Title: Improvements in apparatus for boiling and distilling sea water
IPC: C02F1/04
Filed: 1964-03-23
Abstract: 1,039,307. Distillation of sea-water; cooling systems for marine engines. ATELIERS ET CHANTIERS DE NANTES, BRETAGNE-LOIRE. March 23,1964 [March 26,1963], No. 12217/64. Heading B1B. The heating chest 4 of a boiler 2 for the distillation of sea-water is heated by fresh water withdrawn through conduit 9 from the cooling- jacket of an engine 12, e.g. a Diesel engine, the coolant-water from the engine-jacket being further heated in heater 7, prior to being introduced into the heating chest 4, by heat-exchange with steam supplied to heater 7 through conduit 26. Having passed through the heating-chest of boiler 2, the fresh water is pumped back to the enginejacket through conduit 18. The steam given off by the boiling sea-water is condensed in condenser 1. The apparatus is suitable for a ship, for it makes possible the production of fresh water both when the ship's engine is in operation, and when the ship is moored. The steam supplied to heater 7 may be generated in waste-heat boiler 21 interposed in the exhaust pipe 20 of the engine, and/or the steam may be generated in mooring-boiler 29. Water of condensation is discharged from heater 7 via pipe 30.

Title: Improvements in centrifuging apparatus
Inventor: MCALOREN JOHN TERENCE
IPC: B04B1/02
Filed: 1958-04-17
Abstract: 896,032. Centrifugal strainer separators. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 16, 1959 [April 17, 1958], No. 12281/58. Class 46. A bulb 1, Fig. 1, impervious except for an open lower end 6 and one or more orifices 5, is dipped into liquid (containing solids) in a vessel having sides extending above the top of the bulb when only the tubular part 6 is immersed, and is rotated at high speed by a shaft 7. Liquid creeps up the inner wall of the bulb, passes through the outer regions of a filter disc 4 and is ejected through orifice(s) 5 to flow back into the vessel. Solids are retained by centrifugal force against the bulb sides and by filtration action against the underside of the filter disc 4. In Fig. 2 (not shown), the disc 4 is dispensed with but each orifice is covered on the inside by a filter disc. The bulb 15, Fig. 4, is open at the top but is push-fitted into a cup 18 provided with an adjustable shaft 20 having a vortexshaped end 26 co-operating with the inlet 16. In Fig. 3 (not shown), the shaft terminates just under the cup 18 and a plug of vortex-shape is positioned by bridges in the opening 16. When filtration is complete the bulb is raised, still spinning, and the solids are washed by dipping the spinning bulb in wash liquid in another vessel. The inner wall of the bulb may be roughened.

Title: Improvements in or relating to window-cleaning devices
IPC: A47L1/03
Filed: 1919-05-15
Abstract: 149,750. Gee, J. E. May 15, 1919. Windows and the like, cleaning. -A portable apparatus for cleaning both sides of a window at one operation comprises an arm on each side, in the form of lazy-tong sets A, B; C, D carrying at their outer ends rubbers M of wash-leather &c., movement given to one arm being communicated to the other so that the two rubbers follow the same path. The rubbers are normally held away from the window, and a connexion is provided between them so that both are moved towards or away from the window simultaneously. The links of the lazy-tongs are preferably of channel section to give rigidity, the channels being filled with blocks at the joints, as shown. One lowest link A, C of each arm is secured to a tube E, Fig. 2, fitting freely in an outer tube F to which the other links B, D, C are attached. The tube F is mounted in a cross member G, preferably of square section externally, which is fitted with a clamp H for securing the apparatus to the frame-member J of the window. The rubbers are held between plates M<1> mounted on tubular rods L, P slidable through the tubular pivots of the end links of the lazy-tongs. A spring N located between the links and a lug L<1> on the rod L, and, if desired, a similar spring on the rod P, normally hold the rubbers away from the window. The rod P is formed with a pressknob P<2> and a lug P<1>, and a Bowden-type flexible connexion Q extends from this lug P<1> to the lug L<1>. A finger-grip T is mounted on the end of the lazy-tongs C, D, so that the knob P<2> may be engaged by the palm of the hand to move the rod P and its rubber towards the window, a corresponding movement being transmitted to the rod L and its rubber. Provision may be made for adjusting the initial distance of the arms AB, CD from the window. According to the Provisional Specification, instead of the lazy-tong sets, rigid arms may be employed slidable in guides rotatable about the axes of pinions which gear with racks on the rigid arms, so as to secure the simultaneous movement of the arms. In the case of lazy-tong sets, these may be hinged on opposite sides of the pivoting sleeves so that they may be swung towards or away from the window, movement of one set being transmitted to the other set by a rigid rod passing through the innermost sleeve.

Title: Novel polycarbonate resins and process for the preparation thereof
IPC: C08G64/10
Filed: 1966-03-21
Abstract: New polycarbonates are made by reacting phosgene with a bisphenol of formula <PICT:1095963/C3/1> where R and R1 are hydrogen atoms, methyl groups or ethyl groups.  Reaction may be effected by solution polymerization in the presence of a tertiary amine and an inert organic solvent for the polycarbonate or by an emulsion polymerization in the presence of an aqueous solution of an alkali metal hydroxide and an organic solvent.  Specified solvents are trichloroethylene, methylene chloride, chloroform, ethylene chloride, chlorobenzene and mixtures of these chlorinated solvents with benzene.  The emulsion polymerization is preferably effected in the presence of a catalyst which is a quaternary ammonium, phosphonium or arsonium hydroxide or halide.  The catalyst may be added prior to, during or after the phosgene addition. When the onium catalyst is introduced after partial phosgenation, additional alkali may be added.  At the end of the emulsion polymerization the reaction mixture is acidified and the polycarbonate recovered from a solution by distilling off the solvent or by precipitation with a non-solvent.

Title: Improved method and means for producing filter layers on filter bands
IPC: B01D33/00
Filed: 1957-04-18
Abstract: 820,091. Filtering liquids. GENERAL ENGINEERING CO. A. B. April 18, 1957 [April 25, 1956], No. 12785/57. Class 46. [Also in Group XXVIII] In producing filter layers of definite thickness on filter bands, particularly on filter drums, the concentration of the filter liquid, such as a fibre suspension, which is to form the filter layer, is varied in dependence upon the speed of the filter band in the liquid to be filtered so that the layer remains approximately constant in thickness independently of variations in the speed of the band. An endless wire mesh band 6 passes around a filter drum 3 in a receptacle 1, over a guide roller 19, around a smaller filter drum 36 and around a filter discharge roller 30. The drum 36 cooperates with a partition 38 to divide an applying vat into two chambers 39, 40, the part 39 containing a suspension of fibres which are to form a filter mat on the band 6. To produce this suspension, the drum 3 drives a dosing device comprising buckets 9 adapted in turn to deliver concentrated fibre suspension to a discharge vessel 15 whence it flows into a mixing bat 16<SP>1</SP> to be pumped into the chamber 39. As the dosing divice is driven from the drum 3, the speed of the drum determines the concentration of the fibre suspension and consequently the thickness of the filter mat. Liquid to be filtered is maintained at a level 7 in the receptacle 1 and filtered liquid inside the drum at a level 8. The filter mat is removed from the band 6 by the discharge roller 30 and scraped therefrom by a doctor 31. A jet of water 32 cleans the band after the removal of the filter mat. A valve may control the rate of flow from the discharge vessel 15. In another form, the filter drum 30 is omitted and its functions are taken over by the guide roller 19.
