Title: Inlet total temperature synthesis for gas turbine engines
Inventor: KRUKOSKI LEON
IPC: F02C9/28
Filed: 1987-09-21
Granted: 1991-07-23
Abstract: Abstract Inlet Total Temperature Synthesis for Gas Turbine Engines In a gas turbine engine electronic control system the engine total inlet temperature is synthesized from aircraft Mach number and the nozzle expansion ratio. When the engine is in a transient mode of operation the synthesized value of the total inlet temperature is maintained constant at the value calculated just before entering the transient mode.  The synthesized temperature is used when the actual measured temperature is unavailable or unreliable.

Title: Process for recording semihalftone images

Abstract: TITLE OF THE INVENTION PROCESS FOR RECORDING SEMIHALFTONE IMAGES                 ABSTRACT OF THE DISCLOSURE       A process involving scanning an original linewise and determining the tonal value of each scan dot.  Multiple scan dots are collected into a scan field.  The average tonal value of each scan field is determined by averaging the tonal values of the scan dots of that scan field.  The original is reproduced on a recording medium by individual recording dots that can take the tone value "print" or "no-print".          Several recording dots correspond to a scan field of the original.  The tone value of the scan field can be reproduced almost exactly on the average by printing a specific number of recording dots.  The distribution of recording dots to be printed for a scan field is determined by subdivision of the scan field into the smallest subfields.  In this process, the scan field is subdivided in at least one subdividing step into these smallest subfields, the average tonal value of each resulting subfield being determined so that the number of recording dots to be printed in all subfields of a scan field correspond to the average tonal value of the scan field.     5249k

Patent CA-1312063-C (CA)
Inventor: HAMM HEINER
IPC: B01J20/12
Filed: 1988-04-21
Granted: 1992-12-29
Abstract: Abstract The invention relates to a method of producing an adsorbent where an expanded granular bloating  mineral and calcium sulfate  hemi-hydrate are mixed to form a granulated material where the calcium sulfate hemihydrate  is converted  in toto  into calcium  sulfate dihydrate by the addition  of a surplus of  water, and where  the free water is removed  by drying. It is  desirable that the  pro-portion of bloating mineral be  reduced, that the adsorption  ef-fect be substantially retained and the hardness of the  adsorbent be increased without any additives. This is accomplished by  mix-ing calcium  sulfate hemihydrate  and  bloating mineral  in  such proportion that  a weight  ratio of calcium sulfate  :  bloating minerals > 5 :  1 and up to  10 : 1 exists  in the adsorbent,  in that mixing is  effected by calcium  sulfate hemihydrate and  the bloating mineral  being poured  together into  a tank  and  mixed there together by a stirring  tool to form a granulated  mixture, in that the granulated  mixture after the  addition of the  water and before drying is  allowed a  retention time  of at  least  4 minutes, and in that  the dry calcium  sulfate dihydrate is  con-verted by calcining  at 120  - 150°C  in such  a proportion  into calcium sulfate hemihydrate that the adsorbent has a total  water content of 1 % by  weight to 16 %  by weight. The adsorbent pro-duced in  this  manner  comprises, on  the  one  hand,  open-pore smaller particles which consist only  of calcium sulfate and,  on the other hand, open-pore larger particles where a bloating  min-eral core is coated with calcium sulfate.

Title: Belt sanding machine
Inventor: HUNDEBOL KELD O
IPC: B24B21/16
Filed: 1988-05-25
Granted: 1993-05-18
Abstract: A B S T R A C T            When sanding for instance panelled doors in a belt sanding machine it must be prevented that transverse-ly extending parts (16) are sanded since it would be harmful to sand across the direction of the veins of the wood. A machine according to the invention is therefore provided with a combined sensing and con-trol device which in a simple and effective manner will prevent damage caused by the sanding process by controlling the contact of the sanding belt with the workpiece.            The device  consists of  a  disc  (14,  20)  which is mounted on the sanding equipment. The disc (14, 20) protrudes a distance beyond the sanding position of the sanding belt (15),  in order that the disc will sense the workpiece when  this is moved under the sanding belt. When the disc (14, 20) rolls across a frame piece (16) the sanding belt (15) is pivoted up above the wood,  and when the disc (14, 20) meets a sunken part (18), the sanding belt (15) is pivoted to a non-sanding position.
