Title: Burner for operating an internal combustion engine, a combustion chamber of a gas turbine group or firing equipment
Inventor: KUHN EMIL
IPC: F23R3/12
Filed: 1992-06-17
Granted: 2002-10-15
Abstract: In a burner for operating an internal combustion engine, a combustion chamber of a gas turbine or firing equipment, which consists essentially of at least two hollow conical partial bodies (1, 2) positioned one upon the other in the flow direction, the ignition of the air/fuel mixture forming in the hollow conical space (14) takes place by means of ignition electrodes (24a, 24b, 25a, 25b) which are placed at a location where there is a low flow velocity of the combustion air (15). This achieves the effect that the flame tongues starting from the electrode ends (25a, 25b) of the ignition electrodes (24a, 24b) can feed a flame front (7) forming at the outlet from the burner continuously and along ordered paths, i.e. paths directed in the flow direction with slight swirl in consequence of the motion of the combustion air (15), so that a stable reverse flow zone (6) forms.

Title: Dimensional inspection process of medical ampules
Inventor: DASSLER HANS-ULRICH
IPC: G01B11/02
Filed: 1992-04-03
Granted: 1996-11-05
Abstract: To carry out an entirely automatic dimensional inspection process of medi-cal ampules, the ampules (1) are cyclically transported in the horizontal position on a chain conveyor (30) through an opto-electronic inspection station (10).  The ampules are lifted  from the chain  conveyor to be inspected and illuminated  bytransmitted light in a  direction normal to their longitudinal axis by a diffuse light-ing source (11).  In the case of  OPC-ampules, the ampule is retated around its lon-gitudinal axis during inspection.  The light that shines through the ampule is repro-duced on the opto-electronic converter (photodiode line) of a camera system  (12) which converts the reproductions into electric video signals.  These video signals are evaluated on the basis of the intensity variations caused by the inspected am-pule, in order to generate measurement values for the desired  ampule  dimensions as well as, if necessary, for deviations from the standard  ampule dimensions.

Title: Manufacturing method for producing sterile milk using dynamic microfiltration
Inventor: ALEX TONY
IPC: A23C9/142
Filed: 1993-03-25
Granted: 1998-05-05
Abstract: A method for treating raw milk to produce treated milk having a lower bacterial content than the raw milk. The milk is homogenized and within about 5 minutes from the homogenization, subjected to dynamic microfiltration, to yield a filtrate which has a lower bacterial content than the initial raw milk. When the flow rate of milk through the microfilter drops below a predetermined level, the dynamic microfilter is removed from milk filtration service, flushed with water, and returned to milk filtration service, the steps being repeated as necessary until the membrane cannot be rejuvenated to a minimum filtration capacity, at which time the membrane is subjected to chemical cleaning to essentially restore the original filtration capacity of the membrane.

Abstract: L'invention concerne un procédé de résolution des conflits lorsque des valeurs d'index de différents désignateurs binaires de bits sont déterminées comme étant égales. Ledit procédé peut être mis en oeuvre dans un système de transfert d'adresse d'une mémoire virtuelle à une mémoire réelle et, dans un autre mode de réalisation, dans un environnement de base de données. On utilise des désignateurs binaires de bits comprenant chacun un premier segment de comparaison, un deuxième segment d'index et un troisième segment de décalage. Lorsque deux index sont déterminés comme étant identiques, des groupes similaires de bits du premier segment sont considérés comme des index subsidiaires et sont utilisés dans la séquence jusqu'à ce que tous les bits desdits premiers segment ont été utilisés. Chaque fois qu'une opération d'indexage se produit, une nouvelle entrée de table dans une nouvelle table est identifiée jusqu'à ce qu'un groupe de bits des premiers segments des différents désignateurs binaires de bits soit déterminé comme étant inégal. Lorsque cela se produit, des comparaisons des entrées de table finale dans la table finale sont entreprises pour déterminer si chaque valeur mise en mémoire dans chaque entrée de table finale est égale à la valeur représentée par le premier segment associé.

La préforme permet une répartition homogène d'une petite quantité de poudre servant de matrice dans le cas d'articles hautement abrasifs très minces. Une couche poreuse peut être ajoutée au composite pour réaliser un article abrasif. Cette couche poreuse absorbe le liant liquide et elle soutient la poudre servant de matrice et les particules hautement abrasives, pour empêcher tout mouvement latéral et éventuellement augmenter la solidité de la préforme. Le composite final est chauffé ou fritté (de préférence sous pression) pour réaliser l'article abrasif, qui peut comporter un nombre quelconque de couches de particules hautement abrasives, de couches poreuses et de préformes.
