Patent DE-3624949-A1 (DE)
Title: System for power amplification
Inventor: WALLENDA ENGELBERT
IPC: F03B17/00
Filed: 1986-07-23
Abstract: The apparatus as a whole functions as follows: The apparatus consists of a pressure-transmitter and a pressure-transducer system, each system being equipped with 2 plungers which are connected in suspension and which can be moved in counterstroke. When one of the plungers of the pressure transmitter is in its downward stroke, one of the plungers of the pressure transducer is likewise in its downward stroke via a rope connection. An air-volume displacement without pressure variation is carried out under the individual pairs of plungers via the air-equalising pipe of the pressure transmitter and via the air-equalising pipe of the pressure transducer. The plungers located in their downward stroke are increasingly loaded, with an increasing water depth, with the hydrostatic pressure of the standing water. This operation of buoyancy reduction is to be equated with the depth variation of the plungers. Because the air pressure under the plungers is maintained unchanged, the water level of the sealing water between the plungers and the displacement bodies remains invariable in its height level. The regularity of this operation is assured. A gradient in the system can be incorporated by means of a time-offset cycle of movement of the pressure transmitter and of the pressure transducer. An air pressure equalising an opposing water column to a proportionate height is obtainable separately only via each of the plungers of the pressure transmitter. During the downward stroke of the plungers, the air-pressure cushion is ..., only in the pressure transducer, in its ... Original abstract incomplete.

Title: Light pen
Inventor: PETERSEN HANS-JOACHIM
IPC: G06F3/038
Filed: 1987-05-25
Abstract: The light pen is designed in such a manner that it contains only optical components. It is connected via an optical fibre (light guide) (6) to an optoelectric or electrooptic transducer (8). Inside, the light pin has an optical switch, by means of which it can be activated as required. This switch consists of a guide sleeve (4) in which two optical fibre parts (5, 6) are mounted in such a manner that they can be moved relative to each other in the axial direction. The two optical fibre parts (5, 6) are held a certain distance from each other by a spring (9). When the scanning tip (2) of the light pen is placed on a firm base, the two optical fibre ends move towards each other and make optical contact. The fact that the electrooptic or optoelectric transducer (8) is accommodated outside the light pen makes it possible for the light pen also to be used in an environment which is strongly polluted by radiated noise. Since the light pen requires no energy supply, it is designed to be shock-hazard-protected and explosion-protected. <IMAGE>

Abstract: According to the invention, a measuring device (10) for recording angle of rotation, direction of rotation and torque of a metering shaft (spindle) (16) integrated in the measuring device (10) is proposed which has an electronic circuit. A strain gauge measuring bridge (24) is mounted on the metering shaft (16) for the purpose of measuring torque. The purpose of incremental measurement of angle of rotation and direction of rotation is served by a pulse disc (64) which is connected to the metering shaft (16) and rotates therewith, and a phase disc (66), which is fixed to the housing and [lacuna] by a two-track optronic device formed from light-emitting diodes (86) and phototransistors (88). After being mounted in their concentric alignment relative to one another and to the metering shaft (16), the pulse disc (64) and the phase disc (66) are fixed on a bearing (42) without the need for further adjustment. The circuit according to the invention is subdivided into a rotatable part (36, 38), connected to the metering shaft (16), and a stationary part (80), fixed to the housing. A calibration system is provided in the rotatable circuit part and acts as a shunt circuit relative to the strain gauge measuring bridge (24) at the input of the measuring system. The signal of said calibration system traverses all the function stages under completely identical conditions as for the actual measurement signal from the strain gauge measuring bridge (24). The rotatable circuit part is linked to the stationary circuit part by means of inductive ring transformers (44, 46, 48). <IMAGE>
