Title: Roll emulsions centrifuged and assessed visually - through transparent plate of centrifuge covering disc shaped zone
Inventor: THEOBALD REINER ING GRAD
IPC: G01N9/30
Filed: 1980-12-06
Abstract: A method of determining the proportions of the lighter components of centrifuged liquid mixtures, esp. the free oil component of a roll emulsion, is claimed. The image data (viewed data) of the components as they separate into concentric rings is optically viewed in one of the radial planes (i.e. from an axial direction) and from this the volumetric proportion of the individual components is determined by establishing the thickness of the various rings by measuring the radial distance between various light-dark or colour transitions referred to the gap geometry. The viewing data may be obtained photographically, photo-optically, or photoelectrically. Used partic. for rolling emulsions used in the rolling of sheets and strips. The effectiveness of the emulsion in removing heat and thereby maintaining the correct temp. is highly dependent upon its compsn. The method enables the compsn. to be rapidly assessed. .

Title: Method for preventing dirt-accumulation in eaves gutters
Inventor: LOWINGER SIEGFRIED
IPC: E04D13/064
Filed: 1981-12-04
Abstract: The aim is to prevent dirt- and mud-accumulation in eaves gutters in the simplest and most effective manner possible. By covering the gutter with e.g glass cloth of appropriate grid size, leaves for example are prevented from falling into the eaves gutter. By appropriate shaping of the gutter, wherein the gutter narrows towards the base into one or more small gutters, deposition of mud is prevented and at the same time a higher flow rate of the water in the narrowing is achieved, which has the effect of an automatic flushing of the gutter. Owing to the lateral slopes, the deposition of mud on these faces is prevented, and the dirt particles slide into the region of the narrowing and are carried away there by the higher flow rate of the water. <IMAGE>

Title: Opto-electronic angle measuring device, particularly for navigation purposes
Inventor: ZLOF DIETER
IPC: G01C1/08
Filed: 1982-01-04
Abstract: A lens (1) inclined by approximately 45 DEG  images the object area between horizon and zenith in the image plane (3). The beam deflection unit (2) inserted into the beam path makes it possible to displace the image vertically. The respective position of the beam deflection unit preferably built up of rotating prismatic wedges is converted into an analogue electrical measurement value. This measurement value stands for the respective vertical angle of an object point imaged in the centre of the image plane (3), referred to a device-internal so-called reference plane (4). The respective deviations of this - virtual - reference plane (4) from the ideal horizontal measurement position are also detected as analogue electrical values and correct the actual measurement. For this purpose, light reflected from pendulum mirrors (34) or a mercury bubble level (46) is detected by opto-electronic receivers (37) and a comparison circuit (33a/b) and correspondingly converted. In the automatic measurement of the elevations of sun and moon, the lateral deviation of the optical axis (8) from the object to be measured must also be detected as an analogue electrical value for the measurement value correction because of the omission of an accurate visual sighting. For this purpose, two separate images (28) of the sun or of the moon are generated by beam division (19) in a further imaging beam path. Field stops (24) arranged in opposite directions and having wege-shaped apertures (23), provide opto-electronic receivers (22) arranged behind them with different light flux components, depending on degree and direction of the lateral deviation, the total sum always remaining the same. The final measurement value corrected in this manner stands for the vertical angle of the measured object above the true horizon. It is captured at the instant of the precise direction finding by a measurement value storage pulse, also generated, and is stored. In the central logic (41), a complete nautical position information is generated, including the measurement time - obtained from the timebase (42) also integrated - , with the cooperation of an integrated microprocessor and electrically stored nautical data. The measurement value storage pulse is manually triggered in the case of visual direction-finding operations with inserted target marker. In the automatic measurement of sun or moon elevations, the beam deflection unit (2) is brought into an end position. After manual triggering, it automatically runs into the other end position. The measurement value storage pulse is generated in the storage signal converter (25) at the instant at which sun or moon image are located in the reference plane (4) with their vertical centre. For this purpose, the image is again split off by beam division (19) and the measurement value storage pulse is obtained by an opto-electronic comparison circuit in the storage signal converter.
