Title: Method of and circuit arrangement for freeing communications resources, particularly for use by a switching element
Inventor: PFEIFFER BODO
IPC: G06F13/00
Filed: 1991-03-08
Abstract: Abstract Method of and Circuit Arrangement for Managing Like Units, and Switch Element Prior Art: A buffer in, e.g., an ATM switch element  re-ceives random data which is then called for by dif-ferent data sinks. After the data has been outputted to the data sinks, the memory locations of the buffer are released, i.e., labeled as free again.            Technical Problem: A memory location which is not marked as free as a result of an error (whether erroneously the data is not called for or whether the release procedure is erroneous) remains blocked a Basic Idea: All memory locations whose contents have been in the buffer so long that they definitely (or at least very likely) should have been called for are babeledas free.            Solution: Together with data, information on the time of entry is stored. All memory locations are checked at regular intervals for the age of their contents. Upon attainment of a predetermined age, the location is labeled as free.            (Fig. 13)

Filed: 1991-04-05
Abstract: A data reproduction circuit, for converting a read analog signal into digital data corresponding to recording data, has a second-order differential circuit for emitting a second-order differentiated signal of an analog signal read from a data recording medium,  an inverter for generating a comparative voltage that is switched between a plurality of levels, and a comparator for comparing the second-order differentiated signal and the comparative voltage to release digital data.   This permits cancelling a DC component of the read analog signal, and adopting a  2,7NRZI method for recording and reproduction, enabling a high recording density to be achieved.  The circuit further comprises a peak-detecting circuit for detecting and converting a peak of the read analog signal into digital data, and has a first-order differential circuit for emitting a first-order differentiated signal of the read analog signal, a three-state inverter for generating a second comparative voltage that is switched between a plurality of levels, and a comparator for comparing the first-order differentiated signal and the second comparative voltage to release digital data.  The circuit may thus be adopted for both RZ and NRZI methods.

Title: Apparatus for distributing clock pulses
Inventor: HERNDON WILLIAM H
IPC: H03K5/159
Filed: 1991-09-03
Abstract: APPARATUS FOR DISTRIBUTING CLOCK PULSES                 ABSTRACT OF THE DISCLOSURE A plurality of transmission lines communicate potentially skewed clock pulses from a source of clock pulses.  A combining transmission line is coupled to the plurality of transmission lines at a common node.  The impedance of the combining transmission line is chosen to be substantially equal to the parallel impedances of the plurality of transmission lines to prevent reflections which degrade the clock signal.  As a result, the combining transmission line combines the received clock pulses into a single clock pulse.  A plurality of distribution lines are thereafter coupled to the combining transmission line at a single node.  The parallel impedances of the plurality of distribution lines are chosen to be substantially equal to the impedance of the combining transmission line, once again to prevent reflections which would degrade the clock signal. The plurality of distribution lines then communicate the single clock pulses to their associated clock driven circuitry.
Patent CA-2055181-A1 (CA)
Title: Automatic flow control system and flood protector
Inventor: ENGLER CHRISTOPHER J
IPC: G01M3/28
Filed: 1991-11-08
Abstract: Abstract of the Disclosure An automatic fluid-flow control system is provided for controlling the quantity of fluid allowed to flow uninterrupted through a conduit.  It is particularly useful in controlling potentially damaging floods caused by breakage in a branch plumbing line used to supply water to beverage dispensing appliances, ice making machines and similar devices which repeatedly consume limited quantities of water in relatively short flow cycles.  The fluid-flow control system includes a flow meter which emits a signal containing information about the flow of fluid and also indicating when fluid is flowing and when it is not.  The preferred metering device emits pulses at a rate proportional to the flow rate.  A counter accumulates a pulse count during each period of fluid flow.  A separate pulse sensing network senses the beginning and end of each period of fluid flow and disables and initializes the counter whenever fluid is not flowing.  The accumulated pulse count in the counter is proportional to the quantity of fluid passing through the meter. The counter is set to close a solenoid valve whenever a predetermined maximum pulse count is exceeded.  A back-up protective circuit is also provided, employing a timer to measure the time interval of each fluid-flow cycle.  When the time interval is exceeded, the timer closes the solenoid valve.  In addition to the flood protector mode of operation, a configuration employing the same circuit as a dispenser control device is also disclosed.
