Abstract: An apparatus for detecting temperature variations over selected regions of living tissue. The invention relates to the apparatus and to the method of detecting said temperature variations for aid in the early detection of malignant tissue in the breasts. The invention provides for the use of liquid crystals encapsulated between elastic flexible sheets which represent a composite film. The crystals are responsive to changes in temperature of said tissue to display a color pattern on said film representative of said temperature variations. The film conforms to the contour of the tissue to which it is applied, without materially deforming said tissue, by evacuating air from between said film and said tissue. The color pattern produced on said film is observed and is recorded photographically to obtain a thermogram of said temperature variations.

Abstract: A laminated tubular connector for splicing or terminating electric conductors, comprising an outer layer of a heat shrinkable dielectric material, e.g., polyethylene terephthalate, and an inner layer of relatively soft, self-adhesive, low temperature flowable thermoplastic material, preferably a polyvinyl acetate composition. When heat is applied to the connector, the outer layer shrinks and the inner layer functions as a sealant and a cushioning agent. In some applications, the adhesiveness of the inner layer may be used to hold the connector in place during subsequent operations by pinching the connector so that the depressed portions of the tube adhere to each other prior to heating the connector to shrink the outer layer.

Abstract: A high performance magnetic tape transport and tape cartridge. The cartridge includes coplanar hubs carrying tape rolls on fixed axes, a brake system which urges each hub in a direction to tension the tape when the cartridge is removed from the transport, and a pair of doors which completely enclose the front face of the cartridge when the cartridge is out of the transport and automatically open to expose the entire front face of the cartridge when it is inserted in the transport. The transport includes a pair of capstans, each mounted on its own carriage assembly with its own drive motor. The capstans have a high friction surface. The carriage assemblies are spring biased with equal force toward the front of the cartridge. When the cartridge is inserted in the transport, the capstans drivingly engage the peripheries of the tape rolls, and magnetic transducer heads in the transport engage the front face of a span of tape between the rolls.

Abstract: A spill-over type spa is disclosed for use with an existing swimming pool. Water enters the spill-over type spa in the usual manner, but is thereafter permitted to spill-over into the adjacent swimming pool via a transition section integrity formed with the spill-over spa. The transition section rests on an upper peripheral edge of the swimming pool, thereby permitting water within the spa to spill-over into the pool. The spa is placed adjacent an existing pool in a manner to preserve integrity of the existing pool wall, yet permit the spa to function with the pool.

Abstract: A diver's floater is disclosed having a spherical float body with a circumferential groove thereabout in which a line may be stored, which line connects the float body to the diver. A clip, attached to the float body, under which preselected turns of the line may be secured, serves the dual purpose of preventing excessive line from unwrapping and providing distance indications to the diver. In one embodiment of the invention, wherein the float body is hollow, access to the float body interior is provided so that equipment may be stored therein. A support is also provided for storing equipment and the like external to the float body.

Abstract: A boot support device including a pair of shanks which engage each other intermediate their ends but closest to the upper end of the device. The inter-engagement of the shanks effects a rocking movement between the shanks to cause the lower ends of the shanks to move apart to facilitate insertion into the legs of boots. The divergence of the lower ends is effected by causing sections of the shanks near the upper ends to be squeezed together. A predetermined divergence may be effected by movement into a certain position of a hollow slider which is displaceable along the shanks. Divergence of the lower ends of the shanks may also be effected by manually squeezing together opposed sides of a loop-shaped connection extending between the shanks at the upper end.

An electric motor is pivotally mounted on the end of a telescoping rigid tubular handle with the electric cord for the motor extending along the interior of the handle to a switch mounted on the opposite handle end. A plurality of short sections of flexible line are mounted on the motor shaft for rotation with a high velocity by the motor. Each of the sections of line have a preformed configuration having a portion which extends in a generally radially outwardly direction from the shaft and an integrally connected portion which then extends in a generally concavely curved direction toward the direction of shaft rotation. A bracket is mounted on the motor housing and has a pair of rollers which are mounted at right angles with respect to a third roller to provide for rolling engagement with the horizontal and vertical outer edges of a rain gutter.

Abstract: The use of liquid aspirators which are connected to conventional vacuum cleaners is known. In this invention a reservoir-body of an elongated form extends at its lower part to a nozzle, and at its upper part to a lid which is provided with an end-piece for the attachment of an external hose from a conventional vacuum cleaner. The said lid is placed on the inside of a lid-handle which extends above the reservoir-body. A tube following the nozzle penetrates into the interior of the elongated body-reservoir to discharge the liquid, where in the interior of the said body spacers and separators are provided, while a transparent window permits viewing the level of the liquid and a float closes the air vacuum when the level of the liquid reaches a predetermined value. Some baffle-plates and a filter are provided to prevent sprayed drops of water from being drawn towards the vacuum cleaner and damaging its electric motor.

The composite structure is subdivisible across the bay portions into two identical pairs of slider-lock pin members and inserting pin members.

Abstract: The invention is an apparatus for collecting and transporting thermal energy as vaporized fluid. The vapor will flow from a heat absorption chamber and through a conduit to a point of use where it is condensed. The heat absorption chamber includes a sump in its lower portion to hold a puddle of fluid. A heat source directed against the chamber vaporizes the fluid therewithin and a replacement fluid supply connects with the chamber to maintain the level of the puddle during vaporization. The chamber of the preferred embodiment of the invention is an elongated heat absorption pipe mounted horizontally to maintain the puddle at the lower portion of the pipe. The heat absorption pipe is mounted in a solar collector to receive concentrated solar energy as from a reflector system.
