Title: Material exchange column with a packing
Inventor: HUG ALBERT
IPC: B01J19/32
Filed: 1998-09-08
Granted: 2002-07-02
Abstract: The material exchange column (1) contain; a packing (2) which can be installed in the horizontal position of the column. The column has a ring gap (12) between the packing and the column wall (10) in which collars (3) are arranged. The latter each comprise a band shaped region (30) which lies in contact with the packing. At the upper edge of the band-shaped collar regions there adjoin spring-elastically connected surface pieces (31) which produce a bridge to the wall (10) and which are provided for a return conduction of the liquid from the wall to the packing during the operation of the column. It applies at least for some of the collars that the latter have elevations (4) in their band shaped regions which hold the ring gap open in a form-stable manner under the load of the packing when the column lies horizontally.

Filed: 1998-10-23
Granted: 2003-02-18
Abstract: A telephone call distribution system for determining destination for an incoming telephone call in a telephony network including a service control point (SCP) operates with a plurality of workstations each comprising a telephone coupled to the telephony network and a proximate computer station having a video display unit (PC/VDU), the PC/VD O connected to the SCP via a wide range area network (WAN), and a personal router associated with each PC/VDU. The SCP broadcasts  data pertaining to the incoming telephone call and a request for a destination to individual ones of the PC/VDUs via the WAN, a nd the personal roofers negotiate a destination based on individual routing rules and the data pertaining to the call. At least one o f the individual routers responds to the SCP with a destination for the call. In some instances the workstations are associated with a call center, and the call center may be CTI-enhanced. Individual routers in this instance may be exectued on a server on a local area network  connecting workstations at the call center, the server providing individual routers to workstations in a client-server relationship.

Abstract: A conveyor (52) for moving the strand from a sausage making machine (10) has J-hooks extending downwardly from a continuous chain conveyor (52). The conveyor (52) picks up the loops (28) of the strand at a loading station (16) immediately adjacent the discharge end (24) of the machine, and conveys the loops (28) to a processing station (14) for smoking or the like.      The conveyor (52) then moves the loops (28) to an unloading station (18) for removal of the strand from the conveyor, whereupon the conveyor(52) downstream of the unloading station (18) returns to the loading station (16) to pick up additional product. A conveyor take-up mechanism (20) is located immediately downstream from the loading station (16) to permit the conveyor to cease movement at the loading station (while the casing on the machine is being replenished) while the conveyor can continue movement in the processing area. Sensors and controls interconnect the machine and the conveyor (52) tocoordinate the operational functions of each. A method of producing and processing a strand of sausage of foodstuff involves producing a linked strand of material, depositing linked loops thereof on the hooks of a moving conveyor, controlling the coordinated activity of the production of the product with the movement of the conveyor; moving the product to and through a processing station, and thence to an unloading station, while periodically stopping the movement of the conveyor and the operation of the machine while continuing the movement of the conveyor through the processing area.

Abstract: Communicating commands and/or data to a remote controller, such as a programmable logic controller, coupled to a cellular communications device by sending multiple pages via a cellular network control channel of a cellular mobile radiotelephone system. Each cellular communications device operating within the coverage area of the cellular mobile radiotelephone system can monitor the cellular network control channel for a pair of target pages within a first time period. Each target page includes a specific identifier assigned to one or more of the cellular communications devices. In the event that a cellular communications device receives target pages having a matching specific identifier, the device will monitor the cellular network control channel over a second time period for at least one command page or data page carrying instructions or information for use by the remote controller. The cellular communications device can respond to the reception of one or more command or data pages by forwarding the instructions or information to the controller via a communications link. In addition, the cellular communications device can acknowledge receipt of the data or command pages by issuing an acknowledgment signal formatted as an Autonomous Registration signal via the cellular network control channel.

Abstract: A method and an apparatus for operating a satellite positioning system (SPS) receiver in a client/server architecture.      In one example of a method, a first plurality of pseudoranges is determined at a first time and a second plurality of pseudoranges is determined at a second time which is after the first time. The first and the second pluralities of pseudoranges are stored. After the second time, the first and the second pluralities of pseudoranges are transmitted to a location server, normally in one transmission. The location server then determines a first position from the first plurality of pseudoranges and a second position from the second plurality of pseudoranges.       In one particular example, the first and second pseudoranges are transmitted in response to a predetermined type of event, and the location server stores a collection of differential GPS data which has been collected over time.
