Title: Process of mechanical plating
Inventor: ROCHESTER THOMAS H
IPC: C09K23/00
Filed: 1996-09-16
Granted: 2000-12-05
Abstract: A method for adding pulverulent metal to mechanical plating processes occurring within an agitating container in which the parts to be plated are tumbled with an impact media and a pulverulent  coating  metal.    The  pulverulent  material  is introduced into the parts' container in a thick slurry capable of maintaining the  pulverulent metal  in  suspension.    The introduction of the metal into the plating container by the slurry produces a more uniform dispersion of the metal within the container than previous metal introducing practices.  The slurry, itself, may include additives other than thickeners to improve the coating process.

Abstract: A transmitter receiver implementing both frequency division duplex and time division duplex in one device in a CDMA mobile communication system. In the FDD mode, data in an interleave memory in an interleaver is read at a predetermined read rate VR = VN, where VN is a normal rate. In the TDD mode, a transmitting carrier frequency is set identical to a receiving carrier frequency, and the read rate VR of the interleave memory and the write rate VW of the deinterleave memory are set at VR = VW > 2VN. The transfer rate VT from column to column of the memories are set identical in the FDD mode and the TDD mode. This makes it possible to create a vacant duration while transferring from column to column, and to perform reception or transmission during the vacant duration. The remaining operation of the TDD mode is the same as the operation of the FDD mode.

Title: Difference gel electrophoresis using matched multiple dyes
Inventor: WAGGONER ALAN
IPC: G01N33/68
Filed: 1996-04-19
Granted: 2003-06-24
Abstract: A process and a kit are provided for detecting differences in two or more samples of protein. Protein extracts are prepared, for example, from each of a different group of cell samples (1, 2) to be compared. Each protein extract is labeled with a different one of a luminescent dye from a matched set of dyes.  The matched dyes have generally the same ionic and pH characteristics but emit light at different wavelengths to exhibit a different color uponluminescence detection. The labeled protein extracts are mixed together and electrophoresed together. The gel (4) is observed to detect proteins unique to one sample or present in a greater ratio in one sample than in the other. Those unique or excess proteins will fluoresce the color of one of the dyes used. Proteins common to each sample migrate together and fluoresce the same.

Abstract: L'invention porte sur un procédé ainsi que sur l'appareil correspondant permettant d'inventorier des échantillons congelés (25) de laboratoire utilisés dans un hôpital ou un centre de recherches. Ce procédé consiste à placer l'échantillon (25) dans un premier emplacement derrière la porte d'une cuve de congélation particulière (15), à sélectionner un "identificateur" (55) spécifique de cet échantillon (25) et à afficher un symbole représentatif de ce premier emplacement. Au fur et à mesure de la multiplication des échantillons, un classement correspondant à un emplacement secondaire, tertiaire et sous-tertiaire, etc.,  va s'afficher. Une étagère (19) peut constituer l'emplacement secondaire et une case (21) sur l'étagère (19) l'emplacement tertiaire. Le retrait de l'échantillon (25) du compartiment (17) suppose une manipulation du dispositif d'interface de la cuve de congélation, du clavier (43) et de l'écran (39) par exemple, afin de faire s'afficher le symbole du premier emplacement au moins. L'utilisateur  peut effectuer des manipulations en exécutant des "défilements" sur l'écran (39) ou en entrant certains paramètres d'identification de l'échantillon, notamment sa description et la date de son entrée dans le stock. Un dispositif optionnel de sécurité exige de la personne qui met en place ou retire l'échantillon qu'elle entre un numéro personnel d'identification (PIN).
