Title: Improvements relating to the production of bactericidal bodies for the sterilization of water and other liquids
IPC: A61L2/238
Filed: 1934-01-18
Abstract: Bactericidal bodies containing oligodynamically active materials for the sterilization of water and other liquids are made in three different ways: (1) the materials, e.g. sand and kaolin, usually employed for making filtering bodies are mixed with a colloidal sol of an oligodynamically active metal or a sol of an oligodynamically active compound of such a metal and the mixture is formed into rigid porous filtering bodies of the desired shape; (2) existing rigid porous filtering bodies are impregnated with a sol of oligodynamically active colloids and a coagulation of the colloidal material impregnating the mass is produced by a later addition of an electrolyte, and (3) existing rigid porous filtering bodies are introduced as a diaphragm into an electrolytic cell in which the anions of the cathodic compartment and the cations of the anodic compartment precipitate in the interior of the said bodies an oligodynamically active gel; e.g. a solution of a soluble salt of an oligodynamic metal may be put into the anodic compartment and a salt of an alkali metal introduced into the cathodic compartment.

Title: Improvements in or relating to tool controlling device for glass cutting machines
IPC: C03B33/10
Filed: 1946-01-22
Abstract: 606,479. Cutting glass. UNION DES VERRERIES MECANIQUES BELGES SOC. ANON. Jan. 22, 1946, No. 2154. Convention date, Feb. 28, 1945. [Class 56] The downward movement of a glass cutter 1 into contact with a glass sheet A is controlled by a cam 16 rotatable about the point of support 15 of the cutter on a lever 2 and contacting the glass surface. When no glass is beneath the appliance a roller 14 swings a contact lever 11 to complete a circuit to an electromagnet 7 which through an arm 6 holds up the lever 2 and cutter. As the leading edge of the travelling glass contacts the roller 14, the circuit is opened and the cutter is free to drop except for the restraint of the cam. Further movement of the glass rotates the cam by friction and allows the cutter to descend gradually. As the trailing edge of the glass passes beneath the roller 14 the circuit is remade and the cutter raised; the cam is restored by gravity assisted by a spring 17. The cam may be mounted in a slot in an arm integral with the armature 9 and arm 6. The cam, instead of contacting the glass, may make contact with a member driven in synchronism with the glass. Alternatively, the glass may be stationary- and the appliance moved.

Title: Starting systems for i c engines
IPC: F02B3/06
Filed: 1976-01-21
Abstract: 1475975 Starting I.C. engines CATERPILLAR TRACTOR CO 21 Jan 1976 [8 May 1975] 02301/76 Heading H2H A starting system for an I.C. engine comprises means whereby the starter motor is energized for a predetermined time after a manually operable starting switch has been operated by a timing device but is maintained energized thereafter should the starting switch still be actuated. Movement of a starting switch 15 contact 16 causes heating of the glow plugs of a diesel engine, subsequent movement of the switch to contact 17 initiating the starting process by causing energization of the solenoid 13 of the starter motor relay. When the switch 15 is in the starting position an input signal from a battery 10 is applied to an EX OR circuit 24, the output signal from which is applied to a monostable flip-flop timer 26 to initiate operation thereof. The Q output of the timer forms one input to a NOR circuit 28 the other input of which is the output signal from the circuit 24 inverted by a NOR circuit 27. With these inputs the output of circuit 28, applied to a bistable flip-flop circuit 30, is such that the output of the circuit 30 is such as to cause turn-on of transistors 41, 44, 48 to energize the solenoid 13 to cause the starter motor to operate. When the timer 26 times out and if the start switch 15 remains closed the flip-flop 30 will remain set and the solenoid 13 energized. If when the timer times out the switch 15 is open the flip-flop 30 resets and the solenoid 13 becomes de-energized. When a switch 12 is closed prior to the operation of the starting switch 15 the flip-flop timer 30 is reset by way of an EX OR circuit 52. Should the circuit conditions be unsuitable for starting when the starting switch 15 is operated a transistor 66 is turned on by way of a transistor 62 and logic circuits 50, 56, 57 so as to cause a fuse 32 to rupture and protect the system.

