Title: Distillation method and apparatus
IPC: B01D3/02
Filed: 1966-11-18
Abstract: Liquid is distilled by partial vaporization of the liquid from a layer thereof, causing the vapour to diffuse through a microporous membrane which is impermeable to the liquid, and condense in a layer of distillate liquid on the opposite side of the membrane, the distillate layer being maintained at a higher hydrostatic pressure than the distilland layer.  The method is particularly applicable to the desalination of water by distillation in the multiple effect apparatus claimed in Specification 1,096,678, the necessary pressure-differential being maintained by connecting the distillate liquid withdrawal conduit to a standpipe located at the necessary height above the still.  The inlet and discharge conduits for the feed liquid and residual distilland respectively, may be connected to shorter standpipes.  The microporous membrane may be made of polyvinyl chloride, nylon, polytetrafluorethylene, or a cellulose derivative, coated with a silicone water-repellant.

Filed: 1967-11-21
Abstract: 1,247,340. Trays. B. M. MARCAN. 20 Nov., 1968 [21 Nov., 1967], No. 52960/67. Heading B8P. A tray for garden produce has a rectangular base with a wall extending upwardly from each side thereof and elements applied to the four corners thereof for supporting a second identical tray placed on top, each such support element consisting of a one-piece moulding of synthetic plastics material applied as a push fit over the tops of the end portions of two side walls where they meet in a corner and so that once applied they cannot readily slip off the walls: In a first construction, Fig. 2, the tray is collapsible in that the side walls 1 thereof can be folded flat on to the bottom 2, both the walls and the bottom being formed with strengthening ridges 3. The side walls are connected together at the corners by detachable means each of which consists of a main outer part 4 which is L-shaped in cross-section and which has on the free vertical edges thereof inwardly directed flanges 5 which, in use, engage in vertical grooves 6 formed in the walls 1 near the opposite ends thereof to prevent the elements slipping off the walls; inside the part 4 near the upper end thereof is a horizontal shelf 7 and depending from the free inner edge thereof is a vertical web 8 the side edges of which lie within but do not touch the flanges 5; the web 8 is deeper than the main outer part 4 and is supported by a diagonal web 9 which extends from the angle of the main outer part 4 to the centre of the web 8. A second construction is described in which the tray is made of cardboard with four sides and a bottom, the sides being connected by corner elements which are a modification of that described above in that for each corner element the webs 8 and 9 are omitted and instead a part which is L-shaped in cross-section depends from the shelf 7 so that deep grooves are provided. The vertical edges of the inner part are spaced from the flanges 5 so that when the element is assembled to the side walls the cardboard is distorted. In a third construction, the tray instead of having side walls which can be folded flat has side walls which incline towards the bottom so that the trays can be nested one inside the other and at each corner a detachable cap element is provided; each cap element is of triangular shape having an L-shaped groove in its underside for receiving the side walls with a tight push fit and a recess 34 in its upper side for locating the bottom corner of a like tray placed on top. Except for the tray which has a cardboard bottom and walls, the various parts can be made from synthetic plastics material.

Title: Telephone apparatus comprising a plurality of subscriber stations connectable to a two wire line
IPC: H04M9/00
Filed: 1974-12-09
Abstract: 1494749 Automatic exchange systems WESTERN ELECTRIC CO Inc 9 Dec 1974 [12 Dec 1973] 53236/74 Heading H4K A plurality of key telephone substations are each provided with visible signalling means comprising LED's or liquid crystal displays in respect of each of the exchange lines to which they have access, the means being in series with one line wire on the exchange side of the station and being arranged to flash in response to ringing signals and light steadily under off hook and hold conditions. The signalling means may present different colours in different modes of operation. As shown the LED's, 1LED-1, 2LED-1 and 3LED-1 associated with exchange line L1 in the three substations S1, S2, S3 are effectively in parallel with each other via internal bus 110, and in series with ringer 101, so that they will each flash in response to A.C. ringing on line L1. If any station goes off-hook thereby providing a D.C. path through the associated transducer/dialling network 102, 202 or 302 (switch-hook contacts SH operated, line key contacts PU-1 in their back condition as shown), the line current serves to energize each of the lamps steadily. If the answering station goes on hold by closing contact (B) (this is common for all stations) the line current continues to flow steadily through the lamp and the hold relay in series. A non-linear resistor 2V1 may be shunted across the LED's to protect them from line surges. It is pointed out that use of bipolar LED's renders unnecessary the use of bridge rectifiers for line polarity compensation. The use of two colour LED's is shown in Fig. 3. A.C. ringing on line L1 passes through the Red section of 4LED-1 and the ringer 401 in series and additionally passes through the Green section of this LED and an A.C. bypath 4R3, 4C 1 in series whereby a flashing yellow signal is provided at each station. Upon going off-hook (SH operated 4PU-1 back) the Red portion only of the LED glows steadily. During operation of the hold key (contact 4B-1) prior to release of the 4PU-1 contact set and making of the 4PU-2 contact set, both portions of the LED are illuminated so providing a steady yellow signal. When the line pick-up key is eventually actuated only the Green portion of the LED passes current.
