Title: Process for producing an organic semiconductor
Inventor: KUTSCH HORST DR RER NAT
IPC: C09K19/02
Filed: 1986-07-25
Abstract: Organic semiconductors are solids based on crystals or polymers. Their production is comparatively expensive and often not sufficiently reproducible. The object of the novel method is to produce an organic semiconductor which is metal-free, does not need doping, can be produced from cheap, generally available starting materials and is independent of form. A liquid mixture of any desired concentration is produced at room temperature and in an inert gas atmosphere - omission from anhydrous dimethyl sulfoxide, which acts simultaneously as reactant and solvent, and a dry p-benzoquinone which is polysubstituted by halogen, cyano or combinations of the two. The mixture is slowly heated to approximately 76 DEG C in the dark, the liquid is kept for at least 6 to 8 hours at the final temperature to within +/-0.1 DEG C, and the liquid product is slowly cooled to room temperature and finally filtered hydrophobically through a very fine filter. Organic semiconductors having a liquid-crystal aggregate state and semiconductor properties at room temperature in the range up to 0.3.10<-2> OMEGA <-1>cm<-1>.

Patent DE-3629247-A1 (DE)
Title: Mechanism for converting an oscillating motion into a motion of rotation or revolution
Inventor: INGELHEIM GRAF VON
IPC: F02B1/04
Filed: 1986-08-28
Abstract: The mechanism according to the invention is used to transmit power from an oscillating part (20) to a rotating wheel (31). This is achieved with the aid of elements (29, 30) which are fixed on an oscillating body (27, 28) and, when this body is moved in one direction, produce a power flow by frictional or positive engagement and, when the body is moved in the opposite direction, disengage in such a way that ideally there is no contact between the oscillating element and the rotating wheel for the whole of the motion in the opposite direction. The mechanism can be designed in such a way that, for a given oscillation length of the part (20), the oscillation length of the elements (29, 30) varies continuously thus making it possible to construct a continuously variable positive mechanism. <IMAGE>

Title: Process for reducing the iron content of zinc melts
Inventor: SOLMS JUERGEN DIPL ING
IPC: C22B19/32
Filed: 1987-10-09
Abstract: On exceeding the saturation limit of zinc melts for iron there occurs separation of solid iron-zinc crystals, the so-called hard zinc, which sinks to the bottom of the tank and has to be removed from time to time to maintain the maximum immersion depth of a galvanising tank and to protect the material being galvanised from contamination by the hard zinc crystals. The hard zinc formation causes considerable process problems in galvanising operations, such as high consumption of zinc, quality defects in the galvanised material, cleaning expense, etc. Treating the melt with silicon reduces the iron content of the melt to below the saturation content through the formation of an iron-silicon compound which floats on the melt and thus avoids the formation of hard zinc. The process likewise enables the iron to be removed from liquid hard zinc to recover zinc.

Title: Setting brick and checkers for regenerators produced therefrom
Inventor: BALTZER FRANZ
IPC: F27D1/04
Filed: 1988-01-28
Abstract: A setting brick of refractory material is intended for checkers of regenerators in industrial furnaces and has a cross- or ring-shaped cross-section. The top face is preferably offset parallel in at least one lateral direction with respect to the bottom face, so that the setting brick is configured oblickely in this lateral direction. The offset of the top face with respect to the bottom face is of such a degree that the projection of the centre of gravity of the setting brick lies in the bottom face. The top face can be inclined relative to the bottom face. To produce checker layers, the oblique setting bricks are set one upon the other with the same or alternately directed obliquity, alone or in combination with straight setting bricks. The oblique setting bricks are suitable for drawing the checker of the regenerator into the connecting channel to the industrial furnace, in which case the openings of the checker are inclined towards the media flow. <IMAGE>

Title: Method for identifying the call type of external lines connected to multi-user dealing room systems
Inventor: HUTT HANS-ULRICH
IPC: H04M3/62
Filed: 1988-03-04
Abstract: On workstations or answering stations of switching systems, in particular multi-user dealing room systems, calls are signalled using a uniform system. Due to the special features associated with the operation of multi-user dealing room systems, different call signalling facilities are intended to be identified and implemented on a line-individual basis. By means of a specific operating procedure involving a keyboard, a line number, a line designation and a call identifier can be shown on a display. The information to be entered therewith is stored in a main memory of the switching system and is read out and decoded when an incoming call is received. The resulting commands cause, for example, a call to be displayed visually only, visually and audibly, or not at all. The method for identifying the call type of external lines connected to multi-user dealing room systems serves to create differentiating features, whereby increased user-friendliness is achieved and attention can be drawn to specific calls.

Title: Electronic change-over switch
Inventor: SCHULZE WOLFGANG
IPC: H03K17/62
Filed: 1988-04-22
Abstract: Differential amplifiers can be switched on and off by an inhibiting transistor inserted in the emitter circuit. It is the object of the invention to construct a switch of this type which makes it possible to switch over a plurality of channels. Three differential amplifier stages (A1, B1, C1) are provided, of which, however, in each case only one is optionally switched on via the associated inhibiting transistor (Q310 to Q312). An interlocking arrangement ensures that a changing combination of the control signals supplied via only two control inputs and coming from a control circuit causes the switch-over of the inhibiting transistors (Q310 to Q312). The control signals can vary between two levels. The invention can be used in instrumentation, particularly in multimeters and oscilloscopes. <IMAGE>

Title: Device for damping noises and/or pressure surges (impulses, sudden pressure changes) in a liquid
Inventor: OBERDOERFER HANS
IPC: F16L55/045
Filed: 1988-05-13
Abstract: A device for damping noises and/or pressure surges in a liquid, which is intended in particular for sanitary installations, comprises a plurality of diaphragms which jointly enclose a standard air volume in a housing. Each of these diaphragms forms an oscillating system with the air volume common to all the diaphragms. However, the resonant frequencies of all the individual systems are different due to a different choice of the frequency-determining parameters manifested on the diaphragms. The entire device is installed in a liquid path in such a way that all the diaphragms can receive an incident flow of the liquid. This device damps noises in a particularly broadband fashion and can also be used to damp pressure surges ("water surges") (Figure 1). <IMAGE>
