Abstract: A snowplow leveling system is described for use on a standard plow mounting structure having a reversing table mounted to a plow blade system and rotatably mounted on a support frame. The support frame is pivotally mounted about a horizontal axis onto a motor vehicle which has an elevatable lifting point. The snowplow leveling device is mounted on the support bar of the reversing table. The leveling device may include two slider mechanisms mounted on support tracks located on opposite ends of the support frame of the reversing table. Positioning struts hingedly connect the slider mechanisms to the support frame. Additionally, a lifting chain connected at each end to the slidable mechanisms and in the middle to a lifting hitch attached to the support frame aids in maintaining the leveling position of the snowplow system of the present invention.

Title: Load measuring system for refuse trucks
Inventor: BOWMAN ALLAN
IPC: G01G19/08
Filed: 1990-12-21
Granted: 1999-09-07
Abstract: A load weighing system for refuse trucks preferably of the type using a front end loader which lifts, empties and lowers containers. Measurements are made of variable angles of pivoting elements and forces within hydraulic cylinders causing the pivoting elements to pivot. Other measurements are made of geometric constants in the apparatus. Sensors monitor the measured variables and the output is provided to a computational unit. The computational unit has been pre-programmed with the measured geometric constants and combines the variables with the constants to calculate a distance to the center of gravity of a container being emptied. Once the distance is calculated, the measured force within the hydraulic cylinder can be used to calculate a weight. The weight of the container being lowered as calculated is then subtracted from the weight of the container raised as calculated. The resultant weight is the weight of the refuse emptied from the container.

Title: Oil burner and method
Inventor: O'BRIEN DENNIS J
IPC: F23D11/00
Filed: 1991-05-27
Granted: 1999-01-12
Abstract: A gun-type oil burner is disclosed having a motor axially aligned with a fuel pump and a blower at opposite ends.  The blower draws air into the burner, the amount of which is controlled by an adjustable air gate.  The blower inlet is covered by a removable, protective air scoop.  Upon removal of the air scoop, an outside air boot is easily connected to the burner without burner modification.  The air in the burner travels along a serpentine path which contains smooth curves and perimetrally disposed protrusions for reducing the velocity of the air flow and maintaining its static pressure.  The air flows through an air tube in a helical pattern, mixes with oil and is ignited at the air tube outlet. A fuel nozzle, ignitors and a fuel supply conduit are supported as a burner sub-assembly within the tube by a spider.  A preselected stop of a number of removable stops of differing sizes is located on the spider and properly positions the burner sub-assembly within the air tube.  The burner sub-assembly may be viewed through a window located near the rear of the air tube on the burner assembly.

Title: Dispenser of plastic bags with handles
Inventor: CARPENTER LEN
IPC: B65D33/00
Filed: 1991-09-30
Granted: 1995-09-26
Abstract: A roll of plastic bags sequentially disposed in end-to-end relationship, each bag having two spaced handles, separated by a gap, and extending upwardly along the edges at the top end of each bag,  each bag being joined to a following bag by a perforated line, is disposed in a box-like dispenser having a front face.  A dispensing opening in the front face has a first cut-out portion and a second, spaced cut-out portion with a tab extending upwardly between the cut-out portions.   The tops of the cut-out portions, when joined together, define a bottom boundary overlying the cut-out portions and the tab.   The top of the tab and the bottom  boundary  are   separated  by  a  gap  which  is substantially wider than the thickness of the plastic bags.          Thus, when a bag is withdrawn, the handles of the next bag will fall into a respective one of the cut-out portions and lie outside of the dispenser so that the next bag is easily accessible for later dispensing.

Inventor: HOLMBERG SCOTT H
IPC: G02F1/1343
Filed: 1991-11-05
Granted: 2001-07-10
Abstract: Flat panel displays are provided with overlying interconnected and hence redundant bus lines to reduce fatal defects. The redundant, generally row lines are interconnected at least at two locations on a line and can be connected at each pixel to further reduce defects. The redundant row or gate line is formed by an overlying light shield line which preferably is of low resistivity and enhances the operation of the displays. The display can include subdivided subpixels and one defective subpixel is generally an acceptable non-fatal display defeat, since the rest of the subpixels are still operative. The subpixels can be formed with common or redundant column bus lines.

Inventor: DURTLER WILLEM G
IPC: H03G3/20
Filed: 1993-02-04
Granted: 2004-02-03
Abstract: An automatic level control circuit for cellular telephone transmitters which is compatible with both existing analog cellular service and. expected next generation digital TDMA service. The circuit automatically and dynamically changes modes to maintain communication when a mobile subscriber moves from one type of service to another. In a first mode of operation, which is compatible with existing analog cellular service, the circuit provides a closed loop negative feedback circuit which produces a control signal for continuously controlling the output power level of the transmitter amplifier. In a second mode of operation, which is compatible with proposed digital TDMA service, the circuit operates to alternately close the negative feedback loop during the periods when the transmitter is permitted to transmit (assigned TDMA frames) and open the loop during other periods when the transmitter is turned off. When the loop is opened, the invention temporarily stores the magnitude of the control signal. This stored value is subsequently used to quickly restore the amplifier to its assigned power level during successive frames when the loop is again closed for burst transmission.
