Abstract: 1520896 Laying tiled floors THOMAS MARSHALL & CO (LOXLEY) Ltd 3 Aug 1976 [22 Aug 1975] 34990/75 Heading E1S [Also in Division F4] A method of laying a level tiled floor comprises laying a plurality of reference elements (shown shaded) to the required accuracy, arid suspending a plurality of blocks or tiles from a hanger member 28 between said reference elements until a bed of cement mortar or other bedding material has set sufficiently for the blocks or tiles to be detached from the hanger. The tiles are secured to the hanger by expansion bolts, nuts and bolts or adhesive. The reference elements may be tiles which may be incorporated in the floor, or part tiles which will be knocked away as tiling progresses, or beams with levelling jacks, or any combination of the three.

Title: Improvements in heating container for the rapid preparation of hot drinks
IPC: A47J36/28
Filed: 1947-12-31
Abstract: 637,611. Portable beverage infusers; drinking tubes. GOURGUES, A. Dec. 31, 1947, No. 35371. Convention date, Sept. 14, 1946. [Classes 14(ii), 28(i) and 129] A portable container for making or heating beverages is provided with a drinking tube 9 which is released by the melting of a piece 14 whereby the tube 9 is pushed outwards by a spring 10 until restrained in projected position by a flange 11 at its end. The container carries a removable reservoir 32 which is needle-punctured, its liquid then being poured into a central tube 18, and runs through its perforations to react with a substance 22 in a surrounding tube 16. The exothermic reaction heats up the water, &c., 21, which at a certain temperature melts the fusible seal 29 of an essence (tea) container 25 whereby the hot water mixing with it makes the beverage. At a higher temperature the fusible piece 14 melts as above to allow projection of the drinking tube 9. In the device in Fig. 6 the tubular, cartridge 16 carrying at its faucet top the oxidizing liquid holder 32 and puncturing needle 37 can be levered up, e.g., by a coin, and lifted out carrying with it the essence container 25 attached thereto. The bottom 28 of this container, which was secured by fusible metal allowing it to be pushed open by a spring 46, is also lifted out by its attachment to the spring 46. A fresh cartridge 16 with all attachments is then inserted and held by spring claws 24. The container is refilled with water through a plug hole. The drinking tube 9 is pushed back inside and held by a fresh fusible plug 14, Fig. 4. Another form of the device for cyclists, &c., comprises a quick puncturing of the oxidizing liquid chamber, comprising a screw down bar 55 with top spike 56 to perforate the chamber 32. The chamber is also pressed down against bottom spikes 59 to allow the liquid to run down into a number of perforated tubes 18 to distribute the liquid into the reacting substance. In another form (Fig. 10, not shown) steam normally escaping directly at the top is made to travel down a helical tube in the water chamber and so give up its heat before finally being allowed to escape through a spout at the top.

Title: Improvements in or relating to processes for the manufacture of magnesium or alloys thereof
IPC: C22B26/22
Filed: 1935-12-23
Abstract: A process for reducing magnesium from its compounds, including oxides, ores, sulphates, and chlorides, comprises mixing the powdered compound and powdered calcium carbide with a viscous carbonaceous binder such as tar or other hydrocarbon product, and heating the mixture in a reducing or inert atmosphere and in the absence of moisture, nitrogen, and oxygen, and in some cases under reduced pressure, to distil off the magnesium.  The resulting slag may be removed in dry form, or a liquid slag may be obtained by the addition of fluxes such as magnesium or aluminium fluoride. The magnesium vapours may be condensed to metal, or alloys may be obtained directly by condensing the vapour in contact with other molten metal.

Title: Method and apparatus for preserving foodstuffs
IPC: A23B5/10
Filed: 1931-12-28
Abstract: 391,256. Preserving food. NIERINCK, F., Chelmer Park House, Riverside, Chelmsford. Dec. 28, 1931, No. 35796. Convention date, March 19. [Class 49.] Eggs and other foodstuffs including meat, fish, fruit and vegetables are preserved by treating in an autoclave 10 first with vacuum and then with inert gas, e.g. carbon dioxide and nitrogen, under pressure and finally removing to storage chambers 1 where they are kept in an atmosphere of inert gas at about atmospheric pressure. In one form, boxes 9 or trays of eggs are run on a trolley 8 into the autoclave 10 which is closed and is then evacuated by a pump 11 which draws the oxygen from the spaces and the liquid within the eggs. Inert gas under pressure is then introduced through a pipe 14 and valve 15a from a reservoir 13 supplied from cylinders 12. A barostatic valve 29 admits gas to the autoclave if the pressure therein falls. After a short time, the eggs are removed to one of a series of concrete or other storage tanks 1 made impermeable to gas by coating with a layer of petroleum jelly, plastic paraffin wax &c. which may be protected by fitting slatted reinforcements over the walls and floor. The air is next withdrawn from the filled tank 1 by the pump 11 through valve 17 and pipe 15 and is discharged to the atmosphere through valves 19, 18, inert gas being simultaneously drawn into the tank through pipe 14 and valve 16. When the inert gas content of the exhausted gas is sufficiently high, the valves 18, 19 are closed and the valves 21, 20, 26a are opened and the gas mixture is returned to the tank 1 through a vessel 22 which contains an oxygenabsorbing material, the circulation being continued until the gas in the tank is free of oxygen. At intervals during the storage, the gas in the tank is circulated by the pump 11 through a cooler 24, by closing valve 26a and opening valves 25, 26, to keep the temperature in the tank at the desired level. Towards the end of the storage, the gas is circulated through a heater 27 until the eggs are raised to the temperature of the outside air. A spring- loaded or aneroid-operated valve 28 connected between reservoir 13 and pipe 14 maintains the gas pressure automatically in the tanks 1 and an aneroid-operated valve 29a allows gas to escape from the pipe 14 when the gas pressure in the tanks 1 rises more than a little above atmospheric pressure. In a further form (Fig. 2, not shown), an atmosphere of carbon dioxide &c. is maintained in the storage tanks 1, and the elimination of undesired gases from the chamber is effected by liquefying the carbon dioxide and then returning it free from oxygen to the tanks.

A lift cage 7 is supported by an endless chain 6, extending around idler sprockets 3, 5, a sprocket 1 on the shaft of a motor 9 and a sprocket 2, which is mounted on the cage 7 and is normally locked against rotation. When desired, for example when the cage stops between floors, the sprocket 2 can be unlocked by a control 8 to allow the cage to descend under gravity, the rate of such descent being limited automatically. A centrifugal-clutch type brake or a sliding vane or gear pump, whereby oil under pressure can be directed to rams arranged to force the cage guide shoes 10 against guide bars 11 in the lift shaft, may be provided. The cage release control may be actuated automatically if the power fails while the cage is in normal motion. In a modification (not shown), the chain and sprockets 1, 2 are replaced by a rope and capstan drums. In a further modification the chain or rope, instead of being endless, is secured at one end to the cage and at the other end to a winch drum, the drum being connected to the motor through a releasable coupling. In a further modification, the chain or rope is connected at one end to the motor-driven winch drum and at the other end to a drum mounted on the lift cage for rotation but which is locked in normal use.
