Title: Multi:platen hot press ensuring uniformly horizontal lift - has four pairs synchronising cylinders with pressure control unit
Inventor: BEYRER KARL-RICHARD ING GRAD
IPC: B30B15/24
Filed: 1979-05-22
Abstract: During the closing of the movable crosshead of a multi-daylight, hot press for chipboards, hard fibre panels, etc. the hydraulic fluid expelled from the differential or annulus chambers of the synchronising cylinders, enters the forward side chamber of one of each pair of synchronising cylinders, assembled for pref. with one pair at each corner of the crosshead. During the lowering of the crosshead, the hydraulic medium to be expelled from the forward side chambers is returned to the annulus chambers, but the forward side of one cylinder of each pair is not loaded with fluid. It ensures that the lifting and lowering of the moving crosshead and the platens carrying the materials, takes place as uniformly as possible, so that the highest possible degree of quality and accuracy of the prod., together with continuous working of the press are achieved. The platens are lifted smoothly and parallel without any spilling of the materials. When pressing is carried out without spacers, the nominal spacing between the platens can be ensured easily.

Title: Continuous simultaneous determination of several gas components - determining pressure drops in tube system performing specific vol. variations
Inventor: MOEHLENBECK KLAUS-JUERGEN ING
IPC: G01N7/00
Filed: 1980-03-20
Abstract: A method of continuously determining one or more components simultaneously in gases is implemented using a device which operates with high immunity to temp. and air pressure variations and which is simple to calibrate. The gas under test flows through a series of tubes between which its vol. is varied in a manner specific to each gas component. The pressure drop in the tubes is a function of the gas component examined in each section. The volumetric flow may be held constant before and after the point at which the gas vol. is changed. The differential pressure w.r.t. the atmosphere may be held constant at several points in the system. The gas is brought to a water vapour condensation point at a temp. lower than that of the tubes before reaching the tubes.

Patent DE-3111368-A1 (DE)
Title: Endoscope
Inventor: LANDRE JOHN K
IPC: G02B23/24
Filed: 1981-03-23
Abstract: In an endoscope having variable magnification, which can be set between a wide-angle position of low magnification and a telescope position of high magnification, an objective is provided with a diverging front lens and a converging rear lens. A diaphragm is provided between the two near the focal plane of the converging lens. In order to set a high magnification, the distance between the objective and a transmitting optical system including an eyepiece is increased and the diverging lens of the objective is brought into contact with the object to be viewed. The diverging front lens makes a relatively small contribution to the aberrations in the position with high magnification. In the case of low magnification, the diverging front lens cooperates with the converging lens and forms a wide-angle objective. Stabilisation of the pupil is achieved by selecting the position of the diaphragm in such a way that the diaphragm is virtually ineffective in the position of high magnification. The maximum numerical aperture is thereby determined by the diameter of the converging lens. However, the diaphragm becomes effective in the position of low magnification. A field lens situated in the vicinity of the image plane in this case receives the edge beams of the light bundle at an angle which is virtually constant over the entire range of magnification. As a result, it is possible to accomplish transmission of images by conventional means, for example using alternating field lenses and intermediate lenses.
