Abstract: A two piece hand brake release handle for a railway car hand brake mechanism having a relatively long lever one end of which is rotably fitted onto a rotatable brake release post extending from the hand brake mechanism, such that manual rotation thereof will not cause rotation of the brake release post, and a relatively short lever arm tightly fitted onto the brake release post such that rotation thereof will cause rotation of the brake release post, with the relatively short lever arm having an arm engaging flange extending transversely to receive and engage the relatively long lever arm such that manual rotation of the long lever arm in a given rotational direction will cause the long lever arm to engage flange so that continued rotational movement of the long lever arm in the same rotational direction will cause rotational movement of the short lever arm, and accordingly, rotational movement of the brake release post as necessary to effect a brake release.

Abstract: Ears, pods, or the like to be threshed are transported axially into an inclined threshing zone (16). Grain is liberated and falls through a sieve (24) forming a bottom of the threshing zone. Most of the lightweight material or chaff is carried to an exit (32) by means of a fan generated airflow stream. Grain and some chaff falling through the sieve (24) are collected in a trough (34) below the sieve. A fan generated auxiliary airflow stream (37) carries most of the remaining chaff to the exit (32). The larger portion of the grain slides down the trough (34) to exit at (36). The balance of the grain with virtually no entrained chaff exits the trough via an auxiliary grain exit (39). Transverse baffles (29 and 27), in tandem, opposing relationship, cause airflow to be circuitous to promote grain in preference to chaff to enter the exit (39). A final cleaning step may be performed in a cleaning apparatus (112).

Abstract: A metal diaphragm type valve includes a valve seat holder supported from a rotatable valve stem, a metal diaphragm and a deflection limiter.  The valve seat holder has a shaft extending upwardly through central openings in the diaphragm and the deflection limiter.  A diaphragm support step having an annular flat surface joining an arcuate shoulder is provided around the shaft of the valve seat holder and the inner peripheral edge of the diaphragm rests on the flat surface.  The deflection limiter has a flat bottom surface facing the top surface of the diaphragm and an arcuate surface extends radially outwardly from the flat bottom surface.  The deflection limiter, diaphragm and valve seat holder are welded together by a weld extending through the flat bottom portion of the deflection limiter and the inner peripheral edge of the diaphragm to the flat surface on the seat holder, the weld forming an air-tight seal between the valve chamber and the passage for the shaft.  The radial dimensions of the flat surfaces are different so that bending stresses occur in different regions of the diaphragm depending on whether the valve is opened or closed.

Title: Procede a gain non lineaire pour la prevention de l'emballement des regulateurs pid
Inventor: LAWRENCE RICHARD C
IPC: G05B13/02
Filed: 1998-08-17
Granted: 2006-01-24
Abstract: L'invention concerne un procédé de prévention de l'emballement d'un régulateur PID lorsque le paramètre de gain utilisé par ce régulateur PID de système de commande de processus est non linéaire. Ce régulateur PID est conçu pour fournir, dans un cycle d'exécution courant, une variable de commande (CV) à un dispositif de commande de processus en réaction à la définition d'une variable de processus (PV), d'un point de consigne (SP), et d'un paramètre de gain (K). La présente invention permet de recevoir la variable de processus, le point de consigne, et le paramètre de gain, puis de produire, pour l'écart de la variable de processus par rapport au point de consigne, une composante proportionnelle, une composante intégrale, et une composante dérivée. Les composantes ainsi produites servent ensuite à calculer, pour le cycle d'exécution courant, une variable de commande de sortie incrémentielle. Ensuite, à partir de la valeur de gain du cycle précédent, on calcule, pour le cycle d'exécution courant, une valeur de gain. On teste alors le paramètre de gain linéaire ou non linéaire, puis, à partir d'un paramètre de gain non linéaire, on calcule une composante de variation de gain non linéaire que l'on ajoute à la variable de commande de sortie incrémentielle. Le procédé consiste ensuite à produire, pour le cycle d'exécution courant, une variable de commande de sortie en ajoutant, à la valeur de la variable de commande du cycle d'exécution précédent, la variable de commande de sortie incrémentielle telle qu'elle a été modifiée par la composante de variation de gain non linéaire. La composante proportionnelle, la composante intégrale, et la composante dérivée produites par le cycle d'exécution courant servent à mettre à jour le cumul des trois composantes (proportionnelle, intégrale, et dérivée) des cycles d'exécution précédents. Ces cumuls serviront ensuite à calculer la composante de gain non linéaire du cycle suivant. Néanmoins, si le test fait apparaître un paramètre de gain non linéaire, on ne calcule pas la variation de gain non linéaire, et on obtient la variable de commande de sortie en ajoutant, à la valeur de la variable de commande du cycle d'exécution précédent, la variable de commande de sortie incrémentielle.

Abstract: Cette invention concerne la synthèse de tamis moléculaires composites à pores de grandes dimensions et les tamis moléculaires composites synthétiques à pores de grandes dimensions ainsi produits. Les tamis moléculaires de cette invention ont les mêmes fonctions d'utilisation générales que les tamis moléculaires comparables de l'art antérieur, ils sont cependant de meilleurs catalyseurs et de meilleurs absorbants. Cette invention concerne une synthèse hydrothermique de tamis moléculaires à pores de grandes dimensions produits à partir de nutriments, dont au moins un contient une structure d'ossature amorphe qui est elle-même principalement retenue dans le tamis moléculaire synthétique. Cette invention se fonde sur la découverte que les caractéristiques de porosité intrinsèque d'un nutriment qui possède une ossature oxyde à cation amorphe peuvent être sensiblement conservées dans le produit contenant le tamis moléculaire final formé au moyen d'un procédé hydrothermique et ce, au moyen de la régulation soigneuse des conditions dans lesquelles s'effectue le procédé hydrothermique. Par exemple, cette invention concerne la conservation d'une grosseur particulaire dans un produit contenant le tamis moléculaire final qui correspond à celle d'un nutriment à ossature oxyde à cation amorphe utilisé dans sa fabrication. Cette invention dirige la sélection des conditions du procédé pour obtenir une ou plusieurs caractéristiques de macroporosité et de mésoporosité ("porosité composite à pores de grandes dimensions") dans le produit tamis moléculaire final comme résultant directement de la réaction hydrothermique produisant le tamis moléculaire. Cette invention permet de produire un tamis moléculaire qui est incorporé in situ dans la morphologie de l'ossature d'une ossature oxyde à cation solide utilisée dans la fabrication du tamis moléculaire.
