Title: Cleaning unit
Inventor: HEATH JAMES E
IPC: A47L15/00
Filed: 1987-06-05
Granted: 1993-03-16
Abstract: ABSTRACT OF THE DISCLOSURE     A cleaning unit for the preparation of cooking articles to be cleaned exposes  the articles to radiation energy, heating the articles to a temperature in excess of about 700°F and preferably about 740°F.  Energy is provided by infrared radiation lamps disposed to one side of the article to be cleaned, with this energy heating the article to effect burning and/or charring of any food residue.  This unit is particularly advantageous in cleaning of aluminum broiler plates used to cook meats.  Such broiler plates are difficult to clean by conventional techniques.  The food contaminates, when subjected to the high temperatures, change in structure and are easier to remove after treating.  A cooling air flow over the article to be cleaned maintains the heating chamber and atmosphere several hundred degrees Fahrenheit below the treatment temperature.

Title: Method and apparatus for temperature control of heating and coolingplants
Inventor: VIESSMANN HANS
IPC: G05D23/19
Filed: 1987-07-16
Granted: 1992-02-25
Abstract: ABSTRACT OF THE DISCLOSURE     The present invention relates to a method and an apparatus for controlling the temperature of heating and cooling plants having a heat or cooling source of adjustable rated temperature via particularly a microprocessor-controlled control system.  The actual outside temperature determined by an outside temperature sensor is not used as reference temperature but instead there is used a theoretical mean outside temperature stored at specific scanning times of a calendar year.  Said theoretical mean outside temperature is stored in the form of a characteristic diagram in a non-erasable memory for one or several climate zones.  By correction of the stored values of the theoretical mean outside temperature particularly on the basis of the thermal load of the system determined via the rate of heating or cooling of the heat or cooling source as well as perhaps the correction of the daily course of the outside temperature on the basis of likewise stored values the rated temperature of the heat or cooling source can be so controlled that it corresponds to the actual outside temperature conditions without requiring an outside temperature sensor.  With regard to its construction, installation and putting it into operation as well as from the economic point of view the apparatus is particularly advantageous.

Title: Apparatus and method for high density interconnection substrates using stacked modules
Inventor: SANKAR N GOWRI
IPC: H05K3/46
Filed: 1987-08-14
Granted: 1992-12-22
Abstract: ABSTRACT         In order to provide for interconnection of a plurality of electronic components, thin sheets of an appropriate dielectric material have holes drilled therethrough.   The holes  are  then  filled with  a conducting  material  and  the  surfaces  of  the substrates  are  lapped  to  insure  smoothness.   A conducting  pattern  (i.e.  of  conducting  traces)  is formed  on  the  surfaces  of  the  dielectric sheets.          Conducting regions are also formed on the dielectric sheet surfaces.  A first sheet of dielectric material has conducting dots applied to the conducting regions on a  first surface.   A second  sheet of  dielectric material  is  aligned  with  the  first  sheet  so  that conducting regions of a second surface of the second dielectric  sheet  can  be  coupled  to  the conducting dots.   The  structure  is  processed  so  that  the conducting dots cause the two dielectric sheets to be joined  both  physically  and  electrically  at  the conducting regions.   By  appropriate arrangement of the conducting regions, conducting traces on adjacent surfaces  of  adjoining   dielectric  sheets  and conducting  traces  on  opposite  surfaces  of  a dielectric   sheet  can  be  coupled  to  provide appropriate interconnection of electronic components.

Title: Process for joining molded silicon nitride parts
Inventor: GYARMATI ERNOE
IPC: C04B37/00
Filed: 1987-11-26
Granted: 1992-08-11
Abstract: ABSTRACT OF THE DISCLOSURE.         For joining shaped bodies of silicon nitride together, silicon nitride surfaces to be joined are first polished and then put into an apparatus for applying sputtered layers where they are first cleaned by ion bombardment in argon, followed immediately by sputtering with silicon in a nitrogen atmosphere such that a layer is deposited having a nitrogen content exceeding the Si3N4  stoichiometric ratio.  This readily provides a layer of the composition  Si3N5.5.    A   complementary nitrogen deficient layer is also provided in the joint before hot pressing,either in the form of a silicon layer that goes between the nitrogen-rich silicon nitride layers or in the form of a nitrogen-deficient silicon nitride layer sputtered onto a polished silicon nitride surface at relatively low nitrogen pressure.  The parts are isostatically hot pressed together at 1500 to 1750°C in a nitrogen atmosphere.   The layers which are usually thinner than 1 µm interact,with the disappearance of excess nitrogen and silicon, so that once the joint is produced all traces of jointure tend to  disappear.   The presence of a small amount of Y2O3  at the joint has a favorable effect.

Abstract: ABSTRACT        An infrared paper web moisture sensor is described which comprises a source of infrared radiation for directing an infrared beam through the web and an infrared detecting unit disposed on the opposite side of the web from the infrared source.  The infrared detecting unit measures the transmission of the infrared beam through the web at three separate wavelength regions of the infrared spectrum.  The transmission through the web in one wavelength region is primarily sensitive to the moisture content of the web, the transmission of infrared through the web in the second wavelength region is primarily sensitive to the basis weight of the web and the transmission of infrared wavelengths through the web in the third wavelength region of the spectrum provides an indication of the web temperature.  Signals are developed indicative of the transmission of infrared through the web in each of these regions, digitized, and fed to the process control computer for the paper mill.  The computer combines the values of the digitized signals, via an empirically derived equation, to produce a value indicative of the percentage of moisture in the web.  The process control computer utilizes this result to control devices which selectively add moisture to portions of the web or selectively dry portions of the web to thereby produce a web having a uniform moisture content.

Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus are provided for enhancing the transport of a selected ion having a predetermined charge-to-mass  ratio  through  a biomolecular membrane located in a space subjected to a local magnetic field.  The space defines at least one reference path passing through the membrane in opposite first and second directions.  The invention includes the steps of creating a magnetic field which, when combined with the local magnetic field, produces a magnetic field having a flux density with at least one component representable by a component vector having a direction extending in the  first direction along the path.  This component of the magnetic field has a magnitude that fluctuates at a predetermined rate to produce a nonzero average value.  A predetermined relationship between the ratio  of  the  selected  rate  to  the  nonzero  average  value  and  the charge-to-mass  ratio of  the  predetermined ion is  thereby created.   The predetermined  relationship,  is a  function  of  the  cyclotron  resonance frequency of the ion.

The microporous starch granules are chemically derivatized to enhance absorptive and structural properties. Absorbed functional substances are released from the microporous starch matrix under the influence of mechanical compression, by diffusion into a surrounding fluid or as a result of degradation of the granular starch matrix.
