Title: Improvements in diffusion bonding of super-alloy members
IPC: B23K1/19
Filed: 1970-03-18
Abstract: 1299983 Brazing GENERAL ELECTRIC CO 18 March 1970 [11 July 1969] 13006/70 Heading B3R [Also in Division C7] A method of bonding superalloy members based on Fe, Co, or Ni comprises providing a bonding material which corresponds with the composition of the superalloy member but includes 1-15% by weight of the total composition of a melting temperature depressant selected from the group B, Si, Mn, Cb, Ta or mixtures thereof, placing the bonding material in the gap of the intended joint the width of which does not exceed 0À02 inches, providing a high vacuum around the joint and applying heat to bring the material to a temperature in the range 1950-2250 F. for sufficient time to at least partially melt the bonding material the temperature being insufficient to melt or harmfully affect the structure of the superalloy members, and finally homogenizing the joint by applying heat in a further heating stage at a lower temperature and under non- oxidising conditions (preferably under vacuum) to produce interdiffusion between the superalloy members and the bonding material. The joint may be subjected to a third heating step at a temperature lower than the first and usually lower than the second to age the joint portion. The vacuum employed is no more than 10<SP>-3</SP>mm Hg. The bonding material may be applied as a slurry e.g. in an acrylic resin in toluene, which decomposes without residue on heating. The invention may be applied to the bonding of turbo blades to root or hub members. Specific alloys are referred to falling within the composition range:- 0À02-0À3% C; 8-25% Cr; 5-20% Co; 2-12% Mo; 0À3-7% Al; 0À5-6% Ti; up to 5% W; up to 2%V; up to 6% Cb and/or Ta; up to 0À2% Zr; up to 0À4% B; up to 25% Fe; balance Ni and incidental impurities.

IPC: G02B13/00
Abstract: 133,459. Smith, A. A. Oct. 12, 1919. Optical systems.-Photographic and like objectives are composed of two negative and two positive lenses separated by air spaces, and arranged in pairs in front of, and in rear of, the diaphragm; the negative lens of one pair is of a refractive index not greater than that of the adjacent positive lens, and the negative lens of the other pin is of substantial lower index than that of the adjacent positive lens, and also lower than that of the other negative; one of the pairs is of negative, or not appreciable positive, power; and at least one of the air spaces is bounded on one side by a plane surface. In a particular construction, a plano-convex lens of relatively high index is mounted near to a bi-concave lens of the same or lower index set on one side of the diaphragm, and a bi-eonvex lens of relatively high index is mounted near to a plano-concave or nearly plano-concave lens of lower index mounted on the other side of the diaphragm, the negative lenses being nearer to the diaphragm and one presenting its surface of deepest curvature and the other its surface of least curvature or plane surface thereto, and the first-named pair being of little or no optical power. In general, all the lenses are simple, but one or more may be of two glasses cemented together. Optical data for a construction comprising a plano-convex and a plano-concave lens are given.

Class 100(4) An auxiliary printing attachment for a record controlled printing machine has a printing member carrying a manually set symbol or symbols. Stationery 1, Fig. 1, is fed round a main platen 2 past a printing wheel 5 and between an auxiliary platen 3 and a printer 4. when a solenoid 16, Fig. 2, is energised an armature 17 rocks a lever 14 about 15 to depress arms 13 which push forward an arm 10 pivoted at 9 so that a stamp 8 hits the platen 3. Ink pad 18 is moved aside during printing by an abutment 19. Stamp 8 may be of rubber or type metal, in the latter case an ink ribbon may be used instead of an ink pad. The stamp may be replaced to change symbols or may carry type on movable bands or wheels. Energisation of the solenoid 16 is controlled by a machine function or by the stationery feed motion. The auxiliary printer may be mounted on the machine at any point relative to the main platen which suits the particular use required, e.g. signatures may be printed at the foot of a page simultaneously with the rest of the data, or the main platen and ink ribbon could be used for the auxiliary printer when symbols are required in the margin. Lateral movement of bracket 6, carrying plates 7 and solenoid 16, along platen 3 is also possible. Two or more stamps selectively operated may be used. Specification 704,764 is referred to.

