Abstract: 878,514. Colour photography. KODAK Ltd. Oct. 14, 1957 [Oct. 12, 1956], No. 31955/57. Class 98(2) In a multilayer silver halide colour former material preferably of the kind having the blue sensitive layer next to the support at least one layer, or an intermediate silver halide emulsion layer, contains an emulsion of the internal latent image type as described in Specifications 581,772, 581,773 and 635,841, to the silver halide grains of which is adsorbed a non-image forming colouring material. The colouring material so adsorbed prevent light-scattering, either of light passing to lower layers or reflected therefrom to upper layers and are stated also to assist in preventing deleterious effects caused by wandering of optical sensitizing dyes from grain to grain or from emulsion to emulsion. The colouring materials are disclosed as readily soluble cyanine dyes only. The preferred material with blue sensitive layer lowermost may have this layer of much higher blue light speed than the green and red sensitive layers, or the entire material may be exposed through a yellow filter which absorbs all blue light to which the upper layers are sensitive but not all to which the lowermost layer is sensitive. Example 1 describes preparation of an internal latent image emulsion containing 3 :3<SP>1</SP>- dimethyl-9-phenyl-4:5:4:5<SP>1</SP>-dibenzothiacarbocyanine bromide as red light absorbing material, addition of this to a specified red-sensitive cyan coupler chlorobromide emulsion and coating of the mixture on to a support provided with a blue-sensitive yellow coupler layer, which coating is followed by a green sensitive magenta coupler layer with, optionally, an internal latent emulsion having adsorbed thereto a green light absorbing dye; and exposure and processing of this are described briefly. Examples 2, 3 are directed to the production of cyan coupler internal latent image emulsions containing other cyanines and 4, 5 to corresponding magenta coupler internal latent image emulsions, all for use in the manner of Example 1. Specification 541,589 also is referred to.

Title: Narrow band discriminator circuit
IPC: H04J1/08
Filed: 1955-11-11
Abstract: 787,605. Frequency discriminators. STANDARD TELEPHONES & CABLES, Ltd. Nov. 11, 1955 [Nov. 12, 1954], No. 32284/55. Class 40 (5). A narrow bandwidth frequency discriminator of Ferris type comprises two equally and broadly tuned circuits 8<SP>1</SP>, 91 and 101, 11<SP>1</SP> coupled by a circuit, e.g. a piezo electric crystal 28, series resonant at the same frequency so that the rectified and smoothed outputs of each circuit are respectively a twin peak flat trough response curve 36 (Fig. 8) and a response 35 having a flat top between the peaks of the primary response curve 36. The difference between the primary output voltage 36 (or a fraction of it taken from a potentiometer 14<SP>1</SP>) and the secondary output voltage (across resistor 15<SP>1</SP>) is then a flat response output which reverses in polarity for frequencies on either side of f0 lying within the narrow band f1-f2. The discriminator is therefore useful for rejecting adjacent channel pulses in a frequency multiplex pulse radio system. An inductance 29 may shunt the crystal 28 to resonate with the crystal shunt capacity at the centre frequency f0, so that the impedance of the crystal and inductance 29 at adjacent frequencies f1, f2 is nearly infinite and the secondary circuit output then zero. In a modification the discriminator comprises a T formed of three inductances with a piezoelectric crystal shunted across all the series inductance and capacitors, oppositely-poled rectifiers and smoothing circuits shunting the input and output of the T, both the smoothed outputs being connected by a resistor from a centre tap of which the output is taken.

Title: Process for de-inking printed paper
IPC: D21C5/02
Filed: 1961-09-08
Abstract: Printed paper is de-inked by pulping it in an aqueous solution of a non-ionic detergent which is an alkyl phenol-ethylene oxide adduct in an amount of 1-2.5% by weight of the dry paper, the carbonate hardness of the water being below 15 p.p.m. and the temperature of the solution being between room temperature and the cloud point of the non-ionic detergent.  The hardness of the water used to prepare the solution may be reduced by treating it with a zeolite or by adding thereto a softening agent, e.g. trisodium phosphate, tetrasodium pyrophosphate, sodium hexametaphosphate or mixtures thereof, in an amount of from 0.1 to 4% by weight of the dry paper. The non-ionic detergent may be a compound having the formula R-O-C2H4-(-OC2H4-)n OH in which R is an alkyl phenyl radical having 9-19 carbon atoms in the alkyl chain and n is an integer of 4-30. Below 10% by weight of the solution of the dry printed paper which may be shredded is preferably added to the solution and pulping may be continued at 1\sv10 DEG -140 DEG F. for 10-50 minutes.  The pulp may then be diluted with water to a solid content of 0.5-1.5% based on the weight of the solution, separated from the solution, washed, thickened, acidified to a pH of 4-6.5 with, for example, sulphuric acid or SO2, if necessary bleached, and then thickened and formed into a web.  The recovered pulp may be blended with fresh sulphate or sulphite stock.  Specification 991,117 is referred to.

