Title: Improvements in or relating to the use of polysiloxanes in the manufacture of cellular polyurethanes
Inventor: TWITCHETT HARRY JAMES
IPC: C08J9/00
Filed: 1962-06-28
Abstract: Cellular polyurethanes are prepared by a conventional process, by reaction of organic polyisocyanate with hydroxyl-containing polymers which have at least two isocyanate-reactive groups per molecule, in the presence of water and/or a low boiling point liquid blowing agent, the process being characterized in that the reaction mixture contains a polysiloxane having at least one unit of general formula <FORM:1044629/C3/1> wherein R is a monovalent hydrocarbon radical which may be substituted; X is a divalent organic radical of two or more C atoms; Y is a polar water-solubilizing radical forming a salt with Z, which is a radical or ion of opposite charge to Y; and a is 0 to 2.  X may be any divalent hydrocarbon radical, and may be substituted, or may be interrupted by hetero-atoms (e.g. O, S or N), or groups containing such atoms.  Y is a polar group of one positive or one or two negative charges, e.g. (-OSO3)-, (-SO3)-, (-SO2)-, (-PO3)-, or (-COO)-, or alternatively <FORM:1044629/C3/2> and Z is a group neutralizing Y to form a salt, e.g. Na+, K+, NH4+, or substituted ammonium, divalent metal ions, or dialkyl tin, or alternatively (-OH)-, halide, (-NO3)-, (-CH3COO)-, methosulphate, phenoxide, or paratoluene sulphonate. The group YZ may also be an internal salt, or "zwitterion."  R is preferably methyl, phenyl, phenyl-ethyl, or 2-cyanoethyl.  The polymeric number of the polysiloxanes is preferably above 10.  Examples are given for the preparation of various suitable polysiloxanes, and for the use thereof as additives in polyurethane preparations. The polysiloxanes act as foam stabilizers in the foaming mass prior to curing, leading to good pore structure, and preventing loss of gas.  The process of Specification 935,615 is specifically disclaimed.

Abstract: 520,123. Valves for hydraulic systems. RICE, J. H. Sept. 2, 1938, No. 25161/39. Divided out of 520,078, [Group XXX] [Class 69 (ii)] A valvedistributing gear for hydraulic systems, such as electro-hydraulic systems in which a constant delivery oil pump driven by an electric motor is used to convert rotary into reciprocatory motion, comprises piston valves 46, 47 slidable in cylinders 44, 45 and acting to control the supply of the pressure medium to outlet pipes 48, 49 which may direct the pressure fluid to primary and secondary. turns for operating conveyer mechanism as described in Specification 520,078, [Group XXX]. The valves 46, 47 are controlled by pistons 57, 58 in cylinders 55, 56 supplied with the pressure medium by a pilot valve 52, which is also a piston valve. In the position shown in Fig. 3 the pilot valve is set so that the pressure medium passes via a pilot passage 50 and inlet channel 53 to the cylinder 55. The piston 57 is thus raised at the same time the piston 58 drops under the action of gravity or of a lever 65 operated by the piston 57. The cylinder 56 is connected to exhaust. The flow of medium is thus cut off from the pipe 48 and opened to the pipe 49. On moving the valve 52 to the left the operation is reversed, and the flow to the pipe 49 is cut off and the flow to the pipe 48 opened. The inlet pipe is fitted with a control needle valve. The lever 65 may be extended and fitted with spring-controlled levers 70, 71 which operate levers 78, 79 respectively in their upward movement' only and the levers 78, 79 control valves of pumps, or other hydraulically actuated mechanisms operated by a piston controlled by the valve-distributing gear described.

