Title: Improvements in or relating to thermo-setting resins
IPC: C08G12/38
Filed: 1944-03-01
Abstract: Thermosetting resins are prepared by condensing under heat formaldehyde with urea, thiourea, or cyanamide polymers, alone or in admixture, or by condensing methylol compounds derived from these substances, with or without the addition of one or more of these substances, as such, substantially in the absence of water but in the presence, as plasticiser, of one or more monoethers of polyhydric alcohols containing the group CH2OR, where R is aryl, aralkyl, or alkyl of not less than 4 C atoms, the total amount of such monoethers being not more than one-third molecule for each molecule of formaldehyde or for each equivalent methylol group employed in the condensation.  Monoethers specified are the mono-n-butyl, mono-phenyl, mono-cresyl and the monobenzyl ethers of glycerol. Condensation may be effected by fusion of the materials under heat, if desired with acid or alkaline condensing agents.  Fillers may be incorporated during condensation or subsequently, and the resin-forming components may be added to the plasticiser in portions. The plasticised resins may be used in hot-press moulding compositions together with fillers, lubricants, pigments and curing accelerators, or dissolved in water or aqueous solvents such as formalin or water-alcohol mixtures to give cold-or hot-setting adhesives in conjunction with hardening agents, fillers and extenders, or reacted with monohydric alcohols to etherify the residual methylol groups to give lacquer resins.  In examples: (1) dimethylol urea, thiourea, monobenzyl glyceryl ether and woodflour are compounded on a heated roll-mill, with lithopone and zinc stearate; (2) dimethylol urea is added in portions to a monocresyl glyceryl ether under heat; a glue for leather and wood is obtained by adding the product to hot water and may be set with phosphoric acid; (3) urea, melamine, paraformaldehyde, monobenzyl glyceryl ether, woodflour, lithopone and zinc stearate are compounded on hot rolls; (4) dimethylol urea is fused with monobenzyl glyceryl ether, and the product is dissolved in n-butyl alcohol containing formic acid.

Title: Improvements in or relating to television receivers
Inventor: CLEMENTS DESMOND REGINALD
IPC: H04N5/10
Filed: 1951-02-19
Abstract: 701,985. Pulse discriminating circuits. STANDARD TELEPHONES & CABLES, Ltd. Feb. 15, 1952 [Feb. 19, 1951], No. 3972/51. Class 40 (6) In a circuit for separating television line and frame synchronizing pulses the mixed pulses are applied to an input of a pentode valve to produce an output which is applied to a further valve feeding another input circuit of the pentode through an integrating circuit the arrangement being such that the combination of a frame pulse and an integrated frame pulse produces a second output from the pentode from which a frame synchronizing pulse is derived. Line synchronizing pulses are derived from the second valve. In the circuit shown the video signal is applied to grid of a pentode V1 biased so that only the synchronizing pulses (which are positive going) cause the valve to conduct. The output from the screen grid is applied to the grid of valve V2 which feeds its output through an integrating network R3, C3 to the suppressor grid of valve V1. This grid is normally biased to cut-off but the integrated frame pulses permit anode current to pass. The end of the first frame pulse at the control grid causes the anode current to be rapidly cut-off producing a sharp positive frame synchronizing pulse at the output capacitor C4. Line synchronizing pulses may be derived from the screen or anode of the second valve. According to the Provisional Specification the integrating circuit could be replaced by a delay line and the circuit arranged such that frame pulses on the control and suppressor grids but not line pulses overlap so that frame output pulses are produced.

Title: Improvements in electrical control systems for maintaining predetermined speed relationships between co-operating electric motors
IPC: H02P5/50
Filed: 1942-03-27
Abstract: 556,016. Automatic control systems for multimotor machines, and for dynamos. BRITISH THOMSON-HOUSTON CO., Ltd. March 27, 1942, No. 4084. Convention date, March 29, 1941. [Class 38 (iv)] Speed; voltage. - The individual speeds of driving motors in a sectionalized machine such as a paper making machine wherein changes take place in the length of web between sections, are controlled by tachometer generators which are opposed to a selected portion of the automatically regulated constant voltage of a main generator or exciter and the aforesaid portion may be adjustable to provide " draw " adjustment. Fig. 1 shows potentiometers 48, 54 in parallel with an adjustable portion of a potentiometer 28a across the constant voltage terminals of an exciter 17. The section motors 12, 13 have field windings 12a, 13a each in series with a resistance stack controlled by a regulator 52, 58. The actuating winding 52b of each regulator carries the output of a thermionic amplifier 53 grid controlled by the difference between a voltage rectified from a tachometer alternator 49, 55 and a voltage from the potentiometer 48, 54. The draw adjustment is obtained by moving contact 54a of the potentiometer. The potentiometer 28a is normally controlled and motor-driven to adjust the machine speed. The exciter field is regulated by a voltage controlled resistance stack in its field circuit ; the main generator has a similar regulator but its actuating coil is fed from an amplifier 26 similar to 53 and responsive to potential changes in the lower part of a potentiometer resistance 35 responsive to the difference between the voltage of the generator 14 and the portion of the exciter voltage determined by the adjustment of potentiometer 28a. The grid circuits of all amplifiers comprise a feed back coil on the associated regulator and the secondary winding of a stabilizing transformer 47 associated with the .controlled apparatus. In a modification the potentiometers 48, 54 are connected across the generator and permanent magnet D.C. tachometer generators are used ; in this case the generator is regulated in the same way as the exciter 17 and a manually controlled motor-driven rheostat adjusts the regulated voltage of the generator.

