Title: Burring chamfering method
Inventor: TAKAHASHI TAMIO
IPC: B24B9/00
Filed: 1983-09-02
Abstract: @ A method of burring and chamfering a workpiece (2) employes an apparatus including: a workpiece carrying belt conveyor (3); one or a plurality of elastic grinding wheels (4) obliquely disposed over the belt conveyor (3), the grinding wheels (4) being arranged in parallel to each other in the same direction; and split-type press rollers (5X, 5Y) disposed along both sides of each of the grinding wheels (4). The method comprises the steps of: passing the workpiece (2) under a first grinding wheel (4X) wich has a grinding surface rotating in the direction opposite to the moving direction of the workpiece (2) thereby to effect burring and chamfering; and passing the workpiece (2) under a second grinding wheel (4Y) which is disposed in parallel to the first grinding wheel (4x) and has a grinding surface rotating in the same direction as the moving direction thereby to effect burring and chamfering. The grinding wheels (4X, 4Y) may be rotated while having an angle of about 45 degrees with respect to the moving direction. The moving direction of the belt conveyor (3) may be changed every time a predetermined time elapses. Moreover, the grinding wheels (4X, 4Y) may be vibrated in an axial direction of the grinding wheels.

Abstract: A changing apparatus for a standard six-high rolling stand comprises a changing carriage having a pair of similar full-set holders each provided with two vertically spaced working-roll supports and two vertically spaced backup-roll supports flanking the respective working-roll supports. These supports are vertically spaced like the respective rolls in the stand. Thus a full set of two working and two backup rolls can be held in either of the holders. The changing carriage can be displaced between upstream and downstream positions to axially align with the rolls in the stand. A loading carriage has a working-roll holder with two vertically spaced working-roll supports and a backup-roll holder with two vertically spaced backup-roll supports, the carriage being displaceable into a position with the working-roll supports of the working-roll holder aligned with the working-roll supports of one of the full-set holders and a position with the backup-roll supports of the backup-roll holder aligned with the backup-roll supports of the one full-set holder. The rolls can be axially shifted from the loading carriage holders into the one full-set holder, rolls are then axially shifted from the stand into the other full-set holder, and rolls in the one full-set holder are shifted into the roll stand.

Abstract: In a wide picture format television transmission system the signals for the scene (1,2,3,4) are transmitted as first and second television signals. The first television signal contains signal information relating to a portion (1, 5, 2, 6) of the scene of standard aspect ratio whilst the second television signal contains signal information relating to the remaining portions (1, 2, 3, 5 and 1, 6, 3, 4) of the scene. The first television signal can be compatible with television signals currently broadcast. In order to enable the first television signal to relate to the area of main interest of the scene it may be derived from a moveable portion between extreme portions (1,2,3,7 to 1, 8, 3, 4) of the scene. In order to correctly combine the information from the first and second television signals at a receiver for a correct wide picture format display the second television signal additionally comprises a component in the form of a steering pulse.

Abstract: Device for the automatic time-delayed closure of windows or doors with swinging or tilting leaves, having a tension member (29) which can be wound onto a drum (7) and by which the window leaf or door leaf can be connected to the associated frame. In the drum (7) there is a restoring spring (32) which is tensioned by the unwinding of the tension member during the opening of the window or door. To slow down the closing operation, there is a brake device which brakes the drum and which has a disc assembly (6), between the braking faces of which is arranged a high-viscosity fluid, for example silicone, as a braking medium. The drum (7) mounted rotatably on a stationary bearing journal (2) on the base plate (1) at the same time forming the spring core of the restoring spring (32) is equipped with a hub (25), concentrically with which is arranged an annular body which is rotatable only in the unwinding direction by means of a direction detent (18, 19, 20) and which is connected non-positively to the hub (25) of the drum (7) via the disc assembly (6) and the brake fluid contained in this. Delay times of several minutes can be obtained thereby.
