Abstract: A process for greatly improving the yields of cephalosporin nucleus produced by fermentation is described. Cephalosporin C-producing microorganisms are fermented in the presence of an acetylesterase enzyme so that cephalosporin C formed is immediately converted into desacetyl cephalosporin C before any non-enzymic degradation occurs. Fermentation to produce desacetyl cephalosporin C enables yield increases of cephalosporin nucleus of about 40% to be realized, and greater increases are possible if the fermentation is extended. The preferred cephalosporin C-producing organism is Acremonium chrysogenum, and mutants thereof that are capable of producing esterases in situ. Alternatively, esterases obtained from a variety of other sources may be added or formed in situ, for example from a strain of Rhodosporidium.

Abstract: An oxygen sensing element (10) for use in a device to detect oxygen concentration in a gas atmosphere or to detect air/fuel ratio in an internal combustion engine based on the oxygen concentration in the exhaust gas. The element is a lamination of generally flat and relatively thin layers including a shield layer (12) of a ceramic material, first solid electrolyte layer (14), inner electrode layer (16), second solid electrolyte layer (18) and outer electrode layer (20) laid one upon another in the mentioned order. The second solid electrolyte layer (18) and the two electrode layers (16, 20) constitute a concentration cell. The first solid electrolyte layer (14) is formed of essentially the same material as the second solid electrolyte layer (18), so that there is no or little difference in thermal expansion coefficient between the two layers (14, 18) which tightly sandwich the inner electrode layer (16) therebetween.

Abstract: Fighter pilots generally use an oxygen gas mask. Normally, the mask is held against the face of the wearer by bands which are fastened to the sides of the wearer's helmet. Under violent g-loads, the band is not able to hold the mask in proper position. This major problem is solved by the invention in that the mask is fastened to the helmet instead by a fastening arrangement which consists of a system of hinges and links arranged on both sides, which in vertical direction rigidly join the mask to the sides of the helmet, while the link system can move in horizontal direction. <IMAGE>

Abstract: Method for storing thermal energy in a combined open/closed system for improving the operation conditions of a heat pump installation employing water from e.g. a lake, a river or the like as its heat source. During the warm season, water is passed from the lake etc. through a tube system installed in bottom sediments of the lake at and/or below the level at which natural heat energy storage can occur. This results in an artificial heat energy storage in said bottom sediments. During the cold season, the lake water is passed first through said tube system to thus acquire a higher temperature and then from said tube system to said heat pump installation. Thus the water not only serves as the heat source for the heat pump but mainly serves as a heat transporting means by which heat energy is carried into the bottom sediment store in summer and is carried out of said store in winter. By optimizing the tube system layout in the bottom sediments in relation to the heating requirements typically arising during the cold season it is possible to establish a reserve of heat energy which every year is gradually consumed during the cold season and then again built up during the warm season.

Abstract: The identification of a mobile radio station in a radio transmission system may be based on a subscriber number allocated to the mobile radio station which is, for example, listed in the telephone directory and on an identifier formed according to a secret code rule from the subscriber number. By copying the answerback unit, e.g. a magnetic card on which the subscriber number and identifier are stored, or by eavesdropping on the exchange of information between the mobile radio station and a fixed radio station (radio switching centre) transmitted on the radio transmission channel, a manipulator can imitate an identifier belonging to another subscriber. In order to identify this imitation, additional data which vary during operation of the mobile radio station are combined with the fixed data (subscriber number and identifier of the mobile radio station) and evaluated in the radio switching centre. Varying data of this type may, for example, comprise the number of successful attempts made by the mobile radio station to log onto a radio transmission channel.

Abstract: The component (35) with the projections (40) can be pushed into a position where the film is maintained flat, and in which the projections (40) are facing the base (37). This enables the film to be clamped along at least two opposite edge areas between the base and the outer edges of the projections. In the free position of the component (35), the projections are at a distance from the base, allowing the film to be moved freely. Each projection (40) comprises a body of soft, elastic material fixed to the component (35), and each with an outer edge for pressing against the film (38). They are in inclined position so that the edge surfaces are located nearer to the film edge to be pressed than the position where they are attached to the component. When their edge surfaces are pressed against the film, the projections attempt to bend outwards, thus producing a stretching of the film simultaneous with it being pressed against the base (37).
