Title: Improvements in reinforced cylinders and methods of producing the same
IPC: B21F17/00
Filed: 1941-10-06
Abstract: 548,483. Making gas cylinders. BRIDGES, W. Oct. 6, 1941, No. 12874. Addition to 544,952. [Classes 83 (ii) and 83 (iv)] Soldering.-In making a wire reinforced cylinder by hooking the end of the wire round a projection on a ring carried by the cylinder and then winding the wire round the cylinder and securing the other end to another projection on the same ring or to another ring at the opposite end of the cylinder, as described in the parent Specification, the turns are secured together by rotating the cylinder in a hot solder bath and brushing the winding with flux until the solder flows evenly thereamong. The wire may consist of piano wire so as to reinforce a cylinder containing compressed air, oxygen &c., against fracture from projectiles as well as internal pressure. The ends of the reinforcement, which is preferably of tinned wire, may be secured to lugs 14a, 14b both on one of the rings 11 or one on ring 11 and the other on ring 12. The lugs are bent down after hooking the ends of the wire thereon. Finally the flanges on the rings.are turned over the end windings. The cylinder is then placed between an adjustable centre 24 and a chuck 25 carried by a frame 23 which is provided with a pair of handles 42, 30 so that it may be lifted over a solder bath. The sides 23a rest on the flanges 27 of the solder bath and the sides 23b have bolts 28 engaging the flanges. The cylinder is rotated with the wire reinforcement dipping in the solder, by driving the chuck 25 through a chain and sprockets from a handle 41. The chuck spindle is carried by ball and thrust bearings in the support 32 carried by the frame 23. The solder bath is heated preferably electrically and a brush dipped in a flux bath preferably associated with the solder bath, is applied to the reinforcement until the solder flows evenly among the windings. The cylinder is finally washed in a hot water bath. Specifications 548,480, 548,481 and 548,482 are referred to.

Title: Improvements in or relating to cinematograph projectors
IPC: G03B1/40
Filed: 1960-04-12
Abstract: 893,618. Film projectors. BAUER G.m.b.H., EUGEN. April 12, 1960 [Jan. 22, 1960], No. 12977/60. Class 97(1). A cinematographic projector has a take-up shaft which is driven by a function clutch in which means are provided which, when the projector is started, for a short time increase the bearing pressure of the friction clutch beyond the value determined by the weight of the spooled film and its reel and thereafter become inoperative again. In the take-up spool control means shown in Fig. 2 the spool 16 is mounted on a shaft 17 which is pivotably mounted on one end of a lever 26 which in turn is pivotably mounted on a shaft 27 and has at the other end a friction disc 28 which engages the internal surface of a friction drum 22 which is driven by motor 25. The lever 26 has a pressure lever 29 attached to it which is connected by a spring to the armature of an electromagnet 31. The motor 25 is started by a push button operating through a relay device. Simultaneously, the relay starts a motor for feeding the film and also energizes the electromagnet 31 so that the spring contracts to rotate the lever 26 and the contact pressure in the friction clutch 23, 28, and hence the speed of the take-up spool, is increased. When the motor has reached a preselected speed, the coil of the electromagnet is de-energized but by means of a timed relay the release of the clutch control is delayed for a brief period. In another embodiment shown in Fig. 4 the lever 26 is connected via a lever 64, strap 65, lever 66 and pin 69 to a lever 70 which has rollers 72, 73 in the path of the film and which is rotatable about a pivot 71. When the film is loose a spring 76 urges the lever 70 upwards and a force acting through the levers 66, 64 increases the pressure in the clutch. When the film is tight it pushes the lever 70 down to reduce said pressure. The lever 26 may be positioned so that part of the weight of the spool and film is carried by the pivot 27 (Fig. 2) and not by the friction clutch.

