Title: Dental treatment unit with automatic presentation of selectable instruments
Inventor: ROSENFELDT WOLFGANG
IPC: A61C1/00
Filed: 1981-05-12
Abstract: The dental treatment unit is equipped with selection and actuating means for automatically presenting the instruments by means of mutually independent displacement from their holders from a rest position into a standby position in which the instruments can be gripped by a user's hand which operates the selection means (A, A2, ..., An, ...) and expects to be supplied with the instruments, according to main application P 3013882.0. A logic circuit (L) processes the removal signals, which can be triggered by means of removal signal transmitters (ES1, ES2, ..., ESn, ...) after displacement of the instruments into their standby position, for activating the supply units (V1, V2, ..., Vn, ...) of the instruments (J1, J2, ..., Jn, ...). According to the invention, the logic circuit (L) is preceded by a detection circuit (E) by means of which the logic circuit is supplied, from a time sequence of retrieval signals which can be triggered by means of the selection means, with the one which is the first one to last longer than a predeterminable minimum signal duration. The actuating signal allocated to this retrieval signal for operating the actuating means displacing the holders is output to the actuating means from the logic circuit. The result is that the last instrument selected is always presented and risks of injuries by operating errors are avoided. <IMAGE>

Title: Covering cap for control devices or switching devices which can be switched on and off by operating a pushbutton
Inventor: CSIKAI ALADAR
IPC: H01H13/06
Filed: 1981-09-11
Abstract: The invention relates to a covering cap for a control and switching device which can be switched on and off by operating a pushbutton or plunger. It has a cap retaining part with a retaining collar which can be inserted into an opening in a carrier such that it is mounted in a fixed manner. Provided in the retaining collar is an elastic pressure membrane (diaphragm) which is constructed like a bowl and whose edge is held by an outwardly directed edge piece on the inner circumference of the retaining collar. The covering cap is distinguished by a large pressing-in depth of its pressure membrane into the retaining collar, because its edge can at least partially be inverted inwards while it is being pressed so that valve plungers and similar control elements having relatively large displacement movements can also be advantageously operated. When the pressure membrane is pressed, a restoring force builds up in its deformed membrane edge which can return the pressure membrane completely to its original position once said pressure membrane has been released.

Patent DE-3203455-A1 (DE)
Title: Working implement
Inventor: MUELLER HEINZ
IPC: B26D7/24
Filed: 1982-02-02
Abstract: In the known handles for working implements, in particular working shears, which carry at one end a fixed shear blade and a driven shear blade movable towards the latter, in which the drive is arranged for the movable shear blade and which have, at the side, a releasing lever articulated at one end on the handle and movable at the other end towards the handle, additional means are required to prevent someone unintentionally actuating the releasing lever when the working implement is not in use but the operating means supply is connected and open. To avoid this, a catch which is displaceably mounted on the handle and pushed under the releasing lever by the end facing away from the articulation, and a spring which acts at one end on the catch and at the other end on the handle and which holds the catch under the releasing lever, are proposed. The operator has to push the catch away from under the handle before the shears can be operated. If the operator releases the shears, the spring immediately pushes the catch under the releasing lever, so that the drive can no longer be actuated.
