Abstract: BULLDOZER BLADE ANGLE SLIDE MECHANISM                       Abstract An angled bulldozer blade for an earthmoving machine is operatively connected to a slider assembly slidably carried on a rail fastened to each side arm of a C-frame.  Removable pins engage with each slider assembly and pass into aligned apertures of a plurality of prelocated apertures in the rail to position the slider assembly for setting the blade in a desired angled position. Self-locking latches are provided for retaining the pins in position.  Eight apertures in each side rail are located so as to provide five positions for the slider assembly.  In prior devices of this type the use of a single pin to lock the slider assembly made it difficult to readjust the blade angle because of pressure created on the pin.  By positioning a pin at each end of the slider assembly one of the pins will always have substan-tially no load for easy removal.

Abstract: METHOD OF CONTROLLING A HEATING FURNACE FOR                STEEL INGOTS               ABSTRACT OF THE DISCLOSURE         A method  of controlling a heating furnace for steel ingots, particularly a soaking pit for steel ingots, which is charged with a basic fuel quantity for heating the ingots to rolling temperature.  The surface temperature of the ingots and thermal data of the furnace are measured and heat balances are established.  From the resulting furnace balance temperatures, together with the surface temperature of the ingots, an estimated value for the center temperature of the ingots is determined in an estimating device.  The estimated ingot center temperature and the ingot surface temperature as actual temperatures are com-pared with predetermined ingot core and surface temperatures as nominal temperatures.  The resulting difference is used to correct the basic fuel quantity fed to the furnace. The surface temperature of each individual ingot in a furnace may be measured.  The correction of the basic fuel quantity may be started after an empirically determined time interval of ingot heating in the furnace, and may be 1/4 to 1/3 of the total required pit time, which is the time between charging and drawing of ingots from the pit. During the pit time, ingots are heated in the soaking pit.

Abstract: METHOD AND MEANS FOR SEGMENTALLY REDUCING               HEAT OUTPUT IN A HEAT-TRACING PIPE                    ABSTRACT OF THE DISCLOSURE  This invention relates to an improvement in a heat-generating pipe made up of a ferromagnetic pipe having an insulated conductor extending through it to a given point so that both the pipe and conductor may be connected in series with a power source of alternating current.  The invention is directed to both a method and means for reducing the heat output over a desired segment of the pipe by reducing the magnetic field created by the alternating current flowing in the insulated conductor and that segment of the pipe.  The means may be:  a second electrical conductor internal and parallel to the heat reduced segment; a segment of nonferro-magnetic electrically conductive pipe; an electrically noncon-ductive pipe extending throughout the desired segment shunted by a second conductor; or a portion of the insulated conductor that is exterior to the ferromagnetic pipe along the segment so that it is magnetically decoupled from the pipe in which a reduced heat output is desired.  The method comprises the requisite steps of connecting an electromagnetic field-decreasing means in the series circuit to reduce the alternating magnetic field produced in the pipe by the alter-nating current flowing through the conductor inside the pipe.

Abstract: - i -ABSTRACT OF THE DISCLOSURE         A sleeve member interconnects an upper and lower length of replacement casing, which lengths are associated with the vehicle speedometer and transmission respectively.          The upper length is crimped into one end of the sleeve member while the lower length is slidably adjustable within the remaining portion thereof.  By a series of process steps, the interconnected lengths of replacement casing will contain a replacement rotatable flexible shaft cable therein, which cable is provided with a square tipped cable fitting at each end thereof, one of which operatively engages the vehicle speedometer while the other engages the transmission.          By virtue of the slidably adjustable lower casing length within the sleeve member, proper protrusion of the cable fitting square tips is insured.  The adjustable length of casing may then be rigidly crimped into the sleeve member.          Thus, no preformed square ends are required on the replace-ment cable and yet the process permits the use of replacement casing material having an inside diameter no larger than that of the original equipment casing, the latter feature providing a quietly operating aftermarket device.

Abstract: ABSTRACT OF THE DISCLOSURE           A high-voltage, blast-actuated power switch is disclosed in which field electrodes are included in order to prevent arcing within the switch after a bridge conductor has been blasted.  The field electrodes are arranged coaxially about the bridge conductor, and are each electrically connected to one of     two external connections.  The field electrodes include opposing ends which are rounded and which are separated from each other by a distance which is smaller than the distance between the separated ends of the bridge conductor that  are bent back onto internal elements of the external connections when the bridge conductor is blasted.  The field electrodes tend to reduce the influence of the sharp edges formed on the separated ends of the bridge conductor when the bridge conductor is blasted, thereby increasing the breakdown voltage between the external connections and increasing the dielectric strength of the switch.  An alternate embodiment of the present invention includes a floating electrode which is arranged between the opposing ends of the field electrodes.

Abstract: ABSTRACT OF THE DISCLOSURE      A hardware/firmware communication line adapter for inter-facing a communication processor to a broadband high level data link communication channel.  Transmit and receive data and control characters received either from the processor or from a communication channel device are processed under the control of the adapter firmware to effectuate CRC checking, byte size control, extended and variable field format control, partial last byte control, and block transfer control functions on the transmitted/received data stream.  First-in-first-out (FIFO) buffer memories are employed in the transmit circiuts to queue a frame of transmit data and control characters at the adapter whereby the communication processor/adapter interface control is simplified.  Similarly, a FIFO buffer is employed in the receive circuits to reduce the frequency of receive interrupts and to enable block transfer of received data to the processor.
