Title: Safety switch lock with inserted key - has locking lever which acts in conjunction with pressure centre lever
Inventor: MERKLE PAUL
IPC: E05B29/00
Filed: 1974-06-19
Abstract: The inserted key lock is used for a safety switch and has a longitudinally sliding locking insert and an intermediate lever pivoted outside the lock. The horizontal arm of this lever forms the locking lever for the switch handle. The locking of the key with the lock insert is caused by a pivoted lever with a locking lug which is bent at right angles. This locking lug forms the blocking element for the inwards movement of the locking insert in the locked position of the insert. In addition it prevents a downwards rotation of the rotating blocking lever while the locking insert is displaced. The spring loaded pressure centre lever rotates in the lock-housing and contacts in the outside position of the locking insert a sliding lug or a roller (29) of the lever (27) pivoted on the locking insert.

Title: Metal support disc for grinding wheels - dissipates heat generated during grinding and damps vibrations by grooves in wheel discs
Inventor: SCHWAEMMLE JAKOB
IPC: B24D5/16
Filed: 1975-05-15
Abstract: When using grinding rims built up from very small abrasive particles, a large part of the wear is due to heat generated and to vibrations. The wheels on which the grinding rims are mounted are made from metal, e.g. from aluminium which guides the generated heat away from the grinding area. To reduce the vibrations which are transmitted from the grinding machine to the grinding rims, the thickness of the wheel discs is locally reduced, e.g. by grooves which penetrate to a combined depth of about 50% to 80% of the thickness of the wheel. One or more grooves can be made in the wheel which can either be in line or off-set.
