Title: Improvements in loose-leaf binders
IPC: B42F13/20
Filed: 1958-05-07
Abstract: 837,875. Filing papers. BURN & CO. Ltd., J. May 7, 1958 [May 8, 1957; Aug. 2, 1957], No. 14645/58. Class 146(1) A binding element for a loose-leaf ring binder has pairs of one-piece half-rings which in closed position overlap each other, and are in surface contact with each other, and a pair of spine-forming members which when the element is closed provide it with a substantially flat back, the half rings in each pair being directly hinged to each other and all the rings on one side of the element being connected together by one of the two spine-forming members, the spine-forming members being spaced apart one on each side of the axis of the hinge. Each half-ring is of substantially U-shape, the curved end 16 forming one leg of the U, a straight arm 18 the other leg and a joining piece 20 at right angles to the arm 18 the base of the U. The extremities of the arms 18 of each pair of half-rings are pivoted together by a rivet 14. A spine-forming and connecting member 12 on each side of the binding element unites all the half-rings on that side, each half-ring being engaged in a set of three aligned slots 28, 30, 32 and retained there by a rod 34 which passes through the holes formed in the parts of the half-rings which project through the slots 28. The connecting members 12 are secured at 40 and 42 to two covers 36 and the spine 38 of the binder, the connections at 42 allowing the spine to move laterally to a small degree in relation to the members 12 when the half-rings are opened. To facilitate turning the leaves in use the half-rings may be moved relatively to each other to the position shown in Fig. 4, complete separation of the curved ends 16 being prevented by a catch 44 pivoted at 50 to one half-ring and having a downturned end 52 which engages an abutment 48 on the other half-ring. Depression of a finger-piece 46 on the catch raises the end 52 against a spring bias and allows complete separation of the curved ends 16. A catch 44 may be provided at each end of the binding element. The positions of the pairs of half-rings on the connecting members 12 may be, altered by mounting them in different slots 28, 30, 32. In a modification (Figs. 13, 14, not shown) a single rod replaces the several rivets 14 as a pivot for the half-rings, the pairs of half-rings being separated by distance pieces on the rod, and the catch 44 is replaced by a catch in the form of a further rod which acts on all the pairs of half-rings. Other arrangements of slots and lugs whereby the half-rings are fastened to the members 12 are described. The half-rings and connecting members may be made of mild sheet steel or of a moulded plastic.

IPC: F16K31/68
Filed: 1969-03-21
Abstract: 1279013 Valves CONTROLS CO OF AMERICA 17 Feb 1970 [21 March 1969 14850/69 Heading F2V [Also in Division F4] In a gas control for a burner a safety valve 13 held open by an electromagnet energized by a flame sensor in a pilot flame is manually reset by a hollow plunger 22 which is provided with an inlet port 34 communicating with a passage (35) connected by a filter to chamber 16 and an outlet port 36 communicating with a pilot gas supply port 21. A screw 40 controls the flow between the inlet and outlet ports. When the plunger is pressed down for reset a cam surface thereon acts on a spring 48 to move a main gas valve 17 closed so that gas only flows to the pilot. Release of the plunger allows the valve 17 to be operated as a pressure regulator by a diaphragm 46 biased by a spring 47. Flow of gas from the main valve to outlet 68 or 69 is thermostatically controlled by two valves 51, 53, both of which are operated by a fluid containing cylinder 54 connected by a tube 56 with a temperature sensing bulb and having a piston-rod 55. Cylinder 54 is spring-loaded and rotation of knob 30 acts via a cam surface 31 on a lever 57 to alter the temperature setting, adjustment of which is by screw 58. A twoarmed lever 61 pivoted at 62 acts via a screw 51a and a surrounding spring 64 to move the valve 51 with variation of temperature. Valve 53, which acts as a by-pass for valve 51, is moved from closed to open position and vice versa by a toggle spring 65 connected between the end of one arm of lever 61 and a lever 63 actuating the valve 53. A spring-loadedcrank-lever with its two arms (76), (77) respectively in the path of movement of the plunger 22 and the safety valve 13 prevents the depression of plunger 22 before valve 13 is seated.

