Abstract: Apparatus for splicing ends of a sheave insert material in which the ends of a premeasured length of an elastic, thermoset sheave insert material are laminated together in a special splicing jig for fabricating a unitized insert loop, which is subsequently stretched around a sheave into a preformed insert receiving slot along the circumference thereof. The jig holds the ends of the premeasured length of insert material in alignment as a heated mold, included therein, fits snugly around the ends and applies heat to the joint therebetween, into which the insert material, in liquid form, has been inserted to join the ends. The heat thus applied to the joint accelerates the curing of the liquid into the same consistency as the insert; thereby producing a unitized bond between the ends by which the unitized loop is thus formed.

The container is further provided with at least one internal mixing arm constituting a support for the end of the feed screw located inside the container.

Abstract: A method of applying a bag to an aerosol type container wherein the product bag is formed of a stretchable material. An upper part of the product bag is first positioned on a tool, after which the product bag is inserted into the can until the upper part becomes seated on the curl which defines a valve cup receiving opening. Then the tool is actuated to effect a radial outward stretching and deformation of the bag upper part with the bag upper part being formed about the curl and thus secured in place relative to the curl. The tool is then removed, the product bag filled with the product, and the customary valve cup positioned.

Abstract: This invention pertains to a method for thermoforming thin-walled plastics articles from an elongated polyolefin web which is manufactured so as to have minimum orientation so that it will expand lengthwise and widthwise when passed through a heating zone prior to thermoforming, which method comprises moving the web both laterally and longitudinally in a co-ordinated manner whereby the normal inclination of the web to sag because of the longitudinal and lateral expansion of the web due to heating is effectively eliminated.

Abstract: A process for the production of seals between surfaces operating at elevated temperatures is disclosed wherein a vulcanizable elastomer mixture is vulcanized by the heat transferred from the surfaces, and by the pressure created by adjustment of the space between the surfaces. In the invention, spacers are arranged between the surfaces to determine the final position thereof and hence the thickness of the seals and the pressure resistance of the spacers is higher than that of the elastomer mixture before or during vulcanization.

Abstract: Machines and process for making in a continuous operation a prestressed glass reinforced, thermally insulating panel, structurally stiff, and totally impervious, of indefinite length and with a cross-section shaped as an elongated parallelogram.Steps for manufacture include making the surface of the panel out of a tubular envelope of knitted or woven glass fabric, stretched over a special holding frame, to give it the desired parallelogram shape. Fastened by a continuous knitting process to the opposite faces of the glass fabric envelope, other glass fibers are stretched inside the envelope and arranged according to three principal directions, all of them oblique with respect to the panel faces. The glass fabric envelope is then coated with a plastic resin to make it impervious to gas and covered on one face at least with a metal liner. This liner, made of cryogenic alloy, has its edges upturned and folded, so as to be fastened to the glass reinforced plastic envelope.

Abstract: Using a highly flowable silicone putty which can be combined with catalysts to set, dentures can be repaired and modified by flowing the putty onto the dentures, allowing it to set while in intimate contact therewith, removing the dentures from the set putty for effecting changes, and subsequently reinserting the dentures in the set putty to effect any necessary changes, modifications or repairs. Prior art practices often used dental stone which had to be chipped away from the dentures when effecting repair or modification.

Abstract: Method for making a filter which comprises a plurality of closely juxtaposed tubes made of a filter material and packed tightly in a tubular envelope. Both ends of the tubes are initially closed. The envelope with the tubes is then dipped to a small depth into a hardenable substance, e.g. latex, which fills the gaps between the tubes and on hardening forms a solid bottom on the envelope. A small length of the envelope and tubes is then severed to open one end of the tubes.

Abstract: An absolute-coded angular position indicator coupled to the shiftable one of two mold-clamping plates, produces a position signal indicating the position of the shiftable plate. This signal is applied to one input of a subtractor, whose output signal is displayed on a numerical display. The subtracting input of the subtractor receives a corrective signal from a manually set decades switch arrangement. When no mold is present between the clamping plates and the latter are pressed into direct contact with each other, the displayed numerical value is zero. When a mold is clamped between the plates, an non-zero value is displayed, and the set-up technician sets the decades switch arrangement to the displayed value. As a result the displayed value goes to zero. The output signal of the subtractor is furnished to control elements which must control machine operations in dependence upon the height of the particular mold being employed.

Abstract: Method for making a collagen sponge including the following steps. Native collagen form of fibrillar protein is comminuted and homogenized in an acid environment; noncollagenous material is removed and residual collagen is mixed with water the pH of the resulting slurry is adjusted to 4.5 to 5.0 by the addition of acetic acid; gluteraldehyde is then added and the slurry poured into molds and frozen at approximately -10.degree. centigrade for approximately 20 hours. The frozen mass is then thawed, washed, and immersed in a wash of pH 8 to 9 for approximately 2 hours at 20.degree. centigrade. Sufficient reducing agent is added to the wash to create excess reducing equivalents. The sponge is then immersed in a buffer solution of pH 4 to 5 for a time sufficient to equilibrate to uniform pH. The sponge formed by the above method is then moistended and self-administered in the upper vault of the vagina proximal to the cervix. The sponge is then retained for a desired period, usually several days to one month.

The lower belt conveyor has a greater length than the upper belt conveyor so that the end of the lower conveyor projects beyond the corresponding end of the upper conveyor. Chilled sausage links are conveyed upwardly by an elevator and deposited on the projecting end of the lower conveyor and passed between the belts. As the sausage links pass between the belts, they are rotated to thereby straighten the links.

Abstract: A tube of thermoplastic netting is drawn through a work station in a radially collapsed, condensed condition. At the work station, the netting is angularly twisted to rope-like form, to increase its bulk density and, in such condition, is drawn between the die and platen of an ultrasonic welding horn. Periodically, the die and platen momentarily bear against a succeeding short length of the twisted, condensed rope-like form making a fused seal nugget integrating all strands of the netting at that site. The resulting product may be a long length of such tubing, having such a seal every so often, or a plurality of bags formed from the intermediate product by making one transverse cut through the netting tube beside each seal nugget.

The casting is made in defined stages.

Abstract: The walls which form a packing container are made from an extruded polystyrene foam plastic material which is stiffened along variously positioned rectilinear zones in the surface by effecting an increase in thickness of the plastic along those zones. The foamed plastic material is initially of uniform thickness during formation of the container but those zones of the walls which are to be thickened have a higher cell density factor than the remaining portions of the walls and hence a higher latent expansion capacity which, after the container has been formed, is released by heating to such an extent that the cell walls soften and are expanded by the increased gas pressure within them. The foamed plastic packing material is formed by extrusion through a die and is of uniform thickness. The desired zones of higher density are established in the material by subjecting those zones to a cooling operation.
