Title: Improvements in chemical fire extinguishers
IPC: A62C13/00
Filed: 1942-02-16
Abstract: 552,626. Fire-extinguishers. MATHER & PLATT, Ltd., and MARSLAND, S. W. Feb. 16, 1942, No. 2060. [Class 47 (ii)] In a chemical fire-extinguisher, the cap a upon the holder b for the acid container c is formed with a chamber d to accommodate a packing ring e which has a sliding frictional fit on the usual operating spindle f. A cap g upon the chamber d provides an upper guide for the spindle. Normally, the packing ring is in its lower position as shown, providing a vent to the atmosphere from the interior of the extinguisher via clearance passages h, i, but when the spindle is operated to fracture the acid container c, the gas pressure generated carries the spindle outwards and lifts the ring e to its upper position to make a sealing joint with the cap g, and so close the clearance passage i.

Abstract: Diamond crystals are prepared by heating carbonaceous material at a temperature of at least 1200 DEG  C. and under a pressure of at least 50,000 atmospheres in the presence of a catalyst that consists of niobium carbide and one or more of copper silver or gold.  The carbonaceous material may be graphite, amorphous carbon, coal, coke, charcoal, or sugar charcoal containing carbon as its major component, or organic compounds containing a number of carbon atoms, such as coal tar, pitch, wood, paper, naphthalene, wax or paraffin.  The catalyst may be in the form of an alloy or another form of mixture and, in addition to the metals listed above, aluminium and tin may be used, and also instead of copper, silver and gold, compounds of these elements such as cuprous oxide, silver oxide or sulphides may be used.  An apparatus of known type (as disclosed by H. Tracy Hall, pg, 125/131 , "The Review of Scientific Instruments" Vol. 31, No. 2 (1960)) was employed to expose the reaction vessels (Figs. 2 and 3, not shown) to the high pressures and temperatures necessary to the reaction.

Filed: 1949-01-31
Abstract: 657,267. Peak voltage measurements. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Jan. 31, 1949, No. 2677. [Class 37] A circuit arrangement for the measurement of the peak amplitude of recurrent pulses of short duration comprises a capacitor adapted to be charged through a rectifier by the pulses to be measured, the rectifier being arranged in the output of a high gain feedback amplifier to the input of which the pulses are applied, the feedback connection being so made that the output impedance of the amplifier (i.e. the effective charging impedance of the capacitor) is less than it would be without feedback, and that the feedback path is operative both when the rectifier is conductive and when it is non- conductive. A high gain amplifier A has the pulse waveform E applied to its input via resistor R3. The output, which may be developed across the load resistance of a cathode follower, is fed through a diode D2 to a storage capacitor C which has connected across it a leak resistor R2 represented by the voltage measuring circuit. A feedback loop comprising a capacitor C2 and resistor R4 feeds back to the input of the amplifier a proportion of the output voltage, the time constant C2, R4 being much greater than the pulse width. The feedback loop is connected to the junction of a resistor R5 and the cathode of a second diode D1, the fed-back voltage being proportional to the peak voltage on the capacitor C when the diode D2 is conducting and being maintained through the resistor R5 at other times.

Preferably the head has a flat cut away surface 10 that gives the head a shape complementary to an opposed recess or groove formed in the shank of the bit. The dimensioning of the head may be such that when it is entered into the groove or recess play exists between the head and the shank. The angle α between the face 10 and the axis of the bolt is preferably of a magnitude at least equal to the angle # between the axis of the bolt and the axis 3 of the socket. The forward end of the bolt is preferably directed to the inner end of the socket. The bolt may pass through a sleeve 6 of a high friction material to prevent accidental rotation of the bolt, the sleeve being housed in the mounting 5. The bolt end projecting outwards of the holder may be provided with means, e.g. a pin or cap, for engagement by a tool for rotation of the bolt.

Abstract: 668,932. Electric control systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. Feb. 2, 1950. [Feb. 2, 1949] No. 2742/50. Class 40 (i). [Also in Group XXXV] A servomotor arrangement for moving an adjustable member in accordance with variations of a variable such as liquid level or temperature, comprises a ferro-magnetic bar adopted to be reciprocated axially by an electromagnet energised with A.C. or rectified A.C. pulses in dependence on variations of the variable, the adjustable member consisting of a further electromagnet co-operating magnetically with the.bar and energised with halfwave rectified A.C. from a supply having the same frequency but 90 degrees out of phase with respect to the supply to the bar driving magnet whereby the adjustable member is moved one way or the other along the bar to follow up the variations. As shown, Fig. 1, variations in a liquid level cause a float F2 to upset the balance of a bridge 1, 2, 3, 4 fed from an A.C, source N1, N2, the out-of-balance voltage energising, if desired through an amplifier E, an electromagnet D the co-operating magnet armature A of which reciprocates axially a ferro-magnetic bar S at the frequency of the supply. A further electromagnet M rests on the bar S and on a further bar U parallel to S, the magnetic legs G1, G2 of the magnet M being grooved at Y, Fig. 5a, so as to be guided by the bar S. The magnet M is fed from the same A.C. source N1, N2, through a condenser C1 (which introduces a 90 degrees phase shift), a transformer T and half-wave rectifier L1. The magnet M acts similarly to a reversible ratchet and is stepped along the bar S by the oscillations thereof in a direction dependent on the phase sense of the bridge unbalance voltage until the bridge is balanced by the contact arm K1 rigid with the magnet M. The liquid level is recorded by a stylus I on a paper P or it may operate any other type of indicator. The amplifier E may include a thyratron push-pull output stage, Fig. 6 (not shown), to ensure substantially constant amplitude of oscillation of the bar S regardless of the magnitude of the bridge output, except of course for zero output. The magnet armature A in this case is replaced by soft iron. For measuring temperature, the bridge is unbalanced by a temperature sensitive resistor and rebalanced as above described.
