Title: Method and apparatus for achieving precise lengths on portions obtained by shearing steel bar and billet material for use as blanks for massive forming
Inventor: VOLKSHEIMER DIETER
IPC: B23D33/10
Filed: 1984-04-14
Abstract: When bar and billet material made of steel is being sheared, the start of the billet is raised briefly from the shearing plane and transported by means of a table roller and is pressed against a counter-abutment by means of a hold-down device, whereupon the shearing stroke is initiated. During the feeding operation, the billet is pressed against the hold-down counter-abutment under a hold-down action of predetermined magnitude, the fixing of the billet being accomplished by a hold-down force of higher magnitude. The setting of the stroke limitation of the axially movable billet is coupled to the feed device which applies the necessarily constant feeding force. A fixed collet (30) which grasps the billet bar is provided for the said billet, its collet jaws (32, 33) being subject to spring action (34, 35) in the axial direction. The axially movable feeding collet (14) has an infinitely variable stroke limiting device (39) with a servo motor (40) by means of which the length of block to be sheared off can be adjusted.

Patent DE-3427226-A1 (DE)
Title: Spur-wheel gearbox
Inventor: FRANKE RUDOLF PROF DR ING
IPC: B60W30/18
Filed: 1984-07-24
Abstract: In the main application, a description is given of a spur-wheel gearbox for motor vehicles and the like, the speeds of which are selected in steps under load by means of a double clutch (2). The aim is, by reducing the number of synchronisable shifting dogs for selecting the six forward gears to considerably reduce the outlay on manufacture. This is achieved essentially by a new arrangement of the power flow in the various gears and by a particularly favourable hydraulic control of the synchronisable shifting dogs. In the flywheel (1) of the engine, the spur-wheel gearbox contains a double clutch (2) with an output shaft (16) which is not coaxial with the axis of the flywheel (1) and the two ends of which can serve to drive live axles of the vehicle. It is the object of the invention, by means of constructional measures which do not require any additional outlay, so to improve the above-described spur-wheel gearbox that both the noise of the gearbox and the internal frictional losses are reduced in the higher gears. This is achieved by virtue of the fact that a mating gear rotatably mounted on the output shaft (16) can be selectively coupled to the output shaft (16) by means of a synchronisable shifting dog (1'). <IMAGE>

Title: Conveying device for metal strips downstream of a roll stand, especially for thin hot strips
Inventor: NOE OSKAR DIPL ING
IPC: B65H23/24
Filed: 1984-08-24
Abstract: The invention relates to a conveying device for metal strips, comprising a conveying channel through which a medium flows and which has inflow nozzles for feeding in the medium which are set at an angle to the metal strip in the conveying direction. The inflow nozzles are designed as conveying nozzles and the conveying channel is designed as a circumferentially closed channel. A gaseous or liquid carrier medium is used as the medium. For the floating conveyance of the metal strip surrounded by the carrier medium, the conveying nozzles produce a flow bed with a controllable flow velocity and a controllable pressure above and below the metal strip, the selected flow velocity of the carrier medium being considerably higher than the strip velocity. In this way, it is possible to dispense with mechanical conveying means and damage-free strip conveyance is guaranteed. <IMAGE>

Title: Valve-controlled, water-cooled double swirl chamber/flow heating machine
Inventor: DREIFKE CLAUS
IPC: F24D19/10
Filed: 1985-01-22
Abstract: Because a heating generator with maximum heating capacity is an essential criterion of the CIRCO HEATING SYSTEM, but conventional heating boilers do not satisfy this requirement, the aim arose of necessity to develop a suitable heating generator. The invention works according to the "flow" system, the flames generated by a pressure forced-draught burner being guided in a swirled state over large-surface heat exchangers in specially shaped combustion chambers, and periodic heat accumulations, which are conducted off via a cooling water jacket which can be integrated into the circuit, arising as a result of valve control. This makes possible at any desired time the immediate supply of absolutely hot water into the circuit; without any compulsion for energy-consuming preparedness/keeping ready; with maximum utilisation of the waste heat and also its additional storage. Effective advantages: great energy saving as a result of optimum utility ratio between heating water production and demand. Maximum heat/outgoing air utilisation. Domestic hot water preparation without additional device. Environmentally kind design. Use of the heating machine even in all other, known heating systems. <IMAGE>

Title: Hover car
Inventor: LAMMERS ALBERT
IPC: B60V3/02
Filed: 1985-04-15
Abstract: Dying forests, exhaust gases, problems, like the analyses and suggested solutions, are never ending. Solutions must follow the laws of nature. Motorists are well aware of one of these laws of nature: the car picks up speed, the air stream moves under the vehicle and carries it - no, unfortunately not to the destination, but rather into the ditch. This law of nature can help save energy. If, for example, an invisible hand were to lift up a lorry onto a cushion of air, a child could propel this lorry, in fact even an entire goods train. This means that, if this law of nature were utilised correctly, many birds could be killed with one stone. For this purpose, the air stream would have to be prevented from leaving the underside of the vehicle at the sides since only in this way is it possible to build up a cushion of air under the car. Of course, the underside of the vehicle must also be appropriately designed, that is to say flat. However, the vehicle must not be able to veer off to the side. This is prevented in that straight side walls are lowered into grooves in the road, a portion of the air stream flows round the side walls, thanks to their design, in the grooves in order to prevent friction. Since only small drive forces are necessary, small, electrically driven, funnel-like threaded tubes which spiral a portion of the air cushion through them and under the vehicle, as a result of which the vehicle is propelled forwards, are sufficient. If, in this way, air streams are ... from the front on the right to the rear of the left and from the front on the left ... Original abstract incomplete.

