Title: An internal gear finishing machine
IPC: B23F19/06
Filed: 1955-04-26
Abstract: 797,282. Gear - finishing. NATIONAL BROACH & MACHINE CO. April 26, 1955 [June 14, 1954], No. 11972/55. Class 83 (3). A gear-finishing machine comprises a work-spindle 24 which is rotatably driven on a support 22 adjustable about a horizontal-axis at right-angles to the axis of the cutter C. The work W is mounted on a shaft 24 rotated through change-gears and worm-gearing by a motor 26, the drive-shaft 112 extending through a hollow-pivot, about which the work-head 22 is angularly adjustable. The adjustment is made, through worm-gearing and a shaft 84 against a scale S, to enable tapered-gears to be shaved or to tilt the head for insertion of a workpiece mounted on a relatively long shaft. The cutter-head is mounted on a slide 156 which can be advanced, by toggle-means 166, 170 and a handle 176, to a working position determined by an adjustable block 17,8 engaging a wedge-block 177 on the slide. The slide 156 moves on a slide 148 which is advanced, on a vertically-adjustable knee 18, by a screw 144 rotated through a shaft 140 to effect one or more complete reciprocations, with vertical adjustment under the control of dogs 152. The screw 36 for vertically-adjusting the knee 18 may be rotated by a hand wheel 40, or be intermittently fed by means as described in Specification 725,627. Alternatively it may be fed in a continuous movement, without reciprocation of the cutter, to effect a plunge-cut. The cutter C can be turned by a hand wheel 234 to position it as the slide 156 is advanced by the lever 176. It is adjusted axially by a screw 220 and angularly about the centre-point of the cutter by a shaft 194 carrying a worm 196 engaging a segment 200 on an angularly-adjustable slide 182. The adjustment is indicated by a scale or measured accurately by gauges placed between blocks 204, 206 on the. slide 156 and a block 208 depending from the slide 182. Coolant is supplied to the cutting- zone by a motor 46. In a modification, the work-head is moved angularly about its hollowpivot, to and from working position, by a fluid-pressure device and a toggle-linkage. In a further modification, the cutter is rotated instead of the work.

Title: Improvements in the rolling of metal stock
IPC: B21B1/24
Filed: 1957-04-12
Abstract: 800,003. Rolling. CRAMER, H. April 12, 1957 [April 23, 1956], No. 12101/57. Class 83 (4). In a mill for rolling hot metal strip the first stand 3 of a finishing train is arranged behind the reversing stand 2 at a distance d which is less than the final length of the strip after its last pass through the reversing stand. The speed of the reversing stand 2 is synchronized with that of the first finishing stand 3 by a control box 8 so that on the final pass the strip can enter the finishing stands before it leaves the reversing stand. Preferably the distance d is approximately equal to the length of strip after the third from last pass through the roughing stand 2. The strip is finally coiled in a coiler 7.

Title: Improvements in or relating to conveying mechanisms
IPC: B65G13/00
Filed: 1929-04-18
Abstract: 331,017. White, A. E., (Morgan Construction Co.). April 18, 1929, Roller-way conveyers. - Each roller 2 is rotatably mounted in a member 5 which is rotatably mounted in an inclined bearing 14. Each roller has end flanges 12 and projects through an opening 4 in a floor 3. The surface of the floor is inclined at 3<1>, 3<11>, Fig. 3, on each side of the series of rollers. When a member 5 is turned in its bearing, not only does the roller axis assume a skewed relation to its normal position, but it also has one end depressed so that its flange is below the floor and the other end correspondingly elevated. The material. therefore, rides off the rollers into the trough 3<1> or 3<11>. In a modification, the rollers are formed with peripherally-dished surfaces and successive rollers are alternately higher and lower in speed than the delivery speed of the material.

