Abstract: A monitor for remote reading of liquid volumes in pressurized tanks utilizes a hollow buoyant displacement probe extending downwardly from a load cell carried adjacent a top port in the tank. The buoyant probe is optionally formed in detachable segments so that it can be assembled on site at the time of installation. The load cell is suspended from a flange cover acting as a closure for the tank port so that the load cell is freely pivotable on perpendicular horizontal axes, insuring that it is always oriented horizontally. A temperature-reading string is positioned in the open hollow center of the probe and has three spaced temperature sensing units along its length.

Abstract: A container for dispensing a cleaning agent into a tank through an initially sealed opening is disclosed in which a retaining hook is mounted in a recess in the container and adapted to attach the container to the tank and in which a cap is mounted over the opening and adapted to pierce the seal in the opening during installation and to automatically regulate the amount of cleaning agent passing into the tank in a controlled and adjustable manner responsive to ambient pressure changes.

Abstract: Apparatus is disclosed in which a digital display is driven by an electronic output generated in response to field changes which occur when a transformer interacts with a magnetic core driven in a linearized path by a curved Bourbon tube in response to applied ambient pressure. The transformer is a simple variable transformer and the core is configured to follow a radial path within the field of the transformer.

Abstract: Apparatus is disclosed in which a pair of back straps, a pair of neck straps and a linking web combine to hold a neck cushion in place for protecting the neck of an athlete such as a water skier or the like.

Abstract: An adapter for enabling use with bags or bottles of an intravenous administration set having a proximal syringe venting connector with an air cannula. The adapter has a hollow body with threads for engaging the connector, and a spike for piercing an I.V. container, the spike having spaced fluid paths one of which is adapted to receive the connector air cannula.

Abstract: A flow status monitoring method is disclosed for a gravity flow metering system employing a metering chamber separated by a movable diaphragm into two compartments, each with a valved inlet and valved outlet. The system alternately opens pairs of valves on opposite sides of the diaphragm at preselected time intervals to deliver a fixed increment of fluid. Each preselected interval is divided into a series of discrete sub-intervals, and flow monitoring information is generated by displaying a a discrete indicator representative of the sub-interval in which movement of the diaphragm across the chamber is completed.

Abstract: A volumetric infusion actuator providing a slot means for receiving a valved cassette having exposed valve pads. An actuation means for automatically moving individual arms into and out of engagement with the valve pads according to a predetermined cycle which governs flow through the cassette.

Abstract: A method and apparatus for detecting leaking valves in a volumetric fluid delivery system. The system employs a volumetric chamber divided into two compartments by a moveable membrane, with each compartment having a valved inlet and a valved outlet. In the system, fluid is delivered in discrete increments by alternately opening an inlet and an outlet on opposite sides of the membrane. Between such delivery periods, all valves are closed, and then only a single valve is opened. The membrane is monitored to detect movement while the single valve is opened, indicating a closure failure in one of the supposedly closed valves.

Abstract: An improved condensate evaporator is disclosed in which a condensate collecting container supports a salt impregnated pad, a pair of electrodes and a cover assembly. The salt pad is adapted to convert the liquid condensate into an electrolyte on contact, the electrodes are adapted to transmit electrical current through the electrolyte until it evaporates and the cover assembly controls ingress and egress of the liquid and vaporized condensate, respectively, while simultaneously shielding users from electrical hazards.

Abstract: A reflective device for use in a highly moisturized atmosphere is disclosed which comprises a moveable mirror, a housing for holding the mirror and a motor for moving the mirror with sufficient velocity to prevent accumulation of moisture droplets on the surface of the mirror.

Abstract: A display unit is disclosed in which a frame assembly magnetically supports a plurality of removable display strips in predetermined patterns and in which alpha-numeric character elements are magnetically supported on the display strips and frame assembly in information displaying sets referenced in part by markings located on the surface of the display strips.

Abstract: A six sided shelter unit is disclosed in which a fabric covering is disposed around a support assembly and held in place by a top assembly. The support assembly comprises ribs and support legs which cooperate to shape the fabric into a suitable shelter and the top assembly includes a hinge assembly which allows the shelter to be opened by way of two pivoting gate legs. The two gate legs are constructed to swing back over other support ribs and legs so as to provide an especially wide opening.

Abstract: An emergency light unit is disclosed in which a relay controlled low voltage bulb is initially responsive to line voltage and alternately responsive to battery voltage. A test switch is included to permit instant determination of line voltage and battery status.

Abstract: An assembly is disclosed which comprises brackets and a template for facilitating the mounting of a replacement article such as a compressor or the like on an existing base. The brackets are adapted for adjustable mounting on the base and the template has arms joined in adjustable relationship by a central pivot clamp so that the brackets and template can cooperate to establish an index which will align mounting elements in the base in coincident relationship with corresponding mounting elements on the replacement article.

Abstract: Apparatus for automatically scrubbing a user's hand and fingers is disclosed in which three brush assemblies cooperate to perform the cleaning function. The first brush assembly includes a rotatable knob having outwardly projecting exterior bristles, the second includes a rotatable hollow cylinder annularly surrounding the knob and including inwardly projecting interior bristles, and the third bush assembly includes three individual rotatable finger brushes disposed between the knob and the cylinder in which each brush is hollow, has inwardly directed interior bristles and outwardly directed exterior bristles.

Abstract: A unitary tailpiece is disclosed which supports a bridge assembly and which has top accessed sockets and slots adapted to anchor and hold the strings in proper position on a stringed instrument.

Abstract: A method for regulating temperature and other characteristics of a gas stream flowing in a system is disclosed wherein a liquid is divided into droplets, the droplets are introduced directly into the gas stream to establish a heat exchange interface and the temperature of the liquid is regulated in order to maintain the temperature of the gas stream at a predetermined level at a predetermined target location in the system.

Abstract: A substantially T-shaped fret for a stringed instrument is disclosed which has an elongated stem topped by a triangularly shaped cap.
