Patent GB-582808-A (GB)
Title: Improvement in abrasive compositions and method of forming same
IPC: C09K3/14
Filed: 1944-05-09
Abstract: An abrasive composition for making grinding tools particularly for grinding lenses consists of small diamond particles dispersed in a matrix of iron-carbon alloy containing .45-1 per cent. carbon, the diamonds being secured in the matrix by a thin surface coating of a platinum-group metal mechanically adherent to the diamonds and alloy-bonded to the iron.  The diamond particles, ground to pass 100 mesh but to be retained by 120 mesh, and cleaned from surface dirt and grease, are provided with the surface coating of a platinum-group metal, preferably rhodium, by electronic deposition as described in U.S. Specification 2,103,623, (see Group XL).  They are then mixed with finely-divided iron-carbon alloy containing preferably approximately .87 per cent. carbon, packed in an annular mould at a pressure of 10-20 lbs. per square inch, and heated, under non-oxidizing conditions and in the absence of hydrogen and nitrogen, to a temperature above the eutectoid temperature of 725 DEG C. but below 800 DEG C. for a period of about 3 hours to convert the alloy to austenite.  The mass is then quenched and subsequently heated to 300-700 DEG C. to obtain the desired hardness. Preferably, the alloy used is prepared from iron obtained as spheroidal particles passing 400 mesh by the decomposition of iron carbonyl, and sufficient finely-divided sugar carbon is added to ensure substantially complete removal of any occluded or combined oxygen.

Title: Improvements in or relating to dispersions of inorganic metal compounds in lubricating oil and methods of making the same
Inventor: CARLYLE ROBERT LEWIS
IPC: C10M159/20
Filed: 1955-03-25
Abstract: Stable dispersions of metal compounds in lubricating oil are prepared by forming a homogeneous mass of a lubricating oil, an oil-soluble surface-active agent, an oil-insoluble compound of an alkali metal (lithium, sodium, potassium, caesium or rubidium) or an alkaline earth metal (barium, magnesium, calcium or strontium), water in a proportion not less than 2.5 per cent by weight based on the amount of surface-active agent present, and an aliphatic alcohol containing less than 6 carbon atoms per molecule, precipitating from the mass an oil-insoluble inorganic compound of the metal in the form of a dispersion of particles the diameters of which are less than 1 micron, and removing the residual alcohol and water.  The lubricating oil may be a hydrocarbon oil such as mineral oil or may consist wholly or in part of fatty oils such as corn oil, soybean oil or lard oil.  Blended lubricating oils may contain voltalized oils or synthetic oils of lubricating viscosity.  Suitable anionic surface-active agents are sulphonates, phenolic compounds, organic phosphorus compounds, phosphorus sulphide-treated olefins and metal soaps of carboxylic acids and many such compounds are specified. Suitable cationic and non-ionic surface-active agents are also listed. Oil-insoluble metal compounds which may be employed include oxides, hydroxides or alcoholates, but peroxides, carbonates, thiocarbonates, hydrides, nitrites, sulphides, borates, perborates, fluoborates, arsenites, fluosilicates, hypophosphites, formates, acetates, lactates, citrates, phenolates, benzoates, salicylates, a cetylsalicylates and naphtholates are also mentioned.  The precipitation may be effected by evaporation of the alcohol or by chemical means, for example by passing carbon dioxide or hydrogen sulphide through the mass.  The alcohol may be used in conjunction with another solvent, such as a hydrocarbon (particularly benzene, toluene or naphtha) or a higher alcohol (e.g. capryl alcohol, tridecyl alcohol or hexanol).  The final dispersion may be blended with further lubricating oil to produce a lubricating composition, to which additional substances, such as anti-foaming agents, pour-point depressants and oiliness improvers, may be added. Numerous examples of the preparation of dispersions are given.

