Abstract: ABSTRACT OF THE DISCLOSURE A hydrogen-oxygen fueled internal combustion engine is described herein, which utilizes an inert gas, such as argon, as a working fluid to increase the effi-ciency of the engine, eliminate pollution, and facilitate operation of a closed cycle energy system.  In a system where sunlight or other intermittent energy source is available to separate hydrogen and oxygen from water, the oxygen and inert gas are taken into a diesel engine into which hydrogen is injected and ignited.  The exhaust is cooled so that it contains only water and the inert gas. The inert gas in the exhaust is returned to the engine for use with fresh oxygen, while the water in the exhaust is returned to the intermittent energy source for recon-version to hydrogen and oxygen.

Abstract: EXTERNAL PRESSURE-VOLUME                MONITOR FOR ENDOTRACHEAL CUFF                         James O. Elam ABSTRACT    A monitoring system is comprised of an elastomer balloon housed in a spherical perforated cage which is designed to continuously indicate the state of collapse or expansion of the internal cuff or cuffs of an endo-tracheal tube.  This balloon monitor is interconnected in series with the pneumatic channel through which the cuff or cuffs are inflated.  The volume of said monitor-ing balloon may be observed visually with reference to its filling the cage enclosure denoting thereby its state of inflation and therefore, also that of the endo-tracheal cuff.  Calibration of the balloon monitor pro-vides means of accurately observing both the volume and pressure of air in the system.  Therefore, visual in-spection of the monitor indicates by reason of said calibration the prevailing level of pressure in the patient's endotracheal-tube cuff.  Since the maintenance of safe cuff pressures results in a normal position of the balloon, in contact with the cage, electrical and electronic means may be arranged appropriately between the balloon and inner surface of the cage to produce a warning signal in the event of cuff overdistension and an alarm signal in the event of cuff collapse.

Abstract: ABSTRACT OF THE DISCLOSURE         A lightning diverter strip for use on aircraft components has a polyester tape base onto which is bonded by an epoxy a coating or layer of uniformly dispersed powdered aluminum.  A preferred embodiment of the invention includes a light polyester substrate and a uniformly dispersed powdered metal applied to the upper surface thereof and bonded thereto by a suitable flexible epoxy.  Finely powdered aluminum is used as the condcutor metal and is distributed uniformly along the surface of the substrate, in such a manner that a direct current conductive path is not formed.  Thus, the finished strip will have a very high resistance so that it will read essentially as an open circuit to DC voltage.          The particles are dispersed in sufficiently close fashion that the strip is essentially a short circuit to lightning currents and is also transparent to rf energy.  Since the aluminum particles are of small size, very little energy is absorbed in the particles and physical damage due to lightning attachments is held to a minimum.  The particles themselves, since they are very close together, appear to the lightning as a large number of series-connected tiny capacitors which guide the lightning strike to the fuselage.

Abstract: APPARATUS FOR CONTACTING AN AEROSOL        STREAM WITH A LIQUID                               ABSTRACT         A stationary elongated vessel of substantially circular cross section having side walls and end closures is provided with a plurality of rod-like projections rigidly secured to and extending radially inwardly from the side walls at predetermined locations.  A rotatably supported shaft concentrically positioned within the vessel is provided with a plurality of finger-like appendages rigidly secured thereto and extending radially outwardly from predetermined locations on the sides of the shaft.  Support means maintain the concentric position of the shaft and restrict axial movement of the shaft so that the finger-like appendages intermesh with the rod-like projections in non-contacting relationship during rotation of the shaft.  Inlet and outlet means are provided to introduce into and withdraw from the vessel liquids and aerosol streams.  Rotation of the shaft at appro-priate speeds provides effective contact between the liquid medium and the aerosol stream in the vessel.

Abstract: Drawbar for a Trailer Abstract of the Disclosure A drawbar construction for a semitrailer is provided, by means of which the pulling device, such as a tractor, and the trailer form a rigid vehicle combination. This rigid vehicle combination is applicable especially in load-ing timber, whereby an effective lifting crane can be mount-ed on the trailer without the risk of insufficient stability exerted by the laterally extending crane. The drawbar con-struction comprises a rigid drawbar part extending from the trailer and a connection shaft which connects the rigid drawbar part to the pulling vehicle. The rigid drawbar part and the connecting shaft are interconnected by means of a first joint which is turnable only in the horisontal plane. The second joint connecting the connecting shaft to the pulling device is essentially of the same construction as the first joint but turnable only in the vertical plane. The drawbar construction includes preferably also a rotation joint. The supporting effect of the drawbar to the trailer can be essentially increased by means of a double action hydraulic cylinder, which locks the movement of the drawbar at the second joint in the vertical plane.

