Abstract: PCT No. PCT/JP81/00357 Sec. 371 Date Jul. 2, 1982 Sec. 102(e) Date Jul. 2, 1982 PCT Filed Nov. 27, 1981 PCT Pub. No. WO82/01839 PCT Pub. Date Jun. 10, 1982.A welding method comprises rotating a nozzle (3) provided with a welding electrode (9) eccentrically from the center axial line (a) thereof within a groove (2). The center axial line (a) of the nozzle is aligned with the center of the groove (2) by smoothing values of variation in welding current or welding voltage for each of the left and right half cycles of the nozzle and controllably moving the nozzle horizontally at right angles to the welding direction so that the difference between these values becomes null. The height of the nozzle (3) relative to the groove (2) is maintained at a prescribed distance by smoothing values of variation in welding current or welding voltage and controllably moving vertically the nozzle (3) so that the difference between the thus smoothed value and a set value becomes null.

Abstract: An arrangement for generating a wet compression of gas, which is compressed in a multi-stage radial gas compressor (10), which has an impeller (14), a guide apparatus (17) "downstream" of the impeller and a transverse duct (18) connected to the downstream end of the guide apparatus, contains a number of liquid nozzles (24, 30) for injecting an evaporable liquid, such as for example water, into a gas flow which is compressed. The liquid nozzles (24, 30) are arranged axially symmetrically about the longitudinal axis of the compressor shaft (15) and in such a manner that they inject the liquid into the guide apparatus (17) essentially upstream of the transverse duct (18), and have a radial spacing from the axis which amounts to approximately 1.05 to 1.1 times the maximum radius of the compressor impeller (14, 22). A considerable increase in the evaporation of the injected liquid is achieved, which results in a better compressor capacity and lower wear of internal compressor parts. <IMAGE>

Abstract: A press section of a paper machine comprises, in the direction of web run, at least three separate press nips for removing water from a web, the web passing between two fabrics in each of the three nips. Dewatering of the web takes place through both faces of the web at least in the first press nip which is formed between two open-faced press rolls. The second and third press nips are formed between an open-faced roll and one of an open-faced roll and a smooth-faced roll. According to the invention, the press section includes two upper fabrics and two lower fabrics, the first upper and lower fabrics in the direction of web run being water-receiving press fabrics, one of which constitutes a press fabric only in the first press nip, the other fabric constituting a press fabric both in the first and second press nips. One of the second upper and lower fabrics is a water-receiving press fabric, the other being a water-non-receiving transfer fabric adapted to receive minimal amounts of water, if any. The web is transferred on the transfer fabric after the third press nip as a closed draw into the drying section which follows the press section.

Abstract: In a hydrostatic radial piston motor, the conventional mechanical control of the supply and exhaust of working fluid to the cylinders is replaced by electromagnetic changeover valves which are actuated, in dependence upon the position of the motor shaft 2, by a microprocessor 22. An angle detector 20 cooperating with a toothed ring 19 secured to the motor shaft 2 detects the position thereof. This arrangement allows the energization and de-energization of the valves 14 to be programmed as required in dependence upon the angle of motor shaft rotation. This programmable feature enables the motor to have any required acceleration curve and deceleration curve. <IMAGE>

Abstract: These measuring systems are, for example, those in anaesthetic and therapeutic breathing apparatus and monitors, in which the measurement values can be output continuously or intermittently. It is the aim and object to compensate for a false signal produced by parameter effects, which causes a zero-point deviation. This is essentially achieved by means of an inverting and a non-inverting circuit arm which is connected or disconnected by means of an electronic switch or makes it possible to store a difference voltage (zero-point deviation) in order to utilise it for the correction.

Abstract: Existing methods of transmitting torque to the shank of a cutting tool give rise to noise and wear esp. under shock loads.  To solve these problems the tool shank has a rosette-profile driving collar which engages with a similar rosette-profile machined at the entrance to the bore of the machine spindle nose. The collar on the tool shank consists of two round-cornered squares (4,5) machined one behind the other simply to produce in end view a rosette of eight circular area.  These fit with clearance into the similar shaped bore mouth of the spindle and provide a large area of contact for torque transmission.  One corner on the tool and in the spindle nose are made to a slightly smaller radius so that the tool will enter at only one angular position. USE/ADVANTAGE - Esp. suited to modular tooling systems for turning, milling and boring operations on machining centres.  REduces noise and wear.  Better torque transmission, esp. to small cutters.

Abstract: The air is fed through the timber stack in two phases, viz.: A) a heating phase, in which heating air with a temp. between 50 and 100 deg.C and a relative humidity of 50 - 100% is fed through the stack, causing the timber to absorb moisture, and this during a period of 2 - 60 min., B) A drying phase in which low temperature air with a relative humidity is fed through the stack, causing the timber to emit more moisture than it absorbed during the heating phase. In this phase, the drying air has a temp. of less than 50 deg. C., and a relative humidity of 0 - 100%, being passed through the stack during a period of 10 -100 min.. The heating air is heated by the supply of steam at a temp. of 100 - 200 deg.C. At least five drying cycles per set of timber are carried out. The timber in each drying cycle is made to absorb at least 0.2 kg of water per cbm of timber on heating, and to emit at least 0.3 kg of water per cbm. during the subsequent drying. The air in both phases is fed at a speed of 2 - 10 m/s.
