Abstract: Abstract of the Disclosure In a process for the production of mat-formed material it is known to weight the mat as it moves in a horizontal path on a transport means. According to the present invention a continuously running, band-formed or mat-formed material, such as mineral wool is weighed continuously at a given point, and the sensed weight is used to control the speed of a conveyor arrangement along which the band of material is running.  The material is supported and transported along a first driven conveyor and onto a second driven conveyor spaced a short distance from the discharge end of the first conveyor.  The first and second conveyors are oriented to form an upwardly concave obtuse angle such that the band of material deforms and bends through an upwardly concave obtuse angle as it passes from the first conveyor to the second conveyor.  The band of material is continuously weighed as it passes between the first and second conveyors by passing the deformed and bent band onto and along a third non-driven idler conveyor located between the first and second conveyors and arranged to continuously sense the weight of the band passing therealong.  The first and second conveyors are driven at equal speeds, but the speeds are varied in response to weight changes sensed by the third conveyor means.  The third conveyor means may be in the form of a roller mounted in the space between the first and second conveyors. The method and apparatus of the present invention provide for accurate and continuous weighing of the mat material.

Abstract: ABSTRACT OF THE DISCLOSURE        A method and apparatus for correcting tracking errors of a transducer which scans successive, parallel, adjacent record tracks of n record medium so as to reproduce information signals therefrom.  The information signals, which may comprise video signals, are recorded in the parallel record tracks, and pre-determined signals also are recorded at predetermined locations in the information signals.  When the information and predeter-mined signals are played back, at least one cross-talk predeter-mined signal which is recorded in at least one adjacent track also is played back.  The cross-talk predetermined signal is detected and a control signal is produced    response to the level of the detected cross-talk predetermined signal.  The position of the transducer with respect to the track being scanned thereby is adjusted in accordance with the control signal.  In one embodiment, the control signal is recorded at a predetermined location in each horizontal blanking interval of the video signals; and the horizontal blanking intervals which are recorded in one track are displaced with respect to the horizontal blanking intervals which are recorded in the adjacent track.  This displacement of the horizontal blanking intervals, and thus the predetermined signals, in adjacent tracks facilitates the detection of the cross-talk predetermined signals which, for example, may comprise pilot signals.                             -i-

A plurality of strand-like fibers are wetted with a liquid, heat-hardenable plastic, the fibers are collected together into a plastic-wetted bundle, the bundle is continuously, in intermittent steps, passed through an elongated die, the die being heated in sequential zones of progressively increasing temperature so as to harden the plastic by the time the bundle emerges in rod form from the die.  The bundle is moved through the die intermittently, dwelling for a predetermined time at rest, then moved an incremental distance, permitted to dwell again, until the hardened bundle eventually emerges from the die.  The various heated zones of the die serve to initiate and carry the hardening of the plastic to a predetermined point at which the bundle is moved and the cycle is repeated.  In the first zone, the bundle is preheated to a point just short of the plastic becoming hardened such that upon movement to the next succeeding zone, which usually is at a higher temperature, the plastic is cured to a hardened stage.
