Patent CA-2064859-A1 (CA)
Inventor: BARAN JOZEF B
IPC: H05K1/14
Filed: 1990-08-22
Abstract: A multi-layer printed circuit board is constructed to suppress radio frequency interference (RFI) generated by high frequency clock and data signals therein. Suppression is achieved by positioning clock lines carrying the clock signal on a first voltage reference layer proximate to a second voltage reference layer. The two layers shield the clock signal from the signal lines on other layers. Noise may be further reduced by forming bridges in the second voltage reference layer proximate to the clock lines so that the bridges span the width of the clock line. Capacitors are also preferably utilized to further suppress radiated noise. The capacitors provide AC coupling between the first and second voltage reference layers so that a low impedance path is provided for high frequency noise generated by the clock signal. The second voltage reference layer thus operates as an effectively continuous shield between the bridges.

Title: Digital discriminator for pulse shaped pi/4 shifted differentially encoded quadrature phase shift keying
Inventor: CHENNAKESHU SANDEEP
IPC: H04L27/233
Filed: 1992-04-09
Abstract: RD-20,183 DIGITAL DISCRIMINATOR FOR PULSE SHAPED .pi./4 SHIFTED-DIFFERENTIALLY ENCODED QUADRATURE PHASE SHIFT KEYING     ABSTRACT         A digital radio receiver for synchronization of radiowave transmissions for digital and analog FM signals in TDMA systems such as cellular telephones uses a tangent type discriminator that minimizes the bit error rate.  The digital discriminator employs A/D converter circuit that samples a received intermediate frequency (IF) signal, a sorter circuit that produces a predetermined number of samples to be used in the decoding, a sample and phase adjustment circuit that allows for a carrier phase adjustment and sample timing adjustment, a divider circuit that eliminates the need for a conventional limiter by causing a ratio of amplitudes to be processed instead of absolute signal amplitudes, an inverse tangent circuit that creates a decoded phase angle from the ratio, a delay circuit and a summer circuit that create a differential signal, a modulo-2.pi. correction circuit that corrects for wrap-around errors about the real axis, an integrate and dump filter for summing up all phase angles pertaining to a single symbol, and a four-phase decoder circuit to decode the signal into a pair of bits.     An adjustment circuit minimizes phase error between a reference sequence of symbols and the decoded symbols by simultaneously adjusting the sample timing and carrier phase adjustments.  The digital discriminator also can decode conventional analog FM radio broadcasts by deactivating the IDF, the adjustment circuit, and SPA circuit, and bypassing the four-phase decoder.

Title: Sampling tool for obtaining samples of fluids present in a well
Inventor: BOE EINAR
IPC: E21B49/08
Filed: 1990-12-14
Abstract: A sampling tool for immersing into a well for collection of samples of oil, gas or water during drilling for production of said fluids. The sampling tool (1) comprises a tubular, hollow and preferably cylindrical member with two chambers (12, 14) separated by a compressible pipe (9). Said sampling tool comprises an outer pipe (2) formed as a cylindrical member to withstand the reservoir pressure. Inside the outer pipe (2) is positioned a unit (13) forming a gas tight storage chamber (12) for the gas-/liquid samples and a chamber (14) for a counter pressure medium. The chamber (14) is formed by pressing the pipe (9) against the inside of a U-profile (10). During sampling, the volume of chamber (12) will increase and the volume of chamber (14) will be reduced corresponding to the increase of chamber (12). Total separation of the gas-/liquid sample from the counter pressure medium is obtained by applying a diffusion tight flexible pipe (9) and the gas-/liquid sample analyzed will thus be representative for the reservoir gas-/liquid sampled.

Title: Apparatus and method for forming cable
Inventor: PASTA JOSEPH
IPC: G02B6/44
Filed: 1993-03-24
Abstract: A cable, which may be a fiber optic cable, includes a plurality of conductors which are twisted together. A tape with a layer of superabsorbent powder thereon, is wrapped around the conductors. A sheath is formed around the outside of the tape. If a leak should occur, the superabsorbent powder absorbs moisture and expands to block further entry of moisture into the cable. The tape is formed by applying a layer of adhesive to a strip of flexible material. The adhesive is advantageously applied in a helical pattern which is spaced from longitudinal edges of the tape. The superabsorbent powder is then applied to the adhesive. A suction head removes excess superabsorbent powder from the tape. The tape is then wrapped around the conductors of the cable. The adhesive may be a sealant material which is applied to the conductors before they are wrapped with the tape.
