Title: Improved air flow apparatus for liquid ring vacuum pump
Inventor: WUNNER CHARLES HAMILTON
IPC: F04C19/00
Filed: 1998-11-10
Abstract: A liquid ring vacuum pump or compressor includes an off-centered housing and a rotor shaft assembly within the housing.  The liquid ring vacuum pump or compressor also includes a port-containing cone member having a frustoconical shape positioned in the rotor.  The rotor rotates liquid around the cone member forming an off-centered cylindrical liquid ring that is shaped by and centered in the off-centered housing.  The invented cone member has an inlet port having a parabolic shaped opening edge and a discharge port having a parabolic shaped closing edge.  The invented cone member fully supports the liquid ring, at the intersection of the inner surface of the cylindrical liquid ring and the outer surface of the wall of the frustoconical cone member and inhibits the flow of water into the ports, maximizes the amount of gas being displaced through the cone member, increases the capacity of the liquid ring vacuum pump, and reduces the cost of operating the pump.  A method of reducing water usage in a liquid ring vacuum pump is also disclosed.

Title: Postage metering system and method for a closed system network
Inventor: RYAN FREDERICK W
IPC: B41J29/38
Filed: 1998-12-17
Abstract: A postage metering system includes a plurality of meter printers operatively connected as part of a metering network and operating as client meter printers on the meter printer network. At least one postal security device (PSD) is coupled to at least one of the client meter printers (local clie nt meter printer). The PSD includes unique identification the ability to store postal value and generate digital signatures. The client meter printers function as a postage metering network wherein a client meter printer other than the local client meter printer (remote client meter printer) requests evidence of postage payment from the PSD for concluding a postage metering transaction. The local client meter printer functions as a meter server and the remote client meter printer functions as a meter client on the postage metering network. The remote client meter printer initiates a postage metering transaction in the PSD by sending a request for evidence of postage payment to the local client meter printer. The local client meter printer sends the request for the evidence of postage payment to the PSD, receives transaction information from the PSD and sends the evidence of payment to the remote client meter printer for subsequent printing.

Title: Printed decorations for pastry
Inventor: BRISSONNEAU GENEVIEVE SOCORRO
IPC: A21D13/08
Filed: 1997-06-23
Abstract: The present invention relates to a method of making edible decorations which reproduce all types of patterns, including colored patterns. The purpose of these decorations is partially or totally to cover the cakes for which they are intended and with which they form a perfectly homogeneous whole. More precisely, the invention consists in producing a printed decoration with five successive layers: a first layer of printed edible paper, and a second layer of a material for modifying the texture of the edible paper and sticking the first and third layers together. The third layer consists of a material belonging to the group comprising almond paste and chocolate. The fourth layer is equivalent to the second layer, and the fifth layer is equivalent to the first layer. By virtue of this innovation, a printed decoration does not detract from the cake and remains supple and homogeneous.

Abstract: L'invention concerne un procédé de transport selon lequel les récipients (1) maintenus de manière suspendue sont acheminés sous forme de flux de récipients dans une zone de réception (U.1) et dont le transport suspendu s'effectue sur une section de transport (FS) à orientation facultative dans l'espace, les récipients étant déchargés dans une zone de transfert (U.2). Pour assurer le transfert des récipients, des éléments de retenue (5) individuels successifs équidistants sont acheminés jusqu'à la zone de réception (U.1) depuis le haut le long d'une voie (7') courbe qui débouche à l'extrémité de la zone de réception de manière tangentielle dans la voie (8) des récipients acheminés. Chaque élément individuel (5) est introduit entre les récipients (1) dans le flux de récipients. Au début de la phase d'introduction, les éléments de retenue ont une vitesse (v') supérieure à la vitesse des récipients (v) et sont ralentis pendant la phase d'introduction dans le flux de récipients, pour parvenir à la vitesse desdits récipients. A cet effet, l'acheminement des récipients et celui des éléments de retenue sont synchronisés, de manière que chaque élément de retenue (5) ait atteint la vitesse des récipients (v) une fois être passé autour du précédent récipient, c.-à-d. qu'il ait été placé dans une position de retenue au moins potentielle par rapport à ce récipient. Par la suite, dans la zone de transfert (U.2), les éléments de retenue (5) sont tournés de 180· autour d'un axe vertical, de manière à pouvoir être déplacés vers le haut de façon analogue au mode de réception sur une voie courbe, afin de transférer les récipients sur un système d'évacuation (11). La voie courbe des éléments de retenue (5) dans la zone de réception (U.1) et/ou dans la zone de transfert (U.2) peut également être obtenue par pivotement individuel desdits éléments de retenue (5).

Patent CA-2262338-A1 (CA)
Title: Simulated fireplace assembly
Inventor: HESS KRISTOFFER
IPC: F24C7/00
Filed: 1999-02-19
Abstract: A device is provided for enhancing the realistic appearance of flames produced by a simulated fireplace (gas or electric) by providing additional ambient lighting effects in response to sensed light intensity within the fireplace. The device includes a photosensor, a control circuit, and display lighting. The photosensor senses the level of light intensity produced by a simulated flame source and changes its resistive value accordingly. The control circuit has circuit parameters which uses the resistive value of the photosensor to determine whether to apply operational power to the display lighting. The display lighting consists of at least one lamp positioned above the simulated fuel bed. When simulated fireplace is operational, the display lighting of the device produces a "flickering" effect that is synchronized with the changes in light intensity occurring within the fireplace. The resulting ambient lighting effect realistically mimics the changes in light intensity that normally occur above the flames of a real wood burning fireplace.

There is a resilient member with an opening therethrough that has an inner diameter substantially similar to the inside diameter of the hollow bore disposed in the cavity so that the opening is substantially axially aligned and in fluid communication with the open passageway. The hub of the epidural needle of the invention has a clamp with a releasable latch disposed about the resilient member. The clamp is selectively movable between an open position wherein the inner diameter of the resilient member is substantially unaffected. a clamp position wherein the clamp causes a strain to the resilient member and thereby reduces the inner diameter of the opening through the resilient member. The clamp also has a latch position where the latch releasably retains the clamp in the clamp position.

Inventor: CHARNEY ANNA
IPC: H04L12/54
Filed: 1998-03-27
Abstract: A flow control method and apparatus for controlling flow through an output link in a communication network modifies a Phantom flow control method by calculating a maximum allowable cell rate as a function of a number of active flows through the output link. To accomplish this, the method and apparatus calculates alpha smoothing parameters as a function of a number of virtual channels flowing through the output link. The method and apparatus improves the stability of the Phantom flow control method, and also enables it to be used with less costly network switches, such as shared memory switches. The flow control method and apparatus prevents a portion of the total bandwidth of the output link from being used when the maximum allowable cell rate through that output link is calculated.
