In a preferred embodiment, inlet and outlet manifolds for a forced electrolyte flow battery, the manifolds having nonuniform cross-sections. The inlet manifold extends along the base of the battery cells and tapers from a large cross-section at the inlet end thereof to a small cross-section at the closed opposite end of the manifold. The outlet manifold has electrolyte outlets at either end of the manifold and tapers from a small cross-section at the middle of the manifold to large cross-sections at the electrolyte outlets of the manifolds. The inlet and outlets to and from the inlet and outlet manifolds are arranged, respectively, such that the header connected to the inlet manifold is larger in cross-section than the cross-section of the inlet manifold at that point and the headers connected to the outlet manifold are larger in cross-section than the cross-sections of the outlet manifold at that point.

Tapered manifold for batteries requiring forced electrolyte flow

In a preferred embodiment, voltage control system and method which include providing voltage sensing and control circuitry which measures the output voltage of a battery and provides an output signal to a flow control valve to cause the flow control valve to reduce the rate of flow of electrolyte when the output voltage of the battery is below a desired level and to cause the flow control valve to increase the rate of flow of electrolyte when the output voltage of the battery is above a desired level. The flow control valve may be a binary controlled solenoid valve responsive to a pulse-width-modulated signal from the sensing and control circuitry.

Automatic voltage control system and method for forced electrolyte flow

Waveform inputs are sampled to provide vector inputs which are coupled to respective ones of a plurality of series connected time delay stages in a processing circuit. Each vector is weighted, or amplified, and time delayed by each stage between its input point and the circuit output. Each stage has switched capacitors and an operational amplifier. The delay of each stage is the period of the capacitor switching frequency. All of the components in the stages and vector input circuitry are solid state switches, capacitors or operational amplifiers and therefore are especially suitable for integration in a monolithic or film substrate. The circuit is particularly adapted to beam steering a plurality of waveform inputs from an array of hydrophones.
