Abstract: 767,334 Vices. SIMPSON, J. R. June 30. 1955 [Aug. 5, 1954], No. 22730/54. Class 61 In a conformable jaw vice two sets of jaw leaves 10 are adapted to be clamped in the position dictated by the profile conformation of an object x to be held by means which cause frictional resistance against diplacement of the jaw leaves in excess of the pressure exerted by the vice's actuating crew 16, said means comprising in combination co-operating inclined surfaces 11b, 19a which are operable either independently or automatically in conjunction with the vice screw. Each set of leaves 10 is slidably packed in a rectangular housing 11. Springs 12 engage grooves 13 in the leaves and press each leaf individually towards 'the object x. The springs 12 are supported upon rods 14 and are tensioned against the underside of cover pieces 11a of housings 11. One housing may be fixed to a base plate 15 or both housings may be slidable under the action of a right and left hand screw threaded shaft 16 to which a tommy bar 16a is connected. When the object x is placed between the faces of leaves 10 and the vice closed, the leaves which are pressed furthest back by the part of greatest width of the object's profile contact the lip 17a of a pivotally disposed actuator member 17 which is under the influence of a spring 18. A wedge mem. ber 19 is linked to the actuator 17 by a stud 17b and rollers 20 are interposed between the parallel faces 19a, 11b of the wedge and housing respectively. As the vice is closed by the screw 16 the inclined faces 19a, 11b move in relation to one another and the friction between the leaves 10 increases. In a modification shown in Fig. 2 the friction between the leaves is produced by a primary member constituted by a cam 22 operable by a lever 22a. The lever 22a is mounted in the housing 11 and engages the wedge member 19. The leaves 10 may be formed with grooves 10a of wedge section engaged by ridges 10b of corresponding section (Fig. 3).

Abstract: 744,806. Regulating. S.U.CARBURETTER CO., Ltd. Aug. 5, 1954, No. 22738/54. Class 7(6) The output of a fuel injection pump 6 is controlled according to the temperature and pressure of the air in the induction pipe 2 by a capsule 16 in an enclosure 15 which is connected by a pipe 14 of relatively large cross-section to the throat of a. venturi 13 downstream of the throttle valve 11 and by a pipe 17 of relatively small cross-section to the induction pipe downstream of the venturi 13. The pump 6. which may be as described in Specifica-- tions 533,596 or 552,547 [both in Group XXVIII] and which feeds injection nozzles 9 situated adjacent the inlet ports 5, is first adjusted to provide a correct fuelair ratio when the engine is running at the speed at which the mass of air induced per cycle is a maximum. When the engine speed increases the increase in the richness of the fuel-air mixture, due. to a decrease in the volumetric efficiency of the engine, is compensated for by the increase in suction at the venturi throat 13 Which -reduces the pressure, in the chamber 15 and reduces the fuel: supply. At idling a throttling device 18, operated from the throttle valve control means 23 by a cam 22, restricts communication of the pipe 14 with the venturi 13, and over-richness of the mixture is prevented by producing a high suction in the' pipe 14 by means of a venturi 25 in a by-pass 24 around the throttle valve, the: suction at the venturi 25, which at idling is higher than that in the induction pipe 2, being transmitted to the pipe 14 through pipe 26 containing an adjustable restriction 27.
Patent GB-751737-A (GB)
Title: Process for the production of esters
Filed: 1953-08-18
Abstract: Esters of aminohydroxybenzoic acids, particularly p-aminosalicylic acid, are prepared by reacting the acid chloride of the corresponding thionylamino-hydroxy-benzoic acid with an alcohol or phenol to yield the ester of the thionylamino-hydroxy-benzoic acid, and thereafter converting the thionylamino group into the amino group by reaction with a substance having a reactive hydrogen atom.  A typical reaction may be shown as follows <FORM:0751737/IV(a)/1> Compounds containing a reactive hydrogen atom specified are water, hydrochloric acid, sulphuric acid, acetic acid, methanol, ethanol, propanol and isopropanol.  Alcohols and phenols specified are methyl, ethyl, n-propyl, isopropyl, n-butyl, tert.-butyl, hexyl, decyl and benzyl alcohols, cyclohexanol, ethylene and butylene chlorohydrins, ethanolamine, aminopropanols, b -diethylamino- or -dimethylamino-ethanol, phenol, resorcinol, nitrophenols and naphthols.  At least double the equimolecular amount of alcohol or phenol is preferred and the temperature is preferably kept below about 50 DEG  C throughout the reaction.  The reaction may be carried out in the presence of an inert solvent such as benzene, toluene, xylene, chlorobenzene, dioxane, and diethyl, diisopropyl, methylethyl, methylpropyl and propylbutyl ethers.  The solvent may be omitted and the acid chloride dissolved in an excess of the alcohol or phenol used.  Pyridine may be employed, both as a solvent and also to absorb the hydrogen chloride evolved in the reaction when non-basic alcohols are used.  When basic alcohols are used the hydrochloride of the ester is formed.  In examples: (1) diethylaminoethanol is dissolved in toluene and a solution of p-thionylamino-salicylic acid chloride in toluene is added with stirring and cooling, then moist gaseous hydrogen chloride is passed through the filtered reaction mixture and the hydrochloride of the b -diethylaminoethyl ester of p-aminosalicylic acid is separated; (2)-(4) the dimethylaminoethyl, phenyl and n-butyl esters of p-aminosalicylic acid are prepared.  p-Thionylamino-salicylic acid chloride is prepared by reacting p-aminosalicylic acid and/or anhydrous salt thereof with thionyl chloride in the presence of a diluent at a temperature below 100 DEG  C.  Specifications 722,795, 722,885 and 722,886 are referred to.
