Title: Improvements in power actuators
IPC: B43K5/00
Filed: 1928-08-28
Abstract: 296,783. Bragg, C. S., and Kliresrath, V. W. Sept. 8, 1927, [Convention date]. Operating clutches. -A relay for operating clutches &c. comprises a cylinder containing a piston connected with the clutch &c. and adapted to be put under vacuum pressure by valve mechanism directly actuated by the operator against yielding retracting means the resistance of which varies to indicate to the operator the extent to which the clutch &c. has been moved. The piston 3 has a hollow rod 5 connected by an ear 10 to the part to be operated, and having an air inlet 11 with a dust collector 12. A chamber 13 on the piston contains an air inlet valve 14 which when seated leaves a spaco 13<a> always open to the air pressure. The valve slides on a rod 20 with the piston rod, and this valve rod carries an actuating collar 20a and a plate 26 between which and the valve springs 25 press, holding the valve normally closed. The rear of the cylinder communicates with the chamber 13 through an aperture 13<b>. The valve chamber contains also a vacuum or low pressure valve 16 adapted to close a passage 18 to the forward end of the cylinder. The valve is pressed by a spring 19 against a collar 20b on the valve rod, on which it slides, and is normally open. The valve rod is normally retracted by a spring 21. The front end of the cylinder is connected e.g. to the intake manifold 61, Fig. 1, of an engine, and when the valve 16 is open both sides of the piston are subject to vacuum. Pressure on the foot lever 88 first closes the valve 16 and gradually opens the valve 14, the pressure of the springs 25 being lessened, and the resistance felt by the operator thus increased. The piston is actuated by the air pressure and releases the clutch through a rod 78 and pivoted yoke 75, acting against a spring.

Title: Improvements in composite signalling systems such as combined telegraph and telephone systems
IPC: H04M11/06
Filed: 1928-08-29
Abstract: 322,487. Standard Telephones & Cables, Ltd., (Western Electric Co., Inc.). Aug. 29, 1928. Simultaneous telegraphy and telephony; phantom-circuit systems; two-way repeating systems. -In a system in which each of the conductors of a telephone pair 3, 4 is employed as a separate and simultaneous telegraph circuit, and in which the pair 3, 4 also forms one side of a phantom circuit, the telegraph instruments 1, 2 are associated with the conductors 15, 16, each wound with two equal windings. The inductance in each circuit comprises two windings in series, one on each core, and the directions of winding (9, 11 and 12 in one direction and 10 in the other) are such that currents in one telegraph circuit do not produce any effect on the other. On the other hand, a change in the inductance of one circuit due to the current flowing produces an equal change in the inductance of the other, so that the balancing of the conductors for phantom purposes is not affected. The cores may be enclosed in metallic shields to prevent flux leakage. A further double coil 8 drains any telegraph charges which accumulate on the condensers 19, 20. A similar double coil to that comprising scores 15,16 and windings 9 - - 12 is employed for bye-passing telegraph currents around a two-way telephone repeater.

April 3, 1933, No. 25278 /34. Convention date, Nov. 26, 1932. Divided out of and addition to 420,667 under which a Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 5, 1933. [Classes 39 (i) and 40 (iii)] In Braun tubes as described in the parent Specification in which an aperture in an electrode 3 is reproduced on the picture screen by an electron-optical system consisting of a cylinder 4 and an apertured plate 5, the potential of the cylinder 4 is varied in rhythm with the potential of the electrode 2 controlling the intensity of the ray primarily by space-charge control. Sharp focusing is thus retained even with ray currents above 1 milliamp. The potential variations on the electrodes 2, 4 are out of phase if the tube is filled with gas at a pressure of the order of 10-<3>mm. up to 5.10<-3>mm., but are in phase if the tube contains residual gas at very low pressure. These potential variations are inversely proportional to the sensitivity of the electrodes 2, 4. The variations on the electrode 4 may be as great as or greater than those on the electrode 2. The electrodes 2 .. 5 are biassed through resistances 1, 7 .. 10 and the intensity control 11 is applied through condensers 12, 14 and a potentiometer 13.

Patent GB-661737-A (GB)
Title: Liquid organo-polysiloxanes and compositions thereof
IPC: C08G77/00
Filed: 1949-10-04
Abstract: Liquid methyl polysiloxanes are made by hydrolyzing an ethereal solution of methyl halogenosilanes of the formula (CH3)nSiX4-n, where X is a halogen atom and having a CH3 : Si ratio of at most 1.4, subjecting the product to distillation under reduced pressure and separating fractions of a low degree of condensation which have a CH3:Si ratio of at most 1.4, contain 8 to 20 Si-atoms in their molecules, boil between 120 DEG  and 250 DEG  C. at a pressure of 8 mm. of mercury and gel at room temperature under the action of lead naphthenate.  The polysiloxanes may be mixed with fillers capable of insolubilizing the resins, e.g. magnesia, litharge, lead borate, and barium titanate containing lead naphthenate, to produce insoluble but thermoplastic masses which may be moulded and hardened by baking.  In examples: (1) a mixture of methyl-chlorosilanes, (CH3)nSiCl4-n, having a CH3:Si ratio of 1.25, is dissolved in ether and poured into water; the ether layer is separated and the resin obtained after removal of the ether is distilled under reduced pressure, as above, to yield the stable liquid polysiloxanes.  The crude resin obtained at the stage prior to distillation, thickens and gels on storage; (2) the liquid polysiloxane obtained as in example (1) is mixed with lead borate, and the gelled mass resulting after standing at room temperature for 24 hours is reduced to small pieces, charged into a mould and baked under pressure at 100 DEG  C. The polysiloxanes may be used for the impregnation of textile fabrics, paper, and cardboard, and for the formation of protective coatings, e.g. in the waterproofing of stonework.

