Abstract: An image altering apparatus which provides confidential viewing of a video display by means of time multiplexing the fundamental display image with a color-inverted image thereof on a pixel-by-pixel basis. Electronic circuitry and/or software are utilized to modify the fundamental image signal by time multiplexing its color data components with corresponding inverse color data components to generate a compound image signal which is representative of a substantially featureless image. Different multiplexing sequences of color data components and inverse color data components may be utilized at varying duty cycles to generate a compound image which is highly confidential and secure from unauthorized viewing.

Abstract: An ambidextrous protective hand covering monolithically formed from a heat/cold resistant flexible silicone material, the opposing interior and exterior surfaces of which each include a plurality of integrally-formed raised nodules that are positionally off-set relative to one another with non-aligning transverse axes. The positionally off-set exterior and interior nodules act to oppose thermal conductivity and provide an effective thermal barrier so as to protect the hand and wrist during handling of articles of differing or uncomfortable temperatures. Optionally, the formulation of the heat/cold resistant material may be chemically enhanced to provide a thermal luminescent change in color of the hand protective covering upon detection of excessive hot/cold temperatures.

Abstract: A method of producing an adhesively closable data disk holder having of a pair of heat-sealable plastic panels fused together to form an interior pocket with an opening thereto, wherein an additional adhesive layer is fused to the inner surface of one of the holder panels adjacent the opening thereof to facilitate adhesive closure of the opening without the use of an overlying flap. The adhesive layer is constructed of a thin panel of compatibly heat-sealable plastic material, one surface of which carries a pressure sensitive adhesive over which an adhesive release strip is disposed. The adhesive layer is disposed between the outer holder panels so that the adhesive release strip insulates against fusion to its adjacent panel, as the opposing non-adhesive surface of the adhesive layer is heat-sealed to its adjacent holder panel. The process results in a data disk holder having a substantially uniform thickness throughout which is particularly beneficial when used in a bindery process.

Abstract: An elongated light fixture configured to create patterns of light saturation which is free of shadows and spots and provides a more uniform light distribution while effecting a substantial saving in energy costs when a plurality thereof are disposed at prescribed locations and elevations. In addition, such a plurality of light fixtures will produce a higher ratio of vertical to horizontal illuminance where vertical surfaces are needed to be amply lighted. The elongated fixture is characterized by its U-shaped cross-sectional configuration which has an interior light-reflective surface comprised of a plurality of elongated parallel panels which are interconnected and extend at a prescribed angle to each other. The fixtures are also claimed in combination with a hybrid magnetic-electronic ballast to provide the above advantages.

Abstract: A multipurpose cinch cleat and method of securing a line thereto with maximum simplicity, to prevent longitudinal movement of the line relative to the cleat in one direction, or if desired, in both directions. The cleat includes an elongated support having a cantilevered post with a free end extending outwardly therefrom, the support having opposite end portions which are fixedly mounted upon a supporting surface with the support being spaced from therefrom. Securing a line to the cleat includes passing the line around one side of the post to create opposing right and left-hand line segments; then passing one of the segments toward and around the support, and then around the opposite side of the post. The passed segment effectively becomes a tension line under load, restricting outward longitudinal movement, and the opposite segment becomes a take-up line which, when pulled, allows free longitudinal movement to take up slack in the tension line for tightening same.

Abstract: An elongated hydraulically foldable and elevationally adjustable ramp connectable to a draft vehicle and including leading and trailing ramp sections that are pivotally joined and foldable between an inclined loading position and an upright traveling position, and a ground-bearing pad pivotally connected and depending freely from the ramp at a position forward its center of gravity, such that upon activation of a hydraulic cylinder extending between the trailing and leading ramp sections when in loading position, the ground-bearing pad engages the ground and causes the forward end of the leading ramp section to elevate above the bed level of the trailer to facilitate mounting and removal of the ramp therefrom. The hydraulics for the ramp are self-contained on the ramp for independent operation and positional control without connection to an external source.

Abstract: A self-adjusting knife assembly for scoring tenders from chickens, the assembly having a pair of generally parallel handle halves in spaced relation and positively connected by a connector pin, to permit a pair of generally parallel knives, which are mounted on the forward ends of the handle halves, to move toward and away from each other. The connector pin is mounted so that the two handle halves are positively connected to permit relative rocking movement therebetween about a transverse axis disposed in a vertical plane, to thereby permit the pair of knives to self-adjust and follow the opposite sides of the keel bone of the chicken throughout its length, and thereby separate the tenders cleanly from that bone. Spring extends between the forward portions of the two handle halves and constantly gently urges the knives apart. The knives follow the contour of the keel bone, despite its irregularities of shape, as the knives are moved downwardly throughout the length of the keel bone.

