Patent DE-3825114-A1 (DE)
Inventor: ROSHOP DIETER DIPL ING
IPC: H02K7/102
Filed: 1988-07-23
Abstract: An electric motor with a brake which acts automatically when the motor is switched off comprises a locally fixed braking surface and a rotatable brake armature (5), which can be pressed against the braking surface by the force of a spring (4). The armature is attached to the rotor (2) of the motor by the magnetic flux of the motor and is rotatable relative to the rotor through an angle of rotation limited by abutments. The abutments are defined by first wedge surfaces (11) which are inclined obliquely to the rotor axis and project out in rotor axis direction from the plane of the end face (3) of the rotor and by respectively associated second wedge surfaces (14) on the brake armature (5), the first wedge surfaces (11) being arranged at the end face (3) of the rotor lamination packet (2). The interaction of the first and second wedge surfaces, on actuation of the brake, causes the armature (5) to be urged with additional force against the braking surface. <IMAGE>

Title: Heating boiler
Inventor: NOACK ROLF DR
IPC: F24H1/28
Filed: 1988-09-23
Abstract: In the case of a heating boiler with a reversing combustion chamber (1) and smoke tubes (3) leading to a waste-gas collector (5), the waste-gas temperatures are to be lowered to an extremely low value, without falling below a minimum value required for the chimney. The smoke tubes (3) are therefore considerably lengthened and, for this purpose, possess additional indentations (6') in the rear extended region of the water space (4'), as a result of which the smoke tubes (3) act here as an integrated residual heat exchanger. The falling below a minimum waste-gas temperature is prevented by short-circuit smoke tubes (7) from the reversing combustion chamber (1) to the waste-gas collector (5), which, if required, ensure the opening of a shut-off flap (12) for a short-circuit flow. <IMAGE>
Patent DE-3905416-A1 (DE)
Inventor: WINDBOW GRAHAM ARTHUR
IPC: G01V1/137
Filed: 1989-02-22
Abstract: For converting tube waves into body waves downhole for seismic exploration, a rotary valve tube wave source (8) is used for producing swept frequency tube waves that are injected into a liquid-filled tubing (1) or wellbore (2). The tube waves are converted to body waves by an elongate tube wave converter (5) located at a selected position downhole. The tube wave converter comprises an elongate metal body that preferably substantially fills the wellbore or tubing and has a preferred shape in order to convert efficiently the tube waves to body waves at the selected position downhole. The converter has a strong acoustic impedance contrast with the liquid in the wellbore or tubing. <IMAGE>

Title: Remote-control circuit for a DC load
Inventor: FALLER CLEMENS DIPL ING
IPC: G08C19/30
Filed: 1989-02-25
Abstract: The invention relates to a remote-control circuit for a load (V) having control input (4), such as a multi-ring chime, which is connected to an AC source via a rectifier/filter circuit or a rectifier circuit, one control signal triggering one specific effect, for example the operation of a chime. A problem consists in that transmission of the control signal has hitherto required, in addition to the two strands of the power supply, at least a third line or an expensive RF transmission. A third line is associated with increased expenditure, and in particular, only two lines are often available, for example when subsequently installing more modern chime devices in old buildings, where there has so far been only a two-core bell line available. The solution of the problem consists in providing a short-circuiting switch (S) for the rectifier circuit (D1), and a storage medium which is charged up when the short-circuiting switch (S) is open and is discharged when the short-circuiting switch (S) is closed, the charge delivering a control signal to the control input (4) of the load (V) via a control circuit (1). <IMAGE>

Title: Inlet manifold pressure control for turbocharged engine - has processor controlled inlet valve and controlled by=pass for turbine
Inventor: FORTNAGEL MANFRED DR ING
IPC: F02B3/06
Filed: 1989-12-01
Abstract: The turbo-charged engine has a first control valve (V1) between the turbocharger (2) and the inlet, and a second control valve (V2) in a by-pass (7) for the turbine of the exhaust driven turbocharger.
