Title: Soundless door closing device for motor vehicles
Inventor: THREIMER CHRISTIAN
IPC: E05B81/20
Filed: 1987-01-22
Abstract: Since there have been motor vehicles in the world, the doors have simply been slammed shut for closing. The associated noise has meanwhile become a great environmental nuisance. This environmental nuisance is completely excluded by means of an electromagnetic door closing device. By gentle pressure of the vehicle door, a rotary magnet fastened in the vehicle frame is made to carry out a half rotation and thus a door bolt mounted on the door is attracted to the fixed door closing position. In the event of undesirable slamming of the door, the door closing process is blocked, i.e. the door must again be pressed gently. Opening the door takes place in the conventional manner.

Filed: 1987-02-24
Abstract: The nozzle assembly of an electrostatic spray gun has an adapter which is made of an electrically insulating material and has a front surface facing in the direction of propagation of material issuing from the orifice of the nozzle. The adapter has a frustoconical extension which surrounds the orifice and whose external surface defines with the front surface of the adapter an annular space for the tips of electrodes which ionize air flowing toward the spray of material that issues from the orifice. The locations of the tips of electrodes (preferably very close to the front surface of the adapter) and the inclination of the external surface of the frustoconical extension determine the location of contact of ionized air with the spray. The tips of the electrodes are shielded from mechanical damage by being located in the annular space.

Title: Roadway conveyor with spill plates, guide rails and shifting device
Inventor: MOHRMANN MICHAEL DIPL ING
IPC: E21D23/08
Filed: 1988-08-09
Abstract: The operation of roadway conveyors (1) for conveying coal in mines is often unsatisfactory today because the transfer conditions between the drive or transfer station (26) of the face conveyor (32) and the roadway conveyor (1) are disturbed by horizontal displacement of the face conveyor (32) following the advance on the one hand and by heaving of the roadway floor (60) and associated vertical displacement of the roadway conveyor (1) on the other hand. In addition, the known technical solutions for shifting the drive station (26) or an accompanying fine-coal conveyor (36) are inadequate on account of impairment by excavated material and/or awkward operation. According to the invention, therefore, guide rails (6) are proposed for the roadway conveyor (1). Via sliding pieces (10) or sliding claws (29), the guide rails (6) permit the use of a novel shifting device (35) as well as links (28) for the shifting or parallel guidance, for example, of the drive station (26) of the face conveyor (32). At the same time, a novel clearing device (45) for clearing the roadway floor (60) under the roadway conveyor (1) is presented.
