A titanium-based carbonitride cutting tool insert with superior thermal shock resistance is disclosed. This is accomplished by sintering the material under conditions where the melting process is reversed. The melt forms in the center of the material first and the melting front propagates outwards towards the surface. This leads to minimal porosity and a macroscopic cobalt depletion towards the su...

A CT apparatus (10) employing a cone beam of x-rays (14) reduces image artifacts by employing full as opposed to half scans of less than 360 DEG . The present invention recognizes that rays of a cone beam (14) that cross the imaging plane are not redundant with opposing rays in the scan, as is the case with the rays within the imaging plane. In a second embodiment, half scans of less than 360 DEG ...

In the formation of a tread pattern having many sipes (30), a combination of pitch segments (15, 16, 17) having a plurality of kinds of pitch lengths (L1,L2,L3) is selected so as to substantially match with the tread circumference (T) and an inner peripheral length (L) of a sector member (36) constituting part of a split mold (35) in order to prevent intersect of the sipes with any dividing positi...

Rechargeable Pb-acid battery has an upper battery casing (10), lower battery casing (20), and an intermediate support extender (40). The bottom casing includes a number of support pins (29), integral with the casing. The extender has holes (43) passing through for flow of electrolyte and includes sockets (45) to fit over the pins (29). Pins (47) on the extruder fit in sockets (15) on the underside...

A method for determining the direction of a borehole during drilling comprises determination of inclination angle theta and highside angle phi from gravity acceleration ( &upbar& g) measurements and determination of azimuth angle psi from magnetic field ( &upbar& B) measurements along with the calculated inclination angle theta and highside angle phi , the determinations being carried out...

The process involves a pair of electrodes, brought up to the working area, which provide a generated impact as the current flows through the path of least resistance. The current path is modified by a second generator enabling the loosened material to fall away. The impact generator unit (1) supplies the electrodes (2), at a rock face (6), with an alternating current which flows through the path (...

An arrangement for the non-stop changing of stacks in the curved arm of a printing machine, comprises a stack carrier which can be pushed in the advancing direction between two separate sections, and a separating unit which supports the upper section until the carrier (4) reaches its insertion position. A holding unit (3) prevents the upper section from moving due to the carrier. The separating un...

The system passes the exhaust gases of a gas-turbine (41) to a heat exchanger or exhaust gas flue (9) via a flue gas channel (1) and downstream slider (valve) arrangement, which consists of at least one flue gas flap (2) whose rotation axis (3) is essentially perpendicular to the base of the system. The heat generator is a waste heat steam generator. The exhaust gas flue is mounted on the base of ...

This unit cleans the filter, which is mounted in a casing (25) carrying the nozzle (29) used in injection or spraying of thermoplastic. The casing includes the housing (14) holding the filter. The rear of the nozzle is held against the filter assembly (20) in the operational position. This ensures that the fluid plastic mass flows through openings from the filter sections. To clean the filter arra...

For the conditioning of yarn wound into cops, at a ring spinner or twister, after the yarn is wound round the sleeve an additional fluid is applied to the wound yarn according to a set program, before the sound cops are transferred to a conditioning appts. Also claimed is a winding sleeve with openings for fluid to pass through. Pref. during conditioning, the wound yarn at the start is heated to a...

A resistive exercise suit has a resistive shirt (10) and resistive exercise trousers (12). The resistive exercise shirt (10) uses tension bands (44, 46, 48, 50) on sleeve fronts and backs and attachment to central elastic blocks (40, 42) on the front and back of the shirt. Both the tension bands and the elastic blocks are incorporated into the shirt and provide means by which resistance can be mad...
