Title: Braun tube, more particularly for television purposes
IPC: H01J29/52
Filed: 1933-07-08
Abstract: 423,793. Cathode ray tubes; television. ARDENNE, M. VON, 19, Jungfernstieg, Lichterfelde-Ost, Berlin. July 8, 1933, No. 19385. Convention date, July 11, 1932. [Classes 39 (i) and 40 (iii)] In controlling the intensity of a cathode-ray by deflecting it magnetically to cause variable cut-off at a stop or shutter, the deflection is produced at a point where the electrons have a constant velocity. The deflecting coil 1 and a compensating deflecting coil 2 are arranged in front of and behind the shutter 3 which is inside, and is connected to, an anode tube 5 with apertured end discs ensuring constant velocity of the electrons near the coils 1, 2. The main deflecting plates 6, 7 are also arranged inside the tube 5 to shield them from electrons returning from the screen 9. The coils 1, 2 are in vacuum-tight enclosures and are wound of very thin wire to have a natural frequency of 10<6> oscillations per second and to produce the deflections with currents of 10 milliamps. The coil 1 may be inserted in the anode circuit of the last stage of the receiver, a potentiometer in the grid circuit adjusting the current through the coil and so the position of the ray relatively to the shutter 3. Alternatively, the coil 1 as well as the coil 2 carries only alternating current, the ray being adjusted by a small external magnet. To avoid electrostatic action of the coils 1, 2 on the ray, the coils are connected to the tube 5 and are screened from the ray by a grid 10.

In a balancing apparatus of the type described in the parent Specification 968,558, wherein a rotatable assembly 16 including an element such as a grinding-wheel 20 is normally supported for rotation about a fixed axis by engagement with a rotatable support 13 and is moved axially away from the support 13 for balancing during which it is supported by a resilient rod 21, additional support and stabilizing means 40 are provided to prevent excessive whirling during balancing. The support comprises a shoe 48 urged by mechanical or fluid spring means (55) towards an extension 31 of the rotatable assembly. A stop (51) prevents the shoe 48 engaging the extension 31 when the rotating assembly engages the support 13. As shown, the shoe 48 is fast with a lever 47 pivoted on a fixed block 45 and a helical compression spring (55) acts between the block and lever 47 to urge the shoe 48 towards the extension 31. The rate of the spring 45 is negligible compared with the spring rate of the rod 21 and thus has negligible effect on the balancing.

Title: Method of and device for applying an end winding at the top of wound weft bobbins and cops
IPC: B65H65/00
Filed: 1959-06-08
Abstract: 912,621. Winding yarns. MASCHINENFABRIK SCHWEITER A.G. June 8, 1959 [June 10, 1958], No. 19571/59. Class 120 (2). A method of forming a separate end winding at the end of a wound weft bobbin is characterized by the fact that the yarn is continuously wound directly on to the bobbin at one point so as to form a groove at the centre of the winding and continuing the winding so that the turns forming the sides of the groove cover the yarn in the groove, thereby holding the end winding against unwinding. As shown, a device for carrying out the above method comprises a yarn guide plate 11, a member 14 for forming a groove in the end winding and a checking pin 12 limiting the width of the end winding. On completion of winding 16 the yarn guide 17 is swivelled out of normal winding position towards the end winding device which has been previously swivelled into operative position (Fig. 2). The first layers of the end winding are applied on the entry side of the yarn guide plate 11 and subsequently the yarn slips under the separating member 14 and winds on the other side. The yarn is wound on the bare bobbin tube in the groove formed by the winding separator member such that the windings are continuously displaced by the additional windings and thereby slipped underneath the windings already present on the bobbin tube. The device for the formation of the end winding comprises a holder 4a to which is rotatably connected a spindle 5 carrying a one-armed lever 6. Also carried by spindle 5 is a two-armed lever 8 which carries an adjusting- screw 9 at one end and at the other end is connected to a tension-spring 10 and a pressure-bar 10a which moves the device into operative position. On the lever 6 is the yarn guide-plate 11 which supports the checking-pin 12 and the winding separator member 14.

Title: Improvements in or relating to the manufacture of prestressed concrete articles
IPC: E04C5/10
Filed: 1952-08-06
Abstract: 721,178. Prestressed concrete. PRELOAD CO., Inc. Aug. 6, 1952, No. 19839/52. Classes 20 (2) and 20 (4). [Also in Group V] Relates to the making of prestressed concrete girders, &c., by forming a channel in the concrete with the aid of a flexible tube, allowing the concrete to harden, inserting the prestressing units into the channel and stressing them. According to the invention, one or more annular friction-reducing members of metal are placed on the flexible tube and are left in the concrete when the tube is removed to lessen friction between the units and the walls of the channel. Fig. 1 shows the flexible tube in the form of a rubber hose 1 fitted with steel rings 2. The hose is inflated by air or liquid prior to hardening of the concrete, and a wire spiral 4 embedded within the hose walls forms ridges as shown, these ridges facilitating bonding between the concrete and cement slurry which is introduced later with the prestressing units. The rings may be replaced by a metal sleeve, Fig. 2 (not shown), or by double tubular sheet metal pieces having an intermediate layer of lubricant.

