Abstract: Dental articulator apparatus includes a base articulator plate and a top articulator plate mounted on a support stanchion. On confronting surfaces of the top and base articulator plates are formed confronting mold cavities that receive dental “stone” mixed to a “workable” consistency so that the cavities can be filled with plastic “stone” to reconstruct from a “negative” impression a “positive” replica of a patient's teeth in stone. A press ejects the dental stone casting from the mold cavity in which it is formed. Embedded in the stone casting is a plastic sleeve. The plastic sleeve slidably accommodates a guide pin that passes through the cavity wall. To remove the dental stone casting from the mold cavity, the guide pin is first removed by sliding it out of the plastic sleeve. The ejected dental casting may be segmented to separate one stone “tooth” from another.

Abstract: Presented is a humane wild animal trap device that includes a trigger mechanism having four easily assemblable elements for supporting the bait, a bottom flat sheet on which the trigger mechanism is supported when set and baited, and an enclosure the open side of which is superimposed on the flat bottom sheet and which enclosure is tilted upwardly from one end so that the elevated end rests on a selected one of the four elements included in the trigger mechanism and which element is released from a second element that supports the bait when a wild animal takes the bait, thus causing the elevated enclosure to fall onto the flat bottom sheet to trap the wild animal within the enclosure.

Abstract: Presented are electronically controlled optical shutter spectacles for achieving biofeedback between the operation of the optical shutter spectacles when worn and the physiological rate and timing of human visual processing of the wearer of the spectacles to provide further enhanced perception of fast-moving objects or surroundings and to train and condition the human physiology to retain enhanced motion perception capability for an indeterminate time following removal of the spectacles.

Abstract: Presented is an end-effector for grasping integrated circuit wafers with a talon-like device that effectively grips an arcuate peripheral “free zone” of the wafer-without effecting contact of the wafer in a manner to contaminate it.

Abstract: Presented is a quick-engaging and quick-release device for securely supporting elongated objects in either a horizontal or vertical attitude on a vertical support structure or surface or overhead on an appropriate support surface. A base member has end and side walls. Two oppose side walls are correspondingly notched. A resiliently deformable block of cushioning material may be removably inserted into the hollow shell so that it is flush with the top edges of the end and side walls. A hollow cap member is pivotally attached to the base member and may be pivoted away from the base member into open position to receive an elongated object. When the hollow cap member is pivoted into closed condition, the elongated object is retained by and between the base member and the cap member. A latch assembly is provided for selectively releasably locking the cap and base members in closed condition about the elongated object.

Abstract: Presented is a simplified modular free-standing workbench including a pair of laterally spaced and parallel workbench-top support members to which a workbench top is rigidly yet detachably secured by quick-connect/disconnect fastener elements. Pairs of tubular steel legs rigidly yet detachably engage the associated ends of the tubular bench top support members. Foot members are rigidly yet detachably engaged with the bottom ends of the leg members to enable height adjustment. Transversely extending tubular members rigidly yet detachably engage the confronting surfaces of the laterally spaced top support members by quick-connect/disconnect fastener elements to maintain their parallelism. An auxiliary shelf may be rigidly yet detachably mounted on the workbench by an auxiliary shelf support framework supermimposed over the workbench and secured thereto by quick-connect/disconnect fastener elements.

Abstract: A lower leg protection means for preventing injury to a person's lower leg. The lower leg protection means includes a pair of thin, laterally curved rigid members which are enclosed with foam material such as polyfoam and which are essentially made of carbon fiber graphite. Each of the thin, laterally curved rigid members is fastened about a particular region of a person's lower leg with fasteners which includes a three first strips of hook and loop fasteners, a pair of elongate elastic members, and a pair of second strips of hook and loop fasteners attached to the elongate elastic members. One of the thin, laterally curved, padded rigid members is adapted to fit about and protect a person's shin, and the other of the thin, laterally curved, padded rigid members is adapted to fit about and protect a person's Achilles tendon.

Abstract: Presented is a new product, namely a poultry wing including a plurality of segments, either raw or cooked, and the method and means by which the new product is produced by extending the plurality of segments into longitudinal orientation and thereafter engaging all segments with means for retaining all segments in extended or longitudinal orientation or alignment for processing, packaging, cooking, and consumption. Because of the interconnection of these normally pivotally associated segments of the poultry wing by muscle tissue, when a poultry wing is cooked while these segments are free to pivot in relation to each other, the muscle tissue that interconnects these segments contracts and consequently the segments of the wing are pulled together into substantial parallelism to form a tight interconnected mass that is difficult to cook uniformly, and which is inconvenient to consume because of the need to physically separate the contracted mass.

Abstract: Presented is a scouring apparatus for holding a scouring pad in position for use. The apparatus includes a scouring pad holder formed as a shell symmetrical about a central axis and having a tubular “grasp” portion for engagement by either the fingers or a handle assembly, and further having a skirt portion defining a shallow recess within which is mounted a tine having at least one spiral turn the free end of which lies outside the recess so that the tine may be rotated into an associated scouring pad to draw the scouring pad into the shallow recess and detachably retain the scouring pad therein during use, but enabling removal and laundering or replacement of the scouring pad.

Abstract: Presented is a multipurpose tool formed from an elongated unitary length of material narrow in comparison to its length and having a main body portion on one end of which is integrally formed a reentrant portion that functions as a clip to retain the tool clipped within a pocket, and which also provides a lip portion diverging from the main body portion and against which the thumb may rest during use. The end of the main body portion remote from the reentrant portion is provided with one or more sharpened edges, and in one embodiment two opposed recesses are formed in the lateral edges of the main body portion adjacent its sharpened end edge. A portion of the lateral edges that define the recesses are also sharpened as a continuation of the sharpened end edge.

Abstract: An apparatus and method of rehabilitating the stagnant bottom of water wells using existing well equipment including a pump and a pressure tank, augmented by valves and a conduit that extends from the surface to near the bottom of the stagnant region at the well bottom. Water pumped from the well is returned under pressure to the well bottom where it displaces the fouled contents of the stagnant region at the well bottom. This elevates the contents of the well bottom to a position above the pump intake, where the contents can then be pumped to waste.
