Title: Improved safety stop for travelling structures
IPC: B66C9/18
Filed: 1925-09-29
Abstract: 252,599. Wellman Smith Owen Engineering Corporation, Ltd., (Case, A. F.). Sept. 29, 1925. Skid ; locking by friction detents. - Relates to safety skid brakes for structures travelling along rails and particularly travelling bridges, in which a body member suspended from the structure by links has a part formed to constitute a wheel blocking wedge and carries a clamp for frictionally engaging the rail. The invention mainly consists in the operation cf the brake by a counterbalanced arm which, on release of a lever holding the brake in the inoperative position, acts by gravity in conjunction with the. suspension links to move the body member and clamp into engagement with the wheel and rail. The body member 14 suspended from the structure 13 by inclined links 37, 38 is formed with a wedge portion 16 and rail guides 15 and carries levers 17 pivoted thereto at 18 and formed with clamping jaws 18<a> for engagement with the rail. The levers 17 are connected by links 19 to arms 20 which are adapted to be rotated by pinions 23 engaged by a toothed segment 24 carried by the operating arm 25. The arm 25 is pivoted to the member 14 at 26 and is extended at 28 to support a motor which serves also as a counterweight, the arm also carrying a pin 45 engaging a slot 44 ona link 43. The brake is held in the inoperative position, shown in Fig. 3, by a lever 33 pivoted on the arm 25 and carrying a roller 34 which engages a recess 36 in a surface 35 on the body member, the pin 45 being held against the lower end of the slot 44. When the motor 29 is rotated in one direction, the lever 33 is turned in the clockwise direction and permits the arm 25 to rotate in the counter-clockwise direction. The pin 45 is then disengaged from the lower end of the slot 44 and the bodv member 14 moves under gravity towards the wheel and rail, the jaws 18a being simultaneously moved to grip the rail by means of the pinions 23 and segment 24. The motor is then stopped by an automatic switch. Rotation of the motor 29 in the opposite direction returns the parts to the position shown in Fig. 3, the roller 34 on the lifting arm 33 running up the surface. 35 until it reaches the recess 36 when the motor is again stopped by a switch. A number of such brakes may be applied to each wheeled support of a travelling bridge, the motors being controlled from a single point, preferably the operator's station on the bridge proper.

Title: Improvements in or relating to rolling
Inventor: DOWNS EDWARD ALAN
IPC: B21B37/16
Filed: 1964-06-11
Abstract: 1,091,484. Automatic control of rolling mills. BRITISH IRON & STEEL RESEARCH ASSOCIATION. June 4, 1965 [June 11, 1964], No.24255/64. Heading G3R. To control thickness of material rolled in a reversing mill, e.g. for hot plate finishing, measurements are made of ingoing thickness, width and temperature and corresponding signals fed to a digital computer with other signals chosen manually or by punched card to correspond to pass characteristics, such as speed and draft, and mill characteristics, such as deformed roll radius. The computer operates according to formulae given in the spec. to predict the necessary load on the mill rolls which it then produces by control of the roll screw-down motors. During the first pass the computer compares the actual roll load, as determined by strain gauges, with that predicted, and any error is caused to alter the gain of the control system so that more accurate prediction is made for the next pass which, being in the reverse direction, utilizes measurements of thickness, width and temperature on the other side of the rolls. The signals representing mill characteristics, which are determined by trial passes, are revised periodically, e.g. for each working shift.

Title: Method and apparatus for binding books, catalogues and the like
IPC: B42C9/00
Filed: 1960-07-13
Abstract: 934,823. Bookbinding. J. HUNKELER. July 13, 1960, No. 24399/60. Class 16. A method of binding books, catalogues, and the like, is characterized in that a book filler is coated with adhesive along its spine and on both sides of the filler along a longitudinal strip of each of the outermost sheets of the filler, the strips adjoining the spine whereby the adhesive substance forms a resilient tough connected film between the spine and sides of the filler after setting. The filler is then trimmed and the outermost sheets fastened on a book cover without the use of a gauze strip, so that the longitudinal strips of adhesive bear directly against the inside of the cover. In a machine for applying the adhesive, the fillers are fed back downwards along a guide adjustable in height, to an endless belt conveyer 2. The fillers are conveyed between frusto-conical discs 6 applying adhesive to the sides of the filler adjacent the spine and past one or more cylindrical rollers mounted with their axes horizontal, for applying adhesive to the spines of the fillers. The adhesive substance is a synthetic material of polyvinyl acetate dispersion basis, and may be applied by spraying nozzles or spreader blades. The tanks containing the adhesive in which the rollers and discs rotate, are adjustable in height by rack and pinion movements and the rollers by a cam arrangement. The spacing between discs 6 and rollers 10, pressing the endless belts 2 into engagement with the books, is adjustable for different widths of books. Additional coating means such as brushes may be provided, and the fillers may pass to a second conveyer whereby the adhesive is dried by infra-red heaters, lamps, or highfrequency heating. A doubled sheet of paper comprising an end sheet may be secured at each side of the filler by a longitudinal strip of adhesive.

