Abstract: Abstract of the Disclosure Enhanced mobility wheelchair is disclosed.   A seat and frame supporting the seat includes a base portion and a seat supporting portion maintained in a space relationship by a plurality of  spacing numbers.   A pair of back rest sup-porting members extend  from the rear base portion of the frame upward past  the seat supporting portion and have a back rest supported therebetween.  A pair of right and left rear wheels are independently and rotatably mounted on oppo-site sides of the frame near the base portion thereof and a pair of right and left front wheels are independently and rotatably mounted near the base portion of the frame at the front  thereof.   Each wheel  includes  a coaxially mounted sprocket and  the same sided wheels are connected with an endless chain over the sprockets to cause the wheels to turn in unison.   The front and rear wheels are sized to permit a user to propel the wheelchair from the rear wheels when in an upright normal position and from the front wheels when in a forward leaning position in either case by grasping and turning the wheels.  By leaning backward the user may shift the center of gravity of the wheelchair backwards to momen-tarily disengage the front wheels and rotate the wheelchair about  the rear wheels.   Optionally the wheelchair may be fitted with a pair of castor wheels to support the rear thereof  with  the  rear  wheels  off  the  ground  to provide improved maneuverability when operating the wheelchair on hard and flat surfaces and to raise the user to a more con-ventional wheelchair height.

Abstract: ABSTRACT OF THE DISCLOSURE                Providing an insulation layer upon electrical conductor by passing the conductor with clearance towards and through an outlet orifice of a die insert as the conductor approaches a die orifice. The degree of concentricity of the conductor within the insulation layer is monitored after extrusion and an eccentrically positioned conductor is moved towards a concentric location by moving the conductor, at a position upstream of the outlet orifice of the die insert, laterally of the feedpath.  This movement effects a change in approach of the conductor to the outlet orifice and influences a change in the angle of departure from the outlet orifice thereby altering the lateral position of the conductor within the die orifice.

Abstract: ABSTRACT        A data communications system is described that covers a geographic area divided into a plurality of non-overlapping zones and includes a general communications controller (GCC), a plurality of channel communications modules (CCM) and associated transmitters and receivers, and a plurality of portable radios. Message signals carrying alphanumeric information are communicated between the GCC and the portable radios by way of a radio channel. Each CCM takes a signal strength measurement every time it receive a message signal from a portable radio. The GCC gathers the signal strength measurements from the CCM receivers receiving the same message signal and computes an adjusted signal strength for each zone. The GCC then selects the zone having the largest adjusted signal strength for determining the location of the portable radio that transmitted the message signal. Whenever the GCC transmits a message signal to a portable radio, the CCM transmitter is used that covers the zone having the largest adjusted signal strength for the last transmission from that portable  radio. Since the GCC can be simultaneously transmitting message signals to portable radios in other zones using non-interfering CCM transmitters, information throughput is greatly enhanced.

Abstract: ABSTRACT An apparatus is desribed which makes possible the precise sputter etching of insulating and other tar-gets, using a finely focused beam of ions produced from a liquid metal  ion source.   This apparatus produces and controls a submicron beam of  ions to precisely sputter etch the target.   A beam of electrons directed on the target neutralizes the charge created by the incident ion beam.   Ultra-precise control  of the etching process is achieved by monitoring the particles that are sputtered from the target surface.

Abstract: CYCLONIC SEPARATOR WITH SCREEN AND BALL CHECK           ABSTRACT          A cyclonic device for separating entrained mat-ter from a fluid stream under pressure includes a vortex chamber having a longitudinally upright cylindrical part and a subjacent frusto-conical part.  Inlet and outlet means are provided for causing the fluid stream to flow first in a downward spiral and then along an ascending vortex.  The entrained matter is separated from the fluid stream by centrifugal and inertial forces acting thereon from the swirling fluid flow.  A cylindrical filter screen is provided concentrically disposed within the chamber and defines an area through which the ascending vortex flows.  The filter screen further separates rela-tively less dense matter from the fluid stream prior to the fluid flowing along the ascending vortex.  A freely buoyant spherical ball is provided which acts as a check valve to close the chamber outlet means when a predeter-mined level of separated matter accumulates in the cham-ber.  The filter screen encloses the ball and loosely constrains the ball to a direction of movement towards the chamber outlet.

Abstract: ABSTRACT OF THE DISCLOSURE          An improved process for liquefying solid carbonaceous materials wherein the solid carbonaceous material is slurried with a suitable solvent and then subjected to liquefaction at elevated temperature and pressure to produce a normally gaseous product, a normally liquid product and a normally solid product.          The normally liquid product is further separated into a naphtha boiling range product, a solvent range product and a vacuum gas-oil boiling range product.  At least a portion of the solvent boiling-range product and the vacuum gas-oil boiling range product are then combined and passed to a hydrotreater where the mixture is hydrotreated  at  relatively  severe  hydrotreating conditions and the liquid product from the hydrotreater then passed to a catalytic cracker.   In the catalytic cracker,  the  hydrotreater  effluent  is  converted partially to a naphtha boiling range product and to a solvent boiling range product.  The naphtha boiling range product is added to the naphtha boiling range product from coal liquefaction to thereby significantly increase  the production of  naphtha boiling  range materials.  At least a portion of the solvent boiling range  product,  on  the  other  hand,  is  separately hydrogenated and used as solvent for the liquefaction.
