Abstract: A combination highway and rail vehicle having front and rear sets of tires and front and rear sets of rail guide wheels. The front guide wheels are carried by a wheel suspension which swings the guide wheels into contact with the rails forwardly of the front tires and simultaneously raises the front tires, against the force of tire suspension springs, to positions above the rails. As a result, the front tires, which may be wider apart than the rails, are lifted out of the way, and the rear tires of the vehicle are required to carry a substantially greater portion of the weight of the vehicle plus its load, thereby increasing the traction between the rear tires and the rails.

Abstract: A new class of high-power lasers capable of high efficiencies in the visible and shorter wave lengths is taught, employing an excitation energy transfer mechanism from a pumped noble donor gas, such as Argon, to an acceptor lasing gas, preferably Nitrogen. In particular, such an Argon/Nitrogen laser exhibits a very useful, unique output wave length at 3577A, this being derived from a mixture of Argon, predominantly, with a minor percentage of Nitrogen, excited by a relativistic electron beam of relatively high current density. Such gas lasers with a noble gas as donor offer great promise, using high electrical conversion. efficiency of the noble donor gas with a non-radiative energy transfer to the lasing gas.

Abstract: A push arm assembly for eccentrically operating a ratchet gear by means of a driving pawl to rotate an unloader arm in the bottom of a silo or the like. Directional change of the driving pawl is accomplished by withdrawing the driving pawl into its housing and rotating it 180.degree. and then releasing it to place the pawl in engagement with the ratchet to drive the latter in the predetermined forward or reverse rotation. The driving pawl also can then be rotated 90.degree. into a position out of engagement with the ratchet when rotation of the unloader arm is not desired. A holding pawl is also employed in conjunction with the driving pawl to restrain the ratchet during the period of oscillation when the driving pawl disengages the ratchet and recedes to engage the next tooth on the ratchet. Directional change of the holding pawl and disengagement from the ratchet is accomplished in the same manner as the driving pawl.

Abstract: Magnetic recording tape having a backing of biaxially oriented polyethylene terephthalate film containing small amounts of at least two types of structurally dissimilar minute polymeric particles. One type of particle is selected from the class consisting of polypropylene, styrene-acrylonitrile polymer, nylon and incompatible polyesters and the other from the class consisting of polymers of lower olefins. The tape, which has a microscopically irregular, scratch-resistant back free from large protruding particles, is especially adapted for use in instruments and computers, where the resultant dropout incidence is extraordinarily low. A further refinement employs as a backing a two-layer coextruded film, the back layer containing the polymeric particles and the face layer containing no particulate matter and hence being extremely smooth. When the smooth surface of the face layer of such a thin two-layer film is metallized, a mirror-like appearance results; the film can, however, still be handled in roll form.

Abstract: A tool holder for use with a die profiler assembly utilizing a power device imparting reciprocating motion to the holer is provided. The holder employs a flexible wand attached at one end to the power device; an apertured tool-holder blade is secured to the opposite end of the wand for engaging a finishing tool such as an abrasive stone mounted at a desired angle to the wand axis. A retaining clip assists in maintaining the stone in assembled relation with the wand and blade. In a modified holder construction, superimposed, longitudinally adjustable, apertured wands may be employed to hold the stone at a desired angular disposition without the need for a retaining clip.

Abstract: A rotatable airfoil projectile comprising a hollow closed circular ring wing surrounding a central open area with a non-lethal riot control agent positioned within the hollow ring. The projectile consists of an aerodynamic lifting body of a thick ring wing geometry which uses spin imparted to it from a launching means for its gyroscopic stability. The combination of aerodynamic stability characteristics and high spin rate (i.e. above 2,000 rmp) results in a flat trajectory and extended range capability.The projectile ruptures on impact due to centrifugal and impact forces to distribute the non-lethal riot control payload about the target area. The sub-sonic launch velocity avoids bodily harm due to impact with a person even at point-blank range.

Abstract: A microelectronic LC circuit capable of being tuned to a desired center resonant frequency, comprising a trimmable capacitor, a principal fixed inductor and a printed trimmable inductor having an inductance which is small compared to that of the principal inductor. The printed inductor is one which is capable of having its inductance raised by trimming. In some cases, the fixed inductor can be omitted.

Abstract: A continuous flow of gas plasma is supplied to a space at a very low pressure in which the object to be sterilized is located. Cool plasma of a suitable gas such as argon is produced continually by being subjected to a radio-frequency field. Complex shapes such as capillary passages through a blood oxygenator can be sterilized by passing the gas plasma through them. The exterior of objects to be sterilized can be subjected to gas plasma in a space at a very low pressure either confined or unconfined. The space may, for example, be a packaging envelope, and subsequent to sterilization such envelope can be evacuated and collapsed onto the object to preserve its sterile character.
