Title: Method of simultaneously microwave heating or baking plural articles, and concomitant package
Inventor: MCCUTCHAN MICHAEL D
IPC: B65D81/34
Filed: 1990-10-23
Granted: 1995-01-17
Abstract: A METHOD OF SIMULTANEOUSLY MICROWAVE HEATING OR BAKING        PLURAL ARTICLES, AND CONCOMITANT PACKAGE     ABSTRACT A method of simultaneously microwave heating or baking a plurality of articles  such  as  comestible  articles:   for  example, brownies,  cupcakes,  muffins  or  cookies  or  the  like.  The  method comprises  the  steps  of arranging the  plurality of articles  in  a predetermined,  vacant-center  array  within  an  ovenable  container, non-sealingly enclosing the array of articles in the container so that the articles  share a common headspace in the container,  and applying microwave energy for a sufficient period of time to effect the heating or baking.  In a preferred embodiment, the predetermined plurality is  eight,  and the array is  a three-by-three orthogonal pattern  with  a  vacant  center  position  or zone.   The method  may further comprise preparing a bakeable batter, subdividing the batter into a plurality of equal  portions with one portion in each of a plurality of like receptacles so that, upon being baked, each of the portions becomes one of the articles.  A package is also provided to facilitate practicing the method.  A preferred package comprises a mix for preparing a bakeable batter, a plurality of receptacles into which the batter may be subdivided, and a container or enclosure such as a carton which is sized and configured to accommodate an array of articles  or  batter  laden  receptacles,  and  to  provide  a  common headspace  above  the  articles.    The  package  may  also  comprise selectively  patterned  and/or  positioned  microwave  susceptors  or reflective materials to further ensure uniform heating or baking of the  articles.   A  package embodiment  of  the  invention  is  also disclosed in which plural articles are arranged, when packaged, in a predetermined, open-center array.

Title: Proximity detecting apparatus
Inventor: GEISZLER THEODORE D
IPC: H04B5/00
Filed: 1990-07-18
Granted: 1995-11-07
Abstract: A  proximity  detection  system  which  combines  the advantages of an electrostatic  (electric)  field coupling mechanism with those of an electromagnetic coupling mechanism in order to overcome the disadvantages of the respective individual coupling mechanisms.  The system includes a coded tag which is excited with an induction field, i.e., by using an electromagnetic coupling mechanism as has been done in the past in such proximity identification systems,  but which transmits stored data back to the receiver using both an electric field coupling mechanism and an electromagnetic field coupling mechanism.  The receiver, in turn, is provided with a novel preamplifier circuit arrangement,  so that it can simultaneously receive signals via either or both of these coupling mechanisms.

Title: Process for the preparation of alkaline earth metal alcoholates having a spherical particle habitus
Inventor: STANDKE BURKHART
IPC: C07C29/68
Filed: 1991-12-13
Granted: 2000-08-08
Abstract: Alkaline earth metal alcoholates having a spherical particle habitus are prepared by dissolving an alkaline earth metal alcoholate in a solvent, adding a second solvent which dissolves the alkaline earth metal alcoholates only with difficulty, or does not dissolve them, but which is homogeneously miscible with the solution of the alkaline earth metal alcoholate in the first solvent, then by removing the first solvent and separating the precipitated alcoholate. The particle size can be controlled by means of the shear gradient during the precipitation or by the use of emulsion stabilisers. The emulsion stabilisation leads to particles in the size range 0.5 to 20 µm with a particularly narrow particle size distribution. The alkaline earth metal alcoholates particles so prepared, in particular magnesium alcoholates particles, are useful as an active catalyst support material in polyolefin synthesis. Since particle morphology and size distribution of particles prepared by the process of the invention are superior compared with the prior art, this has a favourable effect on the properties of the produced polymer powder, such as a narrower particle size distribution and a smoother surface structure.

Title: Method and apparatus for construction of flooring to prevent squeaks
Inventor: CORSTON CHARLES
IPC: B65C5/02
Filed: 1992-03-20
Granted: 2000-03-07
Abstract: A method of constructing a floor so as to prevent squeaking due to movement of the floor decking relative to the joists. The joists are installed, and strips of resiliently compressible cushioning tape are laid on the upper edges of the joists so that an adhesive side of the tape adheres thereto to keep the strip in position, and so that a non-adhesive side of the tape faces upwardly therefrom. Floor decking is placed on top of this so that the strip of tape is sandwiched between the decking and the joists, and the non-adhesive surface of the tape permits the decking to be slid thereover to a desired position. Fasteners are than driven through the decking and into the joist to secure the decking in position, and the resilient cushioning tape fills any gaps between the joists and the decking so as to prevent the decking from moving on the joists and causing squeaks. A tool for laying the strips of tape is made up of a spool mounted on a handle so that the tape unwinds from the spool and adheres to the joist as the tool is moved in a forward direction.

Title: Elimination of heterojunction band discontinuities
Inventor: SCHUBERT ERDMANN FREDERICK
IPC: H01L33/10
Filed: 1992-08-18
Granted: 1996-04-30
Abstract: Conduction band or valence band discontinuities occurring at the junction of two unipolar heterogeneous semiconductors can be eliminated by compositional grading of the heterointerface and appropriate doping of the interfacial region. The compositional potential of a graded junction and an interface dipole potential generated by modulation doping of the interfacial region are selected such that they exactly compensate each other. The compositional grading of the interface is achieved by semiparabolic grading of narrow regions immediately adjacent each side of the interface. The modulation doping is achieved by dopingthe two materials with suitable dopants, donors for the conductance band or acceptors for the valence band, depending on the polarity of the structure. Thisreduces the resistance in periodic semiconductor multilayer structures leading to low-resistance distributed Bragg reflectors.

Title: Computer method and system for allocating and freeing memory
Inventor: MORSE PETER L
IPC: G06F12/02
Filed: 1993-07-26
Granted: 1996-12-31
Abstract: A method and system for allocating and freeing memory is pro-vided. In a preferred embodiment, a requesting program running on a computer system allocates a logically contiguous block of memory (a "heap") for the temporary storage of data structures. A Heap Manag-er, provided by the present invention, manages the heap in response to requests from the requesting program. The Heap Manager allocates and frees blocks within the heap. The Heap Manager logically divides the heap into segments and maintains a free list for each segment. The free list is a list of the free blocks contained in a segment. The heap has an associated free block array and an associated size tree. The free block array has a plurality of entries; each entry points to a free list for a segment. Each leaf node of the size tree corresponds to a plurali-ty of entries in the free block array. A value contained in each leaf node indicates the size of the largest free block in the segments corre-sponding to the plurality of entries. The size tree is arranged in such a way that the value of each node is equal to the largest value of its child nodes. The Heap Manager selects a free block for allocation to the re-questing program by searching the size tree and the free block array and selecting a segment that contains a free block that will satisfy the request, and then searching the free list corresponding to the selected segment to locate the smallest free block that satisfies the request. The Heap Manager frees a block in a segment by updating the free list for the segment, the free block array entry that points to the free list, and the size tree.
