Title: Improvements in or relating to the driving mechanism for printing machines
IPC: B41F13/00
Filed: 1954-06-29
Abstract: 757,054. Printing machines. GLOCKNER, P., [trading as GLOCKNER, P. [Firm of]]. June 29, 1954 [Aug. 5, 1953], No. 19009/54. Class 100 (2). Driving arrangements.-A printing machine is driven from a constant speed motor through a continuously variable gear, the motor also driving, at constant speed, a pump for supplying vacuum to the suction sheet-feeding apparatus. In the form of Fig. 1, the motor 3 drives the main shaft 1 of the printing machine 2 through a belt 4 passing round an expanding pulley 7 on the motor shaft 5. This pulley consists of two cones keyed to the shaft, one of the cones being slidable along the shaft and spring-loaded towards the other. Another pulley on shaft 5 is connected by a belt 11 to the driving pulley 12 of the pump 13. Both the motor and the pump are mounted on a sliding base 14 movable towards and away from shaft 1. As the motor is moved away the tension of the pulley forces the cones apart, reducing the effective diameter of the pulley and consequently reducing the speed of the machine shaft 1. The base 14 is displaced by cranks 19 connected to a shaft 18, an arm 20, Fig. 2, on the shaft being connected by a pivoted nut 21 to a threaded rod 22 rotated to displace the base by a handle 23 acting through bevel gears 24. A pointer 26 on shaft 18 cooperates with a scale to indicate the speed of rotation of the printing machine. The expanding pulley may alternatively be controlled by the tension of the belt derived from an adjustable jockey pulley running against the belt. In a modification the expanding pulley may be controlled directly, the belt tension being suitably maintained by the jockey pulley.

D., 14, Abercorn Gardens, Barley Lane, Romford, Essex, and TATE & LYLE, Ltd., 21, Mincing Lane, London. June 28, 1934, No. 19145. [Class 97 (i)] Apparatus for effecting colorimetric determinations comprises means whereby a liquid to be tested and a reagent producing the coloration are brought together automatically in the appropriate proportions, a cell to which the mixture is delivered, a source of light from which light passes through the mixture in the cell to fall on a photo-electric cell, and means associated with the photo-electric cell to indicate or record the response of the cell to the light passed. The apparatus is particularly suited for determining the sugar content of waste water from sugar factories and refineries, using Molisch's reaction, and apparatus for this purpose is described. A storage vessel 1, Fig. 1, contains a solution of alpha-naphthol in concentrated sulphuric acid which is delivered at a constant rate to a reaction vessel 4. The waste water to be tested flows continuously through a metal cylinder 10, provided with a valve 13 which operated by the relay 15 delivers a fixed quantity of water to the reaction vessel 4. The mixture of water and reagent siphons over into a glass-sided lead cell 6. The relay 15 is actuated by a pair of contacts 29, 30 in the cell 4 becoming short-circuited by the rising reagent, and conriecting the coil 15 to a source of potential 28, Fig. 3. The armature 14 releases the valve 13 and also switches on a Warren or other suitable synchronous motor 18 which slowly rotates a cam 19. After a delay of threequarters of a minute the cam 19 causes a mercury switch 22 to connect a lamp 24 to the source 28. The light from the lamp 24 passes through the cell 6 containing the coloured reaction mixture and falls on a photo-electriccell 25 which is in series with a thread recorder (not shown), embodying a suspended coil microammeter. Current is supplied to the photoelectric cell and to the relay circuit 27 of the thread recorder only when the lamp is passing current. The cell 6 is made only one-third of the volume of the liquid discharged from the vessel 4, so that the cell is flushed out before each test.
