Abstract: A catheter assembly including a plastic tube having a cup-shaped bulb at one end and which is oval in cross section. The walls of the bulb are thicker than the remainder of the tube and a hub is molded about the bulb both interiorly and exteriorly thereof. The bulb is formed by placing the tube on a mandrel, which extends from a mandrel carrier, and thereafter placing the carrier on a base so that the upper end of the tube and mandrel extend through a slot and into a heating cavity defined by a housing. The upper end of the tube is subjected to radiant heat on opposite sides thereof to heat the circumference of the tube unevenly to form and define the cup-shaped bulb. The upper end of the tube is heated to a temperature close to its melting point.

Abstract: Strips of photographic film are processed through a film developing machine which transports the film by means of rollers. Curling of the film around the rollers of the machine is avoided even though no separate leader is attached to the film.This is accomplished by first inserting one end of the film strip into a device which has an open slot defined by a pair of platens which face each other. At least one platen is heated and at least one platen has corrugations in its slot-defining surface. Provisions are made for responding to insertion of the strip into the slot to close the platens upon the inserted strip, and maintaining these platens so closed for a length of time sufficient to impress the platen corrugations into the film. The slot is then reopened, the strip is withdrawn, and inserted into the nip of the input rollers to the developing machine.Specific embodiments of the corrugating device are also taught.

Abstract: A clamping frame for use in plastic forming apparatus which includes a plurality of tubular elements joined together to define an opening over which a sheet of plastic material is mounted with the edges of the plastic sheet being held against supporting surfaces of the tubular elements by clamps. Each tubular element is formed of a thermally conductive material and includes an interiorly disposed heating element located adjacent the supporting surfaces of the tubular element. The tubular elements include a plurality of interconnections to permit selective positioning of the tubular elements with respect to one another for varying the size of the opening defined thereby, and these interconnections also electrically connect the heating elements within the tubular elements at all adjusted positions thereof to form a closed electrical circuit which may be connected to an electrical source whereby the edges of the plastic sheet between the clamps and the tubular element supporting surfaces may be heated.

Abstract: A machine for forming sealing liners of thermoplastic materials in crowns, which includes a crown carrier and a press drum. Crowns are disposed on the crown carrier and are directed to the press drum by a transfer plate that directs the crowns from the carrier to the drum. The molding of the plastic liner takes place only on the press drum.

Abstract: A process and mechanism for the dry screen forming of fibers to attain a dispersion in air of substantially individual fibers from which a fibrous sheet is formed. Fibrous nits, pills and flocs are removed from the dispersion by rolling the nits, pills and the like into elongated shapes as they pass a fiber screening member and carrying the elongated fibrous bodies from the dispersion of fibers and away from the sheet forming area for the fibers. The mechanism includes a fiber screening member, a fiber receiving member on which the sheet is formed and a foraminous member which rolls the nits, pills and the like between it and the fiber screening member as the air dispersion of fibers passes toward the fiber receiving member.

Abstract: A series-connected business form is adapted to be fed through the printing means of a business machine and includes a continuous pair of superimposed outer webs each having a row of spaced superimposed feed holes extending along at least one marginal edge thereof for engagement with the feed means of the business machine so that the form may be thereby advanced into and past the printing means. At least one intermediate web is disposed between the outer webs with transfer material lying on opposite sides of such intermediate web, and the intermediate web is secured to only one of the outer webs.

Abstract: A spray spinning nozzle for producing a substantially continuous filament from a molten synthetic resinous material includes a nozzle with a removable orifice from which a filament of molten material is emitted and a gas attenuation assembly which is laterally removable from the nozzle. The attenuation assembly includes at least three gas jets spaced about and radially close to the nozzle axis for emitting parallel high velocity jets. Drag forces produced by the gas jets attenuate the filament to a thin diameter.The resulting filament has a comparatively narrow range of diameter variation.

Abstract: A method and apparatus are provided for shredding and dry-defibrating compressed cellulose pulp, and depositing the resulting fibrous material on a foraminous support to form a batt of relatively uniform density while controlling the feed of cellulose pulp material through the shredding and dry-defibrating operations to the foraminous support according to the output rate of the batt-forming operation, to ensure a relatively uniform density in the batt withdrawn from the foraminous support.

Abstract: Segments for briquetting and compacting rolls which include seats in the roll core and means for clamping the segments in place. The segments define side walls which are in facing relationship when the segments are assembled with the roll core. The side walls each define a groove and a sealing profile in the form of a rod of ductile material is positioned between opposed grooves. When the segments are clamped in place, the profiles are compressed and plastically deformed whereby an impenetrable barrier to the passage of particles between and beneath the segments is provided.

Abstract: An apparatus for the manufacture of multilayer articles has a plurality of female dies mounted in a rotary disc. A plurality of feeding devices equal in number to the number of layers in the articles to be manufactured is distributed about the rotary disc. Each feeding device admits a quantity of material into the female dies as these travel by. A compressing device is arranged downstream of each feeding device as seen in the direction of movement of the female dies. The compressing devices compress the material admitted into the female dies by the respective feeding devices and also cause the various layers of material to adhere to one another. When the required number of layers has been formed, the resulting article is ejected from the respective female die. One or more of the feeding devices is movable to an inoperative position in which it is unable to feed the female dies. This movement may be effected while the female dies rotate.

Abstract: An apparatus useful in manufacturing a continuously extruded running length of construction paneling from continuous flow material sources. The material distribution system, operating in concert with intermittent advance motions of a material conveyor, provides even layer material distribution from the continuous flow sources.
