Abstract: AN UNDERWATER SONAR TRANSDUCER UTILIZING A UNITARY OR HOMOGENEOUS CYLINDRICAL PIEZOELECTRIC CERAMIC ELEMENT HAVING TWO SETS OF ELECTRODES FIXED THERETO AT SEPARATE AXIAL REGIONS OF THE PIEZOELECTRIC CYLINDER ELEMENT. ONE SET OF ELECTRODES PRODUCES ORTHOGONAL DIRECTIONAL BEARING RELATED VOLTAGES, AND THE OTHER SET OF ELECTRODES PRODUCES OMNIDIRECTIONAL BEARING RELATED TO VOLTAGES.

Abstract: A damper for use in submerged hydrophone suspension systems including an elongated mass cylinder defined by a tube of flexible synthetic plastic film utilizing a check valve located at each end permitting water to enter the tube and preventing egress. Additionally, each tube end is provided with a disk transversely disposed to the tube length and of a diameter substantially greater than that of the tube to provide drag and hydrodynamic mass damping. The tube and disk are of a configuration to eliminate vortex shedding and the entire damper assembly is capable of being folded and packed within a concise configuration prior to deployment.

Abstract: Apparatus for automatically applying a lubricating liquid to the beads of an unmounted pneumatic tire prior to the mounting of the tire upon a wheel. The apparatus includes a rotating roller having a periphery coated with the lubricating liquid which is axially inserted through the tire opening and raised to support the tire upon the roller by its beads wherein rotation of the roller applies the lubricating liquid to the tire beads. The apparatus is automatically operated, and preferably, forms a part of an automated wheel assembly system. Axial and vertical movement of the roller is accomplished by a roller supporting linkage system.

Abstract: THE INVENTION PERTAINS TO A FLUID PRESSURE SENSING MEMBER UTILIZED WITH A PRESSURE TRANSDUCER WHEREIN THE PRESSURE SENSING MEMBER IS OF TUBULAR CONFIGURATION AND INCLUDES SPIRALLY FORMED FLUTES WHEREIN A PRESSURE DIFFERENTIAL ACTING UPON THEIR THE INTERIOR OR EXTERIOR WALL OF THE SENSING MEMBER CAUSES A TWISTING AND ANGULAR DEFLECTION OF THE MEMBER ABOUT ITS LONGITUDINAL AXIS PROPORTIONAL TO THE PRESSURE DIFFERENTIAL. THE FLUTES ARE FORMED IN THE MEMBER BY A DEFORMATION OF THE MEMBER MATERIALS, USUALLY INWARDLY, RATHER THAN THE FLUTES BEING FORMED BY THE TWISTING OF A NONCIRCULAR TUBULAR BLANK AS IS KNOWN.

Abstract: A TRANSDUCER FOR UNDERWATER ACOUSTIC SENSING SYSTEMS WHEREIN THE TRANSDUCER COMPRISES HOLLOW PIEZOELECTRIC CERAMIC CYLINDERS ACOUSTICALLY ISOLATED AND STACKED IN A VERTICAL INTERSTITIAL ARRAY. THREE TRANSDUCER SECTIONS ARE UTILIZED HAVING AN OUTPUT LEVEL AND RELATIVE POLARITY RELATED IN ACCORDANCE WITH THE DIRECTION FROM WHICH THE ACOUSTIC SIGNAL BEING RECEIVED ARRIVES. ONE OF THE ACOUSTIC RECEIVING PATTERNS IS OMNIDIRECTIONAL, AND THE OTHERS ARE SINECOSINE DIPOLE PATTERNS WHICH HAVE THE CHARACTERISTICS OF OUTPUT LEVEL VARIATION WITH BEARING. THE OMNI OUTPUT PROVIDES AN AMPLITUDE AND PHASE REFERENCE FOR COMPARING THE AMPLITUDE AND POLARITIES OF THE TWO BEARING-SENSITIVE SIGNALS. THE RESULTANT THREE SIGNALS, AND COMPASS INFORMATION CONSTITUTE THE PRIMARY OUTPUTS OF THE SENSING SYSTEM WHICH ARE TRANSMITTED TO SUITABLE DECODING AND RADIO TRANSMISSION APPARATUS.
