Title: High voltage electric insulation
IPC: H01B3/50
Filed: 1962-07-03
Abstract: 956,418. Insulation. DOW CORNING CORPORATION. July 3, 1962 [July 13, 1961], No. 25469/62. Heading H1A. Electric insulation having a dielectric strength above 225 volts/mil. of insulation thickness is formed by lapping a self-adhering silicone rubber tape, which tapers from its centre to its edges, around a conductor with adhesion of the tape to the conductor provided by a deformable. vulcanizable diorganopolysiloxane paste which fills the interstices between the tape and conductor and is then vulcanized. Examples of suitable siloxane polymers for making the rubber tape are given together with examples of fillers which may be employed with silica rubber for the formation of the tape including titania, zinc oxide, silica fillers &c. The selfadhering silica rubber is formed by addition of specific proportions of alkyl borates to silica rubber stock when the stock is vulcanized. Vulcanizing of the organosilicon rubber may be effected by heating with organic peroxides or by mixing with the polymer combinations of alkylpolysilicates or methylhydrogensiloxane or irradiation from a cobalt 60 source. Various paste compositions and their preparations are described together with the results of tests on the various forms. Specifications 688,602 and 740,573 are referred to.

Class 39(1) A thermionic valve for use at wavelengths between several metres and one centimetre is characterized in that the ratios of the effective capacity and the ballast capacity between the input electrode and the common electrode and between the output electrode and the common electrode are each approximately between ¢ and 2. The effective capacity is that part of the capacity which is directly proportional to the active surface area, and the ballast capacity the remaining inter-electrode capacity due to leads &c. Preferably the product of the ratios is about unity and each ratio is also about unity. Fig. 1 shows a cross-section of a double pentode of known design comprising two cathodes 1, control grids 2, screen grids 3, a common suppressor electrode 4 and two pairs of anodes 5 all surrounded by a screen 6.

Abstract: 1,125,762. Cutting. by fusion. BRITISH OXYGEN CO. Ltd. 11 June, 1965 [23 June 1964], No. 26012/64. Heading B3V. A metal cropping machine includes two metal cutting burners 28 and 30 mounted for movement along a boom in a direction transverse to that of a plate or billet 14 to be cut. The burners normally cut approximately half way through the workpiece from opposite sides, but are each able to be traversed along the beam a sufficient distance to cut through the entire workpiece should one of the burners become inoperative. Rods 36 and 40, connected to racks which are operated by electric motor driven pinions, serve to move the burners. The beam itself is vertically adjustable on a supporting pillar which is secured to a longitudinally movable base frame. The burners can be of the plasma torch or flame cutting type.
Patent GB-174117-A (GB)
Title: Improvements in or relating to the driving mechanism of talkingmachines or other apparatus normally operated by a spring-driven motor
Filed: 1920-09-09
Abstract: 174,117. Billing, N. Pemberton-. Sept. 9, 1920. Spring power-storing mechanism.-Relates to driving mechanism for gramophones and the like, of the kind in which an electromotor winds up a spring motor so as to produce a constant driving force. According to the invention, the electromotor is positively connected to one end of the spring to wind it, and is so designed as to be capable of maintaining the spring constantly but not fully wound. In the arrangement shown, a shunt-wound motor L is geared by a worm M to a worm-wheel N on an arbor F to which one end of a driving-spring is attached. The other end of the spring is connected to a barrel E which drives the turntable-spindle C through gearing E<1>, C<1>, a governor H being also geared to the spindle C. A hand switch Q for the motor-circuit is combined with a brake S adapted to act on the turntable. The motor L is so designed, and a resistance R in its circuit is so chosen, that when the circuit is closed by the switch Q whilst the turntable is held, the electromotor will tension the spring until the torque exerted by it holds the motor stationary. In this condition the spring is not quite fully wound. When the spring is allowed to drive the machine, the electromotor keeps the spring wound to its original tension. The armature-spindle of the motor carries a fan O, adjacent to the resistance R, so as to keep the resistance cool. Specification 7078/09, [Class 40 (ii), Phonographs &c.], is referred to. Reference has been directed by the Comptroller to Specifications 3535/00, [Class 139, Watches &c.], and 102,990.

Filed: 1952-10-17
Abstract: 709,617. Valves. GENERAL ELECTRIC CO. Oct. 17, 1952 [Oct. 19, 1951], No. 26096/52. Class 135 A pressure reducing valve for maintaining a desired pressure differential between the high and low temperature evaporators of a refrigerating system, comprises a casing 8 having a partition member 11 having an axial bore 13 loosely mounting a valve pin 16 to permit equalization of pressure on opposite sides of the member. The member has transverse slots 14, 22 intersecting the bore, and a recess 12 for a weighted plunger 17 engagable with lost motion with the pin 16. When the pressure in the high temperature evaporator connected at 9 exceeds that in the low temperature evaporator connected at 10 sufficiently to overcome the weight of the plunger, the pin 16 rises. Refrigerant then flows through the slot 14 to act on the upper side of the plunger to resist its upward movement and so delay the full opening of the valve. Downward movement of the plunger is delayed by the slow leakage of refrigerant trapped in the recess 12 past the leaky pin 16 and through the slot 22.

Filed: 1960-07-28
Abstract: An amorphous crystallizable linear polyester film is elongated in at least the transverse direction at a temperature between the second order transition temperature of the polymer and 50 DEG C. above this temperature.  The film is then stretched in its longest direction by an amount equal to its natural draw ratio at a temperature below the second order transition temperature of the polymer.  The film may be elongated in the first direction or directions by a factor of at least two.  The product may be heat set by heating it while held under tension to a temperature at least 25 DEG C. above the temperature of the first elongating step and below the crystalline melting temperature of the polymer.  The polyester may be derived from a glycol of the formula HO(CH2)n OH, where n is 2-10, and a dibasic acid, e.g. terephthalic, isophthalic, adipic, sebacic, bibenzoic, 1,2-dihydroxybenzoic or 1,5- or 2,6-naphthalic acid, but is preferably a polymeric linear terephthalic ester such as polyethylene terephthalate.  A film of the latter may be stretched to at least twice its original width at 70 DEG -120 DEG C., after which its temperature may be reduced to below 69 DEG C. but above 20 DEG C. and the film stretched by at least five times its original length at such a temperature.  The film may then be heat set at 150 DEG -250 DEG C. while held under tension.  Films produced according to the invention have a continuous integral metallic lustre.
