Title: Method for control of sub-munitions - involves determining orientation of striking surface by selective limitation of launching width
Inventor: RIEGER ULRICH DIPL ING
IPC: F42B12/58
Filed: 1990-05-04
Abstract: The sub-munitions are in the form of projectiles, bombs or mines which are ejected from a flying dispenser. With the lateral ejection of the sub-munitions, in addition to the control of the length and width of their attach surfaces, their lateral position and orientation in relation to the flight path of the dispenser are controlled together with the depth of attack within the attack field. To achieve this, the ejection width of the sub-munition is controlled individually with the aid of a brake activated by a timer, or is controllable by a known path extension device which is de-activated by the timer. USE/ADVANTAGE - For military purposes, involving a flying dispenser of sub-munitions whereby their attack surfaces are adjustable to a wide extent in accordance with their geometry and orientation in relation to the dispenser flight path.

Title: Throughflow water heater with safety cut=out - has monitoring circuit to switch off power if one or more heating elements have voltage applied with no water flow
Inventor: KRACHT ELMAR DIPL ING
IPC: F24H9/20
Filed: 1991-02-05
Abstract: The electric heating elements are in a triangular array over the three phase supply. Each end of each element is connected to the supply via a triac. A monitoring circuit measures the bias applied to each element. If any one element has bias applied, with no water flowing, then the fault detection circuit switches off the power to all the heating elements. The bias on the elements is compared with either the signal from the waterflow meter, or with the switch-off, switch-on signal from the control circuit. A simple failure mode immobilises the entire supply if a fault is detected. ADVANTAGE - No risk of burning out an element if triacs are faulty; increased safety.

Patent DE-4113957-A1 (DE)
Inventor: LUTAT MARTIN DIPL ING
IPC: F02M59/36
Filed: 1991-04-29
Abstract: In a fuel injection device for diesel engines comprising a pumping plunger 2 reciprocable in a cylinder 3 provided with a spill opening 6 controlled by a solenoid valve 7, a bore 5 is either closed to start injection or opened to end injection and the quantity of fuel delivered depends on the period when both the valve 7 and the bore 5 are closed. As shown the valve 7 is closed first, delivery starting when the bore 5 is closed by the plunger and ending when the valve is opened. Alternatively, Fig. 2 (not shown), delivery is started by closing of the valve and ended by the opening of the bore 5, the valve opening subsequently. An impact pick-up 13 signals the actual closing time of the valve to an electronic control unit 10 whereby the unit is able to take account of the time characteristic of the valve. Because the bore 5 is opened or closed while the valve is already closed, the time delay in the valve's operation is not a disadvantage and very small injection quantities are possible. <IMAGE>
