Title: Process and apparatus for the production of pressure hose
IPC: B29D23/00
Filed: 1956-01-16
Abstract: 786,602. Hose pipes. VOHRER, H. Jan. 16, 1956 [Jan. 21, 1955], No. 1382/56. Class 99(2). A process for the production of a pressure hose including hose having a synthetic rubber base comprises applying at least one layer of fabric on to a vulcanised hose in order to obtain the pressure resisting strength applying to this fabric a mixture of polyvinyl chloride and a softener and coagulating this mixture by applying heat. The apparatus used comprises a braiding machine for applying at least one fabric layer on to the vulcanised hose, a heating tube with for example infra-red heating through which the prepared hose is run and a withdrawal wheel arranged at the end of the heating tube and coupled with the braiding machine. The heating tube may be automatically switched off and on as the machine is stopped and started up again. The hose while still hot on leaving the heating tube is drawn through a metal nozzle which removes unevenness. The nozzle may be heated to the coagulation temperature of the polyvinyl chloride. The hose may be made from a butadiene acrylnitrilic product of polymerisation and may be passed through a vessel containing a polyvinyl chloride paste before being drawn into a vertical braiding machine. A nozzle stripper removes surplus paste. The hose may have several layers with polyvinyl chloride as a binding agent so as to protect the fabric on the outer side the hose is covered with plastic substances. For this purpose plastics based on polyurethane which are known under the Registered Trade Mark of "Vulkolan" may be used. A coating can also comprise a polyvinyl chloride paste.

Abstract: 368,001. Changing signs. WALSH, J. Y., Cavendish Road, Eccles, Lancashire. Jan. 21, 1931, Nos. 1973 and 10442. [Class 3 (i).] A display band A wound on and off two rollers B<1> by an electric motor is stopped at each new display by projections a on the band which engage and tilt a metal lever D pivoted to the casing B. The lever D is normally in engagement with two fingers d<1>, d<2> which are pressed against the lever by springs d. The fingers d<1>, d2 and lever D form part of the circuit of the driving motor, and when the lever D is tilted contact with one of the fingers is broken and the motor stopped. The motor is re-started by a time switch which comes into operation immediately the circuit is broken and does not allow the motor to re-start till after a determined interval, although the projection a has moved slightly beyond the lever D and the latter has resumed its normal position touching both fingers d<1>, d<2>. The band A is reversed after each traverse by a metal strip on the band contacting with two spring-pressed pins, thus completing a circuit which reverses the motor.

[Also in Group XL (b)] A single-gun cathode-ray tube for use in a simultaneous colour television system (see Group XL (b)) of the type in which the screen is made up of a regularly repeating sequence of blue, green and red phosphor strips 12, 13, 14 scanned with the line direction transverse the strips, incorporates additional metallic strips 15 deposited over each group of three phosphors and which serve to produce synchronizing signals to control the application of colour signals to the tube gun in step with the scanning. The metallic strips are connected together by transverse end strips (not shown) in two sets of alternate strips (so forming a structure in the form of a pair of interleaved combs) and connections from the two sets are brought out through the tube envelope. To ensure accurate operation at the beginning of each line scan, a small number of metallic strips 15 is included which are traversed before the scanning beam reaches the screen proper. Reference is made without giving details to arrangements in which (1) the metallic strips have widths corresponding to more than a single group of three strips; (2) the phosphors are of different widths to compensate for their different efficiencies; (3) the spacing of the phosphors is varied to allow for a non-linear line scan; and (4) the colour phosphors are replaced by a white phosphor and a coloured optical strip filter.

A three-phase motor is started by actuating a push-button to operate a contactor having contacts 1M1, 1M2, 1M3, whereby resistors R1, R2, R3 are connected in series with line conductors L1, L2, L3, and resistors R4, R5, R6, form part of a delta network comprising the stator phase windings 11, 12, 13. After a time interval, contacts 2M1, 2M2, 2M3, are closed to shunt the resistors R1, R2, R3, thus leaving the resistors R4, R5, R6, in series with the phase windings of the motor. The contacts 1M1, 1M2, 1M3 are opened after a further time delay and contacts 3M1, 3M2, 3M3 are closed to form parallel combinations of resistors Rl-R6, each combination being in series with a phase winding. The contacts 1M1, 1M2, 1M3 are then reclosed to connect the stator windings directly across the power conductors, so completing the starting sequence. The resistors may be replaced by reactors.

Title: Improvements in and relating to electromagnetic firing gear for guns
IPC: F41A19/59
Filed: 1926-01-29
Abstract: 271,925. Scott, H. G. A. Jan. 29, 1926. Addition to 224,319. Ordnance b r e e c h mechanism; discharging by means external to breech mechanism.-Relates to electromagnetic firing mechanism comprising an electromagnet normally holding the striker in the cocked position, and an electromagnetic safety device adapted to move out of the safety position before the circuit of the electromagnet holding the striker is broken to release the striker when a firing switch is operated, as described in the parent Specification. According to the invention, the firing switch closes the circuit of the electromagnet of a safety sear to move this device out of the way of the striker, and the movement of the sear positively breaks the circuit of the electromagnet holding the striker; and the circuit of this electromagnet is automatically made when the breech is closed. In the form shown in Fig. 1. the striker 7 is held cocked by an electromagnet 3, while a safety sear 5 lies in front of but not in contact with a projection 15 on the striker. The electromagnet 3 is energized from a source A through switches 22, 23 adapted to be closed when the breech is closed. The sear 5 is mounted on a spindle 11 connected, to the armature 12 of an electromagnet 19, and is held in this safe position by a spring 16. When a firing switch 24 is closed, The electromagnet 19 attracts the armature 12, causing the sear 5 to move out of the safety position; and immediately thereafter the armature 12 engages a contact 1 and moves it away from another contact 2, thereby breaking the circuit of the electromagnet 3. A cocking lever 10 bearing on a projection 21 on the striker and on a projection 8 on the spindle 11 serves to cock the striker and to move the safety sear to the safety position. In a modification, the electromagnet holding the striker performs this function by means of a lever pivoted on the same pivot as the cocking lever and having a limited rocking movement relatively thereto. In another modification, the safety sear carries a movable catch normally out of the way of a bent on the striker, and is thrown into the safety position by a bevelled part on the striker and held in that position by a spring. When the safety electromagnet is energized, the movable catch is pressed against the striker, and when the striker begins to move forward it bears on the movable catch and deflects the sear out of the safety position. In still another modification, Fig. V, a sear 40 is pivoted at 41 on the striker 7 and is held behind a bent 43 by a spring 42 after having been swung to the safety position by a cam face 46 during the overcock of the striker. The safety electromagnet when energized rocks a lever 44. which deflects the sear 40 away from the bent 43.
