Title: Method and apparatus for testing circuits
Inventor: BRACEY STANLEY
IPC: G01R31/28
Filed: 1981-06-18
Abstract: A circuit, particularly a multi-layer circuit on a printed circuit board or hybrid substrate, or any circuit conductor interconnect system is tested with a single probe. A high voltage is successively connected between each desired testing point or node of the circuit and an optically transparent electrically conductive plate positioned at a set distance from the circuit substrate, within an electron discharge gas. A succession of image or field patterns corresponding to the pattern of conductive paths on the circuit base are successively provided due to discharge between the path and plate. By comparison of these successive patterns with corresponding fiducial patterns, the presence of unwanted or absence of desired conductive paths is readily established. The apparatus can be adapted for manual, electrical or electronic scanning, and the comparison of circuits can also be adapted for visual or computer assessment. The fiducial patterns are produced by a number of means including a closed circuit television camera, a duplicate plate or a standard diagram. <IMAGE>

Title: Locks
IPC: G07C9/00
Filed: 1981-07-08
Abstract: A lock-and-key arrangement, is operated by the presentation of a key to a specific surface part of the door or surroundings. No apertures keyholes, projections or other features easily damaged by vandalism or weather are exposed at the entry. The key and lock portion cooperate in a contact-less manner, e.g. by inductive coupling, to operate the lock when a correct key is presented. The means to identify a key as correct can include making the key with internal tuned circuits to couple transmitter and receiver coils in the presentation portion only at a selected individual frequency. Specifically a lock-and-key arrangement includes a voltage controlled oscillator 24 controlled by a sawtooth waveform 22 which is also supplied 23 to a receiver gate 28 as a reference signal. The amplified oscillator output is radiated at coil 27 and when coupled by a suitable key is received at coil 41. The control wave- form is detected from the received oscillator 42, 44 and compared with the reference in gate 28. Agreement within set limits operates the lock 10. A recess in the surface can ensure correct key presentation. <IMAGE>

Title: Measuring the amount of unsteadiness in video signals derived from cine film
Inventor: STOREY RICHARD
IPC: H04N9/11
Filed: 1983-03-11
Abstract: A measure of the amount of unsteadiness in a video signal derived from cine film (caused e.g. by printing misregistration) is made by delaying (14) signal by a delay of one film frame period to make two consecutive frames available, subtracting (16), rectifying (24), and integrating (26) over one film frame period. Compensation for picture detail may be provided by measuring (52; Figure 3) the high frequency detail in the two frames, adding these values, and using the resultant as divisor in a divider (58) connected to receive the rectified difference signal. The unsteadiness signal can advantageously be used in apparatus which automatically conceals imperfections in the picture arising, e.g. from blemishes on the film. <IMAGE>

Title: Fast response gauging system
Inventor: KYRIAKIS JOHN
IPC: G01B11/10
Filed: 1984-06-01
Abstract: The width of a traveling body 2 is measured in two ways. A narrow beam is scanned across a path which includes the width of the travelling body from a source 1 to a receiver 4 whose output will be a square wave with a period of low output while the beam is scanning across the width of the body. The body 2 is also irradiated by a broad beam from a source 5 and the amount of radiation at receiver 6 gives a measure of the ratio of the width of the body 2 to the width of the broad beam. The second method is instantaneous, but is subject to zero error. <IMAGE>

Title: Electrostatographic magnetic brush development apparatus
Inventor: MASHAM ROGER DEREK
IPC: G03G15/09
Filed: 1984-06-05
Abstract: Electrostatographic development apparatus comprises two magnetic brush rolls (41, 42) both adapted to develop an electrostatic latent image on the surface of a photoreceptor drum (1). The two developer rolls (41, 42) are mounted one above the other for rotation in opposite senses (54, 55) so as to feed developer material between them towards the photoreceptor surface. A third magnetic brush roll (43) acts as a transport roll, to carry developer material into a cross-mixing arrangement (44) through which the developer material drops for mixing and recirculation. The developer material which is fed between the two developer rolls (41, 42) is split magnetically by the arrangements of stationary magnetic poles in magnets (51, 52) within the developer rolls so that the developer material is split into two streams of the desired proportions for optimum development of the electrostatic latent image. <IMAGE>

Title: Microstrip rotman lens
Inventor: MUSA LUMA SALEEM IBRAHIM
IPC: H01Q3/24
Filed: 1986-06-04
Abstract: A Rotman lens consists of two flat parallel metal plates with convexly curved ends. At one end there is a number of radio frequency launchers, e.g. waveguides, whose axes are normal to the curve. At the other end there are radio frequency pick ups, coupled in use by coaxial cable to the elements of a linear array of antenna elements. If the launchers are successively pulsed, the antenna elements emit a narrow scanning beam. To improve this arrangement as constructed in microstrip, the ends of the launchers A1-A7 are cut at angles so that they emit beams into the lens at angles to the axes of the launchers. This is stated to improve scanning characteristics. <IMAGE>
