Patent DE-2727692-A1 (DE)
Inventor: ROHNER BENEDIKT
IPC: B42F17/12
Filed: 1977-06-20
Abstract: The pivoting plates (9) are designed in such a manner that they have a horizontal part (10) which projects beyond the card index box (1) and two spring legs (11) adjoining said part.

Title: Commutation disturbances detector in static converter - has AND=gate following each semiconductor switch and followed by timer connected to OR=gate
Inventor: ECKARDT RAINER DIPL ING
IPC: H02H7/127
Filed: 1977-07-13
Abstract: A commutation disturbances detector is used in a static converter. The converter consists of cyclically commutating semiconductor switches and each of these switches is preceded by an AND gate. A signal is generated in a pulse stage by the current flowing through the semiconductor switch. This signal and the ignition pulse of a cyclically following semiconductor switch are applied to the AND gate inputs through a resettable store. The AND gate output is connected to an OR gate common to all AND circuits and working into an ignition pulse blocking device. A timing stage adjusted to a longest possible commutation time follows each AND gate or OR gate.

Title: Water wave energy utilisation system - has floats arranged in pattern deflecting waves obliquely onto each other
Inventor: TORNABENE MICHAEL G
IPC: F03B13/18
Filed: 1977-12-17
Abstract: The system which uses the energy of water waves, has a large number of floats arranged to a predetermined pattern on the surface of the sea. The pattern is such that a first float is situated obliquely to the rear of a second one when seen in the direction of a first pressure movement of a mass of water, and the intervals between floats are such as to deflect a first water pressure wave obliquely, while the second float deflects it forwards and rearwards so as to strike the first one. This causes the first wave to collide with a second one. Each float is also so shaped as to deflect a wave obliquely towards one behind, so as to make full use of the remaining wave energy. Each float can be coupled to a lever, so that its up-and-down movement is converted into mechanical energy.

Title: Lidar beam direction measurement by opto-electronic method - is by dividing quadrant detector difference voltages by summed voltages
Inventor: HALLDORSSON THORSTEINN DIPL PH
IPC: G01S17/42
Filed: 1978-11-23
Abstract: An opto-electronic measurement arrangement for the direction of transmission of a laser detector of light scattering particles, or lidar enables unambiguous noise immune measurement of the direction to an accuracy better than 10-4 using direct electro-optical techniques. The scatter trace image of the laser source (10) transmitted beam in the earth's atmosphere is formed on a quadrant detector using a receiver telescope and associated optical system. The deviation of the beam from being parallel with the telescope optical axis is derived by dividing the difference voltages between individual quadrants by the sum of the individual quadrant voltages. The stopped collimated beam is split. One partial beam is fed to the receiver detector and the other via an interference filter and focussing lens to the quadrant detector.

Title: Vehicle steering control system - gives positive feel using rotational moment factor varying between zero and max. during each full rotation
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: G05D1/00
Filed: 1979-01-24
Abstract: The steering control is as in P2901612 and has the driving motor held fixed, so that rotation of the steering control housing about the control axis causes a twisting or the neutral axis of the system via a cog race of the housing engaging the base wheel. Upon rotation through 90 degrees, the rotational moment factor reduces to zero, with further rotation through to 180 degrees providing a reversal of the direction of action of the rotational moment factor, which again decreases to zero as rotation through to 270 degrees is affected. By further rotation through to 360 degrees the max rotational moment factor is again obtained in the initial direction of action. The rotational moment factor pref. also reduces in steps as the rate of rotation is increased.
