Title: Flame retardant and/or self-extinguishing polymers and method for their production
IPC: C08K5/02
Filed: 1959-07-16
Abstract: Flame retardant compositions comprise a polymer derived from an alkenyl or substituted alkenyl aromatic monomer and a polybromocyclohexane having at least three bromine atoms, not more than three chlorine atoms and a total of six halogen atoms in the molecule, e.g. tribromotrichlorocyclohexane, tetrabromodichlorocyclohexane, hexabromocyclohexane or pentabromomonochlorocyclohexane.

Title: A control device for an automatic clutch with hydraulic action for automobile vehicles
IPC: F16D67/04
Filed: 1961-07-06
Abstract: 988,242. Clutch controls. ANDRE CITROEN S.A. July 6, 1961 [Aug. 3, 1960], No. 24512/61. Heading F2L. The control valve 5 of a piston- and-cylinder unit 2, 3 operating the release lever of a clutch 1 in accordance with engine speed through a centrifugal regulator 22 is normally subjected to a biasing spring 8 which, upon application of the brakes, is rendered inoperative to allow additional pressure liquid to be admitted to cylinder 3 to effect rapid clutch release. As shown, the valve 5 controls liquid inlet and exhaust passages 13, 14, and further passages 15, 16, respectively, communicating with cylinder 3 and a chamber 20 housing spring 8. The latter is normally compressed by an axial rod 10<SP>1</SP> projecting from a piston 10 held by a further spring 9 against the left hand end of a cylinder 10<SP>2</SP> communicating by a pipeline 19<SP>1</SP> with the vehicle brake actuator 19<SP>2</SP>. The regulator 22 is loaded by non-adjustable and adjustable springs 6, 7, respectively. Upon applying the brakes the pressure in line 19<SP>1</SP> moves piston 10 to the right against spring 9, thereby unloading spring 8 and allowing valve 5 to move to the right and admit additional pressure liquid to cylinder 3 for rapid release of the clutch.

Title: Purification of nickel carbonate
IPC: C22B23/00
Filed: 1965-06-10
Abstract: Impure NiCO3 is purified by dissolving it in aq ammoniacal (NH4)2CO3 soln. containing a soluble sulphide, separating the insoluble sulphides formed, and heating the soln. to precipitate purified NiCO3.  The soluble sulphide may be Na2S, NaHS or H2S, and may be added as not more than 3% of the Ni content of the soln.  The dissolving soln. may contain 50-150 g/l. NH3 and 25-75 g/l. CO2.  The purified NiCO3 soln. may be heated to 170-250 DEG  F. to ppt. 70-99% of Ni as NiCO3 at a rate of 0.2-2 g/l. of Ni per minute.  The crude NiCO3 may be obtained from an optionally pre-heated nickel-containing ammoniacal (NH4)2CO3 leach soln. by adding a sulphide to ppt. the bulk of the insoluble sulphides which are then separated, and ppting. crude NiCO3 by heating the soln.  The purified NiCO3 may be further purified by redissolving it in ammoniacal (NH4)2CO3 sulphide-containing soln. and reprecipitating by heating.  The NiCO3 may be calcined to give nickel oxide.  Na2S may be added to the NiCO3 before such calcination and the NiO formed on calcination then washed with H2O to remove all remaining sulphur as soluble Na-salts.

Title: Hinge mortising tool
IPC: B27F5/12
Filed: 1926-10-05
Abstract: 272,735. Waller, J. A. Oct. 5, 1926. Mortising. - In a hinge cutter the bottom and sides of the mortice are cut by adjustable knives 11, 58 respectively, which are carried by a bar 5 sliding in a support 73 and moved by handoperated rack - and - pinion gear. The pinion is mutilated to allow preliminary adjustment by sliding. The support 73 rests on the work, such as a door frame 79, by a lug 77. After the sliding cut an end-cutting knife 39<1> is depressed by a hand lever 65 against a spring 41. In a modified device for use with hard wood, the carrier for the knife 78 can be moved separately, by releasing a spring catch 23 which connects the knife 11 with the bar 5. The operation of the handle 82 then cuts the side walls alone, the spring 88 being compressed. The handle 82 is then returned, the catch 93 reconnects the knife 11, and a second operation of the handle moves both knives, effecting the cut shown in Fig. 9. The knife 39<1> is then operated as before.

Title: Adjusting device for a drum brake
IPC: F16D65/56
Filed: 1976-06-15
Abstract: 1509126 Adjusting drum brakes for wear SOC ANON DBA 15 June 1976 [23 June 1975 24 Oct 1975] 24790/76 Heading F2E Two spring-like friction couplings are provided, one for rotating one element of an extensible adjuster during brake application and the other for rotating the same element during brake release. The rotations may be in the same sense, so that the adjustment consists of their sum, or opposite senses so that net adjustment consists of their difference. As shown, the extensible element comprises one piston of a double-ended wheel cylinder and a screw member 56 which is grooved to receive one-turn springs 60, 68. The springs are wound in the same sense and each has a radially projecting end located in respective slots 64, 74 in a sleeve secured to the other piston 44. As shown in Fig. 4 the slots incline in opposite senses and at different angles relative to the longitudinal axis of the cylinder. Consequently when the pistons move apart to apply the brake, one spring tightens on the screw more than the other so forcing the screw to follow its movement and screw out of its piston. On brake release, friction is greater between the other spring and the screw so the latter is rotated in the opposite sense but through a smaller angle so that a net extension of the piston/screw is effected. In an alternative embodiment operating on the same principle (Figs. 8 and 9, not shown) the extensible member consists of a strut extending between the shoes. A further embodiment (Figs. 10-15) is identical with that described with reference to Figs. 9-14 of Specification 1,509,125.

Title: Apparatus for the rapid quenching of sparking between electrical conductors, produced by excessive voltage
IPC: H01T7/00
Filed: 1925-10-12
Abstract: 241,230. Buchholz, M. Oct. 11, 1924, [Convention date]. Protective arrangements.-An arc produced by excess voltage between a conductor c and an earthed conductor a is quenched by moving the conductors c, a relatively to each other in such a manner that the position of shortest distance between the conductors varies and the arc is thereby compelled to move along through the insulating medium in which the conductors are immersed. The conductor a may, for example, be a helix wound on a rotatable cylinder b. Fig. 2 shows a device in which the drum b is continuously rotated. The rotation of the drum here also causes by centrifugal action the circulation of oil through a filter i and the production of arcquenching jets of oil from holes m. A governor n moves the conductor c away from the drum should the speed fall off. The amount and nature of the arcing may also be ascertained by collecting the gases of decomposition in a receptacle o in which is a contact device r which operates at each arc or spark. According to modifications the bar mav rotate round the helix. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the provision of a weight w, Fig. 7, (Cancelled), for rotating the cylinder b, so long as an arc continues, an elec. tromagnetically controlled pawl and ratchet device s, t stopping the rotation when the arc is quenched. Modifications are also described in which there are two helices, in which the bar rotates about its own axis, in which the bar and helix are corrugated, and in which the conductors are hollow and oil cooled. This subjectmatter does not appear in the Specification as accepted.
