Filed: 1934-11-05
Abstract: 448,427. Sporting-guns. BRETTON, G., 1, Cours Fauriel, St. Etienne, Loire, France. Nov. 5, 1934, No. 31774. [A Specification was laid open to inspection under Sect. 91 of the Acts, May 6, 1935.] [Class 119] Relates to sporting guns of the single or multi - barrel type having a hinged breechblock, According to the in vention, the pivot pin 7, Figs. 1 and.6, on the breech-block 5 is slidably mounted in longitudinal slots 8 in the breech casing 1, a handle 6 is rotatable on the pivot pin and is formed with a cam face 9 adapted to co-operate with a seat 10 on the breech casing, a spring catch 26 is provided on the handle to engage and disengage a notch 27 in the breech-block at the required moments, and a cam disc 22 is attached to the breeck-block to co-operate with a pin 25 on the breech casing, the arrangement being such that when the handle is lifted and swung back from the closed position, Fig. 6, the cam face 9 leaves the seat 10 and the spring catch 26 engages the notch 27, then the breechblock is slid back while the pin 25 is in the radial groove 24 of the cam 22 and until the pin reaches the circular groove 23. After this, the breech-block is swung up while the pin 25 rides in the circular groove 23. During this opening movement, a pin 17, on a. link 16 carried by the breech-block, pulls on a nose 15 on an extractor 13 and then slips off into an inclined slot 18 in the breech casing. The cartridges are thus withdrawn from superimposed barrels 3, 4, Fig. 2, and the extractor then returned forward by a spring 12. A spring brake 20 is provided to keep the open breech-block in position. The knob 39 of the handle is formed with a notch acting as a back-sight. The Specification as open to inspection under Sect. 91 describes also a transversely slidable safety bolt for locking the trigger springs and tumbler connections of the firing mechanism, and a modified breech mechanism in which the breech-block does not swing up but merely slides back with the handle to open the breech. This subject-matter does not appear in the Specification as accepted.

Abstract: 410,842. Electric supply systems. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Arkenburgh, W. H. ; 1135, Parkwood Boulevard, Schenectady, New York, U.S.A.) Nov. 14, 1932, No. 32188. Convention date, Nov. 13, 1931. [Class 38 (iv).] Regulation, automatic systems for ; systems depending on the use of two or more sources ; equalizing load on generator.-Electrical energy is supplied to a variable load from two or more sources in parallel under the control of a saturable reactor having an alternating current winding connected to control the output of one supply circuit and a direct current saturating winding responsive to the current in another supply circuit. In one arrangement, Fig. 1, a main source 1 of any periodic potential with a direct current component is capable of supplying all the current required by a load 2 while maintaining also, through a rectifier 4, e.g. of the full wave copper oxide type, a substantially constant voltage across the terminals of a direct current auxiliary stand-by source 3 which is preferably, as shown, a storage battery, but may be a direct current generator, a primary battery or an alternating current and rectifier combination. The circuit of the load 2 includes a saturating winding 7 of a reactor 5 of which the variable reactance alternating current winding 6 is in circuit with the source 1. When the load requires little or no current the reactance of the winding 6 is preferably such that a very small charge is put into the battery 3, but when the load requires more current the winding 7 saturates the reactor 5, decreasing the reactance of the winding 6 and maintaining the voltage across the battery 3 substantially constant. The increased load current is thus taken from the source 1 and the battery 3 is maintained fully charged for service should the source 1 fail. When the source 3 is a direct current generator or a primary battery the voltages are so adjusted that no current is supplied to it under normal conditions. Fig. 2 shows a similar arrangement with a reactor 13 such that the direct current generator 12 supplies all the requirements of load 11 up to a predetermined value, whereafter the alternating current source 8 supplied any additional requirements. Up to the predetermined value of the load current the reactance of the winding 14 is high and little or no current is supplied by the source 8. With a higher load current the reactance of the winding 14 is reduced and more current is supplied by the source 8. In a modification of this arrangement the generator 12 is replaced by an alternating current source connected through a rectifier. Reference has been directed by the Comptroller to Specifications 13656/13, [Class 38 (ii)], 377,671, and 383,132.

Abstract: 410,777. Altering physical or molecular structure by mechanical treatment. ALLGEMEINE ELEKTRICITATS-GES., 2, Friedrich Karl-Ufer, Berlin. Nov. 14, 1932, Nos. 32219 and 32220. Convention dates, Nov. 12,1931 and Aug. 16,1932. Addition to 363,697. [Class 83 (iv).] Ribbon of ferromagnetic material for loading cores, Krarup windings, and for use in other weak magnetic fields according to the parent Specification, is subjected to plastic deformation in order to reduce elastic stresses. The ribbon may be creased at regular intervals to form a polygonal core, the corners being rounded off to prevent stray fields thereat. An annular core may be formed by winding the ribbon on a pin of small diameter compared with that of the finished core, the ribbon retaining the desired curvature. The ribbon may be deformed in alternate directions, and in Fig. 3, it passes between rows of staggered rollers 6, 7 for this purpose, the ribbon being also curved permanently in the direction in which it is wound as a core. The tensile stress on drawing off or winding the ribbon is also a factor determining the deformation. After deformation, tempering at 100 to 350‹ C. may be effected. With the apparatus of Fig. 3 a de-burring operation is performed. Insulation may be effected by a paper strip, or by soaking the ribbon, before or after winding, in an insulating solution such as a varnish, or in water glass, or by chemically affecting the surface of the ribbon.

Title: Improvements in or relating to monostable circuits
IPC: H03K17/58
Filed: 1960-09-20
Abstract: 953,176. Tunnel diode monostable circuits; controlled non-linear inductors. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 20, 1960 [Dec. 30, 1959], No. 32265/60. Headings H3B and H3T. A monostable circuit comprises a magnet core having one winding in series with a bias source, an input pulse source and a tunnel diode and a second winding connected in series with a bias source, the arrangement being such that normally the current through one winding establishes flux saturation of the core in one sense and upon the occurrence of a pulse in the input winding the condition of the tunnel diode is switched whereby flux saturation is temporarily established in the other sense. Fig. 3 shows an arrangement comprising a saturable core 1, a bias winding 4 in series with a bias current source 12, 13 and a second winding 2 connected in series with an input transformer 9, a tunnel diode 7 and bias source 5 and 6. In the normal condition, the tunnel diode operates in a region before the peak of its current voltage characteristic where the current through it is sufficiently high to saturate the core. An input pulse in winding 9 temporarily shifts the operating point of the diode to the region of the " valley " point where the current is so reduced that the bias current in winding 4 saturates the core in the opposite sense. Thereafter, the circuit returns to its initial condition so that a pulse is produced in output winding 3. The core may be of a square-loop type and a further tunnel diode may be connected in series with winding 4 (Fig. 4, not shown) in which case the diode 7 may be operated in the " valley " region and the additional diode on the slope up to the peak point. It is also stated that the circuit of Fig. 3 could be operated around the valley region instead of round the peak region. If two input windings are connected in series an " OR " or " AND " circuit may be provided, the latter relying on the threshold of the tunnel diode or a square loop core. In addition, if one input winding carries reference pulses a " NOT " circuit may be provided, an output being produced by the reference pulses only when they are not opposed by an input pulse.
