Abstract: An integrated solar roof system, consisting of insulated roofing panels and collector panels, and method of producing same wherein the base assembly of the collector panel may be used with either an air or liquid absorber and is both an insulator and radiation shield as well as an integral structural part of the roof of the building on which it is mounted. The construction of the panels lends itself to mass production techniques and the efficient use of materials making the panels cost effective. The collector panels are also suitable for use as independently mounted units, functioning only as collectors and not as roofing members. Collector panels and insulated roofing panels, being identical in size and installation method, and said installation method being simple and quick, a suitable combination of panels may become a complete roof with minimal installation labor.

Abstract: A method of making a punching mechanism for multiple selective perforation of a computer compatible card for use with a punch selector bank having slidable rods which are engaged in a locked position by operator manipulation of corresponding keys is disclosed. The ends of the selector rods are adjacent the butt end of punches slidable in a fixed plate. A punch plate slidably receives the opposite cutting end of the punches. A perforate template is secured to the punch plate and spaced apart to provide a card slot between the punch and template. The punch includes a latching switch mechanism to insure the card is properly inserted which will not permit reciprocation of the punch unless the card is properly inserted. An eccentric drive is adapted to reciprocate the guide and template toward the punches and the punches blocked by the locked rods will perforate the inserted card. A special punch is adapted to sever a portion of the card after it is in the card slot to orient the card for subsequent processing.

Abstract: A compact, versatile voting machine is disclosed having adaptability for use with various vote registering devices such as tally counters and punch card apparatus. The voting machine includes a selector mechanism having a series of parallel columns housing voter operated key slides. A vertical interlock mechanism includes ball housing blocks which are alternately disposed between the key slides and house displaceable interlock balls in a tool line. The cam blocks are adjustable to limit the effective length of the tool line to establish groupings of candidates from which a single selection can be made. A magazine at the top of each column is adjustable to permit multiple selections from a grouping. Actuation of a key cams the interlock balls into the tool line, and when a predetermined number of voter selections have been made no additional keys can be actuated as they are blocked by the tool line.
