Abstract: ABSTRACT Preparation of granules by making nuclei grow, in a fluidized bed, by causing a liquid material to solidify thereon.  The liquid material is sprayed in the bed upwards, with the aid of a spraying device provided with a central channel through which the liquid material is supplied, and a channel concentric therewith carrying a powerful gas stream, with the liquid material contacting the gas stream and being carried with the gas stream to a dilute zone where the growth of the nuclei takes place, which zone is created by the gas stream and is completely within the fluidized bed. The liquid material is made to come out of the central channel as a virtually closed, conical film, with a thrust exceeding the thrust of the gas stream, and this film is nebulized to very fine droplets with the aid of the gas stream.  In this process a very small amount of high-energetic gas is needed, while no agglomeration occurs in the bed.

Abstract: ABSTRACT         Viscous oil is recovered by a process that increases sweep efficiency and heat and fuel utilization and that reduces well and compression requirements and costs.  Initially, fluid pressure communication is created between two horizontal drainhole wells in a manner such that oil is produced during at least a part of the step of creating fluid pressure communication between the wells.  Fluid pressure communication may be created by practicing hot aqueous fluid (preferably, steam) huff and puff techniques in one or both of the wells.          After fluid pressure communication is created, a combustion supporting gas (probably, air), a fuel (preferably, natural gas) and an aqueous fluid are injected into one of the drain-hole wells.  The fuel is burned downhole in a manner such that hot aqueous fluid (preferably, steam) is formed.  The hot aqueous fluid and hot products of combustion are passed directly into the formation in horizontal line drive fashion.          These hot fluids follow a horizontally wide sweep pattern which increases heat transfer to the inplace on and increases oil drainage into the producing well.  The process is especially useful in permafrost areas.

Abstract: SURVEYING SATELLITE INCORPORATING STAR-SENSING         ATTITUDE DETERMINATION SUBSYSTEM                    ABSTRACT OF THE DISCLOSURE      A system for surveying features of a planet includes a novel attitude determination subsystem.  A satellite includes an earth imaging sensor.  The sensor is alternately directed at the earth and a predetermined star field.  The optical detections are converted to electronic signals by a sensor electronics module.  The outputs of the sensor electronics module corresponding to the times when the sensor is directed toward earth are processed by a signal processor, the output of which is a data stream which permits image reconstruction by a ground station computer. The outputs of the sensor electronics module corresponding to the times when the sensor is directed toward the star field are directed through onboard star detection thresholding electronics. A programmable threshold device selects detections of target stars within the star field.  A star data buffer stores these target star detections for transmission to earth at a convenient time.  This data stored by the buffer is compact star attitude determination data required for accurate gridding of the earth image data transmitted from the signal processor.  In an alternative embodiment, an earth imaging sensor is occasionally pointed at a limited portion of the star field, such special motion being controlled from the satellite.  In both embodiments, compression of star field data is accomplished by means located onboard the satellite.  The compressed star field data is subsequently used to accurately determine sensor attitude.

Abstract: A Contact Sensor For Measuring Dental Occlusion Abstract A contact sensor for detecting points on a grid where the sensor is being contacted on opposing sides by teeth surfaces or other contacting points.  The contact sensor includes two sets of parallel electrodes (54, 64) which are each formed on a thin, flexible supporting sheet (52, 62). The electrodes are coated with a thin, resistive coating (72).  Two such electrode structures (50, 60) are oriented at approximatly right angles to create a grid (88) where the intersecting electrodes cross seperated by the resistive coatings (72).  The resistive coatings may be made from conventional resistive inks and are optionally seperated by a seperation material (70), such as talcum or mesh.  In the absence of an external force, the material between the electrodes sets provides a high resistance between intersecting electrodes.  The novel composition of the intermediate layer (70) results in a structure which provides a "switching" effect such that the resistance between electrodes is very high where there is no external pressure and changes to a comparatively low value at locations where external pressure is applied by two contacting points or surfaces.  The sensor output is dynamic in the sense that the resistance will change back and forth between high and low resistance states as external pressure is repeatedly applied and removed.  The sensor may be made extremely thin and can provide high resolution capable of distinguishing between contact points seperated by 0.050 inches or less. Additionally, the sensor output may be provided by means of a small computer or similar digital processor which monitors the signals from the sensor grid and which provides an ouput which indicates the variation in contacting points with time.
