Title: Improvements in or relating to an internal combustion engine piston
IPC: F02F3/00
Filed: 1968-07-12
Abstract: 1,206,356. Cooling pistons. MASCHINENFABRIK AUGSBURG - NURNBERG A.G. 12 July, 1968 [15 July, 1967], No. 33295/68. Heading F2T. [Also in Division F1] The wall of a combustion chamber 4 in the crown of a piston is cooled by a solid substance 6, e.g. sodium or Woods metal, which liquefies at about 180‹ to 250‹ C. Lubricant is also supplied to a second cooling space 11 in the piston crown. At starting the air space 5 above the solid coolant serves to insulate the wall 4 and help it heat up quickly; when the coolant has liquefied it is shaken about in the space 5 and serves to cool the whole wall. The space 5 may be formed between the wall 4 of the combustion chamber insert 2 and a wall of the piston or between the wall 4 and a sheet metal insert 14 clamped in space by the insert 2.

Abstract: 603,132. Cooling systems for engines. EATON MANUFACTURING CO. Dec. 10, 1945, No: 33332. Convention date, Aug. 22, 1944. [Class 64(iii)] [Also in Group XXVII] A cooling system for an engine 10, Fig. 1, with a radiator 11 consists of a fan 15 and coolant pump 14 both driven from a power shaft 16 through an electromagnetic clutch 20, Fig. 2, having an energisable rotor 24 and a magnetic material casing 22, slippage occurring between the members 22 and 24 when the fan has reached the maximum speed for efficient cooling. In the operating circuit, Fig. 2, a bulb 40 inserted in the cooling jacket operates the switch contacts 37, 38 by pressure generated in it when the engine reaches a certain temperature, expanding a bellows 39 and so starting the cooling fan and pump. In a modification, the bellows may operate the arm of an electric rheostat so increasing clutch current with increasing engine temperature. In a further modification, a three-pole switch is used, the first part of the travel of the bellows closing the clutch circuit with a series resistance and the second part of the travel short-circuiting the series resistance to give maximum current to the clutch. In a further modification, a cooling system which is usable with all the above circuits has its fan only driven through an electromagnetic clutch. A key switch 34, which may be the standard ignition switch, is included in all circuits.

Title: A process of manufacturing refractory articles of clay
Filed: 1927-12-12
Abstract: 291,305. Hochhut, J. Dec. 12, 1927. Processes.-Refractory clay articles, such as glass melting-pots, are formed by moistening with water a mixture of shortening-material and clay to produce a loose incoherent mass, introducing such mass successively in small portions into an open mould, and stamping the portions so introduced. The shortening-material is moistened with the whole of the water, with or without addition of a small quantity of fresh dry ground clay, before mixing with the clay. To facilitate removal of complicated shapes from the mould, a small addition of oil may be made. The articles are removed from the mould immediately after completion and dried and fired in the usual way. As an example, 40-45 litres of water are gradually mixed with 300 kg. of disintegrated burnt clay and 215 kg. of disintegrated crucible shivers; 425 kg. of air-dried ground clay are then gradually added with continuous agitation to produce the mass. The stamping is preferably effected by pneumatic stamps.

Title: Improved expanded polyamides and their production
IPC: C08J9/04
Filed: 1962-09-05
Abstract: The invention comprises a foamed 6-nylon composition having an apparent bulk density of less than 0.9 g./c.c. and matrix density greater than 1.140 g./c.c., preferably surrounded by an integrally bound skin or shell of unfoamed 6-nylon.  A polymerizable composition comprises a mixture of anhydrous e -caprolactam, e.g. 80% by wt., an anionic catalyst, a cocatalyst or synergistic co-catalyst mixture. The composition may contain (i) a gas producing agent, e.g. a compound which volatilizes or decomposes at 100-200 DEG  C. to give an inert gas; (ii) 0.1-5% of a surface-active agent such as a long-chain fatty acid alkali metal salt which may contain one or more C-C double bonds, e.g. K stearate, an alkali metal sarcosinate, e.g. Na N-laurylsarcosinate, or an alkali metal (e.g. Na) oleylmethyltaurate; (iii) an anionic catalyst which may be formed by heating, e.g. at 68-220 DEG  C., e -caprolactam with 0.01-10 mole per cent of an alkali or alkaline earth metal or a derivative thereof, e.g. Na methylate, or a hydride, amide, alkoxide, hydroxide, alkyl or by using a preformed metallic derivative of caprolactam. The foamed nylon composition is made by heating at 100-220 DEG  C., in the presence of an inert gas dispersed therein until a solid polymerized foam is obtained.  The heated composition may be vigorously agitated in the presence of an inert gas, e.g. by passing nitrogen through the mixture, or heated without agitation if a gas producing agent is used.  The composition may be transferred to a mould either before foaming or as a partially polymerized foam.  The composition may be externally heated to 130-170 DEG  C. to initiate polymerization. Anionically catalyzed caprolactam is mixed with the blowing agent, if used, and a co-catalyst at 70-200 DEG  C., and transferred to a mould or transferred to a mould and then the co-catalyst added. The co-catalyst may be an organic isocyanate such as an aromatic isocyanate, e.g. phenyl isocyanate, methylene-bis-(4-phenylisocyanate), an adduct of caprolactam and an organic isocyanate, an acyl derivative of caprolactam, e.g. acetyl caprolactam, or a substituted triazine, e.g. a triaryloxytriazine and particularly 2,4,6-triphenoxytriazine. Blowing agents may be benzene, toluene, cyclohexane, trioxane or 1-hexene, used in amounts 1-15% by weight or chemical agents such as a a 1-azobis-(isobutyronitrile) and and a a 1-azobis(cyclohexanecarbonitrile). Additives may be caprolactam soluble polymeric materials, e.g. 6-10 nylon, colouring agents, e.g. 1-methylamino anthraquinone, pigments such as carbon black, titanium dioxide, ultramarine blue, cadmium yellow, cadmium red, bronze sienna.  One example discloses the manufacture of a bowling pin, another a cup.

