Title: Improvements in or relating to the cooling liquid circuit of an internal combustion engine
IPC: F01P5/10
Filed: 1944-12-15
Abstract: 584,212. Cooling systems for engines. NAPIER & SON, Ltd., D., GREENLY, K. H., and MARCELL, R. C. Dec. 15, 1944, No. 25169. [Class 64 (iii)] [Also in Group XXVIII] A cooling liquid circuit for an engine designed to assist the operation of the circulating pump comprises an engine A, radiator H, pump C and a header tank B from which water flows by gravity and is drawn through a pipe F by a venturi injector E situated in a pipe D on the suction side of the pump, and supplied with water from the radiator. The venturi may be supplied with water from the delivery side of the pump, but in either case it draws water from the header and the water travels from the venturi to the suction side of the pump. The venturi may comprise a nozzle situated in the throat of the venturi; the water from the header entering the annulus round the nozzle, or it may comprise a constriction in the tube having a number of holes in the walls of the tube where its diameter is least, the whole being enclosed in a cylindrical sleeve into which water from the header flows.

Title: Improved method of and equipment for shot-blasting and the like
Inventor: HIBBS JOHN BRIAN
IPC: B24C5/08
Filed: 1965-06-15
Abstract: 1,084,496. Blasting. BRITISH STEEL CASTINGS RESEARCH ASSOCIATION. June 10, 1966 [June 15, 1965], No. 25186/65. Heading B3D. [Also in Division H2] A method of shot-blasting comprises introducing particles of ferromagnetic material, e.g cut wire shot, into an electromagnetically induced travelling magnetic field, the particles being given kinetic energy by being drawn into the field and then accelerated by acceleration of the field as a travelling wave in the required direction of travel, the energy in the wave being dissipated to allow the particles to be discharged with their acquired velocity to an article to be shot-blasted. A travelling wave gun 1 is directed towards a rotary table 2 for carrying workpieces. Spent blastant together with material removed from the workpieces passes through an openwork floor 4 to a hopper 5 and thence to an elevator 6. Waste is removed in a separator 7 and blastant goes to a hopper 8. A demagnetizing coil 9 removes residual magnetism. A magnetic gate 10 phases the passage of blastant from the hopper 8 to the gun 1. The gun 1 may be oscillated. For blasting small articles the table 2 may be replaced by tumbling equipment.
Patent GB-736600-A (GB)
Title: An improved process for the production of carbon monoxide and hydrogen from methane or the like
IPC: C01B3/38
Filed: 1952-10-08
Abstract: Carbon monoxide and hydrogen are produced by mixing a gas comprising or consisting of a hydrocarbon such as methane with oxygen (air), bringing the mixture into contact with a nickel- or cobalt-containing catalyst, preferably on a magnesite base, and bringing the products into contact at elevated temperature with a catalyst containing iron (but no nickel), the quantity of oxygen (air) used being such that a part of the hydrocarbon remains to be oxidized in the second stage, and the first stage being continued until substantially no free oxygen remains.  In normal operation the first stage catalyst amounts to about 20 per cent by volume of the total catalyst.  A space between the reaction zones is preferred, but the catalysts may be located in a single reaction chamber, e.g. a tubular or tower-like chamber in a heating oven. If a product free from, or poor in, nitrogen is required, pure oxygen or air of increased oxygen content is employed, steam then preferably being added to the initial reactants.  The catalyst for the first stage may be produced by impregnating burnt magnesite with nickel nitrate, heating the product and treating with hydrogen: the second catalyst may be prepared by burning iron filings mixed with activating ingredients such as clay or magnesium oxide, mixing the resultant melt, cooling, comminuting and reducing with technical hydrogen at 400-500 DEG  C.

Abstract: <FORM:1044043/C4-C5/1> A continuous process for rendering animal fats comprises the steps of cooking animal material in a confined steam atmosphere under pressure to cause the material to separate into meal, fat, and proteinaceous liquid, and obtaining separately the meal, the fat and the proteinaceous liquid.  The meal may be dried and in further preferred embodiments a portion of the proteinaceous liquid may be passed into the meal in the steam atmosphere to strip fat from the meal and another portion of the proteinaceous liquid may be passed into the separated meal to obtain protein enriched meal. The invention also comprises apparatus for carrying out the above process.  Animal material to be treated is passed through inlet 18 into the lower end of housing 16 which is provided with a helical screw element 24. Steam introduced via inlet ports 34 maintains the animal material at 300-350 DEG  F. and 50-120 p.s.i.g.  After cooking and rendering, meal is discharged into screw conveyer 36 and rotary drier 40.  Combined fat and liquid protein passes to decanter 52 and fat is taken off through line 68.  Stickwater, i.e. liquid protein, is recycled via line 73 to the hollow  shaft 26 and via spray nozzles 32 to the cooking zone. Stickwater is also passed to surge tank 77 and is then pumped on to meal via spray nozzle 83 to enrich recycle meal with protein and provide 35% by weight moisture on mixing with meal in conveyer trough 38.  The final product leaving drier 40 via outlet 49 preferably contains 8% by weight moisture and the moisture content of the fat product is reduced to 0.03% weight.
