Title: Device for operating the brakes of motor vehicles
IPC: B60T13/24
Filed: 1924-09-23
Abstract: 223,214. Godeau, F. L. Oct. 11, 1923, [Convention date]. Fluid-pressure; hand and foot actuations; force-transmitting mechanism. - In motorvehicles wherein the suction of the engine is utilized to apply the brakes, means is provided whereby air is admitted to the induction pipe from the brake apparatus only during the exhaustion of the brake cylinder. The initial movement of the brake pedal 1 rotates a plug 11 in a casing 10 carried by the lever 2, whereby the cylinder 23 is connected through pipe 25, plug passage 13, and pipe 28 to the induction pipe 29 of the engine, so that the brakes are applied by the movement of the piston 22 acting on the brake rods 4 through the piston rod 21 and lever 2, the communication between the cylinder 23 and pipe 29 being maintained by causing the pedal 1 to follow up the movement of the lever 2. Continued movement of the pedal, which is pivoted at 18 to the lever 2, gives also a direct application of the brakes. On release of the brakes, the parts are returned to the normal position shown by the return springs 8, 19, so that communication between the cylinder 23 and the pipe 29 is interrupted, and the cylinder is connected to atmosphere by the passage 14 and port 15. According to the Specification, as open to inspection under Sect. 91 (3) (a) the piston 22 is adapted to give a partial brake application only, the braking action being completed by direct pressure on the pedal; and the piston 22 may be actuated hv any available suction or pressure means. This subject-matter does not appear in the Specification as accepted.

Abstract: 334,223. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Feb. 23, 1929. Divided on 334,193. Alcohols are prepared by passing acetylene, or gaseous mixtures thereof with its homologues, together with steam over condensation catalysts and then conducting the products, without isolation, together with hydrogen over metallic hydrogenating catalysts. The condensation catalysts comprise compounds of aluminium or of metals, except arsenic, having a specific gravity above 4.4 and belonging to the second to the seventh groups of the periodic system; hydrogenating catalysts mentioned are metals of the iron group, copper and platinum. The hydrogenating cataeither in the same reaction vessel or in adjacent vessels. The hydrogen may, if desired, be introduced before the condensation stage; industrial gas mixtures containing hydrogen as well as acetylene hydrocarbons may be employed, such as coke oven gas or gas mixtures obtained by passing coke oven gas or methane and hydrogen through a high-tension electric arc. The condensation is generally carried out at a temperature of 250‹-500‹ C. and the hydrogenation at a lower temperature. According to the Example, acetylene and water vapour are passed over zinc oxide precipitated on silica gel, and the reaction product then mixed with hydrogen and passed over finely-divided nickel at a lower temperature. The condensed product mainly comprises ethyl alcohol. Specification 109,983 is referred to. The Provisional Specification describes the treatment nf any acetylenic hydrocarbon.

Abstract: 871,979. Hand grenades; fuzes. SUNDEN, K. H. July 7, 1959 [July 11, 1958], No. 23252/59. Class 9(1). A hand grenade is provided with a delay unit comprising a delay tube 12 and a detonator 11, which unit acts as a safety latch for a firing pin 17 and is movable by a spring 18 to free a slide 20, so that a spring 21 can move the slide until a primer 16 carried thereby is aligned with a pin 17 and a striker 41. The delay unit is held in the safe position by a mannually adjustable plate 23 with a central hole 24, which in one position allows the tube 12 to pass. The plate is engaged by a snap spring 26, which engages recesses therein corresponding to the safe and live positions. The unit is also held safe by a latch 28, pivoted on a shaft 27 in the frame and held by an outer lever 36 and tape 30, the latter being unwound by weights (not shown) fixed to its outer end. An additional safety means is a friction latch 33, held against the tube 12 by a percussion spring 34 which moves a cock 32 against a primer capsule 40 when the cock is released by the tape 30. When used exclusively as a percussion grenade, a latch blade is inserted in a recess 39 to disenage the friction latch 33 and prevent the cock 32 from firing the primer 40. For use as a time-release grenade, the plate 23 is set to prevent movement of the delay unit and no latch blade is inserted, and for use as a combined percussion and time-release grenade, the plate 23 is set to allow movement of the delay unit and no latch blade is inserted.

Title: Manufacture of dyestuffs of the fluorindine series
IPC: C09B17/06
Filed: 1934-08-13
Abstract: Fluorindine dyes of the following general formula <FORM:0442732/IV/1> are produced by oxidizing azophenines of the formula <FORM:0442732/IV/2> in which R1 is an aromatic radical containing a negative substituent, or is a polynuclear ring or a quinone nucleus, and R2 is an aromatic radical.  According to some of the examples, oxidation may take place so that either R1 or R2 forms part of the azine ring.  Oxidation is performed with mercuric oxide, lead peroxide, manganese dioxide or permanganate.  The products may be halogenated and/or sulphonated and the unsulphonated products are lakes, while the sulphonated are suitable for dyeing fibres.  The azophenines are obtained, according to the examples, by treating p-quinone-dianil with p-nitraniline, b -aminoanthraquinone, 3 - aminopyrene, 4 - chloro - 1-naphthylamine, p-aminobenzoic acid, and m-aminoacetophenone, or by treating p-aminodiphenyl with p-nitrosophenol, and the products are oxidized as described above, in all cases with lead peroxide.  The sulphonation of some of the products is described, and the bromination of the product obtained by oxidation of the azophenine from 3-aminopyrene and p-quinonedianil. The Specification as open to inspection under Sect. 91 describes also the oxidation of the azophenines from p - quinone dianil and m-nitraniline, from p-aminodiphenyl and hydroquinone, and from bis-a - and b -naphthyl-p-quinone-diimines, (which are obtained by the oxidation of the respective di-a - or b -naphthyl-p-phenylene diamines) and aminopyrene and aminodiphenylene dioxide respectively.
