Patent GB-768225-A (GB)
Title: Improvements in or relating to the soldering of metals and flux compositions therefor
IPC: B23K35/36
Filed: 1953-02-04
Abstract: A soldering flux comprises stannous chloride and a pyrazoline hydrohalide obtainable by the reaction of an aldehyde or ketone with a hydrazine hydrohalide or with hydrazine and a hydrogen halide.  The hydrohalide is preferably the monohydrochloride or monohydrobromide and may be prepared from acetone, methyl ethyl ketone, diacetone alcohol, diethyl ketone or, less satisfactorily, mesityl oxide.  The proportions of stannous chloride and pyrazoline hydrohalides may each vary from 10-90 per cent.  The flux compositions are prepared by mixing the dry ingredients and are used in non-aqueous solvents such as methanol, ethanol, isopropanol or ethylene glycerol, or dispersed in solid carriers. The flux is applicable to the soldering of aluminum and its alloys to aluminium or to copper or brass, using Cd-Zn, Zn-Sn or Pb-Sn solders.  In an example, 5 grams of 3, 5, 5-trimethyl pyrazoline monohydrochloride and 5 grams of stannous chloride are dissolved in 20 c.c. absolute methanol.  Specification 763,439 is referred to.

Filed: 1922-02-03
Abstract: 177,148. Jabs, A. March 18, 1921 [Convention date]. Packing, metallic; packing, non - metallic; connected to source of high or low pressure; draining. -In packing of the type in which a number of packing-elements 10 slide in recesses 8 formed in supporting-rings 2, 3, and 4, contained in a stuffing- box casing 1 and surrounding a shaft 5, the force with which each segment is pressed on to the shaft is the comparatively small resultant pressure of a radially-acting spring 11 and the radial pressure of the fluid medium which is permitted into the recess, combined with the friction produced between one face of the segment and its housing due to the axially-acting spring 12 and the pressure of the medium on the opposite face. The fluid medium is either leakage from the pressure fluid, which leakage is led off by the ring 6 and conduit 7, or steam supplied through the same means when packing against vacuum. Any number of packing-rings 2, 3, 4 may be used, and in some cases the axially acting spring may be dispensed with.

Filed: 1928-02-06
Abstract: 285,033. Figaneau, G. P. Feb. 9, 1927, [Convention date]. Actuated or applied by speed regulators. -A servo - brake operating mechanism comprises a rotatable member which can be clutched to the driving shaft of a vehicle so as to drive a centrifugally operated device adapted to apply the brakes which are thus automatically released in the event of the rear wheels becoming locked. The device comprises a cylindrical member 1 mounted by ball-bearings 3 so as to be immovable axially, in a casing 4 and carrying one member of a clutch 13, 13<1> the other member of which is driven from the driving shaft of the vehicle. A shaft 5 slidable within the member 1 is connected by a link 7 to the brake operating shaft. A pair of members 8, 8<a> sldiable radially the one within the other and both in slots in the members 1, 5 each carry a mass 9, 9<a> and are provided with inclined surfaces in engagement with corresponding surfaces on plates 11, 11<a> which abut respectively on the ends of the slots in the members 1 and 5. Thus when the clutch 13 is thrown into engagement the radial movement of the members 8, 8<a> under centrifugal force effects an axial movement of the parts 11<a>, 5, 7 thus applying the brakes. If the rear wheels should cease to rotate., the members 8, 8<a> and these parts resume the original position under the influence of springs 10, 23 with consequent release of the brakes. A direct connection may be provided between the shaft of the pedal coutrolling the clutch 13 and the brake shaft to permit of the application of the brakes when the vehicle is stationary, such connection permits also of a light initial application of the brakes prior to the application by the servo-mechanism.

Patent GB-833616-A (GB)
Title: Preparation of alumina
IPC: B01J21/04
Filed: 1958-02-07
Abstract: An alumina, especially suitable for a catalyst support, having a pore diameter from 135 to 180 <\>fA and a pore volume from 0.9 to 120 c.c/gm., is prepared by hydrolysing an aluminium alcoholate at less than 40 DEG  F. with an aqueous medium containing ammonium carbonate, freshly prepared from ammonium hydroxide solution and carbon dioxide as dry ice, the solution having a pH above 7.  The resulting hydrous alumina slurry is aged, filtered and dried and the alumina is thereafter calcined at 400 DEG  to 1500 DEG  F.  The aqueous medium should be such that from 1 to 10 mols. of ammonia present as ammonium ions and from 1 to 10 mols. of free or combined carbon dioxide are provided per mol. of aluminium alcoholate, the carbon dioxide being at least equivalent to the ammonia and preferably in excess. According to an example, aluminium alcoholate was prepared by reacting pure aluminium metal with amyl alcohol in the presence of a hydrocarbon solvent using mercuric chloride as catalyst.  Ammonium hydroxide solution (28% NH3) were contacted with dry ice until the formation of white solid ceased at about 20 DEG  F. after which the solution was filtered.  The aluminium amylate-solvent solution was then sprayed on to the prepared ammonium carbonate solution and the mixture was seeded with small particles of dry ice.  The precipitated alumina was aged for 10 days at ambient conditions after which a stream of nitrogen was passed through the slurry. The slurry was dried at 250 DEG  C. to produce alpha alumina monohydrate which was subsequently calcined at 1100 DEG  F.  The gamma alumina so obtained may be composited with platinum by impregnation with chloroplatinic acid followed by drying and calcining to form a hydroforming catalyst.  Specification 663,128 is referred to.

Abstract: 548,179. Hooks; bundling; artificial limbs. PYROTENAX, Ltd., and LEWIS, J. G. March 26, 1941, No. 4065. [Class 89 (ii)] [Also in Groups. VI and XVII] Crane hooks and like lifting appliances adapted to grip a number of rods or like articles from a heap or stack, have a number of jointed members that form an extension of the point of the hook and can be curled up preferably to such position that the weight of the load gripped is taken wholly or mainly by the body of the hook. The device is applicable also for use in forming a compact bundle of wire, rods, tubes &c. from a loose stack and for operating the fingers of artificial hands. In one form the device comprises two chains of triangular links A', A<2>, A' and B', B', B<3>. The link A<1> is pivoted at D to the point of the hook C, at D<2> to the link B<1> and at D' to the link A<2>. The link B' is also pivoted to the hook at D<4> and at D' is pivoted to an actuating lever E pivoted to the hook at E<1>. A stop C<1> arrests the linkage in the straight position and a stop D' limits the curled position. The lever E may be spring loaded or weighted to cause it to return to the straight position when the lead is off the hook and the hook may be suspended by the linkage G, F, G' to cause the device to curl up as the load is applied. The links of the two chains may be duplicated and interleaved to improve the distribution of bending movement on the pins. The triangular plates may be replaced by sets of thin bars. In a modified form in which sets of links are interleaved slots are provided in the links to pass pins that require to move relatively to the links. The amount of angular motion may vary along the chains and the links may vary in size so that the device may have a curvature greater at the outer end than at the inner end or conversely.
