Title: Improvements in and relating to change-over valves
IPC: F16K31/163
Filed: 1928-06-05
Abstract: 320,317. Hall, H., Turnbull, J., and White, W. A. June 5, 1928. Valves controlled by pilot or relay valves. - Relates to steam power. installations of the kind in which a set of reciprocating engines exhausts into a turbine, and in which the turbine is cut out when the reciprocating engine is reversed. The change-over valve 5 which diverts the exhaust to the condenser when the engine 2 is reversed is of the butterfly type, its movable member 5d being adapted to close on alternative faces as shown in Fig. 2. The valve spindle 5e is rocked by a steam actuated servo-motor 6 acting through rack and pinion gearing. When the main engine is reversed, an arm 20 on the reversing shaft 21 moves the pilot valve 10 of the servo-motor through rod 23, link 25, and arm 26. The pilot valve may also be moved by a hand operated lever 27, but the arrangement is such that this lever is effective only when the reciprocating engine is running ahead. The valve stem 16, Fig. 5, of the pilot valve is lifted by a lever 19 against the action of an adjustable spring 17 and carries a valve 13 which controls communication between a pressure steam pipe 10<a> and the servo-motor pipe 10<b> and also a piston valve 14 adapted to connect the pipe 10b with the condenser. In large installations two changeover valves may be provided.

Title: Improvements in carrying out gas reactions
IPC: C07C5/333
Filed: 1957-05-24
Abstract: In a process in which gas reactions are carried out with the aid of a fluidized catalyst, the catalyst is continuously circulated between the reactor (under reduced pressure) and a regenerator (at a higher pressure) wherein it is regenerated by oxygen-containing gas and heated; the system comprises auxiliary circulation by which the catalyst is conveyed from the regenerator to an intermediate container before passing to the reactor.  The means of conveyance is a gas, preferably the gas used in the reaction.  The following features are preferred: (a) the catalyst particle size is 1-300, particularly 20-100 microns; (b) the reactor pressure 0.05-0.5, particularly 0.1-0.3 atmos., and the regenerator pressure about 1-3 atmos.  The catalyst may be for example Al2O3 (activated by e.g. Cr2O3, MoO3, WO3, ZnO, BeO, Cu, Ni, Co, Pd or Pt) activated iron catalysts, phosphates, natural or synthetic activated silicates; in the example it is Al2O3 with 18% Cr2O3, particle size 50-100 m .  The following are gas reactions specified: formation of acetylene or ethylene by crockery, formation of styrene from ethylbenzene, isobutylene from isobutene, butylene and butadiene from butane (particularly), and vinyl chloride from dichloroethane.ALSO:Butadiene is produced from butane in a process utilizing a fluidized catalyst, the latter being continuously circulated between the reactor (at reduced pressure) and a regenerator (at higher pressure) wherein it is regenerated by oxygen-containing gas and heated; the system comprises auxiliary circulation by which the catalyst is conveyed from the regenerator to an intermediate container before passing to the reactor.