Title: Information selecting and displaying apparatus
IPC: H04N7/00
Filed: 1971-04-19
Abstract: 1341763 Educational television systems HITACHI Ltd 19 April 1971 [24 March 1970] 24567/71 Heading H4F An educational T.V. system includes means for indicating which of a series of repeatedly sequentially transmitted imagesisto bedisplayed, means for selecting the transmitted signal. corresponding to the indicated image and means for displaying this image. The signals of the series may comprise video signals with each image represented by one field or one frame, or digital signals representing the type, size and position of characters and symbols to be displayed. In the latter case the receiving part of the system includes circuity for generating the required characters and symbols in response to the transmitted digital signals. Figs 1 and 2 show a general view of a system used to receive a series of broadcast T.V. signals corresponding to the images of the series. The series is preceded by a "start" signal, and a counter 21 (Fig. 2) forming part of indicator 5 (Fig. 1) counts synchronizing signals preceding the signal for each separate item of display information. A key unit 24 permits a particular image of the series to be selected by inserting a corresponding number into register 23 and comparing this in comparator 22 with the output of the counter 21. When the desired image is reached the comparator 22 causes gate 25 to be opened, allowing the selected image signal to pass to a memory 6; e.g. a delay line, magnetic disc or drum or video tape recorder; from which it is transmitted repeatedly to the display tube 3. If a persistent-image tube is used the memory 6 may be dispensed with. Fig. 4 illustrates a more complex modification of the circuit parts shown in Fig. 2. In this modification the first image of the series includes a question to which alternative answers are provided. The viewer depresses one of three keys on an answering unit 44 in order to express his answer, and this opens one of the gates 48-50 in order to extract a corresponding piece of information from register 43. The register 43 stores three pieces of information which determine three alternatives for the next image to be displayed, the signals carrying these pieces of information having been included with the first image signal and having been separated therefrom in a separator 42. Dependent upon the viewer's answer, a signal indicating which of the other images in the series is next to be displayed is stored in register 45 and is compared at 46 with the output of a counter 41 counting the synchronizing pulses preceding each image signal. When the desired second image signal is reached a gate 47 is opened and the image signal proceeds to the display device, the associated signals indicating the alternatives for the next image once again being separated off and stored in register 43 to allow the same procedure to be repeated.

Title: Improvements in or relating to cameras
IPC: G03B19/18
Filed: 1936-09-09
Abstract: 483,820. Lens mounts ; colour photography. HILLMAN, A. G., and JOHNSON, G. H. Sept. 9, 1936, No. 24614. [Classes 97 (i), 98 (i), and 98 (ii)] A screw-operated focusing mount for a kinematographic or photographic camera of the kind in which the screw surfaces encircle the objective comprises a plurality of objectives in a screw threaded mount which is axially displaceable by a co-operating screw-member for simultaneously focusing the objectives and fine adjusting means for partially rotating the mount about the axis of its screw surface so as to turn one or more of the objectives bodily about such axis for controlling the arrangement of the images cast by the objectives on the image-receiving surface, the means serving to restrain the mount against rotation whilst it is being moved axially during focusing. As shown, the mount 4, carrying three lenses 1, 2, 3, has an external thread 5 engaged by a rotatable axially restrained nut 6. Projecting from the mount is a spring arm 7 carrying a pin 8 engaged by screws 10, 11, adjustment of which rotates the mount to bring the centres of the lenses 1 and 2, fixed in the mount, into vertical relationship. The lens 3 is mounted in a laterally elongated aperture, and by loosening the holding screws 15 and slackening one of the screws 10, 11, the mount can be rotated by the arm 7. A stop against the lens 3 causes the lens to move laterally on rotation of the mount, and permits its adjustment into vertical alignment with the other lenses. The elasticity of the arm 7 permits axial movement of the mount for focusing. Alternatively a slide-guided rigid arm 7 may be used. The nut 6 may be provided with a pointer 22 co-operating with a scale. The adjustment of the lens 3 may be effected by screw means. The lenses may be independently focused by the use of opposing screws allowing the lenses to be moved axially in either direction. A camera incorporating the lens mount may be used to produce a series of colour component negatives on a single film, and from this film a positive for projection through colour filters can be printed, or colour component matrix films for imbibition printing may be printed therefrom. The camera may also be used to produce black and white films. Specification 483,817 is referred to.

