Abstract: TITLE OF THE INVENTION:           ENDLESS POWER TRANSMISSION BELT CONSTRUCTION AND METHOD OF MAKING SAME ABSTRACT OF THE DISCLOSURE:      Endless power transmission belt constructions having power transmitting contact faces, and methods of making the same, are provided.  The belt constructions comprise an axial tensioning unit, a plurality of lateral stiffening units which are carried by the ten-sioning unit, and friction material carried by at least one of the tensioning unit and stiffening units.  The tensioning unit and the stiffening units are formed of polymeric material that provides an axial and lateral stiffness in excess of that normally provided by poly-meric friction material that normally forms the main body of a belt construction that is reinforced with such a tensioning unit and stiffening units.  The stiff-ening units and the tensioning unit  may be formed of the same material, and may comprise a one-piece con-struction.  Pursuant to one inventive proposal, the friction material is located only at the contact faces of the belt construction, and thereby defines only the contact faces of the belt construction, while the tensioning and stiffening units define all other exposed areas of the belt construction.  Pursuant to another inventive proposal, the friction material has a first portion thereof disposed on the units to define the contact faces thereof, and has a remaining portion thereof disposed on the units to at least assist in securing the first portion to the units . The thickness of the first portion of the friction material is rela-tively thin, and the thickness of the remaining por-tion is no thicker than the thickness of the first portion, whereby a substantially large amount of  the belt construction comprises the material of the units, and a substantially small amount of the belt construc-tion comprises the friction material.

Abstract: ABSTRACT OF THE DISCLOSURE      An isotropic light source produces uniform illumina-tion of a generally planar object to be visually inspected by a microscope such as a P.C. board having an irregular specular surface. Detrimental dark spots which are normally produced are eliminated by providing a skewed beam-splitter between the microscope and the viewed surface, which beamsplitter redirects light directly at the object along or near the optical viewing axis.  The isotropic light source is a light integrating cavity in a first embodiment and a pair of fluorescent lamps in a second embodiment.

Abstract: METHOD AND APPARATUS FOR CONTROLLING    AZIMUTHAL DRIFT OF A DRILL BIT                           ABSTRACT       A method of and apparatus for controlling the azimuthal drift  of a drill  bit in an inclined  well bore  is described.  The method  comprises  prestressing  a drill collar member in torsion to adjust the angle in the horizontal plant that the drill bit makes with the longitudinal axis of the well bore when the drill collar is subjected to the gravitational, axial, and torsional forces of the drilling operation.  The drill collar includes an inner tubular member and an outer tubular member.  The two are held against relative rotation at one end.  The desired torque is placed in the members by rotating the other ends of the members relative to each other in the desired direction.  A splined member engages grooves in the inner and outer surfaces of the members to hold the members in their prestressed state.

Abstract: PIPELINE GAS PRESSURE REDUCTION  WITH REFRIGERATION  GENERATION                           ABSTRACT The high pressure of pipeline gas is reduced to the low pressure of a distribution system with simultaneous generation of refrigeration by passing the gas through two successive centrifugal compressors driven by two turbo-expanders in which the compressed gas is expanded to successively lower pressures.  Refrigeration is recovered from the gas as it leaves each turbo-expander.  Methanol is injected into the pipeline gas before it is expanded to prevent ice formation.  Aqueous methanol condensate separated from the expanded gas is distilled for the re-covery and reuse of methanol.

Abstract: Abstract of the Disclosure A top loading clothes washer adapted for installation under a fixed or stationary upper structure such as a stacked dryer or countertop wherein the washer is pivotable to a forward tilt-out position providing access to its top.  The bottom front of the washer is truncated and the pivot axis which is defined by a stable base is behind the truncation and in front of the center of gravity of the washer.  A latch is provided to lock the washer in its upright washing position.          The latch is releasable by an operator actuated control pro-vided the water level in the tub is below a predetermined level.  Accordingly, forward tilting of a full tub is pre-vented.  Also, the operator actuable control energizes a mechanism which assists in the forward tilting of the washer thereby reducing the pull force required of the operator.          More specifically, a biased hinge creates a backward torsion on the washer to provide increased stability during a spin cycle and the mechansim functions to counteract the torsion.          Further, a washer spin cycle is delayed until at least a portion of the water has been pumped from the tub.
