Abstract: A DIRECTIONAL-ACTION MECHANICAL VIBRATOR AND A MECHANICAL SYSTEM FOR CONVERTING ROTARY MO-TION INTO RECIPROCATING MOTION ABSTRACT OF THE DISCLOSURE        The directional-action mechanical vibrator of the pre-sent invention comprises a housing which accommodates a shaft carrying a number of inertia masses arranged eccentrically thereon, said shaft being linked to a power drive, and a rod adapted to impart motion to the mass being vibrated which is mounted on a support. The shaft has a crank, and the rod is articulated, through one of its ends, to the crank, and through the other end, to the mass being vibrated, whereas the housing is linked to the support of the mass being vibrated through the hinge joint, the axis of the shaft being parallel to the axis of the hinge joint.      The mechanical system for converting rotary motion into reciprocating one incorporates the afore-claimed vibrator and a power drive kinematically associated with said vibrator and comprising an electric motor with a pulley set on the motor shaft, and another pulley set on the vibrator shaft. The drive pulley is offset with respect to the axis of said shaft in a direction diametrally opposite to the crank a distance appro-ximately equal to the oscillation amplitude of the axis of the vibrator shaft which provides for stabilization of the os-cillation amplitude of the mass being vibrated and adds to the operating reliability of the power drive of the machines that make use of the herein-proposed mechanical system.

Abstract: Abstract:    The invention provides a method of forming an oxide layer on a major surface of a non-aluminum containing Group III-V compound body used in integrated circuits. First an Al-containing Group III-V compound layer is formed on the major surface and then the Al-containing layer is thermally oxidized for a time period sufficient to convert said layer to an oxide layer, the oxidizing being essentially self-terminating at the surface.  This method provides a highly controllable and reproducible process for growing oxide layers that exhibit extremely sharp and smooth interfaces and precisely controlled layer thicknesses.

Abstract: ROTARY SWEEPING BROOM                 Abstract of the Disclosure A rotary broom for street sweepers and the like includes a central core.  A coiled sweeping brush means has one end affixed to the core and is helically wound around the core.  The turns of the brush means are free to move on the core and the winding direction of the brush means is coordinated with the direction of rotation of the broom so that rotation of the broom on the street produces a circumferential movement of the brush means about the core which tightens the brush means on the core.  The brush means may comprise a first coiled sweeping brush with one end affixed to the core and helically wound around the core in a first winding direction, typically toward the center of the core.  A second coiled sweeping brush has one end affixed to the core and is wound in the opposite direction of winding toward the center of the core.  The inner ends of the brushes may be coupled to a clip which permits the slack removing, circum-ferential movement about the core while restraining the ends for other movements together.

Abstract: PARAHYDROGEN RAMAN TRANSITION AND METHOD                        Abstract A coherent tunable narrow band IR source in the vicin-ity of 16 um is achieved by four-wave parametric mixing in parahydrogen.  A pair of colinear laser beams, one from a narrow band CO2 laser, and a second from a multiline laser with output of wave number signifi-cantly below 14,400 cm.-1, is focused in a parahydrogen containing cell.  The multi-line laser beam drives a Raman process in the cell.  The narrow band CO2 input beam mixes with this driver beam and the Stokes wave resulting from the Raman process to produce a 16 um output beam.  Tuning of the CO2 laser allows tuning of the 16 um radiation emitted by the parahydrogen cell.

Abstract: DENTAL HEALTH TOOL AND METHOD OF                   DISRUPTING PLAQUE            ABSTRACT OF THE DISCLOSURE:        The disclosure teaches a new method of dental plaque removal and the structure of a brush bristle which enables the method most efficiently.  A filament loop of contractable material such as polypropylene is caused to shrink as it is being attached to a base.  The loop exhibits an extra-ordinary contraction wherein the loop is not merely reduced as expected, but by the process of this invention it contracts into tightly adjacent filaments with a tight return loop.          The resulting bristle not only solves the vexing problem of proper bristle polishing, but as an unexpected additional value, exhibits a greatly improved capability to actually scoop away tooth deposits such as plaque.

Abstract: FIBER OPTIC CONNECTOR      ABSTRACT This invention relates to fiber optic connectors.  Connectors are known in which the optical fiber end to be connected is held in a guiding sleeve which can be shifted in a transverse direction by means of a bolt in one wall of the connector.  However, alignment of the ends of the optical fibers being connected to those of a mating connector requires manual mechanical adjustment.  Another fault of the prior art is that the ends of the optical fibers are unprotected when the two mating connector parts are disconnected. The present invention provides means by which an automatic ad-justment of the alignment of the ends of the optical fibers is made possible, and other means by which the ends of the optical fibers are protected when the two mating connectors are separated.  An optical fiber holder resiliently mounted within a connector housing permits limited displacement of the optical fibers contained within the holder, in directions perpendicular to the longitudinal axis of the optical fibers.  Any misalignment with with the optical fibers of a mating connector is thereby automatically corrected.  In another aspect of the invention, a cover which is normally closed protects the ends of the optical fibers when the connectors are disconnected from their mating connectors.  The cover is displaceable so that when the connectors are brought into close proximity to one another, the cover is opened exposing the ends of the optical fibers.

