Abstract: 273,673. British Thomson-Houston Co., Ltd., (Assignees of Jones, N. R.). June 20, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Condensers have their rotor and/or stator plates perforated as at 12, 13, respectively so that, with a given fixed inductance, they may have a straightline value of tuning either with regard to frequency or to wave-length over the whole range of operation, which range may be more than 180 degrees so that stops are not necessary. As shown, the perforations for a straight-line frequency condenser have one edge extending radially and another circularly. The Specification contains two curves showing certain relation between capacity and angle of rotation.

Title: Process of polymerizing vinyl and acrylic compounds
IPC: C08F259/04
Filed: 1956-05-14
Abstract: Vinyl monomers are polymerized in aqueous emulsion in the presence of a polymerization catalyst and a polymer seed latex containing particles of a predetermined size and concentration and which has been mixed with an emulsifier or protective colloid in such an amount that all of the emulsifier is bound physically to the surfaces of the polymer particles in the seed latex, i.e. there is no free emulsifier present during the polymerization. The polymerization may be effected batchwise or continuously and the latex, and aqueous solution of the catalyst may be added portionwise or continuously.  The monomer exemplified is vinyl chloride and the latex seed polymer used polyvinyl chloride.  The emulsifier exemplified is a mixture of sodium laurate and sodium hydroxide.  The polymer made by the process may be recovered by spray-drying and subsequently compounded with dioctyl phthalate to give a paste.  Specifications 355,202 and 627,265 are referred to.

Abstract: 767,735. Automatic gain control. KOLSTER-BRANDES. Ltd. May 20, 1955 [May 21, 1954]. No 15078/54. Class 40(5)  In an automatic gain control circuit in which an amplifying stage 1 is resistancecapacity coupled to a diode 11, from which an A.G.C. voltage is obtained over smoothing network 9, 10, a delay bias is applied to the cathode of diode 11 via smoothing condenser 15 and a potentiometer 12 which is connected between anode and cathode of the valve 1. In this way any overloading of the valve 1, resulting in a reduction in anode potential, causes a reduction in the delay bias on the diode 11 so as to increase the A.G.C. voltage. As applied to a television receiver the potentiometer 12 may be made adjustable and used as a contrast control.

Title: Kallikrein-inactivator
IPC: C10L1/18
Filed: 1955-05-25
Abstract: A kallikrein inactivator is produced from the organo of cattle, e.g. lymph and parotid glands, pancreas, liver and spleen, by extraction with a mixture of one part by volume normal acetic acid and two to three parts of a water miscible alcohol, e.g. methanol, ethanol, or from colostrum diluted with an equal volume of water, and blood serum by extraction with a water-miscible alcohol containing 1.5 to 3.5 per cent by volume of alcohol, glacial acetic acid, at a pH of about 4 to 6 and at an elevated temperature, e.g. about 50 DEG  C.  The extract is concentrated in vacuo, extracted with ether and the inactivator precipitated by the addition of a water-miscible organic solvent, e.g. ethanol, acetone.  The precipitate may then be dissolved in a dilute acid, e.g. acetic acid, the solution made weakly alkaline by addition of ammonia to a pH about 8 to precipitate inert material, and the inactivator precipitated from the separated solution by the addition of a water-miscible organic solvent.

Title: Improvements in or relating to safety devices for gas fuel pipes or tubing
Inventor: WITT PAUL
Filed: 1964-04-15
Abstract: 1,029,894. Controlling gas burners. TESPA A.G. April 15, 1964, No. 15505/64. Heading F4T. [Also in Division F2] A safety device for preventing explosions in the gas pipes of burners comprises a flame trap 33 made of sintered metal or glass or glass fibre or synthetic plastic, a pressure relief valve 34 and a back pressure check valve 30 which is arranged to close in both directions of gas flow. The check valve 30 comprises a rubber disc urged by a spring 32 to seat on an upper seat 29 and urged by the gas flow to seat on a lower seat 31. The gas enters the device through an inlet 21 and flows past the check valve, which normally floats in the position shown in Fig. 5, to an outlet 22. The device also has a gas inlet valve comprising a rubber disc 37 pressed by a spring 46 against a seat 36 and adapted to be opened by a bell-crank lever 40 connected to the stem of the valve. The inlet valve is held in open position by balls 44 projecting through holes in a fixed collar 45b and engaging a shoulder on the valve. The balls are held in projected position by a bulbous part 45a on a stem 45 secured to the check valve 30. If a flash-back explosion occurs the check valve 30 is pressed so tightly against its upper seat 29 that the centre of the valve displaces the stem 45 to release the balls 44 and the inlet valve 37 closes. The pressure relief valve 34 opens. If a pipe downstream of the device fractures, the increased gas flow causes the check valve 30 to seat on the lower seat 31; the balls 44 are again released so that the inlet valve again closes. A bleed passage 47 in the lip of the lower seat 31 allows the pressure on both sides of the check valve 30 to equalize so that the valve again opens. In a simple embodiment, Figs. 1-4 (not shown), no gas inlet valve is provided and the pressure relief valve has a spring urged pin which engages the face of the valve when the valve is fully open and prevents it from closing.
