Patent GB-400189-A (GB)
Title: Improvements in or relating to the production of organic acids or esters thereof
IPC: C07C51/12
Filed: 1932-04-18
Abstract: A catalyst for the production of organic acids or their esters from aliphatic alcohols, esters or ethers and carbon monoxide is made by absorbing aqueous chromic acid in pumice or other support, drying at 125 DEG  C., and admixing with an adsorbent oxide such as silica gel. Other catalysts mentioned contain molybdic, tungstic, or uranic acid, and instead of silica gel another adsorbent oxide such as alumina gel or active charcoal may be used.  The catalytic apparatus, which may be operated at 700 atmospheres pressure, may be made of or lined with glass or may be made of steels containing a high proportion of molybdenum, cobalt, tungsten, chromium, manganese or nickel, or may be internally coated with chromium or silver.  Specifications 254,819, [Class 1 (i), Chemical processes &c.], and 283,989, [Class 2 (iii), Dyes &c.], are referred to.ALSO:Aliphatic acids or their esters are produced by passing a mixture of the vapour of an alcohol, ether, or ester and carbon monoxide over a catalyst comprising free chromic, molybdic, tungstic or uranic acid, that is to say the true acids such as H2CrO4 and not the corresponding oxides.  These acids may be mixed with an adsorbent oxide such as silica gel or alumina gel or active charcoal.  Instead of an alcohol such as methanol, substances or mixtures which form alcohols may be used.  Higher alcohols such as hexyl and cetyl alcohols may be employed, in which case if the alcohol is insoluble in water and it is desired to have water present, the alcohol and water may be introduced into the carbon monoxide as vapour or spray.  In examples (1) a mixture of 95 per cent carbon monoxide and 5 per cent methanol is passed at 250 DEG C. and 700 atmospheres pressure over a chromic acid catalyst made by absorbing aqueous chromic acid in pumice or other support, drying at 125 DEG  C. and admixing with an adsorbent oxide such as silica gel; (2) the same mixture is passed at 350 DEG  C. and 700 atmospheres pressure over a tungstic acid catalyst.  The catalytic apparatus may be made of or lined with glass or may be made of steels containing a high proportion of molybdenum, cobalt, tungsten, chromium, manganese or nickel, or may be internally coated with chromium or silver. Specifications 254,819 and 283,989, [both in Class 2 (iii), Dyes &c.], are referred to.

Title: Improvements in grinding wheel reciprocating mechanism
IPC: B24B47/04
Filed: 1952-05-02
Abstract: 699,226. Grinding machines. BRYANT CHUCKING GRINDER CO. May 2, 1952 [June 7, 1951], No. 11162/52. Class 60. A grinding machine includes a rotary workholder 1, Fig. 6, a grinding wheel 4 on a reciprocable support 3, means to reciprocate the support and a device movable from and to a position between the means and the support, the device having a mounting comprising a pair of members 26, 28, Fig. 1, yieldably held in alignment. An eccentric 20, Fig. 3, constitutes the means to reciprocate the support 3 which is connected by a bar 6 to one end of a lever 10 and urged to a position in which the grinding wheel 4 is clear of the work by a spring 7. The advance and retraction of the support 3 in relation to the work is effected by a cam (not shown) mounted on a shaft 13, Fig. 5, to cooperate with a follower 12 on the lever 10. A second cam 45 mounted on the same shaft periodically lifts a roller 40 which rocks the two members 26, 28, Fig. 1, against the action of a spring 50 and about a fixed pivot 29 to lower a bar 22 to a position between the eccentric 20 and a roller 24 journaled on the lever 10. The bar, which is spring-loaded and mounted for reciprocation in a sleeve 23, then transmits the motion of the eccentric to the support 3. If the space between the roller and eccentric is not sufficient to enable the bar to descend without shock, the member 26 yields about a pivot 27 and against the action of a spring 35 until the eccentric has rotated to a position in which the bar is able to descend. When the roller 40 falls under the action of the cam 45 to terminate the grinding operation, the bar 22 is retained in operative position by a stop 60 until a plate 67 reciprocated with the bar is at the rightward end of its travel, Fig. 3, when the bar is free of axial thrust and may be removed without shock. The plate 67 is adjustably clamped to a bracket 70 which is mounted on the bar 22 and fitted with a guide pin 72 riding in a lug 73. The stop is loaded by a leaf spring 61 which holds the bar in engagement with the eccentric as it descends. Specifications 678,188 and 678,202 are referred to:

Abstract: 356,095. Bearings. AKTIEBOLAGET NOMY, 2, Norrmalmstorg, Stockholm. April 15, 1931, No. 11189. Convention date, April 22, 1930. [Class 12 (i).] Bearing blocks and rolling members such as balls or rollers are arranged between the relatively movable elements of a bearing. Preferably the rolling members support the load when the elements are stationary or moving slowly and the blocks support substantially all the load during normal operation of the bearing. As shown two rows of blocks 2 supported by a ring 5 fixed to a shaft 4 have a spherical surface to co-operate with a bearing surface on a ring 3. Between the rows of blocks is a row of bearing rollers 7, a groove on the ring 5 serving as the inner race track. In a modification the periphery of the ring 5 is double conical so that the blocks 2 pivot about an axis inclined to the axis of the shaft. In another modification a single row of blocks only are used, a row of rolling members being arranged on each side thereof. If two rows of blocks are used they may be arranged in staggered formation. The invention may be applied to axial thrust bearings of the block type and to shafts which rotate in both directions. The blocks may be arranged so that in operation they are stationary.

