Abstract: 996,964. Dip sticks. OUTBOARD MARINE CORPORATION. Oct. 20, 1961 [Nov. 11, 1960], No. 38907/60. Heading G1H. A gauge 10 for use with a tank 20 which is of predetermined volume and configuration and which is to be filled with a mixture of two liquid components in a desired ratio, indicates, when the tank is already partly filled with the components in the desired ratio, the quantity of one component which must be added before the tank is filled up with the other component in order to fill the tank completely with the mixture in the desired ratio. The tank 20 has a filler opening 24 from which a short sleeve 26 extends downwards providing a neck which sharply defines the capacity of the tank. The gauge 10 has a handle 12 and its body 16 is provided with graduations 18 having numerical designation progressively increasing from the handle end to the opposite end. Each graduation indicates when the gauge is wetted on insertion in the tank so that the lower end of the gauge rests on the bottom of the tank, the amount of one of the components to be added to the tank before filling up the tank with the other component.

Title: Process for preparing a soluble tea product
IPC: A23F3/16
Filed: 1962-10-17
Abstract: A powdered tea extract which is easily and completely soluble in water having a temperature between 5 and 15 DEG C. to form a clear aqueous solution which may be chilled to 0 DEG C. without precipitation of any tea solids, is prepared by making an initial aqueous tea extract from tea leaves, cooling the extract in order to precipitate a portion of the tea tannins which it contains and separating the precipitated tannins by clarification of the extract as by centrifuging, subjecting the separated tannins to at least one oxidation reaction by an oxidising agent, mixing the oxidised tea tannins with the clarified extract and drying the resulting mixture. Preferably the tea tannins are subjected to a first oxidation performed at a pH of 5.5 to 7.5 (adjusted by sodium or potassium hydroxide) employing oxygen, an oxygen-containing gas, hydrogen peroxide, ozone or an ozone-containing gas, and the consequent darkening of the tannins produced by the oxidation is bleached out in a second oxidation reaction employing ozone, an ozone-containing gas or hydrogen peroxide.  Volatile aromatics are stripped from the initial aqueous tea extract and, after condensation, are added to the resulting solution of oxidised tea tannins with the clarified stripped tea extract.  The specification describes in detail several procedures for the oxidation and bleaching reactions involving packed-columns and autoclaves under continuous, series-connected and batch operations.  Thus, the extraction of 45.4 Kg. of tea leaves results in the production of about 5.4 Kg. of tea tannins from the centrifuging operation and about 10 Kg. of clarified concentrate at 5.6% solids concentration are obtained. The tea tannins solids are standardised to a 12% dispersion and, after adjustment of pH, are oxidised and bleached to give 5.7 Kg. of tannin solids at 9.85% concentration.  The two liquors are combined and spray dried to yield 15.7 Kg. of tea powder.

Filed: 1965-09-20
Abstract: In a process wherein a whole petroleum crude oil or a topped petroleum crude oil is converted to desired end products by a combination of coking, hydrocracking and reforming steps, the entire feedstock is subjected to a coking step and thereafter the entire liquid product therefrom is subjected to a hydrocracking step. The coking is preferably a fluidized process. The hydrocracking may be fixed bed or fluidized; it may use nickel, cobalt, platinum or palladium on silica-alumina, or a molecular sieve plus a platinum group metal, or it may be a two-stage (hydrogenation, followed by cracking) process.  The reforming catalyst may be platinum on alumina or silica-alumina and may contain chlorine and/or fluorine.  The reforming may result in a net gain of hydrogen which is recycled to the hydrocracking stage.

Apparatus for synchronizing cinÚ film with independent sprocket holed magnetic tape comprises means for forming a loop in the tape between capstan and either reel, the size of the loop depending upon the relative speed of capstan and a sprocket 5 constrained to run at film speed, and a roller 6 on a pivoted arm, the position of which determines the film speed. The sprocket 5 is driven by the tape, but is constrained by an electromagnetic escapement controlled by impulses from the film apparatus. In one form (Fig. 2, not shown) the escapement comprises a slide engaging the or other sprocket teeth and moved by an electromagnet, but alternatively (Fig. 5, not shown) the sprocket is attached to a toothed, ferromagnetic, wheel co-operating with a pair of electromagnetics which lock the wheel by magnetic attraction and release it at the appropriate rate. The impulses may be generated by a commutator, or, preferably, by a pair of contacts engaging the sprocket holes of the film. The speed of the film is controlled either by a resistance in the driving motor circuit, comprising an arcuate resistor swept by a slider on the arm carrying roller 6 (Fig. 3, not shown), or by the open/closed ratio of a pair of contacts in the motor circuit, the ratio being determined by the mean position of the arm which in this case continuously oscillates and operates the contacts.

Abstract: 1,111,389. Coiling wire on tubes. SIMONCARVES Ltd. (K. Vogt). 5 Jan., 1966 [7 Oct., 1964], No. 40872/64. Heading B3E. A method of coiling a tensioned wire about a tube comprises supporting the tube for rotation about its axis, clamping one end of a wrapping wire to a clamping point adjacent the tube, positively rotating the clamping point and the tube about the tube axis to thereby wind wire on the tube, tensioning the wire as it is wrapped on the tube by supplying wire to the tube at a speed less than the peripheral speed of the tube, and applying a counter-stress to the tube adjacent the position of winding on the wire to reduce strain in the tube due to the tension in the wire. Wire 43, from a reel 42, to be wound on a tube 8 supported vertically on a table 3 rotated through variable ratio drive means 35 from a motor 36, is clamped to the table 3 by means 44. The wire 43 passes from the reel 42 around multi-grooved braking rollers 22, 23 on a carriage 13 and over a guide pulley 28 to the tube 8. The pulley 28 is carried by an arm 27 pivoted, e.g. adjustably, at one end to an arm 20, e.g. telescopic, longitudinally displaceable in the carriage 13 and carrying rollers 26 engaging the tube 8, and a compression-spring rod 24 carried by the carriage 13. The carriage 13 is moved axially of the tube 8, during winding, by hoisting means 14, 15. The braking roller 22 is driven through a shaft 38 from the motor 36, and the roller 23 from the roller 22, the speed at which wire is unwound from the rollers 22, 23 being less than the circumferential speed of the tube 8. To maintain constant the prestress in the wire 43 passing from the rollers 22, 23 to the tube 8, the rod 24 controls by means 25, 31, 32 the variable ratio means 35 in the drive to the table 3. Two coils at each end of the winding on the tube are clamped together by clips 45.
