Patent CA-2181596-A1 (CA)
Inventor: WOLF MICHAEL
IPC: H04L25/05
Filed: 1996-07-18
Abstract: When digitized signals are transmitted from a digital transmission system (NET1), e.g. a PDH system, to another digital transmission system (NET2), e.g. a SDH system, which operate at different clock rates (f1, f2), the clock rate must be adapted during the transition. To that end, the digitized signals are converted into discrete-time and value-discrete signals in a decoding unit (D1) at the clock rate (f1) of the one digital transmission system (NET1). A conversion unit (UE1) converts the discrete-time and value-discrete signals into further discrete-time and value-discrete signals, whose pulse repetition rate is adapted to a clock rate derived from the clock rate (f2) of the other digital transmission system (NET2). This is achieved e.g. with a low-pass filter (FIL1) and a sample-and-hold device (AH1). An encoding unit (K1) converts the further discrete-time and value-discrete signals into digital signals, whose bit rate is adapted to the clock rate (f2) of the other digital transmission system (NET2), which allows the digital signals to be transmitted in the other digital transmission system (NET2).

Title: Combination aquatic fin
Inventor: CIRJAK DAVID
IPC: B63H16/04
Filed: 1996-08-16
Abstract: A set of fins for aquatic use provides improved propulsion, lift, and stability.  The fins are worn radially, typically on either the arm or the leg.  Each fin is characterized by a stiff forward portion and a flexible rearward portion.  The combination of the stiff and flexible portions produces a fin that propels the user with either a paddle or a flipper motion.  The fins' stiff portions also can be oriented to resist lateral movement, lending stability to the user.  Each fin is shaped as a hydrofoil and can be oriented to create lift forces to encourage the user's body to float higher in the water.  Notches in the hydrofoil reduce turbulence and restore laminar flow.

Abstract: A method and apparatus for resolving Doppler frequency shift ambiguities in pulse Doppler radar systems provides a radiated signal (11) that is modulated with a periodic waveform (13) having a plurality of pulses within a period, the interpulse intervals between pulses in the period being unequal. Radar target returns are autocorrelated (31) for a plurality of lags, which may include the interpulse intervals and linear combinations thereof. The calculated (33) arguments .theta.Ci of the autocorrelation function are unwrapped (35) by adding 2k.pi., k = 0, ~1, ~2, ..., to the phase .theta.C1 obtained for the shortest lag T1 and determining an integer mk2 from |(.theta.C2 + 2mk2.pi.) - (T2/T1) .theta.C1| < .pi. and then setting .theta.2 = .theta.C2 + 2mk2.pi.. Phase angles .theta.3, .theta.4, ..., .theta.m are unwrapped in a similar manner, the integer mki being determined from |(.theta.Ci + 2mki.pi. - (Ti/Ti-1) .theta.Ci| < .pi.. The unwrapped phase angles and the point (0,0) are least mean square fitted (37) to lines of phase angle vs lag for each value of k. The root mean square error (39) of the phase angle offset from each line is determined and the slope of the line with the minimum RMS error is chosen as the Doppler frequency shift from which the velocity of the target is extracted.

Inventor: PAPLINSKI WALTER
IPC: E21B43/38
Filed: 1997-02-06
Abstract: A method for downhole separation of natural gas from brine with injection of spent brine into a disposal formation. Firstly,  select a free flowing gas well having a suitable disposal formation.  Secondly, separate the gas well into a disposal zone, a production zone and a separation zone.  The disposal zone has a pressure sensitive valve set to open within a preset threshold pressure range.  The separation zone is in fluid communication with the pressure sensitive valve. Thirdly, position a gas/water separator in the separation zone.  Fluids flowing up a production conduit pass through the gas/water separator thereby separating the gas from the brine.  The spent brine accumulates in the separation zone with the pressure sensitive valve intermittently opening to inject spent brine into the disposal zone when the weight of the accumulated column of spent brine reaches the threshold pressure range.

Title: Apparatus for forming sheets of material having a uniform thickness and cutting individual portions therefrom
Inventor: OUELLETTE EDWARD L
IPC: A21C3/10
Filed: 1995-08-09
Abstract: An apparatus for forming a sheet of material, e.g., dough or masa, from a supply of the material includes a pair of rotatable rollers that define therebetween a gap into which is input a dough mass and out of which is produced a dough sheet. Fluctuations in the size of the roller gap are sensed by detecting changes in the position of one of the rollers, which changes are input to a servo system that automatically corrects the position of the one roller so as to maintain the proper gap size. The one roller is movably mounted in scissor-like fashion and is easily driven by a servo motor. A  cutter is provided which presses against one of the rollers to cut individual dough portions from the sheet. The ends of the cutter are subjected to a bending moment which induces a camber in the cutter. This prevents the central portion of the cutter from bowing away from the roller and ensures uniform pressure between the cutter and roller, even for applications with an extremely long cutter and rollers.
