Title: Hydraulic jet propelled water craft driving means
IPC: B63H11/103
Filed: 1973-04-18
Abstract: 1372655 Water jet propulsion TWIN DISC Inc 18 April 1973 [2 May 1972] 18623/73 Heading B7V A water-jet-propelled vessel having a prime mover driving a water pump, a variable area jet nozzle and a reversing device movable into and out of the jet discharge is provided with a forward/neutral/reverse control lever which has connections with (a) the prime mover to vary its speed; (b) means for varying the area of the jet nozzle and (c) means for moving the reversing device. General arrangement (Figs. 1, 4).-An engine E drives a drive shaft 10 via a transmission T. Two impellers 8, 9 which are mounted on the shaft 10 within a pump housing 7 draw water from an opening 1 in the vessel's bottom 2 and eject it partly through a variable area nozzle N, which is rotatable by a ram 45 inside a housing 34, and partly through sidewardly directed steering valves V1, V2.  The reversing device comprises a pair of U- section gates 60, 61 which are slidable laterally towards or away from each other by rams 66, 67. When closed together the gates form a duct which deflects the jet backwardly under the vessel to cause it to reverse. Control arrangement (Fig. 2).-A hand lever 75 is movable into a forward position F, a reverse position R and a neutral position (solid lines). A sprocket 79 attached to the lever 75 drives a smote reprocket 80 via a chain and cable device 76. Sprocket 80 is mounted on a shaft 81 whose rotation causes movement of three arms 82, 83, 84. Arm 82 is connected to throttle linkage 85 of the engine, arm 83 is connected via a cam adjustment 87 to a valve 105 which controls the ram 45 for moving the jet nozzle N and arm 84 is connected to a valve 90 which controls the reversing gate operating rams 60, 61.  The arrangement is such that a small movement of lever 75 places the craft in either forward or reverse mode by operating the reversing gates 60, 61 (if necessary). Further movement of the lever then increases the engine speed to build up water pressure (e.g. for effective manoevering using steering valves V1, V2) and still further movement begins to open the variable area nozzle N. This opening continues in conjunction with steadily increasing engine speed.

Abstract: 481,356. Food preparations ; beverages. HILL, W. C. July 7, 1936, No. 18872. [Classes 14 (ii) and 49] [Also in Group I] Food or beverage bases are manufactured by a process involving the step of cutting unpeeled citrus fruit by a slicing operation so as simultaneously to disrupt and discharge the oil sacs of the peel and the juice sacs of the interior thereby causing the oil and the juice to be intermingled. The fruits are shredded by the sharpened and raised edges of apertures in a disc 32 carried by a shaft 25 adjustably coupled to the shaft of a motor 22, supported by a mounting 21 from a frame 6. The frame 6 rests on a tank 1 and carries an extraction cylinder 2 having a perforated portion 4 and also supports a head 11 having lugs 12 engaging in grooves in the frame and a cylindrical lower part extending into the cylinder 2, The cap portion 14 of the head is provided with a spirally arranged, downwardly directed conduit 17 of gradually decreasing area in vertical section through which the fruits are fed to the cutting disc. The lower end of the shaft 25 carries an agitator 27 operating in the cylinder 2 and is squared to engage in a corresponding recess in a steel shaft mounted in the base of the cylinder and carrying externally of the cylinder an agitator 30. In operation the tank 1 is partially filled with milk, syrup, alcoholic solution or other medium and citrus fruits are introduced through the feeding conduit 17. The oils and juices thus liberated fall into the liquid in the tank 1, the fibrous and pulp portions of the membrane and albido being retained in the cylinder 4. The citrus juices and dispersions thus made-may also be used as or in beverages, food bases, ices, and the like.

Abstract: 1508126 Packaging BRITISH VISQUEEN Ltd 25 March 1975 [30 April 1974] 18875/74 Addition to 1335304 Heading B8C A method of wrapping an article comprises advancing the article, 3, against a curtain formed by a web 9 of heat-shrinkable plastics film and a web 7 of a tear-tape material drawn from supply means 8, 6 respectively on opposite sides of the path of the article and transversely heat-sealed together at 10 to form the curtain across the path of the article. The article is then further advanced into the curtain, with further withdrawal of the material from the web supply means, until the curtain extends around the article to beyond its trailing end, the tear-tape material 7 being withdrawn non-continuously from its supply means so that a predetermined length not greater than “ of the length of the perimeter of the article in the direction of its advancement is withdrawn. The two webs are then transversely heat sealed together and severed behind the article to leave on one side the article 3a enveloped or partially enveloped in a sleeve formed from the two webs, and on the other side the two webs sealed together to form again a curtain. As described, the article 3 is advanced by a pusher 2 into the curtain and on to a conveyer 4 which, after sealing and severing of the webs by heated jaws 11, 12 and knife 13, carries the package into a shrink tunnel 5. The supply roller 6 for the tear-tape material is braked intermittently so that the tear-tape extends over <SP>1</SP>/ 9  to <SP>1</SP>/ 11  of the article perimeter. Preferably the brake is released as the jaws 11, 12 open and is applied when a stud 19 on a roller 17 actuates a micro-switch 18. Alternative actuating means, e.g. photo-electric, pneumatic, or magnetic, or marks on the tear-tape web, or a controlled dancer roll may be used to control the length of material fed. The curtain may be narrower or wider than the article fed and its end edges may be heatsealed. The tear-tape web may be wider than the other. Two webs of the heat-shrinkable material may be supplied to form a double layer. The webs may be of similar materials, e.g. polyethylene, polypropylene, or copolymers thereof.

