Title: Improvements relating to tray handling apparatus for confectionery manufacture
IPC: A23G7/00
Filed: 1935-06-01
Abstract: 457,772. Feeding trays from stacks. NATIONAL EQUIPMENT CO., 3640, Main Street, Springfield, Massachusetts, U.S.A. June 1, 1935, No. 15996. Convention date, July 19, 1934. [Class 117] [See also Group V] In apparatus for separating confections from a starch &c. matrix, the trays of starch are fed successively from the bottom of a stack, passed through the apparatus adjacent the floor, and restacked. The trays T run on rollers 42 attached to angle irons 40. To remove the bottom tray, the last but one is engaged and lifted by fingers 49 pivoted on vertically reciprocating slides 48. The fingers carry a pin 52 which engages a stop 58 on the down stroke and a plate 56 on the upstroke so as to oscillate the finger clear of the bottom tray. The stacks may be positioned manually on the rollers 42 but this is preferably done automatically. This feed mechanism comprises a lazy-tongs 68 mounted on a frame 60. A roller 92 carried by a spring controlled arm 90 bears against the side of the trays. When the last tray is removed, the arm swings sideways and thereby engages a clutch on the shaft 76 which operates the lazy-tongs through a cam and levers 73. The tongs carry gripper bars 80 which engage the end of a fresh stack and draw it onto the rollers 42. During this operation the stop 56 is moved to one side by the roller 92 so that the finger 49 no longer engages the trays. The slide 48 is continuously reciprocated by cam mechanism from the shaft 76. When the bottom tray is released from the stack it is continuously advanced along rails 129 by paddles carried on an endless chain through the apparatus. The trays are restacked by a similar mechanism to the feed device. Specification 457,765, [Group V], is referred to.

Title: Improvements in variable velocity gearing
IPC: B65B65/02
Filed: 1925-06-22
Abstract: 257,371. Molins, W. E. June 22, 1925. Packeting by wrapping-up.-In a machine, such, for instance as the cigarette-wrapping machine described in Specification 165,891, rotary motion is transmitted between shafts 15, 12 with cyclically varying speed by means of a chain or endless flexible element 16, which suffers periodic changes in its path. The active part of the chain 16 between driving and driven sprockets 17, 14 passes over an idle eccentric sprocket 23, which is constrained to rotate, and imparts the periodic changes in speed to the chain part upon the sprocket 14. Slack in the return part of the chain is taken up automatically by a jockey 18 pulled by a spring 21. The shaft 12 through bevel gearing drives one of a pair of rollers 5 between which a web of wrapping material 4 is fed. The web 4 passes down through a slot 3 in the bed 1 of the machine, and is adapted to be cut when moving slowest as a batch of cigarettes moved along the bed 1 by a conveyer meets the web.

Title: Improvements in or relating to adhesives for attaching copper foils to other objects
IPC: C09J109/02
Filed: 1958-05-23
Abstract: A thermosetting adhesive for attaching copper foil to another object contains a copolymer of butadiene and acrylonitrile, a phenol-aldehyde type resin and an aliphatic monocarboxylic, or hydroxyl or chlorine substituted monocarboxylic, acid, containing 1-4 carbon atoms, e.g. formic, acetic, lactic, monochloracetic, propionic or butyric acid.

Abstract: 868,223. Rollers. MOUNT HOPE MACHINERY S.A. May 15, 1959, No. 16673/59. Class 42 (2). [Also in Group XVI]  A roll of adjustable longitudinal curvature comprises an initially rigid axle which is longitudinally slitted to provide two or more separated relatively long axle portions which terminate at their inner ends in a continuous unslit portion and which are otherwise relatively movable for introducing longitudinal curvature in the axle, means at the split end of the axle for effecting controlled relative movements of the said axle portions and means for maintaining a selected relationship of the separate axle portions with a predetermined curvature in the axle. In the arrangement shown, roll 10 is rotatable on axle 12 by ball bearing units 14. The axle 12 is slit longitudinally at 38 from its left-hand end, throughout the major portion of its length, to provide two axle portions 121 and 1211 and an unslit solid portion 40. The portion 12<SP>1</SP> is secured to a member 44 and the portion 1211 is secured to a member 48. By the screw and bolt arrangement shown at the left-hand end of axle 12 the portion 12<SP>11</SP> can be forcibly moved relative to the portion 121 thereby introducing longitudinal curvature into the axle 12. When the desired curvature has been produced, the parts can be locked in the selected position. The ends of the axle 12 are mounted in suitable bearing members 34 and 76. The slit 38 may be made by a suitable saw blade and the two axle portions 121 and 1211 are preferably maintained in their slightly spaced relationship by a strip 96 of suitable material loosely inserted. A second embodiment shows two parallel slits in the axle. Specifications 736,674 and 754,967 are referred to.

In arc welding or coating a hard, carboncontaining, metal deposit is obtained by dip transfer arc welding using a short-circuiting arc to which is fed a gaseous carbon compound which decomposes under the action of the arc to liberate finely-divided carbon which enters the weld deposit. A mild steel electrode 10 containing manganese titanium and silicon as deoxidizers is used. A hydrocarbon gas, e.g. methane, propane, butane, acetylene or coal gas, is fed to the arc through a tube 15. A sleeve 13 serves to retain hydrogen formed by decomposition of the hydrocarbon gas, and the hydrogen acts as a shielding gas. Specification 901,333 is referred to.

Abstract: 624,548. Loose-leaf binders. GILBERT & SONS, Ltd., A., and GILBERT, A. June 26, 1947, No. 16905. Addition to 591,879. [Class 146 (i)]  Thong tensioning mechanism for a loose leaf thong binder comprises a screw 10 and nut 9 mechanism for adjusting the bar 7 tensioning the thongs 4, 5 of the binder operable by a lever 20, housed in a recess 19 in the outer edge of the binder cover 1, captively and drivingly connected to the screw 10, the lever 20 having a handle 25 movable into either a stowed position or into a position, shown in dotted lines, in which it extends outwardly beyond the lever and the binder cover and in which the lever may be rotated by the handle. The handle comprises a pin 25 with a head 26 and is held in either position by a spring pressed ball 32 which enters one of the slots 30, 31. In the stowed position the pin 25 enters into a hole 28 or 28a in a block 29 and thus serves to lock the lever 20 against unintentional rotation. The lever 20 has a boss 21 spring urged at 23 and formed with teeth 22 to clutch with similar teeth on a sleeve 15 which is connected to the plain end 14 of the screw 10 by a pin 16 and slot 24 connection. With this arrangement the lever 20 may, if misaligned with the recess 19 at the end of a tensioning operation, be pulled out and realigned. When the thongs or stack of leaves in the binder are sufficiently resilient to allow such final realignment, the lever 20 may be formed integral with the sleeve 15. A lock may be provided for the pin 25 in the stowed position. According to the Provisional Specification the pin 25 is held in stowed and withdrawn positions by a spring cup at the end of the pin frictionally engaging respectively the wall of the hole 28 and a recess in the operating lever.
