Filed: 1971-06-18
Abstract: 1313251 Ground effect machine docking TEXACO DEVELOPMENT CORP 18 June 1971 [2 July 1970] 28615/71 Heading B7K An hydraulic lift device for transferring a ground effect craft 23 between upper and lower levels, includes an upright chamber 16 to give the craft 23 access thereto at the upper level, means 14a for giving the craft access to the chamber at the lower level, and an hydraulic system 32 communicating with the chamber 16 for regulating the level of liquid in the chamber. In operation a ground effect craft 32 supported on a cushion of air on the surface of a tidal body of water enters the chamber when a pair of gates 14a (14b, Fig. 1, not shown) are open and the level of water in the chamber defines the lower level. When the tide is abnormally low (i.e. below a ramp 22) the craft enters the chamber on the ramp 22. The gates close and water from a reservoir 31 enters the chamber 16 through the hydraulic system 32 and a hollow sump 21 forming part of a foundation 18, the sump having bores through which the water escapes therefrom into the chamber. The craft, still supported by its cushion of air rises with the water in the chamber until it is at the upper level flush with a ramp 17 over which it may move under its own power. Guide rails 34 and 36 are provided for stabilizing the craft at the upper level. The chamber may be provided with an internal surface of the same shape as the craft to guide the craft within the chamber, Fig. 5 (not shown).

Title: Roll wrapping machine
IPC: B65B25/14
Filed: 1962-07-25
Abstract: 961,790. Wrapping-machines. ALLISCHALMERS MANUFACTURING CO. July 25, 1962 [Aug. 2, 1961], No. 28644/62. Heading B8C. A machine for crimp folding down the projecting tubular ends of a wrapper enclosing a roll includes sensing means which position the crimping elements according to the dimensions of the roll. The roll 69, surrounded by a wrapper which is supplied and gummed by apparatus not described, is supported and rotated by rollers 24. The crimping elements 19, 20 are movable axially on and are rotated by a shaft 11 supported on pivoted arms 12. The arms are lowered by pneumatic means 14 until a sensing arm 58 contacts the roll and operates a switch to stop the descent. Pneumatic means 50 then slides the element 19 into contact with the roll and a lead screw 54 is rotated to advance the element 20 towards the roll until halted by a sensing arm 60. The roll and elements 19, 20 rotate to produce folding. The elements 19, 20 may comprise freelyrotatable rollers 42 with or without flat plates 43 between them. Each roller may be replaced by three on the same axis or may have a tapered form 66 to reduce velocity differences between the rollers and the wrapping material.

Title: Writing head
IPC: H01J17/49
Filed: 1975-07-08
Abstract: 1484785 Gas discharge apparatus E LE COQUIL J C AMICEL J P MARTINIERE 8 July 1975 [8 July 1974] 28670/75 Heading H1D A writing head for reproducing a line of an image on a light-sensitive surface comprises, in contact with a gas at low pressure, a series of cathodes K 1 , K 2  &c. and two parallel, adjacent metallic strip anodes 25, 26, one of which 25 is opaque and continuous and the other of which 26 is provided with a series of holes in correspondence with the respective individual cathodes so that light produced by the gas discharge can be selectively allowed to pass through the holes on to a photo-sensitive carrier. As shown, the cathodes K 1 , K 2  &c. on substrate 20 are parallel, extend transversely of the anodes and are connected cyclically to four bus-bars A, B, C, D, the arrangement being such that by sequentially pulsing the bus-bars a glow discharge is effected between a respective anode and each of the cathodes in turn. The discharge is initiated by starting electrode T which causes sufficiently localized pre-ionization that when a pulse is applied to bus-bar A the discharge transfers only to adjacent cathode K 1 , the other cathodes K 5 , K 9  &c. connected to bus-bar A being too far away to be affected by the pre-ionization. By switching the discharge between the anodes 25, 26 in accordance with an information signal representative of the image to be reproduced, a point light output is only obtained when the discharge is to the perforated anode 26. Furthermore the intensity of the luminous points may be modulated, e.g. by controlling the period or strength of the discharge current, so that documents that require helf-tones may be reproduced.

