Title: Improved process for increasing the bulk density of powdered substances
IPC: B01J2/00
Filed: 1948-02-26
Abstract: The bulk density of a powdered substance, such as a soapless detergent powder or a soap powder, which can be increased by the addition of moisture, is increased by mixing the powder with a finely-divided salt containing water of crystallization and subsequently causing the salt to give up some or all of its water of crystallization.  The required amount of water of crystallization may be evolved by heating the mixture to a suitable point; about 40 DEG C. is exemplified.  This may be effected continuously, such as by passing the mixture down a heated rotating tube.  Efflorescent salts are preferred; sodium sulphate, sodium carbonate and sodium phosphate are specified.  Copper sulphate and magnesium sulphate are less desirable as high temperatures are necessary to release the water of crystallization.  Likewise, magnesium chloride and calcium chloride are undesirable since they are deliquescent.  The invention is particularly applied to soapless detergents produced in the powder form such as the sodium salts of sulphated fatty alcohols.  The substance known under the Registered Trade Mark " Teepol XL " is specified.

Title: Improved method of treating materials with high energy particles
Inventor: BIRKS JOHN BETTELEY
IPC: G21K1/093
Filed: 1955-02-28
Abstract: An elongated body, such as an electric cable, which is being moved continuously lengthwise transversely through a stream of particles, e.g. electrons, is irradiated on both sides in a single passage by allowing the first part of the beam to impinge directly on one side of the body and the second part to pass the body and to enter a substantially uniform and constant magnetic field transverse to the general direction of the beam and of such strength that the beam is deflected through approximately 180 degrees and impinges on the opposite side of the body.  A source of electrons such as a Van de Graaff <PICT:0789456/III/1> accelerator 6, with an energy output of 0.5 Mev. or higher, and preferably a beam output of 250 Mev. and a beam of 0.6 centimetres diameter, has a vertical accelerator tube 7 provided with scanning coils arranged in enclosure 8 to emit a beam of electrons 9 through a thin aluminium window.  The beam operates transversely to the axis of a cable 10 over a distance of 3.2 centimetres and the cable passes above the poles 13 and 14 of the electromagnet 15 which have an end face four centimetres square and adjusted to provide a gap of one centimetre, the plane bisecting the gap being the plane bisecting the beam and the plane in which the beam is oscillated.  The field strength necessary to deflect the electron beams through a circle of diameter equal to that of the cable is of the order of 8,400 Oersteds.  Preferably since oxidation is liable in air, the atmosphere around the irradiated material is an inert gas.

IPC: H03K23/82
Filed: 1958-02-26
Abstract: 822,691. Electronic counting-apparatus. STANDARD TELEPHONES & CABLES Ltd. Feb. 26, 1958, No. 6169/58. Class 106 (1). [Also in Group XL (c)] In a multi-stable state counting-chain comprising a number n of individual static switches one is in the non-operated condition and the other n - 1 in the operated condition, each pulse to be counted applied from a common supply lead moves the non-operated condition one stage along the counting chain. Fig. 1 shows a counting-chain comprising cold cathode gas discharge tubes V1, V2 ... Vn in which when a positive pulse is applied at lead S all the tubes except tube V1 are set to the conductive state. The negative-going pulses to be counted are applied to common lead IPL to gates comprising diode rectifiers MR1, MR2, such that only the diodes conduct which are associated with the non-conducting stage, for example V1. Thus an applied pulse via diode MR1 lowers the cathode potential of tube V1 to cause it to conduct and simultaneously via diode MR2 lowers the anode potential of tube V2 to cut it off. Thus each input pulse advances the non-conductive state one stage along the chain. Output pulses may be taken for example from the anode and cathode of each stage. In a modification shown in Fig. 2 the cold cathode tubes V1, V2, &c. are replaced by semi-conductor junction diodes JD1, JD2, JD3, the initial setting of the circuit being determined by the application of a negative pulse to their lower ends.

Filed: 1958-02-27
Abstract: 885,157. Coating with metals. UNION CARBIDE CORPORATION. Feb. 27, 1958, No. 6323/58. Class 82(2). Particles of alkaline-earth metal are coated with a protective metal by contacting them with a heat-decomposable metal-bearing gas while they are suspended in a flowing stream of a gas inert to the particles and at a temperature at which said metal-bearing gas decomposes. Specifically, calcium, barium, magnesium- or strontium particles may be coated with nickel, chromium or iron by carbonyl decomposition using carbon dioxide, argon or neon both to suspend the particles and to act as a carrier gas for the metal-bearing compound. As shown, alkaline-earth metal particles 24 flow into conduit 19 and are carried into duct 15 by a stream of inert gas (from source 31) where they are pre-heated by induction coil 39 and then into duct 13 where they are contracted by metal bearing compound which is carried into the duct through conduit 45 by carrier gas from source 55 flowing through container 49 over liquid metal-bearing compound. Decomposition of the compound takes place in heated duct 11 and the resulting coated particles are collected in chest 1. Pure alkaline-earth metal may be reclaimed from the coated particles by heating them to above the melting-point of the alkaline-earth metal and removing the resulting supernatant liquid layer of alkaline-earth metal from the solid coating metal.

Title: Improvements in and relating to titanium dioxide pigments
Inventor: DURRANT GEORGE GEOFFREY
IPC: C09C1/00
Filed: 1962-02-19
Abstract: A rutile form titanium dioxide contains from 0.04% to 5.0% of molybdenum trioxide and from 0.02% to 0.8% of aluminium oxide, the ratio of the quantity of molybdenum trioxide to the quantity of aluminium oxide on a weight basis being at least 2: 1, the balance being titanium dioxide and the percentages being by weight of the total.  The above ratio is preferably within the range 3: 1 to 8: 1 but certainly does not exceed 50: 1.  Various pigment compositions are claimed, and the mean particle size of this pigment is within the range of from 0.5 to 2.0 microns.  The above pigment composition may be modified by incorporating therein a quantity, preferably within 0.1 to 1% by weight, of a texture modifier that consists of an alkali metal salt or mixture of such salts, e.g. Na2SO4 and K2SO4, or instead of said modifier, or in addition to it, a quantity of sodium fluoride and/or potassium fluoride may be added to improve the brightness of the pigment, the quantity of said fluoride being within the range of 0.5 to 5% based on the weight of the calcined pigment. The above pigments may be prepared by calcining under reducing conditions at a temperature in the range 900 DEG C. to 1350 DEG C. a mixture containing TiO2, Al2O3 and MoO3 together with texture modifiers and/or brightening agents if required. The aluminium and molybdenum oxide may, if desired, be replaced, at least in part, by an aluminium compound, e.g. the sulphate or nitrate, or a molybdenum compound, e.g. molybdic acid or ammonium molybdate, which compounds decompose to give the corresponding oxide on heating.  The process may also be carried out under oxidizing conditions.