Abstract: 429,458. Jigging - conveyers. ILLINGWORTH CARBONIZATION CO., Ltd., 16, Kennedy Street, Manchester, and ILLINGWORTH, S. R., Fernwood, Radyr, Glamorgan. Nov. 30, 1933, Nos. 24680/34 (Divided application and 23812/34. [Class 78 (i)] [See also Groups XII and XIII] In the carbonization or drying of coal or like carbonaceous material, or of briquettes made therefrom, the material is conveyed through a retort on a surface or tray mounted for lengthwise to and fro movement, the surface being displaced in one direction and its return movement being sharply arrested so as to cause the material to be fed along it. Sealing means enclose the upper side of the surface to form a closed heating chamber, and the actuating and supporting means for the retort are arranged externally of the sealing means. The charge is delivered on to one or more trays, each tray being reciprocated by a pusher rod 23 and cam 35. A collar 33 on each rod contacts with a buffer 24 imparting a sudden jar to the tray which causes the material to be shifted along to the discharge end from which it falls into a sump 52 to be discharged by rotary means 54. The distillates escape by an outlet 56. If drying only is required the hot gases pass into contact with the trays. In one modification, Fig. 3, the tray is built up of corrugated plates 65 supported by bars 67, 68 secured to cross members 70 attached to transverse guides 78 by arms 75 pivoted at 76 and 77. The top of the tray is closed by cover plates 72 attached to the cross members 70 and to four depending flanges, two, 73, of which are shown, dipping into a water seal 63, so that the supporting arms operate in a cool atmosphere. In Fig. 9, the water seal is divided into a number of separate seals, the tray 65 being slung by stirrups 105 from angle irons 104 secured by vertical posts 103 to guides 102 having inverted cups 108 dipping into annular cups 109 containing water. The trays and supporting structure are swung from arms 75, the dimensions of the water seals accommodating the movement. The oven chamber has an arched roof 112 and is recessed to receive heating flues 113 which are spaced apart to increase the heating surface. The heating system may be according to that described in Specification 350,960, [Group XII], and a discharge feed as described in Specification 276,604, [Class 59], may be used. The briquettes employed may be made as described in Specification 212,663, [Class 55 (ii)]. Specification 235,627, [Class 34 (ii)], also is referred to. The first Provisional Specification describes also heating means of the kind above referred to but without liquid or similar sealing means.

Filed: 1949-09-26
Abstract: 686,177. Jib cranes. RANSOMES & RAPIER, Ltd., and STOKES, A. S. Sept. 15, 1950. [Sept. 26, 1949] No. 24697/49. Class 78 (iv). Luffing. A single luffing rope 24 controls the movements of the jib 12 about its heel pivot 14 and of an extension 16 about a hinge 18 on the jib. The rope 24 passes from a drum 50, around pairs of pulleys on the shaft 48 and on a shaft 46 carried by the jib 12, and around pulleys on shafts 26 and 32 carried respectively by the jib 12 and by the extension 16 and is dead-ended to the shaft 26. Inward luffing movement of the jib 12 is limited by a stop 52. The balance of the system is such that the jib 12 is held on its stop 52 while the extension is lowered from its uppermost position as shown in full lines in Fig. 2 to the broken line position. The jib and extension are then connected for movement together by engagement of a cross-bar 58 secured to guys 54 on the extension with the end of slots 60 on the jib. When the extension has reached the horizontal it is restrained against further downward rotation by engagement of a further cross bar 84, carried by guys 82 on the extension, with a fixed stop 86: the main jib may be further lowered with the extension horizontal. The relative movement of the extension 16 and the jib 12 may be prevented or reduced by a catch 80 which may be moved to obstruct the movement of the cross-bar 58 in the slot 60. The extension may, as an alternative to the arrangement shown, move with the jib during the initial derricking out and alone subsequently. Balancing. To compensate for the variation in the ratio of the forces required to support the extension and the main jib under varying loads, the hoisting rope 62 is led from the winch 64 over guide pulleys 66 and 67, Fig. 3, around a pulley 68 on the shaft 32 near the heel of the extension, around a pulley 70 on the shaft 26 carried by the main jib and over a further pulley 72 on the shaft 32 to the jib-end pulley at the end of the extension. Specification 470,295 is referred to.
