Title: Data storage control circuitry for indicating faulty elements - uses additional reading conductors with manufactured break points
IPC: G11C29/00
Filed: 1973-10-11
Abstract: The addition provides a further simple method of denoting memory elements in an integrated data store, which cannot be used due to the manufacturing process. These unusable elements, when accessed, emit signals which indicate their non-usability and the control circuitry shifts the word bit to the next usable element. A second read line is now connected parallel to the first to a word line for accessing a memory element. This additional read line is connected to the word line through a diode associated with each element. The additional line is also linked through an interrupt point prepared during manufacture, so that the connection can be broken if the element proves to be faulty. The diode is on the work line side of the break line.

IPC: F15B13/042
Filed: 1973-11-30
Abstract: Improvement of hydraulic fluid servo drives for the remote control of a movable motor element by means of a lever servo drive, which are connected exclusively by a pipe line. For each position of the movable motor element, a single position of the control mechanism is effected independent of the resistive force opposed by the movable element. The pressure to maintain the balance in the arrangement in any position assumed by the control lever is itself adjustable and the necessary pressure variations in the lever position allow no lever movement. There are two hydraulic mechanisms, one hydrodynamic to regulate the pressure and the other hydrostatic to adjust the movable motor element.

Title: Hydraulic steering system for endless tracked vehicles - has pressure regulator valve to maintain steering pressure at low engine speed
Inventor: KLEINEISEL GUSTAV
IPC: B62D11/10
Filed: 1974-07-18
Abstract: A manually adjustable throttle valve is provided between the auxiliary hydraulic pump driven corresponding to engine speed and the output pressure receivers. A pressure regulator maintains a return pressure of 11 atmospheres to the return tank. The steering is effected by a cam actuated by the steering wheel, whereby the pressure reduction valves are both closed in the neutral (straight adhead) position, so that equal pressure (11 atmospheres) is maintained in the output pressure receivers. Actuating the cam causes a pressure reduction in the corresponding pressure receiver via the switch over valve to bring about an unequal driving speed to one side of the vehicle.
