Patent GB-2095504-A (GB)
Title: Laser rangefinders
IPC: G01S17/10
Filed: 1982-03-01
Abstract: A laser rangefinder comprises a transmitter (19) controlled by timer (16). The receiver of the rangefinder comprises an avalanche photo- diode (APD) (10) the sensitivity of which is controlled in a time-programmed manner by a bias voltage controller (11) which receives timing pulses from the timer (16). The time-programmed control operates to render the APD 10 insensitive to protect the receiver against optical element backscatter and atmospheric backscatter prior to rendering the APD(10) sensitive to monitor return pulses from remote targets. Optimum performance of the APD 10 is achieved by provision of a monitor circuit (24) which in combination with controller (11) establishes the breakdown voltage of the APD 10 at the temperature prevailing on each occasion immediately prior to firing of the laser transmitter (19) and derives therefrom the corresponding APD operating voltage to be achieved when the APD(10) next becomes sensitive for return pulse monitoring, this operating voltage being a fixed fraction of the previously established APD breakdown voltage. An arrangement for implementing circuit (24) is described (Fig. 3, not shown). <IMAGE>

Filed: 1983-01-21
Abstract: The longitudinal edge portions of an elongate retaining element 6 cooperates respectively with an elongate abutment 12 on a bolt 2 and an elongate abutment 8 on a lateral housing wall 3 in order to prevent the bolt from being forced back from its locking position. Element 6 is spring- urged and automatically takes up its holding position when the bolt is shot. The bolt is moved by the camming device 13, one arm 14 of which pushes the element 6 back into its groove 9 whilst the other 17 withdraws the bolt. Fig. 7 shows an adaptation for a latch-bolt wherein bolt 2 is spring- urged to its extended position, but element 6 only engages the bolt abutment when sensor 27 is depressed - such as by the edge of a keeper in which the bolt 2 is engaged - to align its notch 31 with the element 6. In other embodiments, not shown, the element may be of square cross- section or of a major sector of a circle, in all embodiments the element extends across the width of the bolt. Fig. 10 shows a feature which may be added to the above to prevent door forcing. <IMAGE>

Patent GB-2161103-A (GB)
Title: Electron beam hole-drilling
Inventor: HOWARD CURTIS GILMORE
IPC: B23K15/08
Filed: 1984-07-03
Abstract: When drilling very small diameter holes in workpieces 24, there is a great tendency for expulsed workpiece material to travel back along the electron beam path (20, Fig. 1) and to deposit as debris within the interior of the gun 22. The debris is caused to mostly land at a recess 54 in the rim 60 of a rotatable interior shield 44, positioned adjacent the beam path inside the gun. The deflection angle ( alpha ) of the electron beam is precisely adjusted so that the expulsed workpiece material lands in the recess, from whence it is removed by a scraper. A tab 64 is placed within the recess at the rim of the shield, and helps remove small amounts of deposit which still adhere to stationary parts of the electron beam gun system adjacent to the shield. In this embodiment, a resilient scraper such as a wire brush 66, is used to remove adhering debris from the rim of the shield. <IMAGE>

Patent GB-2164186-A (GB)
Title: Signature verification
Inventor: COOKE ROGER ERNEST
IPC: G07C9/00
Filed: 1984-09-04
Abstract: In order to permit verification of a signature at a point remote from initial registration of a standard signature and without reference to a central data bank, the process of generation of the standard signature at the point of registration is analysed and a transform of the standard signature derived therefrom. Both the signature and the transform are recorded on an item, for example a traveller's cheque or a credit card. When the traveller's cheque is presented for encashment, the signature of the person presenting it may be verified by deriving a transform of the signature as generated by the person and comparing the transforms. Whereas the signatures may appear visually identical, a fraudulent signature will not have been produced in the same manner as the original standard signature and the transforms will differ.
