Title: Improvements in or relating to rope-gripping mechanism
IPC: F16G11/00
Filed: 1945-11-02
Abstract: 600,876. Rope-grips. LOWE, C. S. Nov. 2, 1945, No. 29173. [Class 78 (ii)] The rope-gripping mechanism is of the type having a jaw 22, Fig. 4, fixed to the frame of the wagon 42, Fig. 3, and a movable jaw 24, Fig. 4, which is caused to grip the hauling rope 16 through the medium of cam 64 when the two parts of the hanger are moved relatively. It is characterised in that the cam 64 is fixed on the side of the movable hanger, the movable jaw 24 is constituted by one end portion of a double-ended lever 30 that is pivoted at 32 to the fixed jaw, and the actuating means comprises a jaw-actuating member 35 operated by the cam actuated under gravity or mechanically, whereof one end portion is pivoted at 34 to the other end of the double-ended lever 30 and wherein the jaws are so spaced that it enables (a) support and depression pulleys to lie below and above the jaws; (b) in the case of under-haulage, an angle wheel to be situated between the jaws and the hanger; (c) in the case of over-haulage, angle wheels to lie above the wagon on both sides of the jaws. Figs. 3, 4. The bicable ropeway bucket vehicle is made in two p rts which move relatively to each other so as to effect the closing of movable jaw 24 against fixed jaw 22 to grip haulage rope 16. The top part 36 comprises track wheels 12 ; and hanger bar 11 to which is fixed jaw 22, the latter carrying at pivot 32 the movable jaw 24 which pivots again at 34 under the action of a double link 35 bridged by roller 74. The lower part comprises stem 48 which is fastened at the bottom to framework 60 of the bucket and at the top to sliding box 50 containing coupling rollers 56, 58; which stem carries cam member 64. As these top and lower parts move relatively under the action of the load, roller 74 is held close to cam 64 by the action of compression spring 76 and its movement is transmitted by double link 35 to cause movable jaw 24 to open or close. Alternatively, the relative motion which actuates the jaws may take place between a onepiece hanger moving relative to the wagon. Figs. 6, 7, 8. The movement of the cam 64 is controlled by the movement of weight 86, Fig. 6, which pivots at 88 in bracket 89, Fig. 8, fixed to top hanger part 36 and which projects at its lowest point 90 into slot 92 contained in the lower part 48 of the framework so that, as the weight 86 is moved over by hand from left to right (Fig. 6), pin 90 rotates and moves upwards and causes the jaws to separate.

Title: Image analysis
IPC: G06V10/10
Filed: 1973-06-20
Abstract: 1468168 Pattern recognition systems IMAGE ANALYSING COMPUTERS Ltd 17 June 1974 [20 June 1973 5 Dec 1973] 29237/73 and 56315/73 Heading G4R In a system in which parameters of features of objects to be recognized are determined a signal ACP is derived for each feature. Signal ACP is indicative of the position within the scanned field of a point defined by the intersection of, for example, a notional horizontal line extending from the lowest part of the feature and a vertical line extending from the right-most part of it. The ACP signal is stored during a first frame scan and used during a subsequent frame scan to gate the parameter value to a store for subsequent use in recognition. Other parameters relating to the same feature may be gated out similarly in respective later scans. When the parameters for that feature have all been gated the ACP signal for the next feature is determined and stored and so on. The features may be on a microscope slide and scanned by a c.r.t. The scanner output is limited to provide contrast amplitude pulses to a feature measuring unit and to circuit determining the ACP signal. A cyclic store may be interposed so that the portion of the field containing the feature under consideration may be 'frozen' until all the parameters have been calculated. The determination of the parameters and the ACP signals is as described in the Specification 1,323,556. Should a preliminary measurement of the parameter value indicate that the feature is not of interest the ACP signal is erased and the ACP signal of the next feature determined. The parameters for any one feature are calculated during successive frame scans and may include, for example, area and perimeter length. The selection of the parameters to be calculated is controlled by a circuit which, inter alia, defines a window surrounding the ACP point and which may display this window on a monitor displaying the scanned field. The parameter values gated by the ACP signal pass via a second gate, controlled by the window signal, to a unit which computes the shape factor for the feature in accordance with the values. The shape factor is fed to the recognition unit.

