Abstract: This rotary switch is provided for electrical apparatuses, especially domestic apparatuses, such as washing machines, vacuum cleaners or the like. It has at least two switching links which can be moved via rotatable switching cams, are arranged above one another and indicate an open position and a closed position. The switching cams can be rotated by means of a common operating element. The operating element has two positions. Adjacent switching cams are coupled to one another. In order to construct a momentary-operation position, the rotary operating element can be turned on from the one stable position, against the force of a spring, by an angular amount into an unstable position. In this unstable position, both switching links move into their closed position. When the operating element is automatically reset by the angular amount into the one stable position, the one switching link remains in its closed position and the other switching link changes over into its open position.

Title: Swab moistening device
Inventor: ZANKER HELMUT
IPC: B05B11/04
Filed: 1986-01-29
Abstract: The invention proposes an improved moistening device for medical swabs which essentially comprises merely two components: a one-part, elastic hollow body and a prefabricated valve capsule, such that metered removal of liquid is possible by actuating the valve, which is designed as a pressure and suction piston, and by combined actuation of the valve in conjunction with the hood flexibly moulded on in the flexible hollow body. On depression, this hood effects a meterable air compression inside the hollow body. If the one-part hollow body is made of a very thin-walled, elastomeric material with several V-shaped articulations integrally formed on the cylinder wall, this hollow body can be suspended - depending on the working stroke required - with each of its articulation on a simple stand or a fork-shaped wall mounting. Another embodiment permits selective removal of liquid from the top or bottom of the suspended device. <IMAGE>

Title: Method for dissipating synchrotron radiation, and an electron waviness ring for dissipating synchrotron radiation
Inventor: TOMIMASU TAKIO
IPC: H05H13/04
Filed: 1986-12-11
Abstract: The betatron oscillation characteristic which is inherent to an electron storage ring is used for storing high-energy electrons, accelerated in an RF acceleration cavity while passing along a circular path which is defined by the design in order to produce undulating movements of the electrons, in such a manner that synchrotron radiation is dissipated from a point, to be precise from a point adjacent to a node of the oscillation of the electrons. High-intensity photons can irradiate a large area so that the synchrotron radiation can preferably be used for the production of extremely fine structures, as can be used especially in the transmission of VLSI circuit patterns, that is to say very large scale integrated circuits.
Patent DE-3644035-A1 (DE)
Title: Sheet separation device
Inventor: MUNZ ROLF DIPL ING
IPC: B65H5/06
Filed: 1986-12-22
Abstract: On a support (10) connected to a device generating a subatmospheric pressure, a suction element (11) is pivotably mounted. The suction element (11) is provided with suction openings and is spring-loaded in its pivoting-out direction. In the swung-out position, the suction openings of the suction element (11) are located directly on the topmost sheet, to be separated, of a sheet stack (23). By applying a subatmospheric pressure, the topmost sheet is drawn up, which fills the suction openings of the suction element (11). As a result the subatmospheric pressure increases further so that the suction element (11) is drawn against the carrier (10). In the process the front region of the topmost sheet is peeled off the sheet stack (23) and is transferred to a conveying device (21) for drawing the separated sheet off the sheet stack (23). <IMAGE>
