Title: An improved manufacture of lubricants and lubricating compositions
IPC: C10G29/20
Filed: 1941-11-03
Abstract: 553,140. Lubricants. STANDARD OIL DEVELOPMENT CO. Nov. 3, 1941, No. 14131. Convention date, Oct. 1, 1940. [Class 91] A lubricating oil composition comprises a mixture of a waxy mineral lubricating oil, a small amount of a synthetic pour depressor, and a small amount of a natural substance extracted from a spent clay used for treating lubricating oil stock, which substance has the property of rendering the lubricating oil more sensitive to the action of the pour depressor. The " pour sensitizer " may be obtained from the spent clay by percolating therethrough at room temperature a naphtha solution of a part of the waxy oil or a waxy fraction to be used in the final blend and then removing the solvent by evaporation ; the material is not removed by naphtha alone which merely washes the residue free from oil. Alternatively, selective solvents may be used alone such as benzene, acetone, ether, isopropyl alcohol,. and ethylene dichloride, preferably hot but below 150-200 F. The solvent is removed by evaporation, and in this method of working the " pour sensitizer " is contained in the black viscous oil remaining which is then mixed with the waxy oil or a waxy fraction to be used in the final blend. The amount of extract added to the oil ranges from 0.01 to 1.0 per cent. by weight on the finished lubricating composition. The spent clay is one which has been used for treating crude cylinder oil stock or crude petroleum distillation bottoms, such as a Pennsylvania crude, a Colombia crude of the naphthenic base type, or a mixed base crude; the clay exemplified is Attapulgar clay. Any synthetic pour depressor may be compounded in the final composition, a Friedel-Crafts condensation product being preferred such as the product obtained from chlorinated paraffin wax, of 10 to 15 per cent. chlorine content, and naphthalene in the presence of anhydrous aluminium chloride. The preferred proportion ranges from 0.01 to 10.0 per cent. by weight on the finished lubricant. The waxy lubricating oil preferably comprises a blend of a bright stock and a neutral oil. Illustrative examples are given which show that whereas with the addition of a synthetic pour depressor alone to a typical lubricating oil blend, in the concentration of 0.1 per cent., reduces the pour point from 30 F. to 15 F., yet with the further addition of the " pour sensitizer," in the concentration above specified, the pour point is reduced to - 10 F. Specifications 479,479 and 511,207, and U.S.A. Specifications 2,018,758, 2,055,482, 2,087,682, 2,106,247, 2,115,823, 2,128,109, and 2,201,767 are referred to.

Abstract: 1,007,518. Hydro-pneumatic spring units. R. LEDUC. April 12, 1962, No. 14224/62. Heading F2S. A fluid-tight oleo-pneumatic spring for doors of hopper trucks serving for the transport by rail of coal comprises an untrued cylinder body 1, an oleo-pneumatic accumulator 2 screwed directly on to one end of the cylinder body through the intermediary of a union 3 threaded at both ends, the cylinder 1, accumulator 2, and the union 3 being made of steel, a trued bronze liner 9 disposed within the other end of the cylinder, a solid chromium-plated piston 10 having a machined wall slidably engaged within the liner 9 and penetrating within the cylinder 1 to compress the fluid trap of the accumulator 2 through the intermediary of the hydraulic fluid contained in the cylinder, a multiple fluid-tight and scraping packing disposed at the outer end of the liner, and a single filling orifice 20 formed at one end of the cylinder. The multiple packing comprises a U-shaped scraper 12, a felt ring 13 and a plurality of composite packings 14 each consisting of a friction ring 15 made of hard synthetic material and a flexible compression ring 16. The union 3, having a central hexagonal portion 4 with two circular grooves 5, 6 for the reception of toroidal packings 7, 8, is secured, as a force fit, into the accumulator 2 and the cylinder 1 in a fluidtight manner. In order to fill the cylinder with hydraulic fluid the filling orifice 20 is initially closed the piston being withdrawn from its fully telescoped position to establish a vacuum within the cylinder of approximately 7 m.m. of mercury, the vacuum being maintained for sufficient time to ensure that no infiltration of air takes place. The cylinder is then filled " in vacuo " in such a manner that the hydraulic fluid is almost completely deaerated. The orifice 20 is then closed by a force-fit screw plug 20, the hollow head of which is then filled with a suitable material to discourage subsequent unscrewing of the plug 21.
