Title: A valve for controlling air flow
IPC: A62B13/00
Filed: 1963-03-19
Abstract: 956,435. Valves. EWERS & MIESNER HARTGUSSWERK UND MASCHINENFABRIK G.m.b.H. March 19, 1963 [June 19, 1962], No. 10920/63. Addition to 925,436. Heading F2V. A valve controling the flow of air through a supply or discharge pipe of shelter comprises a housing 1 having valve seats 10 arranged at right angles to each other. A lever arm 7, pivoted about an axis 6, carries valve closures 8, 9 for co-operation with the seats and the arm is provided with a notch 62 which is normally engaged by a spring-loaded pin to hold both valves open when air passes normally through the housing. In the event of an explosion, the pressure wave P acting on the valve 8 causes the lever to rotate, overcoming the pin, action, to close the valve 9. Two notches 63a, 63b are also provided which are engaged by the pin in either valve closed positions, the notches being such that once engaged, forces acting on the valves cannot rotate the lever. The pin is releasable from outside. Manual closing of the valves is provided by a lever 70 which on rotation actuates the lever and looks the valve in a closed position by engagement with a detent 73. The centre of gravity S of the lever assembly is located on opposite sides of the seats from planes containing the shaft axis and parallel to seats. Each valve closure is pivoted to the lever arm and loaded by a spring 60.

Title: Integrating circuit
IPC: G06G7/186
Filed: 1972-03-10
Abstract: 1331205 Integrator circuits, waveform generation TEKTRONIX Inc 10 March 1972 [17 March 1971] 11257/72 Heading H3T In an integrator for repetitive signals, means responsive to the difference between the integral at the end of the integration period and the axis of integration causes the integral at the end of the next signal to be the same as at the beginning. As shown, a sawtooth wave 50 is integrated to produce the parabollic wave 66 which is again integrated to produce the S shape wave 54, these being suitable for television display connection. At the end of each wave a pulse 24 causes diode 20 and 22 to become conductive to short-circuit the integrating capacitor 12. If any discharge occurs a pulse is produced by transistors 40 and 44 which is rectified and stored in a capacitor 36. This provides a constant current through resistor 34 to so move the integral as to cause the integral of the next wave to start and end at the same value. Current through a resistor 38 biases the integrator towards a valve which allows the diodes to conduct. In Fig. 4, not shown, two connection circuits are provided, one for each polarity of input signal.

Abstract: 529,242. Polycarboxylic acids; synthetic resins. ARMOUR & CO. April 14, 1939, No. 11359. Convention date, May 27, 1938. [Class 2 (iii)] Aliphatic polycarboxylic acids are made by hydrolyzing the polynitriles obtained by polymerizing aliphatic nitriles, containing at least ten carbon atoms in the molecule; under the influence of heat and in the presence or absence of one of the following catalysts: aluminium chloride, bromide, fluoride or sulphide ; zinc chloride or bromide ; stannic chloride ; titanium tetrachloride, phosphorus trichloride, boron trichloride or tribromide, sodium, phosphorus or sulphur. The hydrolysis of the polynitriles may be effected by treatment with steam in the presence of aqueous alkali solution, and acidifying the products. In examples (1) olenitrile is polymerized with the aid of aluminium chloride or phosphorus and the products hydrolyzed, (2) the nitriles from linseed oil fatty acids are polymerized by heating in an atmosphere of nitrogen without a catalyst and the product hydrolyzed, (3) a mixture of palmito- and stearo-nitriles is polymerized with the aid of aluminium chloride and the product hydrolyzed, and (4) the nitrile from cotton seed oil fatty acids are polymerized with the aid of aluminium sulphide and the product hydrolyzed. The polycarboxylic acids can be condensed with polyhydroxy alcohols, e.g. glycerol, to give synthetic resins.

Scrap, consolidating; shearing. - Scrap metal from turning, boring, planing, and other machines is compressed by rollers which feed the strip to reciprocating cutters. The scrap is placed in a hopper 4 with travelling bands 12a which feed it to fluted rollers 9, Fig. 3, mounted on levers 6. The rollers are driven from a pulley 22, Fig. 1, through spur and bevel gear 20a, Fig. 3, and 18, Fig. 1, worm gear 15, and spur gear 27. The levers 6 are pressed together by springs 8 on rods 7, the pivots of the levers being the shafts 5a of the lowest rollers which are adjusted by wedges 29 and adapted to move apart, against the action of springs 11, if an incompressible piece is fed. The compressed scrap passes through a funnel 23, Fig. 3, adjustable by screws 24 and is cut into long or short portions, to be fed to a briquetting-machine, by knives 28 reciprocated by an eccentric 26. The levers 6 have faces between the rollers to guide the scrap, and grooves to hold side plates 10, Fig. 4, for the same purpose. The bands 12a are driven through chain-gearing 16<f>, 16g, Fig. 1, and the worms 15 are feathered on the shaft 16 so that they can move horizontally with the shafts 5<a> by means of arms.

Patent GB-601387-A (GB)
Title: Improvements in or relating to counting apparatus
IPC: H03K23/82
Filed: 1945-05-07
Abstract: 601,387. Pulse-counting circuits. NATIONAL CASH REGISTER CO. May 7, 1945, No. 11665. Convention date, Jan. 27, 1944. [Class 40 (vi)] [Also in Group XIX] The invention relates to counters of the kind comprising a plurality of gas-filled electric-discharge tubes 1, 2 ... 9, 0, each representing one digit of a denomination, the tubes being arranged to be fired (i.e. become conducting) one at a time in endless chain sequence in response to impulses impressed on all the tubes, the cathodes being so connected electrostatically that a tube, when fired, will extinguish its predecessor. According to the invention, the anode of each tube is connected to the source of supply potential through a resistance shunted by a capacity, thus enabling the fall in anode potential occurring when the tube is fired to be utilized to generate a transfer impulse. When any tube fires, the resulting current now through a cathode resistance 27 causes a potential rise at a point 26 connected to the grid of the next higher tube, this latter tube thus being primed so that it alone of the rings of tubes is fired upon the arrival of the next impulse on a common line 33 connected to all the grids. The anode of each tube is connected to a common potential source 20 by a resistance 21 shunted by a condenser 22. When a tube fires, the action of the condenser causes a high momentary rise in cathode potential, this rise being transmitted through a condenser 29 to the cathode of the preceding tube, to extinguish this tube. The potential drop across any anode resistance 21 can be used to generate a transfer impulse by connecting a condenser 22 to the anode circuit as shown. The phase of the impulse (which is negative) may be reversed by passing it to the grid of a normally-conducting vacuum tube 43, the potential rise on an anode resistance 44 when conduction ceases upon the arrival of the negative impulse at the grid causing a positive impulse at a point 45. Specifications 592,174, 592,793 and 593,682 are referred to.
