Title: Improved process and apparatus for arc welding
IPC: C08F2/04
Filed: 1948-06-16
Abstract: 648,638. Uniting by fusion. ARNOLD, J. C. (Lincoln Electric Co.). June 16, 1948, No. 16238. [Class 83 (iv)] In arc welding, a current of high density is applied at one end of the electrode sufficient to raise the electrode tip to melting point substantially instantaneously by resistance heating alone, when it contacts the work. The contact is thus broken and an arc established and the electrode is continuously fed while the current is maintained at the high density. The current density is at least 60,000 amperes per square inch and may be as high as 290,000 amperes per square inch. The electrode wire is fed at speeds greater than 10 feet per minute, up to 50 per minute with a one-sixteenth inch diameter wire. A hand-tool comprises a body 2 with an insulated' holder 2a with a guard screen 2b. The electrode wire W is fed through a flexible tube 1 against a curved deflector and current conductor 3 connected to a supply lead 19. A small hopper 4 for flux has a normally closed trap 5 opened by a hand lever 6. The wire W is fed from a reel 10 by rollers 14 driven through a variable-speed friction cone system by a motor 13. A relay 23 is provided to start the motor as soon as the arc is established, and a press-button 24 is provided for threading the wire W initially. The flux is preferably fed simultaneously with the welding, either intermittently, or continuously when the depth of flux may be used as a guide. The seam width is controlled by the traverse speed, and the operation continues if the tool is stationary. An alternative definition of the current density is that it will melt off a ¢ inch of wire in one second and extinguish the arc. The arc voltage is from 25 to 50 and the arc stream is narrow to give good penetration. In an example a three-sixtyfourth inch wire with a 400 ampere supply at 40 volts and fed at 470 inches per min, deposits 0.23 lb. per min. The tool may be mounted for automatic traversing. It is stated that in operation the resistance heating of the electrode tip is greater than the arc heating.

Title: Package-forming apparatus
IPC: B65B9/02
Filed: 1978-04-26
Abstract: In the apparatus, the containers (2) are first collected to form a group (5) of predetermined number on a layer (7) of cardboard supplied from a magazine (8) and then, together with this layer, they are pushed sideways onto a lifting unit (11). Vertically above the lifting unit (11) there is an auxiliary platform (16) onto which is placed a second layer (22) of cardboard, supplied by a second magazine (23). The platform (16) can open up in order to allow the passage of the containers (2) when the lifting unit (11) rises up and can close up again to hold them when the lifting unit is lowered to pick up another group (5) of containers (2). Each group lifted up is stacked beneath the layer of cardboard (7) of the group lifted previously and is supported by the platform (16) which has in the meantime closed up again. Finally a pusher (25) transfers the stacked groups (5) of containers (2) towards a station where they are wrapped in a heat-shrinkable plastic film (27) wrapper. It is envisaged that the apparatus will be used to package containers of milk having a parallelepipedal shape. <IMAGE>

Title: Improved machine for generating helical grooves
IPC: B23F11/00
Filed: 1941-12-23
Abstract: 631,724. Gear-cutting. REISHAUERWERKZEUGE AKT.-GES. Dec. 23, 1941, No. 16574. Convention date, Dec. 13, 1940. [Class 83 (iii)] In a machine for generating helical grooves such as helically-toothed gears the work-piece 20 is rotated and moved axially past the tool, such as a hob 19, and the additional work rotation in unison with the axial movement is derived from the work slide movement, which acts through change gears and differential gearing to cut a selected stepped series of groove pitches on the work, an additional movement also derived from the work-slide movement being provided for the purpose of obtaining a continuous range of pitches between the steps. The work is driven from the shaft 1 through differential spur gears 2, 5, bevel gears 9, and gears 11. When the work-slide 16 is moved downwards by a hydraulic piston, a rack 24 mounted on the slide drives a pinion shaft 25 which through change-gears 26 rotates the differential casing 6 to apply corresponding rotation to the work. To obtain a continuous adjustment of pitch between the steps obtained by the change-gears a bell-crank lever 18 pivoted to the work slide has one arm pivoted to rack 24 while the other arm engages an adjustable guide 31 so that during the axial work movement the rack is moved relatively to the work-slide by an amount dependent on the angular setting of the guide 31. The difference between the movement of slide 16 and that of rack 24 may be expressed as a percentage of the desired pitch and the adjustment as measured by scale 34 arranged accordingly.

Abstract: 655,185. Forming pellets from sheets of thermoplastic and thermosetting materials. KRIS, R., HARRISON, A. M., and WELWYN PLASTICS, Ltd. June 22, 1948, No. 16729. [Class 87 (ii)] [Also in Group II] A sheet of thermosetting or thermoplastic material is passed between heated, adjustable thicknessing rollers 3, then between a circumferentially-scored, heated roller 13 and a plain roller 12 to score the sheet longitudinally, and finally between an axially-scored, cooled roller 23 and a plain roller 22, to score the sheet transversely. The scored sheet is then broken up into pellets by a rotary beating machine. Feed dogs, see Fig. 4 (not shown), are provided to prevent lateral spread of the material. Scrapers 10, 11, 21, 20 and 27 separate the material from the rollers 3, 3, 12, 13 and 22 respectively. If material sticks to the roller 23, it engages a member 28 which stops the machine. Spring-pressed plungers, see Fig. 6 (not shown), may be used for positively removing the material from the roller 23. The rollers 13 and 23 are mounted in a pivoted frame 14, to facilitate access to the scoring rollers and the material. Spring pressure between the rollers 13, 23 and 12, 22 is so adjusted by a screw 17 that the rollers do not cut right through the material.
