Title: Improvements in or relating to sorting machines for perforated cards
IPC: G06F7/06
Filed: 1931-06-02
Abstract: 377,366. Statistical machines. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. June 2, 1931, No. 16113. Convention date, June 3, 1930. Addition to 359,073. [Class 106 (i).] Sorting cards.-In a sorting machine for perforated statistical cards the card-guiding means, which consist of flexible bands or threads o1 .. o12 normally lying in one and the same card-transporting plane, are inseparably connected to controlling levers m1 .. m12 therefor which are situated outside the card path. The code card a energizes one or more of the four magnets b1 .. b4 which, through armatures c1 .. c4, move the corresponding bars d1 .. d4 longitudinally. These bars are notched so that for each setting or card-reading only that one of twelve levers e can fall which is opposite the row of four aligned notches. The levers e, pivoted at f, have fingers l coacting with the members m1 .. m12 attached to the sorting wires o. For each sorting box there is a pair of members m1 &c., one on each side, joined to a pair of wires o1 and o<1>1 &c. If desired each pair of members may be joined by a central piece as in the case of m2 .. m12, Fig. 2, to form a stirrup. Cams k, s and springs g, u control the levers e and members m so that when a card is read the appropriate lever e is allowed by bars d1 .. d4 to rock clockwise, Fig. 1, and raise the appropriate pair of members m. Each member m has a lug p or pl underlying the adjacent member so that when a member, say m6, is lifted it lifts the following members m7 .. m12 with it, so as to sort the card into the correct box.

Abstract: 864,269. Pneumatic gauges. SHEFFIELD CORPORATION. May 20,1958 [May 24, 1957], No. 16138/58. Class 106 (2). A pneumatic gauging circuit has a source of air under positive pressure which is connected by way of a pair of gauging passages 12 and 14 to a gauging head 20 and thus provides differential air flows through the passages 12, 14 with a differential measuring tube 30 responsive to the air flows, there being a flow through the tube 30 between the passages 12, 14. Air is supplied to a pressure regulator 10 from which it branches into the passages 12, 14. The passage 12 leads past an adjustable equalization restriction 15 through an insert 57 and out of the forward face of the instrument through a shut-off valve 44 to the head 20. The passage 14 leads past a fixed restriction 16 through a shut-off valve 45 to the head 20. The tube 30 is connected between the passages 12, 14 downstream of the respective restrictions, and is a vertically tapered transparent tube which contains an indicating float 33 adapted to be positioned vertically in accordance with the air flow through the tube. An adjustable relief to atmosphere 40, controlled by knob 41, is provided downstream of the flow tube 32 between the upper end of the tube and its communication with the passage 12. There is also an adjustable restriction 35, controlled by a knob 36, at the lower end of the tube 30. Fig. 2 is a diagram of the circuit of the instrument applied to measuring the centre distance between holes 21, 22 in a part 25. In the set-up procedure master workpieces with maximum and minimum allowable centre distances are alternately applied and adjustments 41, 36 conjointly adjusted so that float 33 arrives opposite maximum and minimum pointers 51 and 52 (Fig. 1, not shown) respectively. The gauging circuits must also be properly balanced so that when the minimum centre distance master is placed in position with valve 45 closed the rise of float 33 above the minimum pointer 52 must be the same as the distance of float 33 below the maximum pointer 51 when the maximum centre distance master is placed in position with the upper valve 44 closed. If the displacements are not equal adjustment of restriction 15 is necessary.

