Patent CA-2105632-A1 (CA)
Title: Commande de vitesse et de mode de fonctionnement pour melangeur ou appareil assimile
Inventor: PILAND CLINTON E
IPC: A47J43/08
Filed: 1993-09-07
Abstract: Cette invention consiste en un mélangeur muni d'un microprocesseur qui contrôle l'activation du moteur pas à pas du mélangeur, et de plusieurs boutons-poussoirs activés manuellement pour contrôler l'entraînement du microprocesseur à travers un programme qui détermine le mode et le tracé de l'activation du moteur pas à pas. Il y a N boutons-poussoirs de sélection de gammes de vitesses, M boutons-poussoirs de sélection de vitesse et un bouton-poussoir à impulsion. Selon l'ordre dans lequel ces boutons-poussoirs sont activés, le microprocesseur contrôle le moteur pas à pas dans un mode manuel continu à n'importe laquelle des vitesses N x M, dans un mode manuel à impulsion à n'importe laquelle des vitesses N x M ou dans un mode à impulsion automatique avec n'importe lequel des tracés d'activation. Dans le premier tracé, le moteur est activé pour fonctionner à des vitesses M constantes durant des intervalles T1 qui sont séparés par des intervalles T2 au cours desquels le moteur n'est pas activé. Dans un second tracé, le moteur part à une des vitesses M, l'activation étant diminuée graduellement sur chaque intervalle T1 de sorte que la vitesse du moteur diminue. Dans un troisième tracé, le moteur est initialement activé pour fonctionner à une des vitesses M et l'activation est augmentée à chaque intervalle T1. Tout mode peut être programmé pour un des intervalles de fonctionnement M. Tous les modes et tracés d'activation du moteur sont contrôlés par les boutons-poussoirs M + N + 1 (à l'exception des boutons-poussoirs MARCHE/ARR T) et l'ordre dans lequel les boutons-poussoirs sont activés.

Title: System controller and remote fault annunciator with cooperative storage, sharing, and presentation of fault data
Inventor: PATTON PAUL B
IPC: F23N5/24
Filed: 1993-06-02
Abstract: An annunciator for the conduction status of individual switches (15) wired into a series circuit records this status as status history at regular intervals in a memory (69). The status history is preferably recorded as individual entries having the identification number of an open switch (15) along with a time stamp specifying the length of time which that switch (15) has been open. The current entry is recorded in the mem-ory (69) and a new entry started each time the switch (15) for which an entry in the memory (69) is being created closes or a switch (15) currently receiving power opens. A controller (40) separate from the annunciator generates a request signal and provides a request time value to the annunciator specifying the time which has elapsed since the request condition was detected. The annunciator uses the request time value to de-termine the probable switch conduction status at the time of the request.

Title: Process for gas phase polymerization of olefin
Inventor: MORITA YOSHINORI
IPC: C08F2/34
Filed: 1994-07-12
Abstract: ABSTRACT      In the process for polymerizing an olefin in the gas phase according to the present invention, an olefin is continuously fed to undergo a gas phase polymerization in a fluid bed reactor in which a metallocene catalyst is present.  At least one compound selected from the group consisting of water, alcohols and ketones is added in a specified amount simultaneously with the feeding of the olefin.  Thus, an olefin polymer having a satisfactory drop second count index as defined by the below indicated formula is produced.                               wherein to and t respectively represent a flow time measured in the flow test according to ASTM D-1775 of the olefin polymer obtained when none of the water, alcohols and ketones is incorporated in the reactor, and that when at least one compound selected from the group consisting of water, alcohols and ketones is incorporated in the reactor.    The flowability of the polymer formed in the reactor according to the process of the present invention is excellent, so that blocking, bridging and the like do not occur during the gas phase polymerization.  Thus, it is feasible to stably produce a (co)polymer having excellent particle properties in high yield for a prolonged period of time.

Patent CA-2131663-A1 (CA)
Title: Gas turbine combustor
Inventor: SMITH KEVIN D
IPC: F02C7/18
Filed: 1994-09-08
Abstract: ABSTRACT OF THE DISCLOSURE The current invention concerns a combustor having a coupling for a cross-flame tube.  The coupling has inner and outer sleeves that form an annular passage therebetween. Holes in the outer sleeve place the annular passage in flow communication with cooling air  in the combustion system chamber, thereby causing the cooling air to flow over the proximal end of the outer sleeve.  A baffle is formed on the inner sleeve and has a pattern of raised and depressed areas. The raised areas form lands that are attached to the combustor wall.  The depressed areas form passages with the wall that direct the cooling air from the annular passage so that it flows over the surface of the combustor inner wall, thereby preventing over heating of the wall.

Title: Collapsible cage
Inventor: BRAUN HANS
IPC: A01K31/08
Filed: 1994-09-15
Abstract: Abstract of the Disclosure In order to permit a purchaser to assemble a collapsible case of the type described, simply and without the need for special tools, the side walls (2 to 5), which are usually four in number, are connected to each other by means of sectional corner connectors (7 to 10). The sectional corner connectors are longitudinally divided into two parts and consist of an outer part (16) and an inner part (17). Both parts are undetachably connected via rotating parts (22). In one variant, spreader springs (35, 36) ensure that the parts (16, 17) of the sectional corner connectors are held apart in the untightened state so that the widest possible gap (33) is created for inserting the edge zones (19, 20) of the gratings. When the rotating parts (22) are rotated, for example through about 90°, this causes the inner part (17) of the sectional corner connector to move towards the outer part, while at the same time clamping the edge zones (19, 20) of the gratings.
