Title: Improvements in and relating to Apparatus for Recording an Image of the Surface of a Body
Inventor: SYKE GEORGE
IPC: G03B15/00
Filed: 1965-12-20
Abstract: 1,179,404. Photographic apparatus and method. BRITISH IRON & STEEL RESEARCH ASSOCIATION. March 8, 1967 [Dec. 20, 1965], No.53812/65 Heading G2A. Different images of a surface of an elongate sheet or strip material are formed by directing light on to a selected area of the surface from different directions, and exposing different areas of film to reflections of light from the different directions. In a first embodiment, a first image of selected areas of a strip (1) is formed on a film F as the strip passes through an area P by using a lens L1 and a first aperture of a twin apertured rotating shutter disc 6; and a second image of the same area is then formed as it passes through an area Q, using a lens L2 and the second aperture of shutter disc 6. Light is directed on to area P transverse to the direction of travel at an off specular angle of 15 degrees by a elliptical reflectors (4) positioned at each side of the surface, and on to area Q along the line of travel at an off specular angle of 70 degrees by a parabolic reflector (6). The film F may be driven via a clutch K, the amount of exposure adjusted by a slit S, and the exposure terminated by a shutter H. The pair of images produced may be developed in a high speed processor and viewed together so that defects in the surface may be seen; lenses L1 and L2 are preferably arranged on either side of the axis of film F so that these defects may be distinguished from marks formed on the film during processing. The process may be used for high-speed inspection of rolled steel strip; by using a pair of synchronised imaging units a 100% inspection may be obtained. In an alternative embodiment two imaging units in which the shutters are locked open may be used to form images of the light reflected from different directions.

Title: Tone signal repertory dialer
IPC: H04M1/276
Filed: 1966-12-12
Abstract: 1,143,125. Repertory diallers. DASA CORP. 12 Dec., 1966 [28 Dec., 1965], No. 55467/66. Headings H3T and H4K. A repertory dialler incorporating a gate opened for a time dependent on which key of a keyboard is depressed, to pass an associated number of pulses to a magnetic recording head has means responsive to the gated pulses to produce corresponding multifrequency tones. The arrangement shown has four different modes of operation selected by a knob (not shown) controlling contacts MS1 to MS10. In a recording mode, row and column identifying signals on one out of four lines a to d and one out of three lines A to C are each converted to binary code and stored in flip flops FF1, FF2 and FF3, FF4 respectively. A pulse generator is triggered and applies pulses to a four stage binary counter having least and most significant portions 25 and 26. A comparator 23 compares the code in the flip flops FF1 and FF2 with the codes produced by the stages CS1, CS2 in the portion 25 of the counter, and responds on coincidence to give an output on one of four lines a m to d m the particular line being dependent on the numerical value. A comparator 24 similarly compares the column data and on coincidence gives an output on one out of three lines A m to C m. When the two comparators respond simultaneously, i.e. when the counter records that the number of pulses indicated by the key has been produced, an AND gate 29 responds to inhibit the generation of further pulses. The pulses from the generator are also supplied to a transducer which records them on magnetic tape as described in Specification 1,143,124. The machine cycles repeatedly entering successive digits as they are set on the keyboard. In the automatic dialling mode the correct portion of the magnetic tape is selected and a call button depressed. The corresponding pulses are read from the tape and set the counter 25, 26 and since contacts MS1 to MS8 are open and thus connect a positive supply, the comparators respond and give their outputs. In a dialling mode whether automatic (controlled by the tape) or under key control (as during recording) the outputs from the comparators select a relay winding W1, W2, W3 or W4 and a relay winding W5, W6 or W7 closing contacts to vary the inductance of a pair of tank circuits in a multi-frequency generator. Near the completion of a dial cycle the generator is shock excited to send the multifrequency tones to line. The repertory dialler includes a dual frequency oscillator as described in U.S.A. Specification 3,184,554. As shown one contact of a set W1S to W4S and one contact of a set W5S to W7S are simultaneously closed to select the inductances of tank circuits TC1 and TC2. With a switch contact TS1 in the position shown the capacitors of these tank circuits are charged up by a potential developed across a varistor 45. When the contact TS1 is moved to its other position the resulting oscillatory discharges are sustained by a transistor Q1 the feedback paths of which include amplitude limiting varistors 54 and 55.

Abstract: 1442415 Free-flowing sodium sulphate composition BRITISH CHROME & CHEMICALS Ltd 29 Nov 1974 [7 Dec 1973] 56844/73 Heading C1A Sodium sulphate composition containing sodium dichromate as impurity, chrome saltcake, is subjected to a reduction reaction or double decomposition, or a combination of both, so as to convert the sodium dichromate to a less hygroscopic chromium compound. The reaction may be carried out before, after or during the drying of the damp saltcake, which is separated from sodium dichromate liquors and washed. The saltcake may be carried to a drier after washing by means of a screw conveyer to which the reactant may be added. The reaction is preferably carried out in the presence of moisture. Double decomposition is achieved by treatment of the moist chrome saltcake with a reagent, preferably the salt of an acid and ammonium and potassium sulphates in particular are preferred. Reaction with ammonium sulphate is exemplified, the ammonium dichromate formed undergoes reduction to chromic oxide above 600 C. Ammonium salts are used in an amount of from 0À5 to 1À0 times and potassium salts in an amount of from 0À5 to 3À0 times the theoretically required amount which would give complete reaction with the sodium dichromate present. The reducing agent may be chosen from the salts of sulphurous acid, sulphur dioxide, sulphurous acid itself, sodium dithionite, and pyrogallol, and is preferably sodium bisulphite or metabisulphite. The preferred ratio of addition is from 0À1 to 20 moles per mole of dichromate, although usually from 0À5 to 3À0 moles is used. The product is a stable free-flowing sodium sulphate composition.
