Abstract: Abstract of the Disclosure The disclosure of this specification illustrates and teaches the use of a self contained breathing apparatus for attachment to a user's back and incorporates a plurality of tanks having a manifold between them that is common to all with a single filling block leading thereto, and a reserve sys-tem mounted at one end thereof.  The reserve system comprises a poppet valve which signals a loss in pressure by closing, after which it can then be actu-ated to open it for supplying the remaining portion of the reserve breathing gas through the manifold.  The system also has a first and second stage regu-lator to provide regulated breathing gas to a user.  The first stage regulator incorporates a dynamically balanced piston which is supported by an O Ring that is deformed through its cross section to provide movement to the valving piston.  The entire system is encapsulated within a package or casing which can be opened along a parting line thereof and which is secured by over-center latches.  The casing has a number of straps- and support members attached there-to forming a harness that a user places around his torso.

Abstract: ABSTRACT OF THE DISCLOSURE              A tracheal tube that may be constructed for either oral or nasal use is preformed as a flexible integral unit from flexible material having a memory so as to return to preformed shape following flexure. The tube has a proximal or machine end portion and a distal or patient end portion interconnected along the length of the tube by an intermediate portion and an abrupt bend portion. The distal or patient end portion and the adjoining intermediate portion merge into each other along the length of the tube and include curvature such that they will positionally conform to the shape of a patient's posterior pharynx and trachea and extend therealong when the tracheal tube is installed for use. The abrupt bend portion interconnects the proximal or machine end portion and the intermediate portion along the length of the tube at an angle substantially no greater than 90°, so such proximal or machine end portion will be located exteriorly of the body opening of the patient and will extend along the face of the patient exteriorly of such body opening when the tracheal tube is installed for use. In those embodiments intended for oral use, the distal or patient end portion extends in the same general direction as the proximal or machine end portion. In those intended for nasal use, the distal or patient end portion extends in the opposite direction.    In both instances, there is a spring-like action from the bend portion toward the distal or patient end of the tube that tends to hold the tube in place without harming delicate tissues. A pair of ports are preferably provided adjacent the distal or patient end of the tube as a safety measure to supply ventilation to both the right and the left lungs during anesthesia should the tube be accidentally advanced beyond the trachea.

Abstract: A B S T R A C T     This is an invention of a pneumatic system for operating and controlling the rotation of turnheads which supply grains and similar materials to selected storage bins.          It consists primarily of a shaft, one end of which is attached to the turnhead, while the other end operates a sequence pro-grammer which operates on cams and limit switches to control the stoppage of the turnhead in a selected position wothout drift.  Rotation to the shaft is provided by a compressed air cylinder which operates by means of a ratchet arm, a one-way rotation cam clutch which is fixed to Raid shaft.  A drum brake which encloses said shaft, is controlled by the programmer, through a series of valves, to lock and release the shaft in selected positions.  Another programmer is provided between the source of the compressed air and the first-mentioned pro-grammer.  This second programmer is equipped with a dial, station numbers, indicator lights, and starter buttons.  Where more than one remote station is installed, generally, the system is repeated at each station except, that the rotating shaft, its programmer and rotation mechanism remain the same.  A variation in the systems consists of replacing the cylinder with an air motor-reducer for rotating said shaft.

Abstract: ABSTRACT OF THE DISCLOSURE         A drum screen for cleaning and classifying wood chips is mounted for rotation.  The screen has apertures of varying size to permit cleaned chips to pass through to be deposited on conveyors located below.  An internal annular spiral baffle extends the full length of the drum and a series of chip lifters are located between the flights of the spiral baffle and project radially inwards from the interior surface of the drum.  Wood chips are fed into the drum at one end and are carried through the drum while being lifted to-wards the axis of the drum by the chip lifters to effect loosening of waste material from the chips.  Cleaned chips pass through the apertures in the drum and chips too large to pass through are car-ried forward and discharged from the end of the drum onto a con-veyor.  A casing surrounds the upper portion of the drum and par-tially encloses the discharge end of the drum.  An air suction de-vice is connected to the discharge end of the drum, drawing off all waste material loosened from the chips.

