Title: Process for the manufacture of white pigments
IPC: D06L4/657
Filed: 1964-07-09
Abstract: A pigment composition is prepared by making an aqueous mixture of a colourless, water-soluble melamine-formaldehyde condensate, an inorganic white pigment derived from Be, Mg, Ca, Sr, Ba, Zn, Cd, Hg, Al, Ga, In or Tl, and an optical brightener which is a stilbene derivative containing at least one acid group giving water solubility, then curing the condensate, and comminuting the resultant mass. The melamine-formaldehyde resin preferably derives from 2-3 mols. formaldehyde per mol. of melamine, and the white pigment may be, e.g. MgO, ZnO, CaSO4, SrSO4, Al2O3, particularly a lithopone, CaCO3, BaSO4 or ZnS.  The optical brightener is preferably a triazinylaminostilbene, particularly a compound of the formula <FORM:1032057/C3/1> wherein X is a carboxylic or sulphonic acid group, and T1 and T4 are s-triazin-2-yl residues. Examples of this type are listed.  There are preferably used 0.5-5 p.b.w. of brightener and 50-200 p.b.w. of resin per 100 parts by weight of pigment. The composition is usually cured by heating to 50-200 DEG C. so that the water escapes, and the resulting mass is ground to a fine powder.  In examples, pigments are prepared from 100 p.b.w. melamine-formaldehyde resin in 100 p.b.w. water, with 0.7 to 3.5 p.b.w. of various optical brighteners and 100 p.b.w. of lithopone, barium sulphate, calcium carbonate, or zinc sulphide.  A white polyethylene may be obtained by incorporating into the polyethylene 2-5 parts by weight per 100 of a pigment of the invention.

Title: Noise suppressor circuit
IPC: H03K3/013
Filed: 1974-06-27
Abstract: 1473706 Pulse width discriminating circuits STANDARD TELEPHONES & CABLES Ltd 27 June 1974 28512/74 Heading H3T A noise suppression circuit comprises: a first MOS two-input AND gate 9 to the inputs of which a sampling input signal IP2 and a further input signal IP1 to be compared are applied; a first bi-stable 3, 4 having one input connected to the output of gate 9 and its outputs connected to respective first inputs of further two-input AND gates 7, 8; a second bistable 5, 6 having its inputs connected respectively to the outputs of gates 7, 8; and the input signal IP2 being also applied to a second input of gates 7, 9. A first sample pulse prepares gate 9 so that a "1" level input signal will pass through it to set bi-stable 3, 4 preparing gate 8. If the input "1" level persists sufficiently long for a second sample pulse to arrive, this pulse will pass through gate 8 to set bi-stable 5, 6 and produce an output. If the input "1" level ceases before the next sampling pulse the resulting "0" level is inverted by NOR gate 2 to reset bistable 3, 4. When the bi-stables are both set, the circuit will similarly distinguish between long and short "0" conditions of the input signal, that is bi-stable 5, 6 will only reset if a "0" level condition is sufficiently long to span at least two sampling pulses.

Title: Improvements in or relating to television cameras
IPC: H01J29/02
Filed: 1958-09-05
Abstract: 832,157. Television. FERNSEH G.m.b.H. Sept. 5, 1958 [Sept. 7, 1957], No. 28573/58. Class 40 (3). [Also in Group XL (c)] The electron image in a television imageorthicon camera tube is subjected to a periodic deflection at a frequency low in relation to the frame deflection frequency by means of auxiliary coils 6 and 7 adjacent the photo-cathode 3 to which 90 degree phasedisplaced currents are applied from ganged motor-driven potentiometers 8, 9, whilst a corresponding deflection is imparted to the scanning raster by also applying the currents to the main deflection coils 4, 5. The invention prevents the production of spurious signals due to the stationary bright scenes becoming " burnt " into the camera storage electrode 2. Capacitors 12 and 13 prevent the main scanning currents from flowing through coils 6 and 7. Appropriate impedances may replace capacitors 12 and 13 for the purpose of passing currents into coils 5 and 6 to compensate for deflection of the electron image due to fringing fields from the main deflection coils. Voltages may be taken from the auxiliary deflection circuit for introduction into the video signal circuit to compensate spurious signals. The periodic deflection may be circular, or perpendicular to the line-scanning direction.
