Completely disposable cooking apparatus for filling and decorating of foods

A completely disposable cooking apparatus used for filling and decorating of foods, that is a one-piece disposable construction, comprising a one-piece, funnel-shaped bag with a soft side wall, having an open first end at the “top” or wider end of the funnel through which food material can be inserted into the bag and a closed second end at the “bottom” or narrow end of the funnel, with an integral, malleable, conical shaped, discharge orifice (also sometimes referred to as a nozzle or a tip). The orifice has serrations or ridges extending inwardly from the internal wall of the orifice, running longitudinally or parallel to the cone axis for all or a part of the length of the orifice. The orifice can either be initially closed or manufactured with a small opening or hole. The orifice is made of a material so that it is capable of being cut at any point along its longitudinal axis to yield an exit opening or hole with a desired size. Regardless of the point of cut, i.e., regardless of the size of the hole or opening, the inwardly extending serrations or ridges that remain after the cut insure that the material is “treated” as it is expelled from the bag through the orifice. While the orifice is capable of “treating” the material as it is discharged from the bag, the orifice is also either: (a) elastic or flexible enough in order to allow the hole or opening in the orifice to expand to pass “clogs” or “lumps” and then return to its original shape; or (b) supple or deformable enough in order to allow the orifice to be compressed or collapsed “upstream” of the hole or opening so that the “clogs” or “lumps” can be broken up and then passed through the hole or opening when the orifice returns to its original shape.

Mandrel for making elastomeric articles

A one-piece mandrel for making elastomeric articles by a dipping process has a one-piece body which includes at least one opening extending therethrough. A split extends from the opening through a cross-section of the one-piece body. At least a portion of the body adjacent the split is formed of an elastically resilient material to allow the split to open for removal of the elastomeric article after formation, and to cause the split to self-close after removal of the article from the mandrel. Closure of the split forms a substantially continuous molding surface in the immediately vicinity of the split. Proper alignment of the mating surfaces of the split is assured by irregular (non-planar) design of the split surfaces, or by use of an alignment element embedded in the mandrel. In embodiments where a ferro-magnetic alignment element is used, a separate magnetized element may also be embedded in the mandrel to assist in holding the split closed during the dipping process. If necessary or desired, both elements may be magnetized.

Method of making plural component fibers

A method for extruding a wide variety of plural-component fiber configurations in a spin pack utilizes one or more disposable distributor plates in which distributor flow paths are etched on one or both sides to distribute the polymer components to appropriate spinneret inlet hole locations. The etching process permits the distribution paths to be sufficiently small to facilitate issuing multiple discrete polymer component streams axially into each spinneret orifice inlet hole, whereby the resulting extruded fiber can be made up of at least one hundred side-by-side sub-fibers. If the adjacent sub-fibers are weakly bonded, they can be readily separated by agitation to significantly increase the effective yield from the spin pack and provide very fine and uniform fibers.

Process of making multiple mono-component fiber

An apparatus for extruding a wide variety of plural-component and mixed monocomponent fiber configurations in a spin pack which utilizes one or more disposable distributor plates in which distribution flow paths are formed on one or both sides to distribute the polymer components to appropriate spinneret inlet hole locations. The etching process, itself inexpensive as compared to drilling, milling, reaming, etc., permits very thin metal plates to be employed, rendering the fabrication expense for the plates small, relative to the remainder of the spin pack, as to justify discarding or disposing of the plates rather than periodically cleaning them. The etching process also permits the etched distribution paths to be small and densely packed, whereby the spinneret orifices can be more densely packed in the spinneret and staggered as between rows and columns so as to increase the fiber yield per given spinneret surface area. The etching process also permits the distribution paths to be sufficiently small to facilitate issuing multiple discrete polymer component streams axially into each spinneret orifice inlet hole, whereby the resulting extruded fiber can be made up of at least one hundred side-by-side sub-fibers. If the adjacent sub-fibers are weakly bonded, they can be readily separated by agitation or dissolution to significantly increase the effective yield from the spin pack and provide very fine and uniform fibers. Importantly, these product advantages are achieved because of the etched disposable distribution plate which reduces initial and maintenance costs and is selectively replaceable to permit differently configured fibers to be fabricated from the same spin pack assembly.

Graphite spiral packing for stuffing box and method for manufacturing the same

GRAPHITE SPIRAL PACKING FOR STUFFING BOX AND METHOD FOR MANUFACTURING THE SAME ABSTRACT OF THE DISCLOSURE A helical spacer, e.g. made of stiffly flexible nylon and having flat axially-presented surfaces, is slid onto a cylindrical mandrel, e.g. a die inside body. Flexible corrugated ribbon of expanded graphite is helically wound onto the mandrel between turns of the spacer. This assembly is placed in a tubular die outside body and tubular punches are run into the die outside body, and moved axially towards one another telescopically of the mandrel. The punches, engaging opposite turns at ends of spacer axially compress and radially expand the helix of graphite, raising its density and producing a product which, in transverse cross-section, closely resembles conventional pre-formed stuffing box packing rings made of the same ribbon starting material. The helical graphite packing stock is disassembled from the spacer and mandrel by rotation, and supplied to the trade. In use, some of the stock is telescoped onto a valve stem, or a mandrel of the same diameter as the valve stem, and cut to length, e.g. using a pen knife. In this way, one stock of packing material can serve valve stems of a range of sizes.