Abstract: MODULAR OFFSET LITHOGRAPHIC PRINTING TOWER            Abstract of the Disclosure A low cost, variable, modular, web-fed offset lithographic printing unit or tower is disclosed which allows significant economies in production and maintenance, and can be easily and quickly modified in the field using interchange-able modules so as to vary printing characteris-tics.  The printing tower, in the straight-through variable perfector form thereof, is preferably provided with a printer module having upper and lower web-printing blanket rollers; in addition, the tower has corresponding upper and lower inker modules for the respective blanket rollers.  The upper inker module is mounted for pivotal movement about a horizontal axis so that it can be shifted between a normal inking position over the printer module to a retracted, printer module-clearing position allowing removal and/or replacement of the printer module by essentially vertical shift-ing of the printer module.  By virtue of modular construction, the supporting sidewalls for the separate tower modules can be of varying thick nesses sufficient for support of the intended module components, and thus the necessity of uniformly thick, expensive tower sidewalls, and the manufacturing problems associated therewith, is completely avoided.  In addition, the modular tower permits mass production of certain univer-sally used modules to lower costs, and also allows the user to stock extra and/or different tower modules to facilitate field repair or alteration of the tower.

Abstract: MODULAR, WASTE COLLECTING AND   DRAINING FLOOR APPARATUS               Abstract of the Disclosure An improved construction is provided for slotted, waste draining floors such as commonly employed in live-stock enclosures.  The apparatus employs spaced, parallel, elongate assemblies, which are preferably formed of metal extruded in generally "T" shaped cross-sectional configuration (or in generally "pi" shaped cross-sectional configuration for heavier loads) to present a slotted floor, in combination with slotted waste collection and drainage pipes, which are preferably formed by longitudinal cutting of ordinary plastic pipe, within the chambers between the assemblies.  The assemblies and pipes may be made to any desired length, and the modular nature of the construction permits forming a floor of any desired width.  An important advantage of the apparatus is that, since it provides for the collection and drainage of waste materials by virtue of its own simple combination of elements, it eliminates the need for an underlying waste collection pit and can be mounted either directly atop a solid sub-floor or in tiered fashion upon elevated support beams without pass through of waste materials to an underlying compartment.  A particularly advantageous aspect of the improved floor construction is the manner in which the floor-presenting assemblies and the waste handling pipe or trough elements are mechanically inter-coupled to enhance structural strength and stability, as well as the simple and effective way in which that is accomplished.

Abstract: ABSTRACT OF THE DISCLOSURE    Clamping apparatus is provided for holding thin flexible printing plates in position on a press cylinder.  In certain preferred embodiments, shim members are attached to the outer periphery of the press cylinder for accurately radially posi-tioning the printing plates with respect to the surface of the press cylinder.  A clamping assembly is provided separately from and at a spacing from the shim members in a gap formed between facing edge portions of the shim members for releasably clamping one edge of the printing plate while the other edge of the prin-ting plate is engaged over one of the edge portions of the shim member.  The shim members and the clamping assembly are indepen-dently and separately attachable to the press cylinder so that the shim members can remain in position while printing plates are exchanged, as well as during removal and/or adjustment of the clamping assembly.  In order to accommodate reversal of the direction of clamping of the printing plates, a pair of symmet-rically arranged lock bars are hingedly mounted for selective engagement with detent portions of the printing plates.  The detent portions in one set of preferred embodiments for use with very thin plastic plates are formed as apertures engage-able over pin sections of the lock bar.  The detent portions in another set of preferred embodiments are formed as bent back edge portions which engage over a smooth lock bar.  The shim members are provided with symmetrical facing undercut smooth surfaces for anchoring the leading edge of the printing plate, the trailing edge being engaged by one of the respective lock bars.  The trailing edge of the printing plate is provided with a central recess for accommodating insertion of a tool to rotat-ably move the lock bar out of clamping engagement.  The leading edge of  the printing plate is provided with centering apertures engageable with a retaining spring clip clamped in position on the press cylinder by a base member of the clamping assembly.

Abstract: TITLE OF THE INVENTION   valves and Breathing Apparatus Incorporating Such Valves ABSTRACT OF THE DISCLOSURE       A valve, notably for use as a demand valve in breathing apparatus, has a pressure-responsive diaphragm coupled to a separate control member which lies in the path of a jet of gas which vents from a control chamber through an orifice, gas being continously supplied to the control chamber.         Deflection of the diaphragm in response to pressure changes in a second chamber caused by inhalation and exhalation of the user of the apparatus pivots the control member towards or away from the jet orifice to control the rate of venting from the control chamber and thereby vary the pressure within the control chamber.  Flow of gas through the valve to the user of the apparatus is controlled by a flexible disc which in turn responds to the pressure in the control chamber.  By employing a separate diaphragm and control member the former can be optimised for pressure-response while the latter can be optimised for valve-regulation by interaction with the gas jet from the control chamber.
