Title: Light-emitting or reflecing signs
IPC: E01F9/619
Filed: 1973-05-24
Abstract: 1416747 Road signs M AMANN 24 May 1973 [25 May 1972] 24883/73 Heading E1G [Also in Divisions G1 and G5] A sign includes a transparent element e.g. 34 or 134 movable between a light reflective or light emitting member 52 or 152 and an opening 20, 22 in a housing 12, and measuring means which detects the degree of dirt accumulation on the transparent element and, when it exceeds a set limit, actuates a drive means to move the element to replace the dirty section with a clean section. At set intervals, the drive moves either the transparent element or a separate test element on a small amount to a photoelectric measuring device consisting of a light emitting diode and photosensitive resistance 46 which comprises the measuring means. If the element is clean, the drive is switched off but, if it is dirty, the element is driven on sufficiently to replace the dirty section with a clean one. The said intervals may be dependent upon the ambient temperature. The drive may be controlled by a photometer so as to operate only after dark. The element may be a continuous belt passing through a cleansing bath 160 and past brushes 164-168 or may be a rigid, rotatable cylinder coated with P.T.F.E.

Patent GB-728522-A (GB)
Title: Improvements in the production of pure adiponitrile
Filed: 1952-10-08
Abstract: Pure adiponitrile is obtained from crude adiponitrile containing 1-cyano-cyclopentanone-(2) and/or its imide by treating the crude adiponitrile, preferably at elevated temperature, with hydrocyanic acid, and distilling off the pure adiponitrile from the higher-boiling reaction products of the hydrocyanic acid with said impurities.  When the crude adiponitrile is obtained by reacting 1.4-dichlorobutane and excess sodium cyanide the amount of hydrocyanic acid necessary for reaction with the said impurities may be obtained by adding to the reaction mixture, before distilling off the adiponitrile formed, a small amount of an aqueous solution of hydrochloric, sulphuric or phosphoric acid or of an alkyl or aryl sulphonic acid at temperatures of from about 40 DEG  to 100 DEG  C. When the crude adiponitrile is obtained by catalytically reacting adipic acid with excess ammonia the hydrocyanic acid may be introduced into the vapours leaving the catalyst but instead of ready-made hydrocyanic acid there may be employed corresponding amounts of formamide or methyl formate which are added to the reaction mixture at a temperature above 160 DEG  C. at which temperature the formamide splits up into hydrocyanic acid and water and the methyl formate reacts with the excess ammonia to form hydrocyanic acid, water and methanol.  In examples (1) a mixture of pure adiponitrile and 1-cyanocyclopentanone-imide (2) and/or the corresponding ketone is heated to 60-80 DEG  C. and hydrocyanic led in.  The mixture is allowed to stand at 60-100 DEG  C. and then distilled in vacuo; (2) sodium cyanide is added to pure adiponitrile and reacted with 1.4-dichlorobutane at 180-190 DEG  C.  A small amount of sulphuric acid which may either be concentrated or diluted to 50 per cent with water, is then added and after stirring for 1 to 2 hours the mixture is distilled to yield an additional amount of pure adiponitrile; (3) ammonia is led through molten adipic acid at 330-350 DEG  C. and the resulting adiponitrile, after the addition of formamide, is led at about 200 DEG  to 300 DEG  C. over a short layer of pieces of chamotte containing phosphoric acid, the vapours leaving the chamber being condensed to recover adiponitrile containing less than 0.1 per cent of 1-cyano-cyclopentanone-(2)-imide.

Abstract: 1,131,546. Production and separation of radio-isotopes. UNION CARBIDE CORP. 8 June, 1966, No. 25433/66. Headings G6P and G6R. Radioactive molybdenum 99 is prepared by neutron irradiation of MoO 3 , other molybdenum oxides, or molybdic acid. The molybdenum compound is then dissolved in a base and the solution is adjusted to an acid pH, but above 2À5, and contacted with an inorganic anion exchange material which retains the molybdenum. In an example, irradiated MoO 3  is dissolved in NH 4 OH, and the solution is acidified to pH 3À0-3À5 with nitric acid and then passed through a column of alumina. Short-lived radioactive technetrum 99m, useful in medical research and diagnosis, is prepared by elution of the ion exchange material with hydrochloric acid. Other suitable anion exchange materials are ZrO 2 , ThO 2 , WO 3  and SiO 2 .