Abstract: Plant for purifying industrial exhaust gases, in particular flue gases from power station boiler furnaces, using calcium compounds suspended in water, having a desulphurisation scrubbing tower with an attached demister, which is connected for washing to a fresh water line and a desulphurisation unit having a desulphurisation scrubbing liquid circulation, and a prescrubbing tower having an attached demister, which, for washing, is likewise connected to a fresh water line, and a prescrubbing unit having a prescrubbing liquid circulation, the fresh water fed to the demisters covering the fresh water consumption of the plant. The prescrubbing unit is configured solely for scrubbing out hydrochloric acid and is provided with a prescrubbing liquid having a pH of about 2. Calcium chloride formed in scrubbing out the hydrochloric acid is conducted away with the waste water from the prescrubbing liquid circulation. Calcium sulphate crystals can be introduced into the prescrubbing liquid circulation, with the off-flow from the desulphurisation scrubbing liquid circulation, in an amount such that gypsum precipitating from the scrubbing water in the prescrubbing tower during the evaporation grows on the calcium sulphate crystals. A part-stream of the off-flow from the desulphurisation scrubbing liquid circulation can be fed, together with the fresh water, to the demisters for washing. <IMAGE>

Title: Process and converter for the production of steel
Inventor: BOGDANDY LUDWIG VON PROF DR
IPC: C21C5/34
Filed: 1985-08-31
Abstract: In a three-phase process and converter for the production of steel, the scrap is preheated by means of converter exhaust gas in a charging vessel provided with a bottom gate and having a bottom opening corresponding to that of the converter, preheated scrap is simultaneously melted in the converter and the melt is then refined and converter exhaust gas is fed back to the converter as combustion gas. The converter has an arched bottom and a cylindrical casing with a ratio of diameter to height of from 1.4 to 1.8. This gives a compact converter which allows the charging of large quantities of scrap, even loosely packed and bulky scrap, and, in the case of the arrangement of tuyère in the lower part of the converter, rapid melting down of the scrap with the aid of combustion gases but also refinement of the melt by the blowing in of oxygen below the surface of the molten metal.

Title: Method of producing dental prosthetic bridges from individual bridge members
Inventor: KOERBER KARLHEINZ PROF DR
IPC: A61C13/003
Filed: 1985-10-17
Abstract: The invention relates to a method of producing dental prosthetic bridges from individual bridge members in which the individual teeth, groups of teeth and bridge members arranged so as to fit exactly on the working model are soldered to one another directly on the model - of an incombustible material - to give the finished part. Heating of the soldering gap region to the operating temperature is effected via a high-energy heat source so quickly that the soldering operation is concluded within a few seconds, so that any significant heating of the working model is avoided. This method makes it possible to omit the previously necessary, multi-stage soldering operation: fixing on the working model, removal of the block, embedding, where appropriate, in a soldering composition and subsequent soldering, and due to the lack of intermediate steps it ensures a significant increase in the fitting accuracy of the dental prosthetic bridge and quicker production.

Inventor: PIETSCH GUENTER
IPC: B01J13/18
Filed: 1985-12-23
Abstract: A process is described for micro-encapsultion of hydrophobic oils containing dissolved colour reactants of colour reaction systems by reacting a water-soluble non-ionogenic melamine-formaldehyde precondensate and a water-soluble polymer in an oil-in-water dispersion to form the capsule sheath. The particular characteristic of this process consists in the oil-in-water dispersion being stabilised by mixing, with vigorous stirring, an aqueous solution of a cation-active melamine-formaldehyde precondensate and the aqueous solution of a water-soluble polymer, a solid precipitating in the mixture as a very fine suspension, the mixture thus obtained having very fine solids suspended therein being mixed, with vigorous stirring, with the oil containing the colour reactant in solution, acidifying the oil-in-water dispersion thus obtained and adding, with stirring, an aqueous solution of a water-soluble non-ionogenic melamine-formaldehyde precondensate to form the capsule sheath. Employing the cation-active melamine-formaldehyde precondensate produces precipitation of a very fine, suspended reaction product thereof which results in stabilisation of all the reaction systems in the course of the process. Excellent capsules without agglomeration can be obtained. The invention further relates to the microcapsules obtainable according to the above process and ... Original abstract incomplete.