Title: Improvements in and relating to stabilizers for long distance alternating current power transmission systems
IPC: H02P9/10
Filed: 1948-05-12
Abstract: 653,859. Transmission line arrangements. BRITISH THOMSON-HOUSTON CO., Ltd. May 12, 1948, No. 13048. Convention date, May 13, 1947. [Class 38 (iv)] To improve the stability of a long A.C. transmission line interconnecting synchronous machinery, a variable reactive load is connected to the line, say at the transmitting end, or at a point intermediate the transmitting end and the receiving end, and the magnitude of this load is controlled by electronic means in response to conditions indicative of instability, such as variations in phase angle between the machines at the two ends of the line. In the system shown in Fig. 4, a machine 1 supplies a synchronous machine 9 over a long line 8 which is stabilized by reactors 23 at the transmitting end of the line, the reactor current being automatically controlled by a three-phase bridge 16 of phase-controlled rectifiers 17 shortcircuited on their D.C. side by a conductor 21. The control potentials for the rectifiers are derived, through transformer 26 and phaseshifter 27, from current transformers 30 at the transmitting end of the line, these transformers providing a voltage output which is definitely related in phase to the voltage obtaining at the receiving end of the line. Alternatively, the phase of the grid control voltages may be varied in accordance with the phase of the voltages at the receiving end of the line through a communication channel or correspondence control system interconnecting the transmitting and receiving ends of the line. Capacitors may also be connected to the line and may serve to excite the machine 1 when this is of the induction generator type.

Title: Improvements in and relating to metal vapour rectifiers
IPC: H02H7/127
Filed: 1926-05-21
Abstract: 253,097. Akt.-Ges. Brown, Boveri, et Cie. June 2, 1925, [Convention date]. Vapour apparatus, arrangements of. - In order to prevent back ignition in rectifiers having anodes surrounded bv insulated metal sheaths, the sheaths or other metal parts, such as grids or rings, are connected to a separate transformer winding, the potential position of which with respect to the transformer winding feeding the anodes is controlled by a continuous voltage supply in such a way that the latter gives to each anode sheath a negative potential relatively to the corresponding anode, at least during the time in which the anode is not conducting current. As shown, the anode sheaths h' - - h<6> are connected with auxiliary secondary transformer windings Q<2> producing the same voltage as the secondary windings Q<1> supplying the anodes a<1> - - a<6>, and a continuous current supply, such as a battery B, is connected between the neutral points O<1>, O<2> so as to maintain each sheath at a potential lower than that of the corresponding anode. Resistances W<1> - - W<6> are connected between each phase and the sheaths so as to neutralize the rise in potential of the sheaths due to impact of ions. A high-loading resistance may be connected between the neutral of the auxiliary secondary windings and the cathode. Small inverse currents may be prevented by the provision of additional controlling cylinders inside the anode cylinders or sheaths, and one or both sets of cylinders may have an insulating coating. In a modification, the anodes are mounted in hollow arms extending from the container, and the sheaths are placed around the arms, the resistances W<1> - - W<6> being omitted. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an arrangement in which the battery is dispensed with, and the voltage supplied by the auxiliary windings to the cylinders is higher than that to the anodes, the neutral points not being connected together. With this arrangement the arc passes from an anode by way of its cylinder which is thereby given the same potential as the anode, and the cylinders of the anodes which are not carrying current are consequently maintained at a lower potential than the corresponding anodes. This subjectmatter does not appear in the Specification as accepted.

Abstract: 1,041,295. Feeding sheets. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 31, 1964 [March 29, 1963], No. 13161/64. Heading B6B. [Also in Division G5] Apparatus for feeding sheet material, e.g. punched cards or magnetic tape, comprises: feeding means mounted for reciprocation in the direction of feed; clamping means associated with the feeding means and operable to grip the sheet material; and electromagnetic means to reciprocate the feeding means and to actuate the clamping means in a predetermined phase relationship. In a first embodiment, Fig. 1, D.C. energized solenoids 8, 9 co-operate with A.C. energized solenoid 5 to cause arm 2 to oscillate about pivot 1. A further solenoid 15 energized at the same frequency as solenoid 5 co-operates with permanent magnet 19 to periodically clamp and unclamp punched cards 20. The phase of the two signals is adjusted to cause the cards to be fed in one direction or the other. In an alternative form, Fig. 3, A.C. energized solenoids 61, 62 mounted in a movable frame 51 co-operates with a fixed permanent magnet 65 to cause the frame to oscillate, and a further pair of solenoids 69, 70 co-operate with magnet 73 to form the clamp. The arrangement is energized in push-pull with similar arrangements in a second frame 52 so that the cards are given two movements per cycle. The energization circuit, Fig. 4 (not shown), is provided with a switch to de-energize the solenoids of one frame for halfspeed operation and with a reversing switch for reversing the feed. In order to obtain the correct phasing between the clamp signal and the reciprocation signal the frequency of the A.C. signal is arranged to be near the resonant frequency of the oscillating member. The apparatus may form part of a data processing machine incorporating logic circuitry operable to supply the electric signals.

