Title: Polymer Latices
IPC: A61Q5/00
Filed: 1967-03-20
Abstract: 1,153,022. Polymer latices. MONSANTO CO. 20 March, 1967 [21 March, 1966], No. 12870/67. Heading C3P. Polymer latices, suitable for opacifying products such as liquid detergents, hair creams and floor waxes, comprise the polymerization product of (a) an α,#-ethylenically unsaturated carboxylic acid, (b) an at least diolefinically unsaturated compound and (c) a vinylidene monomer, wherein the polymer particles of the latex comprise from 60-90% by weight of an inner polymer composition and 10-40% by weight of an outer polymer composition orientated to the surface of the particles, the outer polymer composition comprising from 24-70 mol. per cent of component (a), from 0À6-3À0 mol. per cent of component (b) and the balance of the outer composition being component (c). Preferably, the inner polymer composition comprises component (c) alone, or together with oomponent(a) and/or component (b). The lances can be obtained by polymerizing, in aqueous emulsion, a monomeric material capable of yielding the inner polymer composition and subsequently polymerizing a monomeric material capable of yielding the outer polymer composition. The process may be effected batchwise in two separate steps, or continuously wherein the composition of the monomer charge is suitably adjusted at appropriate stages in the process. If desired, a homogeneous product can be obtained by making the inner polymer composition the same as the outer polymer composition. In examples the inner polymer compositions comprise (i) styrene-methacrylic acid, (ii) styrene, (iii) styrene-acrylonitrile, (iv) methyl methacrylate, (v) styrene-methyl acrylate, (vi) styrene dibutyl fumarate and (vii) styrenemethacrylic acid-divinyl benzene; and the outer polymer compositions comprise (i) styrenemethacrylic acid-divinyl benzene, (ii) methyl methacrylate-methyacrylic acid-ethylene dimethacrylate, (iii) styrene-methacrylic acidethylene dimethacrylate and (iv) styreneacrylic acid-diallyl fumarate. The monomers of these compositions are polymerized in aqueous emulsion containing sodium alkylbenzene sulphonate, tetrasodium pyrophosphate and potassium persulphate, and when polymerization is completed the latex is neutralized by addition of NH 4 OH.

Title: Direction indicators
Inventor: HILL CHRISTOPHER GUY ARDERN
IPC: G01C17/24
Filed: 1967-03-22
Abstract: 1,221,295. Aircraft indicating instruments. SPERRY Ltd. and LEVY WEST LABORATORIES. 15 March, 1968 [22 March, 1967], No. 13367/67. Heading B7W. [Also in Divisions C4 and G1] A direction indicating device comprises a casing 22 containing a sphere 11 of transparent material coated on the inside with a layer 15 of a photochromic material (i.e. a material which is transparent in normal light but which becomes opaque on exposure to light of a particular frequency band), sources of light 14 of this frequency band being disposed within the casing 22 to illuminate the surface of the sphere remote from the observer, a layer 16 of filter material being applied over the photochromic layer 15 to prevent light from the sources 14 reaching the surface of the sphere nearest the observer, heading markings (not shown) marked around the periphery of the sphere 11 forming a horizon line, i.e. in the plane of Fig. 1, and a drive roller 18 for rotating the sphere 11 about a normally vertical axis 19 in accordance with a directional reference given by a gyroscopic or other compass (not shown). The heading markings and the horizon line are formed as openings in the photochromic layer 15 and in use the intensity of the light from the sources 14 causes the half of the sphere remote from the observer to become opaque. The filter layer 16 prevents this light from reaching the front surface of the sphere which remains transparent and the observer therefore looks through the nearer surface of the sphere to see the markings picked out as light patches on a dark background at the rear of the sphere 11. This allows the heading markings to be disposed in their natural sequence, i.e. east to the right of north and west to the left. Rollers 20 locate the sphere 11 and a filter 23 prevents sunlight from darkening the front surface of the sphere. Since slip may occur between the roller 18 and the sphere 11 a checking arrangement in the form of a stationary pick-off which senses magnetic markings on the sphere may be provided. Pitch and roll attitudes may also be indicated by rotation of the sphere 11 about mutually orthogonal horizontal axes, e.g. by rotation of the carrier for the roller 18 about the axis joining the rollers 20, and by rotation of the casing 22 on a shaft 21 respectively. Suitable examples of photochromic material are given in the Specification.

Abstract: 915,746. Valve non-linear circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 20, 1959 [April 23, 1958], No. 13391/59. Class 40 (b). [Also in Group XXXVI] A direct voltage varying linearly with the mean square value of an alternating voltage is derived by rectifying the resultant voltage obtained by mixing the alternating voltage with a saw-tooth voltage of constant amplitude greater than that of the alternating voltage and having a repetition period small relative to the period of the alternating voltage. The invention may be applied to analysing mechanical vibrations, e.g. of rotary engines, and to a wattmeter measuring apparent power. The sawtooth voltage is derived from an oscillator 3, Fig. 1, through known stages 4-7 and fed via capacitor 8 and resistor 10 to point P where it is added to the alternating voltage u after amplification thereof at 2, the resultant voltage being rectified at 11, 11<SP>1</SP> to produce a mean current through resistor 12 proportional to h<SP>2</SP> (1+a<SP>2</SP>/ 2 ) where h is the amplitude of the sawtooth voltage and ah that of the alternating voltage, a being less than unity. An ammeter 14 is connected across resistor 12 via smoothing elements 13, 15 and its deflection may be made directly proportional to a<SP>2</SP> by applying a voltage at 16 to compensate for the current in resistor 12, due to the sawtooth voltage, when a is zero. [(U 1 +U 2 )<SP>2</SP> and (U 1  - U 2 )<SP>2</SP> being applied in opposition through smoothing elements to a D.C. volt metor 43 and also to a recorder 50 which thus deflect linearly according to the product (U 1  x U 2 ). Analysing waveforms; mechanical vibrations, Fig. 4. The waveform to be analysed and derived, e.g. from a vibration transducer is fed to terminals 1. A reference voltage of constant amplitude is applied to terminals 31 and its frequency adjusted in steps to the fundamental and higher harmonic frequencies of the vibrations. The deflection of the meter 43 or recorder 50 at each frequency step is then a measure of the amplitude of the corresponding frequency in the waveform being analysed.]
