Title: Hand-held distance-measurement device with an enhanced viewfinding system
Inventor: HARRIS STEVEN E
IPC: G01S17/86
Filed: 1997-06-13
Abstract: The present invention relates to a portable, hand-held distance-measurement apparatus comprising a laser range finder which is aimed by an active viewfinder.  The active viewfinder improves the accuracy of the range finder by giving the user more visual feedback and thus allowing the user better control over the ranging operation. Under user command, the viewfinder enters a targeting mode wherein the user is presented with a illuminated targeting indicator inside the viewfinder.  The indicator is superimpose upon the field-of-view seen through the viewfinder.  In the targeting mode, the user aims the range finder by placing the targeting indicator on the object to be ranged.  Once the device is aimed, the user commands the distance-measurement device to execute a distance measurement cycle.  In one embodiment, targeting indicator flashes in various ways to indicate the quality of the data being obtained during the distance measurement cycle.  When enough data has been obtained to compute the distance, then the targeting indicator turns off, letting the user know that the display has been updated.

Title: Carbonylation of olefins
Inventor: BROWNING HORACE LAWRENCE JR
IPC: C07C53/126
Filed: 1995-12-15
Abstract: Disclosed is a process for the preparation of aliphatic carbonyl compounds selected from aliphatic carboxylic acids, alkyl esters of aliphatic carboxylic acids and anhydrides of aliphatic carboxylic acids by the carbonylation of olefins in the presence of a catalyst system comprising (1) a primary component selected from at least one Group 6 metal, i.e., chromium, molybdenum, and/or tungsten and (2) a secondary component selected from at least one of certain halides and tertiary and quaternary compounds of a Group 15 element, i.e., nitrogen, phosphorus and/or arsenic. The process is carried out in the absence of metals of groups 8, 9, and 10 (Fe, Rn, Os, Co, Rh, In, Ni, Pd, and Pt) and of formic acids and format esters. The process constitutes an improvement over known processes since it can be carried out at moderate carbonylation conditions without the necessity of using an expensive noble metal catalyst, volatile, toxic materials such as nickel tetracarbonyl, formic acid or a formate ester.

IPC: C12Q1/68
Filed: 1996-01-11
Abstract: L'invention concerne des procédés pour empêcher l'émergence d'une résistance multiple aux médicaments dans des cellules tumorales pendant une chimiothérapie contre le cancer. En particulier, elle concerne l'utilisation d'inhibiteurs de protéine kinases pour empêcher l'induction de l'expression du gène MDR1 ou gène de résistance multiple aux médicaments utilisés en chimiothérapie codant pour la P-glycoprotéine. On montre ici que l'expression du gène MDR1 qui provoque la résistance des cellules tumorales au traitement par chimiothérapie avec certains agents, est induite en réponse à un traitement par différents agents cytotoxiques, en particulier des agents qui sont ou qui ne sont pas sujets à une évacuation hors des cellules cancéreuses par l'effet de la P-glyocoprotéine. On montre ici que les inhibiteurs des protéines kinases, en particulier de la protéine kinase C suppriment ce comportement des cellules. En plus, on montre que ces inhibiteurs des protéines kinases inhibent l'expression d'un gène codant pour une protéine associée avec la résistance multiple aux médicaments (gène codant pour la protéine MRP). La présente invention concerne des procédés permettant d'utiliser de tels inhibiteurs des protéines kinases pour supprimer l'induction de l'expression du gène MDR1 par des médicaments cytotoxiques et, en même temps, pour inhiber l'expression du gène codant pour la protéine MRP. L'invention concerne également des procédés pour identifier des inhibiteurs des protéines kinases qui ont un effet sur l'expression du gène MDR1 et/ou du gène codant pour la protéine MRP. Ainsi, grâce à l'invention, on dispose de procédés et de composés utiles pour empêcher l'apparition d'une résistance multiple aux médicaments dans des cellules tumorales traitées par chimiothérapie avec des médicaments cytotoxiques chez des patients atteints de cancers, lorsque de tels inhibiteurs des protéines kinases sont administrés aux patients d'une manière concomitante avec le traitement par les médicaments cytotoxiques ou avant ce traitement.

Abstract: There is disclosed an automatic biochemical analyzer having a sample turntable and a reaction turntable. Plural sample containers for holding samples are arrayed on the sample turntable.          Plural reaction containers are arrayed on the reaction turntable.          A sampling pipette draws in a sample from some sampling container and injects the sample into some reaction container. A reagent pipette draws in some reagent from some reagent container and injects the reagent into the same reaction container. The resulting mixture is stirred by a stirring device. Produced reaction products are detected by a detector. Let N be the number of the reaction containers on the reaction turntable. The reaction turntable is rotated in M pitches in one step. Note that M and N do not have any common factor. First and second injecting positions adjacent to each other are established as positions where the reagent pipette can inject a reagent into the reaction container in position. First and second stirring positions adjacent to each other are established as positions where the stirring device can stir liquids in the reaction container in position. The stirring device can be moved between the first and second stirring positions.          Thus, one reagent pipette can be used for two kinds of reagents.          Also, one stirring device can be used for two kinds of reagents.

Title: Tapered screen assembly for a cellulose pulp digester
Inventor: JOHANSON JERRY R
IPC: D21C7/14
Filed: 1998-08-28
Abstract: A comminuted cellulosic fibrous material treatment vessel assembly includes a substantially vertical vessel having a top, bottom, and outlet, and through which the material flows in a flow direction. The vessel preferably has a substantially cylindrical wall with at least one diameter changing transition between the inlet and the outlet. A screen assembly is preferably provided at or just past the transition. The screen assembly comprises one or more annular screen surfaces diverging in the flow direction of the material, the angle of divergence being between about 0.5-10° to the vertical, and preferably substantially continuous.  Providing such a screen assembly reduces the radial compression of material thereon, and increases the volume and rate of liquid that can flow through the material and be removed through the screen surface compared to a non-diverging screen surface (that is a right-cylindrical surface). The screen surface has openings of substantially uniform size, and preferably with a substantially uniform percentage of open area, in the flow path.
