Abstract: A cathodic protection system and method for steel reinforcement in concrete structures such as bridge decks, parking garage decks and highways utilizes platinized niobium or like metal wire anodes strategically positioned adjacent the concrete in a matrix of conductive carbonaceous material. The anode and matrix are preferably positioned in slots saw cut in the concrete surface avoiding the disposition of a conductive and wear resistant surface overlay which is not only expensive but which may exceed the design limitations of the structure. An impressed protective cathodic protection current is provided between the anodes and the steel of the structure. At places where the anode crosses in close proximity to reinforcing steel which may be exposed by the slot, or at places where cathodic protection current is not desired, a plastic sleeve may be placed over the anode.

Abstract: An encoder for manually or automatically providing a sequence of identifier signals and a decoder for same, in a remote dictation system. A pair of control lines (10, 10' and 11, 11') carry the identifier signals which are in part identical to signals used to control dictation recording functions of the remote recorder. A sequential counter (31) and a matrix of switches (32) provide an automatic sequence of signals to a set of transistors (15-18) and diodes (19, 20, 22) which establish the control line voltages. These devices are alternately connected (70-75) to shift registers (61, 62) which accept keyboard signals entered from a keyboard (60). Timing circuitry (65, 66, 68, 69, 99, 117) controls the shifting of keyboard signals in and out of the registers. A combination of comparators (150-153) and gates (170, 171) decode the control line voltages and provide inputs to decoding (169, 172, 176) and timing (191, 195) circuitry which provides a binary number to a memory device (250).

Abstract: Poultry gizzards with entrails such as gut and stomach attached are supported at first on a rotary drum with a helical tread and a rotary support bar whereupon the gizzards are urged along a path and are oriented so that the entrails hang therebelow as they move along the path. As the gizzards move beyond the rotary drum they move onto a stationary support bar that also cooperates with an extension of the rotary support bar, and a conveyor moves down into engagement with the gizzards and urges the gizzards further along the path. A rotary cutting disc extending over the support bars severs the entrails from the gizzards, and a second rotary cutting disc protrudes upwardly between the support bars and splits the gizzards. The split gizzards then straddle a support rail and move up on and over helical cleaning wheels which further separates the cut-apart portions of the gizzards to permit water spray to remove the particles from the gizzards.

Abstract: Self-erecting apparatus for transporting and temporarily storing material such as asphalt; the apparatus includes a surge bin and a drag chute for transporting the asphalt material from a drum plant to the surge bin. The drag chute and the surge bin are pivotally attached to each other and to a flat bed trailer, permitting their simultaneous raising and lowering by means of a winch apparatus attached by means of cables to the support legs of the surge bin to provide ease of lowering the bin for transportation of the apparatus from one site to another and ease in erecting the bin at a new site. A foldable side panel of the surge bin permits the drag chute to nest in the surge bin thus providing a more compact arrangement of the apparatus when in the lowered configuration.

Abstract: A dictation-transcription method and system in which dictated material and instructions concerning the dictated material for use during the transcribing of the dictated material are separately recorded on a recording medium along with indexing signals which include indexing signals identifying the location on the recording medium of the separately recorded instructions concerning dictated material. The recording system and method permit the recording of instructions at any location on the recording medium relative to the dictated material including a location along the length of a recording medium which is the same as the location of the dictated material to which an instruction relates without obliterating any of the dictated material, while at the same time preventing the inadvertent placing of the recording system in a recording mode of operation following the recording of an instruction which would cause dictated material to be inadvertently obliterated.
