Abstract: METHOD OF FORMING ELASTOMERIC SEAL WITH A BONDED NON-MOLDABLE INSERT MATERIAL HAVING HYDRODYNAMIC SURFACE AND SEAL HAVING A DUST LIP                 ABSTRACT OF THE DISCLOSURE       A method of forming an elastomeric radial lip seal with a bonded solid, deformable, and non-moldable wear insert having a hydrodynamic surface positioned at the sealing lip through compression molding.  Such method embodies the steps of positioning a seal case member coated with a suitable bonding agent on a lower preheated mold core forming a portion of a mold cavity with said core having assembled thereto a negatively imprinted surface having a hydrodynamic fluted configuration at a preselected location; positioning a generally annular deformable and non-moldable solid material treated with a suitable bonding agent on the lower core of the mold situated so as to be in close proximity to the preselected location having the fluted imprinted surface; positioning a generally annular, uncured elastomeric material adjacent the deformable and non-moldable annulus which has a volume greater than the volume of a closed mold cavity; entrapping the elastomer, and deformable and non-moldable annulli and the seal case member by heating and compressing under pressure which is sufficient in magnitude to force portions of the deformable and non-moldable annulus onto the negatively imprint fluted surface by hydrostatic pressure generated by the elastomer being cured, such that a positive imprint is formed on the deformable non-moldable annulus which is generally complementary to the negatively imprinted surface on the seal mold; maintaining pressure and heat for a predetermined period of time to insure curing of the elastomeric annulus and the bonding agents to form a unitary radial lip seal having the deformable and non-moldable annulus bonded to the molded elastomeric annulus material with the latter being bonded to the seal case member; and removing the unitary molded seal member from the mold cavity.  An oil seal having a wear insert in the seal lip and optionally including a dust lip is also disclosed.

Abstract: IMPROVED CIRCUIT INTERRUPTING DEVICE ABSTRACT: An improved circuit interrupting device extinguishes an arc by directing a dielectric fluid at the arc as it is elongated. Elongation is effected by relative movement apart of a pair of contacts between which the arc is established. A reservoir contains a piston which defines a first volume and a second volume. The fluid is held under pressure in the second volume. The reservoir directs the fluid in the second volume at the arc from a port normally closed by a diaphragm. One contact is normally mechanically attached to the diaphragm and is adjacent the other contact which is on the reservoir. Sudden expansion of the first volume, such as by the ignition of a power cartridge, forcefully moves the reservoir relative to the piston and away from the one contact. The seal is torn or cut open to permit the pressurized fluid to flow from the port simultaneously with the piston forcing the fluid from the second volume and the movement apart of the contacts.

Abstract: ABSTRACT OF THE DISCLOSURE         A clothes washing machine which recirculates wash or rinse water from a surrounding tub into a clothes holding basket to reduce the quantity of water required for wash and rinse cycles.  The fill level is controlled by an adjustable pressure-sensitive switch which senses the pressure level at the drain outlet located in the bottom of the tub in order to control water fill levels at the beginning of each wash and rinse cycle.  The pressure-sensitive switch is reset prepara-tory to the initiation of each wash or rinse cycle of the tub by the low pressure existing in the tub bottom after the tub has been drained at the end of each wash and rinse cycle.       In order to prevent false resetting of the pressure-sensitive switch by recirculation flow from the tub, the recirculation pump inlet intake is elevated above the drain outlet by a stand pipe which maintains a sufficient level of water in the tub above the reset pressure level to preclude resetting of the pressure-sensitive switch until the tub is drained through the drain outlet.  The stand pipe is designed to provide an anti-vortex action to minimize the air intake into the recir-culation pump.

Abstract: MOTOR/BRAKE TRANSITIONING FOR AN INVERTER DRIVEN A-C INDUCTION MOTOR               Abstract Torque response of an a-c induction motor control system including an adjustable frequency and adjustable magnitude power source is made more stable during the transition from a motoring to an electrical braking mode by modifying the system characteristics as a function of rate of change of motor flux and torque magnitude during electrical braking.  The control system responses to a torque command signal and a torque feedback signal to generate an error signal which controls the frequency of the excitation supplied to the motor and thus the torque developed by the motor.  During electrical braking this error signal is modified as a direct function of the rate of change of motor flux and as an inverse function of the magnitude of torque developed by the motor. During the transition from motoring to electrical braking, when system instability is maximized, the rate of change of flux is also at a maximum while the motor torque is at a minimum.  Accordingly, the error signal becomes very large in magnitude and rapidly forces the control system and motor out of the transition zone into a more stable operating zone.  Once stabilized, modification of the error signal becomes negligible.

Abstract: LENS PROCESSING METHOD AND APPARATUS       (Abstract of the Disclosure) A chucking method and apparatus for processing a lens blank in a manner requiring only a single mounting of the blank to an associated lens block.  The lens block is mounted to the convex lens blank surface by a hot melt type of adhesive so as to extend outwardly thereof substantially coaxial with the lens blank frame center axis.  The lens blank and lens block are releasably mounted in a chuck associated with lens surface generating apparatus such that the lens blank frame center axis and the tail stock of the generating apparatus are coaxial. The chuck includes means for selectively adjusting and rotating the lens blank relative to the tailstock for accommodating any desired decentration, axis setting and prism prescribed for the finished lens.  Following generation of the desired optical characteristics in the lens blank, the blank and associated lens block are mounted and processed first in surface fining apparatus and then in peripheral edge contouring apparatus.  In these operations, the lens blank frame center axis is disposed substantially coaxial with the associated apparatus tail stocks or chucks.  An adaptor conveniently allows adjusting rotation of the lens blank about its frame center axis in the surface fining and polishing apparatus compatible to any degree of rotation accommodated during surface generation.  Following lens blank edge contouring, the lens block is removed from mounted association with the finished optical lens.

Abstract: Abstract of the Disclosure A surgical instrument useful in closed surgery, as of the knee, in the form of a vacuum shaver comprising an external stationary tube having a side-facing, axially extending shaving port and an internal rotary blade. Radial bearing portions at both proximal and distal ends radially support the blade in shearing relation to the external tube. A vacuum conduit draws fluid and articles to be shaved into the shaving port, and draws discrete shavings through the instrument, while the blade is driven at shearing speeds. In a form particularly suited for closed intra-articular surgery by arthroscopy, the ratio of the axial length of the shaving port to the internal diameter of the passage through which shavings are withdrawn is in the range of 1.5 to 2.0, the shaving blade is of helical form of substantially less than one full turn over the length of the shaving port and the drive motor rotates the blade at speeds in the range of 100 to 200 rpm. The blade is defined by a cut-out in an inter-nal tube, with portion of the full tube defining bearings at the ends of the blade. The external tube, at the distal and proxi-mal sides of the shaving port defines scraping edges, with the vacuum shaving port receiving the resultant scrapings. A distal sideways in the direction of the shaving port upon axial forward motion; serrations on the edge of the shaving port resist axial movement of tissue along the port during shaving action; and both axial sides of the shaving port define cutting edges with the drive motor adapted to drive the rotary blade in either direction at the selection of the surgeon.
