Patent GB-1514139-A (GB)
Title: Fire arms
IPC: F41A19/06
Filed: 1976-03-25
Abstract: 1514139 Firing mechanism for peripherally primed projectile C BRUNO and B PAOLO 25 March 1976 [14 April 1975] 11972/76 Heading F3C A radial percussion arrangement for peripherally primed self-propelling ammunition includes a firing pin located in an inclined bore in the upper part of the breech and in communication with the firing chamber. The angle of inclination is such that the tip of the pin is turned towards the breech face. Thus as the projectile begins to move it cams the pin back up the bore and scoring of the projectile by the pin is diminished. Scoring is additionally diminished by locating the pin loosely in the bore and without recoil means, by providing a passage to direct gas from the detonation on to the tip of the pin, and by providing a light hammer biased permanently away from the pin. In the preferred embodiment, a bolt 8 is reciprocated to produce automatic fire by the force of the gases of detonation and a recoil spring 10. The bolt carries a locking rod 7 which during the forward stroke of the bolt pushes a projectile 5 from the magazine 6 into the firing chamber 4 of the breech 22 and which during the initial part of the return stroke acts to close the firing chamber to prevent the backward escape of the gases of detonation. A firing pin 20 is loosely located in a rearwardly inclined bore in the breech and is struck by a light hammer 19 pivotally mounted upon the receiver 2. The hammer is permanently biased away from the pin by a leaf spring 18 which engages a roller 16 mounted upon the rear arm of the hammer. To move the hammer into firing contact with the pin the bolt is provided with a flat spring 12 having an upturned forward end. In operation, as the bolt moves forward, at a point where it is slightly spaced from the breech face (see Fig. 2) the flat spring 12 engages the roller 16 against the action of leaf spring 18. The relative strengths of the springs is such that as the bolt hits the breech face so the spring 12 overcomes spring 18 to project the hammer on to the pin (see Fig. 3) and cause the pin to detonate the projectile and the hammer to bounce back off the pin aided by the spring 18. Consequently upon movement of the projectile the pin is free to be carried back up the bore. A passage 3 connecting the bore with the firing chamber is provided to assist movement of the pin up the bore.

Abstract: 615,612. Fluid-actuated valves. TELEFONAKTIEBOLAGET L. M. ERICSSON. Sept. 18, 1941, No. 12002. Convention date, Feb. 13, 1940. [Class 135] A valve, e.g. for controlling the flow of compressed air from an inlet 1, Fig. 1, having a fixed plug 3, to an outlet 5, includes a diaphragm 6 having a port 7 controlled by a relief valve 9. As shown, air flows through the port 7 to the space above the diaphragm until the pressure therein reaches a predetermined value at which the diaphragm flexes and closes the mouth of the inlet 1. In this position, the edge of the diaphragm around the port 7 curls upwards to permit a slight leakage of air through the port to hold the diaphragm in its flexed position. In a modification, the plug 3, Fig. 3, is mounted on the stem of the valve 9. A spring-loaded diaphragm may be substituted for the diaphragm. The Specification as open to inspection under Sect. 91 comprises also an arrangement in which communication between the space above the diaphragm and the inlet is effected through a port formed between an edge portion of the diaphragm and an internal adjacent wall of the space beneath the diaphragm. This subject-matter does not appear in the Specification as accepted.

