Title: Vacuum sewer arrangement
Inventor: LINDROOS GUNNAR
IPC: E03D11/00
Filed: 1990-12-20
Granted: 2000-08-22
Abstract: A vacuum sewer arrangement comprises a bowl connected to a sewer pipe provided with means for establishing, in the sewer pipe, a vacuum sufficient for obtaining efficient sewage transport. There is a normally-closed sewer valve connecting the bowl to the sewer pipe and a control device for controlling operation of the sewer valve to allow discharge of sewage from the bowl to the sewer pipe. There is also an air inlet duct for letting air into the sewer pipe separately from the bowl. For controlling flow of air through the air inlet duct into the sewer pipe, when the sewer pipe is under proper vacuum for effective sewage transport, there is an air inlet valve with means operating it in response to pressure variations in the sewer pipe. Such pressure variations occur when the sewage discharged from the bowl has passed the point where the air inlet duct is connected to the sewer pipe.      This ensures that the air inlet valve operates accurately and securely.

Granted: 1999-09-14
Abstract: The provision of an electric rotating machine which can reduce the mechanical and thermal loads applied thereto. Coil arms (534, 537, 20b, 21b, 20d, 21d) and coil trunks (533, 536, 20e, 21e) are provided in roughly parallel orientation to the end faces of an armature core (520, 11) only through insulating rings or spacers (560, 590, 20a, 21a, 20c, 21c). Metal brush (910, 81) is disposed on coil arms, whereby the overall length of the armature can be remarkably shortened. In addition, a commutator, conventionally necessary, can be eliminated, whereby the length of the production process for the armature can be reduced.     Moreover, in an arrangement where projections (534c) of the upper coil arm are fit in holes of the insulating spacer, as the displacement of the upper coil arm towards the outer periphery is regulated, the length of axial protrusions of the upper coil arm from the end face of the armature core can be minimized. In addition, as extension portions (538, 20g, 20h) and of the coil trunks are strongly pressed against and fixed to the side of armature core by fixing members (570, 30), the resistance to the centrifugal force can be remarkably improved. Furthermore, as the extension portion of the lower coil arm is fit in a recessed part of the insulating spacer, the displacement of the lower coil arm in the axial direction towards the outer periphery can be prevented.
