Title: New guanidine derivatives
IPC: A01N47/44
Filed: 1961-07-26
Abstract: The invention comprises cyclododecylguanidine and its organic and inorganic salts, such as the acetate, hydrochloride and sulphate. The novel compounds may be made by heating cyanamide with an organic or inorganic salt of cyclododecylamine in an anhydrous solvent medium and, if desired, converting the salt of cyclododecylguanidine thus obtained into the base or another salt. The anhydrous solvent medium may be an aliphatic alcohol containing at least four carbon atoms, such as n-amyl alcohol, or an aromatic hydrocarbon, such as benzene or toluene, or a mixture of such solvents.  Preferably an excess of cyanamide is employed, and the solvent medium is removed during the course of the condensation by distillation.  The condensation may be effected at the boiling point of the reaction mixture. Cyclododecylguanidine may be obtained treating a salt with an aqueous solution of an alkali metal hydroxide, preferably at reflux temperature with simultaneous extraction with an inert solvent, e.g. benzene.  Inorganic salts may be obtained action of inorganic acids on an alcoholic solution of an organic salt of the base.ALSO:Parasiticidal compositions comprise cyclododecylguanidine or an organic or inorganic salt thereof, e.g. carbonate, nitrate acetate propionate, butyrate, valerate caproate, laurate, maleate phthalate, benzoate, hydrochloride, nitrate or sulphate, together with one or more diluents.  Preferably the compositions contain 0.5 to 95% by weight of the guanidine compound.  The solid compositions may be prepared by grinding the guanidine compound with a solid diluent, or by impregnating the solid diluent with a solution of the guanidine compound in a volatile solvent and evaporating the solvent. The guanidine compounds may also be used dissolved or dispersed in a liquid, i.e. in the form of aerosols, suspensions, emulsions or solutions in water, organic or aqueous media which may contain wetting, dispersing or emulsifying agents of the ionic or non-ionic type, for example sulphonicinoleates, quaternary ammonium derivatives or products based on condensates of ethylene oxide with, for example, octylphenol or p-isopropylphenol, or fatty acid esters of anhydrosorbitols condensed with ethylene oxide.  Self-emulsifying concentrates may be made by dissolving the guanidine compound in the dispersing agent or in a solvent containing a dispersing agent. Specified p  solid carriers are talc, calcined magnesia kiesulguhr, tricalcium phosphate, powdered chalk, absorbent clay or carbon black, e.g. kaolin or bentonite.  Specified liquid diluents are toluene, xylene, mineral oils or vegetable oils.

Patent GB-879283-A (GB)
Title: Preparation of solid olefine polymers
IPC: C08F10/00
Filed: 1960-06-23
Abstract: One or more olefines are polymerized in the presence of a substantially inert liquid hydrocarbon reaction medium having a mid-boiling point between 200 DEG  and 480 DEG F., and a solid polymerization catalyst, all or at least part of which is insoluble in the hydrocarbon reaction medium, to form a solution of normally solid olefine polymer in the reaction medium.  The polymer is recovered from the medium by flashing the solution at a pressure below the polymerization pressure to remove at least a major proportion of unreacted olefine monomer, physically removing solid catalyst, flashing the residual solution to remove a major proportion of the reaction medium and to leave a molten polymer, extruding the molten polymer to extend its surface, extracting the polymer with a paraffinic solvent to remove any residual hydrocarbon medium and any "grease," and lastly mechanically working the solvent-extracted polymer under subatmospheric pressure, e.g. by vacuum extrusion.  The process is operated continuously, and unreacted olefines and recovered reaction media are purified before recycling to the polymerization zone.  The olefine may be ethylene, propylene, butene-1, or mixtures thereof. The catalyst may be (1) an element or oxide of Group IV, V, VI, or VIII, of the Mendeleeff Periodic Table, e.g. titanium, chromium, molybdenum, or cobalt supported on silica, alumina, magnesia, titania, zirconia, or a clay, or (2) an oxide of one or more metals of Group IV, V, or VI of the Periodic Table in conjunction with an element, hydride, or organometallic compound of an element of Group I, II, or III of the Periodic Table, e.g. alkali metals, their hydrides, lithium borohydride, beryllium alkyls, diborane, aluminium triethyl or diethyl chloride, or (3) a compound formed by the interaction of a compound of Group IV, V or VI with an alkyl, aryl or sesquihalide of aluminium, magnesium or zinc, or with a Group I metal alkyl, e.g. titanium chloride or vanadium oxychloride with aluminium triisobutyl, or titanium trichloride with aluminium triethyl.  The paraffinic hydrocarbon used for extracting the extruded polymer contains from 3-7 carbon atoms, e.g. propane, butane, or cyclohexane.  The separation of the catalyst may be effected by filtration, e.g. through a cellulosic sheet, or by centrifugation, or electrostatic precipitation.  The Specification describes and illustrates, by a flow diagram, the continuous manufacture of purified olefinic polymers. Specification 748,634 is referred to.

