Title: Method of cooling a milling tool, in particular at its cutting edges, and milling tool suitable for this method
Inventor: HOCHBERGER ERHART
IPC: B23F23/12
Filed: 1981-02-18
Abstract: To cool the cutting edges of a milling cutter accommodated on a milling arbor or the like, a coolant is fed to the cutter via bores in the milling arbor or the like. The coolant is directed through bores inside the cutter into the cutter teeth, where it discharges at the back of the cutter teeth and sprays onto the face or the cutting edges of the cutter tooth lying behind the respective tooth back. A milling cutter which can be used for this method is provided with approximately radially running bores which start from its centring bore and lead inside the cutter teeth into tangentially running bores which come out at the back of the teeth in such a way that these bores in each case lie in front of the tooth behind them. <IMAGE>

The images and, in particular, the differences, for example, in the crack which appears are then evaluated.
Patent DE-3110323-A1 (DE)
Title: Method and device for operating a heating system as a function of outside external temperature
Inventor: WINTERBERG HEINZ-JOERG
IPC: G05D23/24
Filed: 1981-03-17
Abstract: Method and device for operating a heating control guided by the outside temperature, in particular for hot water central heating systems, in which actuating signals corresponding to the desired/actual difference of the room temperature are used to control the temperature (tv) of the heating feed (9) as a function of the outside temperature, the feed temperature (t) controlled in accordance with the outside temperature additionally being lowered by a time switch (19) during a preprogrammed first time interval from a first temperature value (t1) by a prescribed first temperature difference to a lower second temperature value, the first time interval being followed upon expiry by a second time interval during which the feed temperature (tv) is raised to a third temperature value (t3) which is higher by a second temperature difference ( DELTA t2) than the first temperature value, and it being the case that a third time interval follows thereafter during which the feed temperature (tv) is lowered from the third value (t3) to the corresponding first temperature value (t1). In particular, the absolute value of the first temperature difference ( DELTA t2) depends on the outside temperature in such a way that it decreases in the direction of higher outside temperatures. As a result, in the event of low outside temperatures there is a greater feed temperature overshoot than in the case of higher temperatures, resulting in the achievement of a shorter heating-up time. Also proposed are circuitry implementations. <IMAGE>

Title: Invertor having between-phase commutation
Inventor: GOLDE ERNST DIPL ING
IPC: H02M7/521
Filed: 1981-03-14
Abstract: In the case of a self-commutated invertor having a smoothing capacitance between the DC voltage connections and having commutating capacitors which are in each case arranged in delta between the main valve branches in order to turn off the main valves in the phase sequence, it is intended to prevent charging of the commutating capacitors to a value which is higher than the DC voltage. For this purpose, the series circuit of a diode (n13 to n63) and of an impedance (r13, i13; r43, i43) is in each case connected between the branch connection of two commutating capacitors (k1 to k6) and a DC voltage connection of the smoothing capacitor (C), in such a manner that the charging current of the third commutating capacitor (k1 to k6) is diverted via this series circuit to the smoothing capacitor (C) as soon as the voltage on the third commutating capacitor (k1 to k6) exceeds the voltage on the smoothing capacitor (C). <IMAGE>

Title: Disc brake of the floating caliper type
Inventor: RUPPRECHT KURT
IPC: F16D55/00
Filed: 1981-03-27
Abstract: The invention relates to a disc brake of the floating caliper type, having a brake anchor plate, two brake shoes which are mounted in an axially displaceable fashion between two rigid arms, which axially overlap the brake disc, of the brake anchor plate, a fist-shaped floating caliper which is mounted on the brake anchor plate in an axially displaceable fashion and overlaps the brake disc and the brake shoes between the rigid arms, and a lining-holding spring which is respectively arranged on both the inlet side and the outlet side of the brake disc and by means of which springs clattering and rattling noises of the brake shoes are prevented. The lining-holding springs respectively extend over the length of the rigid arm and are arranged in such a way that a first force component which presses the brake shoes onto the sliding and guiding surface of the assigned rigid arm and a second force component which presses the brake shoes away from the supporting surface of this rigid arm become active. The two lining-holding springs are equal at the inlet and the outlet sides and are symmetrically arranged about the plane of the brake disc in the installed condition. They have at both their ends, with respect to the length of the rigid arms, stops which are at least approximately aligned with the end faces of the arms, project from the planes of the latter and by means of which the brake shoes mounted on the arms are prevented from laterally sliding off from the latter when the lining-holding springs have been mounted and the floating caliper has not yet been mounted. <IMAGE>

Patent DE-3119868-A1 (DE)
Title: Reel for coiling and uncoiling metal strips
Inventor: EXNER ROLF
IPC: B21C47/30
Filed: 1981-05-19
Abstract: The invention relates to the constructional design of a reel for cold rolling mills and to the construction of the hydraulic system for operating the reel. The new feature is that the expanding cheeks of the reel are supported in half-shells and these extend over the entire width of the reel (cf. Fig. III and IV). Between the pressure-medium pump and the piston for expanding the cheeks there is a stepped piston with an integrated non-return valve. By virtue of the design of the stepped piston, the pressure medium is pumped through the stepped piston if there is a pressure drop from the pump side to the expander piston side, while, when there is a pressure drop from the expander piston side to the pump side, the non-return valve closes and the pressure transmission ratio of the stepped piston comes into effect (cf. Fig. VII). Application of the invention: reel for cold- and hot-rolled strips subject to high coiling forces. Due to the summation of the coiling forces, the expanding cheeks are pressed together very strongly. In this context, the sturdy mounting and the pressure increase by way of the stepped piston represent a major advantage over previous solutions. <IMAGE>
