Abstract: An oxygen sensor or cell for measuring the oxygen content of a specimen includes a body with a chamber that houses an electrochemically active anode and an electrochemically active cathode. A chemically inert, electrically inactive porous material is disposed between and in contact with the anode and cathode. An anode connector is in contact with the anode and a cathode connector is in contact with the cathode. An electrolytic solution of potassium hydroxide and a dissolved metal saturates the porous material and makes electrical connection between the anode and cathode. A specimen to be measured is introduced into the chamber. The electrolyte promotes catalytic reduction of free oxygen molecules carried by the specimen. The magnitude of current flow through a resistive load connected between the anode and cathode connectors is directly proportional to the quantity of oxygen present in the specimen.

Abstract: A hydraulic resistive apparatus that is used in exercise equipment includes a resistive device and a heat dissipating device. The resistive device includes a cylinder and a piston that are movable relative to one another. A working fluid is contained within the cylinder. The heat dissipating device is securely engaged to the outside of the cylinder and includes a tubular body having a plurality of cooling fins extending from its external surface. As heat is generated by the relative movement of the cylinder and piston, it is conducted to the heat dissipating device and then radiated into the surrounding environment. The body of the heat dissipating device includes a longitudinal slit that permits temporary opening of the body so as to permit it to be slid onto the cylinder and, when released, results in full surface-to-surface contact between the heat dissipating device and cylinder.

Abstract: A device for securing and restraining a pair of adjacently mounted bicycles includes a body having first and second portions with at least one strap slidably connected thereto. The first portion is configured to engage the foot pedal of one bicycle while the second portion is configured to engage the frame of a second bicycle. At least one strap is provided for securing the device to at least one of the bicycles.

Abstract: A non-toxic moldable phosphorescent marker has phosphorescent pigment particles that are suspended in a milled mixture of an inert filler and a wax blend base. The phosphorescent pigment particles, which impart luminescent properties to the marker, are excited by light. The composition of the marker is such that it leaves a strip of phosphorescent marking material on a surface against which the marker is rubbed. The deposited material contains the suspended phosphorescent particles, which luminesces when excited by light.

Abstract: A method and device involving use of the reaction product of an aldehyde acidified with sulfuric acid in acetone for sensing moisture. The reaction product is used as a coating for colorimetric detection of humidity, the color of the coating changing as a function of the humidity level. The coating is applied to a thin layer chromatography plate which is received in a badge housing to provide a real-time colorimetric dosimeter for monitoring humidity and indicating its presence.

Abstract: A one piece cushioning device for a child's car seat has a main body defining a head rest and a pair of extending arms that define a pair of shoulder belt covers. Each arm is sized and shaped to fit around a shoulder belt of the car seat, closures being provided to secure the arms around the shoulder belts. The main body is positioned between a child's head and the back of the car seat and serves as a cushion to protect against irritation to the child's head and the arms protect against irritation to the child's neck.

Abstract: An adjustable weight-lifting bench is disclosed adapted such that it can be converted from a flat to a sitting position with little or no displacement of the user's head and shoulders in relation to the stationary upright barbell supports. The bench seat frame is pivotally connected to the back frame, a second end of the seat frame is pivotally connected to one end of a support arm, and the second end of the support arm is pivotally connected to a base frame, together with means for releasably connecting the support arm to the back frame at different locations along the length of the support arm.

Abstract: A folding carrier that is mountable upon a generally planar member includes a rotatably connected frame and carrying member. The frame is a substantially U-shaped member having a pair of legs and a back, each leg having a stop. The carrying member, which is also a U-shaped member, is constrained for limited rotational movement relative to the frame between a carrying position and a stored position. In its stored position, the carrying member is in a side-by-side relationship with the frame and inclined backwardly toward it. When in its extended position, the carrying member is substantially perpendicular to the planar member upon which the carrier is mounted. The carrying member bears against the stops of the frame to prevent further rotation beyond the preferred carrying position. Frictional elements that are mounted on the frame and carrying member engage the generally planar member and prevent unwanted movement of the carrier.

Abstract: The method and associated apparatus for recovering fractions from hydrocarbon material, comprising the steps of generating electromagnetic energy generally in the frequency range of from about 300 megahertz to about 300 gigahertz, in accordance with the lossiness of the material, transmitting the generated electromagnetic energy to the hydrocarbon material, sensing the temperature of the hydrocarbon material, varying the electromagnetic energy in accordance with the sensed temperature, exposing the hydrocarbon material to the electromagnetic energy for a sufficient period of time to sequentially separate the hydrocarbon material into fractions, and removing the resulting fractions.

Abstract: An improved support belt for radiation shield garments has a padded, slip-resistant rear support element, one or more elasticized elements, one or more connecting elements, and adjustable fastening means for securing the ends of the belt to one another. The padded, slip-resistant rear support element comprises a relatively thin, flexible foam core that is covered with a foam-backed vinyl, the foam facing outwardly for frictionally engaging and supporting the radiation shield garment at the waist of a user.

Abstract: A safety net assembly for covering and uncovering a substantially rectangular open pit includes a safety net with a rope edging and a guide cable that is mounted about the perimeter of the pit, the guide cable defining a pair of track along which the safety net is slidably moved to its opened and closed positions. A plurality of closable links are attached to two sides and one end of the safety net and slidably mounted to the guide cable at two sides and one end of the pit. A plurality of snap rings are attached to the other end of the safety net and releasably attached to the guide cable at the other end of the pit. The links permit the safety net to be drawn open and closed, and the snap rings secure the safety net over the pit.

Abstract: A method and apparatus for providing circulation to distal organs and blood flow for intercostal lumbar perfusion during aortic surgery by means of an intercostal and lumbar perfusion shunt having a main tubular member defining a first flow path and a plurality of side tubular members connected intermediate the ends of the main tubular member and defining a plurality of second flow paths. The method includes the steps of shunting a pathologic section by connecting the free ends of the main tubular member to the aorta proximal and distal to the pathology for providing blood flow to the distal organs and by connecting the free ends of the side tubular members to the intercostals through an opening in the aorta for providing blood flow to the intercostals during surgery.
