Abstract: Energy expended by pedestrian or vehicular traffic is captured by a device which includes a plurality of tread plates which when depressed by traffic thereupon drive rocker arms mounted by one way clutches on a shaft. The rocker arms are spring biased upwardly to keep the tread plates normally raised so that the tread plates return to their initial position after being depressed. Preferably, the shaft is connected to a generator, and the generator to a battery so as to store electrically the energy captured mechanically. By using the aforedescribed configuration a relatively thin device is achieved which can be conveniently installed under a carpet and used in the doorways of buildings or other heavy traffic areas.

Abstract: The present invention relates to a pad capable of high liquid retention and capable of self-metering of liquid from the pad upon application of pressure. Such pads are highly desirable in lubricating applications and serve well as printers and ink reservoir for computers, markers and printing machines. The process comprises mixing a void former, typically a non-reactive salt of a size range chosen between 2 and 450 microns with a polymeric material in a weight ratio of 2.5:1 to 10:1 salt to polymer. The polymer is heated and the salt dispersed therein to form a salt-polymer composite. The composite is fed to an extruder and extruded to a desired shape, a dense skin being formed on the surface of the extruded polymer. Subsequently, the extruded polymer is cut, the salt is leached from the polymeric matric with a suitable solvent, and the leached extruded polymeric matrix is dried. The skin layer has narrower channels and a lower void volume than the adjacent reservoir column.

Abstract: A process and two embodiments of an apparatus are disclosed for displaying, on the screen of a conventional home television receiver, curves illustrating analog signal potential functions of the form U(x,y). The process generally requires generating first and second saw-tooth signals synchronized with the vertical and horizontal sync. signals of the picture raster of the home television receiver. At least part of each of the signal potentials U.sub.y and U.sub.x are then compared with the first and second saw-tooth signals to generate first and second impulse signals respectively when equal potential conditions are observed. The first impulse signal is then differentiated with respect to time to form a gate impulse signal of adjustable width for controlling the processing of signal potential U.sub.x. The second impulse signal is differentiated with respect to time to form a brightness control signal for output to the home television receiver.

Abstract: Hydrogen and Oxygen are produced by photoelectrically-induced electrolysis wherein solar and/or laser light is passed through a thin layer of a water-caustic soda solution to ionize the solution adjacent an anode. A cathode spaced from the anode and connected thereto by a diode circuit, including a resistance, is used to prevent current flow between the anode and cathode until the potential therebetween exceeds a threshold two volts and preferably 2.4 volts. Upon sufficient ionization in the thin layer of solution, the potential between the anode and cathode exceeds the threshold and current flows therebetween, causing hydrogen gas to form at the cathode. Circulation of the solution between the anode and cathode is caused by convection due to heating of the fluid with solar or laser light.
