Class 29 An absorption refrigerator cabinet comprises superimposed refrigerating units which share a common heating channel and heating means are disposed at the lower end of the channel. Preferably the absorbers and condensers of the two units share a common cooling air channel. As shown in Fig. 1 two identical refrigerated compartments are superimposed on a pedestal 3, the arrangement being such that air is drawn into the heating and cooling channels through apertures 4 in the pedestal and the heater is accessible from the front of the cabinet by opening the drawer-like mounting 5. To conserve heat in the heating channel the heat transmitted to the lower generator may be inhibited as (Fig, 4) by surrounding the heater flame with a tube spaced from the walls of the heating channel; additionally fins 17, 18 (Fig. 6) extend into the channel from the points of contact of the upper generator 14 and pump 15 with the heating channel. As shown in Fig. 9 the two compartments are integrated into one cabinet and are separated by means permitting heat exchange to take place between the compartments e.g. a container 14 accessible from the top compartment, a sliding drawer, or perforated or glass shelves. A separate door may be provided for each compartment or only a single common door. The cabinet shelves may be perforated to allow free air circulation.

Abstract: 1,036,588. Printing surfaces. ROTARY PLATES Ltd. July 9, 1964 July 10, 1963. No. 27395/63. Heading B6C. A relief printing plate such as an electrotype and which is to be fitted to a cylinder is curved or bent to shape whilst in contact with a complementary member which supports and fills the non-printing areas of a plate, the member being stripped from the plate after the bending operation. In one method, after an electrotype is formed and backed in the usual manner, a complementary member is made by placing a fibre-reinforced thermosetting phenol-formaldehyde resin in sheet or particulate form over the plate and applying pressure by platens to cure the resin. According to a second method, the backed-up electrotype mould is used as the complementary member. After forming the mould 4 of vinyl chloride, vinyl acetate copolymer from an original in the usual way it is provided with a plane outside face 9 merely by planing if thick enough, or by using a filling 8, e.g. of a suitable polyester or epoxide resin with a curing agent, and planed. The electrotype 10 is formed on the mould 4 and backed as at 11 and the composite article is passed through a bending machine. The complementary member may be attached to the electrotype by adhesive, or the original may be etched at its surround to form keying dots in the plate and the complementary member, slipping thus being prevented during the bending operation,

Abstract: 1354641 Electrostatic separators PETROLITE CORP 12 June 1972 [19 July 1971] 27438/72 Heading B2J An electric treater for the resolution of emulsions comprises a vessel 11 with electrodes 13, 24; an entrance bushing 37 connecting an external high-voltage supply source, e.g. a transformer 36, to a conductor 38 associated with the electrode 24; and a conduit 39 leading from the bushing 37 to the interior of the vessel 11, the conduit including an upwardly extending portion 56 adjacent the vessel 11, an intermediate bight portion 57, and a downwardly extending portion 58 associated with a heat exchanger 59. In operation, the emulsion to be treated, e.g. a continuous phase of crude oil with an aqueous dispersed phase, is at a high temperature such as 350F but the provision of the bight 57 results in the creation of a thermal dam which prevents this hot liquid mixing with the cooler liquid, having a temperature about 100F, in the portion 58 of the conduit 39. The bushing 37 can thus function in a favourable temperature environment, conducive to a longer life. The conduit may include a further bight portion intermediate the bight 57 and the entrance bushing 37; further, the conductor 38 may be mounted in counterweighted contilever fashion from a support within the vessel 11 so that none of its weight is taken by the bushing 37 (Figs. 2 and 3, not shown).

Abstract: A foamed polymer comprises a three dimensional network of isocyanate-modified hydroxypolyalkyleneoxy ethers of tetramethylol-cyclohexanol, the polymer containing in th polymer network units having the formula: <FORM:0943265/C3/1> in which each R4 represents an ethylene or propylene radical and n is a number of value at least 2.  The foamed polymer is prepared by reacting the corresponding hydroxypolyalkyleneoxy ether with an organic polyisocyanate and foaming the resulting polymer by adding to it water and/or a blowing agent.  The ethers are prepared by reacting an alkylene oxide with tetramethylol cyclohexanol, to give products having molecular weights in the range between 450 and 10,000. Blowing agents and catalysts are listed.  The latter include inorganic and organic bases, phosphine, and various inorganic and organic arsenic, antimony, bismuth, titanium lead, copper and mercury compounds.  In examples (1) propylene oxide is reacted with 2, 2, 6, 6-tetrakis (hydroxymethyl) cyclohexanol in the presence of potassium t-butoxide. The adduct is mixed with dibutyl tin dilaurate, silicone oil surfactant and trichloromonofluoromethane. Mixed 2, 4- and 2, 6-tolylene diisocyanates are stirred in and the mixture is put in a mould to foam and cure; (2) water is used as a foaming agent; (3) reactants used are an adduct of tetrakis (hydroxymethyl) cyclohexanol with 10 mols each of ethylene and propylene oxides, dibutyl tin dichloride, silicone oil and trichloromonofluoromethane and tolylene diisocyanates. Examples (4) is similar to (2), but with the use of dibutyl tin diacetate and triethylamine as catalysts.  Clays, diatomaceous earths and aluminium powder are suitable fillers.
