Printing plate ends 4 (3 is not shown) are clamped in the longitudinal gap 1 of a forme cylinder 2 by identical mechanisms. Each comprises a clamping jaw 17 pivotable about an adjustable axis 18 and moved into plate clamping position by an eccentric rod operable from its ends. The axis 18 of the jaw 17 is mounted at the end of a threaded bolt in a tension bar 7 which also mounts a strip 26 which forms the lower clamping surface holding the plate end. This strip is moved into gripping position by a wedge rod 23, which is located between the bar 7 and the strip, when the bar 7 is moved in the peripheral direction of the cylinder through actuation of threaded bolts 13 so as to tension the printing plate. Thus plate tensioning simultaneously tightens the grip on the plate. Antifriction surfaces are provided between the eccentric rod 30 and the respective contacting surfaces of the jaw 17 and the bar 7, whilst a friction surface is provided on the upper surface of the strip 26. In a modified mechanism the rod 23 and the strip 26 form a unified structure.

Patent GB-933804-A (GB)
Title: Improvements in processing hydroxyethyl cellulose
IPC: C08L1/28
Filed: 1961-10-09
Abstract: An alkali-soluble hydroxyethyl cellulose pellet is made from fibrous hydroxyethyl cellulose crumb having from 2 to 8% of ethylene oxide substitution, the pellet having a bulk density which varies from the high range of 30 to 35 lbs. per cu. ft. when the moisture content of the crumb is 40%, to the low range of 20 to 25 lbs. per cu. ft. when the moisture content of the crumb is 58%, the pellets being free of surplus glazing and readily dispersible in water.  The hydroxyethyl cellulose, suitably derived from cotton linters or wood pulp (see U.S.A. Specification 2,847,411), is preferably shredded or fluffed before extrusion in a pellet mill.  Preferably, 0,05 to 0,20% by weight of a surfactant is added to the hydroxyethyl cellulose crumb before shredding or fluffing.  Such a surfactant, e.g. polyethylene glycols and polyethylene-polypropylene glycols, acts p  both as a fibre lubricant and dispersant, allowing easy fluffing and improved re-dispersion of the formed pellets.  Addition of such a surfactant allows the bulk density of the pellet at each moisture level to be raised by 10 to 20%, without loss of dispersibility.  In an example, a hydroxyethyl cellulose feed stock (4% ethylene oxide substitution), of moisture content 45% and containing 0,1% of surfactant, is shredded and extruded into pellets.  The pellets are dried to 7% moisture content, and have a bulk density of 30 lbs. per cu. ft.

Title: Improvements in and relating to telemetering systems
IPC: C09B7/10
Filed: 1930-12-03
Abstract: 368,775. Electric signalling systems. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitõts - Ges.; 2, Friedrich Karl-Ufer, Berlin.) Dec. 3, 1930, No. 36452. Convention date, Dec. 3, 1929. [Class 40 (i).] In a device for transmitting indications or measurements to a distance, employing a lightsensitive cell, the lighting of which is controlled by a compensating system, the current or pressure which is used in the signalling circuit and which influences the compensating system, is controlled by the cell without the employment of regulating members. In the construction shown in Fig. 1, a power meter 1 transmits a torque to a compensating instrument 3 through a spiral spring 2, whereby a shade 4 is moved to determine the amount of light received by a photo-electric cell 6 from a lamp 5. The current through a receiving instrument 9 is thereby varied in such a way as to cause the instrument 3 to exert a force to balance the torque produced by the power meter. The indication of the instrument 9 then corresponds to the reading of the meter 1. In the arrangement shown in Fig. 2, the invention is applied to the transmission of liquid-level indications. An amplifier, for example a thermionic valve, may be connected between the cell 6 and the instrument 9. Instead of employing the current in the signalling circuit to determine the reading of the receiving instrument the voltage may be used, in which case the compensating instrument may be connected in parallel with a resistance in the anode circuit of an amplifying valve and a volt-meter functioning as the receiving instrument. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification in which two spiral springs are used, one connected to the top of the instrument 1, the other to the axis of the compensating instrument 3. In a further modification, shown in Fig. 6 (Cancelled), a relay 15 energized by photo-electric cell currents short-circuits a resistance 16 in the signalling circuit. Choking coils 17 are connected in series with the instrument 3 and a condenser 18 is in parallel therewith. This subject-matter does not appear in the Specification as accepted.

Abstract: 427,571. Presses for separating liquids from solids ; hydraulic machines. ROSE, DOWNS, & THOMPSON, Ltd., and DOWNS, L. H., Old Foundry, Hull. Dec. 30, 1933, No. 36719. [Class 46] The position of a tapering member, which is placed in the outlet of a worm extrusion press to regulate discharge of solid material therethrough, is adjusted hydraulically. As shown in Fig. 2, the conical member 6 is connected to a cross-head 8 the ends of which are connected to the plungers 9 of hydraulic cylinders 11 to which liquid under pressure is supplied by a hand or powerdriven pump. In the modification shown in Fig. 4 there is only one hydraulic cylinder 11 the plunger 9 of which is connected to a lever 19 fulcrummed in fixed brackets 20 and having a bifurcated end detachably connected to the member 6 by screwed bolts 23. Fig. 3 shows an arrangement ot valves for controlling the liquid supply and discharge to the cylinder or cylinders 11. Operation of a hand-wheel 15 allows a check valve 113 to open so that liquid passes from a pump through a pipe 17 to one end of the cylinder and causes the piston to move the part 6 towards the press chamber. The liquid can exhaust from this end of the cylinder when a hand wheel 16 is turned to allow a check valve. 117 to open, the liquid passing away through a vent 122. The working pressure on the part 6 will then cause the piston to move in the reverse direction. If however the extrusion press is not working, the wheel 16 can be turned further so that a valve 120 closes the vent. If the valve 113 is then allowed to open liquid under pressure will pass to both ends of the cylinder through pipes 17, 18 respectively and the piston, which has sides of unequal effective area, will move in the reverse direction and withdraw the part 6 from the press chamber.
