Patent ES-450192-A1 (ES)
Title: Solar energy conversion
IPC: H01L31/00
Filed: 1976-07-27
Abstract: Solar energy conversion is provided by a structure formed of a plurality of photovoltaic sources. An electrolyte wets the sources. Upon exposure to light the photovoltaic sources cause a current to flow in the electrolyte producing an electrochemical reaction. The products of this reaction may then be collected and stored. In a preferred embodiment the electrolyte is an aqueous solution of hydrogen iodide, and the hydrogen produced by the electrochemical reaction may be stored, burned as a fuel or used in a fuel cell to produce electrical energy.

Title: Apparatus for collecting extruded lengths of material into groups
IPC: B65G57/18
Filed: 1977-11-16
Abstract: Lengths of material are collected in side-by-side relation in a group and delivered as a group to a receiving station by an apparatus which includes a support table constituted by a number of spaced parallel arms pivoted coaxially with each other about one end. Each arm has a finger which projects upward above the arm and which can be moved toward the pivot for moving the lengths laterally of themselves towards a stop adjacent the pivoted ends of the arms, and during this movement the arms are inclined downward towards their pivot at such an angle that the fingers need exert only a small force to move the lengths towards the stop. A mechanism is provided for moving lengths of material individually or collectively on to the support table for movement by the fingers towards the stop, and a device spaced from the pivots emits a signal when the combined width of the lengths of material which have been moved towards the stop by the fingers reaches a predetermined value, and this signal initiates operation of a mechanism for moving the group of lengths having the predetermined width past the stop to the receiving station.

Title: Solid state switching system for coupling a d-c power supply to a load
IPC: H03K17/06
Filed: 1980-09-10
Abstract: A d-c power supply is connected to a load via a power transistor triggered to its saturation condition by periodically recurring pulses having a time separation between successive pulses less than the transistor's storage time.
