Patent GB-2081383-A (GB)
Title: Rotary compressors
IPC: F04C29/02
Filed: 1980-07-31
Abstract: A sliding vane eccentric rotor oil mist compressor has a rotor stator unit (6, 4) within a compressor casing (2). In use, oil is injected into the compression space within the stator and is subsequently removed from the compressed air in two stages. The first stage is constituted by an impingement shield (10) around the stator and the secondary stage by two coalescing elements (16) within a separate separator casing (14). Coalesced oil that accumulates within the separator casing is returned to the rotor stator unit for reuse under the action of a pressure differential produced by the compressor through an oil return passage (30, 32, 36, 44) incorporating a restricting orifice (42). The passage (44) communicates with the compression space at a point where the pressure is substantially above atmospheric and not with the compressor inlet. The oil return pressure differential is therefore smaller than normal which permits the orifice (42) to be larger than normal thus reducing its tendency to become clogged.

Patent GB-2069765-A (GB)
Title: Electromagnetic switch
IPC: H01H50/14
Filed: 1981-02-13
Abstract: An electromagnetic switch suitable for controlling glow-plugs of an internal combustion engine, has an additional single-turn coil (22) for monitoring the current flowing through the fixed contacts (19, 20) on a contact carrier (21) of the relay. The coil (22), the connection (23) and the contact carrier (21) are together stamped from a metal sheet and are subsequently bent to the desired shape. Separate connections between the ends ofthe coil (22) and the connection (23) and the contact carrier (21) are thus avoided, thereby reducing the voltage drop between the connection and the contact carrier. The coil 22 may have a single turn and carry the current for four glow-plugs. A further coil 27, having four turns, may carry the current for a fifth glow-plug; any unbalance between the magnetic fields of the coils due to a fault actuating contacts disposed in coil 27. <IMAGE>

Title: Detents and measure dispensers
IPC: G01F11/32
Filed: 1981-03-12
Abstract: A dispenser in particular for measured tots of spirits has the the slide valve controlled by a timing device which holds the valve in chamber-filling and chamber-emptying positions to avoid short measure. The timing is achieved by a magnetic ball 30 in a cylinder filled with a hydraulic fluid which cylinder is rotatable through 180 DEG  about a horizontal axis disposed transversely to the cylinder at one end of the cylinder between vertically upstanding and vertically depending positions. The ball attracts magnets acting as motion preventing detents (23). The normal slide value return spring may prevent the catches releasing merely by means of magnetic attraction unless the slide valve is first freed from that spring; therefore an auxiliary catch or the upper catch can be a settable means which is loaded by upward motion of the slide and released by a small magnetic trigger force. <IMAGE>

Title: Monitoring and controlling face equipment in coal mining
Inventor: BENTHAUS FRIEDRICH
IPC: E21D23/12
Filed: 1981-07-24
Abstract: Face equipment is controlled by a computer 5 using the spatial position of a face conveyor 2 as a reference plane. At a first cut the actual measured values and the actual state values of a winning machine 3 and the face conveyor 2 are compared with desired measured values and desired state values, and control signals are issued taking deviations into account. Corrections of the desired values are performed by the computer in stages. The hardness of the roof 13 and of the floor 12 are detected by probes 610,620 as further operational state values and serve as control parameters in such a manner that the winning machine 3 cuts into the softer adjacent rock in order to produce a sufficiently large face opening in the case of localised disturbances or seam restrictions. <IMAGE>

Title: A power supply for an electrostatic coating device
IPC: H02H7/00
Filed: 1981-08-03
Abstract: A high-voltage power supply for an electrostatic coating device is automatically switched off if an input earthing terminal 34 is not properly connected to ground via a mains-supply ground wire 24. First and second gas discharge lamps 36, 46 monitor the potentials between the input earthing terminal 34 and the input line/neutral terminals 30, 32. If terminal 34 is not earthed, the potentials will be insufficient for either lamp to conduct. Neither opto-isolator 52, 54 will therefore be able to conduct, and as a result relay 80 will not close. <IMAGE>

Title: Interferometer
IPC: G01D5/26
Filed: 1981-09-18
Abstract: Interferometers are known for measuring the displacement of an object 6 with an accuracy of a fraction of 1  mu m, having digital display, and forward/reverse motion discrimination. To avoid the use of a special frequency stabilised laser source producing oppositely polarised beams of different frequencies, an interferometer is provided having a simple laser source 1, in which an interference line pattern is formed on a detection system 20 having a moving grating-like structure whose grating period corresponds to the period of the interference pattern. The effect of a moving grating is provided by a detection system comprising a linear array of photodiodes in which sequential activation of interjacent groups of photodiodes by a ring counter moves an effective grating pattern along the array. By counting the number of periods in the output signal of the detection system, changes in the measuring arm b of the interferometer can be measured with high accuracy. The interferometer may assist in measuring and controlling the movement of an optical recording head (Figure 7). <IMAGE>

Abstract: In a digital information storage and read-out system displaying a map of terrain traversed by a vehicle, elevation information for a large area of terrain is stored on a tape cassette in compressed form. Coefficients of a discrete cosine transform (DCT) are calculated along X-lines and their differences between successive lines are recorded by differential pulse code modulation (DCPM). Compressed data from the cassette are loaded arbitrarily into intermediate memory (20) via an address directory. Data blocks are read out thence rapidly as required via a reconstruction processor (30) where the inverse DPCM and DCT transforms take place. Each block of digital elevations is loaded as required, North upward, arbitrarily into a Scene memory (35) whence it can be read-out via a Scene memory address directory, with the vehicle at the centre and vehicle heading upward. The display is assembled in a RAM 65 and read-out serially for display on a CRT (75). <IMAGE>