Title: Hole count checker
IPC: G06F3/08
Filed: 1963-05-20
Abstract: 964, 491. Statistical apparatus. SPERRY RAND CORPORATION. May 20, 1963 [May 31, 1962], No. 19885/63. Headings G4A and G4M. The operation of punching apparatus or a reader is checked by counting each pulse corresponding to a hole which is supplied to the punching apparatus or derived from the reader, passing the perforated record medium through a further reader and subtracting each pulse delivered by this further reader from the stored count. If the stored count is not reduced to zero an indication is given that there may not be a fault in the apparatus (two complementary faults not being detected). When the operation of a punched card reader is to be checked, the card is sensed row-by-row by the reader, the output of which is serialized and applied to input A. Assuming N clock pulses to occur between successive pulses at input A, the recirculating accumulator comprising add network 14, inhibit gate 16, pulse formers 18, 22 and delay line 20 has a total recirculation time equal to the time occupied by N clock pulses. A first pulse at input A passes through OR gate 10, is delayed by one clock pulse interval in pulseformer 12 and then recirculates round the accumulator to appear at the other input to add network 14 when the next pulse issues from pulseformer 12. The sum output is recirculated, whilst a carry pulse is inserted via OR gate 10 and pulseformer 12 in the next higher denominational position i.e. one clock pulse period later. When the sensing (or punching) operation has been completed, N pulses are applied on conductor 24, gate 34 being inhibited to clear a subtracting accumulator of previously stored information, gate 26 being opened to transfer the hole count from the adding accumulator to the subtracting accumulator, and gate 16 being inhibited to clear the adding accumulator so that a following card may be sensed (or punched). At the appropriate time in the clock pulse cycle the second reader starts to apply pulses to input B, and these are subtracted from the count already circulating. At the end of the second reading operation, which corresponds with the sensing of the following card, any count remaining in the subtracting accumulator causes bi-stable circuit 52 to be set to indicate an error in sensing (or punching) the card.

Filed: 1945-08-03
Abstract: 596,888. Testing physical qualities of material. HAMMOND, A. B. Aug. 3, 1945, No. 20001.' [Class 106 (ii)] In a tensile testing machine having a load indicator and a drive for the straining-device, an electrical condenser 10 associated with the straining-device 7, 9 is so arranged that on any variation in the capacity thereof due to alteration in the rate of straining or loading the load is automatically increased or decreased as required to restore the capacity of the condenser to its former value whereby the rate of loading of the test-piece is maintained constant. A motor 5 drives gearing 6 to rotate screws 1, 2 with which a bar 7 has screwthreaded engagement, and the test-piece 8 is secured at its ends to the bar 7 and a spring 9. An indicator connected to the spring 9 registers the load applied. One plate of the condenser 10 is connected to the spring 9, and the other plate is connected so as to be moved by a motor 11, the arrangement being such that uniform movement of the spring 9 due to uniform stretching of the test-piece 8 will not vary the distance between the condenser plates. The condenser may be connected to the motor 5 through a valve relay circuit employing gasfilled valves, a bridge network, photo-electric cells and a mirror galvanometer. If, due to a sudden extension of the test-piece, such as when the elastic limit has been reached, or a stiffening of the material, the load on the testpiece decreases or increases the distance between the condenser plates will vary, and the change in capacity will be communicated to the valve relay which will correct the speed of the motor 5 and restore the plates of the condenser to normal.

Abstract: 695,274. Check-freed meters. BOWSER, Inc. July 29, 1949 [Aug. 18, 1948]. No. 20003/49. Class 27. Delivery by meter. Coin action, thrust; coin moved by rotary member to disengage detent therefrom. A disc 79 (Figs. 3 and 7) mounted between fixed plates 31, 27 and driven through gearing from the meter of a petrol pump or the like is' permitted to make a half revolution, corresponding to delivery of 50 gallons from the pump, upon insertion of a check. The check is placed in a slot 101 (Fig. 7) in a magazine 89 after a sliding plunger 95 on a rod 93 has been drawn back against a spring 99 by pulling a knob 97. The spring 99 then causes the plunger 95 to press the check through a hole in the plate 31 into a check receiving hole 81 in the disc 79 so that the check presses a sliding detent 117 out of the hole 81 against a spring 121. This releases a lever 109 carrying the detent 117 to turn about its pivot 107 (Fig. 3) under the influence of a spring 124 and close a switch making the pump available for delivery. After 50 gallons have been delivered so that the disc 79 has turned through half a revolution a second hole 81 in the disc 79 registers with the magazine 89 and, if the magazine contains no checks, engages by its bevelled edge 83 the detent 117 so turning the lever 109 to open the switch controlling the pump. Checks stored in the magazine 89 are visible through a cut-away portion 103 provided with a cover 105. Coin discharging; registering. When the disc 79 has completed half a revolution the hole 81 containing a check is brought into register with holes in the fixed plates 32, 27 so that a roller 154 (Fig. 3) carried by a spring-biased lever 141, 143 pivoted at 140 can push the check out of the disc 79 to fall into a check-receiving box. The lever 141, 143 operates a register. Fraud, preventing. If the detent 117 is depressed by manipulation of a tool inserted through the slot 103 the pump is available only until the rotation of the disc 79 causes the edge of the hole 81 to engage a second sliding detent 115 (Figs. 3 and 7) on the lever 109. The apparatus may then be freed for operation by depressing the detent 115 by insertion of a tool through a hole 32 in the fixed plate 31, which hole is accessible only after partially disassembling the mechanism.
