The disclosure relates to an electronic memory system, and more specifically, to a system for storing data in an adjustably partitionable memory array, and a method to store data in an adjustably partitionable memory array. According to an embodiment of the disclosure, a system to store data in an adjustably partitionable memory array is provided, the system including a plurality of memory cells arranged in an array of rows and columns, a plurality of bit lines, and a plurality of switches, wherein each bit line is electrically coupled to a column of memory cells and each bit line comprises a switch configured to allow the respective bit line to be partitioned by opening of the switch.

An amino acid complex of the formula I,where M is selected from among Fe, Co, Ni, Pd, Pt and Ir, preferably Ni, can be used for the polymerization of olefins.

Amino acid complexes and the use thereof in producing olefin polymers

A piston pump, in accordance with several embodiments, comprises a suction chamber into which fluid medium enters from an inlet line via a suction valve, beginning at the outset of a delivery stroke of the piston pump, without a build-up of intake negative pressure during the delivery stroke of the piston, and is particularly adapted to prevent vapor bubble formation. A reliable pump closure is ensured in the vicinity of the pump outlet, independent of the spring action of a return spring, which bears against the piston, in that any fluid medium entering the suction chamber of the pump contacts the piston in a direction producing reinforcement of the outlet closure pressure. In accordance with preferred embodiments, the piston may be a partially hollow or entirely hollow piston instead of a solid one. Variously designed connecting elements and relief valve arrangements for the conducting of the fluid medium from the suction chamber of the fuel pump to an armature compartment are provided, with the objective that the piston pump have a minimum inactive flow volume.

An ignition spark emitter for a fuel operated heating device has two electrodes which are addressed by a transformer and deliver ignition sparks. The ignition electrodes are secured at a housing of the ignition spark emitter which also contains the transformer and the power supply unit of the ignition spark emitter. A plug connector, which preferably, is disposed in the form of a plug-in unit is provided at the housing of the ignition spark emitter, and not only establishes the electrical connection of the ignition spark emitter, but also serves for its mounting, preferably, in proximity of the nozzle assembly of the burner. One of the ignition electrodes, in connection with a ground circuit, can be utilized for ionization flame monitoring via the combustion tube of the heating device, whereby the ionization flame monitor appropriatelylame monitoring via the combustion tube of the heating device, whereby the ionization flame monitor appropriately is operated in a time multiplex manner. An evaluation device, whose output signal is transmitted for ionization flame monitoring via the plug connector for further processing, is also disposed in the emitter housing.

Ignition spark emitter and fuel operated heating device equipped

A fuel-operated vehicle heater especially of the type intended as an auxiliary or additional vehicle heater and which has a nozzle sitting on a nozzle holder to which fuel is fed from a fuel line by a filter, a fuel pump and an interposed solenoid valve. In a preferred embodiment heater, the nozzle holder, fuel pump, filter and solenoid valve form a subassembly that can be handled as a single unit. Advantageously, this subassembly can be fastened by screws to a flange within a housing part of the heater. On this flange can also be fastened an ignition spark emitter an a central connecting device, such as a burner motor. Advantageously, the feed line and/or the return line for the fuel supply are formed in the flange.

Fuel operated vehicle heater
