Title: Improvements in the cooling of diesel oil engine cylinder covers
IPC: F01P1/02
Filed: 1926-11-30
Abstract: 279,657. Traill, R. Nov. 30, 1926. Cylinders, cooling; two- and four-strokecycle engines. - Cylinder covers of Diesel engines are cooled by causing a current of air from the atmosphere to circulate through them in con. tact with the inner walls. In the twostroke cycle - engine cylinder shown in Fig. 1, air is drawn by a pump S through an annular space 3 surrounding the fuel valve socket 4 and delivered to the ordinary scavenging port 10; alternatively the pump may force the air through the annular space 3 which is then directly connected to the ports 10. Fig. 3 shows the application to a four-stroke-cycle engine, in which the port nf the inlet valve 15 is surmounted by an annular wall 17 and engine suction draws air through the space 18 and an aperture 20 in the wall 17. Alternatively, a pump may either such or force, air through the head and deliver it to the passage formed by the wall 17, the apertures 20 being omitted. The covers may have internal vanes or ribs to increase the radiating surface and to guide the air.

Title: Tile and method of making the same
IPC: C04B33/13
Filed: 1930-10-09
Abstract: Tile bodies are formed by mixing finely-divided glass and magnesia-containing material so that the mixture contains more than 25 per cent of glass, moistening the mixture, moulding bodies therefrom, drying the moulded bodies and then burning them at a temperature and for a time sufficient to produce incipient or partial fusion of the glass.  As magnesia-containing material talc, calcined magnesite, dehydrated or calcined magnesium silicate, calcined serpentine, or steatite may be used.  Soda-, lead-, borosilicate-, or boraxglass may be used.  China-clay, silica, or a flux such as litharge may be added to the mixture. In an example 58 per cent of talc, 30 per cent of glass, 6 per cent of china-clay, 4 per cent of silica, and 2 per cent of litharge were used.

Title: Copolymers of vinylidene monomers and unsaturated anhydrides,or esters thereof
IPC: C08F22/04
Filed: 1962-08-08
Abstract: A copolymer of a maleic or substituted maleic anhydride or ester and a monoethylenically unsaturated vinylidene monomer having a strong tendency to heteropolymerize therewith contains at least 2.0 mols of the vinylidene monomer/mol. of the anhydride or ester and has a solution viscosity in 10% solution in acetone at 30 DEG  C. of up to 2.0 cs.  The substituted maleic anhydride may be methyl-, phenyl-, dimethyl- or chloro-maleic anhydride and the vinylidene monomer may be styrene, vinyl toluene, a vinyl alkylated or halogenated styrene, a vinyl alkyl ether, vinyl acetate, acrylate or methacrylate esters, ethylene or propylene. The copolymer may be terminated with the residue of a solvent, e.g. an isopropyl benzene or a ketone.  The copolymer or the anhydride monomer may be esterified with a monohydroxy organic compound, e.g. aliphatic alcohol, or the copolymer may be polymerized in the presence of the esterifying alcohol, the esterification being to an extent of at least 10% of half esterification.  The copolymer may be cross-linked with a polyhydric alcohol, e.g. 1,4-butanediol, e.g. in an organic or aqueous alkaline medium.  The copolymer may be formed in the presence of a catalyst, e.g. free-radical, by incrementally supplying the vinylidene and maleic monomer (in a mol ratio of 1.2:1), to an organic solvent system at at least 120 DEG  C., at such a rate that the stoichiometric excess of monomer is consumed in the copolymerization.  The catalyst may be a peroxide, e.g. benzoyl or dicumyl, a hydroperoxide or azo compound.  The solvent may be cymene or cumene and may be oxidized to form the catalyst in situ.  The copolymers may be used as plasticizers for resins, or may contain as plasticizers up to 5% of styrene oxide, epichlorohydrin or glicydyl ether.  The copolymers may be treated with methylol, e.g. formaldehyde, compounds or amines, and may be dissolved in organic solvents.  Specification 980,112 is referred to.

