Filed: 1974-04-10
Abstract: 1458722 Foamed cured silicone gums XEROX CORP 10 April 1974 [13 April 1973] 15894/74 Heading C3C [Also in Divisions B2 and B6] A lithographic printing plate is prepared by depositing particles on a layer of an uncured silicone gum containing a blowing agent, blowing and curing the silicone layer, and removing at least some of the particulate material. The particulate material resists escape of the blowing gas so that the plate has a porous ink-receptive structure in those areas covered by particulate material. The particulate material may be applied image-wise, e.g. as a toner image produced electrophotographically, or uniformly. Particulate material may be removed, after blowing, by evaporation, abrasion or dissolution. The silicone may be room temperature vulcanizable or heat-cured. The blowing agent may be activated by heat or by radiation, e.g. U.V. light. In the examples silicone gums containing ethylene carbonate or 2,2<SP>1</SP>-azo-bis(2- methylpropionitrile) were coated on to aluminium sheets, the coatings were contacted with developed images made of toner particles, heated and washed with acetone to remove all the toner particles and leave foamed areas corresponding to the toner patterns.

Title: Preparation of titanium dioxide
Inventor: EVANS ARTHUR WALLACE
IPC: C01G23/07
Filed: 1959-05-08
Abstract: In the production of titanium dioxide by vapour phase oxidation of the tetrahalide in a fluidized bed, deposition of TiO2 on the bed particles is reduced by introducing metallic aluminium into the bed, for example as discrete particles, dropped into the bed, as wire or in molten form. Thus fine aluminium particles can be entrained and fed in a chlorine, carbon dioxide, nitrogen or argon stream or colloidal, fume aluminium may be fed mixed with the oxygen stream. The bed material may be withdrawn, cleaned and recycled, as in Specification 919,019, in which case aluminium may be added to the recycled solids.  The amount of aluminium may be from 0.1 to 10% or higher. Specification 761,770 also is referred to.

Title: Improvements in electrical apparatus for amplifying small d.c. voltages or currents
IPC: H03F9/02
Filed: 1946-05-27
Abstract: 629,287. Magnetic amplifiers. ELLIOTT BROS. (LONDON), Ltd., and PIZZEY, C. F. May 27, 1946, No. 16060. [Class 40 (iv)] [Also in Group XL (c)] The input to a D.C. amplifier is applied to vary the saturation of a reactor and thus the A.C. input to an amplifier the output of which is rectified, and negative feed-back is provided from the rectified output to the input. As shown, the D.C. input is applied to the polarising windings 4, 4a of a saturable reactor 6, and an output at twice the supply frequency is fed to an amplifier valve 11 with a tuned anode load 13, 14 feeding an amplifier 12. The output of valve 12 is fed to a phase discriminating network 20, a reference frequency being supplied from frequency doubler network 30. The output of the phase discriminator is applied to two opposed rectifiers 23, 24 in parallel, and the output of rectifier 24 is fed to the grid of valve 26, which is connected across the supply voltage in series with a condenser 31. The anode of valve 26 is connected to the cathode of a gas-filled relay valve 32 whose grid is connected to the cathode of valve 26. Alternating voltage at the supply frequency is applied across relay valve 32, feed-back resistance 3, delay switch 33 and the output circuit. The phase control valve 26 is biassed nearly to cut off. A D.C. input of correct polarity produces an output from the phase discriminator 20 in a sense to alter the phase of the voltage applied to the grid of the relay valve 32 so as to give a D.C. output. The saturable reactor may be replaced by an impedance bridge using resistances and biassed reactors, Fig. 2 (not shown), or by an impedance bridge of the type described in Specification 597,410, [Group XXXV]. The output from the magnetic invertor may be fed to the amplifier across a rejector circuit tuned to unwanted frequencies.

[Class 110 (ii).] A reversible gear-wheel pump with one-way delivery is contained in a framework which has limited angular travel between two stops and which is moved frictionally by the rotation of the driving gear wheel about its shaft centre. Two gear wheels 7 on a driving shaft 4 mesh with two gears 11 on a spindle 10 which is supported at its ends in two side-plates 9 and at its centre in a bearing contained in a partition wall 8. The wall 8 and the side-plates 9 which are bolted together are clear of the shaft 4 and move against one or other of the stops 20 dependent upon the direction of rotation of the gear 7, the wall 8 having a curved extension piece 15 which slides on the curved inner wall of the pump casing. Fluid to be pumped enters the pump by way of ports 16, 17 and is delivered through ports 19, 18. A portion of the delivery fluid is tapped off to supply the shaft bearings with lubricant and also fed to the sides of plates 9 for axial balancing purposes. A handlever may be fitted outside the pump casing and connected to the rockable framework by a pin-andslot device so that the framework can be tested for freedom of movement, or a pointer affixed to indicate the position of the framework. The pump may have one or more than two stages working in parallel on the same shaft.
