Abstract: The known carriages have set-down rollers arranged securely at the front end of a frame. With the carriage lying on the stretcher bearing support, these set-down rollers project further into the inside of the ambulance than do the running rollers of the stretcher itself. The use of the known carriages therefore requires that constructional changes be made to the stretcher bearing supports. 
<??>In contrast, the carriage according to the invention can also be used in the conventional stretcher bearing supports, without changes having to be made to the supports. 
<??>According to the invention, the set-down rollers (68) are arranged longitudinally displaceably on the frame (10), and at the front end of the frame (10) they can be fixed in their position relative to the frame (10) by means of a locking arrangement. By releasing the locking arrangement when pushing the carriage into the ambulance, the set-down rollers (68) push back relative to the frame, i.e. in the direction of the front legs (24), until they are finally situated directly under the front running rollers (78) of the stretcher (72).

Abstract: Disclosed is the solidification and chemical fixation of liquid wastes using biogenetic primarily amorphous silica to the waste in the presence of a strong alkali in the waste which converts the biogenetic silica into a soluble silicate, and in the presence of a polyvalent metal ion in the waste which reacts with the soluble silicate to provide a cementitious product of the waste. In the event there is insufficient strong alkali present in the waste to convert the biogenetic amorphous silica to a soluble silicate, and insufficient polyvalent metal ion in the waste to harden and form a cementitious product, amounts of these components as necessary can be added along with the biogenetic silica to the waste. The resulting cementitious and chemically fixed waste can be left in place, for example to provide a land farm, or can be removed and broken up and used as a cover for land fills, various land applications, and farms, as well as other applications.

Abstract: A storage container (10) for pastries, fruit, vegetables, potatoes or the like, is to be designed in such a manner that the vegetables mentioned, for example, can be kept fresh for approximately as long as has until now only been possible by means of keep-fresh refrigerators with integrated air humidification. This is achieved, in a storage container (10), which consists of a box (11) and a cover (12) which closes in an airtight manner, in that, inside the box (11), a water storage container (13) is formed or arranged. A water storage container (13) can, for example, be formed in the region of a side wall of the box (11) and moreover separated from the useful filling space (14) of the box (11) by means of a separating web (17). By means of the evaporation of the water, an increase in the air humidity is produced in the interior of the container, as a result of which stored goods can be kept fresh over a longer period of time than with conventional storage containers. <IMAGE>

Abstract: A mixture of telomers prepared by reacting chlorotrifluoroethylene with 1,1,2-trichlorotrifluoroethane (CCl₂FCF₂Cl) is purified by reacting the telomer mixture with potassium hydroxide in the presence of a quar­ternery ammonium compound and, optionally, a glycol, separating and removing impurities from the telomer mixture, subsequently reacting the telomer with potassium permanganate in the presence of the quarternery ammonium compound in a solvent, and recovering a purified telomer mixture. 
     If additional purity is required, the purified telomer mixture can be heated to a temperature of from about 150°C to about 250°C for at least 12 hours, and impurities formed during the thermal treatment are removed. 
     The purified telomers of this invention find uses in applications requiring the use of non-flammable hydraulic fluids.

Abstract: The invention relates to a method and an assay for determining the concentration of cyclosporin and its biologically active derivatives. The aim of the invention is to provide a straightforward method for determining the concentration of cyclosporins in biological materials. The measurement of the concentration of cyclosporins is important for monitoring a therapy in patients treated with medicaments which have cyclosporins as active drugs. The amount of cyclosporins in blood serum or plasma can be measured on the basis of the inhibition of peptidyl-prolyl cis-trans-isomerase by cyclosporins. The activity of this enzyme in the plasma can be determined by methods known per se. The method according to the invention quantifies with high accuracy the concentration of biologically active cyclosporins in the blood and is particularly suitable for monitoring therapy with these medicaments.

Abstract: Process for producing semiconductor devices, in which conductor tracks are formed on a surface of a semiconductor body by depositing a layer of Al(Si, Cu), in particular by sputtering, and then structuring it by etching. In such a layer, fairly large precipitates of CuAl2 which are only poorly etched, in particular, when etched in a Cl-containing plasma are formed at the boundary with the surface, and this may result in the conductor tracks having unsharp contours. In order to avoid such precipitates at the said surface and to achieve a homogeneous distribution of Cu in the layer, to form the layer, enough Al(Si) is first deposited just to form a continuous cohesive layer and then further Al(Si, Cu) is deposited in the same operation until the desired layer thickness is achieved. <IMAGE>

Abstract: A new bag cassette having a main bottom panel formed by a diagonal panel (18) defined by a pair of spaced parallel fold lines and a pair of side panels (20,22) is used to protect and position a bag and for squaring a carton. The bag spout (72) is held in a reinforcing panel (66) connected to the main bottom panel (12) by a spacing panel (56) and the bag is protected by the envelope formed by folding the two side panels perpendicular to the diagonal panel. To square a box having a cross section substantially corresponding with the periphery of the main panel, the cassette is inserted into the box with a diagonal panel extending diagonally between the pair of opposed corners of the box and with the side panels in folded enveloping position substantially perpendicular to the diagonal panel. As the cassette is moved down into the box it tends to force the box into squared position. Folding out of the side panels into a position parallel to the diagonal panel completes the squaring and positions the cassette in the bottom of the box.
