Title: Improvements relating to vehicle brake mechanism
IPC: B60T13/22
Filed: 1944-10-03
Abstract: 576,439. Brakes. AVELING-BARFORD, Ltd. and BRAMBLE, W. H. Oct. 3, 1944, No. 18888 [Class 103 (i)] A control element for a spring-applied fluidpressure released brake comprises a pair o: valves 15, 16 each having a co-axial plunger 20 25, separated therefrom by a spring 17, 22 and a rocking operating lever 31 connected to the pedal 33. The arrangement is such that the sum of the loads on the springs is substantially constant not withstanding that the load on each spring may vary from zero to a maximum. The springs 17, 2: of the valves 15, 16 are stressed to an exten which results in a partial brake application, i.e. the spring 17 is sufficiently compressed to hole the valve 15 closed against the pressure from the fluid admitted through the port 5, and the spring 22 is sufficiently relaxed to allow the brake cylinder pressure partly to vent past the valve 16 to the exhaust pipe 14. Further clockwise movement of the lever 31 still further compresses the spring 17 and still further releases the spring 22, thus permitting the ball valve 16 to lift to release the reduced brake cylinder pressure. The pedal 33 is connected by a cable or rod 32 associated with a compression spring 34 and a tension spring 37, to give a "feel" effect on the pedal.

Abstract: 535,290. Photographic projection printing apparatus. ZEISS IKON AKT.-GES. June 27; 1938, No. 19033. Convention date, July 30, 1937. [Class 98 (i)] An optical system for projection-printing apparatus comprises a light source, a condenser system, a projection objective, and two or more means for controlling the state of vibration of light which are relatively movable in order to vary continuously the ratio of the intensity of the light diffused by the negative or original to that directly transmitted by it in the light beam used for the image formation. As shown in Fig. 1, the system may comprise a clear glass lamp L, condenser K, negative holder N, projection objective O and two relatively rotatable polarizing filters, one F in the illuminating beam, and the other F<SP>1</SP> in the imageforming beam. The condenser K forms an image Ll of the lamp L in the diaphragm aperture of the objective O. If an opal lamp or an illuminated matt screen is used as source, the filter F is such that its image, formed by the condenser K, is located in the diaphragm aperture of the objective O, and approximately fills it ; or the two filters F, Fl are located close to the negative. In modifications, (1) the filters F, F<SP>1</SP> are fixed and a rotatable half-wave plate (or two quarter-wave plates) one stationary and the other rotatable) is arranged between them, and (2) the filter F is formed on the envelope of the lamp L, or on one of the elements of the condenser K. In a further modification, using an opal lamp or an illuminated matt screen, the filter F, Fig. 5, is close to the lamp and is surrounded by an annular filter F‹ having its plane of polarization perpendicular to that of F ; and the filter F<SP>1</SP> is disposed as shown, or between the objective O and the light-sensitive sheet P. In this form, an arrangement may be used in which the aperture of an intermediate condenser acts as a light source. Reference is made to the use of elliptically or circularly polarized light, and of devices employing doubly-refracting material. Specification 22671/38 as open to inspection under Sect. 91 is referred to.

Title: A process for the preparation of imidines and acylamidines and/or their tautomers
Filed: 1937-07-08
Abstract: 501,967. Conversion products of amidines; oils ; lubricants. ELKING- TON, H. D. (Naamlooze Vennootschap de Bataafsche Petroleum Maatschappij) July 8, 1937, No. 19046. Samples furnished. [Class 2 (iii)] [Also in Group III] Amidines containing a hydrocarbon substituent linked to a nitrogen atom are condensed with acylating or iminoacylating agents; an acylating agent is defined as a compound which introduces a carboxylic acid radicle into the molecule, and an iminoacylating agent is defined as a compound which introduces into the molecule a group RC(: NR<1>)-, where R and R<1> are alkyl, aryl or aralkyl groups. Specified acylating agents are carboxylic acids or their anhydrides or halides, or ketenes ; specified iminoacylating agents are imide chlorides and imino ethers. The products are amidines substituted by a carboxylic acid radicle or the corresponding products (termed " imidines ") in which the oxygen atom of the carboxylic acid radicle is replaced by a group : NR<1>. They may be used, as such or as their metal compounds, as (inter alia) agents for destroying noxious organisms, textile assistants, and as additions to motor fuels and lubricating agents. Examples are given in which (1) N-ethylacetamidine is condensed with butyryl chloride to yield a N-ethyl-N-butyrylacetamidine; a N-methyl-N-acetylbutyramidine, a N - allyl - N - butyrylbutyramidine, and a N- methyl-N-propionylacetamidine are similarly obtainable from the appropriate N-substituted amidine and carboxylic acid chloride ; (2) N-allylbutyramidine is condensed with pivalyl X-allylimide chloride to yield an imidine. Samples have been furnished under Sect. 2 (5), of products prepared as follows : (1) N-phenylbenzamidine is condensed with butyryl chloride ; (2) N-benzylacetamidine is condensed with butyryl chloride ; (3) N-ethylpivalylamidine is treated with ketene to yield a N-acetyl-N-ethytpivalylamidine ; (4) N-ethylhexahydrobenzamidine is condensed with butyryl chloride. The Provisional Specification covers the treatment of N-unsubstituted amidines, and states that R<1> in the formulµ above may be hydrogen. It includes also an example in which an imidine is prepared from butyramidine and pivalyl N-allylimide chloride. Pivalyl N-allylimide chloride is obtainable by converting pivalic acid into its chloride by reaction with phosphorus pentachloride or thionyl chloride, condensing the chloride with allylamine to yield pivalic acid allylamide, and treating the latter with phosphorus pentachloride to yield pivalic acid N-allylamide dichloride, which loses hydrogen chloride spontaneously to yield pivalyl N-allylimide chloride. N-Benzylacetamidine is obtainable from benzylamine and acetimino ethyl ether. N-Ethylpivalylamidine is obtainable from ethylamine and pivalyl imino ethyl ether. N-Ethylhexahydrobenzamidine is obtainable from ethylamine and hexahydrobenzimino ethyl ether.