Title: Spinners for angling
IPC: A01K85/12
Filed: 1954-11-10
Abstract: 781,779. Fishing lures. RIGHYNI, R. V. Nov. 7, 1955 [Nov. 10, 1954], No. 32474/54. Class 48. An angler's spinner comprises a body furnished with a cam-shaped open slot 6 housing a hook 7 in a concealed position and a chamber 4 containing means to which the hook is secured and which withdraws the hook from the body when the angler strikes, the cam-slot 6 acting to project the hook outwardly. The spinner shown has two cam slots 6 for two hooks. The slots extend through the length of the body and are contoured at their rear ends to house snugly the outwardly facing hooks. The hooks are coupled by flexible wire 8 to a washer 10 slidably mounted on a pin 11 and pressed upwardly by an adjustable lighthelical spring 18 to abut a frame 15 detachably held in the chamber 4 by a pair of pivoted dogs 16, Fig. 2, engaged with recesses 5 in the chamber. The upper end of the pin 11 is fixed to a member 14 of rectangular cross-section adapted to slide in the frame 15 and to cooperate with the free ends of the dogs 16 to hold the dogs in the recesses. The line is attached to the upper end of the pin 11 and when the angler strikes the pin moves upwardly so that the rectangular member 14 clears the ends of the dogs 16 and the spring 18 is compressed until a sleeve 19 surrounding the lower end of the spring engages the washer 10. Further upward movement of the pin causes the dogs to pivot out of the recesses 16 and the frame to move out of the chamber 4. Simultaneously, the hooks move upwardly and outwardly relative to the body. The ends 21 of vanes 20 mounted on the body overlap the upper ends of the slots 6 to engage the hooks and prevent the body from becoming detached from the hook assembly. The Provisional Specification describes a spinner having two hooks disposed in camshaped slots in the body and connected both by wire loops and by weak twine to a nose detachably secured to the body. When the angler strikes the twine breaks and the hooks move forwardly and outwardly. The body has a chamber for housing weights, which may be detachably secured to the nose.

Abstract: 1,244,753. Non woven fabric, testing textiles. E. I. DU PONT DE NEMOURS & CO. 8 July, 1968 [7 July, 1967 (3)], No. 32524/68. Headings D1F, D1N and D1R. [Also in Division F2] A non-woven web is made by forming a plurality of primary gas streams each forwarding a plurality of electrostatically charged continuous filaments 1, collecting the separated filaments on a continuously moving surface 3 and pneumatically oscillating at least one of the gas streams so that its filaments traverse the moving surface 3 at a substantially constant deflection amplitude and at a substantially consant deflection velocity which is at least one third of the velocity of the filaments along their length as measured immediately before oscillation. The oscillation can be effected by impinging on the primary gas stream at least one secondary gas stream, e.g. via slots 5, 6, at an angle of 60-90 thereto to deflect the filaments by up to 45. A plurality of parallel streams of filaments, as shown, can be deposited on a foraminous surface subjected to suction so that they touch each other either at the points of reversal or at adjacent edges. The gas supply to the secondary stream jets can be via a single source and a rotary valve providing a gas flow at sonic velocity through the outlet and a less sonic velocity in the conduits to the gas jets 5, 6. The secondary stream jets may produce 6-100 pulses/sec. The filaments can be segmentally drawn isotactic polypropylene. The webs formed can be bonded with saturated stream, lubricated with a polysiloxane containing surface active agent and tufted. The web produced may have the properties described in Specification 1244754. Determination of filament orientation in the web produced can be achieved by directing a beam of parallel light rays on the web at an incidence angle of less than 90. The light reflected in a plane perpendicular to the filament axis (which will come from only those filaments in the plane of the web having an axial orientation perpendicular to the incedent rays) collected, magnified and focussed onto a photomultiplier tube to be electrically estimated. An estimation for varying directions of incedent light rays is performed to measure the proportions of filaments in the varying directions in the web. See Fig. 6 (not shown).
