Abstract: WOOD LATHE CUTTING TOOL            Abstract of the Disclosure -A cutting tool for wood turning lathes comprises a unitized elongated bar-like assembly which is operated in a vertical plane without the need for the customary tool rest.          Control and safety are enhanced.  The cutting tool has an adjustable rocker foot at its lower end enabling the height of the tool cutting bits to be adjusted relative to the turning work.  A hit holder containing plural circumferentially spaced bits is locked removably between two body members and it is merely necessary to rotate the cutting tool on its longitu-dinal axis for bringing a new bit into engagement with the work.

Abstract: ABSTRACT OF THE DISCLOSURE   A resilient pneumatic tire which is reinforced by a radially stabi-lized compression element such that the vehicle on which the tire is mounted can be operated safely in an essentially normal manner regardless of the state of pressurization of the tire.  The compression element can be a solid flexible band of high-strength metal or plastic, or can comprise a layered construction having at least a pair of concentric metal bands which have a resilient material sandwiched therebetween.  The compression element is stabilized by radial means such as plies comprising radial cords or wires. The radial elements have freedom in shear with respect to one another and they share radial loads imposed on the compression element and tire such that they reinforce and stabilize the compression element and tire.  Alternately, the radial stabilizing means can be radial rib-like elements cast or formed integrally in the sidewall of the tire.  The radially stabilized band behaves as a supple tensile element when the tire is operated in a pressurized con-dition, but acts as a stabilized structural compressive element for un-pressurized operation.

Abstract: ABSTRACT OF THE DISCLOSURE A harvester for beans and like crop includes a pick-up reel having a width equal to the overall width of the harvester and leading to a first, cleaning, conveyor which terminates at an air passage incorporating a fan for generating a generally vertical air flow.  Where the vertical air passage meets the cleaning conveyor, a rotary valve is provided which permits the passage of the beans and other parts of the crop but prevents or at least restricts the passage of the air flow into the space above the upper run of the conveyor.  The air passage and fan provide a mechanism for separating heavier from lighter elements of the crop delivered thereto from the pick-up reel.  The separating mechanism has a width substantially equal to that of the pick-up reel.  The conveyor and the separating mechanism are pivotally mounted to the remainder of the harvester assembly to facilitate movement of the assembly when it is inoperative.

Abstract: Abstract of the Disclosure A loudspeaker horn has a throat section with a rectangular cross-section to which the driver unit is coupled.          The throat section has side walls joined together by substantially flat digressing top and bottom walls.  The horn has a square mouth which is formed by flat walls forming a bell section which runs between the throat section and the mouth with an angular digression corresponding to the desired horn dispersion pattern, this square mouth assuring equal low frequency directivity control both horizontally and vertically.  A pair of the walls may be additionally flared outwardly at a portion thereof near the mouth to provide improved midrange directivity control.  The use of planar sides between the throat section and the mouth makes for an improved directivity pattern.

Abstract: A B S T R A C T      A fluid laser having a flow channel between fluid inlet and active lasing region which reduces medium heating and resulting medium disturbances.  The channel includes a thin optically transparent, thermally insulating layer directly bordering the medium.  The thin layer rests upon a metallic heat sink, typically cooled, which receives and removes radiated energy from the active region, preventing it from heating the medium.  The thin insulating layer permits the heat sink to be cooler than the medium without causing thermal effects in the medium.  The more homogeneous medium resulting from such treatment contributes to better laser beam quality.

Abstract: BUBBLE DEVICE FABRICATION                         Abstract A single level masking process for producing microelectronic structures, such as magnetic bubble domain devices, which require very fine line widths.  This is a subtractive dry process using a very thin, additively plated mask in order to obtain optimum lithographic resolution.  Use of the very thin plated mask eliminates the need for a thick resist layer which would adversely affect resolution.  In one example, a double layer metallurgy comprising a conductor layer (such as Au) and an overlying magnetically soft layer (such as NiFe) is patterned using a thin Ti (or Cr) mask.  The Ti mask is subtractively patterned using a NiFe mask which is itself patterned by electroplating through a thin resist layer.  The double layer NiFe/Au structure is patterned to provide devices having high aspect ratio, good pattern acuity, and uniform thicknesses, where the minimum feature is 1 micron or less.

Abstract: ABSTRACT OF THE DISCLOSURE A mobile forming station is provided which longitudinally orients plant fibers and compresses them into slugs. A plurality of bonding stations each include a plurality of chambers selectively positionable in alignment with an ejector of the forming station to receive slugs of fibers. Once the chambers are filled with slugs, a bonding substance borne by the fibers is cured to unite the fibers. The chambers are defined by spaced platens which are movable as a unit to se-quentially align the chambers with the ejector of the forming station. The ejector includes a tubular nose which enters the chamber as the fibers are inserted to ensure that the slugs, after insertion, are of uniform density. The platens are con-verged to compress the slugs within the chambers. The platens are mounted on a movable carrier which is displaced away from the forming station each time that a slug is inserted into the chamber against a rear compression wall of the chamber. Means are provided for exerting an adjustable resistance to dis-placement of the carrier to regulate the intensity of the compressive forces, and thus the density of the board. The carrier may comprise a rotary drum carrying sets of platens in circumferentially spaced relation. The forming station can be movable relative to the bonding stations so that as curing occurs at one bonding station, another bonding station is serviced.

Abstract: ABSTRACT         An upgrader variable pressure regulator for internal combustion engines and the like, comprising a vacuum chamber and an associated fuel chamber joined together to support an enlarged vacuum diaphragm on one side, and to encase and support a reduced fuel chamber diaphragm on the other side.  Adjustments are provided in both the vacuum and fuel chambers to limit the travel of both diaphragm assemblies in respective linear direc-tions toward and away from the vacuum or fuel chambers respec-tively.  An adjustable spring in the vacuum chamber urges both diaphragms toward the fuel chamber.  A fuel chamber needle dia-phragm responds to pressures derived from both diaphragms and opens to admit greater quantities of fuel to the fuel chamber.    A second spring in the fuel chamber urges the valve against a needle seat closing the flow of fuel to the fuel chamber when both diaphragms and associated clamp screws travel away from it.          The changes in vacuum applied through a vacuum line attached to the inner manifold of the engine urges the larger diaphragm against its associated diaphragm spring to close the needle valve, when the vacuum is great.  When engine vacuum drops, the large diaphragm spring overcomes the vacuum pressure to urge said diaphragm and an associated clamp screw toward the needle valve, opening it to increase the fuel entering the fuel chamber.         In an alternative embodiment, a single diaphragm is utilized between the fuel and vacuum chambers.