A refrigeration system comprises a first circuit having a condenser 4, receiver 8, expansion valve 10 and evaporator 11; and a second circuit having a heat exchanger 17 in thermal contact with receiver 8, a condenser 18, a separator 19, a receiver 20, expansion valve 21 and an evaporator 22, the two circuits having a common compressor 2. Air is passed by a fan 34 successively over evaporator 11 and condenser 18 into a space to be conditioned and the compressor is driven by a continuously running I.C. engine 25. Valves V1 and V2 in the first circuit and valve V3 in the second circuit are controlled by a thermostat 35 in such a manner that: (i) when the space requires to be cooled, valves V1 and V2 are open and valve V3 closed so that only evaporator 11 is operative; (ii) when the space requires to be heated, valves V1 and V2 are closed and valve V3 open, the air is heated by condenser 18 and the heat supplied to receiver 8 by exchanger vaporizes some of the refrigerant therein, the refrigerant vapour returning to the compressor for circulation through the second circuit, and (iii) when the space requires neither heating or cooling, valves V1, V2 and V3 are all open, so that evaporator 11 and condenser 18 are both operative and there is substantially no net heating or cooling effect. During the heating cycle, the evaporator 22 of the second circuit receives heat from a heat exchanger 27 in the coolant circuit for the engine 25; if the coolant temperature is initially too low a valve 24 opens a by-pass line 23 for supplying high pressure vapour from separator 19 to the evaporator 22 until a sufficient high coolant temperature is reached. The coolant circuit further includes an aircooled radiator 28 having a thermostatically controlled by-pass 29.

Filed: 1963-06-28
Abstract: <PICT:1044963/C6-C7/1> <PICT:1044963/C6-C7/2> Iron moulds, e.g. for moulding glass or possibly rubber or plastic articles, are electrolytically cleaned using an aqueous solution of sodium hydroxide and sodium gluconate having a water: sodium hydroxide sodium gluconate ratio range by weight of 6.3 to 10.8:2:1, the concentration of iron in the electrolyte being maintained below 0.1 g/l by continuously plating out iron from the electrolyte in a separate cell.  Typically iron moulds are first cathodically degreased in an alkaline solution, rinsed by immersion in cold water or with steam or hot water sprays, and then cathodically cleaned in an aqueous solution containing per gallon 32 ozs NaOH and 16 ozs sodium gluconate at a temperature of 180 to 190 DEG F at a current density of 100 A.S.F. using a periodic reverse current cycle of 15 secs. as cathode and 3 secs. as anode. The moulds are loaded into carriers which are moved into the successive baths by a continuously moving conveyer which is arranged to raise and lower the carriers as required.  The carriers 12 may include suspension arms 11 and annular metal plates 17 (Fig. 2) connected to current leads 18 on which pairs of semi-cylindrical half-moulds 20 are stood upright so that their interiors surround carbon electrodes 21 or the half moulds 27 are placed interiors upwards on a conductive plate 16 connected to current leads 26 while a carbon plate 28 is suspended over them by carbon posts 29. The cleaning electrolyte is pumped continously from the bottom of the cleaning tank to the bottom of the iron plating-out tank in which the cathode comprises a hollow vertical cylinder of expanded metal-iron or steel-surrounding a pair of carbon anodes, the liquid in the plating-out tank returning by gravity to the cleaning tank via an overflow conduit.  With a tank capacity of 55 U.S.A. gallons and a flowrate of 3 to 5 U.S. gallons/minute, a current of 500 amps keeps the iron content in the range 0.04 to 0.08 g/l.
