Abstract: 625,260. Lubricating. KIDDE CO., Ltd., W., and LAMBERT, G. March 13, 1946, No. 7857. [Class 12 (iii)] [Also in Group XXVI] In a self-lubricating reciprocating pump, a pair of flexible annular washer 11 are secured to the end faces of the piston head 10 with a radially disposed part thereof adjacent the end face and a continuation part extending away therefrom along the cylinder wall, the sealing members acting as fluid-pressed sliding seals on the inward stroke of their respective piston face ; the surface of the piston between the sealing members has a circumferential groove 17 which communicates through a radial hole 14 in the piston with a passage 13 in the piston rod 9 which at its remote end carries a tube 20 dipping into an oil sump 2. A wick 19 may be inserted in the tube 20. On the outward stroke of a piston face the sealing member falls away slightly to give a suction effect on the oil.

Title: Improvements relating to lubricating oils
IPC: C10M135/28
Filed: 1937-03-18
Abstract: A lubricating-oil consists of a mineral oil containing an oil-soluble oxidation inhibitor compound with an aromatic nucleus which has directly attached thereto both an inhibitor group, and a stabilizer group comprising an oxygen, sulphur, selenium or tellurium atom attached to the nucleus in ether form, to which has been added a metallo-organic compound of bismuth, tin, or antimony soluble in the oil.  The oxidation inhibitor and metallo-organic compound may each comprise ,01 to 1 per cent by weight of the oil, the amount of oxidation inhibitor being preferably greater than that of the metallo-organic compound.  Oxidation inhibitors specified are tertiarybutyl-4-tertiarybutyl-6 hydroxyphenyl thioether, tertiaryamyl - 4 tertiaryamyl - 6 hydroxyphenyl disulphide, di-(4 tertiarybutyl-6 hydroxyphenyl) thioether and 4-butoxy-2-amino naphthalene.  Suitable metallo-organic compounds are triphenyl bismuth, triphenyl tin iodide, trimethyl triphenyl distannane, tetra propyl tin, tetra isobutyl tin and triphenyl stibene.  Examples are given of mineral lubricating-oils mixed with di-(4 tertiarybutyl-6 hydroxyphenyl) thio ether and either triphenyl bismuth or triphenyl tin iodide. Specifications 398,222, 433,257, and 445,813 are referred to. According to the Specification as open to inspection under Sect. 91, the oxidation inhibitors comprise high boiling organic compounds soluble in mineral oils and having the formula R-Xn-R1, where R and R1 are aliphatic, cyclic, or mixed groups, or are or contain an inorganic group, X is a negative element of Group VI of the periodic table, and n is an integer, specified examples of such compounds being diamyltrisulphide, amyl alphaxanthogenacetic ethyl ester, and compounds of the type of <FORM:0495869/III/1> This subject-matter does not appear in the Specification as accepted.

Title: Improved method for preventing corrosion or contamination by hydrogen sulphide produced by the action of sulphate reducing bacteria
Filed: 1937-03-19
Abstract: The action of sulphate-reducing bacteria, which in the presence of sulphate and organic matter liberate hydrogen sulphide, is inhibited by means of a dyestuff of the 3 : 6 diaminoacridine group, for instance acriflavine, proflavine; 2 : 7 dimethyl-3 : 6 diaminoacridinium hydrochloride or 2 : 7 : 10 trimethyl-3 : 6 diaminoacridinium hydrochloride.  The dyestuff may be applied to concrete structures in contact with sewage, may be added to the water at the base of gas holders, may be applied to pipes laid in soil, for instance by impregnation of a fabric wrapping of the pipes, or may be added to liquid or solid media, such as to sewage, soil, sea water, estuarine water or the like, in contact with metal or concrete structures, such as articles used in storage or transport of petroleum products, pipes laid in soil, submarine cables in storage tanks, or condenser tubes using estuarine water in the cooling system.  Corrosion of the metal or concrete, or contamination of the gas is thus prevented.  A quantity of the dyestuff sufficient to maintain a concentration varying between 1 in 50,000 and 1 in 1,500,000, according to the degree of infection or other circumstances, is sufficient.ALSO:The action of sulphate-reducing bacteria, which in the presence of sulphate and organic matter liberate hydrogen sulphide, is inhibited by means of a dyestuff of the 3 : 6-diaminoacridine group, for instance acriflavine, proflavine; 2 : 7-dimethyl-3 : 6-diaminoacridinium hydrochloride or 2 : 7 : 10-trimethyl-3 : 6-diamino-acridinium hydrochloride.

Filed: 1931-03-18
Abstract: <PICT:0368531/III/1> A photographic flash-lamp comprising a closed transparent container containing materials capable of reacting with the production of light such as metal foil and oxygen is ignited by energy applied to the outside of the lamp.  Fig. 1 shows a lamp ignited by a stream of sparks 9 from the high tension electrode 8 of a Tesla transformer.  The lamp may be earthed through a metal sleeve 7 at its neck or by holding the lamp in the hand. Alternatively the ignition may be effected by igniting a pellet of readily inflammable material preferably lying against the interior of the container by conduction from a match flame or by concentrated heat or light rays. The ignition means described may be provided in addition to the standard electric ignition device described in Specification 324,578, [Class 75 (i), Burners &c.].

Abstract: 629,107. Aerials. RUST, N. M., and RAMSAY, J. F. March 19, 1946, No. 8544. [Class 40 (vii)] An electromagnetic horn comprises means for differently modifying the velocity of propagation over different paths from apex to aperture so as to compensate for the effects of the different lengths of the paths on phase distribution across the aperture. Fig. 1 shows a horn flared out only in a plane perpendicular to the plane of polarisation. Plates P divide the opening into wave-guide sections the lengths of which are made so as to increase the phase velocity most at the outer, and thus longer, paths from a apex to aperture. In Fig. 4, the horm is flared in both directions and the plates P are shaped so as to give greater correction along the outer paths in both directions. In Fig. 5, the correcting plates P are arranged in a rectangular extension X of the horn proper H. In all cases the difference in velocity produced in different parts of the beam may be effected by differences in length or spacing of the correcting plates, or a combination of both. Also the plates may extend partly in the extension and partly in the horn proper (Fig. 7, not shown). Partition plates may also be employed in folded horns or in " skew " or " part " horns which are cut through the longitudinal axis, the section plane lying along the ground surface (Figs. 9-12, not shown). Fig. 13 shows a biconical horn BC, energized by slots S and provided with peripheral phase-correcting plates P, those nearer the centre having a smaller radial length. Specification 629,151 is referred to.
