Title: Improvements in or relating to the production of resinous compositions
IPC: C08L61/24
Filed: 1937-08-07
Abstract: 500,357. Synthetic resin compositions. BAKELITE, Ltd. Aug. 7, 1937, No. 21792. Convention date, Aug. 18, 1936. [Class 2 (iii)] A resinous composition comprises a mixture of a heat-hardenable urea-aldehyde resin with finely-divided C-stage alkyd resin, the latter constituting 3 to 50 per cent by weight of the mixture. The alkyd resin is preferably prepared by repeated heating and grinding. 10-30 per cent by weight (calculated on the mixture) of alkyd resin may be added to a urea-aldehyde syrup or varnish and used for impregnating absorbent cellulosic material, e.g. paper or textiles, which may be formed into laminated panels by hot-pressing. The alkyd resin may be prepared by condensing a polyhydric alcohol, e.g. glycerol, sorbitol, or pentaerythritol, with a polybasic acid or anhydride, e.g. phthalic anhydride, succinic, malic, or maleic acid, to incipient gelation, then cooling in thin layers and repeatedly grinding and heating at 140‹ C. to a total of 100 to 120 hours' treatment. The resin may then be refluxed with an organic solvent, e.g. acetone, ethyl acetate, or ethyleneglycel mono- or di-ethyl ether; soaked in warm acetone; or boiled in water at atmospheric or higher pressure. The alkyd resin may be added to the urea-aldehyde resin by grinding them together or by stirring the alkyd resin into the liquid-stage, molten, or dissolved urea-aldehyde resin. In examples : (1) urea and formaldehyde are condensed in the presence of ammonium hydroxide to the viscous stage, and ethyl alcohol, ethyl lactate, alkyd resin prepared as above, lithopone, and carnauba wax added, the composition being used to coat sheets of alpha-cellulose paper, which are then dried, superimposed, and hot-pressed; (2) urea and formalin are condensed in the presence of ethylenediamine to a syrup, and ethyl alcohol and alkyd resin prepared as above are added, the composition being used as in example 1. The Specification as open to inspection under Sect. 91 refers also to mixtures of finely-divided C-stage alkyd resins in any proportions, with urea-aldehyde or phenol-aldehyde resins. In an example, a fusible resin is prepared by condensing phenol and formalin in the presence of barium hydroxide, and is incorporated with an alkyd resin prepared as above and treated with water under pressure at 140‹ C., either by adding the latter in alcoholic suspension during condensation or by grinding the resins together. The products may be moulded or cast and may be used for the preparation of dentures. This subject-matter does not appear in the Specification as accepted.

Title: Pedal arrangement for the control of the gas admission and the brakes in motor vehicles
IPC: B60K23/00
Filed: 1937-08-09
Abstract: 505,645. Controlling motor vehicles. GYGER, G. Aug. 9, 1937, No. 21897. Void. Convention date, Aug. 8, 1936. [Class 79 (v)] The accelerator and brake pedal 2 is pivoted at 7 on a boss 4 fixed to the brake lever shaft 3, so that when the pedal is depressed the lever 17 is rocked to apply the brakes, but when the pedal is moved laterally about the pivot 7 a roller 8 on the pedal bears against and rocks a lever 11 to control the throttle 19. A spring 12 urges the lever 11 towards the pedal to an extent limited by an adjustable stop 13, and the pedal is guided on one side by a fixed guide 14. The throttle can only be operated when the brake is released, since, when the pedal is depressed the roller 8 on the pedal moves out of contact with the lever 11. The pedal is formed with side flanges 16 to prevent the driver's foot from slipping laterally thereon.

