Title: Method and apparatus for reducing the liquid content of slidges
IPC: F17C9/04
Filed: 1971-07-13
Abstract: 1388405 Dewatering sludges WATER RESEARCH CENTRE 5 July 1972 [13 July 1971] 32735/71 Heading C1C [Also in Division F4] A method of reducing the liquid content (e.g. water), of a sludge comprises the steps of freezing sludge droplets by contact with an inert cooling liquid which is immiscible with the suspending medium of the sludge and thawing the frozen droplets. The sludge droplets may be formed in or outside the cooling liquid. The cooling liquid may be a cooled solvent, e.g. carbon tetrachloride, hexane and/or toluene, or a liquefied gas, e.g. n- or iso-butane, propane and/or butene. The frozen droplets may be thawed in the inert liquid or after separation therefrom. The droplets may be agitated, e.g. by mechanical means or gas, during the freezing and thawing steps. In the embodiment shown, sludge droplets from sprayer 7 are frozen in liquefied gas 20 in freezer 1 and the frozen droplets thawed in melter 2 by warm vapour supplied from freezer 1 via compressor 9, which vapour is condensed in melter 2. The resulting mixture is passed to vessel 3 where the liquefied gas is separated and returned to freezer 1. A dewatered sludge is separated from supernatant water in settling vessel 4. Any remaining traces of liquefied gas in the water are stripped, e.g. using vacuum or nitrogen, in stripper 5.

Filed: 1973-07-10
Abstract: 1384969 Television; multiplex systems HAZELTINE RESEARCH Inc 10 July 1973 30 Oet 1972] 32838/73 Headings H4F and H4L A system for compatibly transmitting and receiving both a television signal and a suppressed carrier additional information (add-on) signal within the same frequency band wherein a reference burst signal is transmitted with the combined signal this burst signal having a predetermined amplitude and being representative of the phase and frequency of the carrier upon which the additional information is modulated. At a receiver the add-on carrier is regenerated from the suppressed carrier add-on signal (e.g. by squaring the received add-on signal thereby producing the second harmonic of the add-on carrier, and dividing by two to produce the add-on carrier of the proper frequency but with a phase ambiguity) and the inherent phase ambiguity in this regenerated carrier is removed by comparing its phase with that of the received burst signal and altering its phase if there is a difference, e.g. if the phase of the regenerated carrier differs by 180 degrees from that of the received burst signal. The reference burst signal is preferably transmitted during selected blanking intervals, e.g. vertical blanking intervals.

Title: Production and recovery of polymers
IPC: C08F10/00
Filed: 1958-10-15
Abstract: Solid polyolefins are recovered from solutions thereof in a volatile solvent by continuously spraying the hot solution into a confined stream of cooler water and passing the resultant mixture, at sufficient pressure to keep the solvent and water liquid, through a confined zone, the residue time in the zone being at least 5 seconds, thus recovering the precipitated polyolefin in a non-fibrous particulate form of high bulk density. The polyolefin, e.g. ethylene or propylene, is preferably high density highly crystalline material prepared in the presence of a particulate catalyst comprising chromium oxide at least partly in hexavalent form, supported on silica-alumina.  The solution is preferably at a temperature of 270 DEG -310 DEG F. and the water at such a temperature that the resulting mixture is at 110 DEG -130 DEG F.  This mixture may be sprayed into a further stream of water in a confined zone and under sufficient pressure to keep the water and solvent liquid and then passed to a heated zone at a sufficiently low pressure for the solvent to evaporate.

Title: An improved forming and consolidating process for metals and metal carbides
IPC: B22F3/105
Filed: 1934-11-16
Abstract: <PICT:0452503/III/1> Solid articles are made from metal powders or metal carbide powders or mixtures thereof by subjecting the powder contained in a mould to the action of a field produced by an alternating current of high-frequency.  Part of the material may be in the form of granules or turnings.  The action may be carried out in the presence of inert gases such as argon, krypton or neon, or of hydrocarbons to effect carburizing, or of ammonia to effect nitrogenizing.  The action may take place under pressure, the gaseous atmosphere being also under pressure, if desired. Articles having bores, holes, cavities or recesses may be formed by the use of a vaporizable core such as of borax.  Articles may be made by this process of an alloy comprising 80 per cent of metals of groups V and VI and 20 per cent of silver.  An apparatus for producing a draw plate comprises a fireclay vessel wound with a coil 7; within the vessel is a ceramic mould 3 in which the powder 5 and a borax core 6 is placed, a lid 4 being placed thereon.  Neon, at a pressure of 10 atmospheres is passed through the apparatus.  Tools, tool parts, valves, valve parts and injection nozzles for internal-combustion engines may be made.

Abstract: 489,415. Weighing-apparatus fitted to apparatus for treating granular material. WESSANEN'S KONINKLIJKE FABRIEKEN N. V. Dec. 1, 1937, No. 33209. Convention date, Dec. 18, 1936. [Class 143] A device for continuously determining and if desired registering the efficiency of treatment to which a granular or powdered substance is subjected is characterized by one or more automatic weighing devices 1, 2, 3 and 4, 5, 6 for the raw and treated product respectively which weighing devices control devices (oil pumps 14, 21) for supplying quantities of oil, proportional to the weighing results, to two separate tanks 20, 23 provided with outlet devices (needle valves 24, 30) interconnected (by piston 29) in such a manner that the outlet passages are always equal to one another, the tank 20 being provided with a float 26 for maintaining a constant head and the other tank 23 being provided with a device for indicating the liquid pressure in the outlet opening 30 or a value proportional thereto. Each weighing device is provided with a pair of electric contacts 7 which energize electromagnets 9 each time a unit of weight is passed. Each electromagnet operates a corresponding slide 10 to admit oil supplied by a pressure pump 15 to one side of the piston 13 and causes oil (proportional to the unit passed by the weighing device) to be expelled by the other side of the piston into the tank 20 corresponding to the raw material, or into the tank 23 corresponding to the treated product. The height of the oil in the tank 20 is maintained by the float 26 which by means of a servo-motor 27 connected to the pressure pump 15, controls the passage of the excess oil through the needle valve 24. The needle valve 30 is at the same time opened to a corresponding extent to adjust the level of the oil in the tank 23. The square root of the head h<1> of oil in this tank is proportional to the weight of the final product passed through the weighing devices 4, 5, 6 and may be read continuously in any convenient way by means of an indicating device such as the pressure-actuated dial 31.
