Abstract: In a process for the production of sheet formations from compounds having several reactive hydrogen atoms and polyisocyanates, there is used as the polyisocyanate the reaction product of a polyhydric alcohol with at least one mol. of 1,3-diisopropyl benzene 4,6-diisocyanate per hydroxyl group in the polyhydric alcohol. Suitable polyhydric alcohols are 2-ethyl-hexane-1,3-diol, octadecane-1,12-diol, octa-9,10-decene -1,12-diol, castor oil, propylene glycol, butylene glycol, low polypropylene glycols, trimethylolpropane or hexane and hexane-1,2,6-triol.  The reaction products may contain masked isocyanate groups.  Polyesters, polyesteramides, polyethers, polythioethers and polyacetals can be used as the active hydrogen-containing compounds.  Pigments, metal powders, dyestuffs and plasticizers can be incorporated in the products. In typical examples (1) a reaction product with an isocyanate content of 7,6% is prepared from octa-9,10-decene-1,12-diol and the 1,3-diisopropylbenzene-4,6-diisocyanate and is mixed in toluene and white spirits solution with a polyhydroxy compound obtained from phthalic anhydride, castor oil and pentaerythritol. Films produced from the mixture dry in three hours at 80 DEG C. (5) a film of a reaction product of the polyisocyanate and castor oil, applied in white spirit, is left in a water-vapour atmosphere to cure.ALSO:1,3-Diisopropyl benzene 4,6-diisocyanate is obtained by phosgenation of the corresponding amine, produced by reduction of the dinitro compound.  The diisocyanate is reacted in excess with polyhydric alcohols and the NCO-containing products are used in the preparation of polyurethanes (see Group IV(a)).

Title: Improvements in or relating to power-transmission systems of vehicles
IPC: B60K17/24
Filed: 1946-09-02
Abstract: 626,487. Bearing supports. EVERNDEN, H. I. F., and HARDY, F. J. Sept. 2, 1946, No. 26398. [Class 12 (i)] In a motor vehicle transmission system, as described in Specification 597,137, in which the transmission shaft is in two parts connected by a universal joint, the shaft being supported adjacent said joint by a bearing mounted on the chassis or body by resilient means, providing a greater restraint to vertical movement than horizontal movement of the bearing, the resilient means comprise two cantilever springs located one on each side of a vertical plane through the bearing axis, and each secured to the chassis or body by one end, their other ends being connected to the bearing by two arms which project horizontally from either side of the bearing and which are rigidly secured to the latter at points lying in a horizontal plane substantially removed from that containing the shaft axis. The mounting allows the bearing to move in a plane normal to the shaft. The bearing housing 32 has rigidly secured to it two arms 33 projecting horizontally one on either side of the bearing and situated below the axis of the shaft 24. The outer end of each arm 33 is secured to one end of a rubber or like block 35, the other end of which is secured to a bracket 37 attached to the chassis 38, so that each block 35 extends horizontally from the bracket, is parallel to the bearing axis, and acts as a cantilever spring. The housing 32 is thus resiliently supported by the two blocks 35 so that it can move in any direction in a vertical plane normal to the axis of the bearing under the resilient restraint of the rubber in shear. A second pair of arms 39 projects from the housing 32 in the same horizontal plane as the arms 33, each arm 39 having at its free end a friction disc 40 movable over a friction plate formed by or provided on the bracket 37. The arms 33, 39 on each side of the housing are initially set towards one another, and are sprung apart to apply an endwise load on the blocks 35 when the mounting is assembled, so that the discs 40 are held resiliently against the friction plates to damp oscillations. Each block may be of such section in a vertical plane that it has greater stiffness in a vertical plane than in a horizontal one.

Patent GB-454691-A (GB)
Title: Improvements in the manufacture of films, threads, sheets or the like and the manufacture of resins therefor
IPC: C08F8/28
Filed: 1934-12-27
Abstract: Polyvinyl resins are manufactured by reacting together a polyvinyl ester (other than formate), a body containing an active carbonyl group capable of combining with free hydroxyl groups of a hydrolysis product of the polyvinyl ester, and water in the presence of a hydrolyzing and acetalizing catalyst and of a lower aliphatic acid as solvent.  Alternatively a hydrolysis product of a polyvinyl ester (other than formate) not previously acetalized is reacted with a carbonyl compound in the presence of an acetalizing catalyst and of a lower aliphatic acid as solvent, with or without water.  In both processes, the water present, if any, may be limited to not more than such amount as will permit of obtaining homogeneous reaction conditions such that the acetal reaction may attain or exceed 87 per cent of completion.  When the carbonyl compound is formaldehyde or a body yielding it, water may be present in an amount sufficiently large to secure the production of a substantially colourless resin, preferably in such an amount as to fulfil both the foregoing conditions.  The starting materials, catalysts, and other details of procedure may be as described in Specification 436,072.  The products may be worked up into films or threads as described in that Specification, or may be precipitated in fine granules by addition of water, the solvent being recovered in dilute form.  The products may be after-treated for the reduction of the percentage of free hydroxyl groups as described in the said Specification, and may be employed for the purposes enumerated therein.  In examples: (1) polyvinyl acetate of 15 centipoises viscosity is heated to 70 DEG  C. with water and paraformaldehyde in the presence of sulphuric acid and acetic acid; (2) polyvinyl acetate of 2,5 centipoises viscosity is heated to 70 DEG  C., with formalin solution in the presence of sulphuric acid and acetic acid; (3) polyvinyl acetate of 6 centipoises viscosity is treated as in (2); (4) polyvinyl acetate of 45 centipoises viscosity is similarly treated; (5) polyvinyl acetate of 150 centipoises viscosity is used; (6) polyvinyl acetate of 10 centipoises viscosity is heated with water, sulphuric acid and acetic acid, and the 68 per cent hydrolyzed product is reacted with paraformaldehyde in the same solution; (7) polyvinyl alcohol (obtained by hydrolysis of polyvinyl acetate of 6 centipoises viscosity) is heated to 70 DEG  C. with formalin solution in the presence of zinc chloride and acetic acid.  The formaldehyde or body yielding it may be replaced by acetaldehyde, propionaldehyde, butyraldehyde, benzaldehyde, furfural, crotonaldehyde or a ketone, and the polyvinyl acetate by the propionate or butyrate, in which case the acetic acid used as solvent is preferably replaced by propionic or butyric acid respectively.  Specification 351,082 also is referred to.

Class 80(1) [Also in Group XXII] A cam 19, Fig. 4, on the driving shaft of a rolling machine (see Group XXII), reciprocates through a bell-crank 21 and a controlling head 22 a rack 24, and the distance between the controlling head 22 and the rack 24 is automatically adjusted. The controlling head 22 carries a worm shaft 22a, Fig. 7, and a co-operating worm wheel integral with a rod 23 threaded into the rack 24. The worm shaft 22a is connected through opposed free wheel devices 22d to an arm 22c turning about an adjustable pivot 22l. Reciprocation of the controlling head 22 causes the arm 22c to rotate the worm shaft 22a by an amount dependent on the position of the pivot 22l on an arc 22n and in a direction determined by the setting of an arm 22h which is locked on one of the free-wheel devices 22d to render that device effective. Thus. the distance between the controlling head 22 and the rack 24 is progressively increased or decreased.
