Title: Coding device for spark ignition engines of motor vehicles
Inventor: OBERHAUS HERBERT DIPL ING
IPC: F02P5/152
Filed: 1987-08-07
Abstract: A coding device for spark ignition engines of motor vehicles with a plurality of ignition performance characteristics matched to a certain type of fuel (octane rating) serves for activation of the ignition performance characteristic assigned to the respective fuel used. For this purpose it has a connector housing, connected by a cable loop to an ignition control module, and a connector, interacting with the said housing and making the electrical connection to the ignition control module. In the connector, two different electrical resistors, each respectively assigned to a partial current circuit with connector contacts, are arranged, a first partial current circuit with a first resistor serving for the activation of a first ignition performance characteristic and a second partial current circuit with a second resistor for the activation of a second ignition performance characteristic. On the connector housing, a stop is provided and, on the connector, a counter-stop for just two defined connector positions on the connector housing, in such a way that the partial current circuit of the cable loop open on the connector housing can be closed in a first connector position by the first partial current circuit of the connector and in a second connector position by the second partial current circuit of the connector. Such a coding device can also be used for the coding of a speed limit and/or a fuel-air mixture adjustment and/or an adjustment of the idling speed. The advantage of this versatility of the coding device in question comes ... Original abstract incomplete.
Patent DE-3728334-A1 (DE)
Inventor: DALLA TORRE HANS DR PHIL
IPC: C08L77/06
Filed: 1987-08-25
Abstract: A thermoplastic mouldable, impact-resistant, polyamide alloy comprises   (a) at least 98% by weight of an amorphous copolyamide derived from an optionally alkyl-substituted hexamethylenediamine, a bis(4-aminocyclohexyl) C1-4 alkane substituted adjacent to the amino groups, and a dicarboxylic acid, and   (b) up to 80% by weight of a modified copolyolefine.   Moulded bodies obtained from such alloys exhibit high rigidity with outstanding impact resistance over a broad range of temperature, very low water uptake, very high dimensional stability and low permeability to oxygen as well as high shape retention on heating and, on account of their relatively low melt viscosity, are very suitable for processing in injection moulding and extrusion procedures, particularly for the preparation of e.g. thin-walled or large surface area parts such as claddings, films, etc.

Title: Steel production process and system for carrying it out
Inventor: LANGHAMMER HANS JUERGEN DR ING
IPC: C21C5/56
Filed: 1987-09-30
Abstract: The invention relates to a steel production process for smelting scrap, sponge iron pellets in prereduced form or the like, and optionally corresponding crude metals (bullion), in a stationary smelting vessel, the continuously smelted starting materials being fed to a heated continuous-treatment vessel in which separation of slag takes place continuously, the material present in the continuous-treatment vessel is superheated and, by the addition of appropriate alloy and deoxidation additions, the desired steel composition is achieved. In order to ensure in a direct way the continuity of the direct steel production up to continuous casting, without having to collect the steel in the meantime or decanting it elsewhere, it is proposed that, by selecting the oxidising smelting conditions and the carbon content in the starting material, carbon contents between 0.002 and 0.01 % in the metal are set in the continuous-treatment vessel (6), and that the liquefied material (3) flows into a first chamber (6') of the continuous-treatment vessel (6) fitted out as a tundish, where it is slagged off (deslagged) and the slagged-off metal flows into a second chamber (6'') of the continuous-treatment vessel (6) where it is alloyed, deoxidised, superheated and mixed through and, from the second chamber (6'') is continuously cast into a continuous-casting mould (18). <IMAGE>

Patent DE-3735050-A1 (DE)
Inventor: KOERNER JUERGEN DIPL ING
IPC: B65B51/00
Filed: 1987-10-16
Abstract: Producing the feed movement of the rotary grippers in accordance with shortening of the wrapping material during the twisting process is in the prior art solutions resolved by exchanging the cam members or by interposition of a crank transmission, at quite considerable cost. The problem on which the invention is based resides in achieving a rapid feed of the rotary grippers by adapting to the actual progress of the shortening of the wrapping material at the commencement of the twisting phase and of rendering the magnitude of the feed movement adjustable by simple means. The problem is resolved in that during one working phase the rotating gripper 9 always performs the maximum stroke and the feed movement, related to the opening and closing movement of the rotating gripper in the working diagram, is adjustably displaceable so that different portions of the stroke (A-B) become effective for the twisting process. The reciprocation of the gripper 9 carried on a rotating sleeve 6 is effected by a cam 3 on drive shaft 2 effecting swinging of a pivoted lever 4. The opening movement of the grippers as effected by relative reciprocation of a rack 10 by means of a lever 15 coacting with a cam 12 on which lever 4 is mounted. Cam 3 is rotatably adjustable about shaft 3 via pin and slot coupled discs 24 and 25 so that selected portions of the stroke during twisting of the wrapper are effective - i.e. the proportion of the stroke effected with the gripper closed can be selectively varied. <IMAGE>

Title: High-voltage test transformer having insulated core segments
Inventor: SOMMER BERND DIPL ING
IPC: H01F38/18
Filed: 1988-02-09
Abstract: A single-phase high-voltage test transformer for mains frequency, core type in insulating-sheath or dry-type construction with elongated core divided into insulated segments and leakage suppression windings arranged in cascade formation in economiser circuit which resemble the high-voltage windings (linear cascade). In the case of test transformers with MV and MVA orders of magnitude, a technical and technological advantage arises, in comparison with a cascaded testing transformer, through the linear voltage build-up from the base to the head of the transformer and compact construction comprising many stacked identical components, which outweighs the disadvantage of the outlay on winding and core which is necessary for adequate coupling. Test transformers with kV and kVA orders of magnitude may, as dry-type transformers in kit-construction form, consist of convenient components which are stacked according to the requirements of the testing operation.

Abstract: A shaft-sealing system for sealing off rotating shafts with alternating and at times high speeds of revolution and alternating and at times high pressure loading by the sealing medium consists of two lip-sealing rings arranged axially in series and of a supporting ring arranged between them. The outer air-side lip-sealing ring forms a protection ring against the penetration of dust from outside while the inner lip-sealing ring provides a seal relative to the sealing medium as the actual sealing ring, the axial limb of the supporting ring forming a support which protects the sealing lip of the inner lip-sealing ring from a deformation due to high pressure loading. The housing ring of the outer lip-sealing ring at the same time forms a stepped cylindrical receptacle into which the supporting ring and the inner lip-sealing ring are inserted with a press fit to form a centred, rotationally coupled installation unit. <IMAGE>