Title: Electrical onload tap changing systems
IPC: H01F29/04
Filed: 1972-06-20
Abstract: 1399528 Transformer tap-changing arrangements A I KRASOV 20 June 1972 28814/72 Heading HIT An on-load tap changer comprises at least four switching members, load switching means 7, a selector switch 34 having at least two movable contacts 6 and 8, and a resistor 5 for limiting the current appearing at the switchover. In the static state the load current I h  flows through main contacts 1 and 8 while auxiliary contacts 2, 3, 4 and 6 have no current flowing through them. To change from tapping 9 to tapping 28 the following sequence occurs. Shaft 11 is rotated by actuator 10 to close contacts 3 and 2 and 19 and 20. In this position all contacts are closed and current can also flow through thyristors 15 and 16. Further rotation breaks contacts 1 and 4, and the load current is then carried by the thyristors until contacts 19 and 20 open and turn them off. Current must now flow through contact 3, resistor 5 and contact 6, and no current flows through contact 8 which may be moved to the tapping 28 by means of shaft 26 turned by Geneva cross 24. This shifting does not turn the contact 8, connected to shaft 27, because of the coupling 23 which ensures that the turning of Geneva cross 25 lays behind that of cross 24. Contacts 1 and 4 and 19 and 20 now make and the load current flows again in contact 8 and through tapping 28. There is current flowing between tappings 28 and 9 due to the voltage existing across this stage. This current is limited to not more than I h  by the value of resistor 5. Contacts 2 and 3 break and the current passes through thyristor 15 and 16 until contacts 19 and 20 break. Contact 6 is now dead and is moved to tapping 28 by Geneva cross 25 to complete the switching operation.

Title: Apparatus for checking curved surfaces
IPC: G01B5/20
Filed: 1945-10-31
Abstract: 627,970. Surface and outline gauges. NEWTON, E. P. (Gear Grinding Machine Co.). Oct. 31, 1945, No. 28943. [Class 106 (ii)] In apparatus for checking cycloidal-section surfaces of conjugate members by means of a dial-gauge which traces the -surface, a pair of parallel shafts, spaced at a distance equal to that by which the conjugate members are normally spaced, are connected by gearing of the same ratio as that of the conjugate members and are adapted to carry the male and female members respectively, the members being tested separately and the dial gauge being mounted on the shaft not carrying the member under test. To test the cycloidal curves of the male member A, Fig. 1, of a compressor pump, the member is clamped to a shaft E which is mounted in bearings parallel to a second shaft El. The shafts are connected by gears F, F<SP>1</SP> which correspond to the pitch circles of the male and female pump members respectively. A support H is mounted on a reduced extension of the second shaft E<SP>1</SP>, to which it is clamped by means of a screw H<SP>1</SP>, and carries a dial-gauge J mounted on an arm so that the feeler of the dialgauge may be set at a distance from the axis of the second shaft E<SP>1</SP> equal to the radius of the pitch circle of the gear F<SP>1</SP>. On rotation of the shafts, the feeler of the dial-gauge will thus trace out the cycloidal curve of the surface of the male member and any errors therein will be indicated by the gauge. To test the cycloidal curves of the female member B, Fig. 5, it is mounted on the shaft E<SP>1</SP>, and the dial-gauge is adjustably mounted on an arm carried by a head L secured to a plate K at a distance from the shaft E, on which the plate is mounted, equal to the radius of the pitch circle of the gear F. Arcuate curves on the male member A may be tested by mounting the member and the plate K on the shaft E, Fig. 6, and by rotating the head L so that the feeler of the gauge carried thereby traces out the required arc. In the case of the female member, the arrangement for testing arcuate curves is as shown in Fig. 5, but the head L, carrying the gauge, only is rotated. Sleeves (not shown) may be mounted on the shafts E, E<SP>1</SP> in place of a test-piece to facilitate accurate setting of the dial-gauge feeler.

