Filed: 1969-06-07
Abstract: 1278329 Weighing apparatus SERVICE D'EXPLOITATION INDUSTRIELLE DES TABACS ET DES ALLUMETTES 7 June 1969 [7 June 1968] 27461/69 Heading G1W In a method of weighing out a succession of complete doses of predetermined weight each complete dose is weighed out in a preliminary cycle and a successive adjustment cycle. During the preliminary cycle a preliminary dose having a weight less than the required complete dose is applied to a weighing device before the apparent weight of such dose is temporarily reduced by applying a counterweight to the weighing device for a period of time extending into the adjustment cycle then, during the adjustment cycle in which the preliminary dose is topped up by an adjustment dose to the required weight of the complete dose, a regulating means is actuated only when adjustment to complete the dose is effected in a predetermined time period, the regulating means being arranged when actuated to adjust the next preliminary dose in such a way that completion of this next dose is effected in a time period greater than said previous time period. During the preliminary cycle, the weighing device may be locked so as to prevent interfering oscillations and the period for which the device is locked may overlap the time for which the counterweight is in operation. During the adjustment cycle the counterweight may be removed after the adjustment dose is started and the adjustment dose is completed only when a continuous end-of-weighing signal is obtained. The weighing device may comprise a counterweight 12 in the form of a ring which can be removably placed on a pointer 14 of the weighing device when the apparent weight of the preliminary dose is temporarily reduced by a pair of hooks 2a, 2b mounted on a shaft 1 which is rotatable by a solenoid valve-operated piston and cylinder arrangement 8, 9.

Title: Improvements in or relating to method and apparatus for continuously transforming a dispersion of a rubbery material into a sheet
Filed: 1947-10-16
Abstract: A dispersion of rubbery material such as synthetic rubber is continuously transformed into a sheet by producing a slurry of discrete rubbery crumbs, depositing a layer of the crumbs upon a pervious moving surface, washing the layer of crumbs upon the moving surface and pressing the layer of crumbs into a sheet.  The rubbers may be polymers of butadiene 1,3, isoprene, piperylene, or 2,3 dimethylbutadiene -1,3; or copolymers of butadiene -1,3 with acrylonitrile, stryene, methyl methacrylate, or methyl isopropenyl ketone; the polymerization step having been effected in the presence of sodium myristate, palmitate or oleate.  In an example, a butadiene-styrene dispersion is treated with sufficient brine solution in a stirrer fitted tank to cause the size of the particles to increase to about 0.4 microns.  The dispersion is then passed to a further tank where it is coagulated under controlled conditions with sulphuric or acetic acids after a stabilizing agent such as sulphonated rosin, sulphonated pine oil, sodium isopropyl naphthalene sulphonate, glue, gelatine, dextrin, starch or colloidal clay has been added.  The pH of the slurry is adjusted in another tank and then the mixture passed through a mechanical disintegrator, such as a paper beater, a Bauer mill, a Charlotte Mill or a Jordan engine.  The slurry then passes onto a pervious screen which may be made of nickel-copper alloy on which it is washed, firstly by diffused streams of water from above, then by water from below, at a temperature of 140 DEG  F.  The coagulum is then sheeted by passing through rolls where it is treated with cold water.  The sheet, now containing about 120 per cent of water is passed onto a napless open-woven wool fabric where about 75 per cent of this water is removed and finally the sheet passes through an oven heated to 140-320 DEG  F. and is then cooled by cold air.

