Abstract: LIQUID CRYSTAL DEVICE WITH CHEMICALLY-INDUCED HIGH-TILT ALIGNMENT COATING           Abstract This invention relates to improved liquid crystal devices useful in liquid crystal displays as well as other devices such as optical shutters.  The improvement resides in the use of high-tilt alignment coatings (e.g. 80 and 90) in the device.  High-tilt (e.g., 5-85°) is achieved by chemical treatment of the interior surfaces of a liquid crystal device.  Illustratively, the treatment entails applying a combination of surface coupling agents one of which alone would cause the LC director to make and angle .alpha.1 (e.g., .alpha.1 = 0°; homogeneous alignment) with the surface and another of which alone would yield .alpha.2(e.g., .alpha.2 = 90°, homeotropic alignment), but together they produce .alpha.3 different from .alpha.1 and .alpha.2.

Abstract: PROCESS FOR REMOVING METALLIC CONSTITUENTS FROM DUST OB-TAINED  DURING  THE  ELECTROTHERMAL  PRODUCTION  OF  YELLOW          PHOSPHORUS          ABSTRACT OF THE DISCLOSURE    Metallic  constituents,  especially  heavy metal  con-stituents are removed from dust electrostatically separa-ted from a gas mixture consisting substantially of carbon monoxide and phosphorus in vapor form obtained during the electrothermal  production  of  yellow  phosphorus.  To this end, the dust is initially calcined with continuous agita-tion under oxidizing conditions at temperatures of 300 to 800°C;  next, the resulting calcined matter is mixed with carbon and the mixture is treated at temperatures of 950 to 1200°C under reducing conditions with volatilization of the metallic  constituents;  and the  volatilized metallic constituents are ultimately condensed and separated.

Granted: 1992-01-07
Abstract: ABSTRACT            A ball valve is provided with a blocking mechanism which automatically blocks its control shaft in its respective rotary position between a closure position and an open position when the control movement takes place too rapidly, The blocking mechanism responds to the respective rotary position of an annular inertia body which is rotatably mounted on the ball valve housing and the rotary movement of which effected by spring action is initiated by the rotation of the control shaft and is retarded by its inertia. On adequately slow actuation of the control shaft the blocking mechanism does not become operative. When the actuation is too rapid and could lead to inadmissibly high pressure peaks the control shaft is blocked by the blocking mechanism.

IPC: A61G5/08
Filed: 1988-11-01
Granted: 1992-02-04
Abstract: ABSTRACT         A folding wheelchair with an improved frame and suspension system provides a smooth and cushioned ride over uneven terrain.  The rigid  frame of  the wheelchair has  a  double  "X"  configuration of cross-tubes to improve frame strength without adversely affecting the foldability of the frame.   The suspension system of the wheelchair comprises a pair of suspension wings pivotally mounted to the chair frame by a pivot block.  The rearward end of the suspension wing is rotatably attached to the wheel axle.  The frontward end of the wing engages a spring or shock absorber which, in turn, attaches to the chair frame. The independent suspension of the wheels and relatively long pivotal axis of the wing from the wheel axle provides for better maneuverability  of  the  chair  and  for  a  more  comfortable  ride.  Additional cushioning of the occupant during travel over uneven terrain is provided by the shock-cushioning mechanism of the spring or shock absorber.

Abstract: A hard facing rod is made by mixing particles of tungsten carbide,  particles  of  a metal  binder,  and  a temporary organic binder.  The mixture is pressed, prefer-ably by extrusion, into the form of a rod.   The organic binder is removed and the rod is heated to a sufficient temperature to sinter the metal particles together without melting so that the rod has a residual porosity in the range of from 5 to 20%.  Such a rod is used for hard facing a metal surface in lieu of conventional tube-rods.   The technique permits a high proportion of tungsten carbide relative to the metal matrix and provides uniform distribu-tion of carbide particles in the hard facing.
