A fluid dispenser for dispensing liquid detergents, soaps and germicides. A pressure plate imparts a squeezing force to a flexible reservoir containing the liquid material to force the material therefrom. A battery operated photoelectric device is positioned adjacent the dispensing valve which is opened for a timed period upon locating an object such as a hand, near the photoelectric device. Also, a device is provided to control the power to the photoelectric device upon sensing the condition of the ambient room lighting.

The present invention relates generally to devices that are adapted to store energy. More specifically, one embodiment of the present invention is a battery that employs a plurality of compartments which hold cell elements that generate electricity through an electrochemical reaction. In addition, one embodiment of the present invention employs arcuate end compartments that are adapted to hold a non-compressible fluid that aids in the reaction of internal pressure loads generated by the electrochemical reaction. This fluid in one embodiment may be put in compression during manufacturing of the battery. Thus, the present invention enables the internal compartment walls to impart sufficient compression on the cell elements to enhance the battery's efficiency and useful life.

A seawater activated battery plate, and a method of making the same, utilizing an electrically conducting grid and an active reducible material primarily constituting lead chloride adhering to the grid such that the grid is exposed at a surface of the active material, the material adjacent the grid primarily constituting porous lead and a metal chloride. The battery plate is characterized by its inexpensive method of manufacture, its quick activation even in cold seawater, its absence of significant voltage peaking at initial discharge and uniform voltage generation during discharge.