Abstract: 1,007,398. Welding by fusion. COMMISSARIAT A L'ENERGIE ATOMIQUE. April 20, 1964 [May 9, 1963], No. 16205/64. Heading B3R. [Also in Divisions F2 and H1]  A pipe 3 which is to be welded by an electron beam to another pipe in a vacuum enclosure 1 is sealed in an aperture at one end of the enclosure by means of an elastic membrane 6 which is secured at its beaded edges 7, 8 between a flanged sleeve 10 and a rim 9 defining with the casing and the membrane annular chambers 14, 15 which communicate with each other through holes in the rim 9. A gaseous fluid is introduced under pressure through the chambers via a connection 35 and ducts 17, 18 in order to force the membrane 6 into sealing contact with the pipe 3. The degree of pressurization is controlled by the spring load applied on a piston in a connector 33 by means of a knurled screw cap 32. When the pipe is introduced or removed from the enclosure, the chambers 14, 15 are depressurized causing the membrane 6 to retract leaving a free passageway for the pipe. After introduction into the enclosure, the pipe is locked relative to the sleeve 10 by means of clamping jaws 26 fitted with hand-levers 27 adapted to co-operate with stops 28 on the sleeve. The latter is supported in a ball bearing 19 and is rotated to cause rotation of the pipe 3 during welding by means of a pinion 29 engaging its flanged end and driven by a wormscrew 30. The pinion 29 is mounted on a shaft 29a which serves to transmit motion to the other pipe introduced into the enclosure at its other end. Dynamic seals 23 are provided between the sleeve 10 and a member 21 secured to the enclosure.

Abstract: 480,156. Igniting gas burners. HORSTMANN, B. G., and HORSTMANN GEAR CO., Ltd. June 11, 1937, No. 16283. [Class 75 (iii)] [Also in Group XXIX] In means for igniting the burners of a stove &c. on opening the gas tap, the handle 2 of each gas tap 1 is secured to a cam plate 7 attached by screws 8, 9 to a sleeve 4 on the plug 3. 'The screw 9 co-operates with an arcuate slot 10 in the plate to allow the handle 2 to be turned about the pivot screw 8 through an angle of about 45 without moving the plug 3. During this movement, the arcuate edge 11 of the. plated 7 actuates a lever arm 12 to rock a shaft 13 and, at the end of the movement, the edge 11 is concentric with the plug 3, which is opened by further movement of the handle. The shaft 13 actuates through a lever 23 a spring-pressed plunger 19 in a casing 16 to open a pilot valve 18 and bridge contacts 22 to close the circuit of an electric igniter. A pilot burner, having two or more nozzles adapted to produce long flames for igniting any of the burners, may be located at the point 15. On releasing the handle, the plunger 19 is returned by its spring and causes the handle to turn backwards about the pivot screw 8 without turning the plug 3.

In an AFC circuit in horizontal scanning of a television receiver shown a horizontal flyback pulse fed to input Ti is integrated by R6, C2 to form a sawtooth wave. If a horizontal synchronizing signal of negative polarity is applied at To the transistor Q3 is turned off to make the transistors Q1 and Q2 on. The sawtooth voltage applied to e during the period of every synchronizing pulse is obtained at the output terminal To. The obtained sampling signal may be integrated to produce a control signal for controlling the oscillation frequency of a horizontal oscillator circuit. In a modification (Fig. 4, not shown) the control transistor Q3 is connected in place of the resistor R 4 . The circuit may be formed as an integrated circuit and can be used in a signal sampling circuit.

Abstract: 938,572. Aerials. H. EHRENSPECK. May 11, 1960 [May 11, 1959], No. 16689/60. Class 40 (7). The gain of a surface wave aerial, such as a Yagi array, is increased by providing means which ensure that at least some of the radiation from the feed point traverses the array twice. The method is stated to be applicable to all types of surface wave aerials, e.g. dielectric rod aerials. In a first embodiment, Fig. 2, a Yagi array, comprising a fed dipole, a reflector R and a number of directors D, has a reflecting plate M placed as indicated. This aerial radiates in the direction opposite to that in which the Yagi array would radiate, due to the presence of reflector M. The gain and directivity of the array exceeds that of the component Yagi. In a second embodiment, Fig. 4, the array is formed of a Yagi comprising a dipole, directors D, and a reflecting plate M, a reflector R being placed in front of the directors. In this arrangement some of the energy radiated by the Yagi array is reflected by R back to M, where it is again reflected, providing constructive interference with the main radiation lobe. The aerial may be flush-mounted, Fig. 3 (not shown), and the reflecting plate may comprise a flat or slightly curved plate, mesh screen, linear elements parallel or radially mounted, or metallized plastic. It is stated that the reflector R may be formed of like materials.
