Title: Processes, apparatus and systems for separating a solvent in substantially pure formfrom a solution
IPC: C02F1/22
Filed: 1962-10-24
Abstract: 1,027,064. Concentrating solutions by freezing. DESALINATION PLANTS (DEVELOPERS OF ZARCHIN PROCESS) Ltd. Oct. 24, 1962 [May 16, 1962], No. 40286/62. Heading F4H. [Also in Division B1] In a flash evaporative solution purification process additional ice is formed, by direct or indirect contact with a refrigerant, either in the solution before it is flash evaporated or in the concentrated solution leaving the flash evaporator to make more ice available for condensing vapour produced in the evaporation step. As shown, sea water from an inlet pipe 10 is passed through a deaerator 12 and a heat exchanger 16 to a cooling unit 63 in which part of the solvent is frozen, the brine-ice slurry being then supplied through a pipe 18 to an evaporating chamber 20 where more ice is formed. The unit 63 comprises a cylinder having refrigerant passages formed in its walls, which are corrugated, and a rotary scraper for removing ice from said walls (Figs. 3 and 4, not shown). Water vapour is withdrawn from the evaporating chamber 20 by a centrifugal compressor 54 while the resulting ice-brine slurry is passed through a line 25 to a washer 26. The ice forms a rising column in the washer and is washed with product water supplied to the top of the column through a spray 38, waste brine being expelled through a filter 28 into a collecting chamber 32 from which it is pumped through a line 78 to the heat exchanger 16. Part of the brine in line 78 is supplied through a line 86 to the evaporating chamber 20. A scraper 34 at the top of the washer 26 supplies the ice to a vacuum chamber 36 where product water from a line 42 is added, the ice-water mixture being then supplied by a pump 44 through line 46 to an annular condensing chamber 50 which is defined between the evaporating chamber 20 and an insulated jacket 52. The ice in the chamber 50 is contacted with the vapour from the outlet 58 of the compressor 54 thus melting the ice and condensing the water vapour to form product water which is withdrawn by a pump 60. Part of this water is supplied through line 40 to the spray 38, part through line 42 to the chamber 36 and the remainder to the heat exchanger 16 through line 62. The water leaving the heat exchanger is supplied through a line 80 to a storage tank 82 from which it may be withdrawn by a pump 118 and supplied through a line 119 to cool and lubricate the motor 120 of the compressor 54. Water is returned from the motor to the tank 82 through line 121. In one modification (Fig. 5, not shown) the auxiliary ice-making unit 63 is located in a bypass line which receives part of the brine from the line 18 and supplies ice and brine from the unit 63 to the bottom of chamber 20. Alternatively, the unit 63 may be included in the icebrine discharge line 25 from the chamber 20 (Fig. 6, not shown).

Abstract: 1410589 Valves; linkwork SERCK INDUSTRIES Ltd 13 Sept 1972 [28 Aug 1971] 40445/71 Headings F2V and F2K [Also in Division G3] A butterfly valve spindle carries an actuating member 14 which supports a freely-rotatable weighted arm 17. In the position shown, arm 17 contacts stop 19 on member 14 and holds the member against stop 21 to maintain the valve open. When the arm is moved over-centre, e.g. by a diaphragm 23 controlled by a pilot valve 24 responsive to pressure downstream of a pressure regulator, it falls freely until it abuts stop 20 on member 14, and, it then rotates the member to close the valve, the closed position being defined by engagement of stops 21, 22. The valve may be upstream of the pressure regulator and reset manually by raising arm 17.

Abstract: 1481233 Electro-photography KONISHIROKU PHOTO INDUSTRY CO Ltd 18 Sept 1974 [19 Sept 1973] 40624/74 Heading G2H Reusable photo-conductive material A is tensioned around part of the surface of a drum, and is  advanced from supply reel 15 around the surface to take up reel 18 when replacement is necessary. When the supply in reel 15 is exhausted the drum is removed laterally from its mount, an opening portion of the body 16 is removed and arcuate cover 17 is raised to facilitate the fitting of new reels. The cover 17 is lifted bodily, without rotation, and is held by a frame while the remainder of the drum is rotated to a convenient working position. When the photo-conductive material A is advanced the cover .17 is lifted slightly to release the pressure which it exerts on the material A. At other times the slots through which the material A emerges from and enters the drum body are kept closed by the cover to prevent dust from getting into the drum interior.

A hole measuring device for gauging and recording the straightness of an elongated hole or passage, includes a body 20 adapted to be moved along said hole or passage 32, three measuring units 10 arranged one adjacent each end of the body and one in the middle of the length thereof, each measuring unit having feeler means 26 extendable laterally from the body and adapted to engage the wall of the hole or passage, and recording means 54, 60, 63 operated by the feeler means so as to make a record, at any predetermined position of the device in the hole or passage, of the lateral clearances between the body, adjacent the ends and in the middle thereof, and said wall. Each feeler 26 has connected thereto a styli 63 towards which the record bearing means 54 are moved in response to the motion of the device in the hole to make an indication on the strip 54 of the position of the feeler. The record bearing means is in the form of four drums mounted on a carrier 43 and each covered with indicating strips. The carrier is moved up and down by the motion of a wheel 34 which when it rotates anticlockwise forces rod 36 and hence carrier 43 upwards. Each recording drum has seven faces at which the styli can make an indentation and hence seven measurements are normally made at predetermined positions along the passage. As the carrier moves away from the styli by moving the device into the channel a ratchet 60 on each drum engages a pawl 62 which rotates the drum to its next indentation receiving face ready for the next measurement.

Abstract: 996,012. Phase separator. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. Nov. 23, 1962 [Nov. 23, 1961], No. 42011/61. Heading B1D. A phase separator comprises a chamber 4 having an inflow conduit 14 connected thereto, first and secopd outflow conduits 8 and 16 connected respectively to the lower and upper parts of the said chamber and a delivery conduit 18 for substantially uncontaminated phase flow and leading from the central portion of the chamber. The first outflow conduit 8. and the delivery conduit 18 may be provided with valve means controlling the flow therethrough. As shown, the volume of the chamber is such that the flow rate therethrough is considerably. lower than that through the conduits so that phase separation takes place more readily in the chamber. Baffle means 17 are located in the chamber to assist the phase separation, and gas bleed vent means 15 are provided. In operation, the contaminated liquid phase (either mainly aqueous or mainly organic) enters through inflow conduit 14 to the baffle 17 in chamber 4 where the contaminating phase separates, any entrained gas passing out of the gas tube 15. The heavier phase, including any solid matter, flows away through conduit 8 while the lighter phase flows away through conduit 16. The decontaminated liquid phase leaves the chamber via outlet 25 and the annular space between rod 20 and tube 13 and flows out of the delivery conduit 18. Manipulation of rod 20 to control the effective area of orifice 17 ensures that the heavier phase is present at the level 18 if so desired. Solid contaminant collecting in the base of chamber 4 is flushed away by raising the knob 20 from time to time to pull the tip 24 through the orifice 7.
