Filed: 1991-06-27
Abstract: ABSTRACT OF THE DISCLOSURE     The chair of the present invention includes a power-assisted linear actuation drive mechanism having a modified nut or "cam guide" which is linearly moveable upon rotation of the power screw for selectively actuating the lift and tilt linkage mechanism for causing forward lifting and tilting movement of the chair when the motor is operated in a first direction.  Rotation of the screw shaft in a second opposite direction acts to lower the chair to the normal seating position.  Continued rotation in the second direction causes sequential operative extension of the leg rest assembly followed by angular reclining movement of the chair.  This sequential operation of the leg rest assembly and the reclining linkage are independent and may be easily disabled to selectively eliminate either of the features.

Title: Method for controlling fines production in unconsolidated and loosely consolidated formations
Inventor: JENNINGS ALFRED R JR
IPC: E21B43/02
Filed: 1991-08-14
Abstract: ABSTRACT         A method for controlling fines production in an unconsolidated or loosely consolidated formation penetrated by a cased hole.  The cased hole is perforated in a manner sufficient to treat a formation interval with a consolidation resin.  A thermally stable consolidation resin is injected into the interval and allowed to set.  This resin is then drilled out of the hole.  Afterwards the casing is reperforated and hydraulically fractured with a fluid containing a fine grain refractory proppant.  A resultant fracture is propped by said proppant which removes fines from hydrocarbonaceous fluids produced after initiating a thermal enhanced oil recovery operation in the formation.

Inventor: STUHLER WILLIAM B
IPC: B62M9/08
Filed: 1991-08-19
Abstract: A fully automatic torque converter transmission is presented that uses a "V" belt with inner teeth that engage mating teeth on a variable pitch pulley core in a low speed high torque state transformable into an infinitely variable higher speed shift mechanism. The bicycle pedal sprocket drives a pivoted cluster of three small sprockets with a drive chain loop interconnect driving a first sprocket as a driven member, and the other two serving as idlers in maintaining the chain at constant length. A speed ratio of approximately 1:6 from the pedal sprocket to the driven sprocket optimizes torque transmission capacity of the system with the driven sprocket attached to a self-centering, spring loaded, variable pitch pulley. This pulley has a core shaped like a timing belt pulley with grooves (or teeth) at its surface. The "V" belt driven by the variable pitch pulley drives a timing belt type pulley that rotates on a center fixed relative to the bicycle frame, and is a "Y" belt with teeth on its inner surface enabling engagement with the variable pitch pulley core at the low speed high torque position. This converts the friction "V" belt drive to a positive drive in low gear.      The driven pulley, finally, drives the rear wheel through a conventional bicycle chain.

Abstract: Il existe une famille de métalloprotéinases clivant des molécules matricielles extracellulaires. Ces métalloprotéinases sont secrétées sous une forme inactive latente et nécessitent une activation afin de cliver spécifiquement le substrat préféré. On a préparé une série de peptides, basée sur l'analyse de la séquence complète de procollagénase de type IV. On a synthétisé des inhibiteurs des peptides correspondant à des régions de répétition de cystéine et à des régions contenant de l'histidine; le mécanisme d'action de ces peptides met en oeuvre l'inhibition de la liaison de l'enzyme au substrat. On a synthétisé des inhibiteurs des peptides correspondant au peptide clivé lors de l'activation, et constituant une nouvelle classe d'inhibiteurs de métalloprotéinase. Ces inhibiteurs sont des éléments d'une série de peptides contenant la séquence d'acides aminés RKPRC constituant le noyau, ou des analogues de ceux-ci. Le reste de cystéine est requis pour permettre l'activité. On peut utiliser des anticorps purifiés par affinité développés contre des peptides spécifiques pour a) détecter toute enzyme de métalloprotéinase générale à l'aide de la séquence dans la partie VAAHE ou PRCGNPD, et la distinguer des autres éléments connus de la famille de métalloprotéinase, b) bloquer des domaines fonctionnels ayant pour effet l'inhibition de l'activité enzymatique, et c) distinguer les formes latentes des formes activées de l'enzyme.
