Patent CA-2237321-A1 (CA)
Title: A sleeve for orientating a tool
Inventor: MCLEOD GAVIN THOMAS
IPC: E21B23/00
Filed: 1996-10-25
Abstract: A sleeve (10) comprises a cylindrical member (12) provided at one end (14) with a pair of opposing tapered peaks (16) and (18). Peak (16) is higher (longer) than peak (18). Sleeve (10) is retained within a drive sub (26) of a ground drill and is constrained to move linearly along the drive sub (26). The peaks (16) and (18) cooperate with latch dogs (20) and (22) which are evenly spaced about and extend radially from a running tool (24). When the running tool (24) travels down the drive sub (26) and enters the sleeve (10), one of the latch dogs (20, 22) will strike one of the peaks (16) and (18) causing the tool (24) to rotate toward a predetermined rotational position. Because the peaks (16) and (18) are at different heights, latch dogs (20) and (22) cannot simultaneously contact the very top of each peak (16) and (18). If latch dog (20) strikes the top of peak (16), it will then slide down one of the sides of that peak causing the tool (24) to rotate. The other latch dog (22) will then contact an opposite or most distant side of the peak (18). This ensures that latch dogs (20) and (22) cannot slide down adjacent sides of the peaks which would cause the tool (24) to jam.

Title: Diaphragm actuated air cycle valve
Inventor: LUCAS CLIVE D
IPC: F16K31/165
Filed: 1997-02-12
Abstract: An actuated air valve includes a valve body (12) in line with a flow passage (14) for admitting a flow of fluid. A valve member (16) is pivotally mounted about the centerline of the valve body and is pivoted between high flow and low flow positions. A diaphragm (26) and linkage (20, 22) is in mechanical connection to the valve member. A pressure tap from the flow of fluid provides an impulse to the diaphragm which displaces the linkage, thus varying the position of the valve member. A three-way solenoid valve (34) is used to selectively admit the impulse to the diaphragm, thus governing the displacement of the linkage, and thereby varying the position of the valve member.

Abstract: A filtering unit for drawing liquid from a container by means of suction through a standard detachable straw. A standard drinking straw is attached to my filter over a protrusion on the filter surface. Suction applied from the protrusion through a straw, draws liquid through perforations on the bottom of the filter, then passing through the filter material which may be made of bone activated charcoal, carbon, fiberous material, or any other filtering agent, up through straw and into users mouth. Perforations, gauze, cotton, or anything capable of stopping filter material from entering straw and users mouth are placed at the base of protrusion and bottom of filter, thus encasing filter material in a conceiled compartment so as not to let filter material escape from shell and yet allow liquid to pass through when suction is applied.

Abstract: An high speed analog-to-digital converter, for converting an analog input signal (u(t)) with a maximum frequency (F max) to a digital output signal (x(n)) with an output sampling rate (F~) at least double the maximum frequency (F max), comprises a plurality of analog narrowband filters (Fo, F M-1) for filtering the analog input signal (u(t)) to produce a corresponding plurality of narrowband signals (X0-X M-1). Each narrowband filter has a passband. The sum of the gains of the narrowband filters at any frequency within an operating frequency band of the plurality of narrowband filters is substantially unity. Each of a corresponding plurality of analog-to-digital converter units (AD 0- AD M-1) comprises a sample-and-hold device (SH) and a quantizer (Q). The sample-and-hold devices are clocked by a corresponding plurality of clock signals (.PHI. 0-.PHI. M-1), respectively, each of the plurality of clock signals having a frequency at least double the bandwidth of the corresponding narrowband filter and an integer division of said predetermined sampling rate. The converter also comprises sampling and summing circuitry for sampling the outputs of the analog-to-digital converter units sequentially at the predetermined sampling rate (Fs) and summing the resulting sampled signals to produce the digital output signal (x(n)). The frequencies of the plurality of clock signals, and their phase-displacements relative to the output sampling clock signal, are such that each sample of the analog-to-digital converter output signal corresponds to a sampling edge of a different one of the sample-and-hold clock signal.

IPC: B60W30/18
Filed: 1998-12-18
Abstract: An integrated system for automatically controlling the operation of both an automated mechanical transmission and a multiple speed axle assembly in a vehicle drive train assembly includes a transmission actuator for operating the transmission in any one of a plurality of transmission gear ratios. The system further includes an axle actuator for operating the axle assembly in any one of a plurality of axle gear ratios. An electronic controller is provided for operating the transmission in a desired one of the plurality of transmission gear ratios and for operating the axle assembly in a desired one of the plurality of axle gear ratios to provide a desired overall gear ratio for the vehicle. To accomplish this, the electronic controller is responsive to one or more input signals that represent operating parameters of the vehicle. When it is determined that a change in the overall gear ratio of the vehicle is necessary, the electronic controller operates one or both of the transmission actuator and the axle actuator to achieve the desired overall gear ratio. The determination of whether the transmission actuator alone is actuated, the axle actuator alone is actuated, or both the transmission actuator and the axle actuator are actuated will depend upon the specific gear ratios provided by the transmission and the axle actuator, the current overall gear ratio, the desired overall gear ratio, and other factors.
