Abstract: A process control method that automatically and comprehensively manages the creation, storage and use of electronic records during the operation of a controlled process and for governing and documenting the users that operate the computer systems that are involved in the creation, storage and use of the electronic records. The method controls a process, such as a chemical process, by receiving measurement information relating to the process, applying rules to the received measurement information to determine a desired response, and sending control information to at least one device associated with the process, so as to modify the process. The method maintains the rules, measurements and control activity in transaction logs or audit trails related thereto in a secure database.

Abstract: One aspect of the invention relates to a method for line matching of analog communication lines in telecommunications networks, whereby signal processor(s) and/or programmable digital filters are used. Coefficients of the line transmission function are calculated by an echo compensator to be compared with pre-specified filter coefficients in a filter device assigned to the line, in which case, an incorrect line matching is identified and a new set of filter coefficients is generated, which is fed into the filter device. In this case, the first values to be accepted and processed for the coefficients of the line transmission function calculated by the echo compensator and used for comparison, are those that are determined by an echo compensator for a first line gateway in a line path, which is associated with the reflection with the shortest delay time. In networks with high dispersion of the line parameters, the invention re-establishes the task distribution between line matching and echo compensator.

Abstract: In real-time communication between a communication terminal device of a first packet-oriented communication network and a second packet-oriented communication network, data packets which are to be transmitted are transmitted from the communication terminal device in essentially uncompressed form via the first communication network to a data compression device, in order to be compressed before being forwarded into the second communication network.

Abstract: A cleaning system for cleaning a plurality of service tanks located at different sites spaced widely apart from each other. A set of storage tanks is located at one site, for storing cleaning solutions, each cleaning solution being recirculated through a respective recirculating line from each storage tank. The cleaning system further includes cleaning stations, one for each service tank assembly, each located close to its respective service tank assembly, each cleaning station having a connection to each recirculating line. Each cleaning station includes a wash/motive tank for a washing liquid, a rinse tank for a rinsing liquid, and an outlet line leading from each of the wash/motive tank and the rinse tank. Liquid is conveyed from the outlet lines of the wash/motive tank and rinse tank to the respective service tank assembly via a feed line. A return line is adapted to return liquid from the respective service tank assembly. An eductor has a vacuum opening connected to the return line.

Abstract: A secondary communications device, such as a modem, a facsimile machine, an automatic meter reader or an answering machine, shares a telephone line with a subscriber's telephone and must grant the telephone primary access to the line. The present invention prevents the secondary device from seizing the line when the telephone is already off-hook and will terminate a line seizure by the secondary device if the subscriber picks up the telephone handset during use of the line by the secondary device. An average interval for charging a capacitor to a threshold voltage in response to an on-hook voltage appearing across the telephone line is determined. When the secondary communications device is ready to use the line, circuitry measures an interval for charging the capacitor in response to the current voltage appearing across the telephone line. The secondary communication device seizes the line only if the measured interval does not exceed the average interval by more than a predetermined amount.

Abstract: A fluid flow control assembly for controlling the flow of fluids to and from a number of tanks, and for controlling the communication of that flow. Raw material, product, CIP solution and drain conduits pass near to the tanks. The fluid flow control assembly which is the subject of this invention includes three sets of valves. One set of valves regulates the flow of raw materials from the first conduit into the tanks. Another set of valves regulates the flow of product out of the tanks into the second conduit. A third set of valves regulates the flow of CIP solution out of the tanks into the third conduit. Each set of valves prevents flow of fluid into or out of its respective conduit when desired, such that one of the tanks can be being filled at the same time another of the tanks is being emptied of product and a third one of the tanks is being flushed with CIP solution.

Abstract: An input keyboard (1) contains a switching device (3) for pushbuttons (22) wherein the contact linings (11.1, 11.2) on a printed circuit board (10) are bridged by a countercontact (16) operated by the pushbutton (22). The countercontact (16) consists of a carbonized plastic foil (14) and an electrically conducting layer (17) on the side facing away from the contact linings. By virtue of this arrangement there comes into being a bridging resistance between the bridged conductor strips (12.1, 12.2) that depends on the operating pressure (P) applied to the pushbutton, this resistance being then used to cause a control circuit arrangement (6) to generate a control command (Bf) for setting a particular function and an adjustment command (Bw) for setting a particular value or adjustment rate.

Abstract: A remote control transmitter includes a function selector device (17) for outputting selection signals in dependence on a function selected by operating the device. A function is selected by tilting the function selector device which includes optically functioning tilt switches. For this purpose, a ball guide housing (50) is constructed with five ball resting places, i.e. places in which a ball (K) within each specified tilt range always adopts a stable position. At one of the ball resting places a light transmitter (D) is mounted, while at other ball resting places light receivers (P1-P3) are located. A multi-bit signal is outputted by the light receivers, with the different bit sequences corresponding to different selection signals.

Abstract: In a method for the insertion of balancing weights in pockets of an insulating end disc of an electrical machine rotor, only balancing weights of the same weight value are utilized. The balancing weights are distributed over the weight-receiving pockets on both sides of a plane extending through a determined balancing position and the axis of rotation of the rotor. The inserted balancing weights are secured in their respective pockets by means of respective detent closures.

Abstract: Film processor having a lighttight chamber defined in part by a door, a station at which a processing kit containing therein a rupturable container of processing liquid may be located, a rack movable from a first position toward a second position during which it opens the kit and also latches the door in a closed position, and a manually operable lever for moving the rack between said positions. Movement of the lever toward a processing position is transmitted to the rack and to a processing container rupturing member so as to cause the rack to open the processing kit prior to movement of the rupturing member into rupturable engagement with the container as the rack moves into the second position. Also, during such movement of the rack, the door is latched in the closed position, thus preserving the lighttightness of the chamber during processing of a length of film.
