Patent GB-1096271-A (GB)
Title: Apparatus for assesing the weight of contents of large vessels
Inventor: CHAPLIN ROBERT DE VILLIERS
IPC: G01G19/00
Filed: 1963-06-21
Abstract: 1,096,271. Weighing apparatus; load cells. ARTHUR GUINNESS SON & CO. (PARK ROYAL) Ltd. June 17, 1964 [June 21, 1963], No. 24741/63. Headings G1N and G1W. The weight of the contents of a vessel is assessed by supporting the vessel on joists carried by a fixed structure, measuring the elastic bending of one of the joists relative to a reference beam which is hingedly supported by pins adjacent its ends from the bending joist, and co-relating the measured bending with experimental results obtained with known weights in the vessel. The bending may be detected by hydraulic means in which case a bellows, piston or diaphragm arranged mid way along the beam and between the bending joist and the beam affects the height of a liquid column in a tube in accordance with the bending, thereby to provide a liquid level indication of the weight. Alternatively, electrical detecting means may be employed in which case a strain gauge or a capacitance unit may be used. The capacitance unit is such that a plate of a capacitor is connected to move with the bending joist, this plate being associated with a further capacitor plate fixed to the reference beam. When several vessels are mounted on associated joists which are arranged on the fixed structure so as to mutually interact, supplementary weight detectors may be suitably arranged to compensate for the bending of a joist associated with one of the vessels due to the weight of the contents of the other vessels.

Title: Apparatus and method for pressing glass sheet and plastic assemblies
IPC: C03C27/12
Filed: 1959-07-21
Abstract: 919,701. Laminating. LIBBEY-OWENSFORD GLASS CO. July 21, 1959 [July 30, 1958], No. 24954/59. Class 140. Apparatus for pressing a bent glass-plastic assembly composed of two sheets of glass and an interposed layer of non-brittle plastic material comprises a frame, means for rocking the frame about a substantially horizontal axis, a plurality of pairs of pressing rolls including an upper roll and a lower roll journalled on the frame to turn about spaced-apart axes substantially parallel to said horizontal axis, the axes of all the rolls and the said horizontal axis lying in a common plane, and means for passing a glass-plastic assembly between the rolls of said pairs to effect pressing, and is characterized by the provision of means for resiliently mounting certain pairs of the rolls in the frame so that the rolls of each pair move as a unit in the common plane, and means for off-setting the weight of the rolls on the glass-plastic assembly during rocking of the frame and the rolls as the assembly passes, to prevent the weight of the rolls from being added to the pressure normally exerted by the rolls upon the assembly. As shown, the frame C is pivotally mounted on a tubular shaft 116 and a stub axle (not shown) on the other side. Pairs of rubber-tyred rolls (not shown) are mounted in the frame C, and the lower roll of each pair driven by a sprocket drive from the shaft 151. The rolls are mounted in cradles, the two cradles of each pair of rolls being joined by means of levers 190-3 and 195-8 which extend diagonally across the bottom and top of the frame C, and are connected at their free ends by links 201. The levers 195, 196 and 197 are connected with a slide-bar 227 through coil-springs 234. A ballbearing roll 235 is in rolling contact with the cam surface 236 so that as the frame C approaches the vertical, the slide-bar 227 is raised and increases the tension in the springs 234, and as it descends on the other side, the tension is reduced again, so compensating for the varying effect of the weight of the rolls and their supports. Certain of the pairs of rolls may be mounted for swinging movement into a position in which the axes of the rolls are in the same plane as but no longer parallel with the axes of some or all of the other rolls, to enable the rolls to follow the curvature of an assembly that is curved in both directions. A glass-plastic assembly may be passed through one such apparatus, then through an oven, and finally through another such apparatus.

