Patent GB-572429-A (GB)
Title: Improvements in or relating to waggons for draw-benches and like apparatus
IPC: B21C1/28
Filed: 1943-11-19
Abstract: 572,429. Drawing-tongs. NORTHERN ALUMINIUM CO., Ltd., and WHITTLE, W. Nov. 19, 1943, No. 19368. [Class 83 (iv)] A wagon for a drawbench tongs has retaining means that normally hold the hook clear of the chain, together with means for effecting release when desired. The hook 3, Fig. 1, is maintained in the raised position clear of the chain 1 by a catch 9 engaging a hook 10 on a spring-biassed lever 11 carried by a bracket 8, on the wagon, that also supports a spring 7 that is unstressed in the position shown. On moving the lever 11 the hook 3 descends under gravity to engage the chain, and at the same time stresses the spring 7. When the load comes on the chain, since the pivot of the hook is above the path of the chain, the hook assisted by the spring 7 rises, lifting the chain, until the catch 9 reengages. At the end of a draw, removal of the load from the hook releases the chain which drops to its normal position, leaving the wagon free to be returned prior to another draw. To prevent accident should the grippers fail to engage, the tube &c. and the hook consequently remain in engagement with the chain in its lowered position, a detent 15 engages a cam 14 on the hook lever to effect disengagement of the hook from the chain and re-engage the catches 9, 10.

Title: Frequency modulation detector and converter
IPC: H03D3/08
Filed: 1943-11-23
Abstract: 571,314. Circuits for sound reproduction. PHILCO RADIO & TELEVISION CORPORATION. Nov. 23, 1943, No. 19574. Convention date, Nov. 24, 1942. [Class 40 (iv)] [Also in Group XL] A frequency discriminator for detecting or converting a frequency-modulated carrier wave comprises a filter network of either the bridged- T or the parallel-T type. In Fig. 1, the tuned circuit of a reaction oscillator 7 includes a phonograph pick-up 9 of the variable-inductance type described in Specification 558,680. The frequency-modulated output is fed to a bridged-T network 1 comprising series condensers C/2 bridged by a resistance 4R and a shunt inductance L of resistance R. This network has a transmission characteristic as shown in Fig. 2 and the mean oscillation frequency is such that the network operates midway along the slope A of the curve, giving an amplitude-modulated output which is rectified in the grid-cathode circuit 4, 5 of the valve 6. Other electrodes of this valve are connected to a tuned circuit 13 to produce radio-frequency oscillations which are amplitude-modulated by the audio voltages on the grid 4. These oscillations are radiated and are picked up by a nearby broadcast receiver to reproduce the record traversed by the pick-up 9. The zero transmission frequency of the network may be adjusted by a movable comminuted iron core in the inductance L (Fig. 3, not shown). Two such networks and two rectifiers associated in balanced relation may be used with their zero transmission frequencies symmetrically displaced on either side of the operating frequency (Figs. 5 and 6, not shown). Fig. 4 shows a modified network comprising two T-sections in parallel, one section comprising two series resistance 2R and shunt condenser C, the other section comprising two series condensers C/2 and a shunt resistance R. The zero transmission frequency is given by WCR=1. The Specification, as open to inspection under Sect. 91 refers also to an arrangement in which the network 1, Fig. 1, is employed for amplitude modulation by feeding a carrier to it, and by using an inductive phonograph pick-up as the coil L. This subject-matter does not appear in the Specification as accepted.

Filed: 1935-07-09
Abstract: 459,306. Weighing-apparatus. TOLEDO SCALE MANUFACTURING CO., Toledo, Ohio, U.S.A. July 9, 1935, No. 19599. Convention date, Sept. 15, 1934. [Class 143] Printed records, apparatus for giving.-In a weighing-scale having a rotatable printing disc automatically set according to the load, the printing disc is provided with a number of spaced apertures adapted to be selectively engaged, for positioning the chart, by a pair of plungers which have a spacing unequal to the spacing of the apertures, and which, upon movement towards the chart are capable of a relative motion so as differentially to select one of the apertures for one of the plungers to enter. When a load is placed on the machine the printing disc 49 receives a proportionate rotation to present the appropriate character (etched upon its face) to a printing platen 63. The operator inserts a ticket through a slot 132 and presses a push button switch of the transitory type, causing a pulse of alternating current to flow through a rectifier. Direct current from the rectifier energizes a magnet 94 the armature of which rocks an arm 97 and advances a plunger frame 103 towards the printing disc 49. The plunger frame carries two spring-pressed plungers 104, 105, Fig. IX, having respectively blunt and sharp conical heads, and during the advance of the frame one of the plungers enters one of the holes in the printing disc so as to set the disc in precise position for printing a character. The other plunger abuts against the face of the printing disc and rocks a pivoted equalizer 103<2> so as to bear against the entering plunger and press it more firmly into its aperture. One of the plungers is arranged to engage the printing disc before the other. The armature of the magnet 94 in moving closes the circuit of a solenoid 74, and the core 73 moves upwards. A toggle connection from the core slides an abutment 56 and the platen 63 towards one another to make the impression on the ticket. In its uppermost position the core opens a switch and the circuit condition is restored to the original state. During the operation of the printing mechanism a pawl 83 advances an inking ribbon 79 over the platen 63, and tension member 80, from a spring-pressed spool 78 to a second spool 81.

Abstract: 653,491. Valve gear. ARMSTRONG WHITWORTH & CO. (ENGINEERS), Ltd., Sir W. G., and MANSFIELD, W. P. Oct. 11, 1944, No. 19601. Drawings to Specification. [Class 7(vi)] [Also in Group XXIX] A valve-actuating gear is constructed so that when the engine is operating at the correct speed the valve is actuated mainly by its reciprocating mass which is resiliently mounted to produce this effect, the amplitude of its motion being kept up by a small intermittently-applied force. This force may be applied by (a) mechanical means-e.g. by an engine driven cam; (b) cylinder pressure, the valve being masked to enhance the pressure effect; or (c) electrically by connecting the valve to the core of an electromagnet actuated by an alternating current. The resilient mounting may comprise opposed springs, the frequency of vibration of which may be varied, or opposed pneumatic pistons. The engine is motored up to the correct speed, when a governor may be arranged to disconnect the motor. A converted enginedriven generator may be used for this purpose. Specification 653,490, [Group XXIX], is referred to.

Filed: 1950-08-14
Abstract: In a process for separating acetylene from a gaseous mixture, the acetylene is recovered from solution in acetyl acetone or ethylene diacetate by heating with water to the consolute temperature.  The resulting homogeneous solution separates on cooling into solvent and water which are used again in separating and recovering further quantities of acetylene.ALSO:In a process for separating a desired gas from a gaseous mixture the said gas is recovered from its solution in a liquid with temperature up to a temperature at least one additional liquid, whose miscibility with the absorbing liquid increases with temperatures up to a temperature at which it becomes complete, to a temperature at least as high as this last mentioned temperature, whereby the said additional liquid dissolves in, and expels the desired gaseous constituent from, the absorbing liquid. One additional liquid is preferably used forming one liquid phase at the regeneration temperature and two liquid phases at lower temperatures.  The relative proportions of the two liquids are preferably selected so that the composition of the mixture used in the regeneration stage is approximately the consolute temperature. The examples describe the recovery of acetylene, acetyl acetone or ethylene diacetate being employed as the absorbent liquid and water as the additional liquid.
