Abstract: A fiber tuft feeder includes a reserve chute; a feed roll supported in the reserve chute at an outlet thereof; a countersupport cooperating with the feed roll for defining therewith a nip through which the feed roll draws fiber tufts from the reserve chute; an opening roll supported immediately downstream of the nip for receiving fiber tufts from the nip; and a feed chute having an inlet connected to the outlet of the reserve chute. A relative motion of the feed roll and the countersupport toward and away from one another is permitted for varying the distance between the feed roll and the countersupport by the fiber tufts passing therebetween. Further, a spring is provided which resiliently urges the feed roll and the countersupport towards one another.

Abstract: An apparatus for irradiating fluids includes a conduit (11) through which the fluid flows, in which a static mixer (21) is disposed and which passes through a cooling vessel (16) having an annular cross-section. This arrangement is surrounded by several U-shaped fluorescent tubes (19, 20), whose legs, extending parallel to the conduit, are distributed around the periphery of the conduit (11). The mixer (21) effects a highly turbulent flow, such that all parts of the fluid are uniformly irradiated with radiation. If the fluid is a glue which is to be preactivated by the radiation, then the turbulent flow and the reaction rate, which is reduced by the cooling, retard the setting of polymerized fluid components on the inner wall of the reaction conduit, and thereby also inhibit the gradual blockage of the conduit (11).

Abstract: A window system is proposed in which windows (41) which can be both locked and tilted mechanically are connected via microprocessors (43) to a monitoring center (49) which can display the locking and closure status of the individual windows (41) via visual display units (51, 57). The microprocessors (43) are located in the vicinity of the windows (41) and connected to the receiver (61) of a radio-controlled remote control unit by which the windows can be remotely controlled. The windows (41) can also be controlled via an operating unit (65) in the monitoring center (49). The remote control unit may involve either portable transmitters (63) or transmitters with a fixed location (67) which control the windows (41) via sensors (69) as a function of ambient air parameters, such as the relative air humidity, temperature or the CO.sub.2 content of the air in the room. The windows (41) have a locking drive integrated in the handle and a separate tilting drive.

Abstract: A brushless direct current motor is energized by a power stage. Switches of the power stage are selectively switched by an electronic control device. In order to determine the correct commutation pattern, without using rotor position indicators, the control device is arranged to tap the power fed to the motor. The samples received by the motor, in an ordered sequence, define an analogue function whose parameters can be determined by vector addition. The computations applied to the sample enable the necessary commutating information and signals to be generated in a particularly rapid manner.

Abstract: In a double belt press, in which the steel belts are supported on the back by rollers, inherent compressive stress occurs on the side of the steel belts of a double belt press that are supported on the back by rollers, resulting in an undesirable bowl-shaped deformation of the steel belts. In order to avoid this deformation, at least the side of the steel belts which faces away from the rollers is subjected to treatment by shot blasting before being installed in the double belt press.

Metering pumps (5, 6) each have as pump devices communication bellows (21, 22) which are joined on the housing side with pump housing (2) and on the output side with the common actuating device (3). Actuating device (3) is a lever-type device mounted in a swiveling manner around a swivel seat (11) on one side in a head part (10) of pump housing (2) axially projecting over supply containers (18, 19), for conducting limited pump strokes.

Abstract: A lid (1) is injection-molded of polyethylene, for a widemouthed barrel of a synthetic resin, and includes an outer rim (4) encompassing the barrel neck (3) and an inner rim (5) dipping into the barrel neck. The outer lid rim (4) and inner lid rim (5) form an annular space (7), an annular web (8) projecting axially from the base of this space. For producing the lid gasket (13), the annular space (7) is exposed to an open flame for activating the annular space surface. Subsequently the sealing material, preferably polyurethane, is injected from a foaming machine into the base of the annular space (7), and thereafter the lid (1) is vibrated in order to degasify the gasket (13). The sealing material, preferably consisting of foamed polyurethane, contains a parting compound having a long-term effect.