Abstract: A B S T R A C T           A population device is provided, designed especially for discharging tennis balls for practice purposes, at selected angles of inclination, and at a predetermined, selected velocity.  Employed in the device is a distributor, which is disposed between a hopper and an air pressurizing drum, the distributor being designed to feed balls, one at a time, to the drum, at predetermined intervals. Within the drum, the ball is directed into a receiving tube, being impelled forwardly therein responsive to the build-up of air pres-sure within the drum.  Each ball is temporarily arrested by a radially expandable detent, until the pressure in back of the builds up to a predetermined value.  The ball is thus caused to be freed from the detent, and propelled forcibly out of a barrel dis-posed at an adjusted angle of inclination.           The distributor is disposed between the hopper and drum in such fashion as to cause the spherical objects to be efficiently agitated within the hopper, by passage over the exteriorly cylin-drical surface of the drum while moving to the point at which the objects feed into the drum.  Efficient agitation of the spherical objects within the hopper thus assures to the maximum extent that the distributor will be full charged with said objects.           A trap door, normally closed by air pressure within the drum, is moved with maximum speed to an open position responsive to the free fall of the a spherical object from the distributor into the drum, and moves with equal speed back to a closed position. By holding the open time of the trap door to a minimum, it becomes possible for the device to be interiorly constructed with a simple receiving pipe characterized by an absence of annular induced air flow assemblies and other arrangements which have heretofore been employed.

Abstract: NON-VERTICALLY DISPOSED CYLINDRICAL FIBER BED SEPARATOR            ABSTRACT     A fiber bed separator and method are provided for separating liquids from gases using cylindrical fiber bed elements disposed in a non-vertical position, preferably at an angle of from 0° to 75° from horizontal, and particularly disposed in a substantially horizontal position.  The fiber bed is of fiber of at least 5 micron mean diameter packed to a bed voidage of from about 85 to 98%, the fiber diameter and bed voidage being selected such that at design bed velocity and liquid loading the fiber bed is not flooded and the residual saturation of the fiber bed against gas drag (Rv) on the liquid collected is less than the residual satu-ration of said bed against gravity drainage (Rg).  The gas stream containing the liquid flows from the hollow core of the cylindri-cal element radially through the fiber bed such that the gas and the collected liquid phase flow radially outwardly through said fiber bed and the liquid drains downwardly around the outer cir-cumference of the fiber bed.  In one embodiment said fiber bed separator and method is employed to remove liquid aerosols of sub-micron size and larger from gases.  In another embodiment, said fiber bed separator and method is employed to remove aerosols of sub-micron size and larger from gases in applications wherein the aerosol becomes collected in the fiber bed and does not flow therefrom and for the cleaning of such fiber beds by introducing a liquid into a gas stream upstream of the fiber bed.

Abstract: ENGINE HEATER                ABSTRACT OF THE DISCLOSURE           A simplified, yet highly effective, engine heating apparatus and method is provided which facilitates starting of a cold automotive engine by preheating the engine with hot antiifreeze from a fluid-cooled service engine temporarily coupled to the cold engine; in this manner, the cold engine can be heated prior to attempts at starting so that damage to the battery, starter or other internal components thereof is eliminated.  In preferred forms, the apparatus includes fluid-conveying conduits permanently coupled to the cooling systems of the cold and service engine and normally detachably secured together to define respec-tive closed fluid loops with the associated engines, along with transfer conduits which can be quickly and easily connected through the use of quick-couplers between the disconnected engine conduits to establish fluid communication between the separate engine cool-ing systems.  Running of the hot service engine thus circulates hot antifreeze through the cold engine block and serves to heat the cold antifreeze to permit quick starting of the engine.
