Title: Disc brakes
IPC: F16D65/14
Filed: 1973-02-27
Abstract: 1421039 Slack adjusters SEGARIC SA 27 Feb 1973 9683/73 Heading F2E An automatic adjuster for a spring applied electromagnetically released disc brake in which one pad 4 is applied via a rod 5 and the other 3 by reaction as the caliper slides, has two adjustment spacers 9, 9<SP>1</SP> for compensating wear of the friction linings 41, 31 and for maintaining a constant magnetic air gap (e). In the inoperative position of the disc brake, a movable armature 62 is applied against the pole faces of a yoke 61, and through a ring 64 compresses the apply spring 7 and releases the shoe 4 from the disc 2 by means of a spring 8 which transmits a force through a washer 81 to a stop ring 82 and spacer 9<SP>1</SP> sufficient to keep a spring washer 66 compressed against a stop ring 67. To apply the brake, the excitation of electromagnet 6 is cut off and spring 7 pushes ring 64 and armature 62, and through spacer 9 the shoe 4 to the right. The rod 5 follows this movement, spacer 9<SP>1</SP> being correspondingly moved by washer 66 until it abuts a shoulder 65 at the same time as the lining 41 engages the disc 2. If lining wear has occurred, spring 7 continues to expand so that the magnetic air gap (e<SP>1</SP>) becomes greater than desired. The stop ring 82 then separates from the spacer 9<SP>1</SP> which is relieved of compression forces and a torsion spring 96 located between the ends of rings 91, 92 having helical bearing surfaces 94, 95 of irreversible pitch causes rotation of one of the rings, the other being fixed, so that the spacer 9<SP>1</SP> is extended in axial length. On re-excitation of electromagnet 6, armature 62 must carry out a displacement (e<SP>1</SP>) in order to contact yoke 61. Since spacer 9<SP>1</SP> can move only a distance (e) due to the adjustment, spring 8 is compressed to a value (e<SP>1</SP>) - (e). The compression on the spacer 9<SP>1</SP> is thereby relieved causing its spring 96 to rotate one ring relative to the other until the extension compensates the stroke supplement (e<SP>1</SP>) - (e). A rotary lever 5 may be used to relieve the braking if electromagnet 6 fails.

The position of the record size arm and hence stop 9 is set by member 18 which is activated by a record size control. Horizontal pivoting movement is imparted to the pick-up arm by horizontal movement of the operating lever 11 when plunger 16 has engaged the underside of pivot arm 5 after the lever has been vertically pivoted to raise the pick-up arm. When the pick-up arm is lowered the rod 6 carries the stop 9 to a position below arm 5 so that the pick-up arm is free to play the record.

Filed: 1988-06-14
Abstract: PCT No. PCT/AT88/00045 Sec. 371 Date Dec. 6, 1989 Sec. 102(e) Date Dec. 6, 1989 PCT Filed Jun. 14, 1988 PCT Pub. No. WO88/10502 PCT Pub. Date Dec. 29, 1988.The invention relates to an arrangement in an on-load change-over switch of an on-load tap changer for uninterrupted switch-over of the regulating winding of a transformer. On-load change-over switching is usually accomplished using mechanical switching elements. Burning of contact and contamination of oil are disadvantageous. Furthermore, there are known constructions which use a combination of mechanical switching elements and thyristors for on-load change-over switching. The disadvantage of such arrangements is mainly the too great constructional expenditure for the control elements which are liable to breakdown. According to the invention, the on-load current is supplied to a common output line via a lower winding tap or a higher winding tap of a regulating stage of a regulating winding, and through at least two selector contacts and two permanent contacts whereby the switch-over from the lower to the higher winding tap, and vice versa, is effected via a change-over switch which briefly switches the on-load current to a load relief circuit which is arranged between the root connection of the change-over switch and the common output line. The discharge circuit could comprise, for example, two thyristor circuits, the thyristors of which are connected in antiparallel, one of these thyristor circuits being connected in series with a transition resistor.
