Title: Process for the manufacture of rubber pastes
IPC: C08L7/00
Filed: 1929-02-04
Abstract: 305,490. I. G. Farbenindustrie Akt.- Ges. Feb. 3, 1928, [Convention date]. Emulsions, making.-A reversible rubber paste which can be homogeneously mixed with fillers, vulcanizing agents, and the like, is prepared from natural latex, the latex of synthetic rubber, or a latex-like substance or mixture by treatment with a water-soluble cellulose ether or a solution thereof, heating to produce a precipitate, and separating the latter from water. On heating the cellulose ether is precipitated in gelatinous form carrying with it the rubber particles, and water is largely removed by means such as clarification, filtration, pressing or centrifuging. The paste may be used in place of latex for all purposes, such as painting and adhesive purposes, and can be diluted to a milk preferably in the presence of protective colloids. It is desirable to remove the emulsifying agent wholly or partially from synthetic rubber emulsions before the concentration process. In one example, 100 kgs. of 20 per cent ammonia-preserved natural latex are mixed with 2 kgs. of a cellulose methylether at 15‹ C., heated to 55‹ C., and the precipitate extracted in a bag on a heated centrifuge. The product is stated to contain upwards of 50 per cent rubber in a short time. In another example 50 kgs. of latex obtained by the polymerization of isoprene with an aqueous solution of Turkey red oil and sodium phosphate are mixed at 15‹ C. with 15 kgs. of a 10 per cent solution of trimethyl cellulose;'after standing for some hours at ordinary temperatures, when two layers are formed, the upper aqueous layer of rubber-free liquid can be drawn off, the latex then being heated to 40‹-60‹ C., and the paste extracted as before.

Filed: 1942-03-24
Abstract: 556,278. Bricks. METHVEN, F. D. March 24, 1942, No. 3915.

Title: Hat pouncing machine
IPC: A42C1/08
Filed: 1936-02-08
Abstract: 462,413. Hydraulic machines. DORAN BROS. Inc. Feb. 8, 1936, No. 3927. Convention date, Feb. 9, 1935. [Class 69 (ii)] [Also in Group VII] In a hat-finishing machine, hydraulic mechanism effects relative movement between the hat and tool axially of the hat and radially of the top portion thereof. The piston rod 27 of a cylinder 9 traverses the block axially. A second cylinder 7, has a piston rod which traverses the tool about the end portion of the block. A pump 6, Fig. 10, draws oil from a reservoir and delivers it to a pressure regulating valve 49 and thence to a speed control valve 53 and thence to a direction control valve 55. This valve has a high pressure inlet 55a, Fig. 11, a pipe 55b leading back to the oil reservoir, pipes 56, 58 leading, respectively, to the cylinders 7, 9, and a plunger 57 urged upwardly by a spring 60. The right-hand ends of the cylinders 7, 9 are connected by crossed pipes 70, 71, Fig. 10. In operation, the plunger 57 and the pistons being in the positions shown, pressure fluid passes from the pipe 55a to the.pipe 56 to urge the piston 63 to the right. Oil from the righthand side of the piston passes by the pipe 70 through the left side of the cylinder 9, to the port 58, passage 59, Fig. 11, and by the pipe 55b back to the oil reservoir. When the piston 63 reaches the right-hand end of its stroke, high pressure oil passes by the pipe 71 to move the piston 33 to the left-hand end of its stroke. The reverse action results when the valve is in its upper position, so that a complete cycle is, first, a semicircular movement of the tool about the tip of the hat, followed by a traverse of the hat block to the left, then, after reversal of the valve, a return of the hat block to the right, followed by a semicircular return swing of the tool. A handle actuates a plunger to depress the valve 57 at the start of the cycle, and this handle may have a lug engaging a pin on the clutch lever so that the clutch is engaged as the valve is depressed. A second cam co-operates with a roll on a lever controlling a plunger 176 in line with a valve stem 177b, Fig. 12, controlling the rate of flow of pressure oil to the valve 57. This cam is carried on the piston rod 73, and increases the speed of swing of the tool over the tip of the hat.

Abstract: 638,244. Reflectors for domestic heating installations. BAINES, R. Feb. 11, 1948, No. 4058. Addition to 606,164. [Classes 75 (ii) and 126] A domestic heating installation according to the parent Specification is provided with a radiant heat reflector which is adjustable to vary the direction and dispersion of heat radiation. The reflector, Fig. 1, may comprise a curved portion 5 placed behind the fire and provided with side cheeks 1, and horizontal pivots 6 at its upper edge. Alternatively pivots may be provided so that angular adjustment is permitted about horizontal axes through the middle, Fig. 2 (not shown) or lower edge, Fig. 3 (not shown) of the reflector. The curved portion of the reflector, Fig. 1, may be formed in two parts, the upper 5 of which reflects heat into the room, the lower 4 reflecting heat from one part of the fire to another. Corrugations, Fig. 2 (not shown) may be provided on this lower part 4 or over all the curved portions of the reflector. The portion of the reflector behind the fire may be plane, Fig. 4 (not shown) in which case it is provided with curved side cheeks and is pivoted about its upper edge or it may be bowl-like, Fig. 3 (not shown). The back portion of the reflector 18, Fig. 7, may be flexible so that its curvature may be altered by the action of a cam 27 or other means, maximum curvature being produced when the reflector 18 bears against fixed profile members 21 arranged behind it. Alternatively the curvature of a flexible reflector fixed at the lower edge, Fig. 8 (not shown) may be reduced by the application of pressure by pivoted profile members.

Title: Improvements in machines for parting off
IPC: B23B5/14
Filed: 1925-02-14
Abstract: 229,339. Romahn, J. Feb. 15, 1924, [Convention date]. Turning.-In a rotary tool-head for cutting-off and like operations, radially-arranged tools are moved forward during the cutting operation, and are subsequently withdrawn at high speed by means of friction gearing operated by the continuously-driven cutter-head. The head is driven by the hollow shaft 2, and is provided with tool holders 4 which are actuated by a scroll-plate 6 having a toothed rim 8. To feed the tools during operation, the scroll is driven at a higher speed than the sha.ft 2 from a wheel 13 through a pinion 12, clutch 11, and pinion 9 engaging the rim 8. On completion of the cut, the clutch 11 is disengaged by a lever 21, and further movement of this lever operates a second lever 22 to engage a friction roller 24 carried by a bar 23 with an annular groove formed between the shaft 2 and a member 26 secured to the scroll plate. A high speed return movement is thus imparted to the scroll plate to cause the quick return of the tools. In a modification. Fig. 6, the scroll plate is provided with internal teeth engaging a series of pinions 29 (only one being shown) on shafts 30 which actuate the tool-holders through wormgearing 32, inclined shafts 33, and worms 34. In a further modification, Fig. 10, the shafts 33 carry screws 36 engaging non-rotating nuts 37 which are connected by pins to sliding blocks 39, located in transverse grooves 40 in the tool-holders.
