IPC: B21D43/14
Filed: 1931-11-20
Abstract: 383,070. Moulding saggers or like pottery supports. EDWARDS, W. H., Burnside, Rough Close, Stoke-on-Trent, and CONNELLY, W. T., Hartwell, Sneyd Avenue, Newcastle-under- Lyme. Nov. 20, 1931, No. 32225. [Class 87 (ii).] The movement of the vertically moving die in a machine for moulding saggers, also controls the feeding and delivery mechanism so that the whole operations of the machine take place in timed relation. The downward stroke of the movable die shaft 5, effected through the agency of the crank 11 and slotted arm 9, also causes pivoted levers 24, 25 to oscillate by means of the eccentric slot 21. The lever 24 moves a rotating table 28 step by step through pawl and ratchet gear and thus enables rough blanks on the table to fall one by one through holes into a pivoted scoop 29. In addition the inward movement of the lever tilts the scoop against the action of a spring by engagement with the projection 37, thus delivering the blank to the lower die 20 as shown in Fig. 3. On the upward movement of the die shaft the lever 25 swings a delivery shoot 40 laterally into position to receive the moulded article when stripped from the die by the axial movement of spring pins 39 when they abut against the fixed head 8.

Abstract: Articles of rubber and the like are produced from aqueous dispersions thereof by coating supports or backing strata with a non-coagulating composition comprising one or more polyhydroxy compounds or their derivatives in admixture with one or more volatile solvents and then with the aforesaid aqueous dispersions and finally coagulating the deposits.  The polyhydroxy compounds used are those which have a slight stabilizing action such as the polyhydric alcohols or their derivatives such as glycerol, glycol, dithylene glycol, or alkyl ethers of these such as glycol monoethyl ether.  Examples of suitable volatile solvents are acetone alcohol and ether.  The coagulation can be effected by the action of heat, with or without the application of coagulating agents and/or setting and dehydrating means.  The formers used may be heated electrically or by steam, during the immersion in the aqueous dispersions and/or after their removal from the dispersions.  Coatings of appreciable thickness may be applied by alternating coatings of coagulating media and the above aqueous dispersions.  The supports or backing strata may be of glass, metal, porcelain, hard or soft rubber, clay or fabric.  The aqueous dispersions of rubber and the like may contain additions of aqueous dispersions of rubber-like substances such as synthetic rubbers, mineral rubbers, factice, reclaim, oils such as rape oil or vulcanized oils, cellulose esters or proteins.  The usual fillers and vulcanizing agents may also be added.  In an example a former is wiped with a solution composed of 5 per cent glycerine and 95 per cent alcohol, allowed to stand 1 minute, and dipped in a usual rubber mix, rotated and placed over a jet of steam.

Abstract: 1438433 Telemotors SOC ANON AUTOMOBILES CITROEN 26 July 1974 [6 Aug 1973] 33233/74 Heading F1P [Also in Division F4] In arrangements for controlling the orientation of motor vehicle head-lamps in response to the steering mechanism in which a hydraulic powertransmitting circuit 12 has a transmitter 8 associated with the steering linkage 2, 3 and a receiver 11 associated with a movable head-lamp 16, there is provided a correcting hydraulic circuit 19 for compensating for thermal effects in the power-transmitting circuit 12 where the vehicle is moving in a straight line, wherein the correcting circuit 19 connects an auxiliary distributer 24 into the power-transmitting circuit 12 only when the steering mechanism is in the straight-ahead driving position, e.g. by means of stop-valve 18, the auxiliary distributer 24 connecting either with a source 29 of hydraulic liquid under pressure or with an exhaust 30 for discharging excess such liquid to appropriately compensate for irregular conditions in the power-transmitting circuit 12. The arrangement operates as follows:- If, in the straight-ahead driving position, the volume of the hydraulic liquid in the power-transmitting circuit 12 is either too great or too small then the headlamp will be displaced, respectively, to the right or the left of its centre position. This displacement is transmitted through torsion element 28 and pivotting member 26, 27 to displace the double-acting piston 24a of the auxiliary distributer 24, respectively, to connect either the liquid exhaust 30 or the liquid supply 29 to the central annular cavity 24c of the distributer 24. This cavity 24c is also connected via circuit lines 19a, 19b through cut-off valve 18 to the powertransmitting circuit 12 at compression chamber 8c of transmitter 8, thereby compensating liquid volume irregularities in the circuit 12. The stop valve 18 comprises a valve member 20 and a spring 21 disposed in a bore 18b, the valve member 20 being operatively connected to a cam 22 rigidly attached to the steering linkage 26 such that in the straight-ahead driving position the valve member 20 urged by the spring 21 engages in a bottom dead centre cavity 22a in the cam 22 thereby permitting connection of the two circuit lines 19a, 19b in the bore 18b. For all other positions of the cam 22 the piston 20 is urged against the spring 21 to close this circuit line inter-connection thus isolating the auxiliary distrubuter 24 from the power-transmitting circuit 12.

Abstract: 670,690. Electron discharge apparatus. ZENITH RADIO CORPORATION. Dec. 29, 1949 [Dec. 30, 1948], No. 33245/49. Class 39 (i). A discharge device comprises a cathode having a flat emission surface, an auxiliary electrode at least a part of which is coplanar with the emission surface, an apertured focusing electrode, and an accelerating electrode which is arranged on that side of the focusing electrode remote from the cathode and has an aperture the boundaries of which extend towards the cathode such that the distance between the boundaries of the aperture in the focusing electrode and those in the aperture of the accelerating electrode are not greater than onehalf of the transverse dimensions of the second mentioned aperture. In an amplitude limiter and frequency demodulator, the portion 16, Fig. 1, of the auxiliary electrode 13 is coplanar with the cathode 12 heated by member 11 to produce a divergent beam which is focused by slotted electrodes 14, 15. The width of the flanged slot 17 in the anode 15 is 0.030 inch and the distance between the flanges 18 and the boundaries of the aperture 14a nearest the cathode are 0.01 to 0.015 inch. A focusing electrode 19, in hair-pin form, is followed by first control grid 20, a converging lens focused by members 21, and screen grid 22 connected to anode 23, focusing electrode 25, second control grid 26 and anode 28. The apertures in the electrode 19, 25 are larger respectively than those in the electrodes 17, 23 and the control grids are spaced from the anodes 15, 23 by distances which are respectively greater than at least one of the transverse dimensions in the anode apertures. The control grids 20, 26 may consist of parallel wires spaced respectively at 80 and 68 per inch; both may have a radius of curvature of <SP>5</SP>/ 16  inch. Electrodes 13, 14, 19, 21, 25 may be internally connected to the cathode. In a modification, the electrodes 16, 14, Fig. 2, anodes 15, 23 and electrodes 19, 21 respectively form structural units. The electrode arrangement may be used in a velocity modulation or travelling-wave tube or in a frequency demodulating circuit in which the first control grid 20, Fig. 3, is fed from the intermediate amplifier of a superheterodyne receiver and the second control grid 26 is connected to a circuit 35, tuned to the intermediate frequency so that the space charge coupling between grids 20, 26 causes the voltage induced on grid 26 to lag that on grid 20 by 90 degrees. Frequency variation of input signal causes a change in the phase relationship between the voltages on grids 20, 26 and hence in the anode current. The circuit is unresponsive to amplitude variations owing to the step-like characteristic of the control grids. The condenser 37 may be formed by the capacity of the circuit. Specification 670,636 is referred to.
