Title: Adaptive two-of-three comparator
Inventor: SCHIWEK LUTZ-WERNER DIPL ING
IPC: G06F11/18
Filed: 1983-08-25
Abstract: The invention relates to an adaptive two-of-three comparator for comparing the coincidence of a plurality of bit information items arriving on separate channels, with output of the information items which coincide on at least two channels. In this process, the corresponding information item from each channel is passed via an assigned AND element which, depending on the occurrence or absence of an error signal of a preceding integrity-based OK memory can block this channel by switching it off, it being possible to reset the OK memories of respectively assigned equivalence elements, at which the various bit information items are present, as well as following, logical OR elements for generating the error signals. Independently of this, a fail-safe setting of the memories is provided for switching the failed channel on again. In order to make the switching on again of a failed and repaired channel particularly simple and able to be performed without signals relating to integrity, the invention proposes provision of an automatic facility for switching on the failed channel again, evaluation being carried out of the simultaneous and equivalent dynamic logic change of all incoming bit information items (a, b, c) from logical 1 to logical 0 and vice versa, which only occurs in the case of correct transmission, for a setting of the OK memories (10, 11, 12). The generation of a fail-safe setting signal by the computer is no longer necessary and there are no ... Original abstract incomplete. <IMAGE>

Title: Device for monitoring the velocity of a gas flow in a duct
Inventor: PIEREN HEINZ
IPC: G01P5/12
Filed: 1983-08-30
Abstract: Device for monitoring the velocity of a gas flow in a duct, in particular for the smoke suction system of a multipoint line smoke alarm. The device has a sensor (10) which is formed by a temperature-sensitive heated element and is arranged directly in the gas flow. The sensor (10) is connected to a temperature compensation circuit (11) which serves for compensating the temperature fluctuations of the gas. A set-point/actual-value comparison circuit (13) serves for monitoring the voltage of the sensor (10), which depends on the velocity of the gas. If the gas velocity over- or undershoots the set-point value which has been set by means of a potentiometer (12), the comparison circuit (13) activates a fault circuit (15) via a time-delay circuit (14). The fault indication is conducted, e.g. to a fire reporting centre. A measurement output circuit (17) serves for setting the limiting value of the gas velocity during commissioning of the device. A heating circuit (20) serves for heating gas suction points should they be blocked by icing. 
<??>The device is particularly suitable for monitoring in the case of special applications, e.g. in EDP rooms, high-bay warehouses, or in areas where temperatures are below 0 DEG C.

Title: Pedal drive, in particular for a cycle or the like
Inventor: BACKERS HEINZ-CHRISTIAN
IPC: B62M1/36
Filed: 1983-12-21
Abstract: Cycles or other vehicles which are driven by pedalling usually have a pedal drive which requires a pedalling movement along a circular path. Such a known drive is unfavourable in physiological and ergonomic terms. In particular, it does not permit an effective application of force to the same degree as a function of the relative position of the pedal cranks. For this purpose, the invention proposes that the pedal arms which bear the pedals (10) should be arranged off-centre on a power take-off wheel (21, 25) and that as a function of the turning angle of the power take-off wheel (21, 25) the inclination of each pedal crank (11) should be varied by means of a compensation gearing (12) assigned to each pedal crank (11) in such a way that the pedals (10) move on an approximately linear path, that is to say a conversion from a transversal into a rotating movement takes place. <IMAGE>
