Abstract: 916,298. Coating with metals. GENERAL MOTORS CORPORATION. Oct. 18, 1961 [Nov. 17, 1960], No. 37396/61. Class 82 (2). A method of making a hollow metal article comprises plasma-jet spraying of metals on to a mandrel and then removing the mandrel to leave the required article. The mandrel is constructed as shown in Fig. 2, in which there is a wooden core 12, a thin sheath 20 (e.g. A1 0.02 to 0.04 inch thick) and an interlayer 16 of rubber on plastic. This assembly is held by bolt-head 36 in a chuck (not shown) and rotated during the spraying, the spraying means itself also being oscillated.

Title: Electrical signal translating apparatus
IPC: H03K3/02
Filed: 1968-08-08
Abstract: 1,210,550. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORP. 8 Aug., 1968 [4 Dec., 1967], No. 37791/68. Heading H1K. [Also in Division H4] The nucleation of high-field domains in a semi-conductor body 1 exhibiting the Gunn effect between electrodes 7, 9 is delayed by the provision of capacitive means coupled to the body 1 along part or all of its length. As shown the capacitive means comprise the depletion region 23 of a reverse-biased PN junction 21 between a P-type substrate 3 and an N-type epitaxial body 1 thereon. A first domain 5 nucleated adjacent the cathode electrode 7 advances across the body 1, progressively discharging the capacitance constituted by the depletion region 23, until when the domain reaches the anode electrode 9 the region 23 is completely discharged and the body 1 is no longer in a condition to allow nucleation of a new domain. After a delay, during which the region 23 recharges, the nucleation condition is re-established in the body 1, and a further domain traverses the body. The delay time is preferably about equal to the domain propagation time, so that the output across either of loads 11 or 17 is approximately square-waye. The voltage supply 19 for the capacitive coupling means may be variable, thus producing an amplitude-modulated output from the oscillator. The loads 11, 17 may be resistive or resonant. In an alternative form the capacitive coupling is provided by a reverse-biased Schottky barrier. Preferred materials for the N-type body 1 are GaAs, InP, InAs under pressure, ZnSe or CdTe.

Title: Improvements in torsion spring devices
IPC: F16F1/06
Filed: 1957-12-04
Abstract: 872,327. Non-metallic springs. REGIE NATIONALE DES USINES RENAULT. Dec. 4, 1957 [Dec. 19, 1956], No. 37795/57. Class 108(3). A torsion spring 1, Fig. 1, of plastics material, i.e. a synthetic resin or a polymer or modified polymer of natural origin, has fixing lugs 2, 3. Figs. 4, 5 show a spring having three spires, 12, 13, 14, lugs 9, 10 stiffened by ribs 20 and a central rod 15 retained by head 16 which stiffens the spring. The diameter of rod 15 can be chosen to limit the reduction in diameter of the spring brought about under tension and thus limit the amount of rotation of one lug which is possible relative to the fixed lug. A further spring, Fig. 6, not shown, has two fixed lugs and a central movable lug. Moving the central in one direction puts one spring under tension whilst the other spring is free to rotate since the springs are connected to the fixed lugs by keys. Stops prevent movement in one direction only so that the appropriate spring is tensioned whichever way the central lug is moved. This arrangement ensures that the springs are always tightened up, not unwound when placed under tension. In a further embodiment a flat spiral spring having three spires extends between a body 35 and a core 39 which is turned by a square ended spindle 46 to tension the spring. The height of the spires decreases towards the core to provide a variable rate and a dust cap 45 is provided. In a modification of the previous embodiment one spire of varying thickness is provided.

Title: Carbon articles
Inventor: BICKERDIKE ROBERT LEWIS
IPC: C04B35/52
Filed: 1959-11-20
Abstract: Carbon articles are made by lightly consolidating in a mould a charge of carbon powder of very small particle size and subjecting it to a carbon deposition process whereby carbon is deposited by pyrolysis from a gas or vapour of a carbon compound throughout the charge on to the particles, thereby bonding the particles together to form a unitary porous carbon article. This may be removed from the mould and the carbon deposition repeated to produce a substantially impermeable article.  Alternatively, after removing from the mould, the article may be pulverized to powder and the whole process repeated.  The deposition step may consist of heating the charge to 500 DEG  to 1500 DEG  C. whilst flowing the gas or vapour through the mould, at sub-atmospheric to slightly above atmospheric pressure.  The consolidation may be effected by vibration or pressure and the final article may be graphetized.

The luminescent screen of a cathode-ray tube 1 (Fig. 1) is protected from damage by the provision of an auxiliary bias source (shown schematically as a battery) 10 which, on switching-off the equipment, causes the production of an intense beam to discharge the wall anode fed from the EHT supply 11 before the deflection of the beam ceases. The source 10, poled as shown, is connected in series between the control electrode 6 and the brightness control bias potentiometer 8, the actual potentials on the cathode 2 and electrode 6, Uk, Ug respectively, being shown in Fig. 2 together with the potential Ugk of electrode 6 relative to the cathode and the potential E of source 10. On switching off the equipment at time t 1  the P.D. Ugk decreases negatively until time t 2  after which it increases positively towards the value E and produces an intense electron beam which discharges the tube wall-anode, the decay rate of the deflection circuits being such that discharge is substantially complete before deflection of the beam ceases. In practice, the source 10 comprises a capacitor which is charged (to about 40V) by rectifying positive or negative pulses (such as the blanking pulse 13) derived either directly from the horizontal recurring circuit (Figs. 3 and 4 respectively, not shown) or from separate windings on the horizontal transformer (Figs. 5 and 6, not shown). For automatic contrast adjustment as a function of ambient brighteners, a photo-sensitive resistor (F) may be shunted across portion of potentiometer 8 (Fig. 7, not shown).
