Patent DE-3800341-A1 (DE)
Title: Cutter blade for slate-dressing machine
Inventor: HOPPEN EWALD A
IPC: B28D1/32
Filed: 1988-01-08
Abstract: On a slate-dressing machine which works in a stamping manner according to the scissors principle, the most important thing is the design of the cutter blade. The security against fracture and the working speed above all depend thereon. The present invention indicates systematically the prerequisites for a favourable design. In particular, it is illustrated how, with a stamping cutter, even complicated capping slate formats such as capping bricks for old-German style covering are cut out automatically with a single tool movement. With one machine, which uses cutter blades according to the invention, the slate dressing takes place in an automated and fully industrialised manner. The central point of the invention is recognising that the cutting system is implemented in a linear and rising manner, in other words with a constant spot pressure.

Title: Protection against landing run extension, by means of additional thrust devices
Inventor: EICKMANN BODO DIPL ING DR ING
IPC: B64D25/00
Filed: 1988-01-09
Abstract: It is proposed to equip even inland lakes - particularly in mountainous areas! - with means and measures to allow damaged aircraft which are no longer capable of climbing over the surrounding mountains of still being able to make an emergency landing (to ditch) on the inland lakes. While P 3721346.6 explains the capability still to look for a suitable landing field by means of additional and independent thrust devices - in addition to the main engines - and possibly to fly over mountains, P 3812702.4 describes how passengers and the aircraft can still be rescued when an emergency landing is made on water - not only on inland lakes!

Title: Method for the immunological detection of substances, and a composition and a test kit
Inventor: NASER WERNER DIPL BIOL DR
IPC: G01N33/58
Filed: 1988-03-07
Abstract: The invention relates to a method for the immunological detection of substances, in which the said substances are incubated with reagents which contain constituents which have one or two of the following functions:   1. Specificity for the substance to be detected (specific constituent);   2. Direct or indirect detectability (detection constituent); 3. Production of a connection between the said specific constituent and the said detection constituent (bridge constituent) and the said constituents might be involved in the formation of multilayers; furthermore to a composition and a test kit which are suitable for the immunological detection of substances. The most sensitive immunological detection methods known hitherto have provided for multiple repetition of the incubation of the material to be investigated with bridging antibodies and enzyme immune complexes, it having been necessary to wash the samples thoroughly after each individual incubation step. The aim of the present invention is to provide a method and means with which immunological detections of particular molecules can be carried out with high sensitivity and low expenditure on time and effort. In the method according to the invention, a high sensitivity and a reduction in the expenditure on time and effort are achieved by the constituents involved in the formation of the multilayers ...

Title: Cylindrical side reflector for nuclear reactors
Inventor: HORNISCHER EDGAR DIPL ING
IPC: G21C1/07
Filed: 1988-04-19
Abstract: The invention relates to a side reflector, constructed from a multiplicity of graphite blocks, for a nuclear reactor having preferably spherical fuel elements, which is supported on a cylindrical metal construction. In order to prevent a collapse of the block construction, even on the occurrence of extremely unlikely accidents which have a failure of the cylindrical metal construction as a consequence, in at least several places on the outer shell of the side reflector, in each case two neighbouring graphite blocks are connected together by means of a connecting element which is arranged positively in a recess formed by milled cavities in the two block surfaces, and consists of a material which resists high temperatures. In the case of a corresponding configuration of the connecting elements, part of the operational side reflector loadings can be accepted by these elements, by which means the expenditure for the radial support elements of the side reflector can be reduced.

Patent DE-3827996-A1 (DE)
Inventor: FABIAN WERNER DIPL CHEM
IPC: B01D53/46
Filed: 1988-08-15
Abstract: In chemical processes, in particular the production of elements for the semiconductor technology, which are based on the material systems of the III-V and II-VI combination semiconductors, arsine, phosphine and hydrosulphide, highly toxic processing gases, are used as basic material. Said gases, which are generally designated as covalent hydrids of the pnictides (= N, P, As, Sb and Bi) or chalcogenides (= O, S, Se, Te and Po), can be very rapidly, from a quantitative and kinetic reaction point of view, removed from the residual processing refuse gases by the present process. The harmful substances are converted into their corresponding oxyacids using periodic acid as an oxidizing substance. Said process can also be applied to the production of elements based on the material systems of the elemental semiconductors silicon and germanium, where said gases are used as doping agents. The iodine generated during purification is converted to not easily volatilized iodide and iodate in a second gas washing stage by means of a comproportionation reaction with lithium hydroxide. Lithium iodate being the most water soluble of all the iodate salts, the absorber units inserted are not subject to bursting.

Patent DE-3831627-A1 (DE)
Title: Strengthening of gears
IPC: B23P15/14
Filed: 1988-09-17
Abstract: The strengthening method for gears with external or internal tooth system which have been finished to the correct size in a conventional manner is based on the fitting and joining by adhesive bonding, soldering and welding, especially electron-beam or laser-beam welding, of one-piece or multi-piece supporting rings which are inserted into grooves specifically provided for this and cut in the gear periphery. These supporting rings reduce the free length of the teeth and enable the teeth, during the strength calculation, to be considered as tips clamped on one side in the gear body or as tips additionally supported on one side or both sides. A considerable increase in the strength of the tooth root is thereby achieved, which leads to a further increase in the transmission power of the gear through distribution of the external loading over several neighbouring teeth. However, during unchanged external tooth loading, a reduction in the tooth-top deflection is obtained, which has a positive effect on the synchronism, the additional dynamic forces, and the sound pressure of the meshing teeth.

Title: Three-point pliers for breaking glass
Inventor: HERRMANN HEINZ
IPC: C03B33/033
Filed: 1988-11-18
Abstract: The invention relates to three-point pliers for breaking glass along a pre-scored line, having two jaws which are movable towards one another, one of which has a central projection and the other of which is designed as an abutment. To produce the break, the pliers must be placed on in such a way that the central projection is located on one side of the pre-scored line and the two-point abutment is located on the other side of this line. This requires precise alignment of the pliers in respect of the pre-scored line. If the pliers are not aligned correctly, the break may depart from the pre-scored line. In order to facilitate the work with pliers of the generic type described at the beginning, provision is made for the other jaw, in the form of an abutment, to have a protruding flexible elastic ring which surrounds the central projection when the jaws are pressed together.
