 Appl.No PCT/EP1992/000939 Applicant HERAEUS QUARZGLAS GMBH Inventor LEBER, Helmut
A process is known for manufacturing rod-like preforms (3) for optical fibres by collapsing a tubular basic body (14). In order to improve such a process, so that preforms as fault-free as possible can be obtained, a rotating tubular basic body (14) is continuously and horizontally supplied into a heating zone. Outer and inner dimensions of the working body (14), the spacing between the boundary surface zone and the inner surface (13) of the basic body, the viscosity of the basic body (14) material in a collapsing zone, the difference between the inner and outer pressures, the height of the inner pressure, the preform haul-off-speed and the feed speed of the basic body are selected so that a stem (6) made of the core material of the basic body is formed from the collapsing zone in the opposite direction to the preform (3) hauling direction, in the axis of the basic body (14).

A manually sealable introducer sheath (10) is provided for percutaneous insertion into a blood vessel of a human subject which includes an introducer sheath having a proximal end and a distal end (23) with an elongated and generally cylindrical main body (20) which has a sealing valve (27) affixed to the main body near the proximal end. The main body has an essentially uniform outer diameter for most of the length of the main body, with the essentially uniform outer diameter extending to the distal end. Further, a manually insertable sheath sealing tab (40) is provided having a flexible hinge (42) molded onto the sheath near the proximal end. The tab further has a generally cylindrical stopper (44) which is releasably inserted into the sealing valve whereby the sealing tab structure allows the passage of a guideware (30) to extend outward from the proximal end when the stopper is inserted into the sealing valve.

11using an ionisation chamber for detecting smoke or gas
 Appl.No PCT/NO1992/000101 Applicant RENNEMO, Björn Inventor RENNEMO, Björn
Disclosed is a method and a device for measuring the smoke concentration in air. In a smoke chamber (5) are located two electrodes (2, 3), connected to a voltage source for forming a circuit in which a DC current flows. A radioactive radiation source (1) to ionize the air molecules is located in the vicinity of the smoke chamber, so that the number of ionized air molecules which are formed is dependent upon the radiation intensity of the ion source (1) and the concentration of smoke particles in the smoke chamber (5). The charging voltage will further imply that a cloud of high ion concentration is built up close to the surface of the electrodes. The ion cloud will be discharged capacitively upon a plurality of short voltage pulses (12) applied to the electrodes (2, 3) to thereby result in current pulses (13) substantially greater than the DC current flowing through the chamber (5).

 Appl.No PCT/US1991/009238 Applicant AVX CORPORATION Inventor SALISBURY, Ian
A binary electrical fuse (13) is comprised of a core wire (20) which is preferably relatively rigid, has a high ohmic resistance, and a high melt temperature. The core wire is clad with a metal (21) of substantially less rigidity having a low ohmic resistivity, and low melt temperature, i.e. in the range of from about 230 degrees C to 700 degrees C. The resistance of the core wire is at least about ten times the resistance of the cladding and preferably twenty or more times the resistance of the cladding. In the course of a fusing cycle the cladding metal will melt and pool, leaving the core wire as the sole conductor resulting in a rapid blow of the fuse due to the sudden high resistance load presented by the core wire.

A solder-bearing lead (10) for attachment to the surface of a substrate (39), wherein a discrete mass of solder (24) is mechanically held firmly by the lead (10) in a position permitting close proximity to the substrate surface to connect the lead (10) to the substrate (39) with an electrical and mechanical bond upon melting of the solder (24), the lead body having a pair of fingers (22) partially encircling the solder mass (24) with a gap (32) between the fingers (22) providing an unobstructed flow for the melted solder to the substrate. The lead may also be used to interconnect a first substrate (39) to a second substrate (44), forming a bond between conductive areas (45, 46) on both substrates.
