Abstract: A method of leak testing at least one "main" cavity (1) formed in a body (2), involving filling the main cavity with a test gas (6) at a determined pressure (PO). The leakage pressure variation (15, 16) in the main cavity is measured while reducing the pressure inside the main cavity in steps (dpn) by means of a controllable valve (12). The various values of leakage pressure variation, are compared with equal values being representative of a part that is leaky and with values that become smaller from one measurement to another being representative of the presence of at least one secondary cavity communicating with the main cavity via a seepage path (4) having high head loss. The two cavities taken together are possibly non-leaky.

Abstract: A digital time multiplexed mobile telephony system including a fixed base station and a plurality of mobile stations. For established connections the mobile stations are assigned channels, each corresponding to a time slot, from a plurality of time slots included in a time frame. The channels are assigned such that the mobile station to which the propagation time is shortest is assigned time slot 1, the mobile station to which the propagation time is next shortest being assigned the time slot 2, and so on. After the last time slot in the time frame there follows a guard time common to all time slots, for avoiding that the transmissions of the mobile stations wholly or partially overlap each other at the base station receiver.

Abstract: For cutting strands (1) moving at casting speed in a simple, trouble-free, low-maintenance and flue-gas free manner, a continuous casting plant is equipped with a flame cutting machine (2) in which the flame cutting roller table (13) consists, for example, of two independent racks (14) with stub support rollers (15) which can be set to strand width. With the flame cutting machine (2), they are designed and equipped in such a way that at no time do flame cutters (6) work above the strand support. The racks (14) of this cutting roller table can simultaneously be used for extraction of flue-gases produced in cutting. Slag granulation at the flame cutting machine can be dispensed with and a free line of sight under the strand for monitoring of cutting by means of a camera (24) at the end of the cutting roller table increases operational reliability.

Abstract: The connection of silicon nitride joint faces by hot pressing with interpositioning of silicon-containing layers which have more than the stoichiometric amount of nitrogen and less than the stoichiometric amount of nitrogen necessary for the formation of Si3N4 is expediently effected by providing a layered arrangement of two layers which have less than the stoichiometric amount of nitrogen, of the composition SiNx where 1.3 > x >/= 0 along the joint faces and an interposed layer with more than the stoichiometric amount of nitrogen, of the composition SiNx where x > 1.33, these layers essentially adding up to Si3N4. In particular, the outer layers with less than the stoichiometric amount of nitrogen have a composition of Si to SiN1.0. In a layered arrangement of this type, a layer with less than the stoichiometric amount of nitrogen which is easier to wet adjoins each of the joint faces, so that the overall strength achieved for the joint is increased.

Abstract: A method and apparatus as described for forming an optic fibre with a narrowly tapered end portion and a smoothly rounded tip. A predetermined tension load is applied to the fibre, a middle portion of the fibre is heated to soften it, and the tension is allowed to rapidly pull the heated middle fibre portion into a narrow taper and then to separate the fibre to form two fibres with narrowly tapered end portions. One of the fibres with a narrowly tapered fibre end portion can be formed with a rounded end by again applying heat, this time to the tip of the tapered end portion. The tension force is applied by a spring, or possibly a weight, to enable rapid acceleration of one fibre end portion away from the other, with the acceleration and speed limited primarily by the heat applied to the fibre.

Abstract: The tool, consisting of a shaft (1) and an insertion end (2), has axially closed longitudinal grooves (4, 5) which are open towards the rear end (3) and which are partially provided with a profiling (7) on the groove base (6). The profiling (7) has stop surfaces (9) acting essentially in the axial direction and it is formed by indentations (8), in which, for example, a lubricant can be arranged. When placing the tool in a receptacle of a drive device, dirt can be scraped off on the stop surfaces (9) and deposited in the indentations (8). In the manufacture of the longitudinal grooves (4, 5), the profiling (7) on the groove base (6) prevents an undesired change in length of the insertion end (2) by means of segments rolling off on the insertion end (2) in the axial direction, and it allows a sharp-edged rolling of the profile.
