Abstract: This disclosure generally relates to a technique and apparatus for solar heating which may be adapted for heating residential, commercial or industrial buildings, and in which the functions of solar energy collection, storage and heat-exchange are combined in the same passive structure generally consisting of a plurality of cylindrical tubes preferably fabricated of glass-fiber reinforced polyester resin which are filled with a stationary heat absorbing medium, such as water, with their surfaces preferably coated with a high absorbtance material on to which solar rays are directed through a solar "transmittor" or window, and which surfaces serve as heat-exchange elements from which heat may be extracted in a variety of ways, including passage of air and thermal siphoning, and with the tubes enclosed within an appropriate insulated chamber. Cooperative action with domestic or similar hot water systems may also be achieved.

Abstract: The invention is concerned with training fish, such as salmonoids and other varieties exhibiting similar growth habits and characteristics, to live and feed in concentrated vertical stacks under light-blocking covers contacting the water (floating upon or submerged, partly or totally), such that the fish need not be contained by nets, walls or other barriers in the sea or other water bodies; and then may be harvested or otherwise collected or even transported, when desired, by enclosing or sweeping the dark areas under the covers by nets or cages or the like, or transporting the covers, with the fish moving to stay in the dark areas thereunder, to an enclosed, netted or otherwise barriered area.

Abstract: This disclosure is concerned with simplification of customer TV decoders for scrambled television signals fed from a master antenna system or the like, by novel head-end decoding and simultaneous scrambled STV transmission along the distribution cable to the user TV sets.

Abstract: A process is disclosed for enhancing the speed of both certain black and white and color films, through initial black-and-white development, and redevelopment with color coupling developers and color coupling dye units, and replacement of silver units with multiple color dye units for each silver unit that provide a color image enhanced over that provided by the silver image.

Abstract: This disclosure is concerned with a process for connecting a short detector to electrical nodes in such apparatus as backplanes, cables, and circuit boards, before and after component assembly, to identify shorted node pairs in a substantially smaller number of tests than required by previously known methods, through a novel series of tests between each node and all other nodes, taken together, so as to identify shorted nodes, and then a series of tests between each of these shorted nodes and all other shorted nodes, taken individually, to identify the shorted node pairs.

Abstract: This disclosure is concerned with a new technique for automatically measuring impedance (though the process is also applicable to other parameters and characteristics as well) wherein a series of voltages are sequentially presented to a common detector and analog-to-digital converter, the numerical values of which voltages are of themselves meaningless, but from which, with the aid of microprocessor calculating equipment, ratios may be calculated that indicate impedance (or other parameters).

Abstract: This disclosure is concerned with a tannery primary treatment process that, in total combination, or as separate sub-process features, enables the reducing of BOD loading in such treatment, while increasing the efficiency of hexavalent chrome recovery therefrom by separating out alkaline sulfide solids from the normal unhairing beamhouse stage and utilizing the same to attain appropriate sedimentation tank sludge pH for oxidation of the chrome to the hexavalent state during incineration; and/or increasing the hexavalent chrome recovery by backwetting and roasting the ash again; and/or enabling use of such ash for recycling as a chrome tanning liquor with the side-production of an improved flocculating chrome water wash for waste treatment use.

Abstract: This disclosure is concerned with apparatus for enabling extension or other leveling adjustment of manhole cover supporting structures and the like comprising extension spacer rings resiliently compressed in self-storing fashion adjacent a support sleeve portion of the supporting structure, and adapted to be forced downward from storage to expand into position below the sleeve to extend or adjust the level of the same.

Abstract: This disclosure is concerned with improvements in underwater elapsed time strobe-camera apparatus and the like involving sonar-triggering by a sonar beam generated co-axially with and about the camera lens axis and, as a result of novel circuits, size-reduction and packaging, adaptability for portability, with ancillary novel features of automatic predetermination of number of pictures and indication thereof.

Abstract: This disclosure is concerned with a process of and apparatus for producing relatively low energy electron beams through pulsed cold-cathode beam generation in a mode of operation involving an important intermediate region of a substantially linear depth-dose profile characteristic that reduces the sensitivity to possible voltage variations, and with improved triggering structures that significantly improve reliability and minimize erratic pulse generation and missing pulses, thus particularly adapting the process and apparatus for such stringent applications as production-line sterilization of surfaces, materials or workpieces passed by the apparatus.

Abstract: This disclosure is concerned with a motor technique for generating speeds that are fractions of synchronous speeds, through novel time-staggered selected half-cycle energization of a plurality of magnetic poles by a controlled switching sequence, generating such a fractional motor speed that would otherwise have to be produced by a much larger number of magnetic poles.

Abstract: This disclosure is concerned with the more efficient utilization of fish feed, such as the pelletized feed for salmonoids and the like, introduced into pluralities of ponds, through appropriate bottom funneling of uneaten feed and waste water and utilization of the exiting waste water to carry the uneaten feed for injection into a next pool after separation from the carrying waste water; the process being applicable to any type of pond, but particularly suitable for ponds in which dark rest areas are provided for accelerated growth.