Patent GB-142377-A (GB)
Abstract: 142,377. Marks, E. C. R., (Acme Knitting Machine & Needle Co.). May 10, 1918. Circular machines.-Relates to the general arrangement of patterncontrolled driving gear, changemotion, and reduction gear for use during yarn changing, splicing, &c., in a machine designed to operate with a minimum of attention from the operative. A shaft 56 carrying the main pattern drum 63 is driven from the driving shaft 14 by a link 47 connecting a gear 45 with a crank-arm 48 which carries a segmental gear 80 meshing with a gear 81 on the shaft 14. The gear 81 reciprocates idly during rotary knitting and is locked to the shaft 14 for heel and toe knitting by a clutch hub 83 operated by a shift lever 85, the lower end of which engages the groove 86 of the drum 63. The arm 48 actuates a pattern chain sprocket 55 loose on the shaft 56 by a pawl and ratchet drive; the continually-moving pattern chain controls through its lugs 65 acting on a pivoted shield 64, another pawl 61 connected to the arm 48 for actuating the drum 63. A third pawl 75 playing on the edge of a guard-ring 69 of the drum may rotate the drum when notches 70 are presented, during the backward movement of the arm 48. The pattern mechanism is so designed that the ratchet wheel 63 normally moves one tcoth while the machine knits four rounds, but by the use of the pawl 75, a change in knitting can be effected when the machine has made only two rounds after a preceding change. When it is required to make a change after one round of knitting, the shaft 56 is driven forward by an eccentric 293 on the shaft 14, the lower end engaging screws 291 provided at the proper intervals on a wheel 285 which is fast on the shaft 56. The side of the wheel 285 carries an arm 283 with a cam-shaped end 286 which, as the shaft 56 rotates, passes over removable studs arranged in a circular track in a fixed plate 288. The rear end of the arm 283 engages a rod 281 slidable in a groove of the shaft 56 to operate the belt-shifting gear through intermediate con. nexions. When a low stud 287 engages the arm 283, a sliding belt-carrier block 258, Fig. 7, is moved against a spring to shift the belt from the fast pulley 20 to a slow pulley 19. When a high stud 289 is engaged, the block 258 is moved sufficiently far for a bar 271 moving with it, to raise a latch 274 by means of its roller 272 and throw the toggle members 266, 267 out of alinement. Springs 263 then shift a hanger 259 along rods 261 into the position for retaining the beltcarrier block 258 over the loose pulley 21. The machine can be turned by hand and the operating handle is provided with a ratchet so as to remain stationary while the machine is power driven, and is connectible at will to the power shaft by means of a withdrawable spring plunger. Specification 137,022 is referred to.

Filed: 1967-03-29
Abstract: To form recessed glass articles with finished, particularly polished, surfaces, a layer of relatively low fusing temperature glass is placed between two cylinders of relatively high fusing temperature glass aligned to give an end surface, the layer and cylinders heated to rigidly fix them together, the end surface then polished or otherwise finished, the whole then being reheated to a temperature between the fusing temperatures, and the layer therefore molten, and the cylinders displaced relative to one another, the cylinders then being cooled in their displaced position.  As disclosed in the manufacture of recessed discs for image intensifiers, glass cylinders 22, 26, 28 and 38 are disposed within a steel form 20, coated with a separating agent, with layers 24 and 30 of solder glass between the inner and outer pairs of cylinders and a plurality of wires 32 are spaced circumferentially between cylinders 26, 28. The innermost cylinder 38 has one end 40 sealed and a runber stopper 42 with air inlet 44 adjacent the other end which is sealed to the outermost cylinder 22 b sealing material 46 such as a quick-setting resin cement, having an inlet 48 through which a vacuum can be established between the cylinders.  The cylinders and layers are then passed through a zone heating furnace 50 with vacuum applied through inlet 48 and air under pressure through inlet 44 so that the cylinders are sealed together and pressed outwardly against the steel form 20. A glass rod (52) is then positioned to approximately fill the inner cylinder and heat is applied with pressure on the rod so that they are joined, with metallic leads 54 spaced round the <PICT:1122356/C1/1> <PICT:1122356/C1/2> rod to form electrodes.  Form 20 is normally then removed and the multicomponent cylinder sliced into discs 58 which are then polished. The discs 58 are then placed between male and female dies (62), (60) stepped to correspond with the solder glass layers 24, 30 and pressed in an oven to give three stepped layers 68, 70, 72.  Circles 71, 73 of conductive paint are then applied to ring 70 and disc 72 to provide electrical connections.  Two discs 58 may then be sealed together under vacuum at their outer rings 68, (68a) to enclose an electron multiplier array (76), the disc 72 having an inner application of photo-cathode material (78) and disc (72a) an application of a phosphor material (80) to give a completed image intensifier, leads being welded to the electrode wires 32, 54.
