To facilitate the extrusion of rods of circular or other cross-section from one of the following thermoplastic materials, polyamides, polyethylene, polypropylene, polyformaldehyde and polymers of trioxane, a wedge or cone-shaped mandrel 9 is provided which projects forwardly of the extrusion nozzle 7 within a cooled die 2. It is said that when extruding the above mentioned plastics materials a cone (4), Fig. 1 (not shown), of molten material is formed, whose conicity (α) depends on the rate of solidification and the draw-off rate, and that when (α) is small, voids, internal stresses and deleterious gelling occur within the rod. With the provision of mandrel 9 together with cooled die 2, the conicity is maintained at a relatively large value and only a relatively thin walled cone of melt occurs surrounding the mandrel. In a second embodiment, Fig. 3 (not shown), the extrusion occurs vertically downwards without applied pressure in the extruder, the die (2) is provided with suction ducts (21) and an additional cooling ring (24) is provided. As a thermal barrier a knife edge contact 15, Fig. 2, between die 2 and the extrusion nozzle may be provided or alternatively a ring (23), Fig. 3 (not shown) or a disc of heat insulating material such as asbestos or a polyfluorocarbon.

Abstract: 1486436 Defrosting UPO OSAKEYHTIO 7 Nov 1974 [8 Nov 1973] 48306/74 Heading F4H [Also in Division H2] A refrigeration unit includes a device for controlling the formation of ice on the cooling element of the unit which device comprises a mains supply adapter 1 feeding current via an oscillator 2 into a light emitter 3 which emits pulses 13, preferably within the infra-red range, to a light receiver 4 controlling a comparator circuit 5 which via a relay 6 in its rest position connects power to the refrigeration circuit or in its picked position to a defrost resistance heater 9. A thermostatic switch 10 controlled by a sensing unit 11, e.g. a resistor having a negative temperature coefficient, at the cooling element of the refrigeration unit, stops the defrosting action by resetting the comparator circuit and hence the relay 6 to its rest position. As shown, frost 12 formed on the cooling element reflects at least part of the emitted light to the receiver to actuate the control device. In a further embodiment, the relay 6 may be replaced by a switching circuit, for example including thyristors.

Title: Production of potable water from sea water
IPC: C02F1/06
Filed: 1965-11-15
Abstract: 1,093,440. Distillation of sea water; prevention of scale formation. A. CHECKOVICH. Nov. 15, 1965, No. 48350/65. Heading B1B. To prevent scale formation on heat exchanger surfaces in a multi-stage flash evaporation system used for producing potable water from sea water the carbon dioxide which is released during the flash evaporation is recycled to the sea water prior to its pre heating before the flash-evaporation, so maintaining the concentration of dissolved carbon dioxide in the water at a level sufficient to inhibit the hydrolysis of bicarbonate ions to carbonate ions. When extremely high temperatures are used, e.g. above 220‹F, acid may be introduced into the sea water to reduce the total carbonate alkalinity to below 100 p.p.m. Sea water is supplied through line 10 and sprayed into an absorber tank 31 into which carbon dioxide together with other non-condensible gases from the flash stages 60-64 is introduced through lines 24 and 25. Non- condensible gases are removed through line 13 by a pump 19 which also maintains a pressure in tank 31 sufficient to ensure solution of the CO 2  in the sea water. The treated sea water is transferred via line 48 through heat transfer coils 32-36 for pre-heating while serving to condense flashed vapour to fresh water. The pre-heated water then flows to a steam heater 37 where its pressure is controlled at a little above saturation temperature by valve 11, the pressure being read on an indicator P.I. The treated and heated water then flows through the flash stages 60-64, the condensate being collected in wells 64a and removed through line 50. Extra bottled CO 2  or acid may be introduced through line 56. Acid may also be added to the inlet line 10 or at points X between the flash stages. Fig. 2, not shown, illustrates a multi-flash system in which a portion of the concentrated sea water is recycled together with fresh sea water which has been de-aerated, the mixture being passed through the carbon dioxide absorption tank prior to heating.

The low-pressure compressor 3 includes a main rotor 4 and a gate rotor 5 secured to shafts 59, 60 and furnished with teeth 76, 86, these rotors being rendered hollow so as to be dynamically balanced. The profiles of the rotors are described with reference to Figs.6 and 9 (not shown). The rotor surfaces may be coated with a material e.g. paint, that can be partially worn away so as to ensure adequate sealing. Inlet and outlet passages 68, 71 for the working fluid communicate with corresponding ports 69, 70, 72 formed in a housing portion 50 and end walls 52, 53. The ports 70, 72 are formed in each of the end walls, the ports 72 being controlled by the rotor 5. Whereas the housing 50 is air cooled the end walls are cooled by oil stored in a casing 84 for synchronizing gears 9, 10. The high-pressure compressor 2 is identical to the compressor 3 saving that it is smaller. A flange 45 can be used to attach the unit to the motor or engine. The compressor 3 may be replaced by an intermeshing-screw compressor. The unit may comprise a further intermeshing-screw compressor to effect an intermediate stage of compression.