Title: Improvements relating to protective metal silicate coatings
Inventor: MORRIS LESTER
IPC: C04B24/12
Filed: 1953-02-02
Abstract: A liquid curing agent for alkali metal silicate coatings containing finely-divided metal such as zinc or aluminium comprises a butylamine salt of phosphoric or hydrochloric acid, 4 to 20 per cent of the total volume of water and at least 50 per cent of the total volume of one or more of water-soluble alcohols, glycols, ethers, and ketones. Typically n-dibutylamine is dissolved in methylated spirits or isopropanol with a small amount of water and commercial phosphoric acid is slowly added thereto with stirring.  If dibutyl amine dihydrogen phosphate is dissolved in methylated spirits two coatings are required to effect curing, while the use of the corresponding chloride although requiring only one application results in a more brittle and less adherent cured coating.

Abstract: 772,222. Colour television receiver tubes. HAZELTINE CORPORATION. Oct. 17,1955 [Nov. 19, 1954], No. 29593/55. Class 39(1). [Also in Group XL(b)] A cathode-ray tube beam focusing unit 55 comprising a magnetic cylindrical shield 60 having a plurality of high reluctance baths (e.g. air gaps) spaced around the shield (of which three, 61, 62, 63 are shown) is provided with a pair of magnetic shunts 64, 65 of low reluctance material which are adjustably retained by spring elements 66, 67, over two of the high reluctance paths which are spaced by 90 degrees along the periphery of the shield. Adjustment of the shunts varies the reluctance of the focusing unit and produces a slight displacement of the effective magnetic lens formed by the unit and therefore allows the positions of the raster to be varied without appreciable effect on the focus of the beam. To extend the range of adjustment additional shunts, e.g. a second pair diametrically opposed to the shunts 64, 65, may be employed. The invention is employed in a colour television receiver to allow adjustment of the registration of the component colour images from a plurality of tubes when such images are confined on a viewing screen.

Title: Separation of factors a, b and z from antibiotic e129
Inventor: SMITH ERNEST LESTER
Filed: 1957-09-20
Abstract: Antibiotic E129 Factors A, B and/or Z are separated from antibiotic mixtures containing two or more of said factors, especially crudes obtained by fermenting an E.129-producing strain of Streptomyces ostreogriseus, by partition chromatography using as static liquid phase a mixture of water and a water-miscible substantially polar organic solvent and as mobile phase a substantially non-polar water-immiscible organic solvent, eluate fractions containing in turn Factors Z, A and then B.  It is preferred that the crude E129 be given a preliminary treatment to remove part of the Factor A and/or part of the Factor Z components.  Factor A is removed by treatment with a preferential solvent for Factor A, e.g. ethyl acetate.  Factor Z is removed by acid extraction in accordance with Specification 826,704.  The ethyl acetate solution remaining after crystallization of Factor A may be given the acid extraction treatment.  Solvents for the mobile phase are aromatic hydrocarbon solvents such as benzene and toluene, or a mixture thereof, preferably with a poor solvent for the E129 factors, e.g. cyclohexane, carbon tetrachloride and isopropyl ether.  It is preferred to use the mixed solvents to remove the Factors Z and A, and the undiluted solvent to remove Factor B. The static phase consists of a mixture of water and an alcohol, e.g. methanol and water in proportions of 2 : 1 to 1 : 2.  The absorbent for the static phase is an absorbent having no adsorptive capacity for Factors A, B or Z, e.g. kieselguhr, powdered cellulose, starch or silica.  6 to 3 parts of the static phase is used to 4 parts of the kieselguhr and/or powdered cellulose.  It is preferred that the crude E129 be dissolved in the static phase and that this solution should occupy the upper half of the absorption column.  A preferred method is to develop with cyclohexane benzene (3 : 5) until Factors Z and A have been recovered, followed by benzene to remove Factor B.  The separated fractions may be further purified.  Specifications 793,797, 799,053 and 820,657 also are referred to.

Title: Process and device for the preparation of polymer dispersions having a low monomer content
IPC: C08F2/22
Filed: 1976-07-16
Abstract: Polymer dispersions are prepared by emulsion or suspension polymerisation with opening of C-C double bonds of at least one monomer in aqueous liquor, decompression of the polymer batch and discharge and condensation of the gaseous products. In at least two vertical, rotationally symmetrical containers connected in series, the dispersion is sprayed radially, in the form of a hollow cone or disc, against the container wall; the droplets have a maximum diameter of 6 mm. They are deposited on the container wall and collected in the lower part of the container. The gaseous substances are drawn out of the spray device above the dispersion exit. The gaseous substances are passed from container to container in only one direction and the dispersion in the opposite direction. This process allows physiologically unacceptable substances to be removed directly after the polymerisation, using comparatively low apparatus volumes. <IMAGE>
