Liquid sensors are contained within the vessel for detecting the presence of urine and automatically activating a pump to draw the urine through a tubing to a temporary storage chamber. A liquid impermeable liner is place within the collecting vessel for improved hygiene and for directing the urine away from the individual.

Abstract: A tube clamp for dependably occluding the flow of fluid through a deformable tube includes a pair of pin members mounted on a supporting surface adjacent to a pivotal body that includes an edge portion adapted to be pivoted into the space between the pin members to pinch the tube against the pin members, thereby occluding the flow of fluid through the tube.

Abstract: An article of luggage includes a garment bag portion and a valet case which is selectively removable from the garment bag portion or can be stored within the interior of the garment bag portion. The valet case is deployable to a supported position adjacent to the garment bag portion for convenient use. The garment bag portion, while having a flexible outer main panel, is selectively reinforced along a peripheral wall and is provided with roller support wheel members so that the bag will retain a substantially vertical orientation over the roller support members to allow the article to be rolled across a supporting surface while in a self-supporting folded condition.

Abstract: A system for public display of ultraviolet radiation levels wherein said radiation is collected and measured by one or several optical collectors or sensor assemblies at remote sensing stations. Optical fibers receive and then convey the radiation of the sun through a filter and onto a photovoltaic sensor, measuring the intensity of the ultraviolet radiation. An electrical signal proportional to the ultraviolet radiation is produced with the signal being amplified and either used directly as analog data or converted to a digital signal for the modulation of a radio transceiver. The signal is transmitted to a transceiver of a central data processing station, where it is processed. The processed signal is retransmitted to a receiver in which the processed signal carrier is demodulated and the signal fed to a display station providing the level of exposure to the public.

Abstract: A blood filter device for separating gas bubbles from a flow of blood includes a filter medium in a lower body portion of the device through which the blood must flow before being directed through an outlet tube. An upper cap sealed to the top of the lower body portion includes a blood inlet tube into which a conical dispersion plate is projected so as to decrease the rate of flow of the blood. The rate of flow further decreases as it enters a debubbling chamber in the cap. A top wall of the cap defines a sloped and arched channel around the inlet tube adapted to direct released gas toward a vent tube at the uppermost extent of the sloped top wall.

Abstract: An apparatus for closely simulating cross country skiing includes a platform on which right and left foot engaging supports are disposed for reciprocatory sliding movement with right and left hand engaging members being operatively connected to the foot engaging supports to reciprocate in a pattern simulating cross country skiing. A control system is employed for controlling the relative movement of the foot engaging supports and hand engaging members so that a slight amount of play exists between the foot engaging supports permitting a smooth gliding motion. Means are also provided in the control system for allowing the hand engaging members to move twice as fast as the foot engaging supports so that the relative movement between the hand engaging members and foot engaging supports more closely resembles actual cross country skiing.

Abstract: A vehicle wash apparatus is disclosed as including a curtain of flexible scrubbing strips which are suspended from an orbiting support member adapted to selectively have the strips wrapped there around to elevate the strips from the path of movement of a vehicle through the apparatus.

Abstract: A time delay corrector corrects the relative time delay or phase error between two signals, for example, stereo audio signals. A window of no correction is established between two threshold levels. So long as a signal representative of the relative phase error on a relatively fast integration basis does not logically exceed the thresholds which define this window, no rapid phase error or time delay correction is accomplished. The window of zero correction thereby prevents any time delay or phase error corrections which might otherwise result from the normal phase fluctuations inherent in the two correlated stereo signals, thereby preserving the stereo imaging and information content of those signals. Upon the occurrence of the need for a relatively major time delay error correction, such as that which originates with tape splices and the like, detection signals logically exceed the thresholds of the window and a phase correction is rapidly attained.

Abstract: A precision pump for moving small volumes of fluid includes an electromagnet in which is reciprocally mounted an armature carrying a diaphragm on one end such that upon reciprocal movement of the armature an alternating high and low pressure can be created in a pumping chamber to move fluid through the pump. In one embodiment of the pump, the electromagnet drives the armature in one direction and a spring returns the armature to effect the reciprocating movement while in a second embodiment a pair of electromagnets are axially aligned and cooperate with a pair of magnets on the armature to alternately move the armature in a linear reciprocating motion as current is alternately applied to the electromagnets.

Abstract: An inhibitor of platelet-related procoagulant activity is included in a collection medium into which a whole blood sample is collected. The inhibitor prevents an initial drop in the recalcified activated clotting time measured during an assay test conducted on the whole blood sample collected in citrate in the medium. The discovery of the problem of the initial drop in the activated clotting time and the solution of including the inhibitor of the procoagulant activity is of considerable importance in heparin therapy, since the initial drop in the activated clotting time of heparinized blood is substantial. The inhibitor can be included with a calcium chelating agent in the collection medium. Prostacylin and imidazole, which is an inhibitor of platelet thromboxane A2 synthesis, are effective inhibitors of this platelet-related procoagulant activity.