Title: Improvements in or relating to signal amplifying circuits
Inventor: STATT STANLEY
IPC: H03G7/02
Filed: 1959-07-21
Abstract: 875,743. Valve and transistor pulse amplifying circuits. INTERNATIONAL COMPUTERS & TABULATORS Ltd. June 15, 1960 [July 21, 1959], No. 24976/59. Class 40(6) In a pulse amplifier in which pulses are passed over a grid condenser 3 and leak 5 to the grid of a valve 2, the period of paralysis due to grid current when an overlarge pulse is applied is reduced by passing the change in grid voltage to a second valve 11 via a lowpass filter 12, 13. The change in cathode current of the valve 11 causes a change in cathode voltage of the valve 2, due to the common cathode resistor 9, which offsets the effect of the grid voltage change in this valve. The arrangement may also be applied to transistors. The arrangement provides heavy D.C. negative feedback and constitutes an amplifier which, by omission of the input condenser may be directcoupled to a preceding stage.

Filed: 1939-09-07
Abstract: 533,528. Power transmission for motors. CHRYSLER CORPORATION. Sept. 7, 1939, Nos. 25231 and 25232. Convention dates Sept. 3, 1938, and May 17, 1939. [Class 80 (ii)] In a power transmission system for driving motor cars the crank-shaft 10 drives the impeller member 14 of a kinetic hydraulic coupling to which it is connected by a supporting journalling member 13 formed with a member 23 which carries an anti-friction ball bearing 24 which provides a support for a hub 20 to which is fixed the runner 16 of the hydraulic coupling. The hub 20 also supports the shrouding 18 of the coupling in fluid-type manner and is attached to the driving-member 30 of a friction clutch which drives the input shaft 11 of a variable speed transmission device C of the motor. The shaft 11 is connected to the driver-disc 33 of the clutch which is controlled by a pressure plate 31 which can be moved against the action of springs 32 to throw-out the clutch by the action of levers 36. The forward end of hub 20 is fitted with roller bearings 26 to support the forward end of the input shaft 11, and the rear end of the shaft 11 is supported by ball bearings 27 carried by the transmission device C. The rear end of the hub 20 is supported by roller bearings 29 on the shaft 11. The ball bearings 24, 27 provide the entire support for the shaft 11 and hub 20 and so allow universal tilting of said shaft and the hub as a unit to compensate for minor misalignment between the driving shaft and transmission. The throw-out mechanism 35 for the clutch is slidable on a sleeve 37 secured by fasteners 38 to the casing of the transmission C. Internally this sleeve is formed with a tapered clearance 39 to permit tilting of the shaft 11, and an oil packing may be fitted in the clearance. The sleeve 37 may be formed with an internal thread 41 of such hand that the rotation of shaft 11 tends to urge oil back towards bearing 27.

Title: Method of obtaining adrenocorticotropic hormone preparation
IPC: A61K38/35
Filed: 1953-09-14
Abstract: An adrenocorticotropic hormone preparation of increased potency is obtained from a protein mixture of the hormone-active and inactive components by selective adsorption with a carboxylic-type cation exchange resin.  The starting material, which may be a crude extract of the pituitary gland, is dissolved or suspended in a liquid carrier, e.g. ethanol dioxan, ethylene glycol, acetone, isopropanol but preferably water, which is passed through the resin, the active component being held in the resin and the inactive component percolating through.  The separation may be effected at pH 3.5 to 9.0 but a preferred pH of 8.0 to 9.0 is maintained by a buffer, e.g. alkali-metal carbonate-bicarbonate.  After removal of the inactive component by washing the resin with liquid carrier of pH 8.0 to 9.0, the hormone-active fraction is eluted from the resin by continued percolation with buffered liquid carrier.  Unhydrolysed protein mixture is removed at pH 8.0 to 9.0; acid-hydrolysed mixture at pH over 10; enzyme-hydrolysed mixture at pH 9.1 to 9.75; acid- and enzyme-hydrolysed protein mixture at pH 9.1 to 9.75, the first fraction eluted being enzyme-hydrolysed hormone.  The percolate containing hormone-active component may be treated preferably by lyophilization, to yield a dry powder.  Suitable resins are " Amberlite " (Registered Trade Mark) XE-97 and IRC-50, which may be in salt form, preferably in a finely divided state and packed in a column.  The starting material may be unhydrolysed or hydrolysed, e.g. by acid or proteolytic enzyme hydrolysis, or both; or it may be purified with cellulose or oxycellulose by batch adsorption and elution techniques.  Specification 681,389 is referred to.
