Abstract: The method comprises spreading a layer of bituminous binding material on the surface, spreading at least one layer of aggregates on the layer of binding material, and compacting the layer of aggregates in contact with the layer of binding material. The aggregates consist of loose chips covered with a mixture, which has a pasty consistency, of bitumen and of pulverulent material. The layer of binding material contains at least 11% of the total quantity of bitumen used in the coating. The operations of spreading the binding material and the aggregates and of compacting and surfacing the coating are performed in succession within a period of less than 5 seconds, the speed of advance of the site being at least ten meters per minute. An integral mobile device carrying a bitumen-spraying boom and a finishing table fixed to the rear part of the chassis makes it possible to produce a coating according to the invention using aggregates which are coated with bitumen produced by the device or transported thereby to the rear part of the chassis between the spraying boom and the finishing table.

Title: Universal motor speed control circuit for hand mixer
Inventor: HOUST DOUGLAS RAYMON
IPC: H02P25/14
Filed: 1990-03-28
Granted: 1996-01-16
Abstract: A speed control circuit in combination with an electrical motor for use in a hand-held food mixer operated on AC household electrical current.  The motor is a universal type having a series connected armature winding and field winding wherein the field winding includes a plurality of taps each selectably connectable to the current source by a multipoint switch.  A          Quadrac? semiconductor switch containing a triac and triggering diac in one package conducts electrical current from the current source through the armature winding and the selected portion of said field winding over a portion of each cycle of the current source.  A trigger signal causes switching of the semiconductor switch at a predetermined phase angle relative to the voltage waveform of the current source.  An error signal of a magnitude proportional to motor speed and based on counter EMF of the motor is generated by the entirety of the field winding.  The error signal is summed with said trigger signal to vary the phase angle of the semiconductor switch to compensate for variations in load applied to the motor.
