Filed: 1972-11-09
Abstract: 1412014 Mounting steerable wheels BAYERISCHE MOTOREN WERKE AG 9 Nov 1972 [9 Nov 1971] 51695/72 Headings B7D and B7H In an independent suspension for a steered wheel of a motor vehicle a wheel carrier is either connected to a suspension arm by two coupling links 11, 12 (Fig. 3) which are connected to one another and to the wheel carrier 5 and the suspension arm 10 respectively by pure swivel joints having respective axes I, II and III, or a single coupling link 31 (Figs. 11, 12) is connected by pure swivel joints having respective axes I, II to the wheel carrier and to a suspension arm 29 which is so connected to the vehicle superstructure and to a link 28 extending generally longitudinally of the vehicle that the arm 29 can rotate about an axis III extending longitudinally thereof, the axes I, II, III being so disposed in the straight ahead position of the wheel 1 that the axis I extends longitudinally of the vehicle and the axes II, III are contained one above the other in a generally vertical transverse plane and intersect at a point 13 which forms a virtual pivot through which the swivel axis 6 of the wheel passes. The swivel axis 6 may thus be inclined to produce a small or negative steering roll radius r 3  without obstruction of the space within the wheel 1 for accommodating a brake. The joint having the swivel axis I extending longitudinally of the vehicle may alternatively be arranged between the two coupling links or between one coupling link and the suspension arm. The upper end of the wheel carrier is attached to a second suspension arm by a ball joint or by an arrangement similar to that connecting the carrier to the first arm, or the carrier may be integral with a telescopic strut. The wheel may be steered by rotating the suspension arm by means of steering mechanism acting on the arm.

Title: Reverse osmosis membranes
Inventor: FORBES FREDERICK
IPC: G01N13/00
Filed: 1968-11-01
Abstract: 1292961 Cellulose ester films INVERESK RESEARCH INTERNATIONAL 2 Feb 1970 [1 Nov 1968] 51961/68 Heading B5B [Also in Division B1] "Open-pore" reverse osmosis or ultrafiltration membranes are made by a process comprising:- (a) casting a film from a casting dope containing (i) a cellulose ester, (ii) an organic solvent for the cellulose ester, (iii) a swelling agent as component (ii), or as further component of the casting dope and (iv) if desired or necessary, a solvent for the swelling agent miscible with the organic solvent; (b) evaporating a portion of the organic solvent to form a membrane; and (c) treating the membrane with an aqueous solution of a surface-active agent in such a manner that the membrane absorbs the solution, and maintaining the membrane free from any heat-treatment that would reduce its porosity. The preferred cellulose ester is cellulose acetate which is preferably present in a proportion of from 10 to 75%, especially 10 to 20% by weight. Examples of swelling agents are zinc chloride, zinc bromide, zinc iodide, magnesium perchlorate and formamide. Preferred are zinc chloride, zinc bromide and zinc iodide and these may be used advantageously in concentrations up to 20% by weight. The acidity of the casting dope is preferably adjusted to avoid both hydrolysis of the zinc halide and saponification of the cellulose ester. Where a zinc halide is used, preferably in a concentration of at least 4% and advantageously at least 6%, the surfaceactive agent in step (c) may be omitted. Water is the preferred solvent for the swelling agent, but if a liquid swelling agent, miscible with the solvent for the cellulose ester is used, then it is possible to dispense with the solvent. The surface-active agent is preferably a detergent and is suitably present in the treatment solution in a concentration of up to 3% by weight, although higher concentrations may be used. Acetone is a preferred solvent for the cellulose ester. The dope may be cast into a flat film or a tubular one, with or without a support of a porous tube. The casting is suitably carried out at temperatures from 10 to 23 C. and the immersing solution is preferably at a temperature of between 0 and 30 C., particularly between 5 and 21 C.  The membranes produced by the process of the invention are such that partial fractionation of solutes of molecular weight less than 2000 may be achieved. Preferred membranes may be capable of fractionating solutes of molecular weight below 1000, even at times below 500.
