Title: Exhaust nozzle hinge
Inventor: NASH DUDLEY O
IPC: F02K1/80
Filed: 1990-07-12
Abstract: EXHAUST NOZZLE HINGE                   ABSTRACT OF THE DISCLOSURE    A hinge for pivotably connecting upstream and downstream wall sections of an exhaust nozzle of a gas turbine engine. Each wall section includes a liner spaced from the interior surface of the wall section to define respective first and second cooling air flow passages therebetween.  One of the wall sections includes a curved end portion and the hinge includes a leaf seal which extends from the other wall section and biases against the curved end portion to form an air tight seal and define, at least in part, a plenum at the hinged connection of the wall sections.  The plenum provides an air flow communication path between the first and second cooling air flow passages to transfer cooling air from the air flow passage of the upstream wall section to the air flow passage of the downstream wall section to thereby increase the efficiency of cooling of each of the wall sections.

Title: Method for reducing patient translation artifacts in tomographic imaging
Inventor: CRAWFORD CARL R
IPC: G06T11/00
Filed: 1990-07-19
Abstract: METHOD FOR REDUCING PATIENT TRANSLATION ARTIFACTS       IN TOMOGRAPHIC IMAGING     Abstract of the Disclosure A method of reducing artifacts in images acquired with fan beam, helical scanning, tomographic imaging systems, applies a weighting function to the tomographic projection set.  The weighting function reduces the contribution to the final image of projection data with large helical offset. Other redundant data within the projection set is increased in weight by the weighting function to prevent image artifacts from the weighting.  In one embodiment, the projection set is centered on the slice plane to avoid discontinuities in the projection data caused by the weighting functions.

Title: Process for manufacture of edible spreads and apparatus for the performance of said process
Inventor: HAVENSTEIN ALFRED G
IPC: A01J15/12
Filed: 1990-10-09
Abstract: L 7202 (R) ABSTRACT            Edible spreads are prone to microbiological spoilage by a number of organisms, including molds and bacteria as well as by physical changes occurring on storage.  While the growth of these organisms and consequently the onset of spoilage can be inhibited by the use of preservatives, some consumers find preservatives unacceptable.  We have determined that in edible fat products having a fine water drop spectrum and a fine crystalline fat phase can be produced without preservatives.  The invention provides an installation for the manufacture of such spreads a process for the production of such an edible spread which comprises the steps of; a) forming a coarse fat-continuous dispersion of water-in-oil, and optionally cooling said dispersion so as to obtain a fat continuous emulsion comprising from 0.5 to 2.5% solid fat, b) homogenising the product of step (a), and, c) working and cooling the product of step (b) to obtain an edible emulsion spread.

Patent CA-2036950-A1 (CA)
Inventor: JURISICH DRAGOSLAV
IPC: A61F5/44
Filed: 1991-02-22
Abstract: Abstract My invention is an improvement of all open end ostomy appliances used to collect feces or urine from bodies which eliminate food and water residues through a surgically created opening generally called stoma. My ostomy bag will not be open at the end, as all ostomy appliances are. Instead it will be open on the upper left or right side of it.  This improvement will eliminate one problem and greatly reduce another one. (a) It will eliminate the rubbing caused by the tail end closure--a variety of clasps usually made of plastic materials--which pinch, prick, and hurt the crotch and the tender parts of the body near it. (b) It will greatly reduce the risk of spillage, which occurs too frequently due to the pressure of the collected secretion on a clasp--any clasp used for closing an ostomy appliance.  When this happens, the contents of the bag are released into the user's underwear and down his or her legs, causing some very embarrassing and uncomfortable situations.           Those clasps also open frequently, even if the amount of the collectedrefuse in the appliance is rather small.  It may open when ostomates work in a crouching position, or during physical exercises, because a moveable part of the body--that is the upper parts of a leg--will often cause the clasp lose its grip.  Also a clasp may weaken before one would expect that to happen.  But if the opening of an appliance is in its upper part the spillage will be much lesser even if the clasp ceases to work. Moreover, the clasp will be located above the crotch, near a part of the body which is less active, and therefore less prone to cause the opening of the clasp.  But, more importantly, the pressure of the collected feces and urine on the clasp will be considerably smaller in those upper location.

Abstract: IMPROVED DATA DECOMPRESSION SYSTEM AND METHOD        ABSTRACT Data decompression of an image is implemented by reconstructing blocks of pixels from a table that stores orthogonal icons and related attributes representing a data compressed image. Each block of pixels is processed independently of all other blocks. Orthogonal processing is employed to reconstruct orthogonal features that relate to manufactured elements in an image. An optimum set of orthogonal icons and an optimum set of attributes for each icon are employed to further improve data decompression and fidelity. The optimal set of orthogonal icons includes a flat icon, an edge icon, a ribbon icon, a corner icon and a spot icon. The optimal set of at-tributes includes average intensities, intensity transition position and separation, and angle of the principal axis.

Abstract: Abstract of the Disclosure An  energy  spectrum  is  constructed  per  location from detected counts that are stored according to their measured energy as  well as  their  location.  Then  the  counts  per  location produced by unscattered photons is determined by  convolution  of  the  energy distribution  of  the  Compton  scattered  photons with the energy spread  function  of  the  system  to  provide  system   dependent Compton energy distribution/location.     A  trial  function of the system energy spread function multiplied by unknown coefficients of the unscattered  photons  plus  unknown coefficients  of  the  scattered  photons multiplied by the system dependent Compton energy distribution is constructed.     The trial function  is  locally  fitted  to  the  measured  energy spectrum  to  solve  the  unknown  coefficients of the unscattered photons. The now known the coefficients are  used  to  obtain  the count  of unscattered photons. The count of unscattered photons is used to produce Compton free images.
