Abstract: A rotary tool is disclosed, in particular a drill bit, comprising a shaft with cutting edges at the cutting end and with coolant ducts running through the shaft in an essentially longitudinal direction and opening out at the front ends. Two parallel ducts form the loop of a closed coolant circulation system by having sealing units fitted at the outflow ends at the tip of the bit; these sealing units allow a connection to be established between the outflows to create a coolant loop, while being fitted on the inside so as to be fluid-tight. This arrangement allows dry operation of the drill bit.

Title: Coning compensation in strapdown inertial navigation systems
Inventor: TAZARTES DANIEL A
IPC: G01C21/16
Filed: 1997-01-23
Abstract: The invention is a method for compensating for coning in a strapdown inertial navigation system which utilizes groups of five successive incremental angles of rotation of a body-fixed coordinate system as measured by orthogonally-mounted gyros at regular measurement intervals, each group of five measurements being obtained during a group interval equal to five measurement intervals. The coning-compensated angular displacement of the body-fixed coordinate system about a fixed axis in space during a p'th group interval is obtained by summing the five measured incremental angles and a coning compensation term. The coning compensation term consists of the sum of: (1) one-half the cross-product of a first and a second vector sum, the second vector sum being the sum of the five incremental angles of rotation in a group and the first vector sum being the sum of the second vector sum over p groups; and (2) the weighted sum of three vector cross-products, the multiplier and the multiplicand of each vector cross-product being a weighted sum of five measured incremental angles. The coning-compensated angular displacement can be summed over p to obtain an accurate estimate of the vector angle of rotation over a plurality of group intervals.

Title: Thermal mass flowmeter and mass flow controller, flowmetering system and method
Inventor: BUMP SCOTT S
IPC: G01F1/696
Filed: 1997-04-09
Abstract: A flowmeter (100) or mass flow controller (101) used in a manufacturing process with toxic and reactive process fluids. A fluid flow sensor (114) sensesfluid flow. A set point is established based upon predetermined temperature and pressure conditions at which the fluid will be utilized in the process. A valve drive (124) operates a fluid flow valve (126) to the resulting fluid flow rate, this being based upon the sensed flow rate and the set point. A control unit (122) controls the valve drive. The control unit accesses a calibration data set to determine the amount of fluid to be delivered by the fluid flow valve based uponthe sensed flow rate and the set point. This calibration data set is created for the controller over its operational range using a calibration fluid having similar thermodynamic transport properties to a process fluid. The instrument is calibrated using the calibration fluid and the data set is produced by converting the calibration data using process fluid data stored in a data base (200). Accessing the data set stored in the instrument together with routing signals over a communication network (300) permits the instrument to precisely control process fluids without having to introduce external correction factors or other adjustments to the process.

Title: Analog-to-digital converter and sensor device comprising such a converter
Inventor: JANSSON CHRISTER
IPC: H03M1/14
Filed: 1995-10-31
Abstract: The present invention relates to a periodically integrating analog-to-digital converter and a sensor device comprising such a converter. The analog-to-digital converter comprises a measured-value-to-pulse-amount converter, i.e. a sigma-delta converter of the first order that is reset to zero before each new period, and a digital counter for the number of feedback signals of known reference value in the measured-value-to-pulse-amount converter. This constitutes a rough measure of the input signal. It further comprises an analog-to-digital converter which converts the residual value of the measured-value-to-pulse-amount converter at the end of the period to a digital value, and an adder which adds this value to the output signal from the digital counter, resulting in a more accurate measure of the input signal.

Title: High-speed data transmission in mobile communication networks
Inventor: R S NEN JUHA
IPC: H04J3/00
Filed: 1995-12-08
Abstract: In a mobile communication system according to the invention two or more parallel traffic channels are allocated for high-speed data transmission over the radio path. Different channel numbers (ch0, ch1, ch2, ch3) are assigned to these parallel traffic channels for the duration of the connection. The data of a high-speed data signal is inserted at the distribution point of the transmission end (Tx) into frames each of which is provided with a channel number indicating the parallel traffic channel used for the transmission. The frames transmitted in a traffic channel always contain the same channel number during the whole call. The frames are divided into parallel traffic channel in the sequential order according to the channel numbering. At the reception end (Rx) the dta contained in the frames is reassembled into a high-speed data signal in the sequential order according to the channel numbers in the frames. Additionally, frame numbering may be used within each of the traffic channels so that at least two successive frames always have a different frame number (fr0, fr1). As a consequence, the allowed delay offset between the traffic channels will increase with the number of the frame numbers, and the order of the frames will be maintained under any circumstances.
