Abstract: Apparatus for extruding composite products, especially food products such as simulated bacon slabs having components representing meat and fat, respectively, that replicate the random pattern of natural bacon slabs. The apparatus has an extrusion die member which, in some embodiments, is rotatably mounted for manual or motorized movement from one selected position of adjustability to another selected position of adjustability about a substantially circular path of adjustability that is preferably visually indexed to indicate the extent of any positional adjustment of the extrusion die from time-to-time. The apparatus may include a standard sausage stuffing machine for controlling movement of the extrusion die. In all embodiments of the die, it is independent of the apparatus in which it is adapted to be installed so as to be easily removable and replaceable relative to such apparatus, but need not be rotatable.

Abstract: An archery broadhead has twelve broadhead blade receiving slots to receive a plurality of broadhead blades in selected slots. A variety of different orientations of two blades, three blades, four blades, or more can be used to assemble a desired broadhead. By providing blades of different weights and a selection of different weight points and collars, the archer is given the opportunity to create a broadhead of blade configuration and weight as desired. A spearhead point with only two cutting blades and convex faces between the blades provides improved cutting and penetration of a target.

Abstract: An archery bow stabilizer is made up of a plurality of blocks of a solid resilient material such as a rubber material joined together in end-to-end relationship. Threaded sleeves in each end of each block allow the blocks to be joined together and the joined together blocks to be secured to the handle riser of a bow in normal manner using threaded studs. Usually three to four joined blocks will provide satisfactory stabilization for most bows but more or less blocks may be used when desired. The invention also contemplates stabilizers with rubber or similar resilient material exterior surfaces to eliminate most noise created by the stabilizer during knock-around in the field.

Abstract: Trailer jack attachment assemblies which do not extend below the lowermost frame member of the trailer body so as to avoid increasing obstruction from roads and rough terrain. Attachment is made to the trailer frame without destroying its structural integrity. Cross braces between laterally opposite attachments minimize localized twisting of individual frame members.

Abstract: A method of renewing decorative tassels after they have become unsightly from wearing of an item to which they are attached, particularly shoes wherein the one or more tassels is made up of strands of moisture-absorbent leather or synthetic leather extending integrally side-by-side from a stem base attached to the shoe. The method comprises encasing the tassel, as straightened and rearranged, in a tube length of heat-shrink material; applying moisture to the strands of the tassel; heating the heat-shrink tube along its length to shrink it tightly against the tassel as straightened and rearranged, so as to press it into renewed condition; and removing the shrunken tube from the renewed tassel substantially without disturbing the straightened and rearranged strands thereof.

Abstract: A method of reducing the chance of disease resulting from mononuclear cells in a body attacking desirable cell antigens in the body, such as antigens expressed by normal body cells or desirable engrafted cells, comprises reducing the number of mononuclear cell in the body that are likely to attack such desirable cell antigens. This is done by obtaining cell derived antigens subject to attack by mononuclear cells in the body and also obtaining mononuclear cells to be placed in the body. The mononuclear cells may be from a donor or may be removed from the subject body. The mononuclear cells are reacted, in vitro, with the cell derived antigens, such as by passing the mononuclear cells over a layer of fibroblast cells from the body expressing the desirable antigens, and recovering the mononuclear cells that do not bind to the antigens. These recovered cells are then infused into the body.

Abstract: An apparatus and method for sensing the swelling and shrinking of an elastic member based on movement and the angular changes to the surface of the elastic member between one or more portions of the surface thereof. The apparatus includes first and second parts which cooperate to produce an electrical signal indicative of the angular and distal positioning of the respective parts, with one of the parts preferably being a Hall effect device and the other a magnet. At least one part is mounted on a flexible base which attaches to a first portion of the surface of the elastic member for movement therewith with the other mounted for movement with a second surface portion of the elastic member. The apparatus and method are particularly adapted for use on a male penis and female breast for estimating sexual arousal based on the swelling of such body parts due to engorgement with blood which accompanies sexual arousal.

Abstract: A device for winding a carpet strip into a compact roll for handling and transport winds the carpet strip about a motor powered winding spindle controlled by, for example, a foot pedal, the strip being guided onto the spindle by a pair of selectively spaced apart guiding discs. The rolling machine may be attached to the frame of a sewing station through which the strip is passed to provide a binding tape along an edge of the carpet strip, the strip passing without handling from the sewing machine to the carpet strip rolling machine. Pedal or other controls at the sewing machine permit the operator to control both the rolling device and the sewing machine from this single location.

Abstract: A special tuning point for archery arrows for use in tuning a bow, target shooting, and non-big game hunting has a weight approximately equal to a broadhead selected for use by an archer using and tuning the bow and has a balance point position ahead of the arrow shaft to which the point is secured approximately equal to that of the selected broadhead. The tuning point is secured to the forward end of an arrow shaft substantially identical to that used with the selected broadhead to form a tuning arrow. The tuning arrow is used in tuning the bow. In this manner, the bow is properly tuned for not only the tuning arrow, but also for the arrows with the selected broadhead.

Abstract: An improved stylus assembly for replacing state of the art compressed air powered scribing tools, said stylus stem and point being monolithic and capable of operation indefinitely without failure of the stem, requiring only infrequent sharpening of the scribing tip.

Abstract: A hollow archery arrow shaft has a rearward end portion which is reduced in inside diameter to frictionally receive and hold the mounting shank of a standard nock. This configuration eliminates the need for a bushing in the rearward end of the arrow shaft for accepting the mounting shank of the nock. Reduced arrow weight and better nock positioning and alignment results in faster and more accurate arrow flight. In aluminum arrows, the reduced diameter portion can be formed by swaging the end portion of the arrow shaft to the smaller diameter.