Abstract: A window sash tether clasp and anchoring system which is externally mountable for universal use in connection with new or pre-existing conventional double-hung windows, wherein the sash tether clasp is externally mounted on the lower sash of such window and includes an outwardly extending catch having a pair of transversely spaced opposed legs which are designed to engage in the outer diverging walls of a bell shaped anchor that is attached to the end of the balance cord leading from the window balancing system. The externally mountable tether clasp further includes an outwardly extending spring lock which includes an arcuate portion, the extrados surface of which faces the catch and extends within the lower bell mouth of the anchor, thereby holding the anchor in releasable engagement with the catch of the tether clasp.

Abstract: A bullet comprised of a jacket of malleable metal having a closed nose portion and a rear end portion defined by a cylindrical wall, the closed nose portion having wall-weakening areas encapsulating a forward core made of a deformable material which promptly deforms, collapses axially, and expands radially to a substantial extent along with the weakened wall areas, when the bullet strikes a target. The nose portion has wall-weakened areas which are ruptured by the core material to produce a collapsing and radially expanding action. These weakened wall areas are in the form of longitudinally extending, deep, internal or external, circumferentially spaced grooves with underlying web areas which are ruptured by the core material, to produce the collapsing and expanding action. This core is preferably made of rubber, urethane, silicone, or one of a substantial number of plastics, each of which has a hardness within a range of Shore A 20 to Rockwell 122.

Abstract: A mushrooming bullet having a highly improved performance in the retention of the lead core within the bullet jacket subsequent to impact, and in performing effectively over a substantially wider velocity range, the bullet retaining its lead core within its jacket substantially 98-100% of its firings at high velocities, and mushrooming more effectively at lower velocities than conventionally manufactured bullets. The jacket is characterized by a base portion which has a substantially larger interior diameter than its shank portion, and a mouth portion which is substantially softer than its shank portion. The mushrooming of the nose portion of the core and the mouth portion of the jacket is effectively arrested by the harder thick shank portion when the bullet strikes a target, and thereby minimizes the loss of lead from the core.

Abstract: A one-piece toilet seat hinge composed of an elastomeric material throughout, and having the characteristics of rubber, and including a flat flange member and a coplanar support shank, the flange member being designed to be connected to the toilet seat and the support shank being generally cylindrical in shape and externally threaded to facilitate mounting thereof within a cavity normally found on the toilet stool for connection of the seat thereto. The flange member has lower peripheral portions having sufficient memory to cause the toilet seat to swing from a horizontal orientation, upon release, to a vertically extending orientation, thereby obviating the likelihood of the seat being soiled by a subsequent male urinator.

Abstract: An integral fishing vest and tackle carrier having elongated front and rear vest panels, each of which includes an upper section and a lower section adapted to be foldable over the upper section, thereby creating a pocketed storage compartment between the upper and lower sections within which fishing tackle may be carried for convenient access. The lower section of each panel is constructed with a guide that is adapted to receive and hold in place at least one tackle carrier with organizing compartments that are easily accessible to the fisherman when the lower section is released and unfolded from the upper section to which it is normally secured. The vest is readily reversible between front and rear panels such that access to either is readily available. The vest may also be optionally constructed as a life vest, with permanent or removable floatation-wear incorporated therein.

Abstract: A bullet comprised of a jacket of malleable metal having a closed nose portion encapsulating a forward core made of rubber, the nose portion having circumferentially spaced, axially extending deep scores in its nose-defining walls, and a rear core within the jacket made of a malleable metal preferably softer than that of the jacket and hard-seated against the rear of the rubber core to bring pressure against the interior surface of the meplat and the interior surface of the nose-defining walls of the nose portion, whereby upon the bullet striking and penetrating a target, the scores will rupture and the nose-defining walls of the nose portion will collapse axially and open, and together with the rubber core, will expand substantially in a radial direction to thereby provide an adequate penetration, optimum expansion bullet.

Abstract: A lead-free, heavy-metal free rim-fire priming composition consisting essentially of diazodinitrophenol (DDNP) as a primary explosive, a low percentage of a secondary sensitization explosive (tetracene), with a high percentage of abrasive (ground glass) and a very low percentage of an effective lead-free, heavy-metal-free oxidizer. A strong binder is added to aid in the installation and retention of the composition within the rim of the casings. A dye is also included for the sole purpose of facilitating visual inspection within the casing after installation of the composition within the rim. The high percentage by weight of the ground glass (46-60%) in combination with DDNP is of principal importance. The preferred mix is comprised of 29.8% of DDNP, 4.0 tetracene, 57.0% ground glass, and 7.5% potassium nitrate with 1.5% gum tragacanth added as a binder and 0.2% Prussian Blue as a dye.
