Class 98(2) A process of making a chromium inkrefusing, ferrous metal ink-accepting, plate or cylinder with particular attention to the cleaning of the inking areas comprises (1) initially cleaning the base plate which may be iron, steel or preferably low carbon steel, as with pumice and hydrochloric acid, and chromium plating it at high current density; (2) sensitizing as with gumbichromate, exposing for instance under a half - tone positive, and washing to remove soft resist; (3) etching as with calcium chloride - hydrochloric acid to remove bared portions of the chromium; (4) cleaning to produce bright and silvery image areas as by rubbing a predominantly alcoholic liquid containing ferric chloride, ammonium chloride, bismuth oxychloride and pumice powder on the plate with a felt pad, cleaning which does not damage the resist-protected chromium areas; (5) removing cleaning material with an organic solvent as of an alcohol-hydrocarbon mixture; (6) applying a protective varnish layer; (7) removing light-hardened resist from under the varnish as with a detergent solution or dilute citric acid and drying; (8) removing the varnish with a solvent; (9) applying a conventional (black) ink to the plate and desirably also dilute phosphoric acid which keeps the chrome areas non-receptive to ink and apparently also minimizes unwanted oxidation of the ferrous inking areas; (10) and finally, applying a protective gum arabic coating which is removed when the plate is to be placed on the press for printing. The ink of step (9) may be removed with a solvent if the plate is to be used with ink of a different colour. In printing with the platea water-soluble bland compound such as glycerine and specifically the latter together with a little ammonium bichromate should be added to the fountain water to avoid defects in very long printing runs. Reference has been directed by the Comptroller to Specification 483,349 [Group XVI]

Title: Improvements relating to steam valves
Inventor: WHITEHOUSE REGINALD GEORGE
IPC: F16K31/143
Filed: 1954-11-12
Abstract: 783,101. Valves. BRITISH THOMSONHOUSTON CO., Ltd. Nov. 11, 1955 [Nov. 12, 1954], No. 32842/54. Class 135. In an hydraulicallyoperated emergency stop valve for a steam turbine, comprising a balanced main steam valve 5 mounted in the valve inlet chamber 1 and a pilot by-pass valve 6, the operating spindle 8 common to both valves is made in two parts connected together by a thrust bearing 11, the lower rotatable part being operable through bevel gearing and a handwheel 10 and screwthreadedly connected to a spring-loaded, piston-like member 4 engageable with a seating 15. The member 4 carries a flexible diaphragm 18 which coacts with a seating 16 prior to the engagement of the seating 15 by the member 4. To set the valve in its normal open position the handwheel 10 is first rotated in a valve closing direction to move the member 4 upwardly against its spring to seat the diaphragm 18. Emergency trip gear is then set to establish oil pressure beneath the diaphragm which opposes the steam pressure and the spring whence the valves 5 and 6 may be manually opened and will remain open until the emergency gear trips or a failure in the oil supply occurs. When the valves are open leakage of steam past the upper part of the spindle is prevented by the engagement of a piston member 13 on a spindle guide bush 9. The flexibility of the diaphragm ensures that when the valves are open the member 13 and the diaphragm 16 both remain seated despite any expansion differences between the spindle and valve body. A strainer is fitted in the inlet chamber and any leakage past the spindle that might occur escapes through an outlet 14. Specification 611,691 is referred to.

Filed: 1970-07-08
Abstract: 1,270,766. Automatic musical instruments. LUIS CONGOST S.A. 8 July, 1970 [22 Dec., 1969], No. 33070/70. Heading G5J. A toy musical instrument comprises a plurality of mutually parallel guides 3 arranged axially on a roller 1, and reference lines, not shown, marked on the roller surface, with striker tabs 2 located at the intersection of the reference lines and the guides. The striker tabs 2 cause the sounding of metallic strips, either by striking them directly when the roller is rotated, or by striking the rear portions 30 of pivoted hammers 33, which causes the hammers to strike the metallic strips 33. The striker tab 2 may be pivoted on the guide 3 to allow one of its edges to engage the hammer 33 when the roller is rotated in the correct way, and, in event of opposite, incorrect rotation, the other side of the striker tab engages the hammer which causes the striker tab to turn about the guide 3 to an inoperative position. The striker tab may subsequently be reinstated to its operative position manually. The roller may be rotated by a mechanical handle or by an electric motor, so that the roller moves more slowly than the driving means. This may be achieved by gears or by means of an endless belt or chain operating on pulleys, or sprockets, respectively.
