Patent DE-3715620-A1 (DE)
Title: Device for removing floor coverings
Inventor: WITTE MICHAEL
IPC: E04G23/00
Filed: 1987-05-11
Abstract: In a known device for the aforementioned purpose, a cutting knife is made to vibrate by means of an electric right angle grinder. The process of replacing the series-produced driveshaft of the right angled grinder with a new shaft with an eccentric outer shaft end is disadvantageous. The new device is intended to make this awkward conversion procedure unnecessary. The new device is characterised by a rotary body (4) having an eccentric reception aperture (41) for a driveshaft (23) of the drive motor (2) and by a cutting knife holding body (5) which at least partly encloses the rotary body (4), permits rotation of the rotary body (4) and is mounted on the outside (42) of the latter. In this device, the existing driveshaft of the right angle grinder is advantageously also used as a power source. The device is especially well suited for peeling off floor coverings, especially carpets which are bonded to their base. <IMAGE>

Title: Rotary multiple-piston flywheel engine
Inventor: KERL WERNER
IPC: F02B53/00
Filed: 1987-05-30
Abstract: The spark-ignition internal combustion engines manufactured at present still give rise to severe environmental pollution, are complex and expensive and can be improved in terms of power and energy only slowly and in small steps. The new rotary multiple-piston flywheel engine is intended to be less harmful to the environment, of simpler construction, simpler to maintain, to consume less energy and be less expensive. Because inertia forces and moments do not occur, the following parts are eliminated: counterweights, a camshaft, intake and exhaust valves, a crankshaft, connecting rods etc., and, as a result, the engine is simpler in construction and the cost of manufacture is reduced rapidly. The intake and compression, ignition and expansion, exhaust and lubrication phases are assigned their own independent working chambers. Fuel is saved by the possibility of optimum compression setting (volume alteration) and any expansion pressure which is not used by one ignited chamber can be passed to a following unignited piston. During all ignition processes, the ignition torque is further assisted by the mass of the flywheel. Because of the many possibilities for saving fuel and inexpensive manufacture the rotary multiple-piston flywheel engine is suitable wherever internal combustion engines are currently being used. <IMAGE>

Patent DE-3720685-A1 (DE)
Title: Method for improving the reaction in combustion chambers and secondary reaction areas in the case of burners operated with solid and liquid fuels
Inventor: LEISTRITZ HANS KARL DR
IPC: F02B75/02
Filed: 1987-06-23
Abstract: The main Application P 3714831.1, to which this additional application represents a further improvement, developed a new charging characteristic for the heat engine operating as a piston engine. Since, at high engine speeds, the expulsion of exhaust gas attains the same degree of continuity as that of continuously operating furnace (firing) burners, the knowledge gained with this method is partially transferrable to furnace burners. The multi-phase transformation system, developed in the main application, of a conduit section has been improved by various means as regards the combustion process which follows the first mixture formation stage in firing systems operated with solid and liquid fuels. The conduit section is provided with dead-space-free concentrated flow with the formation of a focus in accordance with a divergence/convergence mixing system, and the axially positioned focus undergoes a swirl-like downstream widening by rotary impulses and this not only increases the quality of mixing but also the heat transfer to hearth surfaces and for other firing purposes. By these means, the impermissibly high excess of air in furnace burners can be lowered and the process removal of nitric oxides is easier to control.

Patent DE-3731762-A1 (DE)
Title: Method for controlling or limiting the temperature in induction heating coils, in particular for household induction cooking appliances, and a device for carrying out the method
Inventor: GEHRKE BERND DIPL ING
IPC: H05B6/12
Filed: 1987-09-22
Abstract: The temperatures of induction heating coils are controlled by means of thermistors which are arranged on the bottom side of the hob and which, for their part, control a detector circuit which then interrupts the heating circuit. In this case, the temperature is measured only selectively. The novel method detects the temperatures of the induction heating coils integrally over the surface and controls them without the use of sensors. Ferrite cores (4) are radially arranged below the induction coil (5) on a coil support plate (3) of aluminium. These ferrite cores (4) focus the magnetic flux generated by the invertor. When the so-called Curie point is reached the ferrite cores (4) lose their magnetic conductivity. As a result, the magnetic field of the induction coil (5) is no longer influenced and the magnetic lines of force scatter. As a result, the power consumption drops to a quarter of the rated value and the temperatures on the induction coil (5) drop. The method can be used in household induction cooking appliances and in other, inductive heat-generating devices. <IMAGE>

Patent DE-3817126-A1 (DE)
Inventor: HULTSCH GUENTHER
IPC: B04B15/08
Filed: 1988-05-19
Abstract: Filter centrifuges for the separation of suspensions, the drum of which has a corotating syphon device according to DPS 22 60 461, have the disadvantage that the filtration-accelerating action of the syphon device is destroyed by gas intrusions into the collecting space under the filter medium. Until now, this gas could only be expelled after each charge by backwashing through the filter medium once the solid had been removed. 
<??>The object consists in providing an outlet which permits the expulsion during filtration of gases which have penetrated the syphon space. 
<??>This object is achieved by means of a non-return valve (18) radially arranged within the syphon device, preferably on the drum floor and connected to the collecting space (11) or by an additional syphon device (17, 19, 20, 21) acting as non-return valve. 
<??>This device can be used on discontinuously operating filter centrifuges with rotation syphoning according to DPS 22 60 461, the housing inner space of which is at ambient pressure or is fed with compressed gas for the purpose of further accelerating the filtration.
