Title: Improving the ductility of ruthenium
Inventor: BETTERIDGE WALTER
IPC: C22C5/00
Filed: 1962-03-19
Abstract: The workability of ruthenium is improved by melting it under neutral conditions in contact with one or more of the elements: Zn, Cd, Bi, Ti, Ge, Ba, Hf, Ce, Er, Gd, Ho, La, Pm, Sm, Yb, Y; e.g. Zn in the range of 0.05-5% byweight of Ru. The element or elements may be pressed into a compact of Ru powder, e.g. prepared by the reduction of ruthenium ammonium chloride in hydrogen, which is placed and melted in an argon arc furnace, preferably using a Ru electrode, with the added element or elements at the bottom. For example, a 0.2 g. chip of Zn may be pressed into 40 g. of Ru powder.  After melting the compact and solidifying, the solid metal may be hot-rolled in a plurality of passes with intermediate heating to 1450  DEG C.  The Zn may be replaced by 0.02 g. of Ce. Melting may be performed in vacuum.

Title: Improvements in or relating to a rotary duplicator for printing a predeterminable number of lines from stencils
Inventor: RITZERFELD GERHARD
IPC: B41L19/04
Filed: 1969-02-27
Abstract: 1,213,604. Rotary duplicators. G. RITZERFELD. 27 Feb., 1969 [29 Feb., 1968], No. 10453/69. Heading B6C. In a rotary duplicator for printing one, two or three selected lines on copy sheets by predetermined tripping of the impression cylinder the latter is actuated by three cams rotating with the printing cylinder and having a single follower, which selectively may be common to all three cams and which, acts through lever linkages to move the impression cylinder. At each of the positions of the cams which provide single, double or treble lines on each copy sheet, electrical switch means associated with electromagnets and levers and follower rollers are provided such that through actuation thereof a succession of copy sheets may issue from the duplicator each bearing the same number of lines i.e. one, two or three, but such lines being different on each copy sheet. To effect single line duplicating, each copy sheet bearing a different line image, it is sufficient to switch on the machine and press a push button but for two and three line duplicating bearing lines a control rod is twisted into a first position-for two lines-and a second position-for three lines.

Filed: 1971-04-21
Abstract: 1386772 Endless conveyers PURDY MACHINERY CO Ltd 20 April 1972 [21 April 1971] 10455/71 Heading B8A Bottles which are to be oriented for a labelling machine (not shown) are conveyed by an endless conveyer 1 past two sensing rollers 6, 7 which control actuation of a plate 13 for deflecting bottles towards a stationary plate 14. The bottles, after being spaced by a star wheel 4 (see Specification 1,386,771) are guided by rails 2, 3, 11, 12 of which the rail 11 has an oblique portion 16. A bottle which is correctly oriented, i.e., with a plain face toward the guide rail 3, causes no relative movement between the rollers 6, 7 and the bottle is carried straight on by the conveyer 1. If a bottle has an embossed side facing the rail 3, the rollers 6, 7 sense this and the plate 13 is pivoted to cause the bottle to move partially on to the plate 14. The continued movement of the conveyer, in cooperation with the plate 14 and the rail part 16, causes the bottle to be turned through 180 degrees. The deflecting plate 13 and the star wheel 4 are pneumatically controlled. For orienting "square" bottles, fingers under the control of the sensing means may be projected into the path of a bottle. Electronic control is also specified.