Title: Manufacture of para-aminobenzene-sulphonyl-allylguanidine
IPC: C07C311/64
Filed: 1942-11-30
Abstract: p-Aminobenzene-sulphonyl-allyl guanidine is prepared by reacting a benzene-sulphonic acid halide, containing in the para-position a substituent convertible to an amino group by hydrolysis or reduction, with allyl guanidine, and converting the substituent to an amino group.  The condensation may be effected in presence of water or an inert solvent such as ether, alcohol, dioxane, acetone, benzene, toluene, xylene, chlorbenzene, nitrobenzene or tetrachlorethane or a condensing agent or catalyst, for example an alkali, alkaline earth or organic base such as pyridine.  The substituent group may be acylamino, nitro, azo or azomethine which is converted to amino by hydrolysis or reduction in known manner.  In an example, p-acetylaminobenzene sulphochloride and caustic soda solution are added to allyl-guanidine hydrobromide, acetone and caustic soda solution at 5-10 DEG  C., the solution concentrated to separate the sulphonyl-allyl guanidine derivative which is dissolved in hydrochloric acid, stirred with charcoal, filtered, and the filtrate treated with caustic soda to precipitate p-aminobenzene-sulphonyl-allyl guanidine.  The Specification as open to inspection under Sect. 91 comprises also the preparation of p-aminobenzene-sulphonyl guanidines substituted in the guanidine residue by reacting a benzene sulphonic acid or a reactive derivative thereof, including, for example, an ester or anhydride, which contains in the para-position an amino group or a substituent convertible thereto, including, for example oxy, halogen or carboxy, with any substituted guanidine containing aliphatic, aromatic, alicyclic or heterocyclic residues, including hydrocarbon, oxyalkyl or acid residues.  Such compounds may be prepared by reacting S-alkyl-pseudo-thioureas with amines or the acyl compounds by reacting guanidine and an acid halide or anhydride.  When free sulphonic acids are used, the condensation may be effected with phosphorus pentachloride or oxychloride.  The Specification also comprises reacting an S-substituted benzene-sulphonyl-pseudo-thiourea, containing in para-position an amino group or group convertible thereto and prepared, for example, by condensing an S-substituted pseudo-thiourea-hydrohalide with a para-substituted benzene sulphon-halide, with ammonia or a compound containing an amino group (this forms the subject-matter of the divisional Specification 588,654) or with an amide such as acetamide, propionamide, acrylic, benzoic, mandelic or pyridine carboxylic acid amide or an alkali compound or substitution product thereof containing basic or acid groups.  An example describes the preparation of p-aminobenzenesulphonyl-dimethylguanidine by condensing p-acetylaminobenzene sulphochloride with unsym.-dimethylguanidine and hydrolysing the p - acetylamino derivative obtained.  This subject-matter does not appear in the Specification as accepted.

[Also in Division G2] Novel pyrazolinones of the formula in which Y represents an optionally substituted bivalent carbocyclic aromatic group, X represents -O-, -S-, -SO 2 -, -SO 2 N(R)- (where R is hydrogen or C 1-5  alkyl),-CONH-, or -N(alkyl)-, D represents a C 5-20  acyclic aliphatic hydrocarbon group, n is 1 or 2, A represents the group in which m = 1 or 2, each of R 1  and R 2  is hydrogen, alkyl or aryl, R 1  and R 2  both being hydrogen when m is 2, and Z represents the atoms required to complete a carbocyclic aromatic nucleus, and M is hydrogen, an alkali metal or an ammonium group, are prepared by acylating an appropriate 1-aryl-3-amino-2- pyrazolin-5-one with a reactive derivative of an acid HOOC-A-SO 3 H, e.g. the internal anhydride or pyridine salt. The pyrazolinones are colour couplers (see Division G2). The internal anhydride of o-sulphophenylacetic acid is obtained by reacting tolylsultone with KCN and hydrolysing the resultant potassium salt of o-sulphobemylcyanide to the potassium salt of o-sulphophenylacetic acid which yields the anhydride on treatment with thionyl chloride. The anhydride of o-carboxybenzyl sulphonic acid is obtained by boiling o-cyanobenzyl chloride with aqueous sodium sulphite and hydrolysing the resultant o-cyanobemylsulphonic acid sodium salt to o-carboxybenzyl sulphonic acid sodium salt which yields the anhydride on treatment with thionyl chloride.

Abstract: 1418414 A method of connecting a cable to a brush LE CARBONE-LORRAINE 10 April 1973 [10 April 1972] 17267/73 Heading H2E A method of connecting a metal cable to a brush 1 of an electrical machine involves making a seating recess 3 in a large face of the brush, introducing a metal part 7, which is then compressed so that it is held against the wall of 3 by elastic deformation to contact brush 1 electrically and then has the cable fixed to it. The metal part may be a spherical or part-spherical dome, the outer edge of which is a cylinder of diameter small enough to enter the base of 3, where it may be fixed by being partly flattened or as shown it is a disc 7. The brush 1 is placed on support 8 concentric with punch 9 in hole 2, of diameter half that of recess 3 and exceeding that of the cable, and connected axially to 9 by elastic member 10, which may be a stack of elastic washers. The disc 7 is squashed between punch 11 and the floor of 3 and then between punches 11 and 19 and expands against the wall of 3. The metal part may be of copper, silver, cupro alloy or a pseudo alloy made by compressing powders such as copper and silver and fritting, and its surface may be covered by a layer of say silver, tin, nickel or chromium.
