A method of preparing a light metal alloy containing at least 3% by weight of tin to render it suitable for use in roll-plating steel, wherein the tin-containing light metal alloy in bar, strip or tube form is treated with an alkali metal hydroxide to remove the tin from the surface and zones closely adjacent the surface and wherein the surface is then roughened by etching the surface with an acid, the treated tincontaining light metal alloy being then preplated with pure aluminium or a homogeneous second light metal alloy containing substantially no tin. The pre-plating material extends around the edges of the tin-containing light metal alloy. The prepared material is rollbonded to a steel backing strip which has a roughened surface and has been heated in a protective atmosphere to 550-720 C. The prepared material is heated by contact with the steel in the rolling gap to 400-500 C. The etching step is carried out by using a mixture of nitric and hydrofluoric acid. The roughening of the surface is increased by preceding the etching by treating the surface with an alkali metal hydroxide and also hydrochloric acid. The tin-containing light metal bearing alloy contains 3-35% by weight of tin.

Filed: 1925-02-02
Abstract: 245,614. Marks, E. C. R., (Nonpareil Ma. chine Co.). Feb. 2, 1925. Sheet-separators; pile tables and supports for sheet-feeds; sheet carriers and guides. - Sheets are separated from piles by pneumatic suction devices which move the front edge of the separated sheet into contact with a rotary segment co-operating with a feed roll to complete the separation of the sheet. The pile 5, Fig. 6, rests on a support 6 and is positioned by uprights 1, 2, 3. The front end of the pile is acted on by fingers 8 and by a supporting rod 33 carried by a reciprocating slide 34. When a sheet is to be fed, the fingers 8 are oscillated by crank-mechanism, and the slide 34 is moved to the left to permit the bottom sheets of the pile to drop into contact with a series of suction nozzles 25 on an oscillatory tubular shaft 26, which descends with the bottom sheet adhering while the rest of the sheets are restored bv the fingers 8 to normal position. The partially separated sheet is carried down into the gaps of rotary segments 40, and the front edge of the sheet is engaged by shoulders 42 on the segments and carried into contact with rotary discs 41, mounted in spring.pressed bearings. The sheet is thus gripped and the separation is completed as the discs 41 and segments 40 advance the sheet by the aid of a guide 45 to rollers 46, 47. The discs 41 are fitted, with spring-pressed loose pieces 41d, so that the sheet can slip when gripped by the rollers 46, 47 which are rotated faster than the discs 41. In a modification, Fig. 11, the fingers 8, Fig, 6, are replaced by fingers 55, 56 so arranged and operated that when the fingers 55 release the bottom sheet, the fingers 56 engage the next sheet. The suction device 76 is carried by a tube 77 mounted in a carriage 79, which is reciprocated from a crank oscillated by a reciprocating rack engaging a pinion 82 on the crank-shaft. The tube 77 is rotated as the carriage 79 reciprocates so that the engaged sheet is carried into engagement with rotating segments 115, and is engaged between these and rollers 118 mounted in spring- pressed bearings. Additional spring-pressed rollers 120 mounted in a spring-controlled swing- ing frame 134 are used, and the sheet is advanced by rollers 121, 122, all the rollers being driven from a gear wheel 123 on the shaft 116 of the segments 115. The sheets are guided by flanges 141, 142, on a pivoted guide member 140 which can be swung down out of the way if the papers are jammed. The suction device is connected by a telescopic connection to a suction pump or movable relatively to a seat having passages which nearly but not quite meet. The rotary member is oscillated from a cam by a link

Title: Improvements in and relating to electrical pulse counting arrangements
IPC: H03K25/00
Filed: 1947-02-03
Abstract: 630,374. Counting apparatus. YARBOROUGH, E. H. COOKE-. Feb. 3, 1947, No. 3208, [Class 106 (i)] [Also in Group XL (c)] Pulses applied to a storage device cause it to charge, a counter being operated while charge exists on the device, the charge being neutralized by means operated by the counter. The circuit is particularly adapted for counting random pulses with a counter of appreciable recovery time, the error due to closely occurring pulses being reduced. A positive pulse, applied to capacitor 1, causes diode 2 to conduct, the charge passing through diode 3 at the termination of the pulse to increase the charge on capacitor 4. The valve normally operates with high screen current and very low anode potential, the fall in grid potential causing the screen current to fall and relay 7 to release to start the counter 8 operating. Each time a count is registered contact 9 reverses and extracts a charge from capacitor 4 at least equal to that added over diode 3. At the termination of the pulse train when the counter 8 has caused the charge on capacitor 4 to be reduced sufficiently, the screen current rises, relay 7 re-operates and the counter stops. In a modification described in the Provisional Specification, the storage circuit may comprise a capacitor shunted by a diode, a rise in potential across the capacitor causing a counter circuit to operate.

A blind riveting tool comprises an easilyhandled portion including abutment means for holding a rivet up to the work and deforming - member - engaging means, e.g. mandrel-gripping jaws for setting the rivet, and a separate body portion (resting on the floor) comprising power-operated actuating means, the two portions being interconnected by a flexible cable, e.g. a Bowden cable. The easily-handled portion includes mandrelgripping jaws 135, Fig. 1, operated as described in Specification 693,109. The slidable sleeve 131 containing the jaws carries a pin 147 bridging two links 149; the latter are pivoted by links 153 to the casing 123, and are rocked by the Bowden cable 77 engaging a pin 157. The flexible sleeve 79 for the cable is secured at 163. Normally the stiffness of the cable 77 holds the pin 157 and sleeve 131 in the positions shown in Fig. 1 in which the jaws 135 are open. The separate body portion, Fig. 2, which rests on the floor, includes a shaft 17 driven continuously by an electric motor P, and connected through hypocyclic reduction gearing A and an Oldham coupling 41 with a shaft 25, carrying a splined cam 49. A roller 103, slidable under spring pressure in a fixed housing 109, is normally held out of contact with a groove 99 in the cam by a detent 117. In operation, the stem of a mandrel and rivet assembly is inserted in the jaws 135, Fig. 1, and a latch 145 is actuated as described in Specification 693,109 so that the jaws grip the stem. The rivet is held up to the work by the nose-piece 127 and actuation of a trigger 169 energizes a solenoid 167, Fig. 2, to trip the detent 117 through a link 179 and allow the roller 103 to drop into the cam groove 99. The cam 49 is thereupon moved to the left in, Fig. 2, pulling the core 77 of the Bowden cable which is connected thereto through a sleeve 61 and thrust bearing 57, whereby the links 149 are rocked and the jaws 135 pulled back to set the rivet and break the stem. Return of the cam 49 to the position of Fig. 2 raises the roller 103, release of trigger 169 allowing detent 117 to hold it raised.
