Title: Sheet-fed rotogravure machine for multicolour printing
IPC: B41F21/00
Filed: 1953-08-28
Abstract: 761,456. Rotary printing-machines SCHNELLPRESSENFABRIK KOENIG & BAUER AKT.-GES. Aug. 28, 1953 [April 9, 1953], No. 23880/53. Class 100(2) A multi-colour sheet-fed rotogravure machine has means for registering the sheets before passing them through each printing couple, the couples being disposed in line one behind the other on one side of a sheet-feeding apparatus, and one or more sheet reversing devices are included each adapted to be rendered operative or inoperative whereby it is possible to print sheets on one side or on both sides in several combinations according to the number of printing couples provided. For example, with five couples, a sheet may be printed : 1) on one side in five colours : 2) on one side in four colours and on the other in one colour : 3) on one side in three colours and on the other in two colours. The sheets are dried between each printing operation and are finally delivered by tape conveyers on to either of two piles, as shown. Sheets 2 are fed from a pile 1 on to a table 13 in overlapping relation where they are registered at the front and sides. A variable-speed drum 14 receives the sheets and delivers them to an impression cylinder 15 co-operating with a forme cylinder 16. An endless conveyer chain 17 first conveys the sheets through a drying chamber and then to a point adjacent an endless chain conveyer 18, Fig. 5. If the sheets are to be printed on the same side by the next couple, the sprocket 6 of the conveyer 17 drives the conveyer 18 in the direction of the arrow A, and the conveyer 18 takes the sheets from the conveyer 17 and deposits them in a conveyer belt 10 which feeds them over the table 23 of the next couple 25, 26. If, however, the sheets are to be printed on the reverse side, they are taken from the conveyer 17 by a gripper drum 3 which now drives the conveyer 18 in the direction of the arrow B, and the conveyer 18 takes the sheets from the drum 3, carries them around the sprockets 5a, then over the belt 10 in reversed condition. The sheets are deposited on the belt 10 with their front edges against an adjustable stop 34, and the belt then conveys them over the table 23 of the next couple 25, 26. A similar reversing conveyer and gripper drum device is arranged between each printing couple. The conveyer chains 18 are provided with two sets of sheet grippers 7, 8, which are used according to the direction of travel of the chains, and with spring-loaded adjustablymounted rollers 9 which roll over and press the sheets on the belt 10 when the grippers 7 or 8 are opened. The grippers are opened by an adjustably-mounted cam 12. A plate 35 supports the belt 10 and co-operates with the rollers 9. The chains 18 can be driven at variable speed to suit. the speed of the conveyer 17, and to deliver the sheets on the feed table at reduced speed. Supporting wires, tapes, rods &c. may be associated with the chains 18 to form a support for the sheets.

Patent GB-721219-A (GB)
Title: Improvements in or relating to the production of friction material
Inventor: COFEK HENRY JOHN
IPC: C08K7/12
Filed: 1951-10-16
Abstract: A composition for making friction material comprises short fibre asbestos, fillers, and as the principal binder therefor, an aqueous solution of a thermosetting resin, which is an alkalicatalysed phenol-formaldehyde partial condensate, having a solids content of from 50 to to 80 per cent by weight, the resin having a water solubility of 1 part resin solution to from 3 to 8 parts water as referred to a 50 per cent solids solution.  In making the resin solutions from phenol, cresols, cresylic acid, xylenol, resorcinol or mixtures thereof with formaldehyde or a polymer thereof, the aldehyde is used in excess, e.g. 2 1/2 mols. to 2 mols. of phenol, and the alkali is preferably a 30 to 40 per cent aqueous solution of NaOH or KOH.  In one example, phenol and formalin are charged into a reaction vessel and heated to 150 DEG  F., and caustic soda solution is added at intervals in 5 equal parts during 1 hour, the temperature rising to a point at which boiling and refluxing commences.  Tests are then made to determine the degree of condensation by the water-solubility. When the desired degree of condensation has been reached, the reaction is stopped and the solids content of the solution is adjusted, if required.  In another example is described the preparation of a cresylic acid-formaldehyde condensate.  The friction material may be made by mixing the resin solution with the asbestos and fillers, reducing the mix to a mass of non-coherent granules and compacting and shaping the material into a continuous strip form, for example, 29.7 parts (by weight) of a 53.3 per cent solids aqueous alkali-catalysed phenol-aldehyde condensate, 42.2 parts of short fibre asbestos, and 28.1 parts of conventional friction material fillers (e.g. barytes, litharge and graphite), including lubricants, friction augmenting agents and resin cure accelerators, were mixed in a dough mixer.  The resulting loose mass of small pellets was aged at room temperature, pulverized in a hammer-mill, and compacted into strip form by feeding between rolls of a roll extruder, preferably together with a wire strip to form a wire mesh reinforcing backing. The strip material may then be cut into desired lengths and cured at 400 DEG  F.  Natural or synthetic rubber, together with a hydrocarbon solvent therefor, may replace a minor proportion of or be added to the resin solution.

Abstract: 388,805. Automatic regulation. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Thompson, L. W. ; 53, Baker Avenue, Schenectady, New York, U.S.A.) Aug. 28, 1931, No. 24277. Convention date, Aug. 28, 1930. [Class 38 (iv).] In an automatic voltage-regulating system a rheostat and a normallv short-circuited resistance are in series in the exciter field of the generator to be regulated, and a small deviation of voltage from the normal value causes a slow adjustment of the rheostat but a larger deviation causes either an intermittent short-circuiting of the rheostat or an intermittent open-circuiting of the resistance. A variable rheostat 9, in series with the normally short-circuited resistance 8, in the field of the exciter 5, is adjusted by a reversible motor 14 controlled by the contactors 16, 17. The controller comprises contacts 38, 26, continuously rotated by a motor 42, which co-operate respectively with contacts 36, 37 and 24, 25 mounted on a lever 31 coupled to' a restrained motor 32. If the voltage is slightly high, contact 25 engages toothed contact 26 and the contactor 16 intermittently completes the circuit of motor 14 which slowly adjusts the rheostat 9. If the voltage variation is larger the lever 31 is further rocked, the strip 28 bending, and contact 37 intermittently engages the disc 38 to complete the circuit of the contactor 19 which intermittently inserts resistance 8 into the field circuit. A similar sequence of operations occurs when the voltage is too low.
