Liquid, e.g. sea water, is partially evaporated while flowing upwards through a series of flash chambers 25 disposed at increasing elevation in evaporator 11, and the vapour evolved in each flash chamber is condensed by direct contact with condensate flowing down through the condensation chambers 26 on the opposite side of the longitudinal partition 12 to the liquid being evaporated. The evaporator 11 is divided into five stages by baffles 13. Feed liquid, introduced through pipe 2, is mixed with part of the concentrated liquor withdrawn from the uppermost stage, and the mixture is pumped through heat exchanger 6 into the lowest stage via pipe 1. Condensate is withdrawn from the lowest stage through pipe 7 which passes through heater 9 and heatexchanger 6. Some of this condensate is disoharged through pipe 10, and the remainder is pumped back to the uppermost stage via cooler 8. Concentrated liquor is withdrawn from the system through pipe 3.

Filed: 1957-06-06
Abstract: 816,271. Earth-boring apparatus. LONGYEAR CO., E. J. June 6, 1957, [June 15, 1956], No. 18013/57. Class 85 A rotary core drill comprises a drill string 10, a sleeve 11, a wear coupling 12 having hardened lands 14L, a core barrel inner tube assembly 50, a hanger and valve coupling 17, core barrel outer tube 18, a reamer 19 and a bit 20. The assembly 50 is suspended from the coupling 17 and encircles the stem 66A of a bearing element 66 having a core lifter 75 screw threaded thereto. When the core lodges in or fills the core tube 72 the assembly 50 tends to lift relative to the drill string and this movement is opposed by spring-loaded latch dogs 53A, 53B. A rubber collar 61 is disposed between the members 50 and 66 whereby relative movement between said parts will expand said collar to block the fluid supply passage A.S. To withdraw the core barrel inner tube the drill string is retracted, whereupon the collar 61 is unloaded and the core lifter 75 moves upwardly relative to a split ring 76 to break off the core. An overshot 83, 84 is then lowered into the drill string, the pawls of which engage the spearpoint 80E-80D of a bearing tube 60 with a coller 84 in alignment therewith. The sleeve 60 is slotted so, as it moves upwardly, it extends the dogs 53A, 53B, the sleeve being retained on the member 51 by a rivet 55. In a modification (see Figs. 8-13, not shown), the coupling 17 above referred to is lengthened and the assembly 50 is provided with a O-ring to prevent a blowback of the drilling fluid.

Title: Improvements in or relating to plasticising apparatus for the moulding of plastics
IPC: B29C45/74
Filed: 1943-11-03
Abstract: 606,879. Dielectric heating. COMMUNICATIONS PATENTS, Ltd., and YOULE, F. Nov. 3, 1943, No. 18206. [Class 39(iii)] [Also in Group V] To subject plastic material to high frequency heating prior to moulding, a plunger 3 forces the material between an inner torpedo shaped live electrode 16 and the inside surface of a metal tube 4 which acts as the earthed electrode. The material passes through holes 19 in a mica or ceramic carrier 18 and then between a live electrode 15 and the inner surface of a nozzle 10, which acts as the earthed electrode. The electrodes 15, 10 may be closer together at the nozzle to obtain maximum plasticity prior to moulding. The carrier supports a rod 17 to which are removably attached the live electrodes. The rod 17 is connected to a source of high frequency alternating electric current of at least 30 Mc/s. The tube 4 is also electrically connected to the source and these connections are made by means of a cable of the low loss concentric type. The energization of the electrode system may be timed with the movement of the plunger or may be continuous. Two or more parts of the electrode system may be supplied with different voltages. Additional heating means may be used. A mica or ceramic layer may be moulded around the live electrodes or it may be formed homogeneous with the carrier. Specifications 517,798, 572,425 and U.S.A. Specification 2,179,261 are referred to.

Abstract: 561,785. Heating air and gases. STILL, W. J. Dec. 25, 1942, No. 18373. [Class 64 (iii)] [Also in Group XXII] Coiling ; rolling.-In a heat transmitting be of the kind in which heat conducting wire round spirally into an elongated coil which itself spirally wound round the tube, the wire forming the elongated coil is of oval or flattened cross-section in a sense transversely to the plane of the individual loops so as to reduce the resistance to the air flow past the tube. The outer ends 2a of the loops of the spiral are bent to a small radius, the sides are convexly curved and the inner ends are flattened as at 2b. The element is formed as described in Specification 314,843 [Class 83 (iv)] by spirally winding a wire round a fixed mandrel into elongated loop form and in the same operation spirally winding the elongated coil on a revolving tube, the wire being bound by a binding wire 39 and spot soldering and being supplied in wound form as usual so that the twisting of the wire which occurs between the stationary hank and the winding head takes place when the wire is round, the wire being flattened at a point between the twist and the winding head so that the flattened wire is fed to the winding head with the major axis of its cross-section always approximately parallel with the axis of the mandrel. The wire 15 is led from the hank through a mechanism having a hollow shaft 3 attached to the winding head, the shaft being coupled to one end of a rotary frame 4, the other end of which has a coaxial extension 5 passing through a bevel wheel 6 which may be stationary. The bevel wheel engages a bevel wheel 7 on a shaft 8 carried by the frame, this shaft carrying a pinion 9 engaging a pinion 10 so as to rotate the grooved roll 12 of a pair of feed and flattening rolls 12, 13 during rotation of the frame 4. The idle roll 13 is mounted on an eccentric portion of a pin 14 which may be adjusted to vary the pressure and held in position by a nut 21. The speed at which the rolls feed the wire is made slightly greater than that at which the wire is received by the winding head so that the helix is slightly loose on the mandrel. The feed may be varied by using instead of a fixed bevel wheel 6 a bevel wheel which may be connected by replaceable gears to the extension 5 so that it may rotate in the same direction as the frame or in the opposite direction thereto. Specification 271,122 [Class 64 (iii)] also is referred to.

Abstract: 459,209. Valve circuits for wireless reception. COLE, Ltd., E. K., Priory Crescent, Southend-on-Sea, BRADFIELD, G., 34, St. Benets Road, Prittlewell, Essex, and INSKIP, F. A., Trelawney, Carlingford Drive, Westcliff-on-Sea. July 1, 1935, No. 18711. [Class 40 (v)] The selectivity of a radio receiver is varied inversely as the signal strength by varying the effective coupling of an intervalve transformer which is provided with an auxiliary winding by which a reverse coupling effect is introduced. As shown, the valves V1, V2 are coupled by a tuned transformer P, S which also comprises auxiliary windings P1, P2 which are coupled in such a way that, with weak signals, the tight coupling between coils P, S is neutralized. The effectiveness of the coils P1, P2 is controlled by the impedance of the triode A1 which is dependent on signal strength, its cathode being connected to the cathode Y of valve V2 which is A.V.C. controlled. The coil S is also shunted by a triode A2, which has a grid and cathode common to those of A1, and is therefore controlled in impedance by signal strength. The valves A1, A2 act in parallel as a low frequency amplifier being fed from the point U in the circuit of the detector D2 and feeding an output transformer T1. In another embodiment, the valves A1, A2 are replaced by diodes, dry rectifiers or Thyrite resistances as described in Specification 292, 110, [Class 37].
