Abstract: There are described processes for the preparation of PNA oligomers of the formula see formula 1 in which B/X is as defined in the description, R0 is hydrogen, alkanoyl, alkoxycarbonyl, cycloalkanoyl, aroyl, heteroaroyl, or a group which favors intracellular uptake of the oligomer, A and Q are in each case an amino acid radical, k and 1 are in each case an integer from zero to 10, B is a natural nucleotide base or unnatural nucleotide base conventionally used in nucleotide chemistry or their prodrug forms, or else base substitute compounds, Q0 is hydroxyl or optionally substituted NH2 and n is an integer from 1 - 50. In these processes, the amino acid radicals and the units See formula 2 in which PG is an amino protective group which is labile to weak acids and B' is a nucleotide base protected on the exocyclic amino or hydroxyl function are coupled stepwise by the solid-phase method onto a polymeric support provided with an anchoring group and, after the construction has ended, the target compounds are cleaved off from the polymeric support by means of a cleaving reagent. There are furthermore described intermediates of the PNA oligomers and processes for their preparation.

Granted: 1999-08-03
Abstract: A passive/adaptive vibration control system is provided wherein various elements of the system may be adapted on-line in response to sensed vibrations. A spring/mass vibration absorber 67 is attached to a vibrating body 20 to absorb energy generated by that body, to minimize the transmission of vibrations to a structure 30 in mechanical communication with the vibrating body. In one embodiment of the present invention, the mass 60 of the vibration absorber may be adjusted, on-line, to compensate for sensed vibrations. A vibration sensor is connected to either the vibrating body or the attached structure so as to sense the level of vibration above a desired level and to send a signal representative of that vibration to an electronic controller. The electronic controller 500 is designed to instruct the actuator to adapt the mass to compensate for the sensed vibration. In additional embodiments of the system, the stiffness of the spring 65, rather than the mass of the weight, may be adjusted on-line to "tune" the vibration absorber. Further, if more than one excitation frequency is present, a plurality of on-line adaptive and/or purely passive vibration absorbers may be cascaded so as to minimize vibrations due to a plurality of excitation frequencies. Depending on the number of vibration axes to be attenuated, one or a plurality of passive/adaptive vibration absorber elements may be used.

Granted: 2005-09-20
Abstract: A radio access method for facilitating communication between at least one first station and a plurality of second stations is disclosed. First, each signal intended for transmission is buffered at a first station. The signals are then divided into equal length segments. The signal segments intended for a particular one of the second stations is transmitted using a corresponding time slot (Slot 1) in a regularly repeating time multiplex frame. The signal segments transmitted by the first station are received at at least one of the second stations and the signal segments are assembled from successive corresponding time slots (Slot 1) to reconstruct said intended signal. A transmit frequency channel uniquely associated with the corresponding receive time slot (Slot 1) is determined at the second station.      Finally, a signal intended for transmission to the first station is buffered in the second station and compressed for transmission using the transmit frequency channel during substantially the entire time period that the second station is not receiving.

Abstract: An automatic lubricator is microprocessor controlled and can be pro-grammed to deliver lubricant to a bearing or the like at selected intervals. A pressure for lubricant delivery in the range of 80 - 90 psi can be attained in less than a minute, but the bulk of the lubricant is kept under a minimal pres-sure of about 7 psi to avoid bleeding. Operation of the lubricator rests upon the use of a minor pressure imposed by a spring to force lubricant into the threads of an auger, so that rotation of the auger by a servo motor controlled by the microprocessor then dispenses the lubricant while at the same time providing a mixing action to the lubricant. Provision is also made for auto-matic shutting off of the lubricator at a preselected temperature.

Title: Servo-driven mud pulser
Inventor: FRITH TERRENCE G
IPC: E21B47/24
Filed: 1997-01-22
Granted: 2006-01-03
Abstract: An improved servo-driven pulser is disclosed, for use in measurement while drilling applications. In the pulser, a battery powered on-board DC electric motor is used to operate a servo-valve, which in turn adjusts internal tool fluid pressures to cause operation of a main valve to substantially reduce mud flow to a drill bit, thereby creating a positive pressure pulse detectable at the surface. De-energizing the motor driving the pilot valve results in re-adjustment of internal fluid pressures, causing the main valve to reopen, thereby terminating the pressure pulse.

Filed: 1997-07-22
Granted: 2002-01-15
Abstract: A knife projection sensing system for cutting machines having a rotatable surface adapted to retain a plurality of cutting knives.  The system employs a plurality of sensors mountable to the cutting machine to be stationary with respect to the rotatable surface. The sensors generate a signal capable of indicating the position of each cutting knife as the knives rotate past the sensors.  A microprocessor in communication with the sensors analyzes the signal generated to determine the projection of each knife from a reference surface and to determine if the projection of at least one of the plurality of cutting knives deviates outside preset desirable limits.  The projection status of the knives is communicated to an operator by a light display or paper printout.  The system can be used to ensure that knives are correctly installed in the cutting machine and to monitor knife position during normal operation.  The system can also be used to determine when knives need changing for sharpening.  If the projection of the knives exceeds preset limits, the system will automatically shut down the cutting machine to prevent damage.
