Granted: 1991-06-25
Abstract: Abstract METHOD FOR SPINNING UP A THREE-AXIS CONTROLLED SPACECRAFT     A three-axis controlled spacecraft (1), typically a satellite, is spun up about its roll axis (20) prior to firing  a  motor  (2),  i.e.,  a perigee  kick  motor,  to achieve  the  requisite  degree  of  angular  momentum stiffness.  Means (21) for imparting rotation about the roll  axis  (20)  are activated  in  open-loop  fashion, typically  at  less  than  full  duty  cycle.   Cross-axis torques   induced   by   this   rotational   motion   are compensated for by means of closed control loops for each of the pitch and yaw axes (30, 40, respectively). Each closed control loop combines a prebias torque (72) with torques  (75,  74)  representative  of position and rate  feedback  information,  respectively.   A  deadband (52)  within  each  closed  control  loop can be widened during the spinup, to conserve fuel.  Position feedback information  (75)  in  each  of  the  control  loops  is disabled upon  saturation  of  the  gyroscope  associated with the roll axis (20).

Abstract: ABSTRACT OF THE DISCLOSURE     A method for applying one or more curved composite elastic strips to a gatherable base material to elasticize portions of the base material comprises elongating a first strip of elastic material and joining a second strip of less elongated material to the elongated first strip in a longitudinally extending and laterally off-set relationship thereto to form a tensioned composite strip of elastic material.  The second strip of material is sufficiently flexible in the plane of the composite strip and is sufficiently resistant to compression so that, upon release of the tensioning forces, the composite strip will curve laterally, i.e., in its own plane.  The tensioned composite strip is adhered to the base material and in one mode of operation the tensioned forces are released only after adhering the composite strip to the base material.  In such case, the base material is displaced somewhat by curving of the tensioned composite strip and may be pleated or otherwise rendered more readily displaceable.  The resulting article comprises one having curved elasticized strips adhered thereto to elasticize portions thereof.

Granted: 1992-02-25
Abstract: Abstract of the Disclosure Fluid Dynamic Pump A fluid dynamic pump, such as an ejector, has a common wall which separates a primary high energy fluid flow passage and a secondary low energy fluid flow passage.  The common wall includes a plurality of adjoining lobes extending in the direction of flow to the outlets of the passages at the downstream  end of the common wall. A lobe on one side of the wall forms a corresponding through on the other side.  The common wall therefore has a wave-like shape at its downstream end. Primary and secondary fluid flow from the through outlets on their respective sides of the common wall and are mixed together rapidly in a mixing region downstream of the outlets.  Secondary fluid is thereby drawn or pumped into the mixing region as a result of this transfer of energy from the primary stream to the secondary stream.  Viscous losses are low during the process.

As the grain filling the bin displaces the paddle, the plunger becomes visible through the end of the sleeve externally of the bin.

Abstract: ABSTRACT      Ammonia is oxidized easily at lower temperatures over platinum containing gauzes bearing a platinum coating having a surface area in excess of about 50 cm2/g.  These gauzes may be heated to a temperature which is sufficient to initiate ammonia oxidation by passing hydrogen in air over these gauzes at temperatures below 75°C, most preferably at temperatures of less than 50°C.

Title: Process for preparing partial polyol fatty acid esters
Inventor: VAN DER PLANK PLEUN
IPC: C11C3/10
Filed: 1987-07-22
Granted: 1992-12-15
Abstract: R 7033(R)-C     ABSTRACT            A process for preparing partial polyol fatty acid esters, e.g. sucrose or sorbitol esters, is improved by (1) mixing the polyol with an alkaline catalyst such as KOH, NaOH or their carbonates, preferably in aqueous solution or dissolved in C1-5 alcohols or ketones at atmospheric pressure and 10-80°C, (2) preparing a mixture of fatty acid lower alkyl esters with an emulsifier, preferably a fatty acid soap, and (3) adding the alkaline polyol solution to the mixture of (2), whereby preferably the solvent is removed during the addition of (1) to (2), e.g. at 60°C and 5 mbar. The reaction is improved  so that partial polyol fatty acid esters with at most half of the polyol hydroxy groups being esterified are formed at 110-145°C within 1-4 hours.
