Title: Logic circuits
IPC: H03K19/098
Filed: 1971-08-03
Abstract: 1341302 Code conversions COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 3 Aug 1971 [3 Aug 1970 21 Oct 1970] 36397/71 Heading G4H [Also in Division H3] A transcoder Fig. 5 has 30 logic circuits P1- P30 in which each logic circuit has two seriesconnected thyristors A1, B1 the first input e 1  being connected to the anode of the first, and the other inputs e 2 , e 3  being coupled to the gates. Capacitors are provided at the inputs to prevent spurious triggering of the thyristors. In the transcoder of Fig. 5 each logic circuit receives three inputs selected from eight pulse receiving positions E 0 -E c , a unique logic circuit producing an output for each different three-out-of eight coded signal received at E 0 -E c . Each logic circuit output is connected by a unique diode arrangement to a selection of five possible output terminals S1-S16 to give a binary coded signal, corresponding to the received input signal. Relays at S1-S16, to operate a mechanical logic system, are thus able to be driven directly by the logic circuits by virtue of the use of thyristors. An alternative transcoder (Fig. 6, not shown) changes a two-out-of-five code into a binary code.

Title: Automatic cut off for electrically operated typewriters
IPC: B41J29/387
Filed: 1955-12-23
Abstract: 816,830. Typewriters. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 23, 1955 [Dec. 30, 1954], No. 36937/55. Class 100(4) A power driven typewriter having driving means controlled by an electrical switch 4 includes an automatic cut off device comprising a bracket 16 pivoted for movement from a rest position to an operative position and linked to the switch so that the latter is shut off when the bracket has been moved to its operative position, and actuating means carried by the bracket for rocking the latter from its rest position to its operative position after a predetermined uninterrupted period and comprising a pair of wheels of different diameters coaxially mounted on the bracket for rotation by the driving means while the bracket is in its rest position, means mounting one of the wheels for lateral movement in response to a predetermined continuous rotation of the wheels, and an actuating cam in response to this lateral movement for rocking the bracket to its operative position. With the bracket in the rest position driving wheel 18 and climbing wheel 22, of smaller diameter, are rotated by contact with power roll 2, and the latter wheel rotating at the faster rate rotates relatively to the threaded shaft 24 and moves along that thread, and after a predetermined time, if the typewriter is not operated, engages cam 20 and rotates it slightly against the pull of spring 49. Cam 20 then engages and is driven by roll 2, until the widest part of the cam leaves the roll, and finally returns to its rest position under its own momentum. As the cam is thus driven it causes bracket 16 to rock clockwise, Fig. 1, about stud 28, and through link 50 operate switch 4 to shut off the motor (not shown). The cutoff mechanism is disabled by operation of certain typewriter function keys which reset the climbing wheel to its rest position. Thus, for example, operation of the case shift key 56 rotates plate 58 counterclockwise, Fig. 1, and via pin 62, yoke 63, and arm 54 rocks the bracket slightly to interrupt the drive between roll 2 and wheel 22, whereupon spring 26 moves wheel 22 axially to its start position. Switch 4 may be operated manually by means of arm 8 acting through link 6. Specifications 655,492 and 773,939 are referred to.

