Title: Improvements in or relating to a process for the preservation of wood
IPC: B27K3/08
Filed: 1960-05-31
Abstract: A wood preserving composition comprises a solution of a preservative in a liquid aliphatic hydrocarbon medium, which boils below the boiling point of water and is gaseous at the impregnating temperature and atmospheric pressure but liquefiable under elevated pressure, and a co-solvent which dissolves the preservative and with which the liquefied hydrocarbon is miscible. The preservative protects the wood against attack from fungus or termites and may be pentachlorophenol, betanaphthol, tetrachlorophenol, ortho-chlorophenol, chlorinated beta-naphthol or copper naphthenate.  The hydrocarbon medium may be a liquefied petroleum gas, propane, butane or pentane or mixtures thereof. Suitable co-solvents are methyl alcohol, toluene, benzene, acetone and polyhydric alcohols.  Other materials may be added such as water repellants, e.g. paraffins, silicones or linseed oil, or dyes.  The wood is first subjected to reduced pressure then immersed in the solution, if desired after first pressuring the wood with an inert gas according to whether a full cell or empty cell process is preferred.  The solution is heated to produce the necessary pressure to impregnate the wood then the solution is drained off, vapours pumped off and the pressure reduced.  Due to residual heat in the wood all the hydrocarbon vaporizes and is removed leaving the preservative.  The impregnating conditions may be up to 200 DEG F. and 200 p.s.i.g.

Filed: 1955-07-04
Abstract: 787,040. Pistons. CHICAGO RAILWAY EQUIPMENT CO. July 4, 1955, No. 19311/55. Class 122 (1). [Also in Group XXII] A trunk piston for internal combustion, particularly Diesel, engines, is made of metal of relatively high thermal conductivity, such as aluminium, and has in its head 1 an-insert 3, 4 of relatively low thermal conductivity metal, preferably ferrous metal such as cast iron, that extends from the top face to the underside of the head and is in permanent surface contact with the remainder of the head. The insert may be formed with radial arms 5 integral with an annulus 6 adapted to carry piston rings 7. At least part of the interface between the metals is corrugated and the aluminium is cast around the ferrous metal in a manner such that a molecular bond exists between the metals. This bond may be achieved by immersing the insert in molten aluminium or aluminium base alloy until a thin layer of an alloy of the two metals is formed on the insert which alloy readily unites with the aluminium of the head when it is subsequently cast around the insert. Reference has been directed by the Comptroller to Specification 741,173.

Patent GB-427088-A (GB)
Title: Improvements in electric starting systems for internal combustion engines
IPC: F02N11/08
Filed: 1933-07-10
Abstract: 427,088. Starting prime movers. ECLIPSE MACHINE CO., Elmira, New York, U.S.A. July 10, 1933, No. 19487. Convention date, July 11, 1932. [Class 38 (iv)] In an automatic electric starting system for internal - combustion engines in which the control circuit 12 of an electromagnetic starting circuit switch 4 is controlled by a switch 13, 14 operated in response to cranking current and the voltage of an engine driven generator G, rotation of the engine in either sense causes connection of the starter battery 1 to the coil 26 of the switch 13, 14 which coil is also connected to the generator G. A switch 32 responsive to the pressure in the engine intake manifold operates between contacts 34, 35 so as to connect the battery across the coil 26 when the engine is rotating forwardly and also during backward rotation or backfire. A resistance 39 in the generator lead is provided for preventing discharge of the battery through the generator. The arrangement is such that, after starting, if the engine is rotating so slowly that the generator G is not operative, the starter switch is not operated because of the supplementary action of the battery 1 on the coil 26. During backfire, the switch gear is prevented from operating by the battery 1 until after the engine comes to rest. In a modification the control circuit of the switch 4 includes two sets of contacts in parallel, one set normally open, being controlled by the cranking current of the starter motor and the other set, normally closed, by two coils one of which is connected across the generator and the other across the battery when the starting switch is closed. The action of the generator energized coil is supplemented by the battery through a switch responsive to forward and backward rotation of the engine as shown in the Figure. One of the contacts controlled by cranking current is mounted on a bimetallic strip connected to a contact of the main starter switch so that prolonged cranking causes opening of the control circuit for the electromagnetic starting switch and stops cranking until the bimetallic strip has cooled. The action is then repeated. The fluid pressure responsive device operating the switch 32 may be of the diaphragm or of the pistonoperated type.

Abstract: 1,177,186. Digital transmission systems. SIEMENS A.G. 26 April, 1968 [28 April. 1967], No. 19813/68. Heading H4P. In a data communication exchange system, signals lasting more than a certain time, e.g. clearing signals, are detected. Each incoming line is associated with a respective detector, the detectors being sampled sequentially by clock pulses. In a first embodiment of a detector the time of occurrence and the direction of a change in level of a received signal are stored, and the time stored is subtracted from the time of occurrence of the next clock pulse fed to the detector. The result indicates the duration of the signal. The clock pulses recur at 120 m.sec. intervals. If no change in level occurs in the next 120 m.sec., the time stored is subtracted from the time of the next clock pulse. When there has been no change in level for at least 210 m.sec. the line is cleared. In a second embodiment, each clock pulse causes a store to be read out and then a counter, which feeds the store, to be incremented. The contents of the counter and store are erased when a change in level occurs on the associated line. When the number read from the store reaches a given number, the line is cleared.

Abstract: 1,168,905. Knitting-machines. K. I. J. ROSEN. 1 May, 1967 [22 March, 1967], No. 20142/67. Heading D1C. A device for feeding and storing yarn fed from a bobbin 2 to the needles of a knitting machine so as to maintain the supply of yarn at an even rate comprises a cylindrical body 10 constituted by being the rotor of an electric motor and which is periodically driven by energization of the stator 16 to cause it to rotate and wind yarn from the bobbin about its cylindrical surface. The upper end of the body 10 is slotted and houses a disc 14 having arms 15 which project through the slots of and out beyond the body 10, the disc being mounted on a pivot 19 and deflected downwardly by a micro-switch 18 in the circuit of the motor so as to engage the yarn as it is wound about the body. The yarn also engages a ring 20 mounted on a rail 19<SP>1</SP> on the bottom of the body to guide the yarn as it is withdrawn from the body and fed to the needles of the machine. When the body is rotated the yarn gradually builds up until it causes the disc 14 to tilt against the micro-switch causing it to break the supply to the motor and the rotation of the body to stop. Continued feeding of the yarn causes the number of turns on the body to become depleted until the micro-switch pushes the disc downwardly tilting it and simultaneously pushing the remaining turns of yarn about the body downwardly along its surface until the switch is again closed and the body again caused to rotate and replenish its supply of yarn about its surface. A tensioner 6 and a stop motion 7 are provided to engage the yarn on its path to the device.
