Abstract: 1,150,313. Turbines. JOSEPH LUCAS (INDUSTRIES) Ltd. Oct.31, 1966 [Nov.18, 1965], No. 49003/65. Heading F1T. [Also in Division D1] An air turbine 16 driving a yarn winding spindle 13 has nozzles 22 directing driving air on to the turbine blades 16a for normal running and oppositely inclined nozzles 21 through which the air can be directed for braking of the turbine. Air is supplied through an inlet 25 and is directed to passages 17 or 18 and nozzles 22 or 21, respectively, according to the position of a rotatable ported valve member 24 having a spring-loaded actuating arm 27. A slidable piston 31 runs within a cylinder 30 in member 24 and is acted upon by governor weights 33 so as to control the opening of the ports leading to the nozzles and thus the speed of the turbine 16. A one way clutch 34 between spindle 13 and a stator member 35 prevents reversal of the turbine when braking air is supplied through nozzles 21.

Abstract: 1451698 Printing plates XEROX CORP 19 Nov 1974 [27 Dec 1973] 49968/74 Heading B6C A lithographic printing plate is prepared using a silicone gum and two catalysts. The first catalyst is effective to cure the gum at a first temperature. A suitable substrate, e.g. paper, metal or plastics, is coated with a coating comprising the gum and the two catalysts, and the layer at least partially cured, and a particulate image applied. The particulate image coacts with the second catalyst at a second temperature higher than the first temperature to degrade the cured silicone.
