Fluoroplastics, for example PTFE, are ablated using laser pulses with a duration of 300 fs, a wavelength of 248 nm and a fluence between approximately 0.5 and 1 J/cm<2>. Under these conditions, the ablation rate is of the order of 1 micrometre per laser pulse.

In the case of a device for filling small tubular electrodes for lead-acid accumulators, a pressure tube (1) which is filled with pasty, active compound has outlet openings (2) along an envelope line. The number of these outlet openings (2) corresponds to the number of small mesh tubes (3) to be filled, and the pressure tube is surrounded by a rotating ring (8) having at least one pair of opposite...

A solenoid valve having permanent-magnet latching is described, which can be operated in a monostable or bistable mode depending on the status levels of the available external control circuit. In the monostable mode, a circuit having a capacator becomes effective, the charging current of which capacitor, when the valve is switched on, holds a circuit of the same in the position where it is latched...

Apparatus for finishing the edge region of panels for the interior lining of motor vehicles, having a bottom die (10) in the form of a rim, with a raised mould profile (16) whose corresponds to the form of the edge region of the panel (P), and having a press die (12) with vertical cutting elements (22), which for trimming the edge region of the panel (P) under the action of a press interact in the...

As is known, a radiation protection apron is a burden for an investigator owing to its high intrinsic weight, without offering whole-body radiation protection. Lead curtains on the X-ray equipment as a radiation protection are also found to be troublesome for the investigator and the patient. A radiation protection device (1) has an X-ray absorbing radiation protection shield, a freely mobile trol...

Novel, multiple-tritiated steroid-20,17- spirolactones of general Formula 1 wherein -A-B is -CH2-CH2-, -CH=CH- or and R is hydrogen or tritium and n is 0 or 1, are usable as tracer materials for the detection of mineralocorticoid receptors.

For feeding yarn to looms so-called yarn racks are used, on which are mounted protruding bobbin holders for receiving the yarn bobbins. In connection with large carpet looms there may be several thousand bobbins. The racks normally consist of welded frame structures with bobbin holders welded thereto, and it is a very demanding task to construct the racks and effect changes therein. By the inventi...

In the process for producing an aromatics concentrate suitable as a blending component for carburettor fuels, feed hydrocarbon mixtures of a boiling range essentially between 40 and 170 DEG C are subjected to an extractive distillation, without prior separation into individual fractions, the selective solvent used being N-substituted morpholines with substituents having not more than 7 C atoms. In...

PURPOSE:To prevent backflow of cracked gas at the time of switching by providing an interlocking device having an interchange mechanism for permitting operation from a small opening of the second switching valve to full opening after the first switching valve is totally closed at the time of closing the first switching valve. CONSTITUTION:An interlocking device 6 includes an interchange mechanism ...

The present safety ski binding is characterised in that it has a first tipping member which is mounted between a rear end part of the force-transmission member and the front parts of the two lateral holding wings or the transversely running support of these wings, and a second tipping member in the form of an angled-off lever which is articulated on the housing or the base-plate about a horizontal...

A bottle inspecting apparatus comprises means for conveying bottles while rotating the same; a first light source for exposing only the bottle finish with light; a second light source having a radiation spectrum different from that of the first light source for exposing the thread of the bottle neck; a filter for discriminating the light of the first light source scattered at the bottle finish and...

A novel, large-area, foldable standing umbrella is proposed which has a simple and inexpensive construction with the customary umbrella linkage but which is spread open without a special gear mechanism or telescopic linkage by a pulley-type cable and is retained by a ratchet. The retention can be released again by the same cable. The umbrella canopy forms a geometrical polyhedron and the umbrella ...

DNA strand having an ability in biotechnological production of alpha -acetolactate decarboxylase is disclosed. The DNA strand is characterized in that it has a nucleotide sequence coding for a polypeptide whose amino acid sequence is substantially from A to B of Fig. 1 and which has alpha -acetolactate decarboxylase activity. Also disclosed is a yeast which belongs to Saccharomyces cerevisiae an...

A process for producing a foamed polymer, particularly a foamed polyofefin, of highly uniform low density. A mixture of a polymer-forming material, a cross-linking agent, and a blowing agent is placed in a mould and reacted. This reaction product is cooled until the differential temperature between core and surface is below a predetermined maximum, and removed from the mould. The cooled product is...

In etching openings in polyimide film, the film is first etched with a basic reagent in its uncured or partially cured state to form the desired openings, and thereafter, the film is cured. However, this will leave a layer of disturbed material surrounding the openings which has absorbed some reagent and will not fully cure and, therefore, not provide topography suitable for reliable interconnecti...
