Title: Improvements in or relating to the preservation of foodstuffs in refrigerator cabinets
IPC: F25D11/02
Filed: 1938-04-13
Abstract: 513,698. Refrigerators; carbon dioxide. ELECTROLUX, Ltd. April 13, 1938, No. 11401. Convention date, April 14, 1937. [Class 29] [Also in Group III] Domestic cabinets cooled by absorption refrigerating apparatus heated by gas or liquid fuel are supplied with dried, cooled and possibly filtered gaseous products of combustion of the fuel, to provide a preservative atmosphere containing carbon dioxide. The combustion products are led through a conduit 19 branched horizontally from the flue 18 of the generator 14 of the refrigerating apparatus to a gas drier and cleaner 20, whence they flow through a downwardly inclined pipe 21 provided with cooling fins 22 and an upwardly inclined conduit 23 in thermal contact with the evaporator 13 and pass into the storage space. The cabinet air is displaced through a controllable opening 36 in the lower part of the door. Moisture separated from the gases is drained through traps 24, 35 into the drip tray 25 of the cabinet. The gas drier and cleaner comprises an outer annular chamber packed with a layer 34 of coarse sand or gravel covered by a layer 33 of coarse cooking salt, magnesium or calcium chloride or like water absorbent, and an inner chamber 39 containing activated charcoal to deodorise the gases. With certain fuels the deodorant may be omitted. The surfaces of the cooling chamber. evaporator and ice trays may be protected against the carbon dioxide by coating with chromium or nickel plating, oxides or organic substances. A separate storage chamber or compartment may be provided for vegetables &c. requiring a normal atmosphere. The carbon dioxide in the combustion gases may be chemically combined with sodium-carbonate solution or other agent at a low temperature and released therefrom by heat or electrolysis as required. The Specification as open to inspection under Sect. 91 comprises also the following:- The carbon dioxide may be supplied to the storage space from a source independent of the refrigerating apparatus, as by evaporation by heat of solidified carbon dioxide stored in an insulated container in the storage compartment, or by evolution of the gas by chemical action on or electrolysis of a compound. Such evolution may be effected by electric energy supplying the cabinet lighting system or electrically driven refrigerating apparatus for the cabinet. This subject-matter does not appear in the Specification as accepted.

Abstract: 883,717. Reactors. BABCOCK & WILCOX Ltd. March 31, 1960 [April 3, 1959], No. 11438/59. Class 39(4) In a heterogeneous nuclear reactor, water flows upwards through the core and acts as both coolant and moderator. The core is formed of vertical fuel and control rods supported at their ends, within the cylindrical pressure vessel, by an upper and a lower lattice having a cellular structure. The sides of each cell incorporate a vertical tube through which flows the coolant from a fuel chamber. As shown, water flows into pressure vessel 1 through inlet 14 and part moves upwards through passages 18, 28 52 and by apertures 19, 26 into compartments 51 of the upper core support 37. From 51, water flows through apertures 47 in plate 45 through the fuel element chambers 31 into the lower chamber 67. Further coolant from 14 flows downwardly through passage 72 and enters 67 through orifices 73. From 67, part of the coolant flows upwards through orifices 74 over the outside of the control rods 32, into chamber 95 and the remainder passes upwardly through the inner fuel element chambers 31 through tubes 80 to 95. The coolant discharges from 95 to the outlets 13. Each control rod 32 has a lower follow up section 34 of low neutron capture cross section material and each fuel element chamber container 56 is substantially surrounded by the control rod ribs 33. Each control rod rests on a resilient stop 75. Specification 883,716 is referred to.

Abstract: 216,860. Sury, J. J. C. M. May 30, 1923, [Convention date]. Pigment processes; photo-mechanical printing- surfaces.-A pigment printing paper has incorporated in a colloidal coating, which may consist of gelatine, gum arabic, albumen, or a mixture thereof, a temporary colouring matter permeable to light and capable of being dissolved by a diluted acid with effervescence of gas, whereby the colloidal coating is rendered spongy. The colouring matter, blue in colour, is preferably composed of a silicate of aluminium and sodium and pentasulphide. of sodium, and is mixed with a powdered inert white substance such as barium sulphate or kaolin which aids in keeping open the cavities produced by the evolution of gas. The coating is spread on paper which is preferably thickly sized, and is sensitized with an aqueous or aqueous-alcoholic solution of an alkaline bichromate. After drying and exposure a visible image is obtained and is developed in hot or cold water and decolourized in dilute hydrochloric acid giving the spongy layer. A powdered pigment mav be dusted on the layer and cam be transferred by slight pressure on to a sheet of paper coated with adhesive, or the pigment may be fixed on the original print. The paper can be used for superposing colour images in the threecolour process. The Specification as open to inspection under Sect.. 91 (3) (a) comprises also the production of an etching by pressing the developed and dried image layer against a plate of sufficiently soft metal.

Title: Improved method of making thermal insulation material
IPC: C08J9/14
Filed: 1958-04-23
Abstract: In making foamed polyurethane thermal insulation material, components capable of forming a polyurethane without evolution of carbon dioxide are employed, and the reaction to polyurethane is carried out in the presence of a liquid which vaporizes to give a gas inert to polyurethane and of thermal conductivity less than that of carbon dioxide.  The liquid is exemplified by halogenated hydrocarbons of b.pt. in the range 40-140 DEG  F., e.g. trichloromonofluoromethane and trichlorotrifluoroethane.  The material may be formed between the inner and outer body panels of a refrigerator cabinet.  An example is concerned with reacting a water-free polyester of hydroxyl No. 430 and acid number 1.5 with toluene diisocyanate, mixing the product with ethylene glycol, dimethyl ethanolamine, polyoxyethylene sorbitan monopalmitate as emulsifier and liquid trichloromonofluoromethane, and allowing attainment of a temperature of 250 DEG  F.  A comparative example describes the production of a carbon dioxide-filled foam.  Foams may also be made from reaction products of polyisocyanates with castor oil, glycols, diamines, polyesteramides and polyalkylene glycol ethers.ALSO:In making foamed polyurethane thermal insulation material, components capable of forming a polyurethane without evolution of carbon dioxide are employed, and the reaction to polyurethane is carried out in the presence of a liquid which vaporizes to give a gas inert to polyurethane and of thermal conductivity less than p  that of carbon dioxide.