Title: Improvements in or relating to electromagnetic wave-guiding members and apparatus
IPC: H01P3/16
Filed: 1953-02-13
Abstract: 731,473. R.-F. power measurements. WESTERN ELECTRIC CO., Inc. Feb. 13, 1953 [March 1, 1952], No. 4097/53. Class 37. [Also in Group XL (b)] A standing-wave detector for measuring the degree of match between a wave-guide and a load in the millimetric range comprises a network of dielectric-strip guides of non-circular, e.g. oval or rectangular, cross-section (see Group XL (b)). Two such guides 26, 27, Fig. 2, may be held spaced from each other in a dielectric block 28 to form a directional coupler. A coupler 80, Fig. 7, of this kind is arranged to sample energy at different points on a dielectric strip guide 83, the block 84 being slidable upon the guide 83. A further coupler 90, similar to the coupler of Fig. 2, is arranged to have a 3 db. coupling factor so that energy in either of the arms 86, 87 is divided equally between the arms 88, 89. Under these circumstances a fraction of the energy proceeding from a source 81 is coupled into the arm 86 and a fraction of the energy reflected from a mismatched load 82 is coupled into the arm 87. Both these fractions are distributed equally between a matched load 91 and a detector 92. The detector will thus register a quantity proportional to the sum of the forward and reflected energies in the guide 83 and will give a series of maximum and minimum readings as the coupler 84 is moved along this guide. In order to calibrate the instrument the guide 83 is terminated by a completely reflecting termination and a suitable attenuator 94 incorporated in one of the arms 86, 87 to obtain zero readings for the minima. Specification 706,234, [Group XL (b)], is referred to.

Filed: 1932-02-13
Abstract: 401,332. Arc-rupturing in switches. LANGE, E., 73, Grossbeerenstrasse, Berlin. Feb. 13, 1932, No. 4309. [Class 38 (v).] The contacts of a switch are separated in a pressure chamber having an outlet formed in part by one of the contacts which is hollow, and cooling means are provided permanently within the pressure chamber, the outlet of which is closed by an automatic valve which opens at a predetermined rise in pressure. In Fig. 1 contacts 2, 3 separate in a pressure chamber 1 and a receptacle 7 containing CO2 is placed in the chamber 1 so that when the contacts separate the arc is extinguished by a stream of gas from the chamber 1 through the contact 3 and out through an adjustable spring loaded valve 5. The chamber 1 is surrounded by cork and a casing 6. Two points of break may be contained within a common pressure chamber. In Fig. 3 the chamber 1 is connected through a regulating valve 14 with a bottle 12 filled with liquid CO2. The bottle 12 may be inverted to allow solid CO2 to form in the chamber 1, the amount formed being regulated by an adjustable nozzle 11. The valve 5 may have an additional port leading to an absorption medium container which may be heated electrically to drive off gas into a condenser from which it is returned to the bottle 12 or a separate reservoir. In Fig. 5, the movable contact 2 carries a piston 16 working in the pressure chamber 1, solid CO2 being formed on the piston and at the bottom of the chamber 1 from liquid CO2 supplied through a pipe 18. Small holes 20, 21 in the piston 16 and contact 3 allow the pressure in the chamber 1 and under the valve 5 to equalise, the valve 5 having an additional port 5b connected to a collecting vessel. The increase of pressure produced by an arc formed when the switch is opened, moves the piston downwards to force cool gas through channels 17 on to the arc. The piston may keep the channels 17 closed until it has moved a certain distance, so that the subsequent gas blast is stronger.
