Title: Improvements in or relating to the loading or unloading of ship's holds
Inventor: ELDERFIELD STANLEY CHARLES
IPC: B63B27/22
Filed: 1969-02-11
Abstract: 1,248,991. Loading ships; endless belt conveyers. FLEXIBLE CONVEYER CO. Ltd. 11 Feb., 1970 [11 Feb., 1969], No. 7278/69. Headings B8A and B8E. To load articles such as bagged products into a ship's hold through a hatch 4, a vertical flexible elevator 38, 39 extends into the hold and receives articles from a de-palletizing unit 12 via conveyers 24, 29, 43 for delivery to a turn-table 44 and discharge conveyers 48, 49. The frame 36 of the flexible elevator is supported by drivable rollers 35 in a support frame 34 so that it can be raised and lowered to adjust the height at which the telescopic conveyers 48, 49 deliver the articles. The elevator comprises an endless band conveyer 38 co-operating with a series of band conveyers 39, some at least of which can be swung outwards by rams 37 acting on frames 40 so as to provide an entry point adjacent the conveyer 43 at whatever height the frame 36 is positioned. To load a hold pallets 14 are moved from a table 13 to a tilting lift table 16 which is tilted and raised until bags 15 successively slide over a roller 22 on to the conveyer 24 from which they are fed by conveyers 29, 43 to an outwardly adjusted entry conveyer 39 and thence by the flexible elevator through a shoot 45 to the turntable 44 from which they are diverted by a belt 50 to the delivery belts 48, 49, which can be moved about a pivot 46 to direct the bags to the desired point in the hold. As the hold fills the frame 36 may be raised to deliver the bags at a greater height using lower entry conveyers 39 in turn. By suitable adjustments the conveyers may be reversed to use the arrangement for unloading a hold. The elevator is mounted on a gantry comprising side frames 9 and beams 10 and the gantry runs by wheels on rails at either side of the hatch 4. The wheels may be adjusted heightwise to level the beams 10 and to ensure that the elevator is vertical.

Title: Improvements relating to self twilling jacquard machines for looms
IPC: D03C3/24
Filed: 1927-03-16
Abstract: 286,467. Douglas, S. W., Gregg, J., and Silcock, M. March 16, 1927. Jacquards.-Self-twilling jacquards of the Bessbrook type have the usual twilling bars 1 operated by pegs on a barrel on a shaft 11 and furnished with notches to turn the griffe blades 3 from an inclined to a vertical position, whereby these blades are moved from the position in which, when raised, they engage the ordinary hooks 4, so that consequently whole rows of these ordinary hooks are left down as required to produce twilling in the pattern. In addition, however, separate and independent secondary twilling bars 7 are operated by tappets 8 on tappet barrels 9 driven from the shaft 11 of the ordinary tappet barrel, whereby particular ones 6<a> of twilling bars 6 which are separate from but are raised and lowered with the blades 3 may be moved from an inclined to a vertical position so as to engage particular ones 5<a> of the twilling hooks 5. These hooks 5 are attached to bars' 13 embracing closed loops 14 in the ordinary hooks, so that the raised twilling hooks 5<a> cause whole rows of ordinary hooks to be raised to produce twilling in the ground in any order. Thus whilst the twill in the pattern runs from right to left, the twill in the ground may be arranged to run from left to right or vice versa and may start at any twilling hook. Both the primary and secondary twilling bars may be spring controlled.

Title: Improvements in or relating to devices for operating hinged or pivoted windows and the like
IPC: E05F11/06
Filed: 1947-03-18
Abstract: 623,599. Window regulators. CRAGGS, J. W. March 18, 1947, No. 7393. [Class 20(iii)] [Also in Group XXXI] Pivoted windows and the like are opened and closed from a remote position by a cable which slides to and fro in a sheath, being unwound from or wound onto the grooved rim of a wheel or ring-like member. The apparatus comprises a cable, consisting of a core J with a wire cover K, attached at one end by plate W to the window sash and operating through tubing E, which leads the other end of the cable into a housing A, mounted at the remote position. In the housing the cable is carried around a groove in the rim of a ring G, being secured to the ring at M. Internally the ring has teeth which are engaged by a cog wheel, N, to the shaft of which is secured a handle R. Thus a clockwise rotation of R causes the ring G to rotate and the cable to slide out through tube E to open the window, the fully open position being reached when stop H contacts the cog N. A locking device is provided on the handle so that the window may be set at any position. Specification 293,915, [Class 80(iii)], is referred to.
Patent GB-772255-A (GB)
Title: An improved governing system for gas turbine plant
Inventor: CHAPPELL HERBERT EDGAR
Filed: 1954-03-15
Abstract: 772,255. Gas turbine plant. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. March 3, 1955 [March 15, 1954], No. 7500/54. Class 110 (3). [Also in Group XXIX] A gas turbine plant comprises an output turbine 1, a heating system supplying working fluid to the turbine and supplied with air from an independently rotated turbine driven compressor 3, a valve 8 controlling the fuel supply of the heating system closed by excess speed of the turbine 1, and a blow-off valve 15 on the outlet side of the compressor opened by excess speed of the turbine 1 and thereafter closed by decrease in speed of that turbine or by decrease in compressor speed or pressure. The heating system includes a heat-exchanger 5 heated by exhaust from the turbine 1, and a combustion system 2 supplied with fuel from a source 6, the hot gases from the combustion system driving the turbine 4 driving the compressor and the exhaust from the turbine 4 forming the working fluid for the turbine 1. The blow-off valve is a double beat valve having a valve member 14, and is connected by a line 16 to a header on the heat-exchanger. The valve member is biased on its seats by a spring 32, and has a stem 14a extending into a chamber 18, the extension of the stem being enclosed by a metal bellows 20, the interior of which is supplied with air from the line 16. The chamber 18 is connected by a line to the pressure source 12 of a servosystem controlling the valve 8, a change-over valve 24 having a connection to a low pressure source 28 being interposed in the line. When the turbine 1 rotates at ordinary speeds, pressure fluid from the source 12 keeps the valve 8 open, and keeps the ball 27 of the valve 24 on the seat 26 so that the pressure of fluid in the chamber 18 is greater than that within the bellows and the valve 15 is closed. When the turbine 1 rotates at excess speeds a governor 9 cuts off the source 12 from the valve 8 and the chamber 18 so that the valve 8 closes to shut off the fuel supply to the combustion system and the low pressure source is connected to the chamber 18. The pressure of the low pressure source is greater than the pressure from the compressor at a predetermined speed so that should the compressor speed fall below the predetermined speed the blow-off valve closes. The valve 24 should be sluggish in action and the ball may be replaced by a piston. If the heat-exchanger is of annular form more than one blow-off valve may be arranged in a ring around the heat-exchanger.

