Patent DE-3106778-A1 (DE)
Title: Saddle-rotating and swivelling device for forging presses
Inventor: JENKE DIETER
IPC: B21J13/03
Filed: 1981-02-24
Abstract: The invention provides a saddle-rotating and swivelling device for forging presses which is equipped with a rotating shaft vertically mounted on or in the moving part of the press and having a rotary operating mechanism, the said shaft engaging firmly in terms of rotation and tension in the foot of the top saddle via a hammer head arranged at its bottom end. The axle of the rotating shaft for rotating the saddle is arranged eccentrically in a rotating sleeve which is mounted vertically, rotatably and centrically relative to the press axis in the machine frame. Given eccentric suspension of the saddle on the rotating shaft and the maximum eccentricity of the latter relative to the press axis, the centre of the saddle is centric to the press axis. As a result, it is possible to rotate an outer edge of the saddle into the press axis for forming purposes. Special loads exceeding those in normal forging thus do not occur.

Title: Device for the belaying of sheets, in particular for sailing boats
Inventor: MOELLER FRIEDRICH DIPL ING
IPC: B63H9/10
Filed: 1981-02-27
Abstract: So that the trimming sheets serving to trim sailing boats can be adjusted from both sides of the boat, they are normally run to both sides of the boat and belayed there by clamps in order to be able to adjust them from the respective windward side dependent on the boat course. Since this arrangement does not provide trimming or full trimming travel under all circumstances, in the device according to the invention a tiltable or rotatable link (6) is arranged between two opposite sheet clamps (4a, 4b). Upon actuation of one of two sheets (1a, 1b) which are firmly attached to the trimming application point, the link (6) lifts the correspondingly opposite sheet (1a, 1b) out of the sheet clamp (4a or 4b) allocated to it, so that alternatively only one of the sheets (1a or 1b) is belayed in each case. <IMAGE>

Title: Fundus oculi camera having automatic focusing
Inventor: TAKASHI JUNICHI
IPC: G02B7/28
Filed: 1981-04-24
Abstract: A fundus oculi camera is specified, which can be switched optionally between automatic focusing and focusing by hand. The camera has a projector, a photosensor arrangement, a focusing control device and an illumination system. The projector projects a first and a second focusing mark onto the fundus of an eye that is to be examined. The first focusing mark, which is reflected by the fundus oculi, is detected by the photosensor arrangement, whose output signal is input into the control device, in order in this way to focus the camera. The illumination device illuminates the fundus uniformly with light in a first wavelength region. The first focusing mark is generated by light in the first wavelength region as well as in a second wavelength region different from the first, whereas the second focusing mark is generated only by light in the first wavelength region. The fundus oculi camera has, furthermore, a wavelength filter mirror which separates the light of the first wavelength region from the light beams incident on the photosensor arrangement.