Title: Process for the stabilization of cellulose ethers
IPC: C08K3/00
Filed: 1944-12-20
Abstract: Ethyl cellulose is stabilized against degradation by heat and oxygen by incorporating a material containing a metal of Group 1B of the Periodic Table in an amount equivalent to 0.0002 to 1 per cent of metal based on the weight of the ether.  In an example, films are cast from solutions of ethyl cellulose to which copper powder and various copper salts have been added, and then heated for 16 hours to 120 DEG  C. in air.  A table shows the percentage retention of viscosity of the ethyl cellulose.  In a second example, granular medium-viscosity ethyl cellulose is stirred with 30 per cent isopropyl alcohol and hydrated cupric acetate, whereby all the copper compound is absorbed.  In examples (3) ethyl cellulose is stirred with an aqueous solution of hydrated cupric acetate, and (4) ethyl cellulose is tumbled with ground hydrated cupric acetate.  In example (5), ethyl cellulose is mixed with aqueous isopropyl alcohol brought to pH 3.6 with glacial acetic acid, and then stirred with hydrated cupric acetate.  The previous example is repeated in examples (6) and (7), using pH 7.1 and 8.2, respectively.  In examples (8) and (9), ethyl cellulose is treated with dilute nitric acid and then stirred with 35 per cent isopropyl alcohol and cupric chloride, or cuprammonium hydroxide.  In place of copper, silver and its compounds, and gold may be used.

On placing within the container 34 another vial containing an unknown substance, oscillation again occurs only if the second substance includes the substance present in the first vial.
Patent GB-641643-A (GB)
Title: Improvements in or relating to the preparation of melamine
Filed: 1946-08-28
Abstract: A substance from which melamine is obtainable is heated in the presence of ammonia, and in the presence or absence of other gases such as nitrogen or carbon dioxide, under such conditions of temperature and raised pressure that the melamine is vaporized without decomposition and is withdrawn from the reaction vessel while still in the vapour phase.  The preferred starting material is dicyandiamide, but other materials which may be used are urea, cyanamide, guanylurea, cyanourea, biuret, guanidine, cyanuric acid, ammelide, ammeline, melam, melem and mellon.  The reaction temperature should be at least 350 DEG  C. and the partial pressure of the ammonia at least 750 lbs. per sq. inch, but the reaction may be effected at a temperature rising to above 600 DEG  C. and at a total pressure up to 5,000 lbs. per sq. inch.  Suitable combinations of conditions within these limits are specified.  As shown, the starting material, which may be a solution or suspension of dicyandiamide in liquid ammonia, is fed under pressure to a heated tube 1, from which the reaction products are withdrawn as vapour through a pressure-operated valve 6 into a collector 10 at atmospheric pressure, wherein melamine condenses as a powder without passing through an intermediate liquid <PICT:0641643/IV (b)/1> phase. The uncondensed gases pass through a filter 12 to the outlet 14.  The tube 1 need not be vertical but may be horizontal or inclined or may be a U-tube.  Specification 502,148 is referred to.

Abstract: 368,248. Cases for matches &c. KRAUSS, J., 37, Gartenstrasse, and LUCK, W., 35, Calwerstrasse, both in Stuttgart, Germany. Aug. 29, 1930, No. 25890. Convention date, Nov. 6, 1929. Void [Published under Sect. 91 of the Acts]. [Classes 18 and 94 (i).] A pocket match case or packet in which the matches are ignited as they are withdrawn has the matches attached to one wall of the packet by adhesive fastening means. As shown the packet is formed from a strip 1 of cardboard or stout paper folded to the shape shown in Fig. 5 to form a packet having a space 8 which may be used for cigarettes and like articles, and a narrow space containing the matches 3, which are attached by adhesive 4 to the strip 1. Strips 2 of ignition material are attached to the strip 1 so that when the strip is folded they lie on the inside of the space containing the matches. A ridge 7 causes the butt ends of the matches to stick out from the packet so that they may be easily grasped. A modified form of packet is obtained by folding a strip to which matches and ignition surfaces are attached about a fold line perpendicular to the matches, and in this form the two parts of the strip may be of unequal length, so that one is shorter than the matches while the other extends above the tops of the matches, or they may both be shorter than the matches which therefore project from the packet to the top edge of which a reinforcing strip may be fastened. The sides of the aperture in this construction may be slit to allow the edge portions of the packet to yield slightly when a match is extracted.
