Title: Coil stock holding and feeding device
IPC: B21C47/34
Filed: 1948-12-30
Abstract: 667,569. Feeding webs. HALLER, J. Dec. 30, 1948 [Dec. 31, 1947], No. 33530/48. Class 100 (i). [Also in Groups XXII, XXIV and XXIX] A coil stock holding and feeding device for a sheet material working machine, such as a punching, stamping or shearing machine, comprises a rotatable stockholder or reel 10 driven by a fluid-pressure motor to unreel the stock 11, a pressure-fluid source 58 operatively connected to a moving part of the machine and a valve 95 engaging the stock between the reel and the machine to control the supply of fluid to the motor 112 in accordance with the slackness of the stock. In a punching machine, an arm 26 on the punch platen 22 is connected by a pin-and-slot connection 28 to a lever 34 loosely mounted on a rock-shaft 39 by which the machine feed mechanism 12 is driven. The oscillation of the lever is transmitted to the rock shaft by its engagement with adjustable studs 47 and to a hydraulic piston 58 by a ball-head connection 54. Movement of the piston 58 (see Group XXIX) is transmitted by the fluid in a pipe 88 to a spring-loaded ram 112 connected to a rack 125 engageable with a gear 134 on the reel shaft. The connection between the ram and the rack comprises a slide 118 having a pair of pins 122 engaging inclined slots 124 in the rack and a pair of pads 128 are pressed by a U-spring 131 against the rack to retard its movement with respect to the slide on the initial movement of the ram so that, on the upstroke, the pins and slots move the rack laterally into engagement with the gear 134 and, on the return stroke, withdraw it from the gear. When the stock becomes slack, the valve 95 inserted in the fluid line is almost closed by a lever 106 having a roller 107 bearing on the stock, so reducing the rate of unreeling. In a modification, the piston 58 may be operated directly from the punch platen and the rack 125 may be replaced by a yoke 170, Fig. 11, pivoted at 169 on a link 167 pivoted to the ram rod and having a pair of rollers 174, 175 which, on the up stroke, grip on either side of a flange 177 fitted on the reel or formed on a drum secured to the reel shaft.

Abstract: 1,260,255. Bonding together battery components. ACCUMULATORENFABRIK SONNENSCHEIN G.m.b.H. 15 July, 1970 [17 July, 1969], No. 34380/70. Heading H1B. A leak-proof bond between battery components is made by arranging the components in their relative positions but with a cavity between the surfaces to be bonded and maintaining them in this position whilst injecting a composition of a softened thermoplastic and a foaming agent into the cavity and allowing it to expand to a closed-cell foam and solidify. The thermoplastic may be softened by heating whilst maintaining it under pressure to prevent premature foaming. In a particular embodiment, Fig. 1, a single cell accumulator comprises negative plates D and positive plates B which are joined by strap C to lead terminal 6. Cover 3 is of polypropylene and provides cavities 4 and 5 for thermoplastic material to bond the cover to the base and the terminal to the cover. Mould plate 7, of aluminium, closes the cavities whilst providing holes 8<SP>1</SP> for injection of the thermoplastic. It is removed after the thermoplastic has foamed and solidified. In Figs. 2 and 3 (not shown) the arrangement is similar but the cover is a different shape. Fig. 4 shows a 2 cell accumulator in which cover 23 has a peripheral cavity 24 for bonding the cover to the base and a flange 30 defining a cavity 27 for bonding the cover to inter-cell connector 29 and inter-cell partition 26. In Fig. 6 (not shown) the arrangement is similar but flange 30 is omitted and the cavity is recessed in the cover. Fig. 5 shows a terminal 32 with a metal cap 34 positioned in a cavity 37 for bonding it to the cover. In Fig. 7 inter-cell connector 40 is bonded to partition 42 by thermoplastic material injected into a cavity defined by mould pieces 43 and 43<SP>1</SP> and plate straps 44.

Title: Device for observing rectilineally or approximately rectilineally moving paper or fabric webs
IPC: B41F33/02
Filed: 1935-12-12
Abstract: 453,985. Feeding webs; optical apparatus. MASCHINENFABRIK AUGSBURG-NURNBERG AKT.-GES., 7, Stadtbachstrasse, Augsburg, Germany. Dec. 12, 1935, No. 34534. Convention date, Dec. 14, 1934. [Class 100 (i)] [See also Group XX] In a device for observing marks, such as registration marks, on rectilinearly moved paper or fabric webs by means of a mirror which is moved in such a manner corresponding to the movement of the web that the direction and position of the recurrent reflected beam remains always the same in any position of the moved web for a definite period of time, after the lapse of which the mirror returns to its initial position for the purpose of following the next following mark, means are provided for adjusting the observation device parallel to the plane of the web in order to bring the device to any desired point on the web. For this purpose, the device 33 can be adjusted horizontally of the web 3 by mounting it in engagement with a screw-threaded horizontal rod which can be rotated by a handle 34, while for effecting the vertical adjustment of the device relatively to the web, two web-guide rollers 20, 21 may be adjusted in the vertical direction by a handwheel 39. The observation device consists of a pivotally-mounted mirror 6, which is oscillated so as to follow a registration mark on the web and reflect an image of the mark to the eye of an observer 7 who sees the image reflected from a stationary mirror 22, a quick return of the mirror 6 to its initial position being effected when this reaches the end of its forward movement in the direction of the movement of web. This forward movement of the mirror may be produced by a helical surface on a rotary shaft which is engaged by a lever carried by the mirror 6, the return movement being effected by a spring when the lever reaches the end of the helical surface. Alternatively, the mirror may be oscillated by a suitably shaped cam which is engaged by a spring-pressed lever carried by the mirror. When applied to multi-colour printing, the register of the printing-cylinders I, II, III is observed with the aid of the observation device 33, and within reach of the observer are located hand-wheels 23, 24 which are used to adjust the register of the two printing-sets II, III when necessary, by adjusting the position of web-guide rollers 29, 30, which can pivot about the axes of further guide rollers 31, 33. Specification 439,803 is referred to.
