Title: Improvements in or relating to devices for dispensing strips of paper or the like
IPC: B41L5/04
Filed: 1938-05-04
Abstract: 514,493. Memorandum appliances. STANDARD REGISTER CO., SHERMAN, J. Q., and GOPPERTON, A. A. May 4, 1938, No. 13339. [Class 16] In autographic registers wherein a paper strip from a roll or pack is reversely folded around the edge of a writing tablet forming the cover and is held against normal tension by spring-pressed balls or detent pins engaging apertures formed at intervals in the length of the strip, the detent means are so positioned that they engage the paper within the receptacle and before the paper reaches the edge around which it is folded. The box 1 houses either one or two stacks of zig-zag folded stationery, such as described in Specification 481,745, which is transversely weakened at the folds and provided with registration perforations, and interleaved with carbons provided with holder strips which are retained in recesses 7. As shown, both the top and bottom of the box may be used as writing platens, and these platens 8 are hinged to the box and provided with spring clamps 15, Fig. 2, for the ends of the record strips. The record strips pass to the platen around a bar 9, and over a bridge plate 10 provided with detent plunger pins 12, the latter being supported on a spring 13 arranged below the plate and adapted to project through holes in the plate to engage the perforations in the stationery to register each form on the platen 8. The pins 12 are rounded so that on extra tension being applied to the record strips, the pins will the depressed to allow further feeding of the strips. The spring clamps 15 carry sup- - porting feet in the form of studs 16 whereby either platen can be used without damaging the record forms on the other. In modifications, the studs 16 extend below the clamp 15 to engage perforations :in -the record forms and platen; or extra spring-pressed pins arranged :beneath the clamp may ,pass through the perforations of the forms o the platen, and also engage perforations on the next forms which are inside the box, in which case the bridge plate 10 and pins 12 are not necessary. Further, the clamp 15 may be dispensed with and detent pins inside the box may engage the forms on the platen and the succeeding forms inside the box. U.S.A. Specification 1,957,034 also is referred to.

Title: Improvements in reinforcing bars
IPC: E04C5/03
Filed: 1946-05-02
Abstract: 611,492. Reinforced concrete. BANNISTER, J. L., and GUEST, KEEN, & NETTLEFOLDS, Ltd. May 2, 1946, No. 13357. [Class 20(iv)] A metal bar for use in reinforcing concrete is of oval cross-section, its periphery being free from projecting corners which may induce local cracking of the concrete, and is twisted throughout its length giving greater adherence with the concrete than that obtainable with a round bar. In the form shown, a steel rod A, hot-rolled to an oval cross-section is cold-worked by applying axial torsion to produce a twist of coarse pitch lying between 8 and 14 times the mean diameter of the rod. The coldworking of the rod raises its yield stress and increases its bond resistance with the concrete.

Title: Improvements in or relating to means for preventing or extinguishing fire
IPC: A62C35/60
Filed: 1930-04-30
Abstract: 352,599. Preventing and extinguishing fires in vehicles. LEADER, S. A., 18, Lonsdale Gardens, Ilford, Essex. April 30, 1930, Nos. 13371 and 14750. [Class 47 (ii).] Means for preventing or extinguishing fires in vehicles by distributing automatically fire-extinguishing medium at danger points in the vehicle, comprises a chamber E, Fig. 1, for the medium, and a chamber F for compressed gas, the chambers communicating by a passage G<2>, E6 which is normally closed by a device E'. The gas moves a piston E<3> to expel the medium by an outlet E<1> normally closed by a frangible diaphragm E<2> The medium may be expelled through a vaporizing or atomizing chamber. The closure device E' is automatically opened electrically in the event of the vehicle being involved in a collision, overturning, or catching fire. It may comprise an electromagnetically-operated valve or a piercer for a compressed gas cartridge, or a fusible or explosive plug adapted to be destroyed electrically. Escape of the gas may be arranged to move a piston to reopen the operating electric circuit. Where a bursting plug M, Fig. 5, is employed, a small auxiliary gas passage M<4> closed by a valve M<5> may be provided. This valve is hand-operated by a flexible cable M<7>, and the small gas pressure in this case expels the medium from the chamber E by a nozzle M<10> adapted to be directed by hand. For closing the electric circuit of the device E<7> at H, H<1>, a pendulum J<6> is adapted normally to hold apart spring contacts J, J<1>, but to allow them to engage in the event of a collision. Other contacts K<2> are adapted to be closed by mercury K<1> in a vessel K in the event of the vehicle overturning. In addition, a thermal switch across terminals is provided in the circuit, and this switch may also be hand-operated. The mercury K<1> may also be arranged to break the ignition circuit of the vehicle. Particularly for aircraft, the release of the medium may be controlled by a piston in a vacuum cylinder, the vacuum at one side of the piston being destroyed electrically to cause movement of the piston to release the medium. In another modification, the medium is expelled from the chamber E by a pump adapted to be operated electrically by any of the devices already described. The passageway G<2>, E<6> may be arranged as a bracket to support the chamber E and other parts. One of the Provisional Specifications describes an arrangement wherein the petrol tank is divided by a partition into a petrol chamber and an upper chamber containing a fire-extinguishing medium. The partition comprises a glass portion adapted to be broken, if the vehicle is suddenly arrested, by an inertia-operated pendulum normally restrained by adjustable springs. The other Provisional Specification describes the provision of a pressure-gas chamber and a medium chamber connected by a passageway closed by a glass partition adapted to be broken by a pendulum.

Abstract: 310,887. Siemens - Schuckertwerke Akt.-Ges. May 2, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Alternating-current commutator and induction machines; commutating windings; exciting.- The commutating pole or compensating windings of a continuous or alternating-current working on a circuit of constant resistance are energized by the potential across the constant resistance circuit or by the energizing potential of the commutator machine whereby the use of large conductors carrying line currents is avoided. Fig. 1 shows the invention applied to a commutator machine 2 cascaded with an asynchronous wattless output machine 1. The compensating winding 4 is in series with the armature winding in the usual way, but the commutating pole windings 3 are star-connected in parallel with the secondary circuit of the main machine 1. Fig. 2 shows a rotor excited commutator machine cascaded with a wattless output machine 1. The compensating winding 7 in this case is connected in parallel with the secondary circuit of the main machine. The winding 7 may be so dimensioned and adjusted in phase that its current has a. component which produces the energizing field of the machine whereby the regulating transformer 6 is relieved of part of the exciting current. The resistance 8 serves for the regulation of the compensating action. The invention is also applicable to commutating machines connected in the secondary circuit of asynchronous machines having outputs independent of slip. In this case, the commutator machine introduces into the secondary of the main machine two potentials one of which increases proportionately to the slip while the second is independent of the slip. This second potential works on a circuit of constant resistance and may energize the commutating pole windings. If, as in the case of the energizing windings of synchronous machines or asynchronous wattless output machines, the resistance varies with temperature, a correspondingly variable resistance may be connected in the circuit of the commutating pole or compensating windings. Commutating pole or compensating windings may be connected partly in series and partly in shunt.
