Abstract: A JUNCTION BOX FOR HIGH VOLTAGE GAS INSULATED CONDUCTORS     ASTRACT OF THE DISCLOSURE         Method and apparatus for forming a joint in a high voltage gas insulated electrical system wherein an outer spherical joint member surrounds an inner spherical joint member which is supported from only one of the inner housing conductors.  The inner housing conductor which supports the inner sphere is supported where it extends into the outer housing sphere from a circular insulating member.  The circular insulating spacer and support is rigidly connected to a flanged opening formed on the outer housing sphere.          The inner sphere which is rigidly supported is provided with a plurality of sliding contact openings for engaging other inner conductors of the additional bus sections to be joined.          The outer spherical housing is formed from two hemispheres each of which has an opening formed therein.  The plane defined by the opening into the hemisphere is transverse to the plane defined by the free ends of the hemisphere.  Thus when the hemispheres are joined to form the outer housing sphere by relatively positioning the hermisphere angular variability can be obtained.  That is, when the hemispheres are positioned to define a sphere if they are rotated relative to one another the angle, defined by the center line radii of the openings, changes.  This construction permits a few number of basic hemispherical shaped parts to be utilized to produce junction boxes accommodating numerous angular varia-tions between the bus conductors to be joined.

Abstract: Molding composition suitable forming a shaped article comprises wood particles having about 2 to about 20% by weight moisture based upon the dry weight of the wood particles and a binder composition capable of being crosslinked coated onto the wood particles and present in the proportion of about 0.5 to about 50% based upon the dry weight of said wood particles, the binder consisting essentially of the mixture of an organic polyisocyanate and 0.5 to about one equivalent weight of a polyether polyol based upon one equivalent weight of the organic polyisocyanate, the polyol having a functionality greater than 2; the molding composition contains no catalyst and is used in the absence of a mold-release agent. Consolidation of wood particles into a particle board when accomplished using the molding composition of the invention and metal mold face takes place with substantially reduced adhesion to metal mold parts as compared to a similar use of prior art binders comprising an organic polyisocyanate.  It is thus possible to achieve faster production cycles and thereby effect economies over processes of the prior art in the production of wood particle board which can contain besides binder and wood particles the usual commercial additives to protect the particles board against destruction by fungi, insects or fire.

Abstract: TWO-SPEED DRIVE APPARATUS            Abstract of the Disclosure Apparatus for rotating a driven shaft in the same direction at two different speeds upon rota-tion  of a  drive  shaft in  respective,  opposed directions.  The apparatus includes a sun gear on the drive shaft, a ring gear on the driven shaft, a planet  carrier rotatably  mounted on the drive shaft,  adjacent to  the sun  gear,  one or  more planetary gears  rotatably mounted on  the planet carrier and in mesh with  the sun and ring gears.          An over-running clutch  locks the planet  carrier to the drive shaft when the latter rotates in one direction to thereby lock the  planetary gears to the sun and ring gears  to cause  rotation of the ring gear and the driven  shaft in a first direc-tion at a  first speed.   A sprag prevents  rota-tion of the  planet carrier  relative to a fixed support when the drive  shaft  rotates in  the opposite direction to  thereby allow  rotation of the planetary  gears about  fixed axes  to rotate the ring gear and thereby the driven shaft in the first direction at a second speed.

ABSTRACT                   OBJECT POSITION AND SURFACE DETERMINING METHODS AND APPARATUS           In determining distance between an object and a refer-ence plane in a given volume, a pattern of divergent radiant energy is propagated in a direction irradiating the object and, while the pattern  is translated along an axis in the reference plane, radiant energy reflected from the object is collected at any convenient location.   An output signal is generated in ac-cordance with the repetition rate of the collected radiant energy and is processed to define object distance in a direction out-wardly of the reference plane.   The radiant energy pattern is preferably encoded in a manner facilitating the determination, from collected energy,  of object positional information addi-tional to such outward distance from the energy collecting loca-tion.   Additional positional information may be acquired from line-of-sight information when the collection location is posi-tionally known with respect to  the reference plane.

Abstract: DYNAMIC BRAKE BLENDING FOR AN INVERTER PROPULSION SYSTEM                Abstract of the Invention The stator terminals of an adjustable speed a-c induction motor are connected to a source of d-c electric power by means of an inverter, and a system is provided for blending both dynamic and regenerative electrical braking of the motor whenever it decelerates. The brake blending system comprises a plurality of braking resistors respectively coupled by a corresponding switch in parallel with the power source. The switches are controlled by a control circuit which responds to motor terminal voltage, motor angular velocity and the difference between the commanded and actual motor torques to determine the additional current which the motor could regenerate without exceeding commanded para-meters, When the additional current corresponds to that current which can be absorbed by adding an additional stage of braking resistance, the control circuit actuates a switch to add a stage of dynamic brake resistance. The control circuit also monitors the voltage of the source and removes braking resistance in steps to maintain source voltage within selected limits in order to maximize the current fed to the power source and thus maximize regenerated energy. In an alternate embodiment the control circuit determines the admittance of the source and utilizes the admittance to maintain source voltage substantially constant by removal of dynamic brake resistance in order to force more regenerative current to the source.
