Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed is a tubular casing of fiber-reinforced regenerated cellulose comprising a film web which is curved to form a tube.  The edge regions of the film web, which run parallel to the longitudinal axis, abut or overlap slightly and are sealed by means of a film strip which covers both the edge regions.          The film web and the film strip composed of the same material have, in the wet remoistened stage, a breaking strength of about 15 to 30 N/mm2 and an elongation at break of about 30 to 50% in the longitudinal direction of the web, and a breaking strength of about 15 to 35 N/mm2 ar.d an elongation at break of about 30 to 50% in the transverse direction of the web.  The breaking strength in the transverse direction of the web is equal to or greater than that in the longitudinal direction of the web.  The adhesive layer is smoke-permeable and is preferably composed of a material system which sets without a chemical reaction.  The film web is produced from viscose, and it is prevented from shrinking during the process and is stretched in the transverse direction during drying.  The tubular casing finds particular application as a sausage casing.

Abstract: INVENTION:  A LONGITUDINALLY ADJUSTABLE SKI POLE            ABSTRACT OF THE DISCLOSURE           A longitudinally adjustable ski pole is pro-vided with two tube sections arranged telescopically movable into each other and are provided with a latch and several catches. When shortening the ski pole  a spring is tensioned.  An extending of the ski pole in longitudi-nal direction is caused by the tensioned spring.  The switching element is arranged, for instance, at the rear side of the hand grip of the ski pole.  The latch is supported at the outer of the tubes  and the catches are located at the inner of the two tubes.  The catches are formed as a through hole through the tube  and comprise a supporting shoulder provided with a supporting face.          The latch is arranged at a tilting lever which is spring biassed and operationally connected to a switching member.  The entire mechanism for the longitudinal adjust-ment of the ski pole is arranged in the grip section of the ski pole.  This grip section can quite easily be mounted to the common ski pole tubes.  The ski pole is intended specifically for cross-country skiers who can adjust the pole during the skiing proper to three various lengths  whereby a chosen length is arrested by a form closed locking of the two tubes telescopically inserted into each other.  The latch may be brought by means of the switching member into an intermediate posi-tion, in which it does not engage into any one of the catches  such that no locking of the two tubes is present such that an elastically yielding ski. pole is provided.

Abstract: Abstract of the Disclosure A conduit consisting of a metal tube, with or without a plastic tube liner, is rendered strain accommodating by securing to its ends fittings that have a first component part to one end of which is joined the usual male or female coupling means or other connector means and to the other end of which is joined a sleeve which, in turn, is connected either directly or through another component part to the metal tube end.  Said sleeve is joined to the component part or parts with provision for limited axial and angular movement and a fluid-tight seal therebetween.  The plastic lining tube when present may be independently connected to the first component part with a fluid-tight seal or may pass therethrough.  Alternatively, a short section of plastic tubing is connected with fluid-tight seals between the two component parts when present or between the first component part and the sleeve.  Thereby, the fittings can move through a restricted range relative to the metal tube while the plastic liner or tube section elastically accommodates such movement and fluid integrity is maintained independently by both the plastic and metal tubes.

By utilizing a set of three basic control signals carried by the bus, three distinct addressing structures can be established: master-to-master, master-to-slave, general master-broadcasting to all units in accordance with a number of chronologies and transmission modes. In a particular variant, substitutions of addresses can be performed directly on the bus.
