  • Patent number: 4503578
    Abstract: A brush assembly for cleaning the bore of a cannon. The assembly includes a cylindrically-shaped brush (46) supported on front and rear plates (22, 24). An assembly shaft (30) extends through the plate, the center of the brush and through the rear plate. A threaded collar (36) is connected to the rear of the assembly shaft for receiving a ramming shaft (42). A conically-shaped centering element (58) is disposed over the threaded collar and is provided with an opening for accommodating the ramming shaft. The centering element realigns the brush with the bore thereby permitting the brush assembly to be pulled back through the barrel (72) without the necessity of manually recentering the assembly with the bore.

  • Patent number: 4500879
    Abstract: A CRT beam control apparatus wherein a microprocessor drives the CRT beam for controlling the beam characteristics, including writing speed, slope, position and intensity. The apparatus includes a single digital-to-analog converter supplying sample-and-hold circuitry through a selector and further includes a pair of active integrator circuits switchable to connect the output of the digital-to-analog converter or sample-and-hold circuits. The microprocessor is operative to provide digital words to the DAC representative of the differential X and Y values of a line segment to be drawn. The analog representations of these digital words are coupled to the integrators. The outputs of the active integrators provide the deflection signals causing deflection of the CRT beam. The apparatus is particularly adapted to drawing a series of connected line segments, due to the integrator operation.

  • Patent number: 4494232
    Abstract: A statistical multiplexer is disclosed that includes interfaces for asynchronous and synchronous data equipment, and a CPU/control logic. The CPU/control logic cooperates with the interface for the synchronous data equipment for allocating bandwidth to synchronous data equipment when bandwidth is requested and for deallocating bandwidth when bandwidth is no longer required. The allocation and deallocation of bandwidth is controlled by predetermined control frames generated by the CPU/control logic. Such control frames are responded to by the synchronous data equipment interface of the multiplexer originating the control frame and the synchronous data equipment interface of the multiplexer receiving control frames.

  • Patent number: 4491827
    Abstract: The present invention provides a preset counter apparatus for a copying machine wherein input keys are capable of independently controlling the numerical value of the number of copies to be made and displayed. Thus, an operator can activate one key to change the digit positions of units and another key to change the digit position of tens. The control of the number of copies to be made is specifically designed to facilitate operator use and to avoid operator errors. Simultaneous activation of more than one key prevents any change in any values in both the units and tens positions.
