Title: Improvements in or relating to photocopying machines
Inventor: HALDEN JOSEPH GERALD BROCTON
IPC: G03B27/22
Filed: 1957-08-07
Abstract: 900,816. Photographic contact-printing apparatus. OZALID CO. Ltd. Nov. 7, 1958 [Aug. 7, 1957], No. 24900/57. Class 98 (2). [Also in Group XXX] In a photographic contact-printer in which superposed original and light-sensitive sheets are conveyed by an endless belt or band conveyer past a light source, the printing section conveyer operates at a constant speed and a feed conveyer accelerates the superposed sheets to this speed so as to transfer the sheets to the printing section conveyer without snatching. As shown, a motor, driving sprocket 20, accelerates the belts 3, 4 of the feed conveyer to the speed of the belts 8, 9 of the printing section conveyer, the latter being driven independently at constant speed to provide a uniform photographic exposure during the conveyance of the sheets by belts 9 around a translucent internally illuminated cylinder. Chain 18 drives sprockets 21 and 22 and a freewheel 19 is provided between roller 10 and sprocket 22 to allow belts 3, 4 to remain stationary or move at a slower speed than belts 8, 9. A freewheel is also provided at 17. The sheets may be superposed by hand on a section of belts 4 not overlaid by belts 3 or, alternatively, the sheets can be automatically superposed from a stack of originals and a roll or stack of light-sensitive material using the apparatus disclosed in Specification 853,859. The feed conveyer is constructed with a minimum of inertia so that a high starting torque motor rapidly accelerates the conveyer to the speed of belts 8, 9 and is prevented by freewheel 19 (and, if necessary, a brake) from exceeding this speed. Belts 3 and 8 pass over independently rotatable sections of roller 6 and alternate belts 8 pass over roller 13. Belts 8 and 9 are pressed together by contact plate 11. Specifications 895,945 and 895,946 also are referred to.

Abstract: 512,288. Centrifugal sprayers. WARMETECHNISCHE GES. FRANKFURT AU MAIN GES. Aug. 24, 1938, No. 24929. Convention date, Aug. 24, 1937. [Class 69 (iii)] [Also in Group IV] Liquid for moistening fabric and webs is thrown centrifugally through perforations in the wall of a sprinkler cylinder, into the interior of which it is fed, into the path of a rotating fan cylinder provided with radial or helical blades and arranged beside it in a casing, by which means the liquid is atomised. Water may be fed through a perforated pipe 9 into the interior of a perforated cylinder 3 having a covering 24 of material pervious to liquid on its surface, and liquid thrown out through the cylinder 3 is atomised by a rotary fan cylinder 4 and thrown through an opening 16 in a casing 15 which encloses the cylinders. The web 18 to be moistened is passed in front of the opening 16 on guide rollers 17. The Specification as open to inspection under Sect. 91 comprises also an arrangement wherein the opening 16 is formed in the vertical side wall of the casing and a gutter is formed around the top edge. The bottom of the casing may also slope to a drain, and a baffle may be provided to prevent liquid particles from being thrown direct through the opening on to the web. This subject-matter does not appear in the Specification as accepted.
Patent GB-953376-A (GB)
Title: Plant watering system
IPC: A01G29/00
Filed: 1961-07-11
Abstract: 953,376. Soil irrigation. R. H. COOMBES. Oct. 11, 1962 [July 11, 1961], No. 25045/61. Heading A1B. In a plant watering system water is fed from a supply pipe 1 controlled by a ball valve 4 to a tank 3 from which water is dis charged at predetermined intervals through an outlet pipe 7, controlled by a solenoid-operated flow valve 8, and apertured pipes 10 buried in the soil in which the plants are grown. A control circuit for the apparatus comprises switches A and B located above the float arm 5, switch A being normally closed and switch B open. A switch controlling arm 14 (Fig. 3) rigidly secured to float arm 5 closes switch B when the ball 4 has reached a predetermined upper position and opens switch A at a predetermined lower position, a solenoid 15 serving to hold switch B in its closed position. Switch A is connected to solenoid 15 and, through lead 19, to a solenoid 20 in parallel with an electrically operated pump 9 located in outlet pipe 7. A vertical spindle 22 in tank 3 carries at its lower end an arm 25 having a member 26 which can be swung against the inlet of pipe 7, and at its upper end an arm 27 of ferrous material biased by spring 28 to a position in which member 26 seals pipe 7. As tank 3 is filled, the arm 14 approaches switch B to close switch B. Switches A and B are therefore both closed so that solenoid 15 is energized, solenoid 20 energized to attract arm 27 to move the sealing member 26 away from pipe 7, and pump 9 is operated to force water through the pipes 7 and 10. As the water level in tank 3 falls, arm 14 moves away from switch B which is prevented from opening by solenoid 15 until arm 14 opens switch A thereby breaking the circuit to solenoids 15, 20 and pump 9. The cycle is then repeated. In a modification, an outlet pipe 29 extends into tank 30 and is bent upwardly to form a water trap, a domed member 31 covering the end of pipe 29 and a pump 32 being located in part 29<SP>1</SP>. Switches A, B are actuated by an arm 34 carried by float 33. As tank 30 is filled, the water in the trap rises in the part 29<SP>1</SP> until the height H of water in tank 30 above pipe 29 equals the height H<SP>1</SP> of water in part 29<SP>1</SP>. Siphoning then occurs, switch B being adjusted so that pump 32 is energized just prior to siphoning and switch A being placed so that float arm 34 operates A to de-energize pump 32 just before siphoning finishes. A container filled with liquid fertiliser may be connected to the main outlet pipe or a hopper containing powdered fertiliser located over the water tank.
