Patent DE-3011360-A1 (DE)
Title: Compressed air supply for turbine driven vehicle - has compressor linked to turbine by selective flow restriction
Inventor: BLASE HEINRICH DIPL ING
IPC: B60T15/48
Filed: 1980-03-25
Abstract: The compressed air supply for a vehicle has the compressor (13) linked to the compressor (1) of the turbine drive by a control valve (4). This provides a direct connection to the compressor up to a set pressure in the reservoir (22). Above the set pressure the control valve connects the turbine to the compressor via a flow restriction (3) while excess air is dumped via a vent line (18) from the pressure control valve (20). For low reservoir pressures the air supply from the turbine is taken directly to the compressor for a rapid filling of the reservoir, with a feedback loop (10) from the pressure control valve to the flow control valve (4). When excess air is dumped the flow restriction prevents a direct venting of the turbine, and limits the air loss to a set rate, so that the turbine efficiency is not affected.

Title: Electronic temp. controller with accuracy of display resolution - using incremental display signals as switching signals applied in relay switching circuit
Inventor: LANGENBRUNNER GUNTRAM
IPC: G05D23/20
Filed: 1980-09-15
Abstract: An electronic temp. control system combines thermostatic and indication functions so that the control accuracy of the thermostat exactly corresp. to the resolution of the display unit. The required temp. is maintained with small control variations and energy savings are achieved to room heating applications. Incrementally controlled outputs of a circuit for displaying the controlled temp. are used as switching circuit. The switching accuracy of the system thus corresp. to the resolution of the incremented actual value indicator. The temp. dependent voltage obtained from the PN junction of a silicon diode (1) is matched to the input voltage range of the indicator circuit (3) using an operational amplifier circuit (2). Reference sources for several different measurement and display ranges are switched by bilateral analogue switches (6,7,8,9).

Title: Method and arrangement for detecting machine-internal variables in electrical machines
Inventor: ANDRESEN EGON PROF DR ING
IPC: G01R31/34
Filed: 1981-01-24
Abstract: The invention is based on a method for detecting machine-internal variables in electrical machines, particularly three-phase squirrel-cage motors, using magnetic-field variables or probes detecting changes therein with respect to time in or at the air gap of the machines. The invention consists of the signals of a plurality of probe pairs (A/B, C/D) which are mutually offset through a rotation angle with respect to one another, preferably through 120 DEG , and are aligned axially with respect to the machine axis, being detected and evaluated in order to determine a local flux and/or incremental rotor position, the flux being determined from the fundamental component of the signal of one or more probe pairs while eliminating the harmonic components of these signals, and the position being determined by counting the harmonics, while eliminating the fundamental component of the signals. The advantages are, in particular, that both the flux and the position of the machine can be determined simply and without any change to the active part of the machine. Tachometer machines or rotation angle sensors can be dispensed with. <IMAGE>
