Abstract: ABSTRACT        An elongated tubular ground anchor having a leading driving end with an internal impact receiving abutment and a tapered out-turned trailing end has an external cable swingably secured thereto about midway between said ends but rearwardly of the, center of mass of the anchor, is guided and driven lengthwise into the ground to a desired depth by a ram entering the trailing end and impacting the abutment with the cable ex-tending above ground from the hole in the ground formed by the anchor and driving ram. The cable is pulled or tensioned causing the trailing end of the anchor to plow into the ground forming a fulcrum to rotate or tilt the anchor from its upright driving position to an inclined position transversely of the hole and with the leading end remaining lower than the trailing end.          The driving ram may be hollow and a concrete slurry pumped through the ram as it is retracted from the anchor and hole to fill the hole with the cable surrounded by the slurry. A plug may then be pressed into the hole to compress the concrete slurry causing it to flow into crevices and pores of the ground surrounding the hole and concrete may then be poured into the hole above the plug while the cable is held under tension. After the concrete sets, a tensioned cable reinforced column of con-crete fills the hole and cooperates with the anchor to provide a firmly secured ground anchored cable. The cable anchor may be further strengthened by swaging an entrance hole of larger diameter than the hole formed by driving the anchor in the -i-ground but only extending to a depth substantially less than the depth to which the anchor is driven. This large diameter entrance hole is thereby surrounded by compacted earth due to the swaging operation and may be lined with a tube to keep the hole in an open condition during the driving of the anchor. The liner is withdrawn and the entrance hole is also filled with concrete which is pressed by the plug thus forming a concrete column interlocked with the ground and embedding the anchor and cable.                -ii-

Contaminated solvent is drained from the sink into one side of the tank and recirculated to the sink by a pump on the opposite side of the tank, heavier contaminants falling to the bottom of the tank away from the pump to avoid clogging of the pump.  A multi-partition filter assembly surrounds the pump.  The sink includes an overflow pipe, an aeration system for agitating the parts being cleaned, a removable parts basket which may be suspended from the side of the tank to dry and a safety cover which closes in the event of a fire.  A normally open valve having a fusible link operator shuts down the aeration system in the event of fire.

Abstract: SENSE POINT CIRCUIT          ABSTRACT OF THE DISCLOSURE          The disclosure relates to a sense point circuit for sensing the active or inactive condition of an electrical path as represented by the conduction or nonconduction of a solid state device in response to an interrogating signal pulse.  The sense point circuit comprises an input for receiving the interro-gating signal pulses, a solid state switch such as a transistor, and a transformer having a primary coupled across the base and emitter of the transistor and a secondary coupled across the solid state device and an output coupled to the emitter of the transistor.  The sense point circuit additionally includes a first re-sistor coupled between the input and the common junc-tion of the base of the transistor and the transformer primary, and a second resistor coupled between the input of the sense point circuit and the collector of the transistor.  When the solid state device is con-ductive, the primary winding of the transformer pro-vides a substantially short circuit across the base and the emitter of the transistor, to thereby cause the transistor to be nonconductive upon the receipt of an interrogating pulse so that the interrogating pulse is conducted from the input to the output through the first resistor and the transformer primary.  When the solid state device is nonconductive, the primary pro-vides a substantially open circuit between the tran-sistor base and emitter to thereby cause the transistor to conduct upon receipt of an interrogating pulse so that the interrogating pulse is conducted from the input to the output through the second resistor and the transistor for providing a second signal.  Be-cause the first resistor has a resistance greater in magnitude than the second resistor, the first signal magnitude is substantially less than the second signal magnitude.

Abstract: ABSTRACT OF DISCLOSURE      During passage of an I-beam through a punching press for punching holes vertically through its web, holes are also punched through its flanges by horizontally acting punches of the present invention.  Four C-shaped punching heads are pro-vided for the flanges.  To permit punching closely adjacent holes, two punches are powered by a single hydraulic cylinder, unless one is deactivated.  A joint gauge screw precisely adjusts gauge (the spacing between the two punches), and may be raised or lowered for centering as to web.  Before each flange punching operation, the web is pressed firmly against a fixed block level with the web die.  The piston of the hydraulic cylinder is of such large diameter that the varying positions of the punches will lie within the projected periphery of the piston rod.

Abstract: ENGINE SPEED AND DIRECTION CONTROL               Abstract of the Disclosure An engine control wherein a shaft driven by the engine causes a first signal to be generated and then a second signal after the shaft has rotated through a pre-determined degree.  The first signal starts a timer into operation, the timer producing a timer pulse of predeter-mined duration.  Time coincidence of the timer signal and second signal indicates that a critical engine speed has been reached and such time coincidence is used to effect a control function.  If the shaft rotates in the opposite direction the sequence of generation of the first and second signals in such direction is detected and used to generate a reverse-direction signal which is used to effect a control function.  An automatic impedance-changing circuit enables the control to be used with a wide range of batteries.

Abstract: PHD.77-029 ABSTRACT:          In electronic computer systems peripheral units are generally connected in series to the central processing unit via a common data bus. Via the data bus the data signals of one specific sign and, as the case may be, control signals are each time trans-mitted with a parallel clock signal, whose instant of appearance indicates when the other signals are valid.          All signals in each peripheral unit pass through the same number of circuit elements, in particular regene-ration amplifiers and logic circuits, a plurality of circuit elements being each time combined in one inte-grated semiconductor circuit, which may exhibit diffe-rent propagation delays. In order to ensure that also in a longer chain of peripheral units the clock sig-nal neither appears before the data signal with the greatest delay nor unnecessarily later so as to obtain the maximum transmission speed, the clock signal in each peripheral unit is in addition passed in parallel through all integrated semiconductor circuits and at the output of said circuits combined in such a way that the active state does not appear prior to said state at the output of the semiconductor circuit, or semiconductor circuits, with the greatest delay. Thus, the clock signal is always delayed to at least the same extent as the data signal with the greatest delay, for which some additional circuit elements must be included in each peripheral unit.

Abstract: BAR CODE CONVERTER            ABSTRACT OF THE DISCLOSURE         Bar codes imprinted or otherwise applied to an object are read and decoded by focusing light reflected from the code by means of an object lens to a light responsive transducer.       Electrical signals produced by the transducer are correlated and converted from a trinary code format into a binary code format.  The trinary code utilizes bars and half bars made up of segments in one or more of four quadrants to represent a decimal equivalent number.  This trinary code is applied to a converter where logic converts the trinary signals into equiva-lent binary signals which are then translated from a serial format into a parallel format for further processing by con-ventional binary code processors.
