Patent DE-3045086-A1 (DE)
Inventor: PORRMANN HERBERT DIPL CHEM DR
IPC: A22C13/00
Filed: 1980-11-29
Abstract: 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 and 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. On its entire surface facing the film strip, the tubular casing has a substantially gas-impermeable and sealable layer, as has the film strip on the surface which comes into contact with the tubular casing. The film web is produced from viscose, and 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.

Title: Apparatus for the contamination-free transfer of articles between two spaces of different germ content
Inventor: DANIEL RUDOLF
IPC: B01L1/02
Filed: 1981-03-28
Abstract: The present invention relates to an apparatus for the contamination-free transfer of articles between two spaces of different germ content, which can also be described as a disinfection immersion lock. In principle, articles can be passed through the lock either dry or wet, in order to reach the SBF area, which is completely germ-free and is separated by a wall from the other space. The lock possesses a container and perfectly sealable apertures, so that the article to be transferred can be easily and quickly introduced and likewise removed again from the container of the lock. The actual invention resides in the fact that, dispensing with pumps and storage tanks, and with a relatively small volume of the immersion lock according to the invention, articles can be transferred easily and quickly and with increased safety between the spaces in question. The container is displaceable perpendicularly to the plane of passage and can be immersed in a sterilisation or treatment fluid for an adjustable residence time.

Title: Process for preparing trichloropropane or tetrachloropropane
Inventor: JOSTEN WALTER DIPL CHEM DR
IPC: B01J31/02
Filed: 1981-07-23
Abstract: The present invention deals with the preparation of  alpha , omega -trichloropropane or tetrachloropropane, which are prepared by reacting ethylene with chloroform or carbon tetrachloride in the presence of amines as catalyst. According to the invention, a dialkoxysilane or trialkoxysilane, which contains amino groups and which is immobilised on a carrier material, is employed as the amine catalyst. Immobilisation on the carrier material is effected by reacting the alkoxy groups of the amino silane with the carrier material. The latter is preferably a hydroxyl-group-containing material, such as, for example, silica gel, which is obtained by hydrolysing triorganosilanes or tetraorganosilanes. Minerals which occur in nature and which react with aminoorganoalkoxysilanes can also be employed as the carrier material. The advantages of the catalyst according to the invention are that it has a higher degree of selectivity and is readily separated off.

Patent DE-3139042-A1 (DE)
Title: Inductive proximity switch
IPC: H03K17/945
Filed: 1981-10-01
Abstract: An inductive proximity switch for alternating voltage comprising an oscillator as the detection element and with a switching element equipped with a semiconductor switch for switching a load. In such known switches, the quiescent current consumption exceeds a minimum value when the semiconductor switch is not turned on so that they cannot be used for this reason because some relays no longer drop off even with quiescent currents of the order of magnitude of 1.9 milliampere. As shown in the drawing, the quiescent current consumption of detection and switching element is limited by the invention to a minimum of, for example, 1.8 milliampere so that an inopportune response of the load is avoided. According to the invention, this is achieved by the fact that a Z diode (11) is used which can only be minimally loaded, for example up to 10 milliampere, and that at least one power transistor (13) and at least one drive transistor (12) for keeping the operating voltage across the oscillator constant independently of the magnitude of the load current are used between semiconductor switch (5) and rectifier. <IMAGE>

Patent DE-3147725-A1 (DE)
Title: Double-walled pipe
Inventor: HARDT GUENTER ING GRAD
IPC: F16L59/13
Filed: 1981-12-02
Abstract: A double-walled pipe, which is suitable for conveying hot fluids for example in high-temperature nuclear energy installations, consists of a ceramic inner pipe (1), a sealed metallic outer pipe (2) and, arranged between the two, spacers (3) in the form of circular ring segments which consist of a ceramic material having the same expansion coefficient as that of the inner pipe (1). The individual spacers (3) are pressed apart from one another in the circumferential direction by adjustable springs (4) so that, even in the case of different thermal expansion between the inner and outer pipe, a force-fitting connection to the latter is produced. Special pieces (9), which project somewhat beyond the outer surface of the spacers (3) and consist of a ceramic material having a relatively high strength, although with less-favourable heat transmission characteristics, are arranged on the contact lines between the spacers (3) and the outer pipe (2). The connection between the spacers (3) and the inner pipe (1) is positively locking via circumferential grooves in the latter, into which grooves the spacers engage. <IMAGE>

Patent DE-3149984-A1 (DE)
Title: Beaming machine
Inventor: ALDER GUENTER
IPC: D02H5/00
Filed: 1981-12-17
Abstract: The winding beam (62) is preceded by a pair of rollers consisting of a transport roller (64) and of a pendulously suspended tension-measuring roller (65). The transport roller (64) is arranged in front of the tension-measuring roller (65), as seen from the tending side of the beaming machine (61). The pendulum excursion of the tension-measuring roller (65) is great enough to ensure that, when the machine is at a standstill, the tension-measuring roller can be laid against the transport roller so as to clamp the textile material (71). The textile material (71), coming from a preceding comb (72), is guided rectilinearly to the transport roller (64), looped around the transport roller (64) over more than half the circumference and then looped around the tension-measuring roller (65) over part of the circumference. The textile material (71) is then guided rectilinearly to the winding beam (62). The object is to achieve better accessibility and a better possibility of monitoring the beaming machine, at the same time with a simplification of the machine design and a reduction of the constructional height. <IMAGE>

Title: Process and device for the biological purification of phosphate-containing waste water
Inventor: REIMANN HANS DR
IPC: C02F3/30
Filed: 1982-02-23
Abstract: In the process, the input waste water is aerobically treated in an activation tank in the presence of activated sludge for the degradation of organic hydrocarbon compounds and for the uptake of phosphate by microorganisms present in the activated sludge, the waste water/activated sludge mixture is withdrawn from the activation tank and fractionated in a secondary sedimentation to give purified, essentially phosphate-free water and phosphate-containing sludge, at least part of which is recycled as return sludge into the activation tank; a device for carrying out the process is also described. In the activation tank, the aerobic treatment is carried out in at least two treatment zones. A part-stream of the input waste water is fed to at least one further treatment zone, while all the return sludge is passed to the first treatment zone. The aerobic treatment in the first treatment zone is carried out for a period of time which is sufficient for the majority of the phosphate present in the waste water to be taken up by the microorganisms. A part-stream from this treatment zone is then fed to the second treatment zone and a further part-stream is subjected to phosphate elimination. At least part of the low-phosphate sludge produced from the phosphate elimination is fed to the first treatment zone, while the phosphate-enriched liquid produced is further treated.
