Title: Digital control and memory arrangement particularly for a communication switching system
Inventor: WIRSING HOWARD LEROY
IPC: H04Q3/545
Filed: 1968-11-06
Abstract: 1,223,765. Automatic exchange systems. AUTOMATIC ELECTRIC LABORATORIES Inc. 6 Nov., 1968, No. 52664/68. Heading H4K. [Also in Division G4] A plurality of subsystems have access to a common memory on a multiplex system. If one subsystem has extracted data from an address in the memory, any other subsystem seeking data from that address is blocked. The invention is applied to a telephone system in which access to a destructive read-out ferrite core memory 400 of linear select type is had in interleaved manner by three subsystems (1) register decoder apparatus 110, (2) translator and route selector 120, and (3) a system comprising trunk scanner 130, peg count section 140, or maintenance console 150. Read-out and write-in is effected over the paths shown. An address generator 500 supplies appropriate timing pulses, Fig. 2, to all blocks of common control equipment. The telephone equipment is of known type with subscriber lines, trunk lines, carrier equipment, operators' positions, register-junctions and so on. The memory is sub-divided into rows allotted to each register-sender junction. In each row all information relating to the progress of a call such as seizure and release of equipment is recorded. Each word-time provides for the generation of the address of a word, followed by reading the word from the memory into the appropriate read buffer, and writing the word back into the memory. As seen from Fig. 2 three word times in respect of the three subsystems are interleaved enabling the three subsystems to be operating simultaneously. In the third subsystem the trunk scanner and maintenance console have access to the memory in alternate word times. The trunk scanner during operation of a reed relay tree allots its turn to the pig-count system for registering amount of use of pieces of equipment. Because of the interleaving it is possible that the data in a memory location addressed has been read out and not yet written back. In such a case the subsystem seeking the data has its address generator stopped until the address is available. This is achieved by parity circuits comparing addresses sought by the various subsystems.

Abstract: 1,180,953. Holography. MEDIDATA SCIENCES Inc. Nov. 20, 1967 [Dec. 6, 1966], No.52695/67. Heading G2C. Non-coherent light from an object 10, which is either illuminated by a non-coherent source or is luminous and the light therefrom is rendered quasimonochromatic by means of a narrow band filter, is divided by a prism 14, 18, into two beams 26, 28, which form a hologram at 32. As shown the semi-reflective interface 34 of the prisms divides the incoming beam into two beams each of which is doubly reflected by the roof prism portion of the prisms 14, 18, and then passed through lens 30 to photographic film 32 so that the beams 26, 28, appear to originate from two mirror images 22, 24, which are symmetrical with respect to point O<SP>1</SP> corresponding to point O on the optical axis. The prisms 14, 18, may be formed from a pair of half cubes and a pair of roof prisms cemented together. The hologram is reconstructed in the normal way and produces a pair of coplanar images (62, 64, Fig. 5 not shown) corresponding to images 22, 24.

Title: Annunciator for an electrical system including built-in self-testing equipment
IPC: G05B23/02
Filed: 1974-12-09
Abstract: 1439110 Selective signalling BENDIX CORP 9 Dec 1974 [17 Dec 1973] 53168/74 Heading G4H An annunciator is for use with a system 2 having built-in self-testing equipment for performing a test sequence including a plurality of test step groups, and which system provides first and second pulses indicative of the steps and successfully-completed steps respectively, the annunciator counting the steps, ensuring sampling prior to the completion of a test step, detecting completion of a first said group of steps, and detecting a failed step in a group other than the first. As disclosed, the system 2 is an aircraft control system, and the annunciator derives its power from system 2. System 2 provides a pulse at A at the end of each test step and an additional short "group skip" pulse at the end of each group. If any groups are omitted, an appropriate number of extra "group skip" pulses can be counted to indicate the group (counter not shown). The test steps are counted at 10, 12 (with display at 18, 20), the "group skip" pulses being eliminated by means of a one-shot 8. A flip-flop 34 is switched at the end of the first group to give a display at 54, and to enable a NAND 40 and flip-flop 42 to detect failures in the first and subsequent groups respectively in response to pulses at B from system 2. In the first group (in which the test equipment is itself tested) a 5 v. pulse at B indicates fail, whereas in subsequent groups it indicates pass. There is a pass/fail display at 56. A sample results generator 22 ensures that failure detection at 40, 42 is only effective a short time before the end of each step. Failure is displayed at 60 and (subject to manual override 52) stops the testing to permit trouble-shooting.

Abstract: 1,187,235. Telephone sub-station circuits. D. T. WAYTE. 21 Nov., 1968 [23 Nov., 1967], No. 53284/67. Heading H4K. A telephone sub-set has a non-contactmaking switch that prevents the making of outgoing calls but is such that in response to ringing current the loop can be made to answer incoming calls. The loop is normally broken by a silicon-controlled rectifier SCR which isolates the cradle switch contacts. A rectifier R detects ringing current to switch SCR on and allow the cradle switch contacts to make the loop in answering a call. An authorized person can set up outgoing calls by means of a locking mechanism which enables the cradle switch contacts to make the loop. Outgoing calls may be established by use of a coin release mechanism. A triac may be used in place of a siliconcontrolled rectifier.

Abstract: 1302070 Digital measurement SPERRY-SUN WELL SURVEYING CO 20 Nov 1970 [21 Nov 1969 (3)] 55276/70 Heading G4H  In borehole apparatus digital measurements representing for example the angular position of a housing relative to two planes 90 degrees apart and the directional orientation of the housing relative to the earth's surface are transmitted to the surface by superimposing on an A.C. signal logical signals at a predetermined phase of the A.C. signal. As described the position of the housing relative to one plane is determined by counting pulses from a pulse generator (21, Fig. 4, not shown) in a 16-stage counter (113) for the time during which an AND gate (109) is enabled. The gate is opened when a slit (56, Fig. 2, not shown) in a shield (58) passes between a lamp (48) and a first photo-cell (53) on a motor-driven disc (39). The gate is closed when the lamp passes a second photo-cell (64) on the housing. Similar apparatus is used to measure the position of the housing in the second plane. The directional orientation of the housing is similarly determined except that a gyroscope (18, Fig. 3, not shown) is used to position a slit (95). The measurements in the three counters are then read out using a ring counter 116 (Fig. 5) pulsed by a scan drive 117 which delivers an output signal at the 90 degrees phase of the A.C. power signal applied to its input. The power signal is also applied to three gates, each associated with a counter, which are sequentially enabled by the output of the last stage of counter 116 to read out serially at the 270 degree phase of the A.C. signal first the contents of the first pendulum counter followed by the contents of the second pendulum counter and gyro counter. The resulting frame of 48 data bits are superimposed by a gate line bit insert circuit 134 (Fig. 6) on to the power signal at the 270 degree phase position, sync. signals being inserted at the 90 degree phase position before and after each frame by a circuit 128. At the surface a circuit 141 (Fig. 8, not shown) removes the sine wave and processing circuit (142) transmits the data bits to a shift register (148) the contents of which are fed to a store in a computer. The sync. bits are used to reset the shift register to zero.
