Abstract: ABSTRACT             An input converter circuit for producing a logic level indication of the on of off condition of an input.  The input may be AC or DC at any reasonable level.  A bilateral photo-coupler output is applied to an operational amplifier integrator, which establishes the integration time of the signal.  The amplifier output is coupled to a Schmitt trigger having threshold levels at about one third and two thirds of the power supply voltage.  The output of the Schmitt trigger provides a logic one output if there is an input signal present and a logic zero output otherwise.

Abstract: FAULT INDICATOR AND MEANS FOR RESETTING THE SAME Abstract of the Disclosure A fault indicator for alternating current distribu-tion systems includes a pair of spaced pole pieces for receiv-ing therebetween at one end the conductor and at the other end a pivoted permanent magnet carrying a target that is biased to a fault indicating position by a stationary permanent magnet. The pole pieces are demagnetized on flow of fault current in the conductor. They are remagnetized by a winding which is energized by discharge of a capacitor that is charged through a rectifier from an oscillator circuit. The winding is carried by a receptacle into which the other ends of the pole pieces are inserted and a circuit is completed thereby to charge the capacitor. The receptacle is carried at one end of a tubular housing the other end of which has an eye to receive a claw of a live line tool for applying the fault indicator to and removing it from the conductor.

Preferably, the gases are those which are relatively inert or not unduly reactive and which possess relatively low saturation levels with respect to the liquid. Desirably, the gas is added through a member to the flow conduit in a vicinity of high turbulence. The surge suppression system can be utilized in generally any liquid system and particularly in a liquid transmission system.             Another embodiment pertains to a scrubber or washer for generally purifying gases and may contain one or two stages to efficient-ly remove impurities as through the use of high solubility fluids, fluids which decompose contaminants or which contain or provide (i.e. heating stage) catalysts to decompose contaminants, oxidizing agents, or re-ducing agents. The scrubber contains a packed bed and the packing may be characterized as one where the inside hydraulic radius equals the hydraulic radius of the external flow channels. The washer or scrubber type apparatus is particularly suitable for treating (purifying) materials such as ozone utilized in a deodorizing or disinfecting system.

Abstract: BI-DIRECTIONAL, SELF IMAGING GRATING DETECTION APPARATUS                     Abstract An optical position sensing apparatus utilizing a grating having two sets of opaque and transparent lines thereon, one of the sets being off-set from the other is associated with a source-detector assembly, the source and detector assembly including pairs of light sources and detection devices with at least one of the devices of one of the pairs being aligned with one set of light interrupting opaque lines and the other device of the pair being aligned with the other set of light interrupting opaque lines so that the image of the area illumi-nated by the opposing source is projected back upon the area of the grating in front of its respective detector as by an imaging reflect surface, preferably a concave mirror.   Inasmuch as the illuminated areas are of the same phase, the projected images will also be of a similar phase.  The grating lines in front of the detectors, however, are 90° off-set due to the off-set of the grating lines.  This causes the output signal from the detectors to have a phase relation which will permit direction sensing as to the movement of, for example, the carrier in an ink jet printer.

Abstract: Seals for the edge of a pivoted blade are provided in which an elongated strip of rigid material of U-shaped cross-section having side walls the interior of at least one of which carries resilient teeth pointed toward the closed portion of the U, and the open end of the U is narrowed to enhance the grip of the seal on the edge of a blade.  The preferred sealing expedient employs a flap which extends to one side of the strip and which is dimensioned so that it does not reach the free end of the adjacent side wall.  In one form of the seal, the side wall opposite the flap is extended to lock with a bend on the edge of the blade.  In a damper, the seal is mounted on the edge remote from the air flow into the damper so that the flap is biased against the adjoining blade and the air pressure serves to strengthen the seal.

Abstract: ABSTRACT OF THE DISCLOSURE          Method for introducing deoxy-desulphurizing substances into liquid metal without the use of gaseous carrier.  The invention refers to the elimination of sulphur and/or oxygen obtained in metal baths and to control the nature and form of the sulphur and oxygen compounds produced as results of deoxy-desulphurizing treatment.  A further object of the invention is to eliminate the sulphur compounds from slag as volatile compounds in order to avoid the sulphur to be transferred back to the bath from the slag owing to the oxidizing effect of the air.  The invention is based on the principle of adding the active substances to the bath through a special hollow carrier wherein they are contained in discrete quantities separated by inert materials.  The inert material can be metal sheet, sponge metal or metal powder and the metal can be iron.  The inert material can also take the form of other compounds, e.g. inert oxides, especially alumina. Mixtures of alkali and/or alkaline earth halides and oxides of the same elements are particularly useful for the desulphurization of the whole system slag/metal by means of sulphur and halide volatile compounds.

Abstract: ABSTRACT The pneumatic tire incorporates a reinforcement belt comprising two superposed unfolded median plies and two laterally disposed folded marginal plies. The folded plies each form two superposed flaps, with the corresponding flaps of each marginal ply being substantially aligned.          In all embodiments of the invention at least one pair of corresponding opposite laterally disposed flaps align with one of the unfolded median plies, and the lateral areas of the other unfolded median ply are surrounded by the folded plies.          In at least one embodiment of the invention the unfolded ply that aligns with one pair of oppositely disposed flaps is radially internal of the other unfolded ply. In another embodiment the aligned unfolded ply and flaps are radially external of the other unfolded ply.          The superposed flaps of each folded ply differ in cross-wise extent. In at least one embodiment of the invention the corresponding flaps of greater crosswise extent are radially external to those corresponding flaps of lesser crosswise extent. In another embodiment of the invention the corresponding flaps of greater crosswise extent are disposed radially internal to those corres-ponding flaps of lesser crosswise extent. In all embodiments of the invention there are at least two and at the most three layers of ply material at various points along the crosswise width of the reinforcement belt.

Abstract: LIQUID PUMP WITH GAS SEPARATING MEANS                    ABSTRACT OF THE DISCLOSURE           A gasoline pump includes a cyclone air separator by which air is removed from the gasoline being pumped. The air is vented to the atmosphere through a vent chamber. The cyclone separator includes a scavenging tube for capturing the air bubbles and is coupled to an orifice between the separator and the vent chamber.  The scavenging tube and orifice have diameters selected to capture sub-stantially all of the air bubbles and a float valve couples the vent chamber to the pump inlet to return entrained gasoline to the pump.  A damped output control valve regulates the internal pump pressure so the cone of air bubbles formed in the cyclone separator remains relatively constant and is efficiently captured by the scavenger tube.
