Patent CA-2029248-A1 (CA)
IPC: H04L9/00
Filed: 1990-11-02
Abstract: ABSTRACT     A dual-framing-bit-alignment apparatus having a communications channel, a data device, an encryptor, a framing-bit device, a decryptor, a first framing-bit repositioner, and a second framing-bit repositioner.          The first data device generates a first data-bit sequence having a first framing-bit sequence.   The encryptor encrypts the first data-bit sequence as an encrypted-bit sequence.   The framing-bit device substitutes on the encrypted-bit sequence, a second framing-bit sequence,  thereby generating a framed-encrypted-bit sequence.   The decryptor decrypts the framed-encrypted-bit sequence as a second data-bit sequence.  The second data-bit sequence contains errors due to the second framing-bit sequence.   A second framing-bit repositioner detects in the second data-bit sequence, the first framing-bit sequence and the errors.          In response to detecting the errors and the first framing-bit sequence, the first framing-bit repositioner aligns the first framing-bit sequence with the second framing-bit sequence.

Inventor: MURPHY WILLIAM J
IPC: H01H71/74
Filed: 1991-01-15
Abstract: A microprocessor based circuit breaker has a removable rating plug which provides a reference for the current rating of the breaker. The removable rating plug also has an EEPROM to which the microcomputer of the circuit breaker writes for storage, the number of operations of the circuit breaker operating mechanism and a trip history of the breaker in the form of a count of the number of trips weighted by the magnitude of the trip current. The rating plug is periodically removed and plugged into a portable programmer which selectively displays the number of operations and operating history of the circuit breaker.      The programmer clears this operating data when recorded and can write into the EEPROM the style and serial number of the circuit breaker with which the rating plug is to be used.

The band (3', 4') of the hinge element can be stretched to an adapted tension through the intermediary of one of the hinge members (3a, 3b, 4a, 4b).
Patent CA-2080932-A1 (CA)
Title: Soliton generator
Inventor: KOROTKY STEVEN K
IPC: H04B10/18
Filed: 1992-10-20
Abstract: It has been determined that optical fibers possess a small amount of nonlinearity and, therefore, they are not exactly linear waveguides. This small amount of nonlinearity enables certain special pulse shapes to establish themselves and travel long distances without changing shape. These special pulse shapes arecalled solitons. This invention relates to a device for generating solitons by amplitude modulating an optical signal with separate in-phase electrical signals of different harmonically related frequencies. Specifically, an amplitude modulatorsuch as a Y junction Mach-Zehnder interferometer has multiple sets of distributed electrodes The interferometer has a set of electrodes for each electrical signal of a specific frequency. Thus, if three separate signals of harmonically related frequencies are used to amplitude modulate an optical signal, then the interferometer has three sets of electrodes located between the Y junctions of the Mach-Zehnderinterferometer. The structure of a separate set of electrodes for each of the signals results in a soliton generator which avoids the prior art problem of signal loss caused by combining many high frequency signals into a composite signal and the resulting need for a relatively expensive amplifier capable of uniformly amplifying the multi-octave composite signal.

Abstract: A process for preparing pillared chromium ribbon-like silicate clay .alpha.-olefin catalysts is disclosed.  This process utilizes palygorskite and sepiolite clays.  The pillaring of said clays comprise the steps of:  (a) preparing a hydrolyzed first solution by dissolving a chromium salt and a base in water, heating said first solution to a temperature in the range of about 20°C to about 100°C while stirring continuously until the solution reaches a pH in the range of about 1.5 to about 2.5 and thereby producing a master batch; (b) diluting said master batch with water to produce a diluted second solution and heating said diluted second solution to produce a heated second solution; (c) adding a solid clay selected from the group consisting of sepiolites and palygorskites to said heated second solution, and continuing heating; (d) recovering said pillared chain silicate clay; (e) drying said pillared chain silicate clay to form first product.  The activation of said clays comprise the steps of:  (a) heating said first product at a temperature in the range of about 150°C to about 500°C and for a time period in the range of about 30 minutes to about 10 hours in an inert atmosphere; (b) thereafter reheating said first product at a temperature in the range of about 500°C to about 900°C and for a time period in the range of about 1 hour to about 50 hours in an oxidizing atmosphere and recovering said catalyst composition.  This results in clay catalysts which polymerize .alpha.-olefins.
