Title: Improvements in and relating to percussion fuzes, particularly to those for shells of small calibre
IPC: F42C15/22
Filed: 1938-07-08
Abstract: 516,035. Projectile fuzes. BIRKIGT, M. July 8, 1938, No. 20297. Convention date, Jan. 21. [Class 9 (i)] Relates to a directaction percussion fuze of the type in which the firing pin is temporarily locked in inoperative position by at least one locking pin adapted to be driven out of locking position into a housing, so as to release the firing pin, under the effect of the centrifugal force due to the rotation of the projectile about its axis. According to the invention, the locking pin or pins is or are carried by an axially displaceable holder which, before the discharge of the projectile, is held by a further locking member, releasable solely by the action of centrifugal force, in a rest position in which the locking pin or pins is or are displaced in relation to a cavity or cavities located in the body of the fuze, whilst the holder is, after discharge of the projectile and after release of the further locking member, moved into d position in which the locking pin or pins can be displaced into the cavity or cavities under the action of centrifugal force. As shown, the fuze comprises a body 1 on which is screwed a cap 2, the front of the fuze being closed by a thin sheet or disc 7 clamped between the body and the cap. The striker 8 which is normally maintained in inactive position by locking pins 9, is mounted together with the pins in an axially displaceable holder 12 adapted to be retained in its rest position by a split ring 13 releasable solely by the action of centrifugal force and interposed between the body 1 and a flange 12<1> on the base of the holder. In the position of rest of the holder, the conical ends of the pins 9 are, as shown slightly out of register with cavities 10 formed in the body 1 and cap 2. In operation, upon discharge of the projectile, the ring 13 opens out under the action of centrifugal force and releases the holder 12, which, after a time, moves forwards assisted by the action of the coned ends of the pins 9 on the edges of the cavities 10, so as to bring these pins into complete alignment with the cavities. The pins are thereupon displaced into the cavities under the action of centrifugal force and the striker is free to be driven in on impact.

Title: Electrical switching arrangements for assigning prices in  automatic vending machines
IPC: G07F5/22
Filed: 1971-04-19
Abstract: 1344364 Assigning prices; indicating ticket prices F BREDE 19 April 1971 [30 Jan 1970] 20553/71 Headings G4V and G4T An electrical switching arrangement for assigning prices in automatic vending machines comprises two sets (1-M), (1-N) of independently selectable switches, a correlator IM which is permanently programmed to correlate individual prices with predetermined pairs of switches, one switch being from each set, an addressing circuit ABR, ABL for applying signals from a selected pair of switches to said correlator, and an output circuit TS-AL inductively coupled to said correlator for extracting from said correlator an output signal representing the price corresponding to the selected pair of switches. As described for a ticket printer, sets of selection buttons (1-M), (1-N) corresponding to ticket type (return, weekly &c.) and destination respectively, are connected through resistors WR-M, WL-N to the bases of transistors TR-M, TL-N. The sets of buttons are arranged in a matrix with their transistors interconnected by price wires PSD forming the correlator, in such a manner that depression of one button from each set applies a pulse from a current source SQ to the wire PSD appropriate to the price concerned. Prices.-Each price comprises three decimal digits, and is stored in binary-coded-decimal form, there being four bits per decimal digit. The bits are represented by twelve (3 x 4) ferrite cores FK-AL each feeding an associated amplifier gate circuit TS-AL. The amplifier output leads AL are grouped in three sets of four for representing the three decimal price digits. Each amplifier TS-AL includes an AND gate, to prevent spurious pulses from reaching the outputs AL. Each price wire PSD passes either through or around successive cores FK-AL, representing respectively a binary "1" or "0". When a pulse passes along a price wire, those ferrite cores FK-AL with which the wire is coupled transmit the pulse to their associated amplifiers TS-AL, so that a series of "1"s and "0"s appear at the output leads AL to indicate the price. The pulses are fed to a counting chain or intermediate memory. As an example, the wire PSD-11 couples with five ferrite cores, and when pulsed, the number 1000, 0101, 1001 (85À9) appears on the output leads AL. Two additional ferrite cores FK-(RL, AFL) and amplifiers TS- (RL, AFL) are provided for indicating when certain tickets are not available. The first set of selection buttons (1-M) may alternatively represent commodities such as sugar, flour or cigarettes, and the second set (1-N) represent quantity such as pounds, kilos, packets; plugin conductor plates may be employed.

Filed: 1960-06-13
Abstract: Fe, Co, Ni, Cu, Mo, W, Re and alloys of these metals with each other and with other metals having an oxide which is stable up to 300 DEG C. and has a free energy of formation at 27 DEG  C. in the range 30-70 kilocalories per gm.-atom of oxygen, e.g. Cd, Tl, Ge, Sn, Pb, Sb, Bi, In, have their elevated temperature properties improved by first forming a particulate dispersion, the metallic particles having uniformly dispersed therein submicron sized particles of one or more refractory metal oxides and subsequently compacting by conventional means.  The refractory oxides are those having a free energy of formation at 1000 DEG  C. above 60 kilocalories per gm.-atom of oxygen and their average particle size is in the range 5-1000 millimicrons.  Suitable oxides are those of Y, Ca, La, Be, Th, Mg, V, Hf, Ce, Al, Zr, Ba, Ti, Si, Ta, V, Nb, Cr, while mixed oxides such as Mg Al2O4, aluminates, silicates, titanates and complex silicates such as sodium aluminium silicate, may also be employed.  The dispersion has a surface area of less than 10 square metres per gram, and the average size of the grains of metal is less than 10 microns. Ratio of oxide: metal may be as high as 1 : 1 by volume, but are generally 0.05-30% of oxide by volume.  The composition is made by bringing oxygen-containing compounds of the metal or metals to be improved into intimate contact with discrete particles of either the desired refractory oxide(s) or a compound which on heating to constant weight at 1500 DEG  C. is converted thereto, decomposing said compound if necessary, reducing the oxygen-containing compound to metal at a temperature below the sintering temperature of the metal, and subsequently sintering the reduced product below its melting point until its surface area is less than 10 sq. m. per gm.  The oxygen-containing compound of the metal or metals may be precipitated from a soluble salt by addition of an alkaline solution on the refractory oxide which may be in the form of an aquasol, followed by washing, drying and reduction in a stream of reducing gas. Alternatively an oxygen-containing compound of the metal(s) to be improved and an oxygen-containing compound of the refractory metal whose oxide is to be dispersed therein are fused together in air to decompose the compounds to oxides, quenching the melt, finely dividing the mass and reducing as before.
