Abstract: The  present  invention  provides  a  method  for alternately feeding  reactive  gas  and  inert  gas  into  a chamber,   and  is  preferably  used  in  a  semiconductor manufacturing plant to form films on wafers.  The inert and reactive  gas  feed  lines  have  shunt valves  connected as branches to the primary sides of the line changeover valves, with a vent line being connected to the outlet sides of the shunt valves.  The opening and closing operation of the line changeover valves and the shunt valves alternately feeds reactive gas and inert gas into the chamber, the lines being changed  over  after  a  specified  time  interval.     The simultaneous evacuation and exhaustion of the vent line by a vacuum pump suppresses pressure fluctuations in the chamber during changeover of the gas feed lines.

Title: Nondigestible fat compositions containing solid polyglycereol ester particles for passive oil loss control
Inventor: HOWIE JOHN KEENEY
IPC: A23L19/18
Filed: 1993-10-21
Granted: 1999-01-19
Abstract: Nondigestible fat compositions useful as a replacement for triglyceride fats or oils in foods are disclosed. The compositions have relatively flat Solid Fat Content (SFC) profile slopes between typical room and body temperatures. The nondigestible fat compositions comprise a liquid nondigestible oil and nondigestible solid polyglycerol ester particles dispersed in the oil in an amount sufficient to control passive oil loss. The ester groups of the solid polyglycerol ester particles comprise long chain (C16-C24) fatty acid radicals, with at least about 40 % of the long chain fatty acid radicals being saturated and having at least 18 carbon atoms. Edible fat-containing products containing these nondigestible fat compositions can be less waxy tasting due to the lower level of solids required for passive oil loss control.

Abstract: Shock absorbing fork, especially a front fork, for a two-wheeled vehicle, particularly a bicycle, of the type having a pair of telescoping struts and a hydraulically damped shock absorbing arrangement disposed within each of the telescoping struts, the shock absorbing arrangement having a piston which divides a hydraulic fluid containing cylinder into upper and lower chambers, a valve regulating flow of hydraulic fluid through the piston between the upper and lower chambers, and a piston rod connected to the piston. Among the improvements of the invention is the provision of a spring for absorbing shocks that acts on the piston of the hydraulic shock damping arrangement upon compression of the telescopic struts, and a location sensitive flow control arrangement having a flow path extending between opposite sides of said piston and a flow adjusting element which is displaceable into and out of said flow path as a function of the extent which the spring is compressed by compression of the telescopic struts. As a result, flow through the flow path is progressively changed as the struts are compressed and the damping characteristics of the hydraulic damping arrangement are progressively varied. Furthermore, a compression damping adjuster shaft having an axially adjustable abutment member thereon to hold the resilient pad against a spring disc of the compression valve of the piston under a holding pressure which is adjustable by axial displacement of the abutment member. Additionally, the entire hydraulically damped shock absorbing arrangement is formed as a self-contained replaceable cartridge unit.

Abstract: La dimérisation et l'oligomérisation de protéines sont des mécanismes généraux de commandes biologiques contribuant à l'activation de nombreux processus cellulaires. Nous avons mis au point un procédé général de dimérisation ou d'oligomérisation régulée (inductible) de protéines intracellulaires. Comme l'illustre la figure 15, on peut provoquer l'association de l'une ou l'autre de deux protéines cibles en traitant les cellules ou les organismes qui les contiennent avec des ligands synthétiques perméables aux cellules. En résumé, nous avons provoqué: (1) l'aggrégation intracellulaire de la queue cytoplasmique de la chaîne aux états du complexe récepteur (TCR)-CD3 de cellules T, ce qui conduit à la signalisation et à la transcription d'un gène reporteur, (2) l'homodimérisation de la queue cytoplasmique du récepteur de FaS, ce qui implique une apoptose spécifique à la cellule (mort cellulaire programmée) et (3) l'hétérodimérisation d'un domaine de liaison de l'ADN (Gal4) et d'un domaine de transcription-activation (VP16), ce qui provoque la transcription directe d'un gène reporteur.
