Title: Improvements in or relating to greenhouse structures
IPC: A01G9/16
Filed: 1934-06-19
Abstract: 434,680. Glasshouses. RICARDO, H. R., Tottington Manor, Small Dole, Near Henfield, Sussex. June 19, 1934, No. 18135. [Class 20 (i)] A movable greenhouse is adapted to be supported on removable floats in troughs, so that it can be readily moved. The roof A, Fig. 1, is supported by end trusses C and girders C<1> from the sides B, the lower edges of which bear on plates E which normally rest on the edges of troughs F containing fluid, the structure being braced diagonally by ties N. When it is required to move the structure, the ties N are removed and the floats H are partially filled with water until they are submerged or the water from the troughs is evacuated and the floats are passed under the plates E ; the water in the floats is then pumped out or the troughs refilled so that the structure is raised and it can then be easily moved to a new position. The outside edges of the sides of the structure are level with the outer edges of the troughs so that the troughs lie within the structure and may be used as watering troughs for the plants. The edges of the roof structure may rest directly on the floats, or a flat roof structure may rest on floats in troughs raised on side walls. Projecting side roof portions without walls may be secured by placing the trough or troughs just below the centre of the roof or intermediately of the edge portions, the bearing-plates being then used as shelves for plants.

Title: Pulp board and method of making the same
IPC: B29C43/00
Filed: 1930-06-13
Abstract: 354,001. Drying pulp board. BECHER, H. L., P.O. Box 130, Trenton, New Jersey, U.S.A. June 13, 1930, No. 18226. Convention date, July 13, 1929. [Class 96.] Raw wood fibre, chemically digested wood fibre, newspaper stock, straw, bagasse, &c., pulped in a beater, moulded, &c., has the bulk of the water removed and is then subjected to heat to remove the interstitial water with substantially no applied pressure and then to heat and pressure to remove the water colloidally associated with the fibres. The resulting board may contain a binder such as montan wax, sulphur, shellac, mineral pitch, asphaltum, gilsonite, china wood oil, resins, lignins, sizes, &c. Heating is effected by steam-filled platens of a hot press at a temperature sufficient to soften the binder if a fluxing binder is used ; pressure is then applied, the board being thus prevented from warping, and being released when completely dry without cooling the platens. A wire screen on one or both sides of the board may be used to facilitate escape of water vapour. Specification 7301/08, [Class 96, Paper &c.], is referred to.

Title: Improved manufacture of varnishes, solid plastics and the like from sulphite waste liquor
IPC: C08G8/28
Filed: 1931-06-26
Abstract: A water insoluble condensation product soluble in alcohol and capable of being hardened is prepared by condensing together a phenol such as phenol, a cresol, cresylic acid, or xylenol, a material containing the characteristic solids of sulphite cellulose waste liquor and an added aldehyde such as formaldehyde or furfural, with or without the addition of acid catalysts such as hydrochloric acid or ammoniacal salts, particularly ammonium chloride.  The sulphite cellulose waste liquor may be treated to remove organically combined calcium such as by treatment with sulphuric or oxalic acids or with soluble sulphates or oxalates and filtering off the calcium precipitate.  In examples (1) sulphite waste liquor, phenol, and hexamethylenetetramine are condensed together and the product dissolved in a solvent may be used as a varnish.  (2) Lime free sulphite waste liquor neutralized with ammonia, phenol, and hexamethylenetetramine are condensed together and the product dissolved in alcohol.  Either the product or the solution may be mixed with a filler such as wood flour or asbestos, dried and then moulded under heat and pressure.  (3) Lime-free sulphite cellulose waste liquor, phenol, and formaldehyde are condensed together in the presence of ammonium chloride giving a resin soluble in alcohol and mixable with asbestos.  (4) Lime free sulphite liquor, phenol, and formaldehyde are condensed in the presence of ammonium chloride giving a resin which can be made infusible by heating.

Abstract: 931,371. Liquefaction of gases. UNION CARBIDE CORPORATION. May 29, 1961 [May 31, 1960], No. 19222/61. Class 8(2). In a process for liquefying a compressed feed gas having a boiling point below -80C at atmospheric pressure e.g., nitrogen wherein after preliminary cooling the compressed feed gas is liquefied in a path 35 of a liquefier 34 in countercurrent to a gaseous refrigerant, which may also be nitrgoen, at a temperature below the condensation temperature of the compressed feed gas, the refrigerant gas having been compressed and after cooled is expanded without liquefaction in a turbine 63 and the relatively warm refrigerant leaving the liquefier path 37 is used to cool the incoming feed gas and is returned to the refrigerant compressor inlet. As shown nitrogen is admitted through a duct 10 to a compressor 51a, cooled in a water-cooled exchanger 53, further compressed to 145 p.s.i. in a compressor 55, and after being cooled in a water-cooled exchanger 57 is divided into a feed portion and into a refrigerant portion which traverse paths 17, 57, respectively of a heat exchanger 16, paths 23, 59 of heat exchanger 22 cooled by an external refrigerant e.g., ammonia and paths 29, 61 of an exchanger 26 cooled by recycled refrigerant nitrogen in a path 31. The refrigerant stream of nitrogen is then fed through a duct 62 to the turbine 63, and thence to the liquefier path 37 where it condenses the feed stream in path 35 which discharges product liquid nitrogen through an automatic pressure control valve 41 into a receiver 72 having a vent duct 74 connected to the delivery duct 65 of the turbine 63. In liquefying a gas differing in boiling point to the refrigerant gas the two gases traverse separate circuits. In a modification the expansion of the compressed refrigerant gas is effected in two turbines in series.
