Abstract: A retractor has a blade which is in contact with a surgical wound. A handle has one end supported by the blade and extends substantially normal thereto, and has an opposite free end. A brace plate is attached to the free end of the handle and fits against the user's forearm to stabilize the retractor. A hand grip is attached to the handle between the blade and the brace plate. The arrangement is such that a fulcrum is created at the attachment between the hand grip and the handle, whereby the larger and stronger muscles of the user are available with a mechanical advantage to control the retractor. The blade may assume a variety of configurations and the blade, hand grip and brace plate are pivotable in a variety of planes relative to the plane of the handle.

Abstract: A tray includes adjustably positioned support members for supporting multiple lead integrated circuit components of various sizes and configurations. The components are supported by the support members so that the component leads do not make contact with said support members. A cover is disposed on the tray to protect the components when storing and/or transporting same. The cover is arranged to receive another tray whereby a stackable arrangement of covered trays is provided. The stackable arrangement may be strapped for providing a storable/transportable package of microelectronic components.

Abstract: A sliding panel includes top, bottom and side members. A corner roller arrangement has integral corner keys, whereby a corner member abuts the ends of the panel members at each of the corners thereof. Each of the corner members includes a spring biased roller whereby the rollers are self-leveling at each of said corners. A clip is arranged to adjust the roller to a plurality of inwardly and outwardly extensions relative to the top and bottom panel members. The arrangement is such that the corner members are effective as an installation guide for the sliding panel and impart an anti-rattle feature thereto.

Abstract: A center member is disposed between a pair of end members. A cylindrical member is accepted in a hole in one of said end members and an other cylindrical member is accepted in a cavity formed by the cooperative arrangement of the other of the end members and the center member whereby the one and the other cylindrical members which are in parallel planes are coupled. The arrangement is such that cylindrical members of varying diameters and having their axes angularly displaced relative to each other within their parallel planes are accommodated.

Abstract: A pair of pivotally attached handles are normally displaced away from each other via a spring biasing arrangement, and are displaced toward each other as by squeezing the handles against the spring bias. A wire or pin is introduced into a fixed fracture or osteotomy and an end thereof is received in an angled slot at an operating portion of one of the handles so that when the handles are squeezed against the spring bias the operating portions of both of the handles cooperate to bend the wire or pin to prevent migration or skin puncture, as the case may be.

Abstract: A frame supports stereoscopically paired pictures and a pair of lenses for viewing the pictures. The frame is foldable to vary the distance between the lenses and the pictures so that an observer can focus on the pictures in accordance with the observer's particular optical characteristics, whereby a three-dimensional picture image is viewed. The distance between the viewing lenses can be varied to accommodate variations in the distance between the eyes of different observers. The entire viewer can be folded flat for storage and shipping convenience.

Abstract: A base is mounted to a frame and a pair of foldable basket sides are mounted to the base and to a rim above the base. A pair of basket ends are displaceably mounted the rim. The sides are folded and the ends are displaced to an upright position to cooperate with the base and the rim for forming a rigid basket. The sides are folded and the ends are displaced so that the rim is adjacent the frame, whereby the rim receives a flat surface so as to render the apparatus in a table top configuration. Legs are provided for clamping the apparatus to supporting bars on a wheelchair or like equipment, whereby the independence, productivity and comfort of a user in a variety of environments is maximized.

Abstract: An oxygen tank holder of a suitable fabric material includes a pouch for holding an oxygen tank, and which pouch is strapped at its upper and lower ends to the back of a wheelchair. The straps are adjustable to accommodate various size wheelchairs and so that the pouch can be displaced away from the center of the wheelchair to avoid interfering with the back of the user of the chair, as is desireable.

Abstract: A sliding panel includes a frame having top, bottom and side members. Expanders rotatably supporting rollers are partially disposed within the top and bottom members and are displaceable against spring tension inwardly and outwardly of said members. Clips are provided for retaining the expanders partially disposed within the top and bottom members and for limiting the outward displacement of the expanders. The arrangement described provides self-leveling of the rollers along the entire width of the panel.

Abstract: A muzzle is arranged to fit over the snout of a dog and includes a pair of straps which are adjustably crossed around the neck area of the dog to secure the muzzle in place. A loop member extends downwardly from the muzzle and includes a ring to which a leash or the like for guiding the head of the dog is attached. An arrangement is thus provided which is useful for a variety of activities involving guiding a dog.

Abstract: A holder for an infant nurser bottle includes an elongated strap-like member which is formed at one end so as to be looped around a securing member and formed at the other end so as to cooperate with a lower bottle girdling strap secured thereto to provide a harness for nesting the bottom and lower circumference of the bottle. An upper girdling strap is secured to the elongated strap-like member for girdling the upper circumference of the bottle.

Abstract: A bracket is mounted to an archery bow so as to be adjustable relative to the bow string to compensate for arrow overdraw. A body member is adjustably mounted to the bracket to provide accurate arrow flight and to avoid interference of arrows of various diameters with the bow. The body supports three rollers. The rollers cooperate to support a nocked arrow in a readied position and to guide the arrow upon release. The roller arrangement enables arrows of various diameters to be retained and guided and provides for easy insertion and retention of the arrow in the device.

Abstract: A level includes a plurality of telescoping members locked in a telescoped position, whereby the effective length of the level is adjustable so that the level is useful in establishing horizontal for a structure of an extended length and for establishing a plumb line.

Abstract: An arrangement including a suction pump, a pipette, an application tip and a plurality of ligating rings which are carried on the application tip. The application tip is disposed in cooperative relation with the pipette so that the ligating rings may be transferred from the adapter tip to the pipette while being gradually stretched. The pipette is disposed in an incision exposing the ovarian sack of a small mammalian creature, whereupon a suction or vacuum is generated by the pump to capture the ovarian sack, after which a ligating ring is slipped off of the pipette and contracts to ligate said captured sack. This enables resorption of the ligated ovarian sack into the creature and stabilization of hormonal activity as is desired for experimental purposes.

Abstract: A raised superimposed toilet seat is adapted to fit on a conventional toilet seat and is contoured to particularly meet the needs of patients who have undergone unilateral or bilateral total hip replacement procedures. The seat is contoured so that when the patient is seated thereon, the patient's legs are kept adducted in the proper position, ensuring that the patient's hips are placed with the proper amount of hip flexion and abduction to prevent hip dislocation.