Title: Improvements in sliding gate valves for the control of fluids
IPC: F16K3/18
Filed: 1955-11-19
Abstract: 821,616. Flued-actuated valves. MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE SAINT-GOBAIN CHAUNY ET CIREY S.A. DES. Nov. 29,1955 [Nov. 29, 1954], No. 34185/55. Class 135. In a sliding gate valve for the control of fluids wherein the gate is moved between its open and closed positions by a piston and cylinder operable under the control of a pressure fluid, a passage places the cylinder into communication with a packing element associated with the gate so that the pressure of the fluid deforms the packing into sealing engagement with a seal on the valve body when the valve is closed. A gate member 27, Fig. 1, having lateral elements 27, 28 for engagement with guide posts 30, 31 is formed with a cylindrical bore 32 which cooperates with a fixed piston 37 having concentric tubes 34, 35 connected thereto. The bore 32 communicates with annular recesses 41, 42, Fig. 2, in the working faces of the gate member by way of passages 40, 43, the recesses being covered by resilient plastic diaphragms 44, 45 secured to the gate member. To open the valve, pressure fluid is admitted to the tube 34 whence it passes through a port 39 to the space above the piston, whilst pressure fluid from below the piston is exhausted through the tube 35. To close the valve pressure fluid is admitted to the bore 32 through the tube 35 and exhausted therefrom through the tube 34, at the same time pressure fluid passes to the recesses 41, 42 and when the valve is closed the diaphragms 44, 45 are distorted to sealingly engage seats 48, 49 in the valve body 36. In a modification, the gate member is connected to a piston to slide in a fixed cylinder.

Title: Improvements relating to aquatic probes
IPC: G01K1/02
Filed: 1965-08-10
Abstract: 1,120,635. Measuring fluid properties electrically. BUZZARDS CORPORATION. Aug.10, 1965 [Aug. 13, 1964], No.34205/65. Heading G1N. A device to be deployed from a submarine includes a probe section 27 with an information retrieving device 32, and an evacuated float section 14 held on to the probe section so that the device has positive buoyancy but releasable when the device reaches a predetermined depth, so that the probe sinks under its own weight and the float fills with water and also sinks. The probe has a combined thermistor and electrode 32 which projects into nozzle 35 of the float and the junction is sealed by an O-ring 36. The probe and float are stored in an evacuated canister 22 closed by a conductive seal member which can be melted by passing an electric current therethrough. After removing a protective cap 40 the canister is inserted in a launching tube on a submarine so that contacts 24, 26 engage mating contacts in the tube. The tube is then filled with sea water and before it is completely full the seal 38 is burnt off so that the vacuum in canister 22 is filled with water and probe 27 and float 14 are held in tight engagement by the water pressure. The float and probe then float out of the canister, wire from a fixed spool in the canister uncoiling as a result of horizontal displacement and wire from spool 16" uncoiling as a result of vertical displacement. At a predetermined depth the weight of probe 27 and the hydrodynamic drag acting on it exceed the pressure exerted by the water and the probe and float separate. Electrode 32 then contacts the sea water to complete a circuit from the submarine through cable 16, thermistor and electrode 32 and back to the submarine. The float meanwhile fills with water and to prevent it reaching the surface before doing so nozzle 35 is offset so that the float undergoes a tumbling movement. The depth at which separation occurs depends upon the diameter of O-ring 36.