Patent GB-630296-A (GB)
Title: Improvements in or relating to the manufacture of aminoguanidine compounds
IPC: C07C281/16
Filed: 1947-05-21
Abstract: Aminoguanidine sulphate is prepared by progressively introducing zinc into a suspension of nitroguanidine in an aqueous solution of ammonium sulphate until reduction to the stage of aminoguanidine sulphate is completed while maintaining the reaction temperature not above 30 DEG  C., and mechanically separating the oxidized zinc sludge formed during the reaction from the resulting solution of aminoguanidine sulphate.  The sulphate may be isolated from the solution but, preferably, the solution is treated with a soluble bicarbonate so as to precipitate the aminoguanidine as its bicarbonate; the bicarbonate may be formed free from contamination with soluble zinc compounds, by adding to the sludge-free solution ammonia and a soluble bicarbonate, the ammonia being used in amount at least sufficient to retain any soluble zinc products in solution on subsequent addition of the soluble bicarbonate.  The reduction is preferably effected with zinc powder at a temperature not above 25 DEG  C., using an amount of ammonium sulphate chemically approximately equivalent to that of the zinc which is itself present in small excess. Nitrosoguanidine is formed in an intermediate stage. Desirably an acid, such as sulphuric acid, is added progressively as reduction proceeds so as to maintain a pH of about 7.5.  The zinc sludge is filtered off and washed, the washings being used to make up fresh ammonium sulphate solutions.  Examples are given.

Abstract: 1,267,801. Desulphurizing hydrocarbons. GAS COUNCIL. 18 March, 1969 [21 March, 1968], No. 13738/68. Heading C5E. A process for desulphurizing hydrocarbon distillate oils comprises the stages (a) passing the vapour of the oil together with a hydrogenating gas comprising one or more oxides of carbon over a hydrodesulphurization catalyst and (b) passing the mixture of gases and vapours issuing from step (a) directly over a zinc oxide containing material which is capable of quantitatively absorbing the hydrogen sulphide produced and either quantitatively absorbing the carbonyl sulphide which may also be produced by reaction involving the carbon oxides or quantitatively convening carbonyl sulphide to hydrogen sulphide and absorbing the latter, the process being carried out such that substantially no carbonyl sulphide persists in the gas phase downstream of the region in which absorption of the hydrogen sulphide is complete. The hydrodesulphurization catalyst may be Mo, Ni, or Co sulphide, Mo-Ni on alumina, or Mo-Co on alumina. A third stage containing a zinc oxide-copper oxide composition may be added to remove final traces of sulphur; alternatively this composition may be used in stage (b). The hydrogenating gas may be a by-product from a steam reforming process.

Title: Manufacture of heterogeneous olefine polymers
IPC: C08F297/08
Filed: 1961-04-17
Abstract: Block polymers are made by the polymerization of C2-C18 vinyl group-containing olefines in the presence of a Ziegler-type catalyst by a process which involves polymerizing during 50 to 97% of the period a monomer which gives rise to a hard homopolymer having a melting point above 100 DEG C., and during the remainder of the period polymerizing a monomer or monomers which gives rise to a soft polymer having a second order transition point substantially below that of the selected hard homopolymer, and being either a homopolymer with so low a tendency to crystallize that if it is capable of crystallizing its crystalline melting point is less than 20 DEG C., or a copolymer.  The examples describe the polymerization in a liquid hydrocarbon medium and in the presence of a mixture of titanium trichloride and diethylaluminium monochloride or ethylaluminium sesquichloride of the following combinations of olefines: (1-2) ethylene followed by a mixture of ethylene and propylene, (3) ethylene followed by a mixture of ethylene and butene-1, and (4) a mixture of ethylene and propylene followed by ethylene.
