Patent EP-0125045-A1 (EP)
Inventor: SMITH IAN ROBERT
IPC: G02B21/00
Filed: 1984-04-11
Abstract: The invention consists of acompact substantially frictions positioning device for guiding motion of an object accu- ely along one or two axes. The object is supported on a )ck (13), which is attached to the inner ends of two pairs of  K ible arms (14) connected to bars (15). Arms (14) form a uble support assembly which constrains block (13) to otion along a single axis, providing bars (15) are allowed to ove inwards slightly as the block (13) is displaced. This is nieved by supporting bars (15) on four springs (16) from ed blocks (17). Springs (16) exert a restoring force on bars i) as block (13) is displaced, resulting in block (13) returning its rest position when the displacing force is removed. ocks (17) may be mounted on a connecting plate which is pported on a second double hinge assembly comprising ns (19) and restoring springs (18), permitting a similar otion of block (13) along an axis at right angles to the first is. Motion is imparted to block (13) by means of elec- magnetic drive motors. The device is especially suited for e as an x-y scanner in scanned image microscopy and can used to scan the position of an acoustic lens in a combined inning acoustic and imaging optical microscope.

Abstract: A piezo-electric acoustic transducer has two strip-shaped terminal leads for connection of an acoustic-electric transducer plate to an amplifier assembly of the microphone. Previously the two leads were manually soldered to Griplet soldering rivets on the component side of the circuit boards with the addition of soldering tin, and were insulated from the housing by means of an insulating ring. In the present invention, the terminal strips are directly soldered to the connector paths of a flat amplifier assembly and are electrically insulated from the housing by means of a tab. With this type of automated soldering and insulation, a work piece carrier is provided with a plurality of devices for the mounting of the flat assembly on the carrier plate.

Abstract: A fluid amplifier (10) for sensing the level of a liquid in a reservoir, storage tank of other container and for generating a differential in pressure signal in response to the static presence of the liquid level at a predetermined level. An inlet (14) develops a liquid flow stream (16). A first passage (20) of major cross-sectional dimensions is provided for delivering a major portion (22) of the flow stream to the reservoir or storage tank. A second passage (24) of minor cross-sectional dimensions is spaced laterally of the first passage for developing a small signal fluid power stream (26) substan- , tially parallel to the major supply stream (22). A sensor (28, 30) is responsive to the static presence of the liquid level at the predetermined level for altering the smaller fluid power stream (26) from its substantially parallel flow condition to a condition in which it diverts and attaches to the major supply stream (22). A signal developing device (32, 34) is provided for receiving a fluid pressure signal of one magnitude when the signal fluid power stream (26) is parallel to the major supply stream (22) and of a second magnitude when the signal fluid power stream is diverted.