Abstract: 900,287. Gas burners. GEDDES, L. S. Feb. 17, 1960 [Nov. 18, 1958], No. 36998/58. Class 75(1). A gas burner comprises a plurality of nozzles 2, of different flame characteristics, means for supplying a combustible mixture of gas and oxygen to a selected nozzle and valve means for controlling the proportion of gas and oxygen in the mixture in accordance with the selected nozzle. The two means are operated simultaneously. The nozzles 2 extend from a chamber 3 in a head 1. A spindle 7 projects through the head 1, a nozzle selector 4, a body member 5 and a knob 6 and is fast with the selector 4 and the knob 6 but is free to rotate in the head 1 and body member 5. The body member contains a valve 15 controlling the flow of oxygen from an inlet 10 through a duct 19 in the body member to ports 20 in the spindle 7 leading to a nozzle 18 directing the oxygen into a Venturi 21 formed in the spindle 7. The gas enters the body at 11 and flows through ports 17 into the spindle 7 to mix with the oxygen in the Venturi 21. The mixture flows through a port 22 in the spindle 7 to the selector disc 4 and then to the selected nozzle. The oxygen valve 15 is opened against the action of a spring 16 by the ends of pins 13 screwed into the knob 6 to project therefrom by different amounts and to engage the end 14 of the spindle of the valve 15. In another embodiment, Fig. 4 (not shown), the body 5 also contains a valve for controlling the flow of fuel gas to the Venturi and the knob 6 has circumferentially arranged flats adapted to open the gas valve by different amounts. In another embodiment, Fig. 3 (not shown), the Venturi is formed in the body 5 and its discharge end communicates with an annular chamber in the selector disc 4. A pilot burner is provided in the head 1. In another embodiment, Fig. 2 (not shown), the Venturi is again formed in the body 5 and the oxygen is carried downwards through the spindle 7 into the knob 6 which is provided with a plurality of oxygen valves each having a discharge passage adapted in one position of the knob to register with an inlet in the body 5 leading to the Venturi. In the embodiment shown in Fig. 5 the selector disc 4 is coupled by a pin 68 to a cam member 69 equivalent to the knob 6 of the previous embodiments and having screwed pins 70 for actuating an oxygen valve 72 in the body 5, and steps 74 for actuating a fuel gas valve 76 also in the body 5. In the embodiment shown in Fig. 6, each of three nozzles has a mixing chamber 95 and a rotary valve conveys fuel gas to a selected one of three ducts 101 leading to a mixing chamber and oxygen to a selected one of three ducts 104 also leading to a mixing chamber. A needle valve controls the oxygen flow in each duct 104. In the embodiment shown in Fig. 8 the burner has two nozzles and two ducts convey oxygen from separate needle valves to a mixing chamber 116 in a rotary selector 110. Fuel gas is conveyed to the mixing chamber 116 by a single duct (not shown).

Title: Method and apparatus for treating yarns
IPC: D02G1/20
Filed: 1971-08-06
Abstract: 1348831 Heat shrinking yarns ROSENKRANZ & CO GmbH 6 Aug 1971 [7 Aug 1970] 37084/71 Heading D1F A method of heat-shrinking yarn comprises passing the yarn in a looped path through a heating chamber, the descending and rising loop portions being not allowed to touch the chamber walls, and the quantity of yarn in the chamber being regulated by altering the relative speeds of feed and withdrawal rollers. The chamber may be heated by radiant heat, by superheated or saturated steam, by air at 100 to 250C, by water at 60 to 100C, or by mixtures thereof. The treatment may comprise, Fig. 1, feeding yarn 1 in the form of loop 9 through heating chamber 8. The chamber is heated by radiant heater 8', and the yarn is subject to suction via a channel 14 which serves several chambers. The shortening of the loop, due to shrinkage of the yarn, is sensed by light cell 18 which accelerates yarn feed device 5 to thereby maintain constant the loop length and the yarn quantity in the chamber. When the loop shortens cell 18 causes electromagnet 20 to press roller 21 between roller 6 of device 5 and roller 22, so allowing roller 22 to accelerate device 5. When the loop lengthens, cell 18 decelerates device 5. The chamber may be heated by steam, at a pressure of 0.1 to 1 atmospheres above atmospheric pressure, fed into the chamber top by a perforated annular tube (Fig. 4, not shown). The yarn may be fed into the chamber in a pipe in which it is entrained by hot fluid, and withdrawn in a pipe in which it may be bulked by steam or dried by hot air (Fig. 5, not shown). In an alternative method, Fig. 6, the yarn is fed with hot fluid from oscillating tube 58 and sucked against sieve 57. The quantity of material in the chamber is regulated by sensing the pressure in space 62 above suction channel 56. As the yarn begins to cover the sieve the pressure in space 62 falls, and at a pre-set pressure monitoring pressure regulator 65 accelerates yarn withdrawal device 65. The device is decelerated when the pressure in space 62 increases and the quantity of yarn on the sieve decreases. In a modification, Fig. 7, the yarn is deposited on a moving continuous perforated steel or plastics belt 74. If yarn accumulates in the chamber so that it is carried by the belt against lever 93, the lever is pivoted to close contacts 97 and accelerate withdrawal device 103. Yarn supply tube 85 is oscillated across the belt. In a further method (Fig. 3, not shown) the yarn loop bottom extends below the chamber and passes under a hook controlling a winding speed regulator.
