Title: Methods and apparatus for making an asphalt-aggregate pavement
Inventor: BROCK JAMES D
IPC: E01C19/48
Filed: 1988-08-24
Granted: 1992-06-23
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.

Title: Flow sensors
Inventor: YOUNG DONALD C
IPC: G01F1/28
Filed: 1988-10-07
Granted: 1993-05-25
Abstract: ABSTRACT     IMPROVEMENTS IN OR RELATING TO FLOW SENSORS    A flow sensing device inckudes a micro-engineered cantilevered beam (1) on a semiconductor substrate (2) and is sensitive to a characteristic of the beam which is indicative of fluid flow.  Fluid may cause displacement of the beam which depends on fluid velocity.  Displacement may be determined, for example, by sensing capacitance between beam and contacts (4,5), by optical methods or using a strain gauge or stress sensor.  A change in resonant frequency or a change in dsiplacememt of a heated beam due to fluid may be measured.  End contacts may be fabricated.  Circuitry can be incorporated on the same chip as the  beam.

Title: Arc welder with improved arc striking capability

Granted: 1993-03-09
Abstract: ARC WELDER WITH IMPROVED ARC     STRIKING CAPABILITY                         Abstract A pulse type arc welder with improved arc starting characteristics. An output voltage level sensor (2017) monitors the output voltage to determine whether the arc has been struck. If the arc has not been struck, a first oscillator (2000) gates a second, higher frequency oscillator (2002) so that the input to the driver (2010) is a chopped, pulsed, high duty cycle waveform.  Also, the bandwidth of the output current level sensor (2012) is reduced so that the high value, short lived arc starting transient current does not cause the output current level sensor (2012) to improperly shut down the driver (2010). Additional current limiting protection is provided during this period since the high chopping frequency causes the reactor (2010a) to have a high impedance. After the arc has been struck, the output voltage will drop to the arc sustaining voltage and the output voltage level sensor (2017) will de-energize relay (2003). The first oscillator (2000) then provides the driver (2010) with an input signal having the characteristics selected for the particular welding operation. Also, the bandwidth of the output current level sensor (2012) is restored to its full value.

Abstract: ABSTRACT                  PNEUMATIC DOOR OPERATOR HAVING NOVEL PNEUMATIC ACTUATOR AND LOCK     A power door operator for transit vehicles utilizing a rodless pneumatic cylinder (10) to open and close doors (2,3)  in the  sidewall of a vehicle.   Door movement having a controlled door edge force is achieved through coupling an external piston  (11) of the cylinder and vehicle doors  through belt  (16).   Magnetic coupling between internal and external pistons of the cylinder provide force having breakaway value applied to the operated door.  A novel lock (30, 31, 32, 33) operated by admission of air to the cylinder (10)  latches or unlatches the door in its closed position subsequent or prior to door  closing or opening.   Control of door motion at the ends of its travel is achieved through the use of a novel differential area (10a) in the cylinder.          Piston  force  is  modified  for  positions  approaching either end of the cylinder using a sliding rod (40) contained by the piston (10a).  Movement of the rod modifies available force.

Abstract: Abstract A  shield  stripping  apparatus  for  stripping  an  outer shield from an electrical cable.   The apparatus includes a housing with a shaft rotatably mounted therein.   A cable guide head is removably attached to the shaft and includes a wire receiving and guiding aperture therethrough.  The guide head further defines a transverse blade receiving groove or slot adjacent the aperture.   A cutting blade is pivotally mounted in the slot and may be pivoted through an angle of approximately 90° between a retracted position and a cutting position.   In the cutting position, a cutting edge on the blade extends into the aperture for engaging and cutting the outer shielding of the cable.  During the cutting operation, the cable is pulled through the guide head.  Because the guide head and shaft are free to rotate, the blade will be guided along spirally wound wires within the shield such that the guide head and shaft rotate as the cable is pulled therethrough.   In the cutting position, a free end of the blade engages a shoulder on the guide head which prevents over-rotation  of  the  blade  and holds  the  blade  in  the cutting position as the cable is pulled through the aper-ture.

Abstract: Apparatus for cleaning pipelines of finite length has a four-way flow reversing valve whose body admits a liquid cleaning agent from an inlet into one port and thence into a pipeline whence the cleaning agent flows back into the body by way of a second port and is discharged by way of an outlet. The valving element is a piston which is reciprocable between two end positions in one of which the flow of cleaning agent takes place as outlined above and in the other of which the cleaning agent flows first into the other port and returns into the body of the valve by way of the one port to be discharged by way of the outlet. The body of the valve is separably connected with the larger-diameter end portions of two cylindrical housings whose smaller-diameter end portions are separably connectable with the respective ends of the pipeline. A supply of cleaning elements, such as balls of sponge rubber, is used in the apparatus to automatically change the position of the piston as soon as they impinge upon the one or the other end of the piston.
