Patent CA-2133286-A1 (CA)
Inventor: MOAKE GORDON
IPC: E21B47/08
Filed: 1994-09-29
Abstract: An apparatus and a method are provided for measuring the caliper of a borehole, and the standoff of a drilling tool from the walls of a borehole during a drilling operation. The apparatus includes three or more sensors, such as acoustic transducers arranged circumferentially around a downhole tool or drill collar. The transducers transmit ultrasonic signals to the borehole wall through the drilling fluid surrounding the drillstring and receive reflected signals back from the wall. Travel times for these signals are used to calculate standoff data for each transducer. The standoff measurements may be used to calculate the caliper of the borehole, the eccentricity of the tool in the borehole, and the angle of eccentricity with respect to the transducer position. The eccentricity and angle computations may be used to detect unusual movements of the drillstring in the borehole, such as sticking, banging, and whirling.

Title: Adjustable garment hanger
Inventor: BLANCHARD RUSSELL O
IPC: A47G25/48
Filed: 1994-12-01
Abstract: An improved plastic, clamp-style garment hanger is provided.   The hanger provides two clamps disposed on an I-beam-like crossbar on opposing sides of a hook.  The lateral positions of the clamp are adjustable.  The spring-clip that biases the garment engaging surfaces of the clamps together also provides frictional engagement between the clamps and the upper ridge of the crossbar.  Hooks disposed at either end of the crossbar are suitable for engaging straps and also limit the outward lateral position of the clamps.  Steps or stacking ribs disposed adjacent to the hook limit the inward lateral movement of the clamps.  The spring bias of the spring-clip against the clamps resists clamp creep under the weight of a heavy garment.
Patent CA-2139895-A1 (CA)
Title: Residual Echo Elimination with Proportionate Noise Injection
Inventor: GENTER ROLAND
IPC: H04B3/23
Filed: 1991-07-30
Abstract: Residual echo from an echo canceller circuit is reduced by a variable attenuator that operates in response to a processing circuit which determines and adjusts an attenuation factor.  The attenuation factor is determined by comparing relative levels of the send input signal, the receive input signal, and the error signal remaining after removal of an expected echo signal from the send input signal.  The variable attenuator provides linear power attenuation of the error signal in order to reduce transmission of the residual echo signal and to eliminate the perception of coupling and decoupling of the telephone connection which occurs in known echo cancellers employing center clipping.  A noise injection circuit provides a noise signal that is injected into the transmitted signal in inverse proportion to the attenuation of the error signal in order to provide a constant noise level in the transmitted signal as the error signal is variably attenuated.
