IPC: H04B3/20
Filed: 1997-05-16
Abstract: A load coil device for a twisted pair telephone line is disclosed. The device is for compensating distributed stray capacitance in telephone lines that are longer the 18,000 feet. Typically, a load coil device would be inserted in the line every 6,000 feet. The device includes two windings, each winding to be connected in series with one of the conductors of the telephone line. The windings flatten the frequency response of the line in the voice frequency (VF) band. The device further has a capacitor connected in parallel across each winding. The values of the capacitors are chosen to provide a low impedance path that bypasses the windings for frequencies in the range of 20 kHz to 1.1 MHz. The device is particularly useful for long telephone lines over which high speed services such as asynchronous digital subscriber line (ADSL) are to be provided.

Patent CA-2254135-A1 (CA)
Title: Service control point congestion control method
Inventor: ATAI AMIR
IPC: H04M7/00
Filed: 1997-01-17
Abstract: In an advanced intelligent network, a method of using a Service Control Point (22) for managing the overloading of calls, for example, from calling parties in LATA A (20) associated with Service Switching Points SSP 1 - SSP n to a single telephone number (operators) in LATA Z (24) associated with SSP m (40).  The method enables Service Control Point (22) to service a small percentage of the time during measurement intervals in order to receive Termination Notification messages. The Service Control Point (22) then determines from the content of the Termination Notification messages for each measurement interval, the rate of attempted calls and the fraction of the total calls that were incomplete (i.e., erroneous or received a busy signal) for a telephone number n, and invokes Automatic Code Gapping for the number n where both the attempted call rate and the incomplete calls exceed a predetermined threshold.  If the threshold continues to be exceeded in subsequent measurement intervals, a larger gap interval for the Automatic Code Gapping can be set, and the process repeated until the proper gap is found.
Patent CA-2255836-A1 (CA)
Inventor: WATRINET HANNS
IPC: B32B37/22
Filed: 1997-05-21
Abstract: A laminating process for producing plastic cores with clad metal sheets have typically occurred in the roll gap and afforded a short laminating zone and only a small amount of heat introduced into the composite. A laminating mechanism of the present invention comprises three laminating rollers in an approximately L-shaped mutual arrangement that can be pivotably or tiltably arranged. The duration of the pressure is increased by the action of the subsequent loops wrapping around the rollers, in this way the laminated composite emerging from a first roll gap wraps partially round the roll and is passed through at least one further roll gap. This increases the compressive force and is suitable in particular when manufacturing technical grade laminates with high tensile strength outer layers of e.g. aluminium, steel or tear resistant woven materials.

Abstract: A digital logic simulation/emulation system (20), that includes a hardware pod (32) having configurable-logic ICs (36) arranged to provide a plurality of stimulus/response cells (72), is adapted for coupling to a digital logic circuit (316). The stimulus/response cells (72), which provide stimulus signals to the digital logic circuit (316), connect to form a shift-register for downloading stimulus-control data (252), and for uploading response data (262) during a stimulation-response cycle. A logic-configuration library (86) stores configuration-data for establishing a bit-slice architecture for the stimulus/response cells (72). To facilitate preparing the configuration-data, the system also includes a configurable-logic-specification process (224) having a GUI user interface. The logic-specification process (224) assigns pre-established, bit-slice configuration data for each stimulus/response cells (72) to specific locations throughout a configurable-logic IC (36) to achieve swift compilation of configuration data.

Title: Automatic toilet seat with protective covering
Inventor: SCHRECK ROMAN
IPC: A47K13/10
Filed: 1999-02-12
Abstract: An automatic toilet seat having two electric drives functioning independently of one another is provided. One motor is connected to the seat and the other operates a paper gripper. Both motors are controlled by appropriate sensors and by an intelligent microprocessor control device. This particular technological model has the advantage that, due to the separate arrangement with one drive motor for the pivot drive of the seat and, independent of that, one drive motor for seizing the protective cover, it is possible to operate both drives completely separately from one another and thus to link the drives by an intelligent microprocessor control.  With the intelligent microprocessor control unit, it is possible to adjust the two drives independently of one another and to adjust both of them to the site conditions (i.e., the location where the toilet seat is installed).

The Bi-212 is then eluted from the extraction medium with an acid solution to form a substantially radio-impurity-free Bi-212 acid solution. An apparatus for carrying out this process and a process for the therapeutic use thereof are also disclosed.
