Title: Improvements in and relating to compositions for producing heat by combustion with air
IPC: C06C15/00
Filed: 1937-07-19
Abstract: Metals in the semi-pyrophoric form as described in Specification 433,174, [Group II], are used as the main combustible constituent of a composition for the production of heat by combustion with air, e.g. as a loose powder, a pressing with or without a binder, a coating on carriers or bodies to be heated, or a filling in hollow bodies. Metals such as aluminium, magnesium and zinc may be added to regulate the combustion speed or semi-pyrophoric metals of different reactivity may be used for this purpose.  To develop useful vapours, for instance for medical, perfumery or fumigating purposes, substances such as musk, resins, zinc chloride, balsams iodine or iodine compounds may be incorporated, e.g. with adsorption agents such as adsorption charcoal, and catalysts, e.g. manganese dioxide, may be included.  In one example a mixture of 460 parts semi-pyrophoric iron, 4 parts activated charcoal and 1 part iodine with 30 parts binder are formed as a coating on a glass rod.

Title: Cinematographic projector
IPC: G03B19/18
Filed: 1972-05-01
Abstract: 1330087 Turret lens mount PHILIPS ELECTRONIC ASSOCIATED INDUSTRIES Ltd 1 May 1972 [4 May 1971] 20101/72 Heading G2J In a cine projection a turret lens mount includes a spindle 8 and a sleeve 15 which inter-engage by means of a thread 12 and projection 16. A motor (not shown) directly drives the spindle 8 on the sleeve 15 so that a hub part 4 is advanced axially from a projection position (as shown) to a turret rotating position in which the motor rotates the hub part 4 until the required lens is located in the optical path, the motor is then reversed and the hub is returned axially to its projection position. As shown the motor powers sleeve 15 by means of shaft 22 and gears 20, 21 and the spindle 8 carries thread 12 and is connected to the hub part 4 by pin 9. Thus rotation of shaft 22 in a first direction causes spindle 8 to move to the right until stop ring 14 abuts the projections 16. Since further translation is now prevented the continued rotation of the shaft 22 rotates the turret until the required lens is aligned, when the motor reverses and the spindle 8 is translated back to the position shown. Slots 23, 24 in the hub part 4 (one corresponding to each lens on the turret) can receive locating pin 25 which prevents turret rotation except when ring 14 and projections 16 abut. A friction disc 28 is movable relative to the hub part 4 facilitates steady rotation. In alternative arrangements the sleeve 15 may be attached to the hub part 4 and the spindle 8 powered and/or the spindle 8 may carry projections and the sleeve threaded.

Title: A process for preparing pure alumina
IPC: C01F7/38
Filed: 1927-07-29
Abstract: 284,661. Zaidan Hojin Rikagaku Kenkyujo. Feb. 3, 1927, [Convention date]. Alumina prepared from clay or bauxite in an electric furnace and containing silicon, iron ferrosilicon or oxides of iron, is purified by treatment with chlorine or hydrochloric acid gas at a temperature about 200‹ C. Reducing agents are used when oxides of iron are present, for example, carbon may be added to the alumina, or carbon monoxide may be mixed with the gases. Volatile silicon tetrachloride and ferric chloride are removed, leaving the alumina in a loose brittle form which can be easily ground. The impure alumina is formed by heating clay and carbon in an electric furnace and separating the alumina from the bulk of the ferrosilicon formed by reduction. The mixture of clay and carbon may be first treated with coal gas at 900‹ C. to reduce the iron. The Specification as open to inspection under Sect. 91 (3) (a) describes also that, alumina prepared by wet processes and containing oxides of iron may be treated. This subject-matter does not appear in the Specification as accepted.

Title: Electrographic sheet
IPC: G03G15/00
Filed: 1970-04-28
Abstract: 1313143 Printing master MINNESOTA MINING & MFG CO 28 April 1970 [29 April 1969] 20434/70 Heading G2H [Also in Division H1] An electrographic recording member comprises a first layer adapted to provide an image pattern of conductive and non-conductive regions, a dielectric layer at least 6Á thick bonded to the first layer and a conductive layer bonded to the dielectric layer. The first layer is preferably photo-conductive and is exemplified by ZnO or TiO 2  dispersed in copoly styrene-butadiene and sensitized by Phosphine R, Setoflourine T and/or Rhodamine B, but other photo-conductors are specified. The dielectric layer may be polyethylene terephthalate, polypropylene, polyethylene, polystyrene, or polycarbonate but other materials are also exemplified. The conductive layer is preferably a vapour deposited layer of Al or Cu on the back of the dielectric layer or paper rendered conductive by a cationic resin, but other materials may be used. The conductive layer may be in the form of dots or lines or built up from a number of plys. Alternatively the first layer may be thermoconductive, for example hydrated Al 2 O 3  or SiO 2  in a binder. In an example a polyester film is coated with Cr and then an alcoholic aqueous dispersion of alumina. Materials that strongly supercool e.g. diphenylphathalate containing lithium salts or heat sensitive reactants that produce metallic species e.g. silver halides may also be used. Other materials specified for the first layer are semi-conductors or photo-insulators. The first layer may also be formed as a pattern of conductive materials corresponding to the pattern to be reproduced e.g. by painting or printing with a dispersion or graphite or silver.