Abstract: 727,910. Winding and reeling. WUPPERMANN GES., T. July 25, 1952 [Aug. 8, 1951], No. 18895/52. Class 83 (4). In a method of coiling narrow strip issuing from a rolling mill, the strip 1, Fig. 2, is guided into a continuously rotating cage 5, Fig. 1, and wound on the inne rface of the cage. The strip may be subsequently reeled on to a central reel core 4 which grips the trailing end of the strip as it enters the cage 5. The reel core 4 may be rotated in the opposite direction to that of the cage 5 during reeling to raise the speed of reeling. The strip 1 is guided on edge by driven rolls 2 through a guide-way 3 and between the two halves of the reel core 4 to the cage 5 which is rotated by a pinion 6 at a speed synchronized with that of the rolling speed of the strip. As the trailing end of the strip passes the rolls 2 a mechanical, electrical or optical control means causes the halves of the reel core 4 to engage the strip and as the cage continues to rotate the strip is reeled on to the reel core 4. The cage 5 is open at the top to permit access of the core 4 and strip 1 and the central portion of the box is enclosed by a disc 8 which is lowered by a compressed air cylinder 9 for removal of a coil 10. A further compressed air cylinder 12 is used to push the coils 10 from the disc 8 on to a conveyer belt 11. The reel core 4 may be off-set from the centre of the cage 5 when acting as a guide for the strip to reduce the angle of bending, the core being moved to the centre for reeling.

Abstract: 905,325. Discharge tubes. M-O VALVE CO. Ltd. May 23, 1961 [May 30, 1960], No. 19034/60. Class 39 (1). A gas-filled electric discharge tube incorporates a hollow waveguide 1 and a cathode 12 and an anode 15 at opposite ends of the guide. An electric discharge is established between the cathode and anode in a longitudinal magnetic field of such strength that the guide is filled with a plasma of a density enabling the guide to propagate space change waves with a phase velocity considerably less than the velocity of light at a frequency below the normal cut-off frequency of the guide in the absence of plasma. The tube shown is a travelling wave amplifier tube in which a space charge wave travelling along the guide interacts with an electron beam generated by the gun 23, 24, 25 and collected by the cathode 12. The signal connectors are shown at 2 and 3 and forward wave interaction is used. One connector may be omitted to provide a backward wave oscillator tube. The cathode 12 is an indirectly-heated thermionic emitter, the emissive portion being formed by a porous block 13 of sintered tungsten impregnated with alkaline earth metal compounds. The anode 15 is formed by two discs 16, 17 brazed to a water cooling loop 20. The waveguide 1 forming part of the tube envelope is encircled by a water cooling pipe 7. The waveguide may be within the envelope and not part of it. The gas filling is hydrogen or, according to the Provisional Specification, krypton, at a pressure of 10<SP>-2</SP> mm. Hg. The envelope sleeve 9, the bulb 11 and the various elements associated with the bulb 11 may be omitted to provide a delay device, a plain disc being fitted across the end of the waveguide to serve as an anode for the discharge.

Title: Improvements relating to multi-color lithographic printing forme method of preparing same and method of use
IPC: B41C1/10
Filed: 1966-05-03
Abstract: 1,114,365. Printing processes &c. DURIRON CO. Inc. 3 May, 1966 [10 May, 1965], No. 19564/66. Heading B6C. In a two-colour lithographic offset printing process an oil-based ink and a water-based ink of a different colour are applied consecutively to a specially prepared forme. The latter is preferably of polytetrafluoroethylene which has been so treated that one surface portion is repellent to both inks, a second surface portion is receptive to both inks whilst a third surface portion is selectively receptive to one of the inks only. The apparatus shown in connection with the process is a rotary offset press in which the plate cylinder receives ink from two roller trains each of which supplies an ink of a different colour and base. In the preparation of the described plate one face of a sheet of polytetrafluoroethylene is chemically or electrically etched prior to coating with a resist of a light-sensitive albumen. The etched surface is receptive to both oil and water-based inks. The coating is contacted by a negative with a translucent or transparent area of the required shape before subjection to a light source. The unexposed resist is then washed off leaving an area of waterinsoluble exposed resist corresponding to the translucent or transparent area which is receptive to oil-based ink but repellent to waterbased ink. A second negative having ultraviolet opaque areas-one corresponding to the translucent or transparent area of the first negative-is next applied to the surface, whereupon it is subjected to an ultra-violet light source. This destroys the etching in those areas beneath the second negative not covered by the opaque areas such that the previously etched surface is smoothed and made repellent to both ink forms. Thus a plate is produced having three forms of surface one, 18, Fig. 6, receptive to oil-based ink but repellent to water, one, 14a (etched), receptive to both ink forms and one, 14 (smooth), repellent to both such forms.
