Patent GB-2086789-A (GB)
Title: Threading a wire electrode in an electroerosion machine
IPC: B23H7/10
Filed: 1981-11-09
Abstract: An improved method of and apparatus for automatically threading a continuous electrode wire through a workpiece in a traveling-wire electroerosion machine wherein a rotary guide block having a tapered opening is disposed to locate the latter coaxially with a straight throughgoing hole preformed in the workpiece and arranged in alignment with a straight line path defined between a pair of wire guide members. A free end of the electrode wire extending from a wire supply or takeup is located behind the opening in the rotary guide block which is tapered convergently towards the workpiece. The electrode wire is advanced along the straight line path to introduce its free end into the tapered opening of the guide block which is rotated about its rotary axis to allow the free end to smoothly pass through the opening and then into and through the straight through-hole in the workpiece. A sensing/control circuit may be provided and arranged to detect a contact of the free end with the tapered wall of the opening to initiate the rotation of the rotary guide block or to control its rate of rotation and/or the rate of advance of the electrode wire in accordance with the particular position of a point of contact of the free end with the tapered wall.

Title: Improvements relating to shearer-loaders
IPC: E21C27/02
Filed: 1981-11-10
Abstract: The support arm 21 of the shearer-loader has, between the frame 3 and the drum 11, a projecting part 26 which extends to a position in front of the goaf side drum end face 27, the height of the part 26 being less than the diameter of the drum 11. A journal 28, extending over most of the axial length of the drum 11, is rigidly secured to the part 26 and carries the rotating drum 11. Also mounted on the support arm 21, on the outside near the mineral face, is an output gear 37 connected to drive gearing and meshing with a tooth system 46 disposed on the drum periphery. The shearer drums can have a diameter which is only slightly greater than the height of the frame, and can discharge debris readily into the face conveyor past the projecting arm 26 of small dimensions. <IMAGE>

Title: A photoconductive detector
IPC: H01L31/0224
Filed: 1982-03-12
Abstract: The output bias contact (107) or the material adjacent thereto, of a photoconductive detector (101), is shaped to concentrate an electric field bias in the immediate vicinity of the contact (107). This concentrated field sweeps away minority carriers which otherwise accumulate near the output contact and hence improves both frequency response and spatial resolution. The contact (107) may be shaped by extending it towards input bias contact (105), or the detector material (103) near this contact (107) may be configured by slotting or tapering, or an annular ring input bias contact may surround a circular disc output contact. The detectors may be used in imaging applications. <IMAGE>

Patent GB-2114093-A (GB)
Title: Cartridge-type tape cassettes
Inventor: SHIMIZU TOKUZO
IPC: G11B23/04
Filed: 1982-04-19
Abstract: The invention relates to cassettes having two spaced and rotatable reel hubs (2) with the tape (6) guided by rollers (4) from one reel hub to the other via a tape head (5). Due to various causes, including static and air build-up at the wind-on point the tape is liable to irregular wind-up onto the reel-hubs, which can lead to squeal or stretching of the tape. To eliminate, or at least substantially reduce the possibility of irregular wind-up, the cassette is characterised by guide rollers (7) the surface of each of which has flat faces (8) which are slanted at an angle with respect to the roller axis. In use the tape is made to flutter as it is wound onto a reel hub by a fluctuating motion imparted to it by the guide surface of the appropriate guide roller. Preferably two, diagonally opposite slanted faces (8) are provided, and flanges (9) are provided at the roller ends so that, in section, each roller is generally Z-shaped. <IMAGE>

Patent GB-2170314-A (GB)
Title: Measurement of depth or relief
Inventor: ZOLLMAN PETER MARTIN
IPC: G01B11/24
Filed: 1984-10-22
Abstract: Apparatus for scanning or mapping a surface 45 of varying depth or contour comprises an optical 'read' head which includes optical beam-splitting and polarising elements 20, 22, 27 as well as a thin, flexible mirror 30 which is vibrated at a high frequency by an acoustic output, e.g. that of a loudspeaker. A beam of light, e.g. from a laser 12, is focussed via the mirror so as to produce a spot image on the surface at one position thereof. A photodetector unit 55 senses the light reflected from the target. The intensity of the light reflected varies as the light spot moves into and out of focus as a function of the vibration of the mirror and the variation in the depth of the surface. The time difference between successive maxima of the photodetector output signal is then determined. In one application, the surface is moved helically relatively to the 'reading' head and the output of the photodetector unit is used to modulate the output of a 'writing' head, such as a powerful laser used to engrave a polymeric material, e.g. a flexographic printing roller. <IMAGE>

Title: Digital wireless telephone system
Inventor: PANETH ERIC
IPC: H04L65/00
Filed: 1985-10-16
Abstract: A master station communicates with the main network, whilst a set of mobile or fixed sub stations of voice or data users share the channel using time division multiplexing. The number of time division channels available depends on the quality of the transmission links, power and modulation index. The rate of errors is detected to maintain a specified condition of operation. When all available channels are occupied a busy signal is transmitted by the master station. The effect of multiplexing on the sub-links gives apparent simultaneous bidirectional transmission.
