Abstract: Abstract Of The Disclosure A system for forming flat base truck rims from flat strips of steel rolled into the form of smooth cylinders and welded together along the abutting axial edges. The system is capable of forming rims from hot rolled, rimmed, low carbon steel strips. The smooth cylinder is initially formed by a plurality of dies located at opposite ends of the cylinder and mounted for advancing movement relatively toward each other in the direction of the cylinder axis to flare a first end of the cylinder radially outwardly while rough forming a rim gutter on the other end of the cylinder. The radial thickness of the metal forming the rim gutter is increased during the rough forming thereof by applying a compressive axial load to the cylinder and providing a gutter-forming die cavity wider than the starting thickness of the cylinder. The rim gutter is warm or hot formed by heating that end of the cylinder before advancing the dies to roughly form the gutter.          The flaring step is performed with an expandable die which is expanded during the flaring step and then collapsed and advanced to deform the outwardly flared portion of the cylinder to rough form a fixed flange, so that different portions of the same die are used to effect both the flaring and the flange forming. The flat base of the rim is shear formed to reduce the radial thickness thereof in the low stress area between the gutter and the fixed flange. The final profile in the fixed flange and the gutter is produced by roll forming the rim.

Abstract: Abstract of the Disclosure A rotary brush includes a generally cylindri-cal, sheet metal core having fittings arranged to be inserted into both ends thereof for the reception of conventional brush drive means, e.g., a rotating drive shaft adapted to extend through the core or stub shafts which are adapted to extend only into the ends of the core.  The fittings are comprised of an elastomeric material having a Shore scale A hardness within the range of from about 85-100, and the tubular core is provided with radially inwardly extending circumferentially spaced projections adjacent each end thereof which are adapted to slidably fit within axially extending grooves formed in the outer surface of the fitting and to resiliently engage the fitting to thus lock the fitting against relative rotation.  The fittings, which are adapted to be snugly and resiliently secured to the aforementioned brush drive means, may be readily replaced when desired simply by sliding them out of the ends of the core.                       -1a-

Abstract: Abstract A chart recorder is disclosed  having a variable chart speed and a writing device in the form of a variable droplet rate ink jet pen.  The signal pulses for ejecting ink droplets from the pen are generated by a voltage controlled oscillator, and circuits are provided to make the oscillator output frequency proportional to the chart speed, and also responsive to higher rates of pen movement, so that a substantially uniform density line is traced at all chart speeds and virtually all rates of pen movement.  To simplify the circuit while maintaining an extremely wide range of writing speeds, the voltage sweep range of the oscillator is set at the upper end of the pen response frequency, and lower oscillator output rates are established by selectable R-C circuit components to match the speed of the chart recorder.          To give more precision, a circuit embodiment is alos disclosed that generates pen control pulses proportional to the true rate of relative movement between the pen and the chart.  The application of the latter circuit to an X-Y recorder is also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE             DIGITAL PHASE AND FREQUENCY METER           Phases are measured with a resolution of one degree, and frequencies are measured with a resolution of 0.01 Hz by the same circuitry.  An internal voltage-controlled oscillator (VCO) is forced to operate at 360 times the frequency of the incoming test signal by use of a phase-locked loop and a 360 divider.  Clock pulses from the VCO are counted throughout an interval of noncoincidence of the original test signal and any phase-shifted version of that test signal, and the count is digitally displayed directly as phase shift in degrees.  Clock pulses from the VCO are counted throughout an interval of (1/3.6) second and the resulting count is digitally displayed with the last two digits marked off by a decimal point, as the frequency.
