Title: Improvements in or relating to heat exchanging apparatus
IPC: B01D1/28
Filed: 1946-04-29
Abstract: <PICT:0646421/III/1> In a vapour compression evaporator in which the vapour evolved is compressed and passed back to a condenser within the still, vapour, or a mixture of liquid and vapour, evolved from liquid in a separate heater is passed to the same, or a second, condenser in the still, and a minor part of the condensate from the condenser is returned to the separate heater.  In a specific embodiment, Fig. 1, the cooling liquid jacket 11 of an internal-combustion engine 10 is surmounted by a casing 14 enclosing the exhaust manifold 13 and by a boiler 15 fitted with tubes 19 through which the exhaust gases pass.  The liquid in the jacket and casing intermixes with that in the boiler through holes 16, 161. The engine drives a compressor 26 which compresses vapour withdrawn from a still 25 before introducing it to the condenser 28 where, in condensing, it causes distillation of the liquid in the still.  The condensate is taken off by line 31, a minor part being taken through line 44 to boiler 15 and the rest, together with residual liquid taken from the still by line 32 may be passed through a preheater 42 to heat up fresh feed from supply tank 33. In distilling a liquid, such as sea-water, where the distillate may be used as engine coolant, the vapour of the coolant from boiler 15 or-if the boiler is operated in a flooded condition-a mixture of vapour and liquid, is admixed through line 48 with the compressed vapour entering the condenser 28 and a minor part of the condensate is diverted from line 31 to the boiler via line 44, the pumps 46, 47, being used to overcome resistance and maintain the pressure in the boiler equal to that on the exit side of compressor 26.  Where the distillate is not to come into contact with the engine coolant, the vapour or vapour/liquid mixture from the boiler may be passed through valve 53 into coil 57 and returned via pump 59.  Part of the feed may be preheated by passage through valve 37 or, after passing through preheater 42, through line 40 and valve 39, into coil 50, rejoining feed-line 34 by line 51.  In this event the boiler is preferably not operated in a flooded condition, the appropriate level being maintained by float valve 49.

Abstract: 653,085. Testing friction of driving belts. DUNLOP RUBBER CO., Ltd., and NORCROSS, T. May 11, 1948, No. 12851. [Class 106 (ii)] Apparatus for measuring the resistance to slip under static load of a pulley and a driving belt in order to adjust idler rollers to ensure that a number of pulleys will run at the same speed comprises a collar 1 fitted over the pulley shaft for testing when the pulley is stationary, and locked to the shaft by means of a set screw 2. A bracket 4 having a scale 8 is rigidly attached to the collar as shown in the Figure. An annular yoke 3 is mounted on the collar by means of a ball-race 9 and drives a rod 5 the end of which is shaped as a pointer moving across the scale. A spring 6 urges the pointer toward the left-hand stop 12 and a handle 7 is provided to exert the test force. When the pulley is at rest the collar is locked to the spindle under test and the rod 5 moved over the scale by means of the handle 7 to stretch the spring 6. When the spring tension is such that the friction of the driving belt on the pulley fixed to the spindle is overcome the pulley slips against the driving belt and the bracket moves. The position of the rod on the scale at this stage indicates the load required to overcome the resistance to slip of the belt and the pulley.

Title: Improvements relating to the fabrication of extruded thermoplastic articles
IPC: B29C48/05
Filed: 1944-07-07
Abstract: <PICT:0606880/IV(a)/1> Articles such as tapes or tubes are made by extruding heated thermoplastic material through a die 1, passing the material 2, while still hot, through a plate or series of plates 3, 4, 5, each having a contour determining opening, and supplying a coolant 11 to the extruded material between the material and the walls forming the openings in the plates.  The shape of the extruded product may be controlled by varying the distance of the first plate from the die and by producing a temperature gradient in the material. This temperature gradient may be produced by directing coolant to some portions of the material while restraining it from other portions, by directing coolant to one portion in advance of p  its application to another portion or by directing the flow of coolant along one portion of the material at a rate greater than the flow of coolant along another portion of the material.  For the production of tubing, an extruded tube is supported by internal air pressure while passing through the plates and the tube is finally drawn through an inclined draw-plate immersed in the coolant.  This method of producing tubing is also described in Specification 602,321.  The coolant may be water, glycerine, hydrocarbon oils, or a gas.  The openings in the plates may be of a different shape from that of the die and they may taper outwardly away from the die.  The material may be cellulose acetate-butyrate, cellulose acetate or nitrate, ethyl cellulose, benzyl cellulose, polymers of vinyl acetate, vinylidene chloride, styrenes or methyl methacrylate, copolymers of vinyl chloride and acetate or nylon type resins.

Abstract: 1,128,314. Wire coating process and apparatus. SIEMENS A.G. 24 March, 1966 [24 March, 1965], No. 13158/66. Addition to 1,063,899. Heading D1L. A process for coating a wire with a thermoplastic synthetic resin comprises a) drawing the wire through a thixotropic dispersion of the resin in a liquid such that the wire emerges from the dispersion in a vertical or substantially vertical direction, the viscosity of the dispersion in the region of wire emergence being reduced mechanically and b) heating the coated wire to fuse the resin; the reduction in viscosity is effected by shearing means comprising two parallel members separated by a spacer member, which members rotate or reciprocate in contact with the dispersion, the wire passing between the two members and the arrangement being such that the distance between the wire and the spacer member can be varied. The shearing means is preferably movable in a direction perpendicular to the direction of travel of the wire. The two parallel members are preferably two discshaped flanges integrally joined to a hub member, and the surfaces of the flanges may be roughened to prevent slip in the dispersion. Separate driving means may be provided to rotate or reciprocate the parallel members, the rotation preferably being in the opposite direction to that of the travel of the wire. The speed of rotation or reciprocation may be varied to vary the viscosity of the dispersion and hence the thickness of the coating applied.
