Filed: 1958-08-15
Abstract: 847,743. Blasting and like fuzes. IMPERIAL CHEMICAL INDUSTRIES Ltd. May 29, 1959 [Aug. 15, 1958], No. 26314/58. Addition to 746,843. Drawings to Specification. Classes 9(1) and 9(2). Relates to an improvement of the flexible cord-like ignition device claimed in the parent Specification and comprises a metal wire coated with a non-detonating fast burning deflagrating composition containing solid oxidising and reducing agents, this core being surrounded by a flexible, incendiary waterproof envelope and a gas-permeable space being provided between the coated wire and the envelope. The envelope is made of a non-detonating deflagrating composition of low gas evolution characteristics and high heat emissivity and comprising a mixture of oxidising and reducing agents bound together by a non-detonating combustible agent. In an example a copper wire is coated by passage through a slurry consisting of nitrocellulose plasticized with dibutyl phthalate, lead dioxide and silicon, the composition being diluted with acetone. The coated wire is dried in air before countering with three flat cotton ribbons and subsequent passage through an extrusion die in which the waterproof envelope is applied. A composition consisting of red lead, potassium nitrate, silicon, diethyldiphenyl urea and nitrocellulose plasticized with dibutyl phthalate is used for the envelope.

Title: Method and apparatus for the continuous vaporization of volatile substances
IPC: A01M1/20
Filed: 1953-09-25
Abstract: In a method for the continuous vaporization of volatile substances, a solution of one or more such substances in one or more volatile organic solvents, at least one of which is capable of catalytic exothermic autoxidation e.g. petrol, ethanol, methanol, acetone and benzene is fed continuously to a pre-heated oxidation catalyst e.g. one or more of platinum, silver, copper and vanadium or oxides thereof and the substance there vaporized by the heat liberated by the exothermic autoxidation.  The solutions may be fed continuously from a container packed with cotton wool or the like by capillary action to the catalyst, which may be thinly coated on an inert carrier of large surface area such as asbestos wool, glass wool, or copper wire gauze housed in the cap of the container and formed of two sides of wire gauze through one of which the solution is fed and the vaporized substance being defused into the atmosphere through the other.

Filed: 1936-09-30
Abstract: 484,204. Printing-machines. EGLI, A. A. Sept. 30, 1936, No. 26576. Convention date, Aug. 21. [Class 100 (ii)] Stopping - arrangements.-In a multi-colour intaglio printing-machine in which a number of printing-cylinders coact with one impression cylinder, a tripping device is provided which trips each printing-cylinder if a sheet is missing when the grippers which normally would grip such a sheet pass the printing-cylinder. The grippers 2, Fig. I, of an impression cylinder P are formed of two forked parts 2a, 2b, Fig. IV, and a feeler 5 is arranged between the forked parts and above a recess 4a formed in the gripper support 4. The feeler 5 is pivoted at 6 to the gripper 2 and is formed with a fork 7 engaged by a pin 8 on a sleeve which is fitted with a locking lever 9 and is formed with a recess engaged by a spring pawl 11 on an oscillating lever 12. If a sheet is held by the grippers, the movement of the feeler 5 is limited and the pawl 11 moves past its co-operating recess and fails to move the lever 9 into its locking position in which it engages the nose 12a of the lever 12 and limits the extent of oscillation of this lever. With the lever 12 is associated a lever 14 fitted with a roller 15 which is moved by the cylinder P past a series of levers 19, Fig. IX. When the movement of the lever 12 is not limited it permits the roller 15 to pass under the levers 19 without moving them, but if a sheet is not present the roller 15 acts on the levers 19 and the movement of each lever 19 is transmitted by linkage 21 to a lever 22 fitted with a cam curve which controls the position of an oscillating pawl 25 which is thus made to throw the printing-roller out of operative position. As shown in Fig. IX three sets of levers 19 are used for controlling three different printing- cylinders which are mounted in pivoted frames.

Abstract: 1,081,126. Hydraulic rams. HUCK MANUFACTURING CO. June 24, 1965 [July 9, 19641, No. 26902/65. Heading F1P. A hydraulic ram comprises a piston 78 reciprocable in a cylinder in which is fixed a tube 108 extending parallel to the cylinder axis and passing through a bore in the piston. This tube conveys fluid from an inlet passage 104 to the other side of the piston, and at its ends its outer surface is relieved to allow leakage from one side of the piston to the other so that the force exerted by the piston is reduced at the end of its stroke. The cylinder is connected in series with an intensifier (22) Fig. 1 (not shown) and through a changeover valve (16) to a source of pressure (10). The leakage past the piston 78 also allows fluid flow to continue when the piston has reached the end of its stroke, thus enabling the intensifier to complete its stroke. The piston is connected to spring-loaded collets 136 which act to draw fasteners intn a tubular anvil 58.

Title: Improvements in or relating to trigger and counter circuits
IPC: H03K3/286
Filed: 1952-10-29
Abstract: 740,367. Transistor multi-stable state circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 29, 1952 [Dec. 31, 1951], No. 27177/52. Class 40 (6). A trigger circuit having two stable states comprises a transistor having a resistor providing positive feed-back connected in its base circuit and a thermionic valve having its anode cathode path connected in series in the emitter circuit of the transistor. In the circuit shown in Fig. 2, the transistor is composed of N-type material and a variable tapping on the resistor 12 in the base circuit. of the transistor is connected to the control grid of the valve 16. In one condition of the circuit both transistor and valve are conducting while in the other condition both are non-conducting and it is stated that by the application of suitable pulses to a point in the circuit, e.g. the point M, the circuit can be switched from one condition to the other. By a suitable choice of circuit component values, triggering may be effected by either alternate positive and negative pulses or by pulses of one polarity only. In Fig. 1 (not shown) a transistor of P-type material is used, the anode of the valve being connected through a battery to the emitter electrode. In a further circuit, Fig. 3, the grid of the valve is connected to a tapping point on the collector bias battery and the potentiometer in the base circuit is replaced by a simple resistor. Fig. 12 shows a counter circuit employing the circuit of Fig. 2. The circuit is triggered by a series of positive pulses applied at A, and develops a rectangular waveform across a load resistor in the anode circuit of the first stage 70. This waveform is differentiated by the condenser 30<SP>1</SP>, the resulting pulse waveform being employed to trigger the second stage 72. In Fig. 13 is shown a counter-circuit in which a rectangular input waveform is employed, the waveform being differentiated and limited by condenser-rectifier combinations so that trains of positive pulses are applied simultaneously to the emitter and collector electrodes of the first transistor. The output waveform from each stage is taken from across a resistor in the collector circuit of the transistor. Fig. 8 (not shown) shows a four-stage binary counter similar to that of Fig. 13 but wherein the outputs are taken from resistors in the anode circuits of the valves and Fig. 10 (not shown) shows a circuit similar to that of Fig. 12 but wherein the differentiating circuit is followed immediately by a valve amplifier and cathode follower.
