Title: Improvements in or relating to electrical contacts
IPC: H01H1/0237
Filed: 1946-07-12
Abstract: 614,372. Switch contacts. IGRANIC ELECTRIC CO., Ltd. July 12, 1946, No. 20909. Convention date, July 12, 1945. [Class 38 (v)] Indium oxide forms a constituent of approximately 14.5 per cent by weight of a sintered electrical contact. In the highlymagnified contact fragment 5 shown, a base .metal 6 of silver approximately 80 per cent by weight of the contact forms a matrix for a mixture 7 of the indium oxide and a small proportion of a metallic salt such as silver iodide. The contact is moulded by subjecting the powdered constituents to intense heat and pressure. The indium oxide imparts non-welding properties to the contact and the low resistance suits it for D.C. breaks, whilst the silver iodide by volatizing spreads the arc surface, thereby lowering the current density and hence the heating, and also by decomposing counteracts the increase of the contact resistance with use. The base may be of any good conducting material such as silver, silver alloy, copper, nickel, gold. The metallic salt may be silver iodide, silver bromide, silver chloride, cadmium chloride, cadmium sulphate, or the contact may be formed without a metallic salt. The percentage of indium oxide may vary between 7-5 and 21-25. Specification 588,652 is referred to.

Title: Improvements in or relating to patterning mechanism for multi-feed circular knitting machines
Inventor: BURDETT HENRY SIDNEY
IPC: D04B15/74
Filed: 1968-05-03
Abstract: 1,206,225. Knitting-machines. S T I B B E MACHINERY Ltd. 27 May, 1969 [3 May, 1968], No. 20995/68. Heading D1C. A multifeed circular knitting-machine having each needle selectively actuated as the result of the pressing or mispressing of a single reading butt 27 on the end of a presser jack 25 has the presser jacks arranged in groups E, F, Fig. 3 with the single reading butt 27 of the jacks of the group at two a, b or more levels and the stack of rotary selector discs 37 for acting on the single reading butts arranged likewise in groups A, B of two or more so that the full width of the pattern in terms of the needles actuated in the width corresponds with the total number of pattern teeth of the discs of the groups acting on the pressers. The pattern discs 37 may be arranged alternately so that any two adjacent discs control two groups of jacks E, F having reading butts 27 at the corresponding levels. Actuation of the pressers 25 cause an intermediate member 29 to pivot and rock the needle actuating jack 24 out of engagement with the cam engaging the butt on the jack. Consequently the needle is not selected to knit. Only the needles having jacks and pressers which are not operated by the pattern discs are caused to be rendered operative. The lower portion of the pressers have a number of cam engaging butts 28 which when the cams are rendered operative as described in Specification 39958/68 cause the pressers to move up or down so that the single reading butt 27 registers with a different pattern disc and a fresh selection can be achieved. Instead of a single stack of pattern discs, two stacks ES, OS, Fig. 8, may be provided at each feed and the discs in each stack arranged in a wider spacing. The discs of the first stack are spaced at levels intermediate those of the second stack. A first selection SP1 is made by pressers of one group at the first stack OS followed by a second selection SP2 at the second stack ES. In addition the pressers may have reading butts on one group of jacks E arranged at two levels c d and also butts on a second group of jacks F arranged at a third and fourth level a, b, Fig. 9. Selective operation of the pressers under the dictates of the discs according to the butts at the appropriate level on the corresponding groups enables various patterning effects to be achieved. In the case of the provision of two stacks of discs at a feed the discs of both stacks may be at the same levels, the pressers after the first selection being lowered prior to the second selection and then raised again.

Abstract: 336,004. Holman, A. T., and Holman, K. J., and Rule, J. July 9, 1929. Percussive drills.-A drift 32 for enlarging the bores of hollow drill steels and similar articles is attached to an anvil member 7 which carries two anvil blocks 9, 10, the latter being in two parts held together by the bore 12 in the cylinder 4. The whole is mounted on the bar 13 which moves longitudinally on rollers 2, 3. Notches 26, 27 are formed in the bar to engage the rollers and so retain the machine in its rearmost position when subject to vibration. On pulling the handle 20 to the left the drift is brought into contact with the work, and the anvil member is forced into its rearmost position within the cylinder 4. A further pull on the handle moves the tappet sleeve 18 to the left, opening the valve 17. Pressure fluid then enters the cylinder, causing the piston 8 to strike the anvil block 9. Due to the position of the anvil member relative to the cylinder and its parts the return stroke of the piston is cushioned from the anvil block 10. On releasing the handle 20 springs 118 return the tappet sleeve to its central position and the valve 17 is closed, stopping the piston. To withdraw the drift, handle 20 is pushed to the right, first moving the cylinder rearwardly relative to the anvil member, and then depressing the valve 17. The piston now strikes the anvil block 10, its blows on the block 9 being cushioned.