Abstract: 531,247. Thermionic valves. LELAND STANFORD JUNIOR UNIVERSITY, BOARD OF TRUSTEES OF. April 27, 1939, No. 12636. Convention date, May 24, 1938. [Class 39 (i)] In a high frequency valve active grid loss is prevented by using a pair of spaced grid sections 2, 15, the section 15 nearer the anode 3 being spaced from the cathode a distance approximately equal to the travel of an electron during threequarters of a cycle ; the section 2 is spaced from the cathode at such a distance that at least as much or more energy is transferred from the electrons to the grid sections during travel from the sections to the anode as is given to the electrons during their travel from the cathode to the sections. The two grids are coupled by the condenser 17, 18 and the section 15 is at a higher d.c. potential than the section 2 and is positive with respect to the cathode ; a choke 16 is included in the circuit to the section 2. A.c. is imposed from the source 14 and the coil 11 is coupled to the circuit 9, 10 for feed back. If more energy is given by the electrons to the grid sections than is received by the electrons the valve will self oscillate without the necessity of external feed back. A suppressor grid may surround the anode. In a modification the grids 2, 15, Fig. 5, are connected together and a third grid 35 is placed between them and maintained at a higher positive potential. In another form two grids 2, 15, Fig. 4, connected together are used in a hollow resonator containing standing waves. The resonator comprises two separated sections 23, 24 capacity coupled by the flanges 28, 29; the emitter is formed on a face 21 independently heated. The grids are excited from a loop 26 within the resonator and a grid leak 27 is connected to the section 24. Energy is removed by a loop 32. A mathematical exposition and an explanation of the grid action is given in the Specification.

Abstract: The combustion of sulphur, which is introduced together with a combustion supporting gas into a closed chamber, is effected under conditions adapted to produce high pressures such as are produced in the cylinders of internal-combustion engines.  Conditions characteristic of an explosion result when the sulphur is admitted into the chamber in such a manner, for example in the form of vapour or as a jet of liquid or powdered sulphur, that it is rapidly disseminated through the combustion-supporting gas. The energy which is developed may be utilized as power by effecting the combustion in the cylinder of an internal-combustion engine operating on a normal cycle.  By rapidly cooling the products of combustion by causing them to expand adiabatically, sulphur trioxide is produced.

Title: Improvements in or relating to work centering devices
IPC: B23Q35/04
Filed: 1924-05-24
Abstract: 216,530. British United Shoe Machinery Co., Ltd., (Assignees of Fagus Werk K. Benscheidt, and Black, C.). May 24, 1923, [Convention date]. Turning.-In a device for centring work suchas rough last blocks in a copying-lathe, a model is employed in conjunction with positioning and marking devices in such a way that centres are marked on the blank which define an axis of rotation having the same geometrical relation to the blank as the corresponding axis of rotation has in the model. This enables a blank to be converted into a finished last with a minimum waste of material. In the diagrammatic Fig. 1, two horizontally-guided blocks 12 traversed by a right and left hand screw 14 are provided with pivots 16 for bell-crank levers 18, 20, whose horizontal arms are slotted at 22 to receive a pin 26 mounted on a sliding rod 28 which is normally pulled upwards to maintain the slotted portions 22 in a horizontal position by a spring 34. The vertical arms of the bell-cranks carry feelers 40 and are slotted to engage pins on sliding rods 37. The marker indicated at 42 is interconnected with the rod 28 in such a way that if the marker is displaced by a a distance x from a central axis MM. the rod 28 with its guides is moved a similar distance in the opposite direction. In operation, the slots 22 are first put in a horizontal position and the blocks 12 are traversed until the feeders 40 engage the model. The marker 42 is then moved to coincide with the axis of rotation of the model. The retaining pin 36 is now removed and the blank positioned between the feelers, the bar 28 being pulled down by a lever 46 until the feelers engage the blank. The feelers are now in some such position as de and the blank is marked by the marker 42. It is shown from the geometry of the figure that ae/ad = ac/ab so ad ab that the marker divides the corresponding dimensions of model and blank in the same ratio irrespective of the size of the blank. In the embodiment shown in Figs. 2 and 4, two sets of' positioning devices are employed to position two perpendicular axes in the work piece, the second set being indicated by the same references with the additional index a. The rear portion of the last block is supported in a spring fork. The centre punches 50, 52 are moved horizontally by means of screws 74, 75 operated from a shaft 76, and equal opposite movement is given to the guides of the rod 28 by means of sprocket and chain gearing 84 and shaft 86. The vertical movements of the centre punches are effected from a hand-wheel 58 through shaft 63 and vertical shafts 54, 56, equal opposite movement being im. parted to the guides of the rod 28a by means of bevel gears 64, telescopic shaft 66 and vertical shaft 70.
