Abstract: For monitoring a predetermined level of a liquid in a container an ultrasonic transducer is fitted on the outer surface of the container wall at a measurement point situated at the height of the level to be monitored. The ultrasonic transducer contains a piezoelectric element which generates, when excited by an alternating voltage pulse having a given transmission frequency, an ultrasonic transmission pulse which is transferred via a diaphragm to the container wall and which converts ultrasonic vibrations transferred from the container wall to the ultrasonic transducer into electrical reception signals. The diaphragm comprises on the side facing the container wall protuberances which adjoin the container wall. Between the diaphragm and the container wall a coupling layer is arranged, the thickness of which is determined by the height of the protuberances.

The lower surface together with opposed inner surfaces of the sides form a downwardly depending air entrapment chamber extending longitudinally beneath the lower surface. The chamber is reactive to provide substantial surface effect ram air lifting force on the vehicle in response to forward motion of the vehicle. In addition, the vehicle includes an airfoil spaced above and interconnected with the vehicle body to provide substantial out of surface effect lifting force on the vehicle in response to such forward motion. Further the vehicle vertical stabilizers serving not only to provide vertical stabilization but also to interconnect the airfoil with the vehicle body.

Abstract: A chemical processing centrifugal pump is provided with a triple cartridge seal arrangement including a first seal axially spaced from a pair of concentric seals. The passageway along the pump shaft between the single seal and the radially inwardmost concentric seal is filled with a pressurized barrier inert gas so as to create a gas seal while a barrier chamber defined between the concentric seals is filled with a pressurized barrier liquid. Accordingly, the concentric seals are lubricated by the barrier liquid disposed in the barrier chamber while the inboard seal is lubricated by the fluid being pumped. Optionally, the single seal may be lubricated by barrier liquid if such a pressurized liquid is used instead of the inert gas to fill the passageway.

Abstract: It is an object of the present invention to improve reliability of a battery cell by preventing residual stress in the ting of a sealing gasket so as to provide a sealing gasket which does not crack. The object is achieved by a sealing gasket for a battery cell produced by injecting molten resin into a cavity from a gate which corresponds to a tip of a resin injection nozzle of a metal mold, wherein a ring forming a body of the gasket has an inward protrusion projecting inwardly from an internal surface of the ring and the gate is operatively disposed at a part which corresponds to the inward protrusion. In the sealing gasket so-produced, residual stress is generated in the inward protrusion. Therefore, the strength of the ring does not deteriorate because of the effects of the residual stress and cracking of the gasket can be prevented.

The second sealing ring being sealed with respect to the shaft by means of a bellows unit. One end of the bellows unit being engaged by a first drive band which applies a radial load to the end of the bellows unit forcing it into driving and sealing engagement with the shaft and the other end of the bellows unit being engaged by a second drive band which applies a radial load to the end of the bellows unit forcing it into driving and sealing engagement with the second sealing ring.

Abstract: A recreational personal trailerable vehicle, such as a boat, is provided with a rear brake light. The boat; boat electrical harness, and trailer combination is safer for being towed in traffic. The boat includes a rear-mounted brake light, located in the stern of the boat, activated in concert with the brake lights of a motorized towing vehicle, to warn following motorists that the boat and trailer combination is slowing down. Further, the electrical cable supplying power to the rear brake light is concealed, providing an aesthetically pleasing appearance to the boat. An electrical harness is connected to a power supply on the motorized vehicle and supplies power to both the rear brake light of the boat, and a pair of spaced rear-mounted brake lights of the trailer. Optionally, the rear lights are activated by a transmitter-receiver arrangement that activates a power source electrically connected to the rear light.

Abstract: The invention relates to a CVJ boot in which contact pressure of crest portions closer to a large-diameter mounting portion on the compressed side of a bellows portion is reduced when slant faces forming a root portion of a bending point obtained by the S-shaped bend come into contact with each other, thereby increasing durability.

Abstract: A seal suitable for closing the annular space between the races of an antifriction bearing includes a case which fits into the outer race and a shield that fits over the inner race. Both the case and shield have axial and radial walls that enclose a cavity within the seal. The seal also includes an elastomeric seal element which is bonded to the radial wall of the case and includes a lip which extends obliquely into the cavity and toward the axial wall of the case which it contacts to create a dynamic barrier. The shield also has an outer radial wall that encircles the inner radial wall and extends along the axial wall of the case such that a small gap exists between the outer axial wall of the shield and the axial wall of the case. The outer axial wall of the shield is either out of round or eccentric with respect to the inner axial wall, so that the size of gap varies circumferentially along the gap. As a consequence of this variance, the seal will pump fluent contaminants, such as water.

Abstract: A pipe coupler for interconnecting pipes and components together, for transferring bulk and fluid materials, and useful for connecting sections of pipe-end-to-end. The coupler connects grooved pipe to ground pipe, smooth pipe to grooved pipe or smooth pipe to smooth pipe. Also tees, valves, and pipe sections can be secured together. The coupler has an adjustable bail that can be adjusted to assure a tight seal despite any wear. The coupler also eliminates any gaps that may trap material and lead to cross-contamination of subsequent loads.

So that the axial seal can take up an exactly defined position on the first component, the sealing section is prestressed in a direction towards which the projection extends.

Abstract: A high pressure seal material, such as for a lateral "T" seal of a shear ram blowout preventer, is disclosed wherein the seal material is preferably nitrile rubber and includes uniformly dispersed synthetic, non-cellulosic fibers in parallel alignment to resist rollover action occurring transverse to the applied compressive force by orienting the aligned fibers parallel to the axis of the applied force. The material is made in a milling process that aligns and maintains the alignment of the fibers. The milled sheet is then cut into appropriately shaped pieces. The pieces are rotated 90.degree., plied and cured to make the final material, which curing can be done in a suitable mold so that the final product is in its desired final shape.
