A compact, high sensitive, multi-wavelength spectral analyzer capable of simultaneously obtaining a spectral distribution of extremely weak radiation such as bio-luminescence, chemiluminescence, extremely weak fluorescence caused by excitation light, Raman scattered light, etc., with extremely high luminosity and without wavelength scanning, is disclosed. The spectral analyzer comprises a spectros...

A feeder (2) and a delivery device (3) each have an associated non-stop stack changer station, whereby a changeover process is initiated when a defined limiting stack height is reached. When the limit is reached the sheet path is interrupted for a defined period to produce a gap (L) in the sheet flow through the machine. When the gaps arrive the machine is successively switched off and then starte...

The detector field (16) of the scanner is comprised of a large number of detecting elements (18). The detectors are arranged such that the gap between them is reduced, which increases the resolving power of the scanner and therefore gives improved images. The detector elements are shaped as parallelograms and are arranged in a regular diamond shaped mesh. The detection elements of the detector are...

The fine lamina indents (17) in the profile elements (14) of the tread of a tyre are provided with wall areas which are structured in a three dimensional fashion and restrict, both in the lateral and in the radial direction, relative movements between wall areas lying opposite one another in order to improve the driving behaviour and the wear behaviour (eruptions, irregular abrasion) of such lamin...

The travel information system uses a swivel mounted display (10) mounted on a car dashboard. It may be turned towards the driver or passenger side. By means of a switch the display may be set to show traffic information or entertainment channels (TV). An interlock switch permits only traffic information displays when the screen is turned towards the driver. The entertainment source may also be a v...

In the speed stage shifting carried out by a speed stage shift pattern in an engine driving mode or a speed stage shift pattern in an inertially running mode according as the vehicle is running in an engine driving condition or an inertially running condition, when the vehicle is running in an indefinite condition between the engine driving condition and the inertially running condition, the engin...

A process for filtering out solid particles from liquids and backwashing the filter operates with a filter drum 5 arranged completely beneath the liquid surface 6, the circumferential surface 7 of which filter drum is covered with a filter medium 8 and through which the flow passes from the outside to the inside. Any backwash apparatus for removing the filter cake from the filter medium 8 is provi...

The adhesive-coated strips (11) are taken off the end of a conveyor (1) by pick-up plates (9). The strips are directed over a shaped lip (5) formed by a hollow duct (7) and there are air jets (6) on the downstream side of the lips. This provides an airflow under the lifted strips and passes them to the air-cushion support surface (20). The air jets are spaced along the lip and are shaped to provid...

A method and apparatus are provided for obtaining measurements from a wellbore during tripping operations. A drilling sub is attached to the drillstring adjacent to or as near as possible to the drillbit before commencing normal drilling operations. Prior to commencing tripping operations, a logging tool is engaged within the drilling sub. The engagement of the logging tool within the drilling sub...

A tampon for feminine hygiene having an absorbent core and a cover disposed around the core which is permeable to body fluids, the cover being provided with flexible barrier strips which are spreadable from the tampon surface. The barrier strips serve to close the space between the tampon surface and the walls of the vaginal duct when the tampon is inserted, preventing leakage especially in the ti...

The invention relates to a process for the production of substantially non-alcoholic beer by a continuous yeast treatment at a low temperature. In the process, wort which has been clarified and possibly treated by evaporating and/or with an absorbing agent is passed through a packed column reactor containing immobilized yeast at a temperature ranging between the freezing point of wort and +10 DEG ...

Method and device for automatically verifying that a note or document which comprises a watermark is genuine. A capacitive sensor device 4, 6, 7 is used which is divided into two and double-acting. A symmetry characteristic of the sensor output signal is changed in a predetermined way when a correct watermark is present in a coinciding position with condenser electrodes 4, 6 of a suitable shape. <...

A rigid polyurethane foam obtained by foaming a special polyol component and an isocyanate component in the presence of a blowing agent comprising water and at least one member selected from the group consisting of 1,1-dichloro-2,2,2-trifluoroethane and 2,2-dichloro-2-monofluoroethane possesses balanced excellent properties, has no surface void, and shows only slight expansion after molding. There...

The image obtained is digitised and the faults are classified according to n size classes. The fault classes (F1...Fn) are used for the classification of a non-emulsified output product. These fault classes are compared with fault classes (G1...Gn) obtained using photo carrier material with an emulsion coating. Measurements are carried out at further examples and the values for the weighting facto...

In a process for mfg. foamed material using a carbon dioxide blowing agent, one reactive component is mixed under pressure with liquid carbon dioxide and the mixture is combined with a second reactive component before passing through a relaxation appts. where the flow is divided repeatedly into individual streams with varying shear rates of 200-2000/sec.. Process appts. includes a claimed relaxati...

In a process for mfg. foamed material using a carbon dioxide blowing gent, one reactive component is mixed under pressure with liquid carbon dioxide and the mixture is then mixed again with a second reactive component before passing through a relaxation device (10) where it is divided into smaller streams with a shear rate of 500/sec. The foam is then relaxed and expands before setting. Process ap...
