Patent DE-3540828-A1 (DE)
Title: Tree protection device
Inventor: CZARNETZKI JUERGEN
IPC: A01G13/10
Filed: 1985-11-14
Abstract: The invention relates to a tree protection device, in particular for roadside trees. Vehicles driving past throw dirt particles, oil residues, rubbed off brake parts (e.g. asbestos) which are situated on the roadway, but also chippings and pebbles as well as other solid objects against the tree bark which is thus increasingly damaged. Particularly harmful in this case is the melt water which is formed in winter under the action of de-icing salt and which is not only thrown directly against the tree trunk but also seeps into the tree disk and thus damages the roots of the tree. A further harmful effect is caused by the exhaust gases of motorised vehicles, which are often deposited as a greasy condensate layer on bark, leaves and ground. The aim of the invention is to produce a tree protection which protects the tree trunk and a given part of the tree disc from the damaging influences indicated and impairs as little as possible the aspect presented by the tree. According to the invention, this aim is achieved by a curved wall which surrounds the tree trunk and which is fastened on two stakes driven into the bottom of the tree disk in such a manner that the tree trunk is fully or partially protected with a great free space up to a predetermined height against harmful effects of driving traffic and of dogs.

Title: Apparatus for introducing a textile web into textile finishing machines
Inventor: STEJSKAL MILAN DIPL ING
IPC: D06B23/04
Filed: 1986-05-15
Abstract: The invention relates to an apparatus for introducing a flat textile web into textile finishing machines, which is formed by a sensor for monitoring the edge of a textile web, by a motor, provided with a movement screw, for actuating one arm of the chain guide in the plane of the flat textile web, and by a circuit for actuating the motor. The object of the invention is to provide a simply constructed and reliably working apparatus having a long lifetime. The essence of the invention is that the apparatus is provided with a freely rotatable selsyn tilting unit fed with a harmonic voltage which is supplied either to the rotor (2) or to the stator (1), that a sensor for the edge of the textile web is mounted on the freely rotatable shaft of the rotor (2) of the selsyn tilting unit, that two harmonic phase-shifted voltages are taken from the stator (1) or the rotor (2) and are converted by means of a detector into a direct voltage, the magnitude and polarity of which are determined by the direction and magnitude of an intermediate-position deviation of the rotor (2), and that these voltages serve for controlling the speed and direction of movement of the motor. <IMAGE>

Title: Device for the disinfection of liquids by irradiation
Inventor: UEBERALL PETER
IPC: A61L2/10
Filed: 1986-07-17
Abstract: Ultraviolet disinfecting devices for liquids, preferably of drinking water, product water or bathing water, lead to design problems at high throughput, starting at about 50 m<3>/h, insofar as, on the one hand, it is impossible to connect any desired number of small disinfecting chambers one behind the other and in parallel and, on the other hand, conveyance of the liquid is not very simple in the case of large disinfecting chambers with a multiplicity of UV disinfecting lamps housed therein, because every water particle must be irradiated for the same period of time and with the same intensity in order to achieve a specific, average disinfecting performance. The disinfecting chamber, according to the invention, utilises the annular space between two or more concentric cylinders which corresponds to the space between two parallel plates which ensures rather a laminar flow in the circumferential direction and leads to further, very considerable advantages. In that the UV emitters are located only over a part of the circumference and there are no emitters within this circumference each UV lamp can be controlled separately via sensors. On the other hand, if the diameters and pressures are not excessive, the inner cylinder can be made of a material that is permeable to UV radiation and, if appropriate, the entire disinfecting chamber can be irradiated with a single, powerful UV radiation source which can moreover be installed in a dry place. In a UV disinfecting device of this design ... Original abstract incomplete.

Inventor: SCHULENBURG MICHAEL DR
IPC: C02F5/00
Filed: 1987-09-02
Abstract: In a process and equipment for treating circulation water of open circulation cooling systems, preferably in cooling tower circulation systems, a solution is to be found which simplifies the monitoring and treatment of circulation water of open cooling systems and, in particular, makes this possible over a long period without laboratory analysis and manual monitoring. 
<??>This is achieved in the process according to the invention by arranging that at a preferred location at least a part of the flow is continuously diverted from the circulation water and flows through a compact and standardised modular unit for the treatment of circulation water, in which successively and automatically, the pH of the partial stream of water is determined and, if necessary, depending on the measured pH, acid is metered in to establish a desired pH, the conductivity of the partial stream of water is determined, preferably inductively and, if necessary, depending on the measured conductivity value, a clarifying unit is activated, corrosion protective agent is added, if necessary, to the partial stream of water as a function of the amount of additional water added to the circulation water to make up for losses, at phased intervals organic and/or inorganic biocides are separately added to the partial stream of water through further metering devices and the partial stream of water is filtered in a filter with automatic back washing, and subsequently the partial stream of water is fed back continuously to the circulating water.

Title: Composite material
Inventor: UNGER GUENTER
IPC: B32B27/06
Filed: 1988-02-09
Abstract: The invention relates to a composite film (multilayer film), in particular a metallised, gas- and water vapour-impermeable composite film printed by counterprinting for packaging, in particular foodstuffs packaging. The feature of the invention is the sequence of the composite of a transparent polyester film printed on the composite side with printing inks based on soluble metal-complex dyes, an aluminium film vapour-deposited thereon in a high vacuum, and a polyolefin film laminated onto the aluminium film by means of an adhesive. The complex lacquering of the packaging material which was conventional hitherto thus becomes superfluous.
