Inventor: WINKLER OTTO DR
IPC: F16K3/18
Filed: 1980-07-29
Abstract: Vacuum slide valve with a valve plate and an abutment, the pressing of the valve plate onto its seat being accomplished by means of an expanding mechanism between the two. When large contact pressure forces have to be transmitted, severe wear phenomena appear in the joints or bearings of the previous expanding devices. In order to avoid this, the invention proposes an expanding mechanism in which bodies (17, 18, 19) with cylindrical rolling-contact surfaces are rigidly connected to the valve plate (15), the abutment (16) and the reciprocating rod (20) and in which rotatable rollers (21, 22) are arranged between the rolling-contact surfaces. The said rollers are guided by cages (25, 26) in such a way that their axes and those of the rolling-contact surfaces are constantly in one plane. For use, in particular, in ultrahigh vacuum valves for the transmission of very large closing forces. <IMAGE>

Filed: 1980-09-12
Abstract: In order to be able to compare two RF signals with an integral frequency ratio without using a frequency multiplier in a phase detector, one solution consists in the fact that there are two branching circuits (16) which divide the respective input signal (f1, f2) in each case into two components with half power and a phase difference of 90 DEG . In each case two of these components of different phase and from different branching circuits are combined in a power adder (17, 18). At the outputs of the latter, diodes (2, 3) and RF short circuits (C1, C2) and an RF choke (19) with centre tap are connected. Between this centre tap (A) and the tap (B) of a potentiometer (6) blocked by RF chokes (4, 5), a direct voltage can be picked up if there is a phase difference between the input signals (f1, f2). <IMAGE>
Patent DE-3040819-A1 (DE)
Inventor: BAUER WALTER
IPC: G03B17/32
Filed: 1980-10-30
Abstract: A cassette for sheet film has a cover and a bottom which are hinged to one another along a longitudinal edge of the cassette. Locking elements for locking the cover and bottom when the cassette is closed are arranged at the opposite longitudinal edge of the cassette. The cover and bottom cooperate to define a film compartment and the bottom has a rigid, flat wall for supporting a sheet of film. The cover has a window for exposing the film in the compartment and is further provided with a slot which slidably receives a shield for protecting the film against light until such time as the film is to be exposed. A resilient rim is mounted on the cover and extends around the window. The rim is arranged to press the margins of the film against the rigid wall of the bottom when the cassette is closed. The hinged connection of the cover and the bottom causes the rim to contact the film progressively as the cassette is closed so that the rim stretches the film flat over the rigid wall of the bottom. The pressure of the rim on the margins of the film after the cassette has been closed insures that the film remains flat regardless of the orientation of the cassette.
