Title: Static heat recuperator for lime-burning rotary kilns
Inventor: SAMMARTIN LIONELLO
IPC: F27B7/20
Filed: 1983-03-31
Abstract: Heat recuperator for use as a preheater of the limestone in lime-burning rotary kilns, the installation being divided into a number of modular elements (one to ten), of which each consists of a shaft-like housing (14) in which the gas stream leaving the rotary kiln and the descending stream of solids (limestone) are divided up; regulating elements (11, 12 and 13), which can be actuated from outside, are provided for the rate of gas, and also control elements (15), which likewise can be actuated from outside during the operation of the installation, for the quantity of limestone taken out of the modules, and also preceding devices (1, 2) are provided for transporting the limestone, connected to regulating devices on subsequent receiving and distributing devices (3,7,9) which are equipped with flaps (4 and 5) and level indicators (6,8), with the possibility of shutting down a module in order to carry out repair work, without switching off the installation. <IMAGE>
Patent DE-3312108-A1 (DE)
Title: Device for electronic control of the actuation of an actuating element
Inventor: DILLMANN GERHARD
IPC: H02M3/156
Filed: 1983-04-02
Abstract: A device for the electronic control of the actuation of an actuating element (12) by means of an intermittent control current is proposed, a DC voltage which is supplied to a comparator (13) being present as the control signal. A voltage which is dependent on the control current is supplied to a second input of the comparator (13). The comparator output controls an electronic switching element in the circuit of the actuating element (12), via a time delay element (14 to 17). In this way, an intermittent control current having an essentially constant duty cycle is generated, the current which is set in each case being a function of the control signal. In this way, good linearity between the desired and actual values can be achieved, as well as independence of the inductance of the actuating element. Furthermore, a simple and cost-effective implementation, as well as simple driving via a microcomputer output, can take place. <IMAGE>

Patent DE-3322185-A1 (DE)
Title: Device for converting translational motion into rotary motion, preferably in reciprocating-piston engines
Inventor: NEUMANN ULRICH DR ING
IPC: F02B75/02
Filed: 1983-06-21
Abstract: Nowadays, reciprocating-piston engines make up 15 to 25 % of the unladen weight of vehicles. The weight of the engine is reduced by the conversion of translational motion into rotary motion in a small overall space and by keeping the oscillating weights small. The piston skirt has a sinusoidal boundary and operates against pivotable pins. The piston and the pins are held in continuous contact by spring force. Air under pressure from a pressure-charging device assists the piston movement opposed to the power stroke and improves fuel consumption. The addition of oil to the fuel is superfluous in a two-stroke variant of the engine, which has a rotating piston which slides on an air cushion between the cylinder wall and the piston skirt.

Title: Headlight for motor vehicles
Inventor: ILG KARL HEINZ DIPL ING
IPC: B60Q1/105
Filed: 1983-09-21
Abstract: The automatic beam width control of the headlight has on the two axes (11, 12) an inductive signal generator (15) whose signals, which correspond to the spring deflection of the vehicle body, are fed to a control arrangement which is formed either by an electronic switching device (52) with a solenoid valve (53) or an electric adjustment motor (32) with a pressure controller (33). The control arrangement generates a pulse which connects a pneumatic adjustment motor (29) of each partial headlight (21) to a partial vacuum source (28). By means of the three working positions of the control arrangement, the reflector (23), which is coupled to the pneumatic adjustment motor (29), is moved in relation to the carriageway (14) and the inclination of the dipped beam is kept constant for different degrees of loading of the vehicle body. <IMAGE>
Patent DE-3336350-A1 (DE)
Title: Yarn-tension indicator
Inventor: ZWICKER KURT
IPC: G01L5/06
Filed: 1983-10-06
Abstract: With this yarn-tension indicator for continuously measuring the yarn tension during the winding of strands, impregnated with laminating resin, of a reinforcing material consisting preferably of glass-fibre or carbon-fibre rovings or yarns, the object is to make it possible to read off the yarn tension continuously during the working operation and at the same time compensate unequal draw-off forces, such as can occur during the unrolling of the reinforcing material from the bobbins. For this, there are three guide elements which are arranged at the corner points of an imaginary triangle in such a way that a winding strand, which comes from an impregnating bath and is impregnated with laminating resin and the run-off of which is inhibited by an adjustable tensioning device, can be guided under the first guide element and beyond the second guide element to the third guide element, the second guide element being vertically displaceable counter to the force of a spring, and this displacement being measurable.

