Title: Traffic monitoring device
Inventor: KNISCH KONRAD
IPC: G08G1/054
Filed: 1988-04-08
Granted: 1991-10-08
Abstract: Abstract Traffic Monitoring Device With  a  traffic  monitoring   device  for  photographic recording  of vehicles exceeding a predetermined  speed, the  speed  of  the   approaching  traffic  is  measured substantially  against  the  travelling  direction.  The vehicles  (12)  are  photgraphed   frontally  when  they exceed  the predetermined speed. Two speed  measurements are  effected:  A first mesuring value is obtained in  a relatively  short  part   of   the  available  measuring section  (22) on the entrance side and serves to release a  camera  (18). A second measuring value evaluates  all speed  mesuring values occurring in the measuring section (22),  in  which  the vehicle (12) is  detected  by  the radar  beam  (20).   This   second   mesuring  value  is recorded.            (Fig. 1)

Granted: 1992-08-11
Abstract: A B S T R A C T           An electrical flux conducting rotor having an axis of rotation.  The rotor is formed with a stack of sheet metal blanks laminated together with the blanks extending perpendicular to the axis of rotation.  The blanks have similar outline shapes disposed in alignment in the stack.  The outline shape of each blank has a symmetry such that any blank in the stack is capable of being stacked in outline alignment with any other blank when displaced in such stacked relation angularly about the axis of rotation of said rotor a plurality of equal angular divisions of 360°.  Each blank has a predetermined orientation based upon being similarly blanked from the same metal sheet.  The blanks of the stack are arranged preferably in one group which contains four successive blank sections.  Each blank section contains a number of blanks equal to the number of blanks in each blank section.  The blanks of the outer two blank sections are displaced angularly 180° respect to the predetermined orientation relative to the inner two blank sections so as to statically and dynamically balance the orientation of the blanks of the blank sections about the axis of rotation of the rotor. Preferably, an outer two blank section and an adjacent inner blank section are also inverted with respect to the predetermined orientation relative to the other two blank sections.

Title: Method and apparatus for making an asphalt-aggregate pavement
Inventor: BROCK JAMES D
IPC: B60P1/38
Filed: 1989-07-21
Granted: 1994-04-12
Abstract: ABSTRACT OF THE INVENTION          An apparatus and method for delivering asphalt-aggregate material from a plurality of supply trucks to a finishing machine.  In a preferred form of the invention the hopper of the finishing machine is modified to have a capacity substantially equal to the capacity of one of the supply trucks.  The apparatus is a self-propelled storage vehicle including a hopper having a capacity substantially equal to the capacity of one of the supply trucks, a high capacity loading conveyor, and a high capacity unloading conveyor system.  A transversely disposed screw auger is provided for remixing the asphalt-aggregate material in the hopper prior to its discharge to the finishing machine.  In the first method of operation the storage vehicle shuttles between the finishing machine and a remote location of the supply trucks and in the second method of operation the storage vehicle travels in tandem with the finishing machine as the paving operation is performed.  The high capacity loading conveyor can be equipped with an extendable trough which has a pivotally attached trough floor with front and side plates.  The extendable trough provides a large area which facilitates discharge of paving material from frameless trailers and allows for the early departure of the supply trucks from the conveyor.  The final discharged paving material is gradually emptied from the extendable trough into the conveyor by hydraulic cylinders which tilt the trough to slide the material in the trough into the infeed end of the conveyor.
