Title: Electric machine commutator arrangement - leads end of armature coils of wave winding through slots in direction opposing direction of winding
Inventor: ROTTMERHUSEN HANS HERMANN
IPC: H02K23/26
Filed: 1989-12-29
Abstract: The number of armature coils, which are necessary for the interconnection of the parallel armature current branches, corresponds to the number of the commutator segments divided by the number of pole pairs. These coils are arranged at the armature such that, respectively the end (3) of the armature coils in the winding form of a wave winding, is led through the armature slots in the opposing direction of the winding direction of the armature winding. The end (3) of the armature coils is arranged at those commutator segments which mutually have an angular distance of two pole pitches. The winding wire for the interconnection of the parallel armature current branches takes part in forming the torque of the motor and represents a positive part of the armature winding. Brushes are arranged corresp. to the brush arrangement of the wave winding to the commutator. USE/ADVANTAGE - Electrical interconnection of parallel armature current paths of loop winding carried out across commutator, without corresp. bridge plates according to main patent.

Title: Open=end spinning rotor - has extended life by pressing spindle from rotor head to region overall length
Inventor: STAHLECKER FRITZ
IPC: D01H4/12
Filed: 1990-03-09
Abstract: The drive spindle affixed to the backc of a rotor head becomes worn at the end where it is in contact with the spur bearing. When the spindle is pressed outward slightly from the back of the rotor head, the overall length is regained. Pref. the spindle in the machine, is mounted on bearings, and is belt driven. To retain a constant position, the end presses against a spur bearing. After a time, this end bearing surface wears down, reducing the overall length of the spindle plus rotor head. The spindle has a press fit to the back plate of the rotor head so that pressure on --the end will push the spindle dia. along the bore. The face may then be re-ground to -attain the correct overall length after reducing the distance from the end to the back of the rotor interior.
Patent DE-4009449-A1 (DE)
Inventor: STARCK GUENTER DIPL ING
IPC: B61H7/08
Filed: 1990-03-23
Abstract: The eddy current rail track brake has an adjustment bearing for holding the eddy current brake magnet 1 in its operative position, which bearing comprises a first adjustment part 33 on the eddy current brake magnet and a second adjustment part 34 on a non-sprung vehicle part. The first, upper adjustment part 33 is connected to the eddy current brake magnet 1 in a vertically and horizontally adjustable fashion, whilst the second lower adjustment part 34 is guided in a vertically displaceable manner on the non-sprung vehicle part 25 and can be lowered counter to the pretensioning of a pretensioned spring 30. The excitation of the eddy current brake magnet can be reduced as the travel speed decreases, in such a way that the attraction force does not exceed a specific maximum value. The pretensioning of the spring 30 is dimensioned to receive this attaction force without further compression of the spring 30. If the reduction of the excitation of the eddy current brake magnet 1 fails, the extremely high attraction force which occurs when the vehicle is travelling slowly or is stationary compresses the spring 30 and the eddy current brake magnet moves to the emergency position resting on the rail. As a result, overloading of the carrier elements of the eddy current brake magnet 1 is prevented. <IMAGE>

Title: Continuous waste water disinfection - using indicator to monitor disinfection dwell time
Inventor: KINZLER GEORG
IPC: C02F1/02
Filed: 1990-05-18
Abstract: Continuous disinfection of micro-organism-laden waters (esp. purificn. water used in genetics) involves heating to the disinfection temp. by heat exchange with and/or direct injection of steam, holding at temp. for a preset minimum dwell time and then discharging. The novelty is that an indicator is periodically injected into the heated waste water immediately before entry into the dwell stage and is detected in the waste water leaving the dwell stage. The time difference between indicator injection and detection (i.e. the actual dwell time) is compared with the preset min. dwell time and, if the actual dwell time is less than the preset minimum dwell time, an alarm signal, a switch-off signal and/or a signal for repeated feed of the waste water to the dwell stage is given. (B) Equipment for carrying out the process is also claimed. ADVANTAGE - The requisite dwell time is reliably maintained or measures are automatically undertaken to ensure that waste waters contg. living micro-organisms (bacteria, viruses, germs, etc.) are not discharged to drains.

Patent DE-4116267-A1 (DE)
Inventor: SCHMID RENE P
IPC: E21D11/38
Filed: 1991-05-17
Abstract: A process is disclosed for sealing a joint between two sections, in particular between two concrete sections. A hose-like, unstable body made of a non self-supporting material is mounted in the area of the joint, at the surface of the joint, then the hose-like body is filled with a supporting medium and is closed. The second concrete section is then finished and the supporting medium is removed from the hose-like body, that collapses due to its instability, creating an injection path for a sealing medium. A sealing medium is then injected into the injection path thus obtained and penetrates into faults in the joint area, for example crevice-like faults in the concrete sections, sealing the joint area. An element for sealing such a joint comprises a hose-like, unstable body that forms an injection path for a sealing medium, with closable free ends, capable of being mounted on the surface of the joint and with a cavity filled with at least one supporting medium.
