Title: Plated electrical contacts
Inventor: STERLING HENLEY FRANK
IPC: H01H11/04
Filed: 1982-11-05
Abstract: In an electrical contact (eg a contact blade for a connector or a relay contact), the contact making portion is a precious metal (eg gold) deposited on the surface of an amorphous metal. The contact can be made by plating a contact blade fabricated from metallic glass (eg of 40% Ni, 40% Fe, 20%B or of 92% Ni, 8% Si) with gold or alternatively the contact area of a phosphor bronze connector blade may be melted by a laser and fast-refrozen to provide an amorphous area to receive the gold plate. Because the surface of the amorphous metal is very smooth, the thickness of precious metal needed is less than that needed with conventional contacts. The nickel underlayer usually used with gold plated contacts is no longer necessary.

Title: Determining the focal length of a projection lens in a copier
Inventor: TAKAHASHI TOSHIKATSU
IPC: G03G15/04
Filed: 1982-11-23
Abstract: In a copier which is capable of copying at a continuously variable magnification, light from a source 1 passes through a microfilm to be copied which is held by a scanning system 2, and is projected by a lens 3 onto a photosensitive drum 6 by way of a movable reflection system 4 and a fixed mirror 5. In order to measure the focal length f of the lens 3, the reflection system 4 is first positioned at a predetermined location and the lens 3 is moved until an image of optimum sharpness is obtained on the drum 6: the magnification M0 of this image is then measured. Following this, the reflection system 4 is moved a measured distance b to a position 4' to alter the optical path length between the microfilm and the drum 6 by  DELTA I. The lens 3 is then moved to obtain a new image of optimum sharpness on the drum 6, whereupon the magnification M' of the new image is measured. The focal length f is then calculated by means of the formula:  f =  DELTA I/(1/M0 - 1/M' + M0 - M'). <IMAGE>

Title: Adaptive antenna arrays
Inventor: HARGRAVE PHILIP JOHN
IPC: H01Q3/26
Filed: 1983-06-11
Abstract: In an adaptive antenna array system the outputs of the array elements (10 1 .....10 n ) are weighted in a  beam forming network (11) under the control of a gradient descent weight processor (12) before being summed to provide the array output. To provide an error signal for the processor (12) the array output is fed to a limiter and the bandpass filter (20) and to a modulus detector (40). The output of the modulus detector is filtered (41) and used to control the gain of an amplifier (42) whereby the limiter output is amplitude scaled in proportion with the modulus of the array output. The amplifier output is subtracted from the array output to form an error signal feedback to the processor.