Title: Improvements in Printing Woven Fabrics.
Inventor: ROBERTSON ROBERT
IPC: B41F17/00
Filed: 1918-05-06
Abstract: 125,251. Robertson, R. May 6, 1918. Printing processes; embossing.-Relates to a method of printing fabrics with designs having the appearance of being woven into the fabric. The design is impressed on to the fabric by one or more ordinary intaglio printing-rollers with or without colour, in an ordinary calico-printing machine, and the fabric is then passed over the surface of an ordinary rubbing roller, which consists of a roller engraved with fine lines or cross lines and set out of contact with the impression bowl and driven at a different surface speed from that of the material. The intaglio roller leaves a fa.int impression of the design on the fabric by flattening the surface in some parts more than in others so that, in the subsequent rubbing, the colour is taken up in varying amounts at different parts of the surface of the fabric, and the pattern shows up in a more or less shadowy form.

Title: Improvements in and relating to apparatus for the detection of vehicles contraveningtraffic regulations
IPC: G08G1/017
Filed: 1959-03-04
Abstract: 910,526. Photographic recording of movements of selected road vehicles. AGFA A.G. March 4, 1959 [March 4, 1958], No. 7586/59. Class 98 (1). [Also in Groups XXXVIII and XL (c)] Relates to apparatus comprising means for detecting that a vehicle is contravening a traffic regulation, and means for operating a camera 8 to make a plurality of photographs in a predetermined time relationship. A road pad 7 is so positioned that a vehicle contravening a regulation, such as passing a stop light 4, or crossing on to the wrong side of the road, passes over it closing a contact which controls the shutters of a camera and also starts a timer (see Group XL (c)) which operates the shutter again at the end of a predetermined time interval. For detecting excessive speeds, two spaced road pads are employed, photographs being taken only if the time interval between passing them is less than a predetermined minimum. A modified timer (see Group XL (c)) is used having two timing circuits, one, as before, for the camera and the other for the permitted time to pass between pads. The camera 8, flash light 9 and timer 10 are all mounted in a case at the roadside.

Title: Improvements in and relating to computers
IPC: G06G5/00
Filed: 1957-03-07
Abstract: 832,704. Calculating-apparatus; indicating- apparatus. SVENSKA AEROPLAN A.B. March 7, 1957 [March 7, 1956], No. 7603/57. Classes 106 (1) and 106 (4). Calculating-apparatus, which may form part of an indicating device, comprises three or more links pivoted together at their ends to form a triangle or other polygon, one of the links being extensible, and the figure, which is constrained by guide members respectively connecting the pivots to setting members movable along arcuate paths, assumes a neutral position when variables represented by the positions of the setting members are in a predetermined relationship to one another. In one form, Fig. 1, the extensible link 8 is formed by a spring and two other links 7a, 7b are formed by threads. Rings, e.g. 6a, form the pivots between the links and are connected by threads 5a to setting slides 50 movable along arcuate guides 2a and indicating against scales 4a. In the neutral position of the Figure, the rings 6a are directly over the centres, e.g. A, of the respective arcuate guides 2a and it is shown that the scales 4a may be so graduated that the variables x, y and z indicated thereby are such that xyz=1. The scales may be calibrated to provide other relationships, e.g. x=yz. In another form, Fig. 3, two rigid links 16a, 16b and a link incorporating a spring 18 are pivoted together and to guide arms 13a, 13b, 13c, pivoted at their opposite ends to setting members 12a, 12b, 12c, carried by arms pivoted on shafts 11a, 11b, lie in a frame 10. The arms carrying the members 12b, 12c are positioned automatically by pressure-sensitive devices 32, 33 acting through gears 29b, 29c bearing indicating scales and cams 27b, 27c. The third member 12a is actuated, by means of a cam 27a and gear 29a driven by a reversible electric motor 31, so as to move the figure into the neutral position. This is achieved by providing the arm carrying the member 12a with contacts 21a, 21b between which moves a contact 23 carried by the arm 13a. The motor drives in one direction or the other according to whether the contact 23 engages the contact 21a or the contact 21b. A fixed pointer 35a indicates on a scale carried by the gear 29a the ratio between the two pressures. A further manuallyset device, Fig. 5, has four links supported similarly to the links in the embodiment shown in Fig. 3. The neutral position is indicated in this case by contacts 54, 55 movable with the setting member 14a and co-operating with a contact 23 carried by the arm 13a so as to control lights 42a, 42b.
