Patent DE-3504273-A1 (DE)
Title: Door lock
Inventor: CESTARO VOLKER DIPL ING
IPC: E05B47/04
Filed: 1985-02-08
Abstract: The subject of the invention is a door lock with a key-actuable bolt (2) which can be moved into a closing position and an opening position. Via a non-positive connection which can be cancelled as a result of the rotation of a suitable key inserted into the door lock, the bolt (2) is connected to a motor (29) which is fed by an energy accumulator (30) if the energy supply at least on the respective door fails. The motor (29) thereby moves the bolt (2) into an end position via the connection. The energy accumulator (30) is a chargeable battery which, when the motor (29) is switched off, receives from a charger (31) a uniform constant charging current flowing via the coil (42) of a relay (43). A normally closed contact of the relay (43) is connected to a monitoring circuit (54). <IMAGE>

Title: Device for the connection of a refrigeration unit to a heat recovery installation
Inventor: HAKEMANN WILHELM
IPC: F24D17/02
Filed: 1985-04-10
Abstract: The invention relates to a device for the connection of a refrigeration unit to a heat recovery installation using a thermostat-controlled three-way valve. As a result, it is possible that the condenser of the refrigeration unit is taken out of operation completely, provided the heat recovery installation can absorb the condensation heat without residue. On the other hand, the condenser is automatically called upon continuously to a greater or lesser extent for carrying off any excess condensation heat, as soon as an adjustable temperature limit is exceeded at the detector points. As a result, it is guaranteed at all times that the cooling operation is maintained without any disadvantageous influence by the heat recovery installation and the refrigeration compressor of the refrigeration unit is always operated below an upper loading limit.
Patent DE-3513251-A1 (DE)
Title: Air-cushion train
Inventor: LAMMERS ALBERT
IPC: B60V3/04
Filed: 1985-04-13
Abstract: The first application sets the train on normal rails by means of holders on an air cushion so that it can hover. By means of grooves in the surface, near to the ground, of the holders, a path is provided through which the compressed air of the air cushion is forced out of the air cushion around many corners, which saves energy. Likewise, for the same reason, the air is guided around a sharp corner once more before leaving the air cushion. The underside of the train is designed in such a way that it resembles a funnel so that the inflowing air stream is compressed and slightly lifts up the train so that it can hover on the second air cushion produced in this way, which saves energy for the production of the air cushion on the holders. Rapidly rotating threaded tubes are to protrude into this air cushion, suck the air backwards and thus provide propulsion = drive for the train, this is reversed for braking. Air columns are to permit rapid starting and landing on air as a result of vertical, rotating threaded tubes. Likewise, rotating threaded tubes are to suck air up from the direction of the side wind in order to produce a particularly good lateral stabilisation. In bends, the holders are to be inclined as far as is required for safety. The holders can, however, also ... at an angle of for example 45 DEG  from the horizontal whilst omitting those holders which were provided for the inside of the rail heads ...

Patent DE-3525230-A1 (DE)
Title: Filtration apparatus
Inventor: HOELBLING SIGBERT
IPC: B01D29/66
Filed: 1985-07-15
Abstract: Into a filtration apparatus is integrated a backwash apparatus which is permanently connected by a backwash vessel to the filtrate outlet line from the filter element or a group of filter elements, so that by temporary shut-off of the filtrate outlet line downstream of the backwash vessel and production of an overpressure in the filtrate contained in the backwash vessel, a predeterminable amount of filtrate is used as backwash medium. The filtrate is reliably separated off during this from the medium used to produce the overpressure. The filtration apparatus, by means of a time controller, solely by controlling its valves and pumps, can operate in a push-pull manner in previously established or adjustable time intervals in filtration mode and backwash mode. Preferred applicability is in cross-flow filtration circuits.

Patent DE-3536793-A1 (DE)
Title: Ear plug
IPC: A61F11/08
Filed: 1985-10-16
Abstract: The commercially available ear plugs are disliked because they are difficult to handle and sometimes are not very hygienic. Therefore, an ear plug was developed which will be more frequently worn because it is easy to handle and provides high comfort on wearing and improved hygiene. This object is achieved in that the elastic outer covering is preferably filled with a foamed material, cottonwool or a nonwoven and possesses a centrically arranged shaft. This shaft has a spherical or umbrella-like tip and a closing plate sitting between the filling and the lid. In another embodiment of the ear plug the shaft which is extended beyond the closing plate projects through the lid as a handle. These arrangements permit direct insertion into the auditory canal without manipulation of the ear plug which is extremely soft by adaptation of the soft outer covering to the contour of the auditory canal.

Title: Appliance for setting an indicator device for the working depth of a ground-cultivating machine
Inventor: SCHWERIN GUENTHER
IPC: A01B63/114
Filed: 1986-03-07
Abstract: What is proposed is an appliance (28) for calibrating an indicator device (27) for the working depth of a plough (12) articulated on a tractor (10), in which the working depth is derived from the position-dependent signals of a first sensor (18). A microprocessor (19) determines a tractor standstill from speed-dependent signals of a second sensor (21); with a calibration signal being set simultaneously on a drop switch (26), after a dropping action of the plough (12), with subsequent settling on the ground, the position-dependent signals control the indicator device (27) to the value zero. By means of this stored repeatable zero setting, during subsequent ploughing the working depth of the plough (12) is derived from the signals of the first sensor (18) and is indicated to the driver in the cab of the tractor (10). <IMAGE>

Patent DE-3615089-A1 (DE)
Title: Aircraft having roller wings
Inventor: WITTENBORN WOLFRAM
IPC: F03D3/00
Filed: 1986-05-03
Abstract: In the case of conventional drives for aircraft, such as propellers, jet propulsion or a helicopter rotor, for example, major parts are moved at high speed (approximately at the speed of sound) which results in severe noise emission and low efficiency. Driving by means of the wings avoids this, using a principle which is known from birds. However, I am not working with beating wings but with wings which rotate like rollers around a major axis which is parallel to their longitudinal axes. A design of such a "roller-wing aircraft" is sketched in the figure. It is best to use 3 wings per roller wing, and their incidence angles can then be controlled such that the propulsion and lift are constant <- vibration-free flight. This control is effected using actuating motors which are controlled using electronic data processing techniques. This concept of the roller wing can also be used for wind-driven power stations. <IMAGE>