Title: Process for obtaining hydrocarbons, liquid under normal conditions, from a carbonaceous feed material
Inventor: WILHELM ACHIM DR ING
IPC: C10G1/04
Filed: 1983-12-16
Abstract: In a process for thermal upgrading (pyrolysis) of a carbonaceous feed material such as, for example, coal, oil sand or oil shale, it is proposed to carry out the reactions in an atmosphere of aromatic hydrocarbon vapours such as, for example, toluene or BTX aromatics produced in the process itself. In this way, the yield of hydrocarbons liquid in the normal state is increased considerably. Furthermore, because of the substantially improved ignition and reaction properties of the semi-coke obtained, the process is suitable as an upstream process for power stations or coal gasification plants.

Title: Automatic bread roll moulding and cutting machine for producing genuine split bread rolls for artisanal enterprises
Inventor: KOEVY SANDOR
IPC: A21C3/06
Filed: 1984-01-18
Abstract: The production of split bread rolls is still carried out by hand, that is the bread roll dough piece is first taken up by a worker, made to length and laid into the fermentation basket. After a short fermentation time, the dough piece is held by one hand and cut using the other to about half the depth or deeper, then taken up again and turned over so that the bread roll lies with the cut surface facing downwards and only after this is it given the final proof. This method is highly laborious and time-consuming. The invention has created a solution which makes the described handling completely unnecessary. The bread rolls can be produced easily, completely automatically and rapidly.
Patent DE-3402584-A1 (DE)
Title: Hydraulic synchronous control system
Inventor: BLOCK SIEGMAR
IPC: E21D23/16
Filed: 1984-01-26
Abstract: To achieve synchronism between a walking cylinder 1 and sliding cylinders 11, 11', 11'' which serve to displace a forepoling cap, a differential pressure valve 19 is provided which is opened via a control line 25 if the pressure in the connecting line 8 between the walking cylinder 1 and the sliding cylinders 11, 11', 11'' exceeds a certain value. After opening of the differential pressure valve 19, the piston rods 14 of the sliding cylinders 11, 11', 11'' and thus the forepoling cap are moved. The pressure in the connecting line 8 drops due to the movement of the piston rods 14, so that the piston rods 14 are prevented from moving further by the closing of the differential pressure valve 19. Therefore the piston rods 14 move intermittently in synchronism with the piston rod 5 of the walking cylinder 1. When the sliding cylinders 11, 11', 11'' are blocked, the pressure at the control connection 24 of an anti-blocking valve 23 mechanically coupled to the differential pressure valve 19 rises, so that, after opening of the anti-blocking valve 23, the pressure in the connecting line 8 between the piston space 3 of the walking cylinder 1 and the piston spaces 10 of the sliding cylinders 11, 11', 11'' can be reduced. The walking cylinder 1 can then further displace the face conveyor 7 unhindered, because the function of the differential pressure valve 19 has passed to the anti-blocking valve 23. <IMAGE>

Title: Method for producing heat pipes for an electrical ignition device
Inventor: BENEDIKT WALTER
IPC: H01T13/16
Filed: 1984-08-09
Abstract: For the purpose of producing heat pipes (5) which contain sealed cavities, capillaries (16) and an evaporatable medium and are intended in particular for ignition chambers of ignition devices, it is proposed to proceed from a straight pipe into which the medium is introduced in the form of a section of, for example, metallic wire. The pipe is sealed at both ends to form a heat pipe (5) by fitting crimp fasteners (19). The heat pipe (5) is bent, for example, in a meandering fashion in such a way that turns which are produced bear against one another and in this way form a wall-like component. The turns can be soldered together. Before the introduction of the evaporatable medium, the pipe is constricted once or several times in the cold state, thus producing in it compressive wrinkles with a capillary action. <IMAGE>
Patent DE-3433729-A1 (DE)
Title: Tool for machining metallic and non-metallic materials
Inventor: DIETRICH RAINER DR
IPC: B24D5/12
Filed: 1984-09-14
Abstract: Tools which are used in the machining of non-metallic materials, in particular stone, are subjected not only to the wear caused by the actual operation of machining the stone on their active machining edges and faces but likewise to wear on the passive tool flanks and sides which are not in contact with the stone but are exposed only to the flow of cooling lubricant. This wear of the passive tool flanks, which is based on erosion, cavitation and corrosion effects and considerably reduces the service lives of expensive machining tools is to be eliminated. It is therefore proposed to form the wear-protecting layer at least partially surrounding the basic tool body of such a tool from a soft composite material, so that the adverse effect of the processes causing the abrasion or wear is eliminated by energy absorption or particle reflection. <IMAGE>
