Inventor: MACKINTOSH BRIAN H
IPC: C30B29/66
Filed: 1988-05-03
Granted: 1993-05-25
Abstract: Abstract of the Disclosure A control system for controlling the operation of an apparatus for growing tubular crystalline bodies.  The control system comprises a weight sensor for measuring the weight of the crystal, a length sensor for measuring the length of the crystal, a pressure sensor for measuring the pressure inside the crystal, and a controller coupled to the weight, length and pressure sensors for controlling the operation of the crystal growing apparatus.  The controller is coupled to the die heater of the apparatus for controlling the temperature of melt contained in the crucible of the apparatus based on the outputs of the weight, length and pressure sensors.  To ensure the wall of the tubular crystalline body is maintained at a substantially uniform thickness, precise measurement of the weight of the body must be made.  Compensation is provided by this invention for weight measurement errors that are created by pressure fluctations within the tubular crystalline body.

Abstract: ABSTRACT            A tubular heat recoverable article comprises conductive polymeric material and is heated to effect recovery by the passage of electrical current therethrough.  Elongate electrodes are attached on the surface or embedded in longi-tudinal flanges extending along the article.  The flanges also comprise conductive polymeric material but are not heat recoverable, and therefore remain substantially undeformed on recovery other than bending to accommodate transitions. This means that the contact resistance between the electrode and the conductive material of the flange does not increase significantly on recovery.

Abstract: TITLE:  APPARATUS AND METHOD FOR REDUCING EFFECTS OF DRAFT TUBE          PRESSURE FLUCTUATIONS          ABSTRACT OF THE DISCLOSURE Apparatus and method for reducing the effects of draft tube pressure  fluctuations  acting on  a  runner  in a hydraulic reaction turbine or the effects of suction tube pre-rotation acting on the impeller in a centrifugal pump.  A closed surge suppression chamber is mounted about the exterior of the turbine draft tube or pump suction tube.   A plurality of openings are provided about the exterior of the draft tube or pump suction tube communicating with both the interior of the draft tube or pump suction tube and the interior of the chamber near its bottom thereof.  An air inlet is provided leading into the chamber at the top thereof.  In operation, and during operation of the turbine or pump where a rotating helical vortex of water has formed in the draft tube or pump suction tube, water flows from the draft tube or pump suction tube through the openings and into the bottom of the chamber while air is injected into the top of the chamber.  This forms an air bubble in the chamber and forces air through the openings into contact with the lower pressure center of the vortex as it rotates in the draft tube or pump suction tube abating the same.    This chamber also provides an air cushion to attenuate pressure surges which may be provided as the helical vortex rotates through the elbow in a hydraulic reaction turbine draft tube or pump suction tube, and it also provides an air cushion when the water vapor bubbles  in the core of the vortex collapse.
