Title: Method of coating fuel cell separator with seal material
Inventor: MACHIDA AKIYOSHI
IPC: H01M8/02
Filed: 2002-07-11
Abstract: A method of coating with a liquid seal material (61) the periphery of the ga s passageway and water passageway of a fuel cell separator (57), comprising th e steps of moving a nozzle section (33) installed in a seal material coating device (24) nearer to the separator than other portions than the coating sta rt portion, and moving the nozzle section at a lower horizontal movement speed than that of other portions than the coating start portion in a seal materia l coating start portion (63). Moving the nozzle section nearer to the separato r results in increasing the pressing force with which the seal material delivered from the nozzle section is pressed against the separator, to more intimately contact the seal material with the separator, thereby preventing the turning-up of the front end of the seal material. Further, lowering the horizontal movement speed of the nozzle section ensures coating with the sea l material to a more uniform thickness.

Abstract: Hop beta acids are improved with respect to their antibacterial properties, especially their anti-Listeria properties. Enhancement in this regard is especially useful for the treatment of food products which are susceptible to bacterial contamination. This can be especially important when the hop beta acids are to be used in surface application onto the food products. The hop beta acids are rendered more effective by combining them with a food grade acid, a potassium ion source, and an optional antioxidant in a carrier solvent such as, for example, a food grade alcohols or a food grade glycol. The improved hop beta acid compositions of this invention provide increase stability, higher hop beta acid concentrations, and/or higher anti-Listeria activities.

Title: Server process for accessing data from various types of client processes
Inventor: DELARUE GUILLAUME
IPC: G06F9/46
Filed: 2004-03-17
Abstract: A computer system allows client processes to access data through a server process. The server process contains an application and a motor. The motor receives requests in a first language from one of the client processes and issues responses in the first language to the client process. The motor communicates with the application in a second language distinct from the first language, the second language being an object-oriented language. In the second language, objects have properties and associated with events.  The application instantiates objects, evaluates properties of instantiated objects based on data and reacts to events. The motor issues responses in the first language to the client process according to the objects instantiated by the application and to their properties; the motor also provides updated properties and events to the application in the second language according to requests received in the first language from the client process. Thus, all client processes may access the data contemporaneously and share the data. Since the second language is distinct from the first language, the application may be used for various types of client processes, without being adapted.

IPC: B29C45/76
Filed: 2003-10-31
Abstract: The invention relates to a control device for controlling a machine, especially an injection moulding machine. Such control devices are problematic in the complexity thereof, the low degree of standardisation, the correspondingly high wiring costs and the resulting sources of error. The aim of the invention is to iron out said problems. To this end, the inventive control device for a machine comprises a bus board providing communication connections between different units, a wiring board, and a separate process-oriented module. Said module respectively comprises at least one process-oriented board providing a base area of input/output connections for the machines to be controlled. The process-oriented module can be directly connected to the bus board and the wiring board by means of a second or third type of plug, and thus produces a bridge, i.e. a connection, between the two boards, reducing the wiring required between the same. At least one control module which assumes the control tasks for the machine can be plugged into the bus board by means of a first type of plug-in contact.
