Patent CA-2106522-A1 (CA)
Inventor: SALECKER ROY W
IPC: B08B9/032
Filed: 1993-09-20
Abstract: A power unit for a conduit cleaner. The conduit cleaner has a motor with a housing carrying a shaft that is rotatable about an axis. The motor operates in response to the introduction of a pressurized fluid. The housing has inlets for admitting pressurized fluid and an outlet to permit the discharge thereof. A nozzle is connected to the housing and is configured to direct fluid from a pressurizedsupply to the housing inlet and direct fluid discharged from the outlet out of the power unit. The nozzle has a substantially cylindrical outer surface. In one form, the nozzle does not project beyond the cylindrical outer surface. Accordingly, acompact unit can be made according to the present invention. The absence of radially projecting structure also avoids protrusions that may intercept roots or other foreign matter within a conduit and thereby interrupt free movement of theconduit cleaner through a conduit.

Patent CA-2126872-A1 (CA)
Inventor: CARRALERO CESAR W
IPC: H03L1/02
Filed: 1993-01-27
Abstract: Certain operational characteristics of a crystal (104) are measured during a testing and grading process. Once determined, information representing these operational characteristics are stored in memory (120) and utilized by a controller (122) to increment a phase increment register (114) upon determining the crystals ambient temperature via a temperature sensing circuit (124). The value stored in the phase increment register (114) is then sent to a phase accumulator (116) where successive phase increments are summed together. This summed value is in turn sent to a sine lookup table (118) where the instantaneous phase value is converted into sine amplitude. Finally, a digital to analog converter (126) converts the amplitude bit stream into an analog signal for use as a reference oscillator frequency having extremely high frequency resolution. The above-mentioned process is repeated every clock cycle until a complete sine wave is produced at which point the phase accumulator is reset to zero and the process begins again.

IPC: H04N19/70
Filed: 1994-09-13
Abstract: For quantization of subframe feature vectors representative of subframes identified by subframe indexes in each frame of a time sequential signal, such as an audio or a video signal, a first feature vector of a first subframe of a current frame is extracted with additional extraction of a second feature vector of a second subframe of the current frame and is quantized by a frame vector quantizer unit into a quantized frame vector for the current frame.  Using a quantized frame vector for a previous frame and referring to interpolation coefficient vectors, an interpolator interpolates an interpolated feature vector for the current frame.  An error vector is calculated between the interpolated and the second feature vectors and is quantized by an error vector quantizer unit into a quantized error vector.  The subframe feature vectors are quantized by using the subframe indexes, the quantized frame vectors, the interpolated feature vector, and the quantized error vector.  Preferably, the interpolation coefficient vectors are adjusted according to a mode decided for the current frame by its subframes.

Title: Angiotensin iv peptides and receptor
Inventor: HARDING JOSEPH W
IPC: C07K5/103
Filed: 1993-06-24
Abstract: A unique and novel angioten-sin AT4 receptor and AIV ligand sys-tem for binding a small N-terminal hexapeptide fragment of Angiotensin II (referred to as AIV, with amino ac-id              sequence Val1-Tyr2-Ile3-His4-Pro5-Phe6) is disclosed. AIV ligand binds satu-rably, reversibly, specifically, and with high affinity to membrane AT4 receptors in a variety of tissues, in-cluding heart, lung, kidney, aorta, brain, liver, and uterus, from many animal species. The AT4 receptor is pharmacologically distinct from classic angiotensin receptors (AT1 or AT2). The system employs AIV or C-terminally truncated or ex-tended AIV-like peptides (e.g. VY-IHPFX) as the signaling agent, and the AT4 plasma membrane receptor as the detection mechanism. The an-giotensin AT4 receptor and receptor fragments (including the receptor binding site domain) are capable of binding a VYIHPF angiotensin AIV N-terminal peptide but not an angiotensin AII or AIII N-terminal peptide, i.e., DRVYIHPF or RVYIHPF, respectively. Also disclosed are processes for isolating angiotensin AT4 receptor and AIV angiotensinase, identifying angiotensin AIV agonists and antagonists, and constructing diagnostic assays to specifically measure AIV and AI-specific angiotensinase in biological fluids.

Title: Pump motor controller
Inventor: CHIPPERFIELD KEITH E
IPC: F04C15/00
Filed: 1995-01-10
Abstract: PUMP MOTOR CONTROLLER ABSTRACT OF THE DISCLOSURE A pump motor controller for making pump motor speed independent of fluid pressure at the inlet and outlet of the pump.  The pump motor controller senses motor speed and compares it with a reference input.  If motor speed differs from the reference input, a drive circuit receives a signal relative to the difference between motor speed and the reference input and increases or decreases the motor speed such that it converges to the reference input.  The drive circuit controls motor speed by using forward commutation to speed up the pump motor, and reverse commutation to brake the motor.  The motor controller also provides a frequency discriminator, operable to stop the motor by initiating reverse commutation when the reference input falls below a threshold value.
