Patent DE-2702279-A1 (DE)
Inventor: SCHMID JOHANN
IPC: G08C15/00
Filed: 1977-01-20
Abstract: So that a remote control system can be extended as required, simply by adding input and output units, after release by a central unit (1, 2) each input unit (4) receives control commands from the central unit (1,2) via a control distribution line (19,20), which is common to all input units (4). For the control commands, the respective input unit (4) translates the information supplied by a transmitter (3) into a telegram word, which is structured in the same way for all input units (4), and contains the target address as well as the information. When a "read" control command is released and applied, the telegram word is put on a data distribution line (23, 24), which is common to all input units (4), and which, when an "accept" control command supplied by the central unit (1, 2) is applied to the input unit (4), accepts the telegram word for onward transmission and takes it to the output units (8). The output units (8) accept the telegram word, when released by the central unit (1, 2) with an "accept" control command supplied by it, for further processing. <IMAGE>

Title: Automatic synchronisation system for sampling oscilloscopes - takes signal from second output of splitter in phase with input to feedback circuit comprising filter and VCO
Inventor: BENCZE JOZSEF DIPL ING
IPC: G01R13/34
Filed: 1977-04-25
Abstract: The automatically-synchronized system for sampling oscilloscopes operates with a double sampling sequence and requires no wide-band amplifier and divider. The h.f. signal being measured is fed directly to the input of the sampling circuit. A splitter has one output connected to the oscilloscope and produces a l.f. representation of the input signal. A signal in phase with the input is taken from the second output to a feedback circuit comprising a filter and v.c.o. The oscillator drives the sampling circuit in phase with the input. In the second sampling phase, the oscillator triggers sweep and step generators whose outputs are fed to a comparator. This supplies a phase-shifted sampling. The double operating mode provides time-multiplex operation of the sampling circuit and the amplifier and pulse-shaper circuit.

Title: Instantaneous fuel consumption indicator for motor vehicles - has gauge operated by signal from throttle for average indication
Inventor: FIALA ERNST PROF DR
IPC: F02B77/08
Filed: 1977-06-23
Abstract: An indicator (20) is supplied with a voltage from a battery (28) through a potentiometer (22). The potentiometer wiper arm (23) is moved by a link from the throttle (25) in the engine air intake (24). A switch (26) connected to the gearbox adds or removes extra resistance (27) according to the gear in which the vehicle is running. Since acceleration and deceleration occur for only short periods it is sufficient to indicate fuel consumption on the basis of constant speed running. At constant speed the fuel consumption is proportional to the air flow which depends on the throttle position. The use of this to indicate instantaneous fuel consumption is therefore sufficiently accurate.

Title: Determination of the condition of carbon bed - using test bed in parallel with main bed through which gas stream passes monitored by volumetric gas meter
IPC: B01D53/04
Filed: 1978-02-28
Abstract: The life of adsorber beds is checked out by taking a sample stream of gas and passing through a small test bed. To determine the life it is essential that the residence time/flow is the same for the large bed and the small bed. This is achieved by mounting a volumetric flowmeter on the small bed. A number of small beds can be mounted between inlet and outlet headers with provision for installing a double branch gas meter. Alternatively an angle branch meter can be used with an excess flow cap being mounted if the meter is removed. Another alternative is for each small bed to have a provision for mounting an individual single branch meter. Used for testing the life of activated carbon adsorber beds, used with solvent laden or radioactive component contg. air streams. Allows the residence time of the test bed to be quickly determined and hence the condition of the main bed.

Patent DE-2813418-A1 (DE)
Inventor: CURLANDER PAUL JOSEPH
IPC: G06F11/07
Filed: 1978-03-29
Abstract: In a plural unit system, particularly of the data processing type, controlled units such as tape drives, constitute status reporting units (SRUs) which report status including error conditions to one or more status analyzing units such as computers (CPUs), programmable controllers, and the like. Each of the SRUs has a register, such as a shift register, associated therewith for receiving error status indications. The signal state of the shift register when all zeros indicates error-free status, any nonzero state signifies an error. An OR circuit receives signals from all of the bit positions of each of the respective shift registers and combines same into an SRU group error indicating signal. A second register, also a shift register, associated with the respective SRUs receives the output of the OR circuit in one of its bit positions, the bit position indicating the address of the reporting SRU. The output of the two shift registers associated with each of the SRUs are serialized onto one wire and supplied to an intermediate shift register. Combined signal status in the intermediate shift register are then supplied to one or more status analyzing units in a two byte format, i.e., one byte for the address and a second byte for the error status. An appropriate status analyzing unit then determines the error condition of the SRU. If more than one SRU is in error, then the address byte will have more than one binary one indicating state requiring further analysis by the respective status analyzing units.

Title: Perpetual motion gyro system - generates propulsive force by being rotated in plane through axes of several rotating masses
Inventor: BORUTTA REINHARD
IPC: F03G3/08
Filed: 1978-06-08
Abstract: The drive for a u.f.o. makes use of the effect that, when a force acts in a direction at right angles to the axis of rotation of a rotating mass (K1,: K2), this produces a force in a direction (AB) at right angles to the original force and to the axis. This force is used to move the vehicle (Oj) in which the system is installed. The rotating masses (K1, K2) are driven from a shaft (Aw) via bevel gearing (Z, Z1, Z2). The masses are carried in bearings in a housing (G) which, itself, can be rotated via the hollow shaft (Hw). This latter rotation produces the force to which the system reacts by moving in the direction of the axis (AB).
