Abstract: 927,862. Valve sawtooth circuits; cathode-ray tube circuits. SPERRY RAND CORPORATION. Sept. 25, 1959, No. 32710/59. Classes 40 (6) and 40 (7). The deflection waveform for a cathode-ray tube is obtained by combining proportions of the waveforms present at the grid and anode of one valve of a multivibrator. In Fig. 1, valve 1 is rendered conductive by a positive trigger pulse fed to the grid, cutting off valve 2 and allowing capacitor 18 to discharge to provide a sweep waveform B. The D.C. level of waveform B is centralized by adding the pulse A from the anode of valve 2 by means of a potentiometer 7. The combined waveform is fed via an A.C. coupled push-pull amplifier 22 to the plates of a cathode-ray tube 40. The relative amplitude of waveforms A, B and hence the centring of the trace is controlled by potentiometer 7. Waveform A is also fed to the grid of the cathode-ray tube as a brightening pulse. A capacitor 25 is provided to reduce the rise time, thus ensuring that only the linear part of waveform B is displayed. In Fig. 3 (not shown), waveforms A, B are added in a summing circuit consisting of one fixed and one variable resistor connected to top of the sweep length potentiometer.

Abstract: 1,055,586. Washing machines. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 31, 1963 [Aug. 28, 1962], No. 33009/62. Heading D1A. In an automatic combined electric washing and spin-drying machine the tub 109 is driven at slow or fast spinning- speeds according to the fabric by controlling the period of drive from motor 112 to gear-box 111 through a slipping clutch 119, the gear-box 111 being free and coupled directly to the tub through a hollow shaft 110. The gear-box and tub 109 are held by a brake 115 for the washing operation and agitator 102 oscillated by opposite rotation of the motor 112 acting through gearing 111 and shaft 105. The high or low spinning speed is selected by closing a contact 51, Fig. 1 (not shown), to 50 or 52 to make a circuit through either of contacts 28, 30 or 27, 25 which are closed for a long or short period by timer operated cams. The automatic 'operation is initiated by closing a mains supply switch 1,2,3,4, Fig. 1 (not shown) to energize indicating lamp L and a thermostatically controlled mixing valve from hot and cold water supplies to fill the tub. When the tub is filled to correct level a pressure-responsive switch shuts off the supply and energises the circuit of the drive motor M and that of a timer motor TM. The latter operates stepwise to drive cams for actuating contacts of the desired washing and drying cycle. A water heater WH (116 in Fig. 4) may also be provided for an initial water heating phase and a heat control switch is provided to select the required temperature. Contacts 61, 62 and 63, 64 controlling the brake 115 and the driving motor M are controlled by the lid of the machine to ensure that the lid is not open during spin-drying.

Title: Improvements in and relating to methods of production of polymers and copolymers of acenaphthylene
IPC: C08F2/00
Filed: 1949-12-28
Abstract: Polymers of acenaphthylene and copolymers with isoprene, butadiene, or styrene are made by polymerization, e.g. by heating, in the presence of a liquid aromatic or alkyl-substituted aromatic solvent for the monomers, e.g. benzene, ethyl benzene, an emulsifying agent dispersed in water and a polymerization catalyst.  Specified catalysts are potassium persulphate, benzoyl peroxide, t-butyl dydroperoxide, t-butyl perbenzoate, t-butyl diperphthalate, acetyl peroxide, acetyl benzoyl peroxide, peracetic acid, lauroyl peroxide, and butyryl peroxide.  The emulsifying agent may be a higher fatty acid, e.g. stearic acid, or dioctyl sodium sulphosuccinate or mixtures, and is preferably added to the mixture dispersed and dissolved in an aqueous potassium hydroxide solution.  The polymer is isolated by adding a coagulating agent, e.g. dilute hydrochloric acid, methyl alcohol, ethyl alcohol, acetone or propyl alcohol, redissolving the coagulated polymer in a solvent, e.g. benzene and re-precipitating by adding a non-solvent, e.g. methyl alcohol. Specification 598,857 is referred to.  The Specification as open to inspection under Sect. 91 comprises also ethyl dibenzylfuran as a solvent for the monomers.