Title: Improvements in or relating to secondary emission electron multipliers
IPC: H01J43/30
Filed: 1936-09-21
Abstract: 481,750. Electron multipliers and circuits therefor. GENERAL ELECTRIC CO., Ltd., and BLIGH, N. R. Sept. 21, 1936, No. 25631. [Classes 39 (i) and 40 (v)] Frequency-selective amplification is obtained in an electron-multiplier by inserting frequencydependent impedances between one or more of the emissive electrodes and the D.C. supply. As shown, the input, which may be a modulated carrier wave, is applied between the primary cathode 1 and a negative grid 2, and impedances in the form of series-resonant circuits 17, 18 and 171, 18<1>, or of a parallel-resonant circuit 20, 21, are inserted between the secondaryemission electrodes 4, 4<1>, 5 and the supply - potentiometer 10. High resistances 19, 19<1> shunt the series-tuned circuits. The tuned circuit 20, 21 is shunted by a diode rectifier 22 and a load resistance 23, the latter having a condenser 24 across its terminals. The cathode of the diode 22 is connected to a grid 26 which carries the signal voltage and is situated between the electrode 5 and the output anode 6. The last emissive electrode 5 may be divided into two sections 5, 51 of which the former has the smaller co-efficient of secondary emission, and varying voltages on 'the grid 26 then vary the relative strengths of the electron streams striking the respective sections. Voltages may be tapped off from sections of the selective impedances and applied to auxiliary electrodes such as the grid 26 or to the potential plates 7 ... 9. Demodulation may alternatively be effected by operating one of the stages on a curved part of its voltage-current characteristic. An accelerating grid 3 may be placed on the outer side of the control grid 2. Specifications 443,777, 469,477, and 469,488 are referred to.

Abstract: 964,907. Television. PHILCO CORPORATION. July 14, 1961 [July 14, 1960], No. 25677/61. Heading H4F. In a colour television receiver utilizing a N.T.S.C. type of signal and employing a beam indexing tube 18, an " ambiguous " index signal (i.e. a signal which although phase invariant in the presence of beam modulation corresponding to highly saturated colours is not necessarily indicative of beam position for a given colour) of frequency 3f, where f is the " writing " frequency, is produced by photoelectric means 27 and after amplification in 34 is converted to a frequency b in dividing means 35 and supplied to a heterodyne adder 36 together with a signal of sub-carrier frequency (derived in regenerator 38 from the " burst " signal output of receiver 10) to produce a signal which is then combined by subtractive heterodyne action in a mixer 37 with the chrominance sub-carrier (from receiver 10) to produce a colour writing signal of frequency f/2. This latter signal is then combined by subtractive heterodyne action with the 3/2f signal from amplifier 34 in a mixer 39 from which an unambiguous colour modulating signal of writing frequency f is derived and supplied to the modulating grid 19 of tube 18 together with the luminescence signal derived from receiver 10. With this arrangement the colour writing signal f supplied to grid 19 is free from objectionable phase errors since by the subtractive action of mixer 20, phase deviations of the signals in the channel 35, 36, 37 cancel those of the <3>/2f signal due to amplifier 34 and mixer 20. Specification 931,083 is referred to.

Patent GB-463051-A (GB)
Title: Improvements in and relating to tempering of glass sheets
IPC: C03B35/20
Filed: 1935-09-19
Abstract: 463,051. Tempering glass. PILKING- TON BROS., Ltd., and FORBES, L. J.-B. Sept. 19, 1935, No. 25983. [Class 56] Relates to apparatus for tempering curved glass sheets in which the sheets, suspended by tongs or the like from a supporting member, are bent to the desired shape after heating and before cooling. According to the invention, the tongs are suspended by a device which allows them to pivot freely and to move horizontally in two directions substantially at right-angles, so that no lateral or twisting force is exerted on the glass sheet at the point of suspension. The blowing frame, also, consists of groups of vertical jet tubes, and each group is so supported that it is adjustable in position to suit the curvature of the glass sheet. The tongs are suspended by blocks 2, Fig. 1, which can be clamped on a tubular supporting member 1. The block is provided with a pin 3 on which an arm 4 turns freely, and a member 5, which runs freely on the arm 4, has an horizontal lower end 7 having a depression 8 in which rests a pivot screw 9, Fig. 10, on a piece 10 that carries a tongs 11. The tongs can thus turn about the screw 9, it can move along the arm 4, and it can turn about the pin 3. The blocks 2 can be attached to rectangular frames 14,.15, Fig. 7, connected by pivot pins 16 and provided with horizontal end members 18 which slide through blocks 19 pivoted to the limbs of a frame 13. The articulated supporting members can be bent to any horizontal curvature to which the glass sheet is bent. The cooling device consists of groups of three vertical jet tubes 22, Fig. 9, connected to headers 24 which are pivoted at 25 to a pipe 26 provided with an air supply pipe 27. A bar 28 attached to the pipe slides through a block 29 which can be clamped on a tubular support 30. The position of the tubes 22 can thus be adjusted so that the whole of the jet orifices are equidistant from the surfaces of the bent glass sheet and the air jets are directed at rightangles to the glass. The blocks 29 can also be clamped to an articulated frame similar to the frame shown in Fig. 7.