Title: Process for producing l-malic acid anions of l-malic acid or salts of l-malic acid
IPC: C12R1/38
Filed: 1974-03-19
Abstract: Filamentary structures containing encapsulated fumarase are used for the enzymatic preparation of l-malic acid from solutions of fumaric acid salts. The fibres encapsulating the fumarase are obtained from polymers which can form fibres and are selected from esterified, nitrated cellulosics, polyolefins, polymers and copolymers of acrylonitrile, acrylates, methacrylates, vinyl esters, vinyl chloride, vinylidene chloride, styrene, polyamides or polyvinyl butyral, especially polymers of cellulose triacetate. The process makes it possible to achieve the enzymatic hydration of fumaric acid to give l-malic acid with remarkable ease; since the enzyme is immobilised, it can be used more than once and does not contaminate the product.

Title: Improvements relating to the operation of a plurality of adjustable members, more especially applicable to wireless receivers
IPC: H03J3/28
Filed: 1929-04-19
Abstract: 310,050. Savoye, F. April 20, 1928, [Convention date]. Condensers.-An operating device for two or more adjustable members, particularly in wireless receivers, has a reduction gearing which varies both members simultaneously, at the same time superimposing a periodic variation on one member. As shown, the movable vanes 2, 3 of two condensers are mounted on a common shaft 1 passing through a bearing 5 in a panel 4 and operated for coarse adjustment by a knob 12. The stators 6, 7 are supported by bearings 8, 9 which engage at a face 10 and can turn relatively to one another. Fine adjustment is effected by a knob 20 on a shaft 19 which rotates the shaft 1 through reducing gearing 18, 17, 16, 15. The wheel 15 is loosely mounted on the shaft 1 and is engaged by a star spring 22 keyed to the shaft 1 so as to provide a friction drive for the fine adjustment. On the shaft 19 is mounted a crank 3 which rocks the stator 7 by means of a connecting-rod 24. By this means the condenser 7 is given a periodic variation during the small simultaneous adjustment of both condensers due to one revolution of the knob 20, so that the capacitiy of both condensers may be adjusted to the same value in spite of differences in their individual characteristics.

Abstract: 560,039. Spring frames for motor cycles. NORTON MOTORS, Ltd., and FRANKS, E. M. Sept. 11, 1942, No. 12874. [Class 136 (iii)] [Also in Group XXXII] In rear springing for a motor cycle in 'which the load is supported by helical compression springs, the load is applied to each spring through an angularly and axially - movable member engaging between adjacent coils of the spring, means being provided for locking the member in different angular positions. As shown, each end of the wheel spindle is carried by a fork a slidable on a rod b rigidly secured between frame-members c, d and a collar j, working on the screw-threaded upper end of the rod b, has lugs k projecting between adjacent coils of the load - supporting spring f and engaging longitudinal grooves l in a sleeve m enclosing the upper end of the spring. Rotation of the sleeve causes the collar j to rotate and to move along the screwed part of the rod b and the lugs k thus bring one or more coils of the spring into or out of action. The sleeve is locked in position by a gravity catch q, engaging notches or pegs on the upper end of the sleeve. A. spring g absorbs rebound. In order to give a visible external indication of the position of the collar, to ensure that the springs on each side of the wheel are adjusted similarly, an indicator ring r fitted frictionally around the sleeve m is provided with two diametrically-opposed oppnings or windows and a projecting lug t adapted to engage a stop peg u. The arrangement is such that four positions of the collar, angularly spaced by 180 degrees, can be shown, a figure indicating the particular position coming opposite an opening or window as adjustment is made.

A plurality of longitudinal or helical fins are formed on a tube 10, which may be of magnesium alloy, by radially acting tools 11 vibrated at high frequency by vibrators 18 on an annular support 16 and which are moved radially inwardly by hydraulic means. The recesses 15A are formed between adjacent tools. The support 16 or the tube is moved axially continuously or intermittently for forming continuous or discontinuous fins. Helical fins are formed by supporting the workpiece 10 on a mandrel 20 between centres 22, 21 on the movable carriage 23 of a lathe and mounting the tool support 16 on the lathe bed 30. A circular cam roller 26 also mounted on the mandrel 20 has a helical slot 27 co-operating with a fixed follower 28 on the lathe bed whereby as the carriage 23 is advanced the workpiece 10 is rotated.
