Title: Improvements in or relating to Particle Size Analysis
Inventor: LAUNDY BRIAN JOHN RUSSELL
IPC: G01N23/203
Filed: 1967-09-12
Abstract: 1,189,328. Particle size analysis. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Aug. 27, 1968 [Sept. 12, 1967], No. 41664/67. Heading G1A. Particle size analysis is carried out by forming a suspension of the particles to be investigated in a fluid of suitable viscosity, effecting centrifugal separation of the suspension, and during this separation process, continuously measuring the build-up of a sediment using beta particle backscattering from the sediment. The use of a centrifuge to produce sedimentation is so as to allow investigation of very small particles, of 1 down to 0À1 micron, which would be subject to Brownian movement, preventing sedimentation, if normal gravity settling of the suspension were attempted. The rate of sedimentation of individual particles is dependent on the diameter in accordance with Stoke's law, and so measurement of this rate for all particles over a time period allows a size distribution to be obtained. The Figure shows the centrifuge spindle 1 carrying an arm 2 in which is mounted a support tube 6 for a sedimentation tube containing the suspension to be investigated. The end of this tube has a beryllium window through which # -particles from a Strontum-90 source 11 mounted on stirrup 10 reach the suspension. Backscattered # -particles, passing through the window, are detected by an annular plastics scintillator 12 coupled to a photo-multiplier 14 which feeds a counting and print out device.

Title: Improvements in or relating to traffic signalling systems
IPC: G08G1/097
Filed: 1960-12-05
Abstract: 901,497. Road signals for controlling traffic; lamp failure warning devices. SIEMENS & HALSKE A.G. Dec. 5, 1960 [Dec. 10, 1959], No. 41759/60. Class 118. In a traffic light system each lamp is connected in series with a high impedance, the current flow through which actuates a supervisory relay, each lamp being lit by shortcircuiting the associated high impedance. In the system shown, the red, amber and green lamps L1, L2 and L3 are controlled by relays A, B, which are operated cyclically by the 100-point sequence switch Dr, the contacts of which are connected via the field R to selected ones of terminals r1 to r10. A choice of programmes is provided by the utilization of either the odd or even numbered terminals by actuation of PW or PW<SP>1</SP>. Assuming the former switch to be operated together with starting switch Sch, relay Z comes up when Dr reaches position 60 and connects A.C. to the circuits of the lamps. Each such circuit includes a highimpedance winding w1, w2, w3 of a transformer Du1, Du2, Du3 and the current flowing therein energizes the supervisory relays U (associated with the red and green lamps) and V (with the amber lamp) but is insufficient to light the lamps. These relays connect up the operating circuits for relays A and B, and the control paths via transformers T1, T2, T3, respectively. With A and B both down, A.C. is applied to T2 and forward biases the rectifiers KT2, KT2<SP>1</SP> which short-circuit impedance w2 so that the amber lamp L2 is lit. When Dr reaches position O relay A is operated over its winding I and locks up, thus switching off L2 and lighting the red lamp L1. At position 40, B is similarly operated and lights L2 (amber); at position 50, A is released by current flow in its winding II, thus extinguishing L1 and L2 and lighting L3 (green); and at position 90, B is released, thus extinguishing L3 and lighting L2 (amber). If a red or green lamp fails the cessation of current flow in a winding of U brings down that relay, thus releasing A and B so that the amber lamp is continuously lit. If the amber lamp fails, the resultant relapse of V switches off all the lamps. Other contacts of U and V (not shown) may be used for supervisory purposes to indicate the condition of the lamps even when the signal is not in operation..

Abstract: 1,195,249. Photo-composition process and materials. KEUFFEL & ESSER CO. Sept. 22, 1967 [Sept. 28, 1966], No.43260/67. Heading G2C. A photo-sensitive non-silver halide print-out composition and a photo-sensitive silver halide developing-out composition arranged in a common layer or in superposed separate layers on the same support or on separate supports are simultaneously exposed to a light image to obtain a visual print-out image and a coincident latent developable image. The visible image may be viewed by a safelight to which both compositions are insensitive and a succession of exposures using different images may be made on the same sensitive material to build up a composite image, e.g. in the photocomposition of engineering drawings. The latent image or images may be subsequently developed in the usual way to give an archival quality visible image, if desired with the removal or de-sensitization of the print-out composition by solvents or heating. If desired, unwanted parts of the latent image may be removed before development or only parts of the latent image may be developed. The photo-sensitive material for the process may be prepared by mixing the two photo-sensitive compositions and coating them as a single layer on a support e.g. paper, or the compositions may be coated as separate layers on the same side of a support e.g. paper or on different sides of a transparent support, or they may be in separate layers on separate supports and comprise a printout sheet material and a silver halide sheet material merely arranged in superposition. The print-out and silver halide compositions have a common spectral sensitivity range, e.g. 3000 to 5000 angstroms, and a common range in the visible spectrum to which they are insensitive, e.g. in the yellow safelight region. The print-out composition may comprise an organic halogen compound / arylamine composition, e.g. a carbon tetrabromide /diphenylamine composition, or a diazo composition containing 4<SP>1</SP>-diazo-2<SP>1</SP> :5<SP>1</SP> -diethoxybenzanilide zinc chloride salt, 1:3:7-trimethyl xanthine, thiourea, acrylic acid amide, triethanolamine and 2:3-dihydroxy-naphthalene. In an Example, (10), a mixed print-out and silver halide composition is made by mixing a silver chloride emulsion containing nickel and copper ions, chrome alum and formaldehyde with solutions containing (1) diphenylamine, tribromomethylphenyl sulphone and thioflavine in methanol/ methylene chloride and (2) diphenylamine and carbon tetrabromide in aqueous gelatine.