Title: Automatic machine for levelling printing characters
IPC: B41B5/08
Filed: 1920-06-01
Abstract: 144,288. Addressograph, Ltd., (Assignees of Duncan, J. S.). Aug. 7,1916, [Convention date]. No Patent granted (Sealing fee nol paid). Printing-surfaces.-In a machine for levelling stamped-up characters of printing-plates, the plates are brought by a carriage on to a supporting-bed, and the characters are then levelled.by means of a pressing- device, which is operated automatically by the movement of the plate on to the bed. The plate 6 is carried from the stamping apparatus to the bed 15 by a gripper 7 on a carriage 8, which is drawn along the guide 11 by a band connected to a spring drum 13. The pressing-device comprises a roller 29 mounted in a frame 19 supported by pins 20, Fig. 1, from a guide plate 17 on the frame 14. The frame also carries anti-friction rollers 21, 22 engaging the underside of the plate 17, and can also pivot about the shaft 23 of the roller 21, the roller 22 being held against the plate 17 by a spring 28 arranged between the yoke on the frame 19 and a member 25 which supports the shaft 23. The carriage 19 is reciprocated by an operating lever 27, which is loosely mounted on a constantly rocking shaft 36 and is pivoted to the member 25. The lever 27 is operated by means of an arm 42, secured to the shaft 36 and engaging a dog 48, Fig. 5, pivoted by a pin 49' to the lever 27. When no plate is present on the bed 15, the dog 48 is held clear of the arm 42 by the engagement of a pin 52 on the dog with a shoulder 53 on a latch 54, which is pivoted by a pin 55 to the frame 14 and is controlled by a spring 65. A projection 56 on the latch 54 is arranged in the path of a dog 57 pivoted by a pin 58, to a rocking lever 59 mounted on a pivot 60 on the frame 14 and controlled by a spring 63. A spring 63<1> controls the dog 57. When the carriage 8 carries a plate 6 to the bed 15 it strikes a pin 69 on the lever 59, moving it from the position shown in Fig. 5 to that shown in Fig. 2. The dog 57 thereby engages the projection 56, and moves the latch 54 clear of the pin 52, allowing the dog 48 to be moved by its spring 49 into the path of the arm 42, which then moves the lever 27 to the left. The latch 54 is then moved by its spring 65 to the position shown in dotted lines in Fig. 5, so that on the return of the lever 27 the pin 52 engages the shoulder 53, and the dog 48 is again raised to its inoperative position. The shaft 36 receives its rocking motion from the main shaft 30 by means of a gear 32, connecting-rod 34, arm 35 loose on the shaft 36, and an arm 38 fixed to the shaft 36 and connected to the arm 35 by a spring 39. If the pressing roller 29 meets with an obstruction, the spring 39 can yield so as to prevent damage to the parts.

Abstract: 434,893. Variablespeed gearing. HERBERT, SIR A., LLOYD, A. H., and HARRISON, H. T., c/o Herbert, Ltd., Canal Road, Edgwick, Coventry. May 18, 1934, No. 15040. [Class 80 (ii)] Specification 382,784, describes a change-speed gear for the spindle of a machine tool in which two opposed profiled discs adapted to engage the stems of clutch forks for gear changing, are set manually by rotation to select a speed while another speed is in use, and to be brought together axially by manual means to engage said stems and effect the gear change. According to the invention, the final act of bring- ing the discs together is effected by power means, e.g. a continuously rotating shaft of the machine tool. The profiled discs 14 are brought together by levers 12, Fig. 1, the upper ends of which engage diverging-converging cam grooves 15 on a rotatable member 16 fast with a disc part 17 carrying a spring-pressed clutch-pawl 18, Fig. 4, normally held inoperative by a bell-crank lever 20 connected to a spring- returned control rod 21. By pushing this rod, the pawl is released and engages a dog 22 on a shaft 23 continuously driven from the machine tool, and the member 16 is rotated one revolution if the push-rod has been released. The disc-part may be held by a detent 25. To prevent the final act from being carried out unless the setting has been correctly effected, the profiled discs 14 are rotated by the actuating shaft 30, through gearing 29, Figs. 1, 4, a sleeve 26 surrounding pushrod 21, and gearing 28. Notches 31 on the end of sleeve 26, corresponding to the various speeds, and dogs 32 on the push-rod, ensure that the latter cannot be actuated if the profiled discs have not been correctly set.

