Abstract: 1,255,945. Valves. EXPERT INDUSTRIAL CONTROLS Ltd. 25 Feb., 1969 [1 March, 1968], No. 10083/68. Heading F2V. A spherical valve member 12 and a seat 11 are movable relatively toward and away from each other to control flow through the seat opening 13. One of the members is of resilient material. The presented surfaces of the members are such that an initial circle of contact between them contracts to a smaller circle of contact as they are pressed closer together. Thereby the area of the valve member exposed to pressure through the seat opening also contracts. It is stated that positive closure results, owing to the resisting force decreasing as the valve close, and conversely that the valve opens quickly and positively without any tendency to bounce. Preferably the seating member 11 is resilient.

Title: Sulfonation of alkenyl aromatic polymers
Inventor: ROTH HAROLD HERMAN
IPC: C08F8/34
Filed: 1962-03-19
Abstract: Polymer sulphonates are prepared by admixing a benzene soluble alkenyl aromatic polymer with sulphuric acid in the presence of a chlorinated hydrocarbon (e.g. methylene chloride or perchloroethylene) and wherein agglomeration of the partially sulphonated polymer is substantially reduced by the presence of a suspension stabilizer.  The specified stabilizers are clays, silica, diatomaecous earth, hydrous metal oxides which have been surface treated with organo silicon compounds (e.g. treated oxides of Al, Ti, Fe or Si), aminated aluminium silicates (e.g. aminated bentonite), and polymers such as polyethylene, graft polymers of acrylic acid or vinyl pyrrolidine on polyethylene, trimethylamine derivatives of styrene/chloromethylstyrene copolymers, and copolymers of vinylidine chloride with acrylonitile, or dichlorostyrene with ethynylcyclohexanol\sBstyrene. In examples ammonium and sodium salts of the polymer sulphonates are obtained by treatment with ammonia or sodium hydroxide.

Title: Improvements in or relating to amplitude selection circuit
Inventor: CIRCUIT MARTIN PHILIP
IPC: H03K9/02
Filed: 1959-03-26
Abstract: 933,262. Valve pulse limiting circuits. INTERNATIONAL COMPUTERS & TABULATORS Ltd. March 11, 1960 [March 26, 1959], No. 10549/59. Class 40 (6). In a voltage amplitude selector comprising an amplifier having regenerative feed-back via a transformer, an output signal is generated each time the amplitude of an input signal exceeds a selected voltage derived by adding a voltage dependent upon the average amplitude of input signal to a reference voltage. As shown, the signals from a magnetic reproducing head 2 are amplified at 4 and fed via a transformer 5 to a multiar voltage sensitive circuit 7. Valve 20 is normally conductive, diode 27 being biased off by the flow of grid current in resistor 26 so that the regenerative feed-back loop via transformer 22 is broken. When the signal voltage rises above that at lead 8, diode 27 conducts, closing the regenerative feed-back loop so that the valve 20 is rapidly cut off. The rise in anode voltage is fed via a cathode follower 21 to a differentiating circuit 36, 37 which provides a positive pulse for the amplifier 38. The negative pulse at the output of transformer 41 is passed via diode 42 to change the state of the bi-stable circuit 13. The output voltage remains at this level until the next signal of opposite polarity, which operates a similar voltage sensitive circuit 6, 9, 10 to restore the state of the bi-stable circuit 13 and hence restore the level of output voltage. The selected voltage at lead 8 is generated by amplifying the input signals at 54, and feeding them to a full-wave rectifier 57 which provides a voltage dependent on the average value across capacitor 58. The average voltage is added to the manually adjustable reference voltage from potentiometer 50 and fed via a cathode follower 45 to lead 8. Potentiometer 53 is adjusted so that the multiar circuits are triggered at two-thirds the peak value of the input signals.

Title: Improvements in and relating to electric regulating systems
IPC: G05F1/26
Filed: 1932-04-13
Abstract: 400,202. Automatic regulation. BRITISH THOMSON. HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Garman, G. W. ; 98, Reynolds Street, Scotia, New York, U.S.A.) April 13, 1932, No. 10613. Convention date, April 17, 1931. [Class 38 (iv).] The voltage of an alternating-current circuit 10 is regulated by connecting in the circuit the secondary winding 14 of a booster transformer 11 having a centre-tapped primary winding, the two halves 12, 13 of which are alternately energized through a pair of electric valves 19, 20, the output of which is regulated, in accordance with the voltage of the circuit 10, by controlling the phase relation between the grid and anode potentials by means including a voltage responsive bridge. In the form shown, the grid circuits of the valves are energized through a static phase shifting circuit comprising condensers 24, 25 and a variable impedance 26 connected in series across the circuit 10. One of the condensers 25 is connected to the primary winding of a grid transformer 27 with a divided secondary winding connected to the grids. The impedance 26 is in the form of a transformer, with a secondary winding short-circuited through a pair of valves 43, 44, the conductivity of which varies in response to variations in the voltage of the circuit 10. Such variations upset the balance of the bridge, which comprises pairs of resistances 29, 31, and 30, 32 with dissimilar characteristics, and energize the primary winding of a transformer 40 controlling the grid potentials of valves 36, 37 which are connected in a circuit including a condenser 35 and a transformer 33 connected across the circuit 10. The variations thus produced in the potential of the condenser 35 effect corresponding variations in the conductivities of the valves 43, 44 and hence in the impedance of the transformer 26, thereby advancing or retarding the phase of the grid potentials of the valves 19, 20 to effect the required changes in the voltage supplied to the booster transformer 11. Specifications 399,240 and 400,206 are referred to.

Title: Process for rendering films of cellulose substances impermeable
IPC: C08J7/14
Filed: 1934-04-09
Abstract: Cellulose films are rendered impermeable to moisture by treatment in a bath which has the effect of esterifying both the cellulose and the glycerine contained in the film, and are varnished either by including the varnish in the esterification bath or by treating with the varnish after the esterification treatment.  In the former case, the ratio of the quantity of the dry substances of the varnish to that of the esterification substances varies between 1 : 20 and 3 : 10.  The varnish preferably comprises esters or ethers of cellulose. Suitable esterifying agents mentioned are nitric acid, phosphoric acid, formic acid, acetic acid, and abietic acid.  After leaving the bath or baths, the film may be kept for a time in a room charged with the vapours of the varnish solvent, e.g. in a concentration of 2 to 40 per cent, and then dried at 40 to 100 DEG  C. in an atmosphere having a relative humidity of over 40 per cent.  The Specification as open to inspection under Sect. 91 relates to a process for rendering cellulose films impermeable by treating with a mixture of solutions having the power of "etherification" simultaneously on the cellulose and on the glycerine contained in the films.  This subject-matter does not appear in the Specification as accepted.