Abstract: <PICT:0737311/IV (c)/1> In a process for dimensionally stabilizing knitted nylon fabric by heat-treating it with hot air and then cooling it, while stretched transversely (see Group VIII), fabric K is carried on a tenter frame E through a casing A where hot air and combustion gas is blown transversely through the travelling fabric by jet members F which extend over the full width of the fabric.  Heat is supplied by a gas burner B providing a flame 41 at the top of a chimney 44, whence hot air and combustion gases are drawn through baffles 59 by fans D which force the gases from an upper chamber 55 through jets F and the fabric K into a lower chamber 49 and thence back to chimney 44.  By suitable baffling in chamber 55, a gradually increasing temperature may be provided from the fabric inlet 16 to the position 56.  Escape of combustion gases into the room is prevented by hoods 71, 72 at the inlet 16 and exit 18 respectively; the hoods may discharge, through ducts 73, 74 into chamber 49 or chimney 44 or create additional draught from burner B.  Water sprays 78 provide initial rapid cooling of the fabric while it is still stretched.  The tenter may increase the stretch on the fabric as it moves from inlet 16 to outlet 18; or it may be set to alternately stretch and slacken the fabric transversely. The carbon dioxide content of the hot gases should lie between 0.5 and 10 per cent; superheated steam up to 30 per cent of the total volume may be included instead of, or in addition to, the carbon dioxide.

Title: Improvements in or relating to aerial bombs
IPC: F42C15/31
Filed: 1943-08-18
Abstract: 583,222. Aerial bombs. VICKERSARMSTRONGS, Ltd., MORPETH, W., and HESELTINE, J. C. W. Aug. 18, 1943, No. 13485. [Class 9 (i)] A delay-action aerial bomb in which detonation of the explosive charge is initiated electrically, has an uncontrolled freely movable make-and-break device so that should the bomb come to rest with the device in the break position, any disturbance of the bomb after the delay period will cause the device to move into the " make " position, thereby completing the firing circuit and detonating the bomb. The bomb has propeller-like vanes 13 normally secured in grooves in the body by a guard ring 10 whose hinged halves are coupled by a pin which is secured to the canister or other holder from which the bomb is released, whereupon torsion springs extend the vanes to horizontal position to steady the fall of the bomb. The opening of the halves of the ring 10 also releases a safety member 9 so that when the bomb makes impact a pin 16 with an insulating section 20 sets forward to complete a circuit energized by a dry battery 7, Fig. 3, to fire an electric match head 23 which ignites a time train 24, Fig. 6, and consumes a pellet 25, thereby allowing a contact 26 to move axially and prepare a further circuit for ignition of an electric match head 30 to detonate the explosive charge subject to the completion of the circuit by the freely-movable make-and-break device 31. This device comprises a planetary roller composed of a metal disc and an insulating disc secured together and gapped at their peripheries so that successive sectors 38a, 38, Fig. 7, of the roller are conducting and non-conducting. The roller turns on a radial spindle 37 and rolls freely between metal plates 32, 33, about a spindle 35. If, upon impact, the bomb comes to rest with the make-and-break device 31 so positioned that electrical connection is established from the battery through the spindle 35 to either of the metal plates 32, 33 in series with the match head 30, the bomb will be detonated immediately on elapse of the delay period determined by the time train 24. If, however, the bomb comes to rest with the roller of the device 31 breaking connection between the battery and the plates 32, 33, the bomb will not be detonated until it is disturbed after the normal delay period, thereby allowing the roller of the make-and-break device to complete the firing circuit.