Abstract: 691,249. Generating combustion products under pressure. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AERONAUTIQUES. Jan. 30, 1950 [Feb. 3, 1949], No. 2384/50. Class 51(i) [Also in Group XXVI] A continuous stream of air flowing in the main circuit of an internal combustion engine such as an athodyd or gas turbine engine is heated by the admixture thereto of hot combustion gases coming from an auxiliary circuit in which fuel is injected into a mixture of a comburent and combustion gases, the combustion of the fuel starting where the direction of the flow of the mixture is opposed to that of the main circuit and being completed before the outlet of the auxiliary circuit into the main circuit. The combustion gases can be taken from the main circuit or formed by burning,auxiliary fuel in the auxiliary circuit. In the arrangement shown, Fig. 2, the air flowing through the main circuit A-C-B is heated by combustion gases from the auxiliary circuit 2. The circuit 2 comprises a body 2a connected at the downstream end with chamber 1 through a deflector 4 and at the upstream end with the zone C through a deflector 5. The outlet of the deflector 5 is shaped as shown in Fig. 3 to provide passages x for the flow of combustion gases and passages y for the flow of the main air stream. Fuel is injected into the circuit 2 by a nozzle 3 surrounded by a conduit 2b which is so arranged that the fuel is only mixed with the hot gases in the conduit, the actual combustion taking place in the zone 2a. Cooling air jackets 6 are also provided. In another embodiment, Fig. 6, a part of the air from the main circuit passes through ducts 10, 11 to an auxiliary combustion chamber 8 where fuel from an auxiliary injector 14 is burnt. The combustion gases are mixed with air supplied through orifices 15 and the resulting mixture is used to support combustion of the fuel supplied by the injector 3. The hot gases pass through outlets 9 into the main circuit. A number of these combustion chambers may be arranged around an annular cowling through which the main circuit air flows. The central space of the cowling can be used to accommodate the shaft of a turbine driving a compressor feeding air to the combustion chambers.

Title: New halogen-containing trisubstituted phosphines
Inventor: HOFMANN EUGEN
IPC: C07F9/50
Filed: 1960-01-26
Abstract: Compounds of the general formula PZ3 in which at least one of the constituents Z have the structure -CHnX3-n, X being a halogen atom, e.g. chlorine, and n being 0, 1, or 2 and any of the constituents Z which do not have the said structure are hydrocarbon or fluorinated hydrocarbon groups, are obtained by reacting, in the substantial absence of oxygen, compounds of formulae R1R2PH and CHnX4-n in which R1 and R2 are hydrogen atoms, hydrocarbon groups or fluorinated hydrocarbon groups, X is a halogen atom and n is 0, 1 or 2.  The reaction may be carried out in an inert solvent, e.g. a hydrocarbon such as benzene, toluene or petroleum ether, but it is preferred to carry out the process by using an excess of the reactant CHnX4-n, e.g. CCl4, in which the other reactant R1R2PH is soluble.  The process is preferably effected at elevated temperature, e.g. by refluxing the reactant mixture in an inert atmosphere.  R1 and R2 may conveniently be aromatic hydrocarbon groups, e.g. phenyl or monoalkyl phenyl in which the alkyl group contains up to 3 carbon atoms, alkyl groups or benzyl. Specified fluorinated hydrocarbon groups are fluoromethyl and fluorophenyl.  The invention also comprises compounds of the formula PZ3 in which one or two of the constituents designated by Z have the structure -CHnX3-n as defined above and the constituent or constituents Z which do not have the said structure are hydrocarbon or fluorinated hydrocarbon groups.  An example is given for the production of (C6H5)2PCCl3\t by refluxing diphenyl phosphine with CCl4 under an atmosphere of argon.  The product decomposes on distillation to form (C6H5)2PCl.  The products of the invention may be oxidised by means of molecular oxygen to form compounds of the formula O=PZ3 wherein Z is as defined above.  Thus (C6H5)2PCCl3 may be oxidised in air to for (C6H5)2P(O)CCl3.