Title: Gear gauging apparatus
Inventor: GATES THOMAS SINCLAIR
IPC: G01B5/20
Filed: 1958-04-11
Abstract: 846,796. Gear gauging and sorting apparatus. NATIONAL BROACH & MACHINE CO. April 11, 1958, No. 11591/58. Class 106 (2). Gear-gauging apparatus comprises a pair of master gears 34, 40 with their axes parallel and spaced so that both master gears mesh fully even with undersized work-gears passing therebetween, and means 53 for advancing a work-gear in the direction of its axis to a position in which its teeth enter to a substantial depth into the tooth spaces of both the master gears. One master gear 34 pivots on a lever 30, 32 about an axis 24 but does not revolve about its own axis; the other master gear 40 is rotated about its own axis by a rack and pinion 46, 44, the rack 46 being pneumatically operated by air applied to a cylinder 52. The workgears are fed along a shoot 53 by a vibrating feed device 54, the vibration ensuring that their teeth do mesh with the master gears 34, 40. When the gear is in position for gauging, it engages a pin 56 which actuates a switch LS7, the circuit then set up operating a solenoid which controls the supply of air to the cylinder 52, thus rotating the master gear 40 anticlockwise to pass the work-gear between the master gears. As the gear passes between them the master gear 34 pivots about the axis 24, and the arm 30 operates one or more limit switches LS1, LS2, LS3, according to the size of the workpiece. If the gear is within the required tolerance, it rolls over a surface 100, formed on a gate 88, and down into a shoot 82. Oversize gears are directed into a shoot 80, the gate 88 pivoting clockwise, and undersize gears fall into a shoot 84, a trap door 102 in the shoot 82 being opened in this case. The above operation is automatic and a circuit is described (not shown) which will perform this. A dial gauge 150 is used for adjusting the contacts of the switches LS1, LS2, LS3 prior to automatic gauging.

Abstract: Substituted sulphonamido compounds of therapeutic interest are formed by heating a benzenesulphonamide of the general formula <FORM:0595177/IV/1> or an alkali metal derivative thereof, with a compound, other than guanidine, of the type <FORM:0595177/IV/2> (X representing a chlorine or bromine atom, or an amino, or mono-acyl amino group; Y representing an alkyl, aryl or aralkyl radical, or an amino group; and R representing a hydrogen atom or alkyl, aryl or aralkyl radical), which may be generated in situ in the reaction-mixture by decomposing a salt thereof, e.g. the carbonate or sulphate, at a temperature generally within the approximate range 110 DEG  to 200 DEG  C., so as to eliminate a compound of the formula R.NH2.  The process may be effected in the presence of a solvent or diluent, e.g. ethylene glycol, of boiling-point not less than the temperature of reaction.  The reaction yields a compound of the general formula <FORM:0595177/IV/3> with elimination of the compound R.NH2, or may produce this derivative together with a compound of the general formula <FORM:0595177/IV/4> each of these types existing in their corresponding tautomeric forms.  Numerous examples are given. Ethylguanidine sulphate is prepared by refluxing methyl iso-thiourea sulphate, water and alcoholic ethylamine solution. o-4-Xylylguanidine sulphate is prepared by heating a well-ground mixture of o-4-xylidine and methyl iso-thiourea sulphate, triturating the cooled melt with 95 per cent ethyl alcohol and standing for 10-12 hours.  o-4-Xylylguanidine carbonate is prepared by treating with sodium hydroxide solution an aqueous solution of crude o-4-xylylguanidine sulphate and extracting with chloroform. Nonamidine hydrochloride is prepared by treating a mixture of nononitrile and dry ethyl alcohol with dry hydrogen chloride and then refrigerating for 3 days to crystallise noniminoethyl-ether hydrochloride; dry ethyl alcohol is stirred in, followed by dry alcoholic ammonia solution and the mixture maintained at 30-40 DEG C. for 36 hours, prior to evaporating the filtrate to dryness and recrystallizing the residue.  n-Octylguanidine sulphate is prepared by refluxing together methyl iso-thiourea sulphate, n-octylamine, water and ethyl alcohol until methyl mercaptan is no longer evolved.
