Patent DE-4009110-A1 (DE)
Title: Plastic packaging film with localised high strength areas - has co-extruded strips of different materials with higher strength material corresponding with areas of high loading stress
Inventor: UTZ KASTULUS
IPC: B65D71/00
Filed: 1990-03-21
Abstract: A plastic packaging film is extended, before location around an object, and then returns its original size, sealing the object at the same time. The film is formed into a tube by co-extrusion of two different material strips which run parallel to the tube, and at right angles to the direction of intended extension. The two materials have different tensile and recovery properties, the first having high extension and recovery, the second low friction and/or high resistance to mechanical stress. Strips are arranged such that the material with the higher mechanical resistance is located in areas which correspond with damage prone areas on objects to be covered e.g. edges.

Title: Rotating boring bar with fine diametral adjustment - has two=part bar with tool end radially adjustable by rotation of eccentric enveloping sleeve
Inventor: SCHEER GERHARD
IPC: B23B29/034
Filed: 1990-07-19
Abstract: The rotating boring bar consists of a nose section (10) and a shank section (16) linked by a connecting piece (12) and partly enveloped by and adjusting sleeve (18). The nose end is recessed for a tooltip (22) clamped to a slide (20) which provides coarse diametral adjustment. The linked ends of the nose and shank sections are of reduced dia. (28, 30) and have cross-slots which engage with cross-ribs (40, 42) disposed at 90 deg. on the connecting piece (12). The connection thus formed is  torsionally rigid but permits relative lateral movement of the two sections. The adjusting sleeve (18) has bores (32) and (34) which are a close fit on the reduced ends (28) and (30) but are slightly eccentric to each other. In consequence when the sleeve is rotated on the boring bar the radial position of the tooltip is very precisely adjusted. A tension rod (14) passing through the centre of the boring bar holds the two parts firmly together. USE/ADVANTAGE - Compact, rigid design of boring bar permits fine boring of small holes.

Title: Magnetic data transmission procedure to wheels of railway vehicles - safeguarding by utilisation of portions of wheels less affected by temp. for binary code read-out
Inventor: VOIGT HEINZ DR RER NAT
IPC: G06K1/12
Filed: 1990-10-08
Abstract: A coil (26) wound on a ferromagnetic yoke (25) of, e.g. dynamo iron laid between the rails (24), is excited with electric current (I) producing magnetic flux (phi) in a circuit completed through the wheels (21, 22) and axle (23). The radial portions (21a, 22a) of the wheels are magnetised nearly to saturation so that remanent magnetisation can be detected as stray flux by contactless magnetic sensors near the inner faces, whose temp. is not materially raised by conduction of heat from the brakes through the tyres. ADVANTAGE - Degrading influence of tyre heating during braking on magnetisation is reduced.

Patent DE-4036901-A1 (DE)
IPC: F16L37/36
Filed: 1990-11-20
Abstract: It is the object of the invention to indicate a coupling which takes better account of environmental conditions and is suitable for refuelling. It relates to a quick-acting coupling with a locking means (58-61), releasable by manual actuation, for bringing two coupling halves into a coupling position relative to one another. Two through channels, of which one (K1) serves for the introduction of liquid and the other (K2) serves for the escape of air, are equipped with two closure valves (V1, V2), which are closed simultaneously when the coupling halves are separated. A control sleeve (23), which can be displaced by a piston (20) that can be acted upon by auxiliary medium on both sides, forms free end faces (27, 37) against which a sealing ring (29) assigned to the two through channels (K1, K2) rests in sealing fashion. When the control sleeve (23) is displaced, the two channels (K1, K2) are simultaneously opened. This quick-acting coupling is also equipped with a proximity switch (22)and there are induction coils (46, 47) for transmitting data to a recording device.   <IMAGE>

Title: Biological waste-water treatment - with comminution and aeration of recycle activated sludge to prevent bulking sludge formation
Inventor: ZIETZ UDO DR
IPC: C02F3/12
Filed: 1991-05-06
Abstract: Biological waste-water treatment is effected in a plant comprising a pre-clarifier, an activated-sludge (AS) tank and a post-clarifier. The sludge suspension from the post-clarifier is comminuted to break up of flocs and then oxidised with air before being recycled to the AS tank. The sludge suspension is pref. coarsely screened and then passed through an impeller mill or nozzle to reduce the floc size by 10-30%, esp. to 10-80 microns. The sludge suspension is then aerated for 5-50 (5-25) min in the presence of 1-10 mg/l Fe(2+) or Fe(3+) as catalyst. ADVANTAGE - The process prevents bulking sludge formation by preventing build-up of filamentous microorganisms.

Title: Multistage reactor for treatment of waste prods. - comprises sepg. waste material after each stage and partly converted into gas phase, by exchange of thermal energy
Inventor: SCHOEN CHRISTIAN O
IPC: C10M175/02
Filed: 1991-05-07
Abstract: Method and equipment for preparing fluid organic waste products, containing reusable or harmful constituents. A multi-stage single-duct reactor is used in which an exchange of energy (e.g. of thermal energy) with the waste product takes place and the waste product is at least partly converted into a gas phase. After each stage the harmful constituents from it are sepd. into a sump, in each stage the necessary activation energy (previously determined experimentally) is applied, and after the last stage the required product is condensed. The reactor throughput is kept constant by the regulator (7). At the end of this first stage (2) there is a separator (8) for the product entering the sump (10) and the product changed into a gas phase. The latter product leaves through the pipe (11) and its temp., measured at (12), is communicated to the burner control so that the burner is kept at a constant temp. The second and third stages (16,17) are similar to the first stage, but the third stage has no dosing arrangement for additional chemicals. From the third stage, the product goes to a condenser (18) and discharge pump (19). A vacuum pump (20) provides for the necessary underpressure in the system. USE/ADVANTAGE - This is an improvememnt on a single-duct reactor in (P 38 20 317.0-45) has an increased range of use and is easier to construct. Also, it enables two valuable constituents, such as used mineral and vegetable oils, to be sepd.

The procedure is then repeated with subsequent shees. USE/ADVANTAGE - Sheet guiding system for a printing machine. The system can operate at high speed.
Patent DE-4115212-A1 (DE)
Inventor: MERZ ALBERT DR
IPC: G01N15/06
Filed: 1991-05-10
Abstract: The invention relates to a process for the continuous determination of the dust content of flowing media with the isokinetic flow sampling with the separation of the dust or aerosols by cake filtration on a filter and the measurement of the pressure drop at the filter to determine its degree of clogging. To this end the time cycle of the quantity of dust separated on the filter is determined by the measurement of the pressure loss at the filter of an isokinetically operating sampling system. To find the dust load, this quantity of dust is related to the partial quantity of gas extracted isokinetically during the period concerned.
