Patent GB-2077638-A (GB)
Title: Drill feed
IPC: B23Q5/26
Filed: 1979-10-19
Abstract: Hydraulic rams 10 have piston rods 9 connected to a quill 11 with a rotating drill 14. Oil is fed at first flow rate to extend the rams. The piston rods thus move the drill to work surface. On reaching the work surface the resistance from the work piece stops the drill and piston rods feed. As oil is still fed into the rams they extend, causing their cylinders 16 to move upwardly to close a gap 'A' between their tops and a housing flange 2. Switches 28 are actuated and divert oil through a restrictor to the rams. This causes the rams to feed the drill at a reduced rate. <IMAGE>

Title: Electric switches
IPC: H01H25/04
Filed: 1980-03-14
Abstract: A switch for use with electrically adjustable wing-mirrors, for vehicles, incorporating reversible electric motors has an operating member (27) which can be rotated about its own axis and can be tilted to and fro from a central position in each of two mutually transverse planes. First and second moving contacts (31 and 32) cooperate with fixed contacts (19 to 24) when the operating member is tilted. When the direction of tilting in each plane in each rotational position is reversed the connections between the fixed and moving contacts are reversed, there thus being four electrically distinct combinations of connections between the fixed and moving contacts, each of which is reversed on the tilting of the operating member (27) being reversed. Tilting of the operating member (27) can be effected by means of a plate, while rotation of the operating member can be separately effected by means of a slider and lever. The operating member (27) is returned to its central position by springs. <IMAGE>

Title: Process for the preparation of optically active aryloxyalkanoic acid compounds

Title: Long string racket
IPC: A63B51/00
Filed: 1980-06-27
Abstract: Tennis and racquetball rackets having a conventional grip 11, shank 12, and head 13 supporting a string network including transverse strings 24 are given significantly longer longitudinal strings 25. This is made possible by extending long strings 25 from the distal boundary 17 of frame 15 across ball-hitting region 20, through shank region 12, to a proximal end support for the strung lengths of strings 25 located in grip 11. The long strings 25 are guided or fanned across ball-hitting region 20 and are preferably passed through a suspended shank guide holding them clear of the frame. They offer substantially longer strung lengths for tensioning and deformation to give shots higher velocity and increased accuracy without increasing the overall size of the frame or racket. The longer strings are also strung at higher tensions than the transverse strings so that both long and transverse strings vibrate at about the same frequency to cooperate with each other in simultaneously returning stored impact energy to a ball being hit. <IMAGE>

Title: Improvements in or relating to viewing apparatus
IPC: H04N7/18
Filed: 1980-07-04
Abstract: For viewing a scene through a back-scattering medium such as turbid water, the scene 3 is scanned with a beam of light 4 which illuminates successive areas 2 thereof and the entire scene is viewed with a conventional television-type camera 12 displaced laterally from the light-source. The camera output signals are gated so that only signals arising during each frame in a "window" 18 of the TV raster which corresponds to the instantaneous position of the image of the illuminated area are fed out. The camera output is digitised and fed to a store 21, whence it s displayed on a visual display unit 22 with the picture-content of each window occupying the same relative position as in the original scene. The store- content relating to one window is updated each frame, and the whole store- control once per complete light-scan of the scene. <IMAGE>

Patent GB-2101773-A (GB)
Title: Improvements in and relating to heaters
Inventor: DAVIES JOHN GARFIELD
IPC: G05D23/24
Filed: 1981-06-18
Abstract: The problem of the matching of the output of a space heater RL to the rise in ambient temperature resulting from the use of the heater is dealt with by controlling the supply of energy to the heater by means of an energy regulator fitted with a manually operable control VR to preset the maximum rate at which the regulator can feed energy to the heater. The energy regulator also incorporates a temperature sensing device TH1 that monitors changes in ambient (room) temperature and adjusts the energy regulator accordingly, reducing the mean power fed to the heater by the "burst-fire" control of triac T1 as the sensed temperature rises. The circuit shown operates by comparing the voltage at pin 5 of an integrated circuit with that at pin 4. The latter voltage depends on a divider circuit preferably incorporating a second temperature sensitive device TH2 and is a threshold voltage with which the ramped voltage on pin 5 is compared. The heater may be a radiant or convector heater, or a cooker element. <IMAGE>