Abstract: ABSTRACT OF THE DISCLOSURE               The fixing arrangement comprises a heated aluminum plate heating the lower face of a toner-image-bearing copy paper.          The heated plate comprises two transverse ribs extending trans-verse to the copy-paper transport direction and, intermediate them, a sequence of transversely spaced logitudinal ribs, the transverse and logitudinal ribs intersecting to form individual recessed rectangular fields, each of which, when closed off from above by the copy paper, confines air heated by the heating plate to form a transversely extending zone of hot-air air cushions heating the lower face of the paper.  Transversely extending suction channels located upstream and downstream of the hot-air air-cushion zone contain transversely extending rows of suction apertures, for holding the sheet down against the ribs and closing off the in-dividual hot-air air cushions.  At any given instant, the area of the sheet in direct physical contact with the heating plate is minimal, because the crests of the ribs are rounded off to establish virtually zero or line contact with the paper.  The longitudinal ribs can be inclined relative to the transport  direction, to prevent perceivable streaks in the final fused image.

Abstract: The normally provided manually operable switch lever on an electrically drive wheelchair incorporates pairs of switch arms so that additional circuitry can be provided for interconnection with the normally provided left and right wheel drive motors.  This additional circuitry comprises electrical resistances arranged to be connected across the motor leads by the manually operable switch when in an unactuated position for the particular motor in question.  The provision of these resistances across the motor leads when the motors are unenergized results in absorption of back voltage spikes to thereby avoid burning out the switch means, dynamic braking when the motors act as generator as a result of the wheelchair coasting, easier steering control when only one of the motors is energized to effect a turn, and permits the use of permanent magnet type d.c. motors for the left and right wheel drive motors.

Abstract: INVENTOR:   WERNER GLATZ            INVENTION:  APPARATUS FOR ENGAGING AND MOVING INDIVIDUAL             FLAT STRUCTURES, ESPECIALLY PAPER SHEETS OR PRINTED PRODUCTS                 ABSTRACT OF THE DISCLOSURE           An apparatus for destacking a stack of flexible flat structures, especially paper sheets or printed products, compris-ing a suction head which can be moved, by means of a drive device along a closed path of travel.  This suction head is periodically connected, by means of a valve arrangement, with a source of negative pressure, and thereafter is again disconnected from such source.  This valve arrangement comprises a cylindrical valve body attached to a drive shaft of the drive device for the suction head.  This valve body rotates in a valve housing having three housing connections which, viewed in the direction of rotation of the valve body, are arranged behind one another.  The forwardmost housing connection, viewed in such rotational direction, is con-nected withthe negative pressure source, whereas the intermediate housing connection is connected with the suction head.  The last housing connection serves for venting and is connected with the surroundings.  The valve body has a recess extending over part of its circumference and opening in the direction of the circumfer-ential surface of the valve housing.  During its rotation the valve body, by means of its recess initially connects the forward most housing connection with the intermediate housing connection, and thus, the suction head with the negative pressure source.      During further rotation this connection is interrupted and there-after the intermediate housing connection is coupled, by means of the recess, with the last housing connection, so that the suction head is again exposed to atmospheric pressure.  The valve arrangement is synchronized with the movement of the suction head so that at that point in time when the suction head engages with a flat structure this suction head is operatively coupled with the negative pressure source, whereas at the point in time of release of the engaged flat structure the suction head is con-nected with the atmosphere.  The described valve arrangement, even at high rotational speeds of the valve body, allows for a faultless establishment of the requisite negative pressure or vacuum at the suction head.

Abstract: RELOCATE FEATURE FOR AN ELECTRONIC TYPEWRITER                Abstract of the Invention On electronic typewriters which have the ability to record into a small working memory those characters, functions and escapements which are keyed at the keyboard, it is many times advantageous to be able to place the carrier and the print point over a character which has been previously typed without using repeated backspaces. Disclosed herein is a feature for an electronic typewriter which permits the operator to easily align the print point with a character on the page by positioning a reference mark on the card holder or print carrier in relation to a previously printed character and then through keyboard control cause the carriage to shift its position such that the print point is then exactly aligned with the character printed.  The positioning of the carrier such that the reference mark is in relation to the desired print point is accomplished by a backspace operation and the repositioning or causing of the carrier to assume a position immediately over the subject character is accomplished by keyboard control through the electronics of the typewriter to cause the carrier to shift a predetermined distance.
