Abstract: An apparatus for handling a patient's blood during a medical procedure which is convertible for use after the procedure for at least one further use. The apparatus comprises a reservoir having a port comprising at least one opening. A primary device, alignable with the port for adapting the reservoir for use during the procedure. The apparatus further comprises one or more secondary devices each alignable with the port means for adapting the reservoir for one or more further uses after the procedure. The primary device and the secondary devices are slidably mounted on the apparatus between tracks, with the primary device initially aligned with the port to allow the reservoir to be used during the medical procedure. The tracks allow the primary device to be moved out of alignment with the port and allow at least one of the secondary devices to be moved into alignment with the port so that the reservoir can be used after the medical procedure.

Abstract: A color variation device for educational and/or entertainment purposes has a color mixing unit which comprises a number of color variation components.. The color mixing unit can be set in motion by a motion manipulation unit while each color variation component contains a mechanism that can make the color on the visible surface of the color variation components be changible by the players. The color variation components are suggested to be configured with triangular pyramidal shape that are radially placed around the horizontal center of a circular color mixing unit sequentially in the direction of the color mixing unit motion. Different combination of colors selected on each color variation component on the color mixing unit can generate different colors when the color mixing unit is set in motion by the motion manipulation unit.

Abstract: A toy helicopter device is disclosed which is capable of a projected nose up ascent and a helicopter nose down descent. The device has a streamlined two dimensional main body comprising a nose, stem, and tail portion. The tail portion is hingedly connected to two helicopter blades arranged adjacent and partially overlapping each other. Resilient means located in the gap between the tail and helicopter blades can be adjusted to control helicopter blade deployment early or late during the catapult projection. At a selected rotational velocity from the catapult, the spinning toy helicopter deploys the helicopter blades to approximately right angles to the main body and the device continues to rotate slowly to the ground. The launch angle relative to the ground is not significant in determining a successful deployment.

Abstract: A construction kit for toy building structures includes a plurality of planar logs with opposed notches at the lateral ends thereof. The logs may be interconnected in a normal position by notch engagement or one atop the other by intermediate mounting plates. Roof logs and/or mounting plates utilize angularly positioned notches to mount logs in an angular relationship relative one to the other. Slider elements mount movable logs in a slidable relationship to a fixed log.

Abstract: A toy waterwheel including a transparent water-tight container, a rotatable wheel connected to the interior of the container, an electric pump for pumping water to and from the container, a nozzle connected to the container for directing water to the wheel to turn the wheel, a first hose connected to the electric pump and the nozzle for conveying water to the nozzle, and a second hose connected to the container and to the pump for conveying water from the container to the pump.

Abstract: A doll (10) that dances by reciprocating a hip portion (20) and that simultaneously moves along a surface (S) in a generally curving path. The doll has a base (40) with a drive wheel assembly (70) and a crank (55) that reciprocates the hip portion (20). Preferably, the doll (10) also has sound emitting means (110).

Abstract: A bubble bath bubble toy. This toy with a rotatable hub for altering bubble size is designed to produce bubbles in clear, soapy or bubble bath water. For years children have been fascinated by the production of bubbles. This apparatus allows children to safely and easily produce bubbles on their own. With this apparatus, the user turns a crank which activates several gears turning a bubble wheel with aeration vanes. The motivation of these aeration vanes produces a mixing of air, water and bubble mixture sufficient to produce bubbles. This toy allows for the production of bubbles from previously utilized water containing some amounts of bubble fluid. This helps to limit the cost of bubble production.

Abstract: A multi-disc flying device is disclosed in which outer and middle discs rotate in opposite directions by a force generated by the unwinding of a torsion spring. Downwardly extending deflecting plates on each disc generate an upward force during rotation to prolong the flight of the device. An inner disc rotatably attached to the middle disc has a normally curved rudder assembly to impart a curved flight path to the device so that it will return to its launching point. A propeller is driven by relative movement between the rudder and the inner disc to provide a propulsive force to the flying device.

Abstract: A method for percutaneously fixing and fusing the lumbosacral joint and a guide device for accurate placement of instrumentation to effect the fixation or fusion. The inventive method comprises placement of pins along bony canals leading bilateral of the spine from the pelvis to the S1 pedicles and then the vertebral body of L5.

Abstract: A whole arm orthosis with plural degrees of freedom dampens limb tremors. A linkage mechanism permits movement of the forearm in a horizontal plane, as well as tilting of the forearm out of the horizontal plane. A sensor coupled to the joints of the linkage mechanism detects the angular velocity of rotation. A brake applies resistive torque to the joints in accordance with the angular velocity of rotation.

Abstract: A head immobilization device is disclosed comprising a foundation portion and a restraining portion. The foundation portion comprises a foundational panel and an adhesive first spine board engaging element situated on the lower surface of the foundation panel. The restraining portion comprises a base panel, two side panels extending laterally from the outer sides of the base panel, and at least one band of material for affixing the side panels to each other in suitable conformance with the patient's head.
