Filed: 1928-03-08
Abstract: 286,725. International Fireproof Products Corporation, (Assignees of Vivas, F. S.). March 11, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Fireproofing; proofing against bacteria etc.; proofing processes.-Wood and other material is fireproofed and preserved from decay by treatment successivelv with solutions of chlorides and boric acid and of metallic sulphates respectively, so as to precipitate, insoluble sulphates in the wood. Resinous wood may be first treated to remove the resin, for instance by means of sodium hydrate. In the.process described, the wood is first treated in a closed vessel with a solution containing 8 ounces of sodium hydrate to the gallon of water for about 1“ hours at 212‹ F. The solution is drawn off and a vacuum created in the vessel. A solution containing 2¢ lbs. of calcium chloride, ¢ lb. of ammonium chloride, and ¢ lb. of boric acid to each gallon of water is then run into the container, with admitting air. The solution is placed under a pressure of 150 lbs. per square inch, and the temperature maintained at 175‹ F., except in the case of white oak, when the solution is used cold. Pressure is maintained until the wood has absorbed a volume of solution corresponding to 220 lbs. of solids per thousand cubic feet of timber, the volume absorbed being read off by means of a gauge glass on the vessel. The solution is withdrawn from the retort and hot air blown in for an hour to dry the timber. A solution containing 4 ozs. of zinc sulphate and 4 ozs. of aluminium sulphate to the gallon of water is then run into the vessel and placed under a pressure of about 150 lbs. per square inch, maintained for one to two hours. The timber is then treated with hot air. for about 6 hours. If the timber is for use in or near water, aluminium sulphate in the second solution is replaced by copper sulphate. The treatment with sodium hydrate solution saponifies the resins of the wood, which collect at the bottom of the vessel and are drawn off as a by-product.

Title: Automatic weighing and delivering machine
IPC: G01G13/00
Filed: 1919-03-22
Abstract: 141,871. Brian, J. March 22, 1919. Automatic-feed weighers.-In an automaticfeed weigher, the feed-gate F is opened by the fall of a lever G which is freed by the displacement of a catch L, the lever G being raised again into engagement with the catch during the weighing operation, by the end K<3> of a weighted lever K which rests upon the weigh-beam P. The feedgate F is connected by a slotted link J to the weighted lever G, and as the weigh-beam P descends, the lever K raises the lever G and thus permits the feed-gate to descend to the dribble feed position, wherein the feed-gate is held by a finger M resting upon a catch N attached to a lever 0. In this position, the lever G has been raised into engagement with the catch L and is prevented from further upward movement by a stop L<2>. On completion of the weight, the weigh beam P displaces a catch Q, and the lever 0 falls, thus removing the catch N from the finger M and allowing the feed-gate to close, sufficient loose motion being provided in the slotted link J. The long arm of the lever 0 also strikes a. stop E away from a toggle B and allows the discharge gate A to open. The toggle B, by means of a pin B<3>, swings a lever S into engagement with a catch R and afterwards, during the closing of the discharge gate, knocks up the catch R so that the lever S falls against the catch L and liberates the lever G, which thereupon re-opens the feed-gate.

Title: Improvements in and relating to control systems for electrically driven reciprocating motions
IPC: H02P7/00
Filed: 1931-03-09
Abstract: 374,162. Control of motors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and GREEN, W. B., 47 Portland Road, Rugby. March 9, 1931, No. 7290. [Class 38 (iii).] Travelling between predetermined limits.-A motor driving a reciprocating machine, such as a push bench for the manufacture of seamless steel tubes, is controlled by a controller 1 moved to one of its "on" positions by an oil servomotor 3, and returned to its "off" position by the main motor as the latter reaches the end of its travel. The main motor acts on the controller through cams 16, 17, links 22, 23, 24 and a yieldable clutch interposed between the link 24 and a wheel 25 geared to the controller, so that the operation of the servomotor 3 to oppose the return of the controller under the action of the main motor is prevented. When one of two electromagnets 11 is energized from a remote point, the servomotor 3 is actuated to turn the controller 1, to one of its extreme positions, whereupon the circuit of the particular electromagnet energized is interrupted. As the controller 1 is turned, the main motor is accelerated and the lower link 22 is moved to the left.. The main motor in revolving actuates cams 16, 17 adjustably mounted on a cam wheel 13 so that towards the end of its travel, the cam 16 pushes the link 22 to the right, and returns the controller 1 to its "off" position. If the remote controlling means for the electromagnet 11 is still operated, the controller, in moving to its "off" position, again energizes the electromagnet 11, so that the main motor and the servomotor act in opposition on the controller 1. As the torque transmitted by the clutch 26 increases, however, the clutch yields, and the relative movement between its two members, opens contacts carried by them to interrupt the circuit of the electromagnet 11. Each cam adjustably carries a striker 18, 19 for tripping limit switches 20, 21 to obtain accurate positional stopping of the bench by establishing a "suicide" connection for the generator supplying the main motor. In a modification the oil servomotor 3 is replaced by two electric motors continuously running and connected through electromagnetic clutches with two pinion wheels engaging a wheel on the controller shaft, the controller being operated in a desired direction by energizing the appropriate clutch.

Abstract: 115,513. Western Dental Manufacturing Co., and Osborn, H. May 25, 19] 7. Teeth, artificial. - A two-part pattern for the production of a suction surface in a vulcanite denture comprises a relatively thick soft-metal pattern-block 30 and a thin soft-metal mould-plate 20 having contacting surfaces of the same contour. The pattern as a whole is bent to conform to the plaster matrix 42 and is secured thereto and, after packing and compression of the vulcanite material, the moulding-flask is opened, the pattern-block 30 removed and the space so produced is filled with rubber which will remain soft after vulcanizing. The mould-plate which remains in the flask, and which may be supported at its centre by a supplementary shield 34, gives the required form to the surface of the soft rubber. The pattern-block serves to protect the rugosities of the mould-plate during bending to the shape of the plaster matrix. The patterns may be of circular or other shapes such as those indicated in Figs. 1, 5 and 8, and may be employed for upper or lower dentures.
