Abstract: ABSTRACT OF THE DISCLOSURE     This disclosure is directed to a flexible fluid conduit means for directing fluid from a pressure source to a propeller of a ship for minimizing cavitation.  The conduit is formed of split annular rings adapted to be mounted over a propeller shaft, the rings being interconnected to form passages for directing air pressure from the A-bracket through relative rotating seal members and into the body of the propeller.  The disclosed interconnection of the annular rings permits substantial axial and bending movement of the propeller shaft without loss of air.  Being submerged, the conduit is hydraulically balanced such that the force of water pressure tending to open the seal members is always less than the force tending to close the seal members.

Abstract: IMPROVED HIGH CONTINUOUS CURRENT CAPACITY OIL EXPULSION FUSE HAVING MULTIPLE, UNIDIRECTIONALLY VENTED           SEALED BORES           A high voltage oil expulsion fuse having multiple fuse wire bores which vent into opposed chambers which communicate with the oil medium for convective flow of oil through the bores during normal operation is provided wherein a pressure sensitive valve associated with one of the chambers allows only unidirectional venting of deionizing gases from the fuse when a fault or overload occurs causing sequential melting of the fusible elements in respective bores. Oil derived gases generated by the last to melt fusible element vent in both directions from the corresponding bore and the pressure thereof causes the valve to close forcing such gases to flow through the remaining bores to assure complete evacuation of conductive material from all bores upon fuse operation.  In this manner, interruption against a high rate of rise of recovery voltage is assured and delayed failure of the fuse under normal frequency recovery voltage is also prevented. Only a partial segment of each fuse wire is fusible while the remainder is configured to enhance complete evacuation of conductive material from the bores by oil-derived arc generated gases upon operation of the fuse.  The fuse wire bores are formed in a cylindrical dielectric core which in turn is contained within a tubular casing that supports the terminals of the fuse in spaced relation.  Strategically positioned seals are provided to preclude gas leakage from the bores into the interface between the core and the casing such that dielectric breakdown in this area is prevented.

Abstract: AUTOMATIC CASSETTE HEAD DEMAGNETIZER                 ABSTRACT OF THE DISCLOSURE    An automatic electronic head demagnetizer, built into a standard cassette housing (1), includes a demagnetizer circuit (7) designed to produce a vary-ing frequency signal within the audio range whereby the audio system of a standard cassette recorder may be used to produce an audio indication of proper demagnetizer functioning.  The cassette housing (1) is provided with a resiliently mounted pressure pad (5) which forms part of an electrical switch con-nected to a circuitry (7) inside the cassette hous-ing.  When the  cassette housing (1) is inserted into a conventional cassette tape recorder or play-back machine and the "play" button thereof is de-pressed, the machine head moves into engagement with the pressure pad, pushing the latter into the cas-sette housing.  As a result, the pressure pad (5), which is electrically conductive, makes electrical contact with another switch component (6)inside the cassette, housing, thereby closing an electrical switch in the housing.  This activates the control circuit (7) for the demagnetizing inductor.  In response to such activation, a demagnetizing field is established and then caused to decay from an initial maximum amplitude towards zero, whereas the frequency of the demagnetizing field is caused to increase from zero.  After about 5 seconds, the user of the machine presses the "stop" button, thereby causing the machine head to cease pressing against the pressure head (5) and accordingly causing the switch to open and the demagnetizing operation to cease.
