - using actuation nipple set in housing

Tachogenerator, esp. brushless type, with permanently magnetised rotor - has groups of coils arranged in stator slots with small differences to maintain constant voltages or currents

Manually removable actuator handle e.g. for medical equipment - has spring-loaded plunger to allow coupling balls to move clear of engagement

Fabric section transfer - utilises pneumatic drive on needled elements to pick=up separate sections

Two-part joint for handling tool for robot - consists of two contra rotating angled segments activated by hydraulic or electric power

Electrical strand conductor attachment to plate - inserting wire ends in formed aperture followed by pressing

Multistage fluid cylinder - has fluid chamber between cylinder and primary piston, which forms closed system with secondary piston

Washing machine incorporates washing solution container - which is suspended on housing via springs, suspension points on housing comprise spring bases mounted in recesses

Safety tank with improved protection - has soft PVC tear resistant layer sprayed onto inner wall or assembled as prefabricated part during mfr.

Connecting electrohydraulic valves of system contained in fixed housing - applying wire-wrapped pins with leads brought out to edge connector points for motor vehicle brake installation

Remotely operated device for replacing chimney liners - is pneumatically operated with video camera following liner to be positioned exactly

Fixing element holding switch terminal on rail - has slide element latching into terminal for secure retention
