Patent GB-457490-A (GB)
Abstract: 457,490. Thermally - actuated gas valves. CHAPMAN, F. W., and OMNIA MANUFACTURING CO., Ltd., 48, Grosvenor Gardens, Westminster. May 30, 1935, No. 15786. [Class 135] A gas burner more particularly for water heaters, comprises a main valve 35 controlling the flow of gas to the burner jets 13, which may be controlled by the water pressure on a bellows 22 of the kind described in Specification 457,489, and an auxiliary valve 45 controlling both the main supply of gas to the valve 35 and the supply to a pilot jet 37. The valve 45 is loaded to close by a spring 9 but is held open on actuation by a lever 57 with arms 55 and 58 by a thermostatic catch 68 subjected to the heat of the pilot jet 37. A rod 65 is coupled to the arm 58 and is moved to the right on actuation of the lever 57 to open the valve and is retained in that position by the catch 68 carried by a thermal element 61. On the pilot flame being extinguished the rod 65 is released and the valve 45 is closed by the spring 9. A plug cock 51 may also be provided for positively shutting off the supply of gas.

Title: Preparation of ªŠ-caprolactam
IPC: C07D201/08
Filed: 1965-11-01
Abstract: e -Caprolactam is prepared by reacting e -caprolactone (or polymeric caprolactone) with ammonia at a temperature not lower than 200 DEG C. and at an elevated pressure, in the presence of an inert organic solvent.  The preferred temperature range is from 200 DEG  to 475 DEG C. Suitable solvents are pyridine, ethers, e.g.dibutyl ether, diamyl ether and dioxane, and hydrocarbons, e.g. toluene, xylene, decahydronaphthalene, heptane and octane, the preferred one being dioxane.  When the reaction is carried out as a continuous process, caprolactam can be separated from the other products, both intermediates and polymeric products, can be recycled to the reaction zone, the polymeric products undergoing depolymerization during recycling.  Very high yields may be obtained by adding to the recycled products an amount of caprolactone equivalent to the caprolactam distilled off. e -Hydroxy caproic acid amide and e -hydroxycapronitrile are formed as intermediate products.

Title: Method for removal of potassium nitrate from tobacco extracts
IPC: A24B15/24
Filed: 1977-11-11
Abstract: Potassium nitrate is removed from tobacco and recovered in relatively pure form. The process steps are as follows: The particles of tobacco plant are treated with water to produce an aqueous extract and a fibrous tobacco residue. The extract is concentrated and cooled. The potassium nitrate crystals formed are separated out from the extract. The tobacco residue, moulded into leaf shape, is recombined with the denitrated extract. As a result of the denitrification, the content of nitrogen oxides during combustion of the tobacco product is reduced.

Abstract: 1453935 Casting composite articles RICHARDSON CO 16 Oct 1973 [27 Oct 1972] 48111/73 Heading B3F [Also in Division H1] A battery container is provided with a terminal extending within and through a side wall 12 thereof, the said terminal being formed in situ by casting under pressure. The wall 12 may be made of polypropylene and has an opening surrounded by a boss 31 provided with circular projection 35 and radially extending lugs (27). To form the terminal, two die blocks 41 and 43 are clamped in position by rods 50 and 50A and molten metal, e.g. lead or a lead alloy containing antimony, injected into the mould cavity 45 via a passage 46 and gate 47. Some melting of the polypropylene occurs and this, together with the interlocking between the cast metal and the projections 35 and lugs (27), results in the formation of a fluid-tight seal between the terminal and the wall 12. The lower die 43 is provided with a shaft 51 having a threaded portion 53 which supports a steel nut 22 within the cavity 45. After solidification of the cast metal, the shaft is unscrewed from the nut 22 to leave the latter firmly embedded in the casting. The upper die block 41 is provided with a cavity 60 into which air and excess metal from the cavity 45 flows via a passage 48. When the cavity 60 is full, the back pressure created is detected and used to terminate the metal injection cycle. By adjusting the volume of the cavity 60 and the temperature of the molten metal, the heat input to the die cavity 45 can be controlled. The temperature of the die can be controlled by a coolant flowing through channels 61 within the die and by heating the die by means of induction rods (not shown). The metal is preferably cast at a temperature between 620 and 750 F. and under an injection pressure of from 850 to 1050 psi.
