Title: Improved variable-speed power transmission mechanism for motor vehicles
IPC: F16H61/02
Filed: 1959-05-26
Abstract: 862,409. Variable-speed gear; friction clutches. GENERAL MOTORS CORPORATION. May 26, 1959 [June 9, 1958], No. 17896/59. Class 80 (2). [Also in Group XXXIV] A vehicle overdrive transmission between an input shaft 10 and output shaft 49 carrying the input pinion 11 of a sliding-gear synchromesh unit comprises a flywheel 16 coupled by a normally engaged main clutch 20 to the planet carrier 41 of an epicyclic gear unit 42, the sun pinion 51 of which is integral with a sleeve 52, and a drum 57 common to a brake 62 carried by a fixed housing 75, and a second clutch 61, the output member of which is splined to shaft 49. Brake 62 and clutch 61 are operated by pressure liquid acting upon annular pistons 78, 68, respectively, the effective area of the lefthand side of piston 68 being less than that of the right-hand side. Liquid delivered by a pump 91 may be fed under the control of a solenoid-actuated piston valve 107 to a pipe 111 communicating by a sleeve 122 with the right-hand side of brake piston 78, and also with a chamber 126 on the left-hand side of clutch piston 68. In addition, low-pressure oil for lubrication is supplied by pump 91 through a branch 95. pressure-regulating valve 96 and pipe 102 to an axial passage 102 through shaft 49, and through a branch 127 to a chamber 128 on the right-hand side of piston 68, from which it passes to clutch 61 through a passage 129 in the piston. For direct drive valve 107 is opened and the pressure liquid acts on piston 78 to release brake 62 against its engaging spring 83, and also passes into chamber 126 to engage clutch 61. For overdrive valve 107 is closed, cutting off the pressure liquid, so that brake 62 is engaged by spring 83, and the centrifugal pressures of the liquid in chambers 126, 128 acting on differential piston 68 bias the latter to the left to release clutch 61. Engagement of brake 62 holds sun pinion 51 stationary so that the drive from shaft 10 and flywheel 16 is transmitted through the annulus 47 to output shaft 49.

Title: Reaction products of polymers and polyisocyanates or polyisothiocyanates
Inventor: SEDDON ROBERT MAXWELL
IPC: C08K5/01
Filed: 1955-09-22
Abstract: The invention comprises a reaction product of a polyester, polyether, polyamide or polyesteramide and a polyisocyanate or polyisothiocyanate having incorporated therein a light mineral oil containing a minor proportion of aromatic hydrocarbons.  From 2,5% to 20% based on the weight of reaction product, of the said mineral oil is a suitable proportion.  The light mineral oils have an S.A.E. viscosity number of 5 to 30.  The preferred oils contain from 2,5% to 15% of aromatic hydrocarbons.  The oil is usually added with the starting materials of the reaction products, or it can also be added prior to the addition of the cross linking agent or in the final product prior to shaping.  Metal powders, such as aluminium powder can also be added.  Preferred reactants are polyesters, such as polyethylene adipate or sebacate and aromatic diisocyanates such as naphthalene, toluene, or p-phenylene diisocyanates.  Suitable cross-linking agents are tetra-(2-hydroxypropyl) ethylene diamine and a diglycol, such as butane-1,4-diol, either alone or in admixture, ethylene glycol or a polyhydroxy compound such as trimethylol propane.  A tertiary amine such as pyridine, triethylamine or piperidine may be added as a catalyst.  The products are useful for the manufacture of components of textile machinery, such as loom pickers, draw frame, ring frame and steam stretching rollers, anchor straps, lug straps, heald straps, spindle washers, spindle rod buffers, shuttles, linings of shuttles or shuttle boxes, linings of swells, rest pins for shuttles, picking bands, sleeves for picking sticks, bushes for Leno shaker mechanisms and pusher roller tyres.

Abstract: 861,465. Buckles. MARTIN, J. June 1, 1959 [June 5, 1958], No. 18062/58. Class 43 [Also in Group XXV] A quick release coupling comprises a plug 1 and a socket 2 intended for securement one to each of two members 24, 30 which are to be connected together thereby, the socket having a passage 9 therein for the reception of a tongue 6 on the plug and being formed with a channel 11 extending transversely of the passage, the channel having a pair of plug locking plungers 13 slidably mounted therein one on each side of the passage and urged in the direction of the latter by a resilient biasing means 19, each plunger being adapted in the locked position of the coupling to engage in a notch 8 formed in the tongue thereby to secure the latter against movement into or out of the socket and each of the plungers being provided with an actuating arm 12 situated transversely of the passage and extending outwardly of the socket on the side thereof remote from its associated plunger, the plungers thus being disengageable from the tongue by the application of inward pressure to the free outer ends of the actuating arms against the action of the biasing means. As shown the actuating arms are integral with the plungers and the biasing means are coiled springs trapped between the plungers 13 and fixed abutment blocks 16 which are rivetted in the channel so that they abut three walls of the channel but leave a space for the sliding passage of the push bars. The ends 21 of the plungers are chamfered and the leading corners 21 <SP>1</SP> of the tongue are similarly chamfered so that the plug can be pushed into the socket to automatically engage the plungers. The plug is provided with a rectangular opening 23 to receive the end of the member 24 and has a clamping bar 25 for fixing the member 24 to the plug. The clamping bar is of substantially cylindrical form and is mounted within the opening by means of transverse grooves in its end. The upper surface 26 of the bar 25 is serrated and its length is slightly greater than either diagonal.of the opening 23 but one of the arms 27 of the transverse groove at one end of the bar is slightly shortened and chamfered off so as to permit the interengagement of the bar within the rectangular movement or its disengagement when desired. A slot 29 is provided in the socket to receive the member 30. The plug is located in the socket by the sides 28 of a transverse groove at the upper end of the socket. Specification 796,877 is referred to.

Title: Improvements in or relating to purification of cellulosic materials
IPC: D21C5/00
Filed: 1945-07-19
Abstract: Material of the character of cotton linters containing non-cellulosic contaminants is suspended in water; the pH of the suspension is adjusted to 3.5 to 6.8, e.g. by addition of any acid (usually mineral) of dissociation constant greater than 3.2 X 10-2; and the material is cooked by steam under pressure; the treated material is then digested under pressure with an alkali digestion liquor followed if desired by an oxidising bleach.  The steam pressure for the pre-cooking of the suspension may be from about 75 to 135 lbs. per square inch and during the alkali digestion about 30 lbs. per square inch.  Owing to the variable amounts of inorganic ash in the raw linters, the addition of acid must be made after the linters are in suspension, and it follows that the amount of acid will vary, though usually it is of the order of a few thousandths of one per cent. Should the pH of the suspension be below the desired value, alkali such as caustic soda may be added to raise it above the desired value, and then acid added to adjust it to the desired value.  Small amounts of wetting agents such as turkey red oil, or sodium lauryl sulphate may be added to the material in the pre-cook treatment. In addition, about 0.01 to 0.16 per cent of such salts as ammonium nitrate may also be added.  In an example, the raw linters are suspended in ten times their weight of water, and the pH of the slurry adjusted to 4.7 by the addition of nitric acid.  Steam at 100 lbs. per square inch pressure is passed in for one hour (corresponding to a temperature of about 340 DEG  F.) and the linters washed.  They are then purified by digestion with 2.5 per cent caustic soda solution under steam pressure of 30 lbs. per square inch (about 275 DEG  F.) followed by multistage bleaching treatment with dilute aqueous solutions of available chlorine.  The purified linters may be acetylated or treated in any other manner according to known methods.
