Title: Closed agitator mill with sieve cartridges
Inventor: STEHR NORBERT DR ING
IPC: B02C17/18
Filed: 1985-10-16
Abstract: A closed agitator mill for grinding and distributing solids in fluids has a grinding chamber (9) which is filled partly with auxiliary grinding bodies and in which is arranged an agitator (7) which is formed from an agitator shaft (21) and agitator tools (22) attached thereto and can be driven at high speeds and which generates a flow of material being ground and auxiliary grinding bodies. At least one tube-like sieve cartridge (26'', 28''), which can be replaced from outside and which projects into the space between the agitator shaft (21) and the grinding chamber wall and is used for separating the auxiliary grinding bodies (24) from the material being ground, is arranged in front of an exit (25) for the ground material of the grinding chamber (9). In order to achieve a satisfactory, largely wear-free separation of ground material and auxiliary grinding bodies (24), even in the case of highly viscous material being ground and/or high flow rates being applied, the sieve cartridge (26'', 28'') has a cross-section whose extent in the flow direction of the flow of material being ground and auxiliary grinding bodies in the grinding chamber (9) is greater than that perpendicular to the flow direction. <IMAGE>

Title: Disc-shaped tool for cutting-off and form machining
Inventor: WITTENBORN ROLF
IPC: B23D61/04
Filed: 1985-11-19
Abstract: Described is a disc-shaped tool having teeth, arranged on the outer periphery and in each case carrying a cutting edge, for the cutting-off and/or form machining of wooden panels, coated chipboards, plastic panels, hardboards or panels of Plexiglas or light metal, in which arrangement the cutting edge is formed by a first cutting-edge part (2), essentially parallel to the axis of rotation, at the cutting-edge tip and by at least one directly or indirectly adjoining side cutting-edge part (3), running in a plane at right angles to the axis of rotation, and cuts the edge of the workpiece (10). In order to improve a tool of the type mentioned at the beginning in such a way that a substantially longer service life is obtained while at the same time improving the cutting quality, it is proposed that the transition (7) from the tooth tip to the widest point (8) of the side cutting edges (3) be curved and that it merge tangentially into this widest point (8) of the tool. <IMAGE>

Title: Process and equipment for gasifying low-grade fuels in a reaction chamber containing a red-hot molten iron bath
Inventor: HENRICH GUENTER DR
IPC: C03B5/00
Filed: 1985-12-04
Abstract: In the gasification of low-grade fuels in an iron bath reactor, there is a risk of the molten iron freezing if insufficient heat is introduced. This problem can be overcome by partial combustion of the product gas generated. In a known process, an additional oxidising agent for the partial combustion is top-blown onto the iron bath through nozzles in the upper steel converter zone. It is disadvantageous in this case that only a small molten bath surface is available, that the nozzles are arranged at a distance of at least 2 m above the molten bath and a turbulent molten bath surface is generated, so that only poor heat transfer from the gas phase to the molten bath can take place and a major part of the heat is removed with the product gas from the converter. These disadvantages are eliminated by the invention by introducing the separate oxidising agent for the partial combustion of the process gas generated into the reactor almost parallel and close above the molten bath surface, approximately in the direction of the largest dimension of the reaction chamber.

Patent DE-3623528-A1 (DE)
Title: Engine with vacuum
Inventor: ULRICH JAKOB DR
IPC: F01L5/06
Filed: 1986-07-12
Abstract: In this "engine with vacuum" the oxygen is removed from the air by combustion in a closed chamber. The piston in a cylinder is forced into this vacuum by the normal air pressure. This occurs twice in one revolution since the cylinder lies between two closed chambers and is open at both ends. There is no compression, hence quiet running. Especially suitable for mopeds. Light construction, alternative fuels. The air slipstream is also blown through the combustion or air chamber. Double power action for one revolution.
Patent DE-3624582-A1 (DE)
Title: Ladder with stabilising means
IPC: E06C7/46
Filed: 1986-07-21
Abstract: The pivotable ladder point is releasably and fixedly connected on a thread spindle on the bottom string part of the aluminium ladder by means of a wing nut and a shell-type arresting means. If the pivotable securing point is directed upwards parallel to the strings, then, in the case of a smooth underlying surface, the rubber or plastic foot of the ladder is prevented from sliding. If the pivotable ladder point is rotated through 180 DEG , said point, in the loose, naturally growing underlying surface, ensures, by penetrating into the earth, that the ladder is secured to the greatest possible extent from slipping away, whereas, in the stated case, the rubber or plastic foot would more likely cause the ladder to slip away. A fundamental standpoint is, in addition, that, in a simple manner, virtually anyone can retrofit any ladder with this pivotable ladder point.

Title: Electrical contact terminal
Inventor: CATU JEAN-PIERRE
IPC: H01R11/15
Filed: 1986-07-30
Abstract: The invention relates to a contact terminal which is intended to produce a connection between an electrical main conductor and a branch conductor and has a fixed clamping jaw and a moving clamping jaw. According to the invention, a means is provided which simplifies its engagement between these jaws and prevents it from becoming free accidentally or assuming a divergent position with respect thereto, which divergent position is able to cause a poor contact. According to the invention, this means consists of an inclined lateral ramp which is arranged in front of the jaws and extends considerably beyond one of the side surfaces of the clamp, with which clamp said lateral ramp forms the silhouette of a hook which continues downwards at least as far as the level of the moving jaw in the completely open position. If this ramp is pressed against the main conductor by a light tension force, then its profile leads to the clamp being rotated through a quarter of a turn and the conductor automatically being guided between the jaws and preventing it from being released accidentally. <IMAGE>

Title: Telephone handset with visual display device
Inventor: HUTT HANS
IPC: H04M1/82
Filed: 1988-03-14
Abstract: In a telephone handset, a plurality of which are connected to workstations or answering stations of predominantly multi-user dealing room systems, it is intended, in the case of connections which are on hold, to be able to identify by the presence of voice frequencies that the resumption of a call is desired. Within the handset, a speech recogniser connected in parallel with the receiver has an operational amplifier with a following band-rejection filter for audio frequencies and a threshold amplifier connected to it which, via a switching amplifier, activates a visual display element provided in the handset. If a multiplicity of connections are on hold, which are switched directly to handsets, fast and simple identification is enabled of the handset whose connection is intended to be switched to call mode, because the other party to the call sends an audible signal. With audible signalling only, the handset concerned cannot be identified as readily as with visual display.