Title: Method for detecting leaks in hollow apparatus
IPC: G01M3/14
Filed: 1965-06-30
Abstract: 1,092,855. Testing for leaks. MITSUBISHI JUKOGYO KABUSHIKI KAISHA. June 30, 1965 [June 30, 1964], No.27812/65. Heading G1S. In a method of detecting a leak in a hollow apparatus a continuous micro-crystalline film of a substance is provided on the surface of the leaking apparatus, gas is then introduced into the apparatus, and a soap or an anionic or nonionic surface active agent applied to the microcrystalline film whereby if a defect is present a fine stable film is produced on the surface as a result of gas escaping from the apparatus via the defect. In one example, a solution of 20 parts by weight of orthophosphoric acid, 80 parts of water, 5 parts of n-butyl alcohol, 2 parts of a nonionic surface-active agent was applied to the apparatus at the suspected leak region dissolving rust and organic impurities, and forming, on drying, a film of micro-crystalline iron meta and pyrophosphate. Air under pressure was introduced into the apparatus, and a solution of sodium alkyl allyl sulphonate applied with a brush. At the points of leakage a fine stable foam was produced. Various other examples are described.

Title: Cathode ray tube displays
Inventor: BOWEN DENNIS DAWES
IPC: G01K1/02
Filed: 1966-06-22
Abstract: 1,147,425. Cathode-ray tube displays. D. D. BOWEN. 19 June, 1967 [22 June, 1966] No. 27842/66. Heading H4T. A continuous display of the outputs of a plurality of transducers such as thermocouples A (Fig. 1) is produced on a cathode-ray display tube L by sampling such outputs sequentially and cyclically by means of a two-bank multicontact switch SW1, SW2, the potentials derived from which are supplied to a chopper circuit F and thence via an A.C. amplifier to the Y-deflection plates of the display tube, the X-deflection of which is produced by a sweep voltage from a one-shot multivibrator H triggered once per cycle of the switch. Due to the action of the chopper the display of the condition of each thermocouple appears as a " filledin " rectangle (Fig. 2) and by connecting the second contacts on each bank to a stabilized reference potential source D upper and lower limits may be shown on the display in the form of broken lines (Fig. 2). These limits may also be set up in a trigger circuit J so that thermocouple voltages which are outside such limits operate an alarm bell K (or issue a spoken alarm) and additionally, by means of a connection M, operate to override the normal clockwork control of a camera viewing the display so that an additional recording of a fault condition is produced. The thermocouple voltages may be backed off by the potentiometer arrangement B, C, or by the backing-off and/or normalizing arrangements of Figs. 3A and 3B (not shown). A low-frequency oscillation may be superimposed on the D-deflection sweep voltage to vary the position of the display and so prevent screen burn. When the number of thermocouples is too great to be shown on a single tube the arrangement may be modified to permit the use of more than one tube or the use of a double-beam tube.

Abstract: 408,018. Lathes. GILSON & CO., Ltd., D., and WRIGHT, A. F. J., Billet Road, Walthamstow, Essex. Oct. 7, 1932, No. 27950. [Class 83 (iii).] In an automatic screw - making machine for working on metal, ebonite and like materials in which the tools are rotated about the work and are carried on a tool plate, means are provided for storing energy when the centre of gravity of the tool plate is moved away from the centre of rotation, the energy stored being used to assist in the return movement of the tool plate. The headstock of a machine having a rotary tool holder 5 is shown, Figs. 1 and 9 ; the tools 1, 2 are adjustable towards the non-rotating work, held in collets 22, 22<a> by lever mechanism 16 which slides a collar 13 axially, moving with it a sleeve 8 with an inclined pin 10 fitting into a hole in the holder 5 so that the same is oscillated in a transverse plane when the pin 10 is moved relatively thereto. Blocks of rubber 18, 19, Fig. 3, are arranged between the tool holder and a supporting piece to which the sleeve 8 is fixed so that when relative transverse movement takes place to bring either one or the other of the tools to engage the work, the rubber blocks are compressed and the centrifugal effect produced by the tool holder being out of centre is balanced by the compressive stress on the rubber which latter assists the lever mechanism when a return to the inoperative position of the tool is required. Other resilient means are described such as springs and compressed air, the tool holder may also be mounted on a slide. Specification 336,708, [Class 83 (iii)], is referred to in the Provisional Specification.
