Abstract: Apparatus for making gas-filled filling bodies includes a supply reel for storing a pre-fabricated half-tubular plastic film having an at least partially open border side and being divided into individual pockets by weld seams which extend transversally with respect to a transport direction of the plastic film. Positioned downstream of the reel and receiving the plastic film from the reel is a gas filling device for blowing air into the pockets. Positioned downstream of the gas filling device and receiving the plastic film from the gas filling device is a welding tool for welding the open border side of the plastic film for formation of closed filling bodies. The transport of the film through the apparatus is realized by a drive unit which applies a force upon the plastic film essentially downstream of the gas filling device, as viewed in the transport direction.

Abstract: In a plastic tube (1) for the production of gas filled bodies, with two superimposed sheets, connected in a gas tight manner to each other along a first longitudinal edge thereof, the upper sheet (2) and the lower sheet (3) are welded together in the transverse direction along gas tight welded seams (5a,5b), arranged in pairs at a separation from each other, in order to form inflatable pockets (7), which seams extend from the first longitudinal edge (4) to a point at a predetermined separation from the opposing second longitudinal edge (6). The pockets each present, between the upper sheet and the lower sheet, a gas filling opening (8) which is accessible from the second longitudinal edge. Also proposed are a method for the production of gas filled bodies using such plastic tubes and a device for carrying out said method.

Abstract: A plastic tube is prefabricated for producing gas-filled filling bodies. The tube comprises an upper film and a lower film which are connected together in superposed relationship along both of their longitudinal edges. The upper film is divided in its center by a longitudinal cut, thus forming upstanding flaps on both sides of the cut. The films are also subdivided into individual pockets by weld seams extending in the transverse direction of the tube at a spacing from each other. The tube can be filled by introducing a filling gas under the film flaps, the open ends of the pockets being closed after they have been inflated in that way.

Abstract: The invention concerns a plastic tube (1) which is prefabricated for the production of gas-filled filling bodies. The plastic tube (1) comprises an upper film and a lower film which are in mutually superposed relationship and which are connected together along their two longitudinal edges (4, 6). In that case provided in the upper film is a transverse cut (12) which is preferably cut in at its ends by stampings (10). In addition the upper film and the lower film are subdivided into individual pockets (7) by weld seams extending in the transverse direction and spaced from each other. The plastic tube can be easily filled by injecting a filling gas, wherein after inflation of the pockets (7) the open ends thereof are welded.

Abstract: In a method of fitting successively supplied flat articles such as slide frames into insertion pockets in a receiving case, the pockets are arranged in the receiving case in pluralities in juxtaposed relationship and in succession in rows and are accessible from one side of the receiving case. The upper edge of the pockets is formed by a bar portion which extends over a plurality of pockets in a row and can be pivoted upwardly relative to the side walls of the pockets. The articles are fed in groups to the article-insertion location from a feed direction which is transverse with respect to the direction of transportation movement of the receiving case, with the number of articles supplied in a group in that way corresponding at a maximum to the number of insertion pockets for receiving same. An edge part of the bar portion is first lifted and held in the lifted position and the articles in the group are then pushed under the bar portion which they fully lift up, and into the respective pockets.

Abstract: A process for treating a strip of film material carrying images in a plane to substantially remove a bend therein includes the steps of forceably positioning a portion of the film material having a bend into a common plane with the film image plane, subjecting the film portion to heat to remove the bend and thereafter allowing the heated film portion to cool.

Abstract: A storage pocket arrangement for film material, which can be stored in a file, ring binder or the like, has a plurality of individual pockets in superposed or juxtaposed relationship, in a substantially flat configuration, for accommodating respective film strips therein. The arrangement has a strip portion arranged along an edge thereof, which includes punched holes or the like for storing the pocket arrangement in a file, ring binder or the like.

Abstract: In an apparatus for printing characters on film mounts or slides, a computer-controlled needle printer is provided for printing on the slides as they are moved continuously past the printer. Elastic guide members guide the slides past the printer without interference. The needles of the needle printer are individually triggered in accordance with character data keyboard entered into a programmable memory. A read-only memory contains character data that are transferred to the programmable memory in response to operation of the keyboard. An intermediate memory is included at the keyboard to invert the character data (first in-last out) when the slides are turned around and reentered into the printer for printing characters on the reverse side of the slides. The intermediate memory is responsive to a limit switch that sense the presence of a slot formed in one side of each slide.

Abstract: An apparatus for stacking transparency frames, or other substantially flat articles, comprises a rotating cam body located between a feed-in arrangement and a receivng arrangement. The cam body is synchronized to the movement of the transparency frames on the feed-in arrangement, and guides the frames into a receiving shaft that forms a portion of the receiving arrangement. The rotating cam body provides continuous guidance to the transparency frames during movement between the feed-in and receiving arrangements. As a result, breakdowns during stacking are minimized. In one embodiment, the receiving arrangement is disposed transversely with respect to the feed-in arrangement. The cam body comprises a pair of cam discs having a circular sector configuraion. The arc length of the sector is synchronized to the spacing between the transparency frames on the feed-in arrangement. In a second embodiment, the feed-in arrangement and receiving arrangement are located in line to each other.

Abstract: An apparatus for dispensing individual planar, non-circular, uniform, articles, such as image projection slides, slide mounts or the like, from a stack of such articles, comprises a delivery shaft containing an aperture having a cross-section shaped to receive the stacked articles. A dispensing arrangement, located below the shaft, includes a rotary valve supported by a base member. The rotary valve and base member each contains an aperture corresponding in shape to, and coaxial with, the delivery shaft aperture. The apertures contained respectively in the delivery shaft and base member are angularly displaced relative to each other such that a stack of articles, placed in the shaft is supported by portions of the base member exposed through the shaft aperture. The rotary valve has a thicknesss less than or equal to the thickness of each of the articles, and is rotatable by means of a lever arm for orientation of the rotary valve aperture with either the delivery shaft aperture or base member aperture.