Title: Improvements in boat sails
IPC: B63H9/067
Filed: 1962-05-28
Abstract: 965,494. Sails. P. M. LEMOIGNE. May 28, 1962 [June 8, 1961], No. 20469/62. Heading B7V. A sail comprises at least one slot, which is adapted to assume, under the effect of the wind, substantially the form of a nozzle capable of allowing a rapidly flowing stream of air to escape from the side of the sail which is not exposed to the wind. In Fig. 1 a spinnaker 1 is formed by a plurality of panels 4 connected by tapes 5. Certain of the panels are only joined on three sides to the tapes so that they comprise a free edge which, together with the edge of the adjacent fabric surface, can form a nozzle 4b. The escaping air is directed tangentially to the surface of the sail and in the case of the spinnaker 1 results in an upward resultant force causing the boat to lift. The invention may be applied to other sails, e.g. storm-jib, main and top sail. The panels may be arranged so that the nozzles are adjacent and direct air streams normal to the surface of the sail to prevent interaction between sails when more than one is used. The Specification also describes a method of manufacturing the sail.

Title: Improvements in or relating to hydraulic brakes, particularly for electric motors
IPC: H02K7/102
Filed: 1952-08-15
Abstract: 712,958. Fluid friction brakes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Aug. 15, 1952 [Aug. 18, 1951], No. 20568/52. Class 103(1) A brake having as its object the substantially instantaneous stoppage of an electric motor comprises a vaned rotor 1 rotated within a liquid filled casing 4 by a toothed wheel 10 on a shaft 9 driven by the motor. The rotor 1 turns within a cylindrical sheath 6, also immersed in the liquid, which is closed at one end by its tooth gear end 2 and at the other end by the casing 4. The sheath 6 has cut through it slits 7 which are of such a size that when the electric motor is running at its normal operational speed, substantially all the water is driven out of the sheath 6, air entering through a pipe 8. Under these conditions the device absorbs very little energy. As soon as the speed of the electric motor falls slightly liquid re-enters the sheath and by its resistance rapidly brakes the motor. Silicone oil is given as suitable braking fluid.

Title: Improvements in or relating to power traverse mechanism for lathes and like machine tools
IPC: B23Q5/34
Filed: 1943-12-09
Abstract: 574,889. Reverse gearing. DARLING & SELLERS, Ltd., and CATTLEY, A. Dec. 9, 1943, No. 20573. [Class 80 (ii)] [Also in Group XXII] In a lathe &c. having a fast power traverse for the saddle or like slide in addition to a slow power traverse and a hand traverse, the fast traverse operates through oppositely rotating clutches and the hand traverse is automatically disengaged when the fast traverse is engaged, the clutches and traversing gears being mounted in the apron of the saddle. The saddle 1 is traversed by a pinion (not shown) engaging a fixed rack, the pinion being driven by a gear K, secured to a hollow shaft H which is rotated, for the slow traverse, by a drop worm meshing with a worm-wheel J. Hand traverse is effected by a hand wheel W carrying an internally-toothed wheel V engaging teeth on a sleeve O carrying a gear O<1> driving the gear K through pinions M, N. Rapid traverse is derived from a bevel pinion D rotated by a gear-box (not shown), driving oppositelyrotating bevel gears E co-operating with clutches F. Either clutch may be expanded by a plunger G to drive the gear K and traverse the saddle in one direction or the other, both plungers coacting with cams on a rod' I axially slidable within the shaft H by a nut R acting thereon through a ball bearing S and screwing on a sleeve P fixed to the saddle 1. The nut R is rotated by a hand lever Z which also carries a plate T provided with cam grooves engaging plungers X contacting with the hand traversing gear V. When the lever Z is moved by hand in either direction from its neutral position to engage either of the clutches F, the plungers X are actuated by the grooves in the plate T to push the gear V out of mesh with the sleeve O, thus cutting out the hand traverse when the rapid traverse is engaged. In a modification, axial movement of the nut R rocks a yoked lever to displace the gear V and disengage the hand traverse and in a further modification, the hand wheel W is mounted in front of the lever Z on an axis parallel to that of the shaft H. Teeth on a portion of the periphery of the boss of lever Z mesh with teeth on a screwed sleeve rotatable in a fixed nut and carrying the ball bearing on the rod I so that rotation of the lever Z in one direction or the other will engage one of the clutches F, whilst cam grooves on the boss of the lever actuate pins to throw out a dog clutch connecting the hand wheel W to the traversing pinion meshing with the rack.
