Patent DE-3635092-A1 (DE)
Title: Chemisorption filter having a rigid case and compressible surface seal
Inventor: HOELTER HEINZ DIPL ING
IPC: B01J20/28
Filed: 1986-10-15
Abstract: It is known to incorporate chemisorption masses in filters for air purification in order to filter out odour substances and hazardous constituents from breathable air. Such chemisorption filters must be exchanged for new ones at more or less regular intervals. In order to make this exchange simple and rapid, retaining the full functionality of the filter apparatus, according to the invention it is proposed that the body 2 of rigid material, which encases the chemisorption masses 1, and the sides of the chemisorption masses 1 through which flow does not pass are fitted out above their rigid formation with an all-enclosing, pressure-modifiable compressible seal 4, which lies air-tightly against the fitting 5, eg. portable or case apparatus or piece of furniture. <IMAGE>

Title: Wear-resistant lining for containers, in particular drum mills
Inventor: ZIEBART SIEGFRIED DIPL ING
IPC: B02C17/22
Filed: 1986-11-04
Abstract: The invention relates to a wear-resistant lining for containers, in particular drum mills. Such mills are used for grinding ceramic masses, paints and the like.   The aim of the invention is to provide a highly wear-resistant lining whose production is to be relatively simple, and the mounting and replacing of the lining is to be possible with a relatively low manual labour requirement. For this purpose, there are provided, in the cylindrical section of the mill container, wear webs of polyurethane pourable elastomer, which are initially straight but adapt to the inner wall of the mill container and are of a variable length which can be adapted to the inner circumference of the casing. At the edges, the wear webs have overlapping seams, the seam of the respectively outer wear web extending into a radial recess in the coating of the side walls. The width of the wear webs also permits them to be mounted through the manhole of the mill container. The field of application of the invention is the ceramic or chemical industry. <IMAGE>

Patent DE-3639717-A1 (DE)
Title: Device for generating water vapour
Inventor: ZEFFNER LUDWIG JUERGEN
IPC: F24F6/02
Filed: 1986-11-20
Abstract: In devices for generating water vapour to humidify the air it is usual to heat the water indirectly by heater elements or to pass electricity through the water by means of electrodes. Both methods suffer from high consumption of energy and an evaporation capacity that depends on the proportion of lime in the water. In the case of the heater elements, this is due to the limescale deposits and the resultant poorer heat transfer, and in the case of electrodes, the limescale deposits cause an increase in the contact resistance. The invention remedies both these problems regarding energy consumption and the demand for uniform output by having the container with the water positioned at least partly in a microwave field generated by a microwave generator. Direct absorption of energy by the water molecules occurs, so that lime in the water can have no effect on the heating up. Furthermore, at the surface the separation of water molecules into the vapour phase is promoted, providing savings in energy as well in a surprising manner.

Patent DE-3701333-A1 (DE)
Title: Photopolymerisable material
Inventor: HELLER VOLKMAR DR RER NAT
IPC: C08F2/48
Filed: 1987-01-19
Abstract: The invention relates to a photopolymerisable material which is suitable for the production of information-recording materials, for the production of relief images for printing plates and of printed circuits, and for the production of image-wise exposed surface coatings. The object of the invention is to provide a novel initiator system of high sensitivity in the visible spectral region for a photopolymerizable material having improved mechanical properties. This object is achieved by the fact that the photopolymerisable material comprising base, monomer, binder and optionally further additives contains a photoinitiator combination comprising an H or electron donor and an H or electron acceptor and a coinitiator (onium compounds). On exposure, the donor and acceptor form free-radical pairs, where the first part of the free-radical pair preferably initiates the polymerisation directly, while the other part of the free-radical pair preferably reacts with the coinitiator. Products which themselves initiate the polymerisation are likewise formed here.

Patent DE-3710739-A1 (DE)
Title: Surface aerator
Inventor: NEMETZ HERBERT
IPC: B01F3/04
Filed: 1987-03-31
Abstract: The invention relates to a surface aerator for the fine-bubble aeration of waste water having a rectangular plan, the supporting part, i.e. the baseplate thereof, consisting of fibre-reinforced plastic. The essentially planar baseplate (2) is furnished with a surrounding outwardly directed tensioning flange (2.1), which is offset at a distance from, and in parallel to, the bottom plane, which flange makes possible the positive-fit suspension of the edge region (3.2 and 3.3) seamlessly joined to the perforated part (3.1). The stepped baseplate (2) forms, together with the cover (3) an air distribution space (2.4) to which is connected at least one respective air connection branch (2.2). Due to generally transversely offset slots, partially to the main tensioning direction, or accumulation of the perforation punctures in the clamping regions the tension of the perforated part is decreased and the extent of dishing reduced. This causes an equalisation of the air distribution. <IMAGE>

Title: Gravitation coil
Inventor: ETZIEN HERBERT
IPC: H01F5/00
Filed: 1988-01-02
Abstract: When the French physicist Coulomb probed the analogy between the laws of the electricity and force of the universe, it was found that it would also provide technical gravitation. As an autonomous product, as a supplement to electromagnetic coils, in the case of non-ferromagnetic materials and as a component, when alternating current is used as well, for the construction of gravitation fields and machines, the gravitation coil overcomes the fact that technical gravitation was not discovered by Ampére, with all the possibilities for commercial application of the gravitation coil with a large number of turns of thin ferromagnetic wire or with a small number of turns of thick ferromagnetic wire to bringing the gravitation coil into use, electrical energy, as electrical current flows through.
Patent DE-3800463-A1 (DE)
Title: Street map viewer for drivers of cars, buses, and lorries (trucks)
Inventor: CHRIST EUGEN
IPC: G09B29/00
Filed: 1988-01-11
Abstract: The object of this invention is to make it easier for the driver to find his way while driving. It is no longer necessary constantly to reorientate oneself when viewing a street map, which is due to the fact that the axis and the direction of the path travelled do not coincide with the axis and the direction of the path indicated on the map. A street map is located on a map holder or is held the hand, with north pointing upwards; during each change in direction while driving, the map always shows the direction to the north, as it is fixed, while the path travelled leads in another direction. Thus the driver constantly has to "re-think" his position to find his way. If the directions of the map always were to correspond to the four points of the compass, finding one's way would be much easier. The street map viewer solves this problem in that one or a plurality of components of which it is composed - image screen, image transmission system, map holder, projector - assumes the additional function of a compass in the form of a main compass or a sub-compass and freely rotates, similarly to the rose of a compass according to the directions. The street map viewed by the driver rotates in accordance with the directions.

Title: Method and device for protecting measuring elements arranged in gas streams against soiling
Inventor: SASS WOLFGANG DIPL ING
IPC: G01F1/00
Filed: 1988-01-19
Abstract: For protecting measuring elements, particularly air mass flowmeters such as ceramic measuring chips, arranged in gas streams, in particular in air streams in the engine induction channel of motor vehicles, against soiling by moving foreign particles such as water droplets and dust, it is proposed that the foreign particles in the air stream are first ionised and then deflected away from the measuring element to be protected in a high-voltage field. The foreign particles can, as it were, be diverted around the measuring element, so that this remains free of foreign particles and can deliver exact measured values over a long lifetime and without servicing.
