Title: Satellite attitude determination and control system with agile beam sensing
Inventor: CHALLONER A DORIAN
IPC: G05D1/08
Filed: 1988-12-20
Granted: 1993-05-18
Abstract: ABSTRACT OF THE DISCLOSURE Agile   (electronically  steerable)   beam   sensing   with associated  on-board  processing,  previously  used  exclusively   for positioning  of   antennas  for   beam  formation   and  tracking   in communications systems, is now also used for satellite active attitude determination and  control.   A  spinning  satellite  (100)  is  nadir oriented  and  precessed  at   orbit  rate  using  magnetic   torquing determined through  use of  an on-board  stored magnetic  field  model (520) and attitude and orbit  estimates (212).  A Kalman filter  (211) predicts parameters (202, 203) associated with a received signal (204) impinging on  the  satellite's wide  angle  beam antenna  (201).   The antenna system measures  the error between  the parameter  predictions and observed values and sends appropriate errors signals (207) to  the Kalman filter  for updating  its  estimation procedures.   The  Kalman filter additionally  outputs  the spacecraft  attitude  error  signals (215) to an attitude control  law (213), which determines commands  to attitude-altering magnetic torque elements (220) to close the control loop via the spacecraft dynamics (230).

Granted: 1992-06-16
Abstract: Abstract of the Disclosure A half-cell of an electric storage cell comprises an electrocatalytic electrode immersed in an aqueous salt solution of potassium and/or other polysulfide anions in high concentration so that the sulfur species which may be electrochemically oxidized or reduced form substantial components of the solution (e.g. at least 20% by weight).  Na+ and OH- salts which limit polysulfide solubility and/or solution stability are not added to the salt solution.  Aqueous KS?2 in the storage cell contains up to 24.5 molal reducible sulfur at 25°C, and up to 34.2 molal reducible sulfur in solution at 50°C.  This high faradaic capacity is readily accessible at high current density with minimal polarization losses.

Abstract: ABSTRACT         A method involving modifications to a conventional electrical motor for the purpose of increasing its resistance to being damaged by the use of water or other liquids in its environment.  The motor is disassembled, and all exposed areas of the stator windings are coated with an epoxy which forms a pliable coating when cured.  The slots between the lamination bars of the stator also receive an epoxy coating.  A layer of epoxy is formed within the junction box against the motor casing, and the epoxy layer has a portion extending into the lead wire opening of the casing and completely surrounds the lead wires passing outwardly through the opening.  The normal bearings for the shaft are replaced with a sealed type bearing, and the endbells of the motor are machined to receive a seal outwardly of the bearings, which seal engages the shaft.  The rotor is sprayed with material which forms a tough resilient film thereover.  Bore holes of a small diameter are made adjacent the peripheral edges of the endbells to provide a passage from the lowermost portion of the enclosure formed by the casing when the motor is in its finally installed position.

Abstract: ABSTRACT OF THE DISCLOSURE    A stack of gel support trays, each of said trays comprising four raised sides and a flat base having an elongate opening along one of the said sides.  At least one gel can be retained on the base clear of the elongate opening with substantially no obstruction to fluid flow across the base towards the opening.  The apparatus includes a system to interlock the trays in the stack to prevent lateral slippage. Each tray in the stack is guided in its stacking so that the elongate openings in all adjacent pairs of trays are at opposite sides of stack.  A cover plate partially encloses the top tray in the stack leaving an elongate opening along the side opposite that of the elongate opening in the top tray.  The apparatus includes a filter capable of absorbing gel grain from a destaining fluid.  The fluid is guided in its flow, leaving the elongate opening of the bottom track of the tray through the filter.  A tank for retaining destaining fluid and for receiving the tray stack, cover plate, filter and fluid flow guide are submerged in the fluid.  an impeller circulates the fluid down through the tray stack, through the fluid flow guide and the filter and up the exterior of the stack to re-enter the stack through the elongate opening of the cover plate.  The invention permits simultaneous destaining of a multitude of gels, both tube shaped and slab continuously.  Maximum contact is achieved between the gel and the diffusion liquid coupled with economical use of space.
