Abstract: ABSTRACT OF THE DISCLOSURE           A fastener installation head has a nut receiving passage, a transverse plunger passage having a reciprocating plunger therein, a feed means feeding nuts from the nut passage to the plunger passage and a stop means preventing nuts from entering the plunger passage except upon actuation of the feed means.  The stop means comprises two parallel cylindrical posts located on opposite sides of the nut passage at the intersection of the passages.  The cylindrical posts are resiliently biased into the fastener receiving passage and normally prevent fasteners from entering the plunger passage except upon actuation of the feed means.

Abstract: ABSTRACT          A simple production process for small-area semiconductor wafers is described.  To a large-area semiconductor wafer there is applied a soft solder plate to which is in turn applied a plate provided with a perforated grid pattern.  The whole is heated under load, whereby the solder is caused to migrate into the holes of the perforated grid pattern.  The semiconductor wafer is then exposed to a sandblast which removes the semicon-ductor material between the solder domes at a high speed, but removes the solder domes only slowly, until the semiconductor wafer has been divided up.  The solder domes are then used to contact the small-area semiconductor elements.

Abstract: PROCESS AND APPARATUS FOR SOLAR ENERGY                COLLECTION AND RETRIEVAL                          ABSTRACT         For collection, retrieval, and utilization of solar energy, there is taught a process and an apparatus wherein a photochemical fluid, containing an isomerizable compound, is passed through a collector for exposure to solar radiation to transform the isomerizable compound to a higher energy level isomer.  The irradiated fluid leaving the collector passes in heat exchange relationship with photochemical fluid entering the collector and then proceeds into a trigger reactor means.  In the trigger reactor means, higher energy level isomer in the irradiated fluid is triggered, such as by heat and/or catalyst contact, to revert to an isomerizable composition of a lower energy level isomer with exothermic release of heat in excess of that requisite for maintaining conversion of higher energy level isomer to lower energy level isomer.  The trigger reactor means is positioned in close proximity and/or desirably contiguous to or an integral portion of another heat exchanger through which is flowed a material adapted for storage at an elevated tempera-ture to receive that exothermic heat excess being released upon the higher to lower energy level isomer conversion.  The photo-chemical fluid, after passage through the trigger reactor means and the another heat exchange means,  proceeds to and through the first exchange means for passage to the collector and repetition of the just-described procedural sequence.  The storable material exiting from the another heat exchanger is of elevated temperature with a sensible heat content thereof available for usage, after storage or immediately, in manners known to the art for utilizing heated material in useful applications such as residential hot-water supplying and residential heating and cooling.

Abstract: ABSTRACT OF THE DISCLOSURE           In a fabricated rigid floor deck structure assembled from a plurality of similar floor sections, a floor section is formed for engagement with an adjacent similar section to form an interlocked floor structure.  Each floor section is constructed from an elongate plate having a male and a female flange each having a U-shaped cross section.  The female flange has one leg depending from one edge of the plate with its other leg positioned outwardly of the one edge to define an upwardly opening channel laterally outward from the plate.  The male flange has one leg depending from the opposite edge of the plate with its other leg positioned inwardly of the other edge adjacent the bottom surface of the plate.  The flanges are dimensioned so that adjacent floor sections are locked together in suitable alignment by placing the male flange into the channel defined by the female flange of an adjacent aligned floor section.  A plurality of elongate embossments are raised from the top surface of the plate and extend laterally across the plate to provide structural strength.          Openings are formed through the sides of the embossments in a plane generally perpendicular to the plane of the plate to permit air flow from one side of the plate to the other.

Abstract: ABSTRACT OF THE DISCLOSURE          Direct Memory Access Refresh System In a controller for a host machine such as an electrostatographic copier having a central processing unit module connected via a system bus to an input-output processing unit module, a direct memory access system functioning as part of the input-output processing unit module and operative to provide a high-speed means of refreshing and updating control registers in the host ma-chine by direct accessing of memory in the central process-ing unit module.  The direct memory access system may be programmed to synchronously refresh-update the host ma-chine's control registers as in its normal mode and also asynchronously refresh-update the control registers as in the abnormal mode of a detected electrical disturbance in the electro-sensitive periphery surrounding the control registers, thus requiring restoring thereof.  High-speed movement of data by the direct memory access system is achieved through dedicating a portion of random access memory in the central processing unit module for such access-ing, and transferring control of the system bus from the central processing unit module to the direct memory access system.  This enables data accessed through a fixed se-quence of addresses from dedicated memory to be transferred directly to the host machine's control registers without incurring time constants that would otherwise be had if the data were to be manipulated by a central processor in the central processing unit module
