Abstract: A frame beaming reduction assembly for use with a motor vehicle to eliminate or reduce the amplitude of frame beaming oscillations in a vehicle's frame caused by vibratory forces exerted on a motor vehicle. The assembly includes a frame having a beaming frequency in a first range of frequencies, and an engine is attached to the frame wherein the engine generates engine vibration that has a second range of frequencies that is different than the first range of frequencies. A spring is positioned between a cross member of the frame and a forward engine mount of the engine. A damper formed by a pair of shock absorbers is positioned between the frame and a second forward engine mount substantially parallel to the spring such that the combination of the damper, the spring, and the engine has an offsetting frequency that is substantially equal to the frame's beaming frequency and that offsets the beaming frequency. The frame beaming reduction assembly effectively reduces the amplitude of the beaming frequency to approximately zero, whereby the frame beaming frequency oscillations are canceled and do not negatively impact the ride of the vehicle.

Abstract: A fusel oil is an alcohol or a mixture of alcohols having more than two, typically four or more, carbon atoms, whose presence in alcoholic solutions may be undesirable on account of its characteristic effect on taste and/or aroma. By reducing the temperature of alcoholic aqueous media containing fusel oil, the solubility of the fusel oil in the solution may be reduced, to the point where it no longer remains in solution. The fusel oil being lighter than aqueous alcohol, the medium separates into two phases, and the fusel oil phase may be removed. A better separation of fusel oil from the alcoholic aqueous phase is thus obtained than is possible through conventional dilution processes.

Granted: 2003-03-25
Abstract: A method of phase detecting a data input NRZ signal comprises applying the input data signal to a pair of parallel channels each comprising the same phase delay, and each clocked using the same clock signal. The phase delayed input data signal is coupled to respective inputs of a pair of phase comparators. The input data signal is coupled to a further channel comprising the same phase delay, and the further channel is clocked using the same clock signal. The phase delayed input signal is passed from the further channel through a further delay which is a fraction of that same phase delay, and the further delay is clocked using the clock signal. The further delayed input data signal is applied to another input of one of the phase comparators. The input data signal is applied through another phase delay which has the fraction of the aforenoted same phase delay (but is unclocked), to another input of the other of the phase comparators. Output signals are obtained from each of the phase comparators.

Abstract: An apparatus and method for orienting directional tools within a bore hole by recognizing and compensating for field biases brought about by ferromagnetic anamolies surrounding the bore hole, ferromagnetic casing strings and electrical/electronic tool components. The present invention includes the steps of measuring the magnetic field within a bore hole before casing strings are put in place and again measuring the magnetic field after such casings are in place. The ferromagnetic formation anamolies are detected in the first step of measuring the field prior to casing placement and further bias characteristics are determined in the second magnetic field measurement step after the casings are placed. Alternately, a conventional gyroscopic survey can be carried out to establish a bias in an already cased bore hole. Once a magnetic field bias has been established for the bore hole (for a particular casing string) this field bias is utilized to calculate and correct an azimuthal reading measured by electronic tools during placement within a particular casing. For a given location Y within the bore hole the field biases previously determined and resulting from formational anamolies and adjacent casings are factored into an azimuthal calculation in order to provide an accurate azimuth for tool orientation.

Abstract: Apparatus, and an associated method (110), selectively transmits packets of message data between a sending (12) and a receiving station (14). When a packet of message data (22) is received at a receiving station (14), the receiving station (14) acknowledges reception thereat of the packet with an acknowledgment response signal (42), transmitted back to the sending station (12). If the sending station (12) fails to detect an acknowledgment response signal (42), a packet of activity-request data (72) is sent to the receiving station (14). If the receiving station (14) fails to acknowledge reception of the packet of activity-request data, a determination is made that the receiving station would be unlikely to be able to receive an additional packet of message data (22). A channel to be used to transmit the packet of message data (22) can instead be reallocated for other purposes.
