Abstract: An apparatus and method for fragmenting and re-mixing agglomerated pieces of rubberized asphalt prior to applying same to a road surface. Agglomerated pieces and rubberized asphalt material are delivered to the upper portion of a housing. In a first embodiment, an auger and tine assembly having a common drive shaft, is mounted for rotation within the housing. The assembly includes first and second auger sections, mounted along the shaft in spaced relation and having converging, opposite handedness. A rotating tine section is positioned between the auger sections. A fixed tine section is mounted in the housing in interdigitized relation with the rotating tine section. In a second embodiment, the entire drive shaft includes a rotating tine section, and a corresponding interdigitized fixed tine section is provided within the housing. Passing through apertures defined by the fixed and rotating tine sections, agglomerated pieces are fragmented and re-mixed with the other material.

Abstract: An apparatus and a method for re-mixing size and weight segregated Hot Mix Asphalt (“HMA”) which is continuously discharging from a windrow elevator. The apparatus includes an auger assembly having first and second helical auger sections, mounted in spaced relation over respective ends of an auger connecting shaft. The first and second sections are of converging, opposite handedness. Owing to their orientation and handedness, the augers advance incoming material inwardly, toward a mixing zone, adjacent and around an intermediate portion of the connecting shaft. The apparatus also includes an auger housing, having an upper portion with a material inlet, and a lower portion with a material discharge. The auger assembly is mounted for rotation within the lower portion of the auger housing. The housing surrounds side, bottom and end portions of the auger sections. The material inlet is above and in communication with upper portions of the auger sections and the mixing zone.

Abstract: An exercise machine utilizes a mechanical brake to provide the principal resistance. A dynamoelectric machine has its rotor connected to the flywheel of the exercise machine and its stator rotatably mounted to the apparatus frame and connected to the actuation input of the mechanical brake. The torque applied between the rotor and stator of the dynamoelectric machine tends to turn the stator and thus actuates the mechanical brake. A control system is arranged to control the current flow through the dynamoelectric machine and thereby control actuation of the brake. This allows a small dynamoelectric machine to effectively control a very large resistance. The dynamoelectric machine may also be used as a motor to drive the apparatus. Thus, the control system can actuate the dynamoelectric machine either to apply drag or to drive the apparatus thereby provided through constant speed operation.

Abstract: A muscle exercise and rahabilitation apparatus includes a movable fixture against which a force can be applied; a servo motor having an output shaft coupled to the fixture; a strain gauge effectively coupled between the output shaft and the fixture for producing a load signal corresponding to the force applied to the fixture; a speed detector for producing a velocity signal corresponding to the speed of the fixture; a closed loop servo circuit for controlling the motor in response to the load and velocity signals to regulate the velocity of the fixture; a limit circuit for preventing movement of the fixture past opposite limits; a storage circuit for storing limit signals corresponding to each limit; a limit setting circuit for enabling the storage circuit to store each limit upon movement of the fixture thereto; a position sensing circuit for producing a position signal corresponding to the position of the fixture; a deceleration circuit for slowing down movement of the fixture as the fixture approaches each

Abstract: The present invention relates to an electrical circuit for current regulation in DC motors including a sensitivity control means therefor. The circuit includes a means for sensing a predetermined current level in the load of a DC motor. In combination therewith is a subcircuit for cutting-off the load current when the predetermined current level has been reached. Additionally, there is provided means for restoring the load current when, after load current cutoff, the inductive motor current has fallen to a level sufficient to restart the subcircuit.

Abstract: The present invention constitutes an electrical mounting and conduction means having a support element having a generally U-shaped interior surface, the base of the exterior of the support element being in thermal contact with a heat dissipating surface; a carrier element having a generally U-shaped exteriorsurface, the surface having a cross-section of smaller dimension than that of the U-shaped surface of the support element, the carrier element being nestable within the support element; and locking means removably securable to adjacent arm members of each of the support and carrier elements for maintaining the support and carrier elements in selective securement to each other.