Title: Improved apparatus for the recovery of heat from the effluent of wet processing machines
Inventor: FREEMAN SAMUEL RICHARD THOMPSO
IPC: D06B23/22
Filed: 1960-03-14
Abstract: 921,564. Heat exchangers. FREEMAN, TAYLOR MACHINES Ltd. March 14, 1961 [March 14, 1960], No. 8912/60. Class 64 (3). Heat from waste liquor discharged from a group of dyeing or like wet treatment machines 1 to a common outflow line 4 and thence to a sump 5, is recovered in a heat exchanger 7, 7a which gives up this heat to fresh cold liquid being fed either directly, or indirectly e.g. by way of a storage tank 9, to the machines, the inflow and outflow to and from the respective machines being controlled by manually or automatically actuated valves such that hot waste liquor from one or some of the machines 1 may be discharged through the heat exchanger to heat up fresh liquid being supplied to another of the machines. In the system shown, when the drain valve 22 of any one or more of the machines is opened, hot waste liquor flows to the sump 5 and ultimately reaches the level of short probes 19 which switch on firstly the waste pump 6 and then the clean fluid inlet pump 10. Clean fluid after being heated in the heat exchanger 7, 7a flows through conduit 11 and then to the machines 1. As the machines become fully charged with clean liquor 2 the supply of hot waste liquor from the machines consequently diminishes, and the sump level drops until it reaches the low-level determined by probes 20 which then switch off the pumps. If during the recharging operation it should happen that the inlet valves 13 of all the machines are closed the pressure of the heated clean liquid leaving the heat exchanger will open a relief valve 14 allowing the liquid to flow into the storage tank 9. Subsequent opening of the inlet valve on any of the machines will then allow a flow of liquid from the storage tank to the machine by way of non-return valve 15. The heat exchanger may comprise a shell and tube type unit (Figs. 3 to 5, not shown) or a plurality of such units interconnected in series or in parallel. The heat exchanger may, in a modification (Fig. 2, not shown), be built into the tank 9.

Abstract: 550,337. Rotary-table moulding machines. PARFITT, A. W. (Lauterbach Corporation). July 24, 1941, No. 9384. [Class 87 (ii)] In a rotary-table moulding machine comprising an annular series of cylindrical moulds 32 arranged in spaced relationship and adapted for successive contact with a movable cam member 62 which actuates a mould charging mechanism, blocks 80 are disposed between selected moulds in order to render the cam member inoperative during a part of the rotary movement of the machine, as for the purpose of employing only half the moulds or for employing only one mould for experimental purposes. Thus, the cam 62, which normally sinks into the intermould spaces filled by the blocks, rides over the surface of the blocks. Each block is secured in position by two curved members 84 which fit between the moulds and have screwed shanks 86 passing through holes in the block and receiving nuts 87. The invention is described in connection with the machine described in Specification 527,984, in which the cam 62 oscillates a charging arm 50 bearing a charging element (not shown) which conveys moulding material from a chute to a mould. Each block 80 prevents filling of a mould three mould spaces away therefrom.

Title: Improvements in and relating to apparatus for determining and comparing colour content
IPC: G01J3/51
Filed: 1947-04-14
Abstract: 632,593. Photo-electric colour analysis. ENGLISH ELECTRIC CO., Ltd., HOWARD, R. J. F., and WARBURTON, E. T. April 14, 1947, No. 9882. [Class 40 (iii)] In apparatus for determining or comparing colour content, light from a source 1 is reflected from, or shone through, a sample 4 on to a photo-cell 6. Filters 8, 9 and 10 are successively introduced into the light path so that the output of the photo-cell depends on the quantity of the colour in the sample corresponding to the interposing filter. This output is then applied to an amplifier 12, and in turn to amplifiers 13, 14, and 15, the gears of which are individually adjustable. The outputs of these amplifiers are successively switched by a commutator 19 rotating with the plate carrying the filters so that each amplifies the output for a particular filter only, which is then passed to the V-plate of a cathode-ray tube. A further commutator switch increases the voltage on the X-plates in steps so that the outputs due to each filter appear in a different position on the tube. The shaft of the driving motor 11 is earthed through a slip-ring 32. In use, the sample is inserted and the gain of amplifiers 13, 14 and 15 individually adjusted so that all the traces are of the same height, the specimen then being inserted and the relative heights noted. It is stated that the cathode-ray-tube may be replaced by a number of moving iron meters. The valves used in amplifiers 13, 14 and 15 are stated to have a large negative bias so that only pulses of a certain amplitude will be transmitted. The Provisional Specification states that scales may be superimposed on the screen to enable an operator to pass or reject a sample.
