Abstract: A vascular system guidewire composed of a helically wound proximal spring segment attached to an additional helically wound distal spring segment of a more radiopaque material by winding the two segments together over a core. The helically wound springs may be tapered from the proximal to distal segment or straight, and a length of tubing is attached to the proximal end of the proximal spring segment with a ground distal tube segment to make for a flush fitting and a smooth continuous outside diameter of the guide wire. A core wire is attached to the end of the distal spring segment and moveable within the tube and proximal spring providing torque to the entire spring and movement of the core wire allows for varying the stiffness and support of the spring segment and for straightening the distal spring segment.

Abstract: A device and method for detecting bacteria in food substances and the like utilizing a three layer composite consisting of a transparent base, an indicator exhibiting color change when exposed to changes in pH, and a gas permeable cover placeable in proximity to the substance. The method utilizes the generation of CO2 gas as a byproduct of bacterial growth which produces carbonic acid lowering the pH of the substance in the region of the composite resulting in an observable color change as in indication of the presence of bacteria.

Abstract: A novelty light for baseball style sports attachable to the brim of the cap and positioned to illuminate the front of the crown or head covering portion of the cap. A sports team insignia is preferably attached or attachable to the crown in the area of illumination. The light is arranged to flicker or flash on and off at a high rate and may be contained in a housing appropriate to the sport associated with the team insignia.

Abstract: An on-board electrical powered regeneration system for vehicles propelled by an electric traction motor and having an electrical storage cell bank composed of a rotatable flywheel operatively connected to an impeller, a fuel combustor arranged to emit a stream of gas directed to impinge on the impeller, a supply of fuel for the combustor, a generator driven by the flywheel, and electric power control means connected between the generator and the cell bank to convert the electrical output of the generator to a form compatible with the cell bank. Use of the flywheel as a power retainer and booster is also disclosed.

Abstract: Two or more portfolios are slideably attached in face to face relationship to provide in one mode of use a brief case and in a second mode of use a hanging file. In the brief case form, the portfolios are at the same level, the bottom of each being substantially in alignment with the other which is accomplished by for example the use of handles, one on each of the two outer portfolios. In the hanging file form, the portfolios are at different levels, which is accomplished by securing one of the portfolios from a selected point, such as the back seat of a car.

Abstract: A holder for positioning and immobilizing a leg for surgical procedures on an operating table having a pair of opposed curved leg holding members each mounted on a base slidably and rotatably mounted on a rod adapted to be horizontally mounted in relation to the table. Each base and leg holder is secured in a desired position by a clamp mechanism and the device includes a length of flexible cushioned tubing which fits over and between the leg holding members to provide a unified leg support surface.

Abstract: A sport glove finger construction utilizing an asymmetrical pattern resulting in a seam which lies above the tip and on the back of the fingernail of the user.

Abstract: An improved laparoscopic surgical instrument having a proximal control end and a distal surgical instrument end adapted for performing medical procedures through the abdominal wall wherein the surgical instrument is arranged to articulate in a selected plane a full 180 degrees. Actuation of the articulating mechanism is provided by a pair of cables attached to a rotatable cable control whereby rotation of the rotatable cable control draws one cable toward the control handle while simultaneously releasing the other. The distal end of each cable is attached to an opposite side of the surgical instrument which is free to rotate about a pivot in the articulation plane when pulled upon by one of the cables. The cables pass on opposite sides of the pivot allowing for 90 degree rotations each side of the central axis of the instrument.

Abstract: An improvement in the construction of a sports glove having a thumb cross seam located on the back of the thumbnail covering portion and having a lateral seam located on the back of the thumb joining two thumb covering wing sections, the improvement comprising a panel of material inserted on the inner surface of the thumb bridging and attached to the wing sections to replace the lateral seam.

Abstract: A ski storage assembly mountable on a planar surface such as a wall, door, or ceiling consisting of a longitudinal bottom support having a lip for containing the heel of the ski and an upper rotatable bar for retaining the tip of the ski. An optional force bar, mountable midway between the bottom support and rotatable bar and an optional retaining wire are also disclosed.

Abstract: An improved method for the inertial balancing of a plurality of key assemblies having keysticks within a musical instrument keyboard wherein an individual front weight is predetermined for each stick, the method consisting of calibrating each of the keysticks to an identical selected front weight prior to installing the key leads to a preset pattern which result in the final individual front weight for each key assembly.

Abstract: A gravity actuated electrical switch in which electrical contact is made and then broken as the switch is moved from a horizontal to a vertical position consisting of a container within which is disposed a metallic rollable member, a vertical wall member within the container of a height to allow the rollable member to pass over the top of the wall, a pair of electrical contacts capable of being bridged by the rollable member positioned against the wall, and a horizontal ramp member forward of the contacts. Motion of the switch causes the rollable member to move forward, bridge the contacts and then fall to the forward end of the container. Return motion causes the rollable member to move back along the ramp and pitch over the wall without again joining the contacts.

Abstract: A sport glove thumb portion wherein the joining inseam is asymmetrical and located above the tip and on the back of the thumb. A pattern and seam arrangement are also disclosed.

Abstract: Peritoneal dialysis catheter cuffs positioned at one or both ends of the body implantation tunnel to secure the catheter in position and to seal the entrance site against infection are rendered radiopaque by a variety of means to identify the position of the cuffs during and after the catheter implantation procedure. The cuffs may alternatively be adhered to the catheter by an adhesive having a radiopaque material included as an integral constituent thereof, may be mounted coaxially with a band of radiopaque material or may be formed of a fabric having radiopaque material as an integral part thereof.

Abstract: A rotary distribution and air cooling valve for combustion and exhaust gases for an internal combustion engine consisting of a tube mounted in a bore within the engine head having a pair of opposed side ports and an internal barrier which acts as an air fan to both cool the valve site and channel the gases in and out of the engine in timed sequence. A plurality of grooves are disposed on the surface of the tube to provide a labyrinth fluid seal.

Abstract: The method of manufacturing a polyurethane balloon catheter from a length of tubing of such material wherein the tubing is placed in a mold of the desired final expanded shape, the mold and tubing are immersed in a bath of warm water, and air pressure is introduced into the tubing to effect the expansion and then withdrawn to allow the removal of the balloon.
