Abstract: ABSTRACT     A mobile, self-contained, self-powered three stage apparatus is discosed for separating solids from a liquid.     Three stack separator pods are mounted over a housing on a mobile platform.  A plurality of hydrocyclones are readily mounted with respect to the separator pods to provide for separating the solids therewithin.  Each successive separator pod contains a greater number of smaller diameter hydrocyclone so as to enable the separation of smaller diameter of particles.          Each separator pod also includes degassing capabilities.  A plurality of holding tanks act as reservoirs for the fluid and solid mixture prior to and subsequent to each separator pod.  A system of internal weirs allows overflow of liquids from a holding tank containing cleaner mixture to a holding tank containing a greater proportion of solids, whereby liquid equilibrium is maintained within the system.

Abstract: ABSTRACT OF THE DISCLOSURE    An improved method for inhibiting corrosion of inter-nal structural members of reinforced concrete, such as the corrosion of reinforcing steel members in a concrete bridge deck or a concrete paved driving surface, due to salt mi-gration into the reinforced concrete.  In general, the method comprises applying an effective amount of a hydro-lyzable organo silicon compound to the surface of the re-inforced concrete to substantially cover the surface of the structure with the organo silicon, and contacting the re-sulting organo silicon coated surface, after a period of time effective to allow the organo silicon compound to mi-grate into the structure, with an effective amount of water to substantially wet the surface of the organo silicon impregnated structure.

Abstract: Abstract A programmable logic controller is disclosed which includes a plurality of input interfaces and a plurality of output interfaces for connection to industrial equipment such as automatic assembly equipment, textile machinery, materials handling equipment, and chemical processes. The input and output circuits can be randomly addressed as to their state through an eight bit bus, which connects in parallel with up to 16 groups of eight input and/output circuits.  The controller includes groups of timers which are each manually adjustable as to the timing operation and which are sequentially addressed each time a timing function is called for by the program.  The timers are designed to be cascaded in groups to virtually any number of timers.  The controller includes a scratch pad memory, half of which retains memory upon power failure and half of which does not.  The control of the controller by the operator is made more nearly foolproof by interlocking the operations of the control switches.  Three programming instructions are available which are conditional upon the data in the accumulator of the controller.

Abstract: ABSTRACT OF THE INVENTION         A system is disclosed for transforming a collimated beam of light, such as that generated by a laser, into a line scan or a raster image for projection onto a screen or other object.  The laser beam is directed at a rotating mirror having a plurality of facets disposed at equal circumferential intervals around the mirror axis of rotation.  The light reflected from the rotating mirror generates a first scanned reflected output beam.  A first reflecting surface is aligned to receive the first scanned re-flected output beam and generates a second scanned reflected out-put beam.  This second scanned reflected output beam passes through a first pivot vertex and is directed back onto the rotating mirror facets by a second reflecting surface to generate an angularly amplified output beam which scans a first plane.  The angularly amplified output beam is directed through a second pivot vertex and is then deflected through a second plane which is oriented perpendicular to the first plane.  The angularly amplified output beam which has been deflected through the first and second planes thereby projects a raster image on a screen.

Abstract: -13-                RCA 76,460 ABSTRACT OF THE DISCLOSURE In add-on alpha-mosaic character (teletext) decoders, the character signals pass through the limited bandwidth chroma channel of the TV receiver.  For certain color combinations and signal durations this reduces legibility and contrast due to pulse stretching and amplitude reduction.  The present invention determines if a pulse is less than a predetermined pulse width and has an amplitude difference with respect to a preceding pulse of less than a selected amount.  If both conditions are met, then a luminance signal pulse is generated to substitute for the original pulse, the generated pulse having a large amplitude difference with respect to the preceding  pulse for improved contrast.  If the generated pulse would exceed the white level or go below the black level, then a pulse of opposite polarity with respect to the first generated pulse is generated to cancel the first generated pulse but still result in a large amplitude difference with respect to the preceding pulse.

Abstract: ABSTRACT     An adjustable structure comprises two panels 24 carrying at adjacent edges respective members 11, 13, each having ribs 14 and grooves inter-engaging with one another after the fashion of gear teeth so that the members 11, 13, can roll relative to one another about respective axes parallel with the panel edges. Each member 11, 13, carries within a respective longitudinal passage 33 resilient spindle elements 35 disposed substantially coaxially with the member 11, 13, and resiliently displaceable, at least in part, transversely of said axis. The members 35 are held together by connecting links 46 providing hooks receiving respective resilient spindle elements 35 of the two members, slots 32 being formed in the members 11, 13, for passage of the links. The configuration of the links 46 and the spindle elements 35 is such that resilient displacement of spindle elements 35 transversely of their axes, towards one another, is necessary to apply the links to or detach the links from the spindle elements. The construction described allows quick and simple assembly of various adjustable structures incorporating such panels, whilst ensuring reliable interconnection of the panels and adjustment of the structure.

Abstract: TAP BRACKET OR THE LIKE     ABSTRACT OF THE DISCLOSURE     The invention contemplates a unitary cable-clamp fitting adapted for equipment or other connection to an overhead-suspension cable or messenger wire.  The fitting comprises two side panels integrally connected by a single bend establishing an initially acute angle between the side panels.  In a preferred form, the outer edge of each panel is characterized by an elongate flange bent inward and generally toward the opposite side panel, and the initial space between flanges is slightly less than the cable diameter to be accommodated, so that cable assembly and loose retention are achieved via snap-action insertion between the flanges.  A nut and bolt, loosely engaged via aligned openings in the panels, is tightened to set the clamp to the cable.

Abstract: ABSTRACT OF THE DISCLOSURE          An analog carrier signal and its sidebands contain modulated information which is to be digitally encoded and processed.  Demodulation and digital encoding is accomplished in a single process by an analog-to-digital converter, which samples the analog signals in response to a sampling signal of a frequency which is less than twice the frequency of the highest frequency in the carrier and sidebands, but is at least twice the bandwidth of the band of frequencies containing the carrier signal and its information-bearing sidebands. The analog signal samples are digitally encoded, producing digital information signals corresponding to baseband signal components.        When used in a television receiver to produce digital signal samples, the band of analog signals may include both sound and picture carriers and their audio and video information.  By controlling the phase and frequency of the analog carrier signal in relation to the color subcarrier signal, and deriving the sampling signal from the analog carrier, an ease in video signal demodulation is provided.
