Abstract: An externally mounted transducer assembly for an ultrasonic liquid level measuring device that utilizes a piezoelectric crystal for generating ultrasonic pulses to be transmitted through a tank or the line containing a volume of liquid. Electrical conductors are formed integrally with the fuel tank for connecting the transducer to other components of the system. The wall of the tank is provided with an arrangement for removably attaching the transducer housing thereto. The tank is provided with electrical contacts that connect to the conductors that are integral with the tank. Also, electrical contacts in the transducer housing are connected to the transducer for providing current thereto. When the transducer housing is attached to the tank, the transducer is thereby connected to the measuring system circuit.

Abstract: A retrofit device includes an elongated displacement element of uniform cross-section. When disposed in an upright position in a chamber of a multi-chamber fluid measuring device, the retrofit device reduces the volume of the chamber and thereby alters the ratio which the volume of that chamber bears to another chamber of the measuring device. The retrofit device may be advantageously employed in a syrup chamber of a multi-chamber measuring vessel used for assessing the volumetric ratio of syrup and diluent components used to prepare a beverage in a post-mix dispenser.

Abstract: A traffic safety control security system is described. Warning lights, signs, and warning flags are connected and secured to the tops of standard traffic cones either with or without the use of cone adapters. One end of a stainless steel aircraft cable connects directly to the traffic control accessories, while the other end of the cable is secured by a removable security disc and padlock within the traffic cone. Interconnecting the accessory and traffic cone together prevents injury to vehicles or individuals nearby if a traffic cone is accidentally struck by a vehicle, or encounters violent weather, causing the accessory to fly loose as a projectile. In addition a chain can now interconnect traffic cones in the system together, preventing theft of the traffic cones and/or accessories. Set up and knock down of the system is consistent with customary traffic safety control procedures.

The degree of movement of the movable scanning element indicates changes in the thickness of the moving fiber sliver. An adjusting element is connected to the movably mounted scanning element and maintains a constant contact pressure of the scanning element against the sliver over the entire measuring range of the movable scanning element.

Abstract: Apparatus and a method of operating any structural configuration of a heater and array of thermocouples to measure with high accuracy, the level of stratified liquids like water and oil or water and gasoline and non-stratified liquids, liquid temperature, and other liquid properties. Simultaneous measurements from all the temperature sensors, before and after heat is applied, will be used to generate accurate temperature profiles for the entire configuration and not just from two adjacent temperature sensors. Different features of the temperature profiles will determine accurately the liquid level, and other liquid properties.

An elongate indicator housing 12 has a chamber 20 therein. A male adaptor 14 has external threads 16 for sealing engagement with the container. A plug 40 is provided at the upper end of the housing 12. Housing 12 includes a transparent wall portion 28 for viewing at least a portion of the chamber 20. A litmus indicator 42 is moveable by a retractable rod 54 from a retracted position within the container to an extended position within the chamber 20 of the housing 12. An outer housing 64 is secured to the upper end of the rod 54, and protects the indicator housing 12 while the litmus indicator 42 is in its normally retracted position.

Abstract: An apparatus and method for providing liquid and gas proof sealing between a metal rod and a plastic housing molded there around. The rod includes a plurality of annular intrusions or protrusions along a length thereof. The plastic material is formed around the rod and the annular intrusions or protrusions. After the plastic material has cooled the rod is translated linearly with respect thereto whereby the annular intrusions or protrusions cause a cold flow movement or disruption of the plastic material. This movement results in a liquid and gas tight sealing between the rod and the plastic housing. The invention herein has particular application for liquid level sensing probes located within gas pressurized vessels. In such examples the rod or rods are used for sensing liquid level by means of electrical conductivity with the sensed liquid.

Abstract: The invention is a flag system for displaying a flag from a hood of an automobile. The primary embodiment consists of a mast with a pin which is inserted into the mast. The pin prevents the flag from creeping up the mast. The flag system is held in position between the hood and car by a tongue. A threaded portion and a threaded nut are located on the mast. The threaded nut is tightened, clamping the tongue onto the car hood.

Abstract: A liquid level sensor based on a closed field circuit comprises a ring oscillator using a symmetrical array of plate units that creates a displacement current. The displacement current varies as a function of the proximity of a liquid to the plate units. The ring oscillator circuit produces an output signal with a frequency inversely proportional to the presence of a liquid. A continuous liquid level sensing device and a two point sensing device are both proposed sensing arrangements. A second set of plates may be located inside of the probe housing relative to the sensing plate units. The second set of plates prevent any interference between the sensing plate units.

Abstract: An apparatus and method for automatic and remote testing of check valves and backflow preventers. Pressure sensors have ports in communication with chambers upstream and downstream from a check valve to be tested. The sensors may be pressure transducers or pressure switches, of single stage, differential, or "dead band" design. Zero or substantially zero liquid flow through the check valve is confirmed either by an existing water flow meter or an auxiliary water flow switch. Upstream and downstream pressures are sampled, and the differential pressure therebetween is compared with predetermined standards and a pass/fail report is rendered. The report may be stored and communicated by hard wire or wireless means, to a remote facility where like information is received from a plurality of check valve sites. One of the three disclosed embodiments teaches an apparatus and method for testing a backflow preventer including a pressure relief valve operating on the reduced pressure principle.

Abstract: A projectile testing system and method is used to assess the projectile fht and test the accuracy of a projectile launcher and projectile in both controlled and uncontrolled underwater environments. The projectile testing system includes a penetrable member that is positioned substantially orthogonal to an expected flight path of the projectile. The penetrable member intercepts the projectile, forming a penetration in the penetrable member. The location of the penetration is used to determine the actual flight path of the projectile. The penetrable member further includes side support members that help keep the penetrable member taut. In an underwater environment, flotation members and anchor members are coupled to the penetrable member, to hold or support the penetrable member taut. The projectile testing system can also include multiple penetrable members positioned consecutively to provide a more accurate assessment of the actual flight path of a projectile.