Title: Improvements in or relating to explosive and ignitable substances
IPC: C06B25/04
Filed: 1954-07-27
Abstract: The invention comprises mono-ditetrazolesubstituted aromatic nitro-compounds having at least three nitro groups in each aromatic nucleus.  The compounds may be prepared by the reaction of alkali, alkaline-earth or heavy metal salts of ditetrazole with aromatic nitrocompounds having at least three nitro groups and at least one other polar group which is readily labile as a consequence of said three nitro groups.  The preferred ditetrazole salts are the sodium, barium and manganese salts.  Examples of aromatic nitro compounds are picryl chloride and tetranitraniline. The reaction may be effected in a solvent such as acetone in admixture with water.  The products are detonating explosives.  In examples: (1) the disodium salt of ditetrazole is introduced into a solution of picryl chloride in acetone and 10 per cent water and the mixture refluxed to give dipicryl ditetrazole; (2) the disodium salt of ditetrazole is reacted with tetranitraniline in acetone at room temperature.

Title: Improvements in or relating to lightning arresters
IPC: H01T1/16
Filed: 1930-07-22
Abstract: A lightning arrester comprises a porous block moulded under pressure from a mixture of particles of carborundum and grog (calcined kaolin clay) which may be impregnated with a trace of finely divided conducting material.  Metal or graphite particles may be used instead of carborundum, and zirconium silicate with ordinary clay or other binder is mentioned as an alternative to grog.  The proportions preferred are 75 per cent grog and 25 per cent carborundum by weight, but the carborundum content may vary between 15 and 35 per cent, depending on the purity of the grog and the shrinkage of the block on firing.  The proportion of metallic particles, when used instead of carborundum, is from 3 1/2 per cent, by volume, upwards.  Materials mentioned are brass, lead, copper, nickel, iron, aluminium, alloys such as ferro-silicon, ferro-manganese, ferro-chrome, ferro-tungsten and graphite.  Conducting oxides and sulphides of metals may be used. The manufacture of the blocks is described in detail in the Specification.

Abstract: 1,077,437. Regulating fluid-flow; fluidpressure servomotor systems. Y. M. PONSAR. May 18, 1966 [May 22, 1965; May 4, 1966], No. 22172/66. Headings G3H and G3P. Apparatus controlling the flow from an upstream liquid level 11 to a downstream liquid level 13 comprises a first gas chamber formed by a bell 16, extending into the downstream level, conduit 18, valve box 17, conduit 20 and a bell 19, which extends into the upstream level 11. The bell 16 has an orifice 22 for the flow of liquid between the levels which flow entrains gas. Gas is supplied through a pipe 26, valve 49 and valve 35 to a pipe 30 which is immersed in the liquid in the bell 19. A pipe 28 leads from the gas supply to a second gas chamber 25 to act on a piston 38 in opposition to the gas pressure in the first chamber acting on a piston face 37 of a valve 25 controlling the flow of air into the first gas chamber. A loading force acts on the piston 38 to oppose opening of the valve and this may be a pressure loading in chamber 41 or a weight connected to the piston by a rope passing over a pulley. With a constant loading on the piston 38, the pressure difference in the gas chambers are maintained constant and the flow of liquid through the orifice 22 is constant. The gas pressure in chamber 41 may be varied to vary the flow rate and this variation may be in response to changes in liquid level N so that the liquid flow is proportional to the level N. Valve 49 may also be controlled in response to liquid level N<SP>1</SP> to control the liquid flow.

Stacks of crates are conveyed in single file by continuously driven endless chains running in guides 2 from a stacker X through a holding station Y into a grouping station Z in which a group of four stacks is assembled for removal by a lift truck. In operation, the first stack of crates passes through the holding station Y and is guided by a pivoted deflector 17 on to a conveyer, comprising continuously driven endless chains in one of the guides 2 and in a guide 13, and engages a stop at the right of the station Z. The second stack follows the same path until it abuts the first stack in which position it operates a switch which causes supports 20x to raise the crates from the chains and also causes the deflector 17 to be moved to the dotted position. The next two crates are then brought to positions alongside the first two and supports 20 raise the second pair of crates from the chains. The four stacks are then removed, the supports 20, 20n are lowered automatically, a stop and lifter frame 7 at the holding station Y are lowered to release the following stacks of crates and the cycle is repeated. The system may be reversed in which case the deflector 17 is omitted, additional crate holding stops are provided as described with reference to Fig. 8 (not shown).