Abstract: 459,027. Colour photography. GROVES, W. W., 30, Southampton Buildings, Chancery Lane, London.-(I. G. Farbenindustrie Akt.- Ges.; Frankfort-on-Main, Germany) May 29, 1935, No. 15212/36. Divided out of 460,653. [Class 98 (ii)] In a process of producing coloured prints on a multi-layer film from a set of component colour pictures, the latter are printed on to a multi-film having coloured layers to form a print giving incorrect colour values in projection, and this intermediate film is printed on a multi-layer film to form a print which gives correct colour values in projection. The intermediate film may contain dyestuffs for the dye-destruction process, or colourformers for colour development, or may be dyed after printing. The component colour pictures are printed through filters of the colours to which the layers to be printed on are sensitized. The blue component picture may be printed in a final yellow layer sensitized for red or green, and the layer of the intermediate film which is printed on this yellow layer is dyed blue-green or purple. Alternatively, the blue component picture is printed on the yellow and blue sensitive layer of the intermediate film, the green component picture on the blue-green and green sensitive layer, and the red-component picture on the purple and blue or red sensitive layer, the red component picture being printed from the opposite side to the blue and green components. In the final print the yellow layer of the intermediate film is printed on the yellow layer, the blue-green layer on the purple layer, and the purple layer is printed on the blue-green layer. The green layer may be dyed with Brilliant Benzo Fast Green or Congo Pure Blue, the red layer with Sirius Red Violet or Sirius Ruby B, and the yellow layer with Sirius Yellow R or Chrysophenine G or W. With films having two layers on one side of the support, and one on the other, the process is applied only to the superimposed layers. The colour component records may be in a lenticular bi-pack, and the intermediate' film, on which the lenticular front film is printed, carries superposed red and blue-green layers sensitized to red and blue respectively, and is processed by dye-destruction. The Blue component picture is printed with a green filter and the green component picture with a red filter. Intermediate films in which the difference from the final film is in gradation or in intensity of colouring are referred to.

Abstract: 1382491 Spring power storing mechanisms G HENRY 30 March 1972 15227/72 Heading F2S [Also in Division H3] The Specification describes a spring drive arrangement 19, 20 for apparatus for automatically scanning a waveband in a wireless or T.V. receiver (see Division H3). When a key 31-34 is pressed in a projection 59 moves a slide 61 so as to operate a frequency range switch 62, 63. Also the push rod 28 associated with the key 31-34 which has been pressed moves a part 25 which moves the pulley 24 so that an indicator drum 23 is returned to its initial position and tensions the spring 20. The part 25 also drives gearing 29, 30-37 which is latched by pawls 39, 48. A projection 53 operates switch contacts 52 1 , 52 2  to provide a holding current for an electromagnet 49 so that pawl 48 is disengaged from gear 47 to start a signal sweep, the spring 20 forming the motive element of the apparatus. A rotor 41 co-operates with the polepieces 50 of the electromagnet 49 to form an eddy current brake so as to enable the gear mechanism to turn at a constant rate. The tuning of the receiver is varied by a tuning voltage, applied to variable capacity diodes 10, obtained by rectifying at 15 the varying output from the coil 11 caused by movement of a ferrite core 12 connected to the cable 19. When a signal is received the output from the IF amplifier 103 causes the electromagnet 49 to be deenergized so that pawl 48 arrests the gear 47 and stops the signal sweep. The sweep may be restarted by pressing a push-button 54.