Title: Improvements in and relating to furnaces and method of operating the same
IPC: F27D11/02
Filed: 1924-12-19
Abstract: 226,559. British Thomson-Houston Co., Ltd., (Assignees of Steenstrup, C.). Dec. 20, 1923, [Convention date]. Soldering and brazing.-The temperature of a selected portion of a charge consisting of a number of parts which .are being soldered or brazed together in a furnace comprising a closed container supplied with a selected gas is controlled by means acting independently of the heating means. The control is effected by retarding the heating effect or increasing the cooling effect where desired by means of a localized stream of the selected gas. In a furnace of the type described in Specification 207,823, [Class 39 (iii), Heating by electricity], and heated by resistances 11<a>, Fig. 1, the charge rests on a sand bed 17<a>, and comprises a bucket wheel 18 to which the blades 23 and rim 21 are to be secured, Fig. 6. The rim is surrounded by an annular ring 19 embedded in the sand and connected at 25 to the supply of selected gas. During the heating and subsequent cooling of the charge the supply of gas to the ring 19, which is provided with a series of perforations 20, is regulated so as to maintain a uniform temperature over the whole of the wheel. A ring 10<a> is arranged as shown to direct the gas escaping from the ring 19 on to the rim 21. In Fig. 4, a steel pin 31 which is to be fused into a block of steel 30, is surrounded by a perforated member 19 connected to the supply of selected gas. In Fig. 5, two blocks 32, 33, which are to be fused together, are held in contact by plates 35 and bolts 36. The arrangement is placed in the sand bath in the furnace together with the fusing metal which may be copper and which is distributed over the joint, after which the temperature is raised to 1100‹ C. The selected gas is then supplied to the perforated pipes 19 arranged so as to direct the gas on to the bolts 36 with consequent cooling and contraction of bolts which exert a heavy pressure on the joint. The fusing metal may consist of a copper wire wound around the joint. The main supply of gas to the furnace through the pipe 15 may be reduced when gas is being supplied to the member 19.

Title: Powder feed welding torch
IPC: B23K9/29
Filed: 1963-08-02
Abstract: 970,288. Welding by fusion. E. A. HAWK. Aug. 2, 1963 [Aug. 3, 1962], No. 30679/63. Heading B3R. In a flame welding torch, the burner nozzle 20 has an axial passage 19 through which powdered welding material is fed and one or more passages 22 radially spaced from the axial passage 19 and through which gas is fed to form the flame, and a needle 35 in the axial passage has one or more valve elements 33, 36 normally closing the axial passage 19 and openable by manual actuation of the needle 35. The valve elements 33, 36 are actuated by a spring-loaded lever 62. The valve element 33 is formed on a rubber sleeve 40 fixed at its ends to the casing 28 and the needle 35. The welding powder, e.g. a metal, e.g. nickel-boron, and/or a ceramic, is supplied by gravity to the axial passage 19 from a container 45 having a screen 51 and a baffle 53. Oxygen and acetylene pre-mixed or mixed in the torch handle 10 are fed through a pipe 14 to the passages 22. The burner nozzle 20 has a rounded tip and cooling members 21 which may be longitudinal or annular fins or peglike projections. The needle 35 has a roughened exterior 66 and a projecting filament 35A which serve to agitate the welding powder. A bore through the needle 35 communicates with an enclosed chamber 44 having a diaphragm 44B connected to the needle so that actuation of the lever 62 causes a puff of air to pass through the needle to clear the end of the passage 19. In a modification flux in the form of a gas, liquid or powder is fed through the bore of the needle 35. A heat reflector 60, Fig. 6, may be clipped on to the burner nozzle. Alternatively the reflector 60 may be replaced by a tube of carbonaceous material which reduces the oxygen content in the surrounding atmosphere.
