Title: Improvements in and relating to sheet delivering apparatus for use with printing, cutting and other machines
IPC: B65H29/42
Filed: 1925-02-25
Abstract: 252,278. Molins, W. E. Feb. 25, 1925. Delivery apparatus. - A machine for severing strips or sheets from a web and stacking the same in an upward direction in a vertical receiver is described in connection with an intaglio printing-machine from which the printed web is delivered by a pair of rollers 2, and is severed into sheets or strips by a fixed cutter 4 and a rotary cutter 3 on a shaft 14 driven from the printing-machine. The cutting-device is preferably of the kind set forth in Specifications 190,202 and 245,261, [Class 31 (i), Cutting and severing machines &c.], or the fixed knife may be bowed so that the web is cut simultaneously from each side towards the centre of the web. Before the printed web is severed, its end is drawn by suction against the surface of a suction drum 7 provided with a central row of apertures, the drum being driven by sprocket gearing at a greater speed than the rollers 2, so that the web is drawn taut during the cutting operation. A bed 5, which is preferably arranged as a hollow chamber for blowing air on the printed sheets, is fitted below the drum 7. The drum 7 is fitted at each side with a groove in which are arranged belts 7a passing over pulleys 17, 16. The belts 7<a> reverse the motion of the severed sheets, and separate them from one another, and carry them to stacking-mechanism which, as shown, comprises four rotary helical members 21 formed at their lower ends with helices of coarse pitch, and with discs 20 provided with suction apertures which periodically register with suction openings and draw the severed sheets into contact with the discs and thus arrest the longitudinal motion of the sheets. The leading-edges of the sheets are prevented by flanges from dropping below the level of the discs 20. As the sheets are raised by the helices 21, they are kept separated from each other until the top of the helix is reached. The sheets are thus advanced in spaced parallel relationship, and are acted on by air blast from a pipe 26 which completes the drying of the sheets, and presses the edges against a vertical guide 25. For separating the stack into piles of predetermined numbers staggered relatively to one another, the guide 25 is arranged to be moved to and from the pipe 26 at the required intervals by mounting the guide member on links 27, 28, operable by a link 31 and lever 32 controlled by a cam 33 connected to a spindle 34 by a ratchet and pawl fitted with an operating-knob 33b. The cam 33 can be set to zero while the machine is running, and is driven by reduction gearing from the main shaft of the machine in such a manner that the guide 25 is moved inwards after say 250 sheets have been delivered, and is returned after a further 250 sheets have been delivered. The stacker is preferably mounted on a yoke 41 permitting it to be swung to a horizontal position to give access to the cutters.

Title: Improvements in or relating to a method of and an apparatus for putting under pressure and maintaining under pressure fluid contained in a reservoir carried by a vehicle having hydraulically operated brakes
IPC: B60T11/22
Filed: 1957-02-15
Abstract: 846,127. Hydraulic brakes. REGIE NATIONALE DES USINES RENAULT. Feb. 15, 1957 [Feb. 17, 1956], No. 5258/57. Class 103 (1). An hydraulic master cylinder for vehicle brakes has a passage 7 branched off the main cylinder leading to a space below a piston 2 and sealing cap 3 in an auxiliary cylinder. When the main piston D is operated, fluid-pressure from the main cylinder drives the piston 2, 3 upwardly compressing spring 6 until its movement is limited by abutment with the top of the space. Liquid is ejected from above the piston 2, 3 past ball-valve 4 and by conduit 16 to a spring accumulator 8. The accumulator 8 has a piston 9 therein, the movement of which is limited between stops 12 and the abutments of stop 12a with the top of the tank, upward movement of the piston compressing spring 10. By operation of a distributer valve 19, the pressure differential existing across the piston 9 may thus be used to operate a servo-piston 20 for operating other devices. The amount of fluid passed from the main cylinder through passage 7 to operate the auxiliary piston 2, 3 is not sufficient to materially effect the normal operation of the master cylinder.

Title: Improved device for registering the time of locking of receptacles for tickets, rings, balls, or the like tokens
IPC: G07C1/32
Filed: 1924-03-03
Abstract: 229,864. Birtwhistle, H. March 3, 1924. Time-checking apparatus, check and token.- Apparatus for registering the time of locking of receptacles for tickets, tokens &c. comprises a casing containing a stop-watch and a sliding plate member adapted to co-operate with hasp members on the receptacle to simultaneously lock the receptacle and stop the watch. The casing 9 has a lid 10 with a cylindrical part 11 adapted to hold the stop-watch 12 so that it is visible through an aperture 17 in the casing. The lid is locked to the casing by passing a pin 28 through a hole 29 in the casing and operating a lock 15 by a key so as to move a bolt 30 behind abutments 31, 32. A fork 22 on a flat plate 20 slidably mounted in the casing and having a hole registering with a hole 18 in the casing, then engages with the stop pin 13 of the watch 12. A spring 24 tends to move the plate 20 in a direction to stop the watch, but movement is prevented by a catch-plate 19 pivoted to the casing and abutting against a flange 23 on the bar 20, this catch-plate covering the holes in the plate 20 and casing 9. The leather bag 1 for the tickets &c. is closed by pulling cords 3 to enclose a plate 4, having a hole 6, by a cover plate 5 having a hasp 7, which then protrudes through the hole 6. The hasp 7 is then inserted in the hole 18 pushing up the catch-plate 19 to release the bar 20 and allow the spring to move it, thus stopping the watch. This movement also causes the bar 20 to engage with a slot 8 in the hasp 7 thus locking the bag and locking the casing 9 to it. Spring catches 33 prevent unauthorized return movement of the plate 20.

Abstract: 1,001,104. Investigating plasmas photoelectrically. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 21,1963 [Feb. 15,1962], No. 5893/62. Heading G1A. The electron temperature and density of a plasma are measured by projecting a laser beam through the plasma and photoelectrically detecting light scattered from the beam. Light from the laser is directed through the plasma several times by reflection between a mirror M and the front surface of the laser. Light emerging at 90 degrees to the incident beam includes light scattered by the electrons which is polarized and unpolarized self emission from the plasma. The former passes through a polarizing beam splitter S to a photomultiplier PM2, whilst the latter is split to fall equally on photomultipliers PM1; PM2, the difference of outputs of which, indicative of the electron scattered light, is displayed on an oscilloscope O. Several systems of beam-splitter and photomultipliers are provided, each with a different interference filter F so that the intensity of scattered light at different wavelengths about the incident wavelength may be measured. Electron temperature shows up as a Doppler broadening, and plasma drift as a Doppler shift of the scattered light. Electron density is determined by comparing the total amount of light scattered with the incident beam power measured by a photomultiplier PM3. The effect of stray light is reduced by baffles D, the absorber H and by making the pass bands of all filters F differ from the incident wavelength. The laser may be modulated and amplifiers A 1 , A 2  tuned to the modulation frequency.
