Title: Cellular mobile communication system
Inventor: FRISELL HOEGLIN ANITA
IPC: H04B7/26
Filed: 1995-08-17
Abstract: The present invention relates to a cellular mobile communication system comprising a number of radio base stations (BS) and a number of mobile stations (MS) wherein the system comprises a number of cells which are arranged in at least two different layers of preference.  Connections carried on the communications system can be handed over from one cell to another and at least one signal parameter is measured or monitored. At least one threshold is given at least for each cell in the lower layers or at least one signal parameter. The system furthermore comprises means for deciding on and controlling handover decisions comprising a priority ranking arrangement based on a number of criteria of which one is based on a comparison between a monitored value (I o) of a signal parameter with the threshold value (I o tr) of the serving cell and a second one is based on a comparison of the monitored value of a signal parameter (I i) with the corresponding threshold value (I i tr) for a neighbour cell wherein handovers are governed by the priority ranking arrangement so that a systematic passing also up as well as down between layers is obtained.

Title: Two component powder coating system and method for coating wood therewith
Inventor: DALY ANDREW T
IPC: B05D3/02
Filed: 1997-04-10
Abstract: Wood is electrostatically coated with a thermosetting powder coating system in which a mixture of a self-curing epoxy resin and a catalyst therefore is extruded and a low temperature curing agent are both pulverized and the powders are blended with conventional additives to make a coating powder which is deposited on a wooden substrate and heated to cure.  The mixture of resin and catalyst does not cure within the extruder but it is made to cure at low temperatures by the separate addition of the curing agent.  A small amount of the low temperature curing agent, insufficient to cause substantial curing during extrusion may be used in place of the catalyst.

Patent CA-2235262-A1 (CA)
Inventor: KLANFAR JOSEPH ROBERT
IPC: B29C45/32
Filed: 1998-04-21
Abstract: A centering arrangement for controlling relative movement between a series of mold support plates in a stack mold having three or more levels. The centering arrangement uses a plurality of centering devices which are substantially identical, each spanning two mold levels and being connected to three adjacent mold support plates. Each centering device has a shaft generally parallel to an axis of the mold and having an intermediate portion journalled in an intermediate connector to allow rotational movement about a shaft axis, but to restrain relative axial movement between the shaft and the intermediate connector. Helical splines extend from the intermediate portion toward opposite ends of the shaft in oppositely twisting helices. End connectors having cooperating splines engage the splined portions of the shaft and connect the centering device to the outermost of the mold plates to which it is connected. The intermediate connector secures the centering device to the intermediate of the three mold plates to which the centering device is connected. Relative axial movement between the end connectors and the adjacent intermediate connector requires simultaneous translation and rotation of the shaft in equal amounts in both end connectors, thereby maintaining the intermediate connector centered between the two adjacent end connectors.
