Abstract: 1346248 Pneumatic conveyers ETABS PIERRE BEVENGUT 19 April 1971 [11 Feb 1970] 21545/71 Heading B8A [Also in Divisions G3 and F1] Flow controller, which is suitable for use as an atomizer or as a pneumatic conveyer for powdery materials, comprises a tube C through which the fluid to be conveyed is controllably conducted, and a nozzle T through which a controlling fluid is conducted. The pressure of the controlling fluid is variable and/or the tube and nozzle are relatively adjustable to so permit the controller to attain a desired one of two states; in the first of these states the pressure of the controlling fluid is low in the region of the tube nozzle and so a zone of suction is created at the nozzle resulting in an outflow through the tube; in the second of the two states, a high pressure zone of compression is created at the nozzle resulting in a stoppage of the outflow from the tube C. The nozzle may have a cylindrical portion between the convergent-divergent portions thereof. Preferably, it is in the form of a venturi. Fig. 2, not shown, diagrammatically depicts an atomizer whilst Figs. 3 and 4, not shown, depict constructions of a controller wherein the tube and nozzle are relatively movable. Fig. 5, not shown, indicates a supply arrangement for the controlling fluid whereby the fluid can be given two discrete levels of pressurization.

Title: A variable cam suitable for the control of the progression of a part of a machine tool
IPC: F16H53/04
Filed: 1957-07-09
Abstract: 849,369. Cams. CRI-DAN. July 9, 1957 [Jan. 11, 1957], No. 21774/57. Class 80 (3). An adjustable cam actuating a follower 19 comprises an inner eccentric 7, an outer eccentric 1 of substantially equal eccentricity, and an interposed sleeve 9 which is rotatable on the eccentric 7 and is rectilinearly slidable in a mortise 11 in the eccentric 1. Rotation of the eccentric 7 relative to the eccentric 1, by means of a knob 12, causes the outer eccentric to move along a line at right-angles to the mortise 11 and thus varies the compound eccentricity. The angular position of this line relative to the shaft 6 may be adjusted either by direct manipulation of the eccentric 1 (Fig. 11, not shown) or by means of a knob 15 on the shaft of a plate 4 having a radial mortise engaged by a tenon 3 on the eccentric 1, the tenon 3 lying at rightangles to the mortise 11. The follower 19 may actuate the tool carrier of a thread-cutting machine when the cam-shaft 6 is rotated through an angle of 90 degrees or less. The knobs 12, 15 carry scales to facilitate adjustment of the cam to vary respectively the throw of the cam and the arcuate portion thereof which is engaged by the follower. Locking- means such as a nut 18 may be provided. The provision of the sleeve 9 is stated to simplify the scales for the adjusting-knobs. Specifications 624,612 and 636,664 are referred to.

Filed: 1928-07-27
Abstract: 322,170. Woelm, M. July 27, 1928. Hypodermic injections.-Solutions of mixtures of suprarenal preparations such as adrenalin with p-aminobenzoyldiethyl aminoethanol hydrochloride, alpha - dimethylamino - # methyl butanol hydrochloride, or benzoylethyltetramethyl diaminoisopropanol hydrochloride are obtained by the addition of disodium phosphate, which prevents decomposition of the suprarenal preparation for a short time, and thus renders the solutions suitable for injection. The components may be put up in double ampoules, so as to separate either the mixed preparation from the aqueous solution of disodium phosphate, or all the solid components from the solvent. The addition of sodium bicarbonate to mixtures of suprarenal preparations with p-aminobenzoyldiethylaminoethanol hydrochloride or with similar anµesthetics is referred to.

Title: Method of and device for identifying colours
IPC: G01J3/46
Filed: 1973-05-08
Abstract: 1436638 Facsimile systems FRANZ MORAT GmbH 8 May 1973 [13 May 1972] 21948/73 Heading H4F [Also in Division G1] A system for identifying colours including an opto-electronic scanning device for the production of electrical analogue signals proportional to the primary colours present includes division and/or addition and/or subtraction circuits for deriving further signals from the analogue signals and a logical evaluation circuit for the two sets of signals so that separation zones are formed between colours in which no colour identification is possible. A drawn pattern of a grid type, e.g. the pattern to be used in knitting or weaving technology, is scanned by a device such as that shown in Specifications 1,170,947 and 1,196,600 and the reflected light is detected by three photo-cells 35 rendered sensitive to red, blue and green light by colour filters. The detector outputs after amplification at 37 are fed to further respective amplifiers 39 which provide analogue signals representative of the primary colours and also to difference amplifiers 41, 43, 45 which also provide the absolute values of the differences. The amplifier outputs are then fed to an analogue to digital converter which acts as an amplitude discriminator and normalizer and which includes three NAND gates 51, 53, 55 for each amplifier. The outputs from the converter are then applied to a logic evaluation device 49 which includes a NAND gate 57 assigned to each colour channel i.e. the three primary colours, three mixed colours and white. The circuitry is such as to function in accordance with the following "truth" table where r, b, g are primary colour signals lying above a threshold "S", Fig. 5, r, b, g are primary colour signals below the threshold and /r - b/, /b - g/, /g - r/ are the differences of the colour fractions of the mixed colour above a threshold and /r - b/, /b - g/, /g - r/ the differences below the threshold value. Thus for the colour quadrant for red, blue and magenta, Fig. 5 shaded areas thereon indicate zones in which a "white" signal is produced if the colour lies therein and there is no identification. Details of difference, addition and division circuits are described Figs. 12, 13, 14 (not shown) and various colour diagrams with differing zones may be formed Figs. 6-10 (not shown) using different logic circuits.

A coil annealing furnace comprises one or more upwardly extending bases each of which is associated with a heat exchanger located externally of the furnace and provided with at least one inlet pipe and at least one valve controlled discharge pipe, the pipes extending through the base, and an open end of the inlet pipe disposed in a diffuser duct so that, on the commencement of cooling, a proportion of the gaseous atmosphere flows through the heat exchanger where it is cooled and then returned to the furnace. As shown, a furnace hearth 1 has a raised base 2 having a hollow plate 3 supporting a diffuser comprising two superimposed annular plates 4, 5 secured together by spacer bars 6 and having openings 4a, 5a. The diffuser also comprises a system of blades secured to the underside of the plate 4 and a fan is disposed in a central opening. A heat exchanger 18 is located below the hearth and is provided with an inlet pipe 19 and a discharge pipe 20, the latter having a valve 21. Coils 22 for annealing are placed on the plate 5, the cover 24 sealed in position, and the temperature raised. When the heating is completed the valve 21 in the discharge pipe is opened with the result that a proportion of the hot gases passes through the heat exchanger, is cooled, and returned to mix with the remainder of the atmosphere and the cooling of the coils is expedited. In a modification, Fig. 4 (not shown), a single plate 5 is used and in a further modification, Fig. 6 (not shown), the position of the outlet of the discharge pipe is altered.
