Title: Connectors for coaxial air spaced lines and coaxial cables
IPC: H01R13/646
Filed: 1972-12-21
Abstract: 1430373 Coaxial connector DEFENCE SECRETARY OF STATE FOR 19 Dec 1973 [21 Dec 1972] 59145/72 Heading H2E A connector for coupling two pipes such as those forming the outer conductors of rigid semi-rigid or flexible coaxial cables has a hollow spigot 2 on which a collar 12 is axially slidable under the control of a fastening member 15. Ears 13 on the collar are held in a groove 14 in the fastening member by a ring 16. Rotary movement disengages threads 17 and 18, and further rotation when an adjacent connector is present causes threads 17 to engage threads 18a, the collar 12 to slide over the adjacent spigot 2a to locate the two connectors, and finally brings the ends of the two spigots firmly against one another. Instead of complementary screwthreads 17, 18a a complementary pin and slot (not shown) can be used to bring and hold two connectors together. A dielectric bead 3 can be used to locate a centre conductor 4, when mounted on the end of a coaxial line. A spring loaded plunger 5 can be attached to the bead 3 so that in the free condition the plunger end lies proud of the spigot end. When used with rigid coaxial lines 1 the spigot can be threaded on to the line end, with semirigid lines (Fig. 2, not shown) it can be soldered in place, and with flexible coaxial cables (Fig. 3 not shown) the outer conductor can be placed round an extension 33 resting on the cable dielectric 31, and held in place by a ring 34. The centre conductor can be connected to the bead by screwthread, Fig. 1 or by soldering (Figs. 2 and 3, not shown).

Title: Optical Memory Systems
IPC: G11C13/04
Filed: 1968-12-31
Abstract: 1,188,220. Read-only stores. INTERNATIONAL BUSINESS MACHINES CORP. 31 Dec., 1968 [15 Jan., 1968], No. 61799/68. Heading G4A. Individually-controlled light sources can each read out a respective multi-area data block on an information storage plane through a lens system to an array of detector elements, one per area of the selected block. Also, an associative memory, claimed separately, has a detector element per block and each source corresponds to correspondingly positioned areas, one from each block. In a first embodiment, energization of one of a 32 x 32 array of light-emitting GaAs diodes applies light, optionally via a diffusing plate, to read out a corresponding 4 blocks of 64 x 64 blocks of optical data on photographic film, each block being 8 Î 9 bits, via a 4 x 4 lens array, a single lens, an 8 x 8 lens array and a further single lens, to a 16 x 18 array of lightsensitive diodes, the data from an 8 x 9 subarray of which, i.e. one of the four blocks, being then selected by gating. An associative embodiment, Fig. 3, operates similarly for non-associative read-out, energization of one of light-emitting diodes 9 reading out a corresponding block of memory plane 11 to light-sensitive diodes 16, lenses 10, 13, 14 being used. For associative matching, the input tag, registered at 35, enables selected light-emitting diodes in an array 18, each enabled diode switching on and off at a different frequency. The array 18 is imaged on to each block, the transmitted light being received by light-sensitive diodes 21, using lenses 14, 13, 19, 20 and beam-splitters 15, 12. One lightsensitive diode 21 corresponds to each memory block. The diode 21 outputs are gated 31 in turn for frequency analysis 32 to set a register 33 for comparison 34 with the input tag to determine which blocks give a match. The diodes 9, 16 could serve the purposes of the diodes 18, 21 by using selective bias to cause each to be light-emitting or light-sensitive as required. A simpler version of Fig. 3 omits the frequency features, appropriate diodes at 18 being energized in turn for a serial-by-bit associative match. After each bit, only those diodes 21 which gave an output are tested for an output on subsequent bits. In a final non-associative embodiment, energization of one of a 2 x 2 array of lightemitting diodes supplies light through a polarizer to read out a respective 4 of 16 blocks of stored data, each block being 2 x 4 bits, via a 2 Î 2 lens array, a single lens, a 2 x 2 array of optical AND gates, a 2 x 2 lens array and a single lens, to a 2 x 4 array of photodetectors. Each optical AND gate use an electro-optic crystal and an analyser (crossed with the polarizer) to modulate the light from a respective block at a characteristic frequency. The light from the 4 selected blocks is superimposed on the photo-detectors, the outputs of which are mixed with an electrical signal of frequency depending on the desired block to feed filters (passing side-band frequencies) which provide the bits of the desired block through associated electrical detectors.

Abstract: An internal combustion engine function control system, for example a spark ignition control system, comprising first and second pulse generating means (12, 14, 16, 18, 20) driven by the engine. The first pulse generating means (12, 18, 20) produces a train of pulses at a first frequency equal to the frequency of the required function and the second pulse generating means produces a train of pulses at a second frequency which is a multiple of the first frequency. Engine parameter sensitive means (19) are provided for varying the phase of the second pulse train relative to that of the first pulse train between limits such that the combined ordinal succession of the pulses is maintained constant. The system further includes function timing means for causing triggering of an output circuit at the end of a delay following a pulse from said first pulse generating means. The delay consists of the sum of a first delay to one of the pulses produced by the second pulse generating means and a second delay, the first and second delays being determined by the frequency and phase of the first two pulse trains. The control system may also be applied to a fuel injection control system, both for determining the instant of injection and its duration. <IMAGE>
