Title: Apparatus for checking of the pairing of wires
IPC: G01R31/04
Filed: 1976-03-31
Abstract: 1502043 Testing insulated conductors COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL SA 31 March 1976 [16 April 1975] 12931/76 Heading G1U In detecting incorrect pairing of twisted pairs in a multi-wire telecommunications cable, a signal is injected into successive ones of the first wires of the pairs, and signals from the second wires of the pairs due to induction are detected. The cable has pairs ai, a<SP>x</SP>i;...an, a<SP>x</SP>n at one end and pairs bl, b<SP>x</SP>l;... bn, b<SP>x</SP>n at the other. These are connected to male multi-way connectors, which fit female connectors on the apparatus front-panel, Fig.2 (not shown). This connects ai ... an ie the first wires of the n pairs to the outputs of a demulti-plexer DM, and the corresponding second wires at the other cable end b<SP>x</SP>1... h<SP>x</SP>n to detector D1... Dn. A 10Hz oscillator 01 feeds a counter CT whose outputs provide the address inputs to the demultiplexer DM, which thus sequentially directs 2MHz signals from oscillator 02 to successive first wires ai ... an. The counter CT outputs are also de-coded D.C. to illuminate one of lamps L1-Ln on the front panel via outputs Sl-Sn, corresponding to the energized wire. Whichever second wire is twisted with the energized first wire provides an induced voltage to one of the detectors D1-Dn. That detector provides an output S<SP>x</SP>1 ... S<SP>x</SP>n to illuminate a second lamp on the front panel. These lamps are arranged, such that correctly paired wires illuminate lamps side-by-side, Figs.2, 3B, 4B, 5B, 5C (not shown). A comparator CP compares the de-coder D.C. output and the detector outputs and if these do not correspond to correctly paired wires, a low output to NOR-gate PN causes that gate to block oscillator 01, thus stopping further stepping, and the front-panel lamps stay illuminated to indicate a fault. The stepping is recommenced by operation of a push-button BD which actuates a monostable BM to give a high output, thus removing the blocking signal Ebto the oscillator.
Patent GB-556705-A (GB)
Title: Improvements in and relating to x-ray apparatus
IPC: H05G1/54
Filed: 1942-09-14
Abstract: 556,705. R÷ntgen-ray apparatus. GENERAL ELECTRIC CO., Ltd., and CALDWELL, J. T. Sept. 14, 1942, No. 12947. [Class 98 (i)] In radiographic apparatus in which the X-ray screen-image and a card identifying it are photographed, and which includes a light source for illuminating the card and a delay timing device in the X-ray exposure-initiating circuit (to allow the tube and rectifying valves to come into full operation), the exposure-initiating circuit renders the card-illuminating light source operative only during the delay period, and the circuit energizing the light-source controls a relay in the exposure-initiating circuit to prevent an exposure being made unless the light-source has been operative during the preceding delay period. In the arrangement shown, closure of the starting switch K8 energizes the clutch winding W5 of a delay timing device T1, so that after a predetermined interval normally closed contacts K9 are opened, and normally open contacts K10 are closed by a constantly-running synchronous motor Y1. The winding W1 of a transformer which lights the identification-card illuminating lamp P1 is also energized causing operation of the lamp and of a relay W3 in its circuit, which closes contacts K1 bridging the contacts K7 of a relay W4, which is thus energized and closes the contacts K7. When the delay timing device T1 opens the contacts K9 the transformer winding Wl is de-energized, extinguishing the lamp P1 and allowing the contacts K1 of the relay W3 to open. Simultaneously the contacts K10 are closed and energize a magnet winding W7 which closes contacts K12 to energize the X-ray tube. At the same time the clutch winding W6 of an exposure-timer T2 is energized, the motor Y2 of which then after the pre-set time opens contacts K11 to de-energize the winding W7 and so terminate the exposure. The opening of the contacts K11 also de-energizes the relay W4, so that the contacts K7 open and de-energize the clutch winding W6, causing the contacts K11 to open, whilst opening of the switch K8 deenergizes the clutch winding W5, restoring the switches K9, K10 to their normal positions. Contacts K3, which are open unless an identification card has been correctly inserted, and other contacts K4, 5, 6 which are associated with essential accessory apparatus, are arranged in the circuit of the lamp P1 and relay winding W3 to prevent an exposure being made unless the apparatus is correctly prepared. During the delay period the relay W3 closes contacts K2 which allow a resetting current derived from a resistance R1 and rectifier XI to pass to a millampere-seconds meter M1.

Title: Improvements in or relating to circuits for levelling datum signals interspersed in electric signals, for example television signals
Inventor: CLAYDEN RONALD THOMAS
IPC: H04N5/18
Filed: 1950-04-01
Abstract: 729,621. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd. April 2, 1951 [April 1, 1950], No. 12990/53. Divided out of 729,541. Class 40 (3). A circuit for levelling datum signals interspersed with other signals for example, television signals, comprises means for clamping said signals at a reference potential at relatively frequent intervals, means for observing the level of other datum signals at less frequent intervals and for storing a signal representing said level and means for adjusting said reference potential in response to variations in said stored level. The invention is described as applied to signals derived from the film scanner described in Specification 729,541. The signals, Fig. 2, contain datum portions 4 corresponding to blacker-than-black derived when the scanning light spot is extinguished at the end of each line, and other datum portion 5 corresponding to true black derived by scanning the bar separating adjacent film frames. The signals are applied through a condenser 1 to the input of a gamma correction circuit 2 of the type described in Specification 702,325, [Group XL (c)], and are clamped to a reference potential by means of circuit 10 of the type described in Specification 449,242 which is rendered operative once in every line by pulses 11 timed to coincide with the intervals 4. At the output of circuit 2, a bi-directionally conductive switch 6 is brought into operation once per frame during the intervals. 5 by pulses 8 and allows a condenser 7 to acquire a potential representative of the level of the other datum portion. This potential is then applied through D.C. amplifier 9 to adjust the reference potential in circuit 10. A limiter circuit 12 or 13 may be included to limit the amplitude of signals 4 in excess of true black. The rectifier shown in Fig. 3 of Specification 702,325, [Group XL (c)], may be arranged to function for this purpose.
