Title: Method and device for producing strips and wads of bags
Inventor: SCHERZ WILHELM
IPC: B31B50/64
Filed: 1982-03-16
Abstract: A machine for producing strips or wads of bags, setting out from two continuous film webs (18, 22) guided one above the other, comprises a welding station (12), a collecting station (14) and a belt conveyor (28) for moving the film webs through the welding station and to the collecting station. The welding station (12) contains a welding head (42) which heats the film webs at a given point in time in a welding region having only small dimensions. The welding head can be moved transversely to the film conveying direction by a drive (40) which is mechanically disconnected from the drive (30) of the belt conveyor (28). In the production of continuous strips of bags, the collecting station is a winding station. In the production of wads of bags, the collecting station (14) has various drives (50, 58, 64, 68) for tearing off and gathering portions of strips of bags to form piles, which drives are mechanically disconnected from the drive (30) of the belt conveyor (28) and serve for moving different gripping tools (54, 60) and a collecting table (52). A synchronisation of the different drives which is suitable in each case for a particular bag format takes place by a computer (80) to which there is assigned an input unit (84) for bag format data and other operating parameters, such as the film conveying speed and the welding temperature. <IMAGE>

Title: Articulated corner for shutterings
Inventor: SCHLIEPHACKE HEINRICH DIPL ING
IPC: E04G17/00
Filed: 1982-03-31
Abstract: The invention relates to an articulated corner for shutterings, in which two angles are connected to one another in a manner of a hinge, and further shuttering elements can be joined to their protruding free legs. The dead angle, customary in such constructions due to the hinge, is eliminated according to the invention by the fact that the two legs connected to one another in articulated manner are also provided with adjoining possibilities for shuttering elements. In this way, it is possible, as is known, to join shuttering elements to the free legs in the normal angle region, and to join the shuttering elements to the other legs of the articulated corner in the hitherto dead angle region. As a result, any desired angles from 0 DEG  to 360 DEG  can be formed.

Patent DE-3219568-A1 (DE)
Title: Grinding and polishing body
Inventor: AUGUSTIN RAINER
IPC: B24D3/00
Filed: 1982-05-25
Abstract: A grinding and/or polishing body is constructed in such a way that at least two types of solid particles are distributed over its thickness as grinding and/or polishing agents inside a binding agent in such a way that the centres of gravity of the distributed densities of the two types of solid particles do not correspond. The solid particles of the two grinding and/or polishing agents consequently come into action one after the other during the grinding or polishing, as a result of which, for example, first a coarse finish and then a fine finish with continuous transition can be achieved. These distributed densities inside the grinding and polishing body are obtained by the relevant mixture being centrifuged in suitable moulding containers so that, in accordance with the different density of the solid particles used, segregation and thus preferably localization of the two grinding and/or polishing agents results in the area of the one or the other surface of the polishing body. This segregation, i.e. the spacing of the centres of gravity of the distributed densities of the two types of solid particles, can also be controlled by the one type of solid particle (for example grinding agent) being added in agglomerated form to the total mixture, in which case an auxiliary agent having a low specific density, for example cork dust, serves as backing core which is encased by the relevant grinding or polishing agent. By alternative agglomeration on the one hand and selection of the mixture constituents and the centrifuging conditions on the other hand, grinding and polishing bodies can be produced which can be set in an optimum manner to the surface character of the workpiece to be machined.

Title: Method for regulating a resistive load having a temperature coefficient, and a circuit for carrying out the method
Inventor: KUNTZ EDUARD ING GRAD
IPC: G05D23/24
Filed: 1982-08-30
Abstract: A method for regulating a resistive load having a temperature coefficient, by means of a semiconductor-switch power actuator in the supply circuit of the resistive load, which actuator is switched periodically by means of control pulses, in accordance with the clock principle, the switch-time duration of the actuator being variable as a function of a regulator which controls the temperature of the resistive load according to the resistance value. The actual resistance value which is to be detected for the temperature measurement by means of the regulator (3), by comparing the current in the resistive load (H) with the voltage dropped across it or with the supply voltage, is determined by switching-on the actuator (st), initially briefly in each case, enforced by means of a clock transmitter (5) whose clock pulses (I) are supplied by a decoupling diode (6) to a comparator, which carries out the comparison, of the regulator, and, if the resistance value is less than a predetermined value, it is held switched-on until the resistance value is greater than the predetermined value. <IMAGE>

Title: Rotary combustion engine
Inventor: LEIPZIGER WERNER
IPC: F01C1/344
Filed: 1982-10-23
Abstract: Rotary combustion engine consisting of a casing with an oval internal wall and a circular flywheel which is secured on a shaft or spindle and is provided with blades which slide in a double guide of the casing, which guide imparts the oval revolution to the blades. The chambers, which become smaller or larger during the rotation of the flywheel, are formed in the free oval space of the casing between the blades. There can be any desired number of chambers, depending on the number of blades. Two spark plugs are provided and there are thus two ignitions per chamber for each revolution of the flywheel. This gives a high engine power. The fresh air/gas mixture is fed to the chambers formed in the oval space of the casing between the blades via two inlet ports and the exhaust gases escape via two outlets of the casing. By virtue of its central position, the shaft or spindle is vibration-free. As a result, it is also possible to arrange a plurality of units in the same location, the timing of the ignition sequence varying as in multi-cylinder engines.