Patent GB-911810-A (GB)
Title: Ice making machine
IPC: F25C1/12
Filed: 1961-06-20
Abstract: 911,810. Ice-making. KATTIS, T. June 20, 1961 [July 22, 1960], No. 22224/61. Class 29. [Also in Group XXIV] An ice-making apparatus comprises a substantially vertically-disposed refrigerated plate 22, a grid member 31, Fig. 6, having a plurality of cavities A open at each side of the member, a motor-driven cam 51 (see Group XXIV) providing means for moving the member 31 into contact with the refrigerated plate, as shown in Fig. 5, and for moving the member away from the plate. Water to be frozen into " cubes " is pumped during the freezing cycle by a motor-driven pump 59 from a tank 58, via pipes 66 and 64 and a reservoir tank 65 to discharge into a trough 34 along the top edge of the grid member 31. Water then flows through slots 36 and V-notches 35 and over the face of the grid member 31 not adjacent the refrigerated plate 22, flowing into and out of the cavities with some of the water freezing in the cavities against the refrigerated plate. A surplus quantity of water above that which is frozen flows over the face of the grid member, returning to the tank 58 via a collector 37. The grid member and the refrigerated plate are respectively made of materials of relatively low and high thermal conductivity, so that ice tends to adhere to the plate and not the grid member. The refrigerating machinery comprises a compressor 80, a condenser 83, a receiver 86, an expansion valve 87 and mounted in intimate contact with the refrigerated plate on evaporator coil 70. When sufficient ice has been formed and the refrigerated plate falls to a predetermined temperature, a thermal bulb 96 actuates a switch which terminates the freezing cycle and starts the dispensing cycle. The condenser fan 84 and the water pump 59 are switched-off and the cam motor 53 and a solenoid-operated valve 89 are switched-on. The valve allows hot gases from the compressor 80 to pass directly to the evaporator coil 70, thereby melting a film of ice on the refrigerated plate 22. The grid member is moved away from the refrigerated plate on to ejector posts 57, after a pre-determined delay, thereby ejecting the ice " cubes " from the cavities A which fall through an opening 17 into a storage bin (not shown). So that the cubes" " are not dispensed all at once thereby blocking the opening 17, the posts 57 are of staggered length with the smallest in the middle. The grid member is then returned to the plate and the freezing cycle is restarted. During the dispensing cycle, water flows from the reservoir 65 back into the tank 58, thereby flooding a siphon pipe 69 which commences to empty the tank. Fresh water supplied by pipe 61 passes through a heat-exchanger 73 in thermal relation with water discharging from the siphon pipe 69. Discharge water is evaporated in a heated tank 75 having been discharged from the tank 58 faster than the inflow of fresh water controlled by a ball valve arrangement 63.

Title: Process for improving physical characteristics of resin foams and improved products thereof
Inventor: EBERL JAMES JOSEPH
IPC: C08J9/36
Filed: 1962-06-08
Abstract: A process of improving the physical characteristics of a low-density aminoplast resin foam comprises exerting at atmospheric pressure and humidity a uniform compressive force against the foam to reduce its volume without material destruction and subsequently removing the compressive force whereby the foamed body expands to substantially its original volume. The application and removal of the compressive force may be repeated, successive applications being of increased magnitude.  Urea-formaldehyde, melamine-formaldehyde and melamine-urea-thiourea-formaldehyde resins are referred to.  In an example, urea and formaldehyde in 1 : 2 molar ratio are reacted first in the presence of alkali and then of phosphoric acid until the product has a viscosity of 50 cs.  Urea, sodium secondary alkyl sulphate and water are added and the mixture is pumped together with a hardener comprising urea, phosphoric acid and water to a foaming nozzle to which compressed air is introduced while the mixed solution passes at high velocity along a tortuous obstacle path to produce a fine foam.  This is collected in wire mesh containers and cured at 80 DEG  C and 45% humidity in a cabinet with forced air circulation. Test blocks are compressed variously from 1 to 25 times by amounts from 30 to 80% for periods between one and 30 seconds and their softness and compliance properties are then determined. Specifications 768,562 and 773,809 are referred to.
