Title: Improvements relating to electrical apparatus for improving and checking textile yarns
IPC: B65H63/06
Filed: 1959-04-30
Abstract: 916,019. Determining physical dimensions. SCHOLTEN & ZONEN (CURACAO) N.V., J. F. April 30, 1959 [May 1, 1958], No. 14815/59. Class 37. In apparatus for improving or checking textile yarns of the type in which an electric analogue of the yarn diameter or mass per unit length is formed and yarn parts having a diameter or mass per unit length which shows a substantial deviation from the average are caught and removed or counted by means of a relay which is energized by electrical impulses from the electric analogue of the yarn parts, the fluctuations in the electric analogue are rectified and smoothed to produce a D.C. voltage which negatively biases a circuit controlling the relay and the input voltage of the relay circuit is derived without rectification from the electric analogue. In the embodiments a capacitative detector provides the electric analogue; it is stated that an electro-pneumatic or photoelectric detector may be employed. The rectified and smoothed amplitude of the normal statistical fluctuations of the circuit input voltage represents the average yarn diameter (or mass per unit length); manual resetting of relay circuit bias is thus obviated. In the arrangement illustrated by Fig. 1 the analogue voltage is applied via capacitor C 1  to amplifier V 1  whose output is fed to thyratron V 2  via potentiometer R 3  and capacitor C 7 , and via capacitor C 3  to a rectification and smoothing circuit which includes diodes D 1 , D 2 . A constant negative bias is applied to the junction of components R 4  and C 4 . When a slub of a diameter greater than a predetermined ratio to yarn size is detected the thyratron fires and relay 5 is energized to actuate yarn-cutting knife M; the predetermined ratio is adjustable by potentiometer R 3 . In another circuit arrangement a further diode is provided to prevent relay operation when very short slubs are detected, Fig. 2 (not shown). In a further circuit arrangement a second thyratron is utilized in a network, connected to the first thyratron, to actuate a discharge lamp indicator when incorrect circuit operation ensues, Fig. 4 (not shown), due to insufficient automatic negative grid bias on the first thyratron.

Filed: 1971-05-17
Abstract: 1355665 Vehicle lighting systems SWFSPEZIALFABRIK FUR AUTOZUBEHOR GUSTAV RAU GmbH 17 May 1971 [2 June 1970] 15239/71 Heading H2H A circuit for the headlamps of a vehicle comprises a relay STR with a contact u having two stable positions, a switch DTS which ensures that when the headlamps are initially switched on their dipped lamps AbLl, AbLr are illuminated and a switch AFTS for switching the headlamps from full beam to dipped beam or vice versa. When a push button switch SL is pushed in, a positive supply voltage is connected via terminals 30, 58 of the switch DTS and the contacts of the push button to parking lights StLl, StLr. An indicator lamp KL is also illuminated. On depression of a push button switch FL, linked mechanically with the switch SL to ensure that both the switches SL, FL are closed, the positive supply voltage is fed via the contacts of the switches SL, FL and a linkage V to a terminal 56 of the relay STR. As shown, the contact u is in its "dip" position so that the dipped beam lamps AbLl, AbLr are illuminated. The closure of the switch FL momentarily closes additional contacts k of the switch DTS so that the coil of the relay STR is short circuited by the contacts u and k. The relay coil is therefore not energized thus preventing the contact u from switching to its full beam position. In the event that the contact u was in the full beam position when the switch FL was depressed, the momentary energization of the relay coil via the contacts k and the dipped headlamp filaments changes the contact u back to its dipped position. Successive operations of the switch AFTS energize the relay coil to move the contact u between its two stable positions for illuminating the dipped headlamps AbLl, AbLr or the full beam headlamps FLl, FLr. In a modification a second relay having a coil in parallel with the dipped headlamps is provided.

Title: Adaptive recognition system
IPC: G06V10/75
Filed: 1964-04-14
Abstract: 1,001,398. Automatic learning circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 14, 1964 [April 26, 1963], No. 15419/64. Heading G4R. In an adaptive recognition system of the kind designed first to learn a given sequential pattern so as subsequently to be able to recognise it, a circuit is provided able to give a prediction of the missing part of a pattern upon receipt of other portions of it. The invention is described with reference to the system of Specification 985,020, Figs. 1A, 1B. In this three 10- bit parallel-mode words are shifted into stores 1, 2, 3, the first word entering store 1, moving on to store 2 when the second word enters store 1 and moving on to store 3 when the second word enters store 2 and the third word enters store 1. When the first word is in the first store 1 each bit is compared with all the other bits. When the second word is in the first store 1 each bit of the second word is compared with all the bits of the first word and of the second word. Similarly when the third word is in store 1 its bits are compared with the bits of all three words. Whenever the comparator indicates coincident " l's " a latch is set in the weighting circuits 4a-4j each having thirty latches. This setting constitutes the " learning " operation. In the recognizing operation the successive words are entered in the three stores as before and the thirty bits applied to each of the ten circuits 4a-4j. The output of each is summed 9a-9j and a threshhold circuit 10a 10j indicates whether or not a certain match exists. The ten outputs are gated with the ten bits of store 1 representing successively the three words. The outputs of the gates 11a 11j are summed and the resulting value divided by the summation of the " l's " in the first store to produce a match signal which will be " I " for a perfect match. The prediction circuit, Fig. 4, may be connected to the threshold circuits 10a-10j by switch 41a-41j to enter in store 44 the corresponding outputs. If the first two words are in stores 1 and 2 the word entered in register 44 is the predicted third word of the learned pattern. The prediction is tested by passing the word in store 44 back via gates 45 and cable 50 to store 1 so that the originally entered words move to stores 2 and 3. The resultant outputs of the threshold circuits again enter store 44 and the stored word is compared in gates 46a-46j with the contents of store 1. If they are the same the prediction was correct. The outputs of the gates 46a-46j should all be zero. Gate 48 passes them to OR gate 49 and a zero response causes circuit 51 to produce an output to circuit 52 to indicate a correct prediction. A modification is suggested whereby the second of three words could be predicted if it were missing.

[Class 39 (i)] An incandescent screen comprises a mosaic layer which, to obtain low thermal conduction, is arranged on an organic cell-structure composed of a material of high melting point. Organic tissue, e.g. elder pith, is boiled in a solution of sodium tungstate, tungsten oxide is precipitated by adding a suitable precipitant, and the tissue is submitted to slow combustion to form a cell-structure of tungsten oxide which is reduced to tungsten by heating in hydrogen. The cell-structure may consist of carbonized velvet, or of tungsten or tantalum or carbides thereof. A reduced copy of a drawing of the mosaic screen may be prepared on a metal or cellulose plate in such manner that a depression is produced which corresponds to each mosaic element. A paste containing the material of the mosaic is placed in the depressions. The plate is then placed on the cellstructure and is removed by etching, treatment in a gas or by evaporation to leave the paste which is reduced to metal by heating in hydrogen. The screen is bombarded by electrons to sinter the mosaic elements and to evaporate a part of the cell-structure between the mosaic elements to increase the thermal insulation therebetween.
