Abstract: ABSTRACT OF THE DISCLOSURE An improved winch-type device for establishing and maintaining tension in a tie rope, cord, or cable is disclosed. The novel device is self-locking and does not require a ratchet or other locking mechanisms as used in convention winch devices. The device comprises a reel consisting of two end discs which are joined together at their centers by a spindle, i.e., an elongate shaft. The end discs of the reel are supported by a pair of bearing members in which the bearing faces thereof substantially enclose and make sliding contact with the perimeters of the respective discs. The bearing members are interconnected by a connecting member extending from one of the bearing members to the other so as to hold the bearing members in fixed position about the respective discs. A crank member is associated with one of the end discs for rotating the reel within the bearing members. Means are provided for attaching a tie rope, cord, or cable to the spindle of said reel so that the rope, cord, or cable can be wrapped around the spindle when the reel is rotated, to establish and maintain tension in the rope, cord, or cable. Frictional forces developed between the end discs of the reel and the bearing members render the tensioning device of this invention self-locking, i.e., after the reel has been rotated by the crank member to develop tension in the rope, cord, or cable attached thereto, the crank member can be released and the reel will remain stationary, thereby main-taining tension in the rope, cord, or cable.

Abstract: ABSTRACT OF THE DISCLOSURE            The invention relates to a method and an apparatus for agglomerating and precipitating suspended matter out of a gas using centrifugal acceleration within a treatment chamber distinguished by an inner cylindrical inlet tube through which the contaminated gas is led in a downward path and an outer circumscribing barrel through which the cleansed gas is led in a spiralling upward path.          The inlet tube and barrel are mounted over and relative to a lower water filled reservoir or contaminant collection chamber.  The gas exits from the  inlet tube through an accelerator in the form of an adjustable venturi throat defined by a shroud arrangement vertically aligned with and spaced from the inlet tube and by which the downward flow direction of the gas is reversed as the gas aspirates water and passes upwardly through and out of the venturi throat and into the passageway defined by the inner inlet tube and the outer barrel.  The upwardly moving gas is spirally deflected by means of spaced deflector plates outboard of and peripherally of the inlet tube and shroud so that a swirling motion is imparted thereto.  The resultant force throws any heavy moist particles against an annular demist-ing collar which extends horizontally and radially outwardly into the path of the gas moving through the accelerator.          The heavy mist impinging on the collar causes deflection thereby against the barrel wall whereby it is removed from the effluent and flows downwardly returnably to the water reservoir.  The lighter mist-free gas bypasses the collar and moves in swirling fashion upwardly toward the clean gas outlet located within the upper part of the barrel, the gas picking up heat from the innermost inlet tube in its ascent and thereby assuring its mist-free condition upon reaching the gas outlet.

Abstract: TONER CONCENTRATION CONTROL APPARATUS                Abstract of the Disclosure A xerographic copying apparatus having a developer operable to present a two component developer mix, i.e. carrier and toner, to the photoconductor's latent electrostatic image, and apparatus for automatically adding virgin toner to the developer as the toner concentration is depleted as a result of toning the photoconductor's image over a period of making a number of copies.  Once the need to add toner is indicated, a known, unit quantity of toner is added to the developer.          Immediately thereafter, the ability to sense toner concentration is inhibited until the next two photoconductor images have been toned.  In the event that low concentration is sensed immediately thereafter, another unit quantity of toner is added, and sensing is again inhibited for the two-copy interval.          In the additional event that low concentration is sensed seven consecutive times, each time being separated by a two-copy inhibit interval, a failure latch is set and further operation of the copying apparatus is inhibited.  That latter event may be caused by toner exhaustion, failure to feed toner properly, or failure of the concentration sensing means.

Abstract: ABSTRACT OF THE DISCLOSURE              A differential pressure sensing device is fully implanted in the body of a patient to monitor internal pressure such as intracranial pressure.  A movable element in the sensor communicates with the internal pressure of the body to be measured on one side and the atmospheric pressure on the other, the latter communicated through the intact skin and a nearly coplanar membrane.  The movable element's differential pressure dependent displacement changes a physical characteristic of the sensor, such as the resonant frequency of a tuned L-C circuit, and the change is detected external to the body by a radiating detector system, such as a frequency swept radio frequency oscillator, by which the internal pressure is read out.

Abstract: MARINE PROPULSION CONTROL SYSTEM                     Abstract of the Disclosure There is disclosed a control system for the air actu-ated ahead and astern clutches and the engine speed governor of a marine propulsion system. Upon actuation of a throttle lever controlling a throttle valve, a selector valve is first actuated to operatively connect one or the other of the ahead or astern clutches to the control. Further movement of the throttle lever causes a relay valve to supply air at a pres-sure proportional to the throttle position to a main control valve which passes such air pressure to the selected clutch until a first control pressure is reached. Thereafter, air from the supply is supplied at a programmed rate to the sel-ected clutch to continue inflation of the clutch until a second control pressure is reached whereupon a boost valve is actuated to connect full  supply air pressure to the sel-ected clutch. A governor control valve also receives the air output of the relay valve proportional to throttle position.          When the pressure within the selected clutch exceeds the level of a biasing spring within the governor control valve, the governor valve opens and the air output proportional to throttle position is applied to the engine speed governor.          Once open, the governor valve is subjected to a counter-biasing pilot pressure equal to its output pressure so that the valve will close whenever the pressure applied to the speed governor plus the biasing pressure of the spring in the governor valve exceeds the pressure of the air within the selected clutch.

The fitting includes a nipple, a sleeve and a socket.  The nipple has a tubular part which is inserted into the end of the inner tube.   The sleeve includes an insert part that is positioned between the end of the inner tube and the wire, and the socket is located around the tubular part of the nipple and around the sleeve.  The socket is attached to the nipple, and the end of the wire reinforcement is clamped between the socket and the outer surface of the sleeve.  The and of the inner tube is located in a pocket formed between the nipple and the insert part.  During assembly of the fitting, the socket causes deformation of the insert part of the sleeve and initial com-pression on the end of the inner tube which is in the pocket.          This initial compression combined with barbs formed on the insert, serve to secure the end of the tube in the pocket.          Fluid pressure internally of the hose serves to activate a gland seal formed by the end of the tube in the pocket.  Tapered surfaces of the socket and the insert part cooperate to deform the insert part in an advantageous manner.