Title: Improvements relating to materials for rendering sea water potable
IPC: B01J39/02
Filed: 1950-11-29
Abstract: A silver cation-exchange resin for use, e.g., as a disrupting agent in, or principal ingredient of, a briquette for rendering sea-water potable (see Group I) is prepared by sulphonating a copolymer of styrene and divinyl benzene, crushing the product, and converting it to the silverexchanging condition by soaking in silver nitrate solution, rinsing and drying.  Specifications 571,029, 577,449, [Group I], 577,707, and 605,174, [Group III], are referred to.ALSO:A silver cation-exchange copolymer of a mono-vinyl aryl compound and a di-vinyl aryl compound is used, preferably as a disrupting agent, in a briquette suitable for use in rendering sea-water potable by silver cation-exchange.  The silver cation-exchange resin may be regarded as part of the exchange material forming the principal ingredient of the briquette, the other part of the exchange material consisting preferably of a silver alumino-silicate preferably prepared as described in Specification 605,174, [Group III].  The silver cation-exchange resin may constitute from 0.5 to 70 per cent by weight of the briquette, but preferably 1 to 10 per cent; between these narrower limits it acts primarily as the disrupting agent having a lower exchange capacity than the silver alumino-silicate. The resin may be a copolymer of styrene and divinyl benzene of the kind described in Specifications 571,029 and 577,707 is preferably a sulphonated copolymer of this kind, and is converted to the silver-exchanging condition by soaking in silver nitrate solution, rinsing and drying.  It is preferably ground to a size such that it will pass through a U.S. standard 100-mesh sieve.  A briquette having a total weight of 68.1 grams had the following composition: silver cation-exchange resin 1.3 grams, silver alumino-silicate 62.3 g., stearic acid (briquetting lubricant) 0.8 g; activated carbon 0.2 g., barium hydrate 3.5 g.  All the ingredients were mixed dry and compressed under a pressure of between 12 and 16 tons per square inch to form a briquette about 3.0 cubic inches in volume.  The "disruption time" and "filter time" of the briquette are less and the ion exchange capacity of the values for briquettes using bentonite or Fuller's earth as a disruption agent.  Specification 577,449 also is referred to.

Title: Improvements in or relating to paper and like sheet separating devices
Inventor: BLOCK ALFRED ERNEST
IPC: B65H3/34
Filed: 1958-09-12
Abstract: 932,551. Feeding sheets. BLOCK & ANDERSON Ltd. Sept. 11, 1959 [Sept. 12, 1958], No. 29291/58. Class 100 (1). Sheet-separators.-In apparatus for separating sheets sequentially from the top of a pile 10 by friction rollers 12 or other means, the separation of two sheets together is prevented by a clamping finger 14 which normally exerts a downward pressure on the pile, this pressure being relieved periodically to enable a friction roller 17 to withdraw the uppermost sheet from beneath the finger so that it can be fed from the pile by the rollers 12 or other means. There are two separator rollers 12 which rest on the pile 10 and are driven intermittently by a chain or belt drive, and the pile is supported on a table 11 which can be raised manually or automatically as the pile is depleted. An adjustable block 13 has pivoted thereto at 28 the clamping finger 14 which terminates in a thin blade and has a cam-shaped upper surface 21. The friction roller 17 is connected to a fixed shaft 33 through a one-way clutch for rotation only in the counterclockwise direction, this shaft being supported in arms 16 which are connected to arms 15 pivoted to the block 13 at 32. The arms 15 can be oscillated through a rod 22 from the associated machine, whereupon the arms 16 and roller 17 are reciprocated across the top of the pile. One arm 16 has a depending lug 19 carrying a roller 20 which runs along the cam surface 21 of the clamping finger 14. In operation, as the arms 16 and roller 17 are moved forwardly over the pile, the roller 17 is clear of the pile at first and the weight of the arms and roller 17 is carried by the finger 14; when the roller 20 clears the finger 14, the friction roller engages the top sheet, pulls it from beneath the finger, and, in co-operation with the separator roller 12, buckles the sheet at B. The arms 16 and roller 17 now return to exert clamping pressure onthe finger 14, the top sheet straightens out to overlie the finger 14, and the separator roller 12 is driven to feed the top sheet from the pile. In modifications, the clamping finger 14 can be arranged over a side edge or a corner of the pile, in which cases the buckling of the top sheet is effected by the roller 17 and a side lay on the table 11 which projects upwardly beyond the top of the pile.
