Abstract: The present invention prevents coolant from leaking out of a valve (23) after a feed pump (4) stops feeding the coolant, and diminishes a time-lag between the onset of feeding the coolant and mist generation, when the feed pump (4) starts feeding the coolant again. In the machine tool of this invention, the coolant is fed from a feed pump (4) into a mist generating device (13) provided on the tip of a spindle (8) by way of a feed line (7), and a valve (23) is provided at an inflow part for coolant of the mist generating device (13) to be closed when the coolant pressure within the feed line (7) lowers below a fixed level. A coolant sucking and delivering (2) sucks a fixed amount of coolant in the feed line (7), when the feed pump (4) stops feeding the coolant. On the other hand, the device (2) feeds a fixed amount of coolant into the feed line (7), when the feed pump (4) begins feeding the coolant.

Abstract: Internal climate comfort in a living room occupied by human users is controlled by natural ventilation, through at least two external adjustable openings and at least one internal opening, said natural ventilation being determined from a constant physical parameter of said living room and measured parameters relating to wind load and temperature difference to approximate a target air exchange rate for the room. An adjustment parameter (S1, S2) for each external opening is determined to provide air exchange (Qf) to the room on the basis of said target air exchange rate and is modified by application of a set of individual comfort functions (&mgr;) for each opening, taking account at least of outside and inside temperature, air exchange and wind speed and direction. The individual comfort functions (&mgr;) of said set are weighed by fuzzy optimization to produce optimized and substantially equally distributed comfort conditions in positions in the living room adjacent each opening.

Abstract: A method to improve the stacking of containers comprising thermoplastic plastic, and the transfer of the stacks to a successive device. Stacks of a predetermined number are intended to be produced without disturbances, even with a high cycle number of the shaping tool. This is achieved in that the containers are stacked in a first stack magazine, which is exchanged for an adjacent stack magazine between two cycles of the shaping tool after the predetermined number has been reached. The containers are stacked in the stack magazines directly from the shaping tool, or by an intermediate transfer device.

Abstract: The transfer of stacks comprising molded plastic containers from stacking magazines into downstream devices in terms of susceptibility to disturbances, with the molding apparatus having a large number of cycles is improved. The method requires simple format parts, and permit a rapid format change when the apparatus is converted to a different container format. This is achieved be stack cages comprising stacking-magazine rows that can be displaced perpendicular to the stacking direction and removed from the other stacking-magazine rows. They are guided to a removal station, unloaded and placed onto the stacking-magazine rows remaining on the other side in the stacking station.

Abstract: An article, such as an impeller, is mounted for torque transmission by a shaft by positioning the article in contact with a threaded collar engaging tapered threads on the shaft and applying an axial force to the article to move and tighten the threaded collar on the tapered threads. The axial force is applied to the article by a clamping collar which contacts the article only in an area spaced from a central bore of the article in order to deflect a portion of the article defining the central bore radially inward toward the shaft. In one embodiment, two impellers are positioned back-to-back, with one impeller receiving an axial force spaced radially from a central bore of the impeller by an annular formation on the other impeller.

Abstract: An elevator includes a special propelling fluid dynamic device which uses as a plunger the duly balanced car counterweight. The car conveys people and things upwards and downwards within a vertical conduit or hoistway supported by a cable extending to an upper pulley. When changing the direction, a counterweight is extended to balance the car. The pulley is supported from the hoistway walls and is kept in a freely-rotating condition while the balanced counterweight is a hollow piston-counterweight, accommodated in the cylinder vertically disposed in the hoistway itself and adjacent to the car. Both are integral with the propelling fluid dynamic device that produces the upward and downward movements of the car, which is completed with a circuit having a fluid flow conduit and a driving pump coupled to the valve mechanism.
