Filed: 1925-01-26
Abstract: 228,194. Schneider, L. Jan. 25, 1924, [Convention date]. Wire.-A wire is made by mechanically enclosing an electric conductor in a covering of magnetic material coated on its inner surface with a film of the conducting metal or alloy. The covering, for example a tube of soft Iron is coated electrolytically or by the action of copper sulphate. The tube is filled with copper or other conductive metal by pouring the molten metal at 1090‹ C. very slowly into the inclined tube closed at one end and maintained at a temperature of 300‹ C., the tube being subsequently carefully raised to a vertical position and the temperature allowed to drop to between 500‹ C. and 800‹ C. The filled tube is drawn by a succession of heating and drawing operations at 800‹ C. In the finished cable the copper core has a thickness of about 4 mm. and the covering about 6 mm.

[Class 102 (i)] A device for regulating the fuel-injection pump of an internal-combustion engine, of the kind operating with a relief or overflow at the end of each delivery stroke, comprises a slide valve 19 displaceable in the suction passage 11 of the pump cylinders 14 for variably throttling said passage, displacements of said valve being produced against the action of a spring 31 in dependence upon the fuel pressure in the relief passages 12, 13 (i.e. by the pressure difference between the suction and relief passages), which pressure (or pressure difference) varies with the speed of the engine. The pump cylinders 14 are connected by ports 18 to passage 12 and by ports 17 to tapered annular grooves 29 and ports 30 in the hollow valve 19. The latter is provided at one end with a throttle opening 20, and its movements are limited by adjustable stops 21, 22, whilst the loading of the spring 31 is adjusted by screwing in and out a hollow plug 50. In a modification, the throttle passage 20 is located in the cylindrical wall of the valve 19 and is fitted with an externally-operated needle valve. Each piston 15 may be initially adjusted on a test bench, to compensate for inaccuracies in machining, and to determine the quantity of fuel normally delivered, by providing them with milled flats 37 to engage slotted toothed segments 38 which are held in the desired position by set screws 39. Opposite the ports 17, 18, the pump casing may be closed by plugs 40, 41. The Specification as open to inspection under Sect. 91 states also that the pump casing may be die-cast in grey iron or light metal, and the cylinders and passages formed by means of bushes made of steel or brass which are cast, pressed, or shrunk into position, preferably in the form of solid bodies which are afterwards bored. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to the manufacture of 2:3-dimercaptopropanol derivatives
Inventor: BRODRICK CHARLES ISAAC
Filed: 1950-01-31
Abstract: A water-soluble derivative of 2 : 3-dimercapto propanol is prepared by heating a mixture of approximately equimolecular proportions of 2 : 3-dimercapto propanol and succinic anhydride, and reacting the acidic product formed with a basic material to form a water-soluble salt, e.g. an alkali metal salt.  The initial reaction is preferably effected in an inert atmosphere; an inert organic solvent may be present.  The acidic product of the initial reaction may be purified, e.g. by dissolving the product in aqueous alkali carbonate, acidifying the solution, thereby precipitating the acid product and extracting the latter with, say, chloroform.  Formation of the salt is preferably effected in absence of water, e.g. by using an alcoholic solution of a sodium alkoxide to neutralize an alcoholic solution of the acidic product, the concentrations being such that the desired salt then precipitates out.  In an example, succinic anhydride and 2 : 3-dimercapto-propanol are heated together in an atmosphere of nitrogen on a steam bath and the acidic product converted into the sodium salt which is stated to have about 1/16 th of the toxicity of 2 : 3-dimercaptopropanol.  Specification 623,377 is referred to.

Title: Improvements in machines for wrapping and sealing metal foil
IPC: B65B19/22
Filed: 1924-02-01
Abstract: 233,048. Marks, E. C. R., (Conley Foil Co.). Feb. 1, 1924. Packeting by wrapping-up.-Relates to a machine for wrapping and sealing metal foil in the manufacture of packages of cigarettes &c. According to the invention, relatively thin metal foil, for instance of a thickness of less than <3>/1000 of an inch, is applied around partially formed cigarette packets by a machine comprising means for forming and folding upper and lower side flaps and means for forming upper and lower end flaps characterised by the fact that one of said end flaps is folded by a partial rotation of the package. Packages are fed from a magazine 2, Fig. 4, by a plunger 3 beneath a plate 18 which holds it until the plunger returns, whereupon the package drops to the position 56. Foil is fed from a roll 33 by rolls 34 35, past an evening roll 33 having pinions at the ends to engage racks 39, and between rolls 38, 46 into a guide in which a length is severed by knives 41, 42. At the moment of severance, the packet 56 is moved to the left by the next succeeding package advanced by the plunger 3, and carries the foil with it between plates 57, 60, Figs. 4 and 8, which apply the foil to the top and bottom of the package. The end 5 of the plunger 3 is covered with felt and is cut away at the corners 5'. A member 58, also covered with felt, folds the foil on to the narrow sides of the package, a roller 64 preventing wrinkling. Folding members 61, 69 complete the folding at the sides of the package, which is advanced on to a platform 72, Fig. 4, on a rocking arm 73, and is temporarily secured thereon by plates 75, Figs. 4 and 11. Fusing irons 86 are then moved in to secure the folds at the sides of the package. A portion 86<1> of the irons is cut out to prevent contact with a single thickness only of the foil. The plunger 3 is withdrawn and folders move inwardly while the irons are still in position to tuck in the narrow end folds of the packet. A finger 103, Figs. 4 and 14, moves upwardly to fold in the lower end flap and continues moving upwards until a stop 106 contacts with the underside of the table and turns the finger 103 into the position shown in Fig. 14, where it contacts with the underside of the top end flap and assists in defining the subsequent last end fold. The rocker arm 73 swings about a pivot 74, a folder 128 turning down the last end fold. After the carriage has turned into the position shown in Fig. 16, a stop 134 contacts with the carriage 132 on which it is mounted, whereupon the carriage moves bodily to the left to bring the right hand packet beneath a sealing iron 140, which descends and completes the sealing. The folder 128 is covered with felt and is resiliently mounted. The packages are moved along a guideway 149 by succeeding packages and are removed from the machine, and may be subsequently wrapped in paper. Specification 173,783 is referred to.
