Abstract: The present invention is an ink jet printer utilized to enlarge color images. Signals from a scanned image are converted by a color correction computer into control signals representing the density of the individual pixels of that scanned image. The color density signals are used to control the application of ink from ink jet spray nozzles located on a pair of printheads. Thus, the ink jet printer of the present invention reproduces the image on both sides of a translucent substrate to enhance the quality of the viewed image. The present invention is further provided with dual air sources to apply the ink. A first source is pulse width modulated to control the amount of ink sprayed onto the substrate. A second air pressure source is continuously applied to the ink jet spray nozzles to remove the excess ink that accumulates about the nozzles during print operations.

Abstract: A single pass color xerographic printing system with a single polygon, single optical system Raster Output Scanning (ROS) system has a multiple wavelength laser diode source for the ROS which images the multiple beams at a single station as closely spaced spots on a multiple layer photoreceptor with each photoreceptor layer sensitive to or accessible to only one of the multiple wavelengths.

Abstract: A balance with a weighing system protected against overloading includes a load receiving member and a weighing dish placed on the load receiving member. The weighing dish rests on dampening elements which are mounted at ends of two U-shaped levers which are supported in a central yoke. The yoke includes abutments which hold the two levers in a horizontal position in an articulated manner. When a load which is within the weighing range is applied to the weighing dish, the two levers and the yoke form a rigid unit. If an excess load is placed on the weighing dish, either dynamically or statically, the two levers are pivoted and tension a stack of springs mounted in the abutments. In addition to dampening by the pivoting of the two levers and tensioning of the stack of springs, additional dampening is effected by dampening elements between the lever ends and the weighing dish.

Abstract: The method and apparatus for verifying that the correct postage has been paid includes a mail processing machine which is adapted to receive properly oriented mail via a transport from a facet apparatus. The mail processing machine includes a scale for weighing a mailpiece having postage affixed thereto for the purpose of cancelling it with a mark which includes the actual postage which should be affixed. In a further embodiment other information necessary to calculate the necessary postage is obtained by reading the information from the mailpiece. Any discrepancies between the postage affixed and the amount of postage which should actually be paid may be noted at acceptance or seen by the carrier as the mail is delivered. A batch of mail may be sampled to select representative mailpieces in a random manner and verified to compare the calculated total of postage required based on the sample to the postal amount paid for the batch by the sender.

Abstract: A mobile weighing system for use on a truck or trailer to weigh a load carried by the truck or trailer. A load support frame supports a load and is positioned over the frame of the truck or trailer. A plurality of weighing cells are mounted over the truck or trailer frame in such a manner as to bear an approximately even distribution of the load. Each weighing cell comprises a lifting mechanism having an extended position and a rest position, a vertically disposed tension load cell and a linkage assembly coupling the lifting mechanism and the load cell to cause an upward force on a top end of the load cell when the lifting mechanism is extended. The bottom end of the load cell is attached to the support frame so that the support frame is suspended by the load cells when the lifting mechanisms are extended. The lifting mechanisms and linkage assemblies of the weighing cells are attached to the truck or trailer frame.

Abstract: Load shift compensation of a strain gage load cell is accomplished by connecting a pair of fixed resistors in series across the output of a bridge circuit incorporating the load cell strain gages. The junction point between the series resistors is established at a desired signal level by a digital to analog converter connected thereto or by a voltage divider network so that, in effect, a part of the resistance of the resistors required to achieve load shift compensation is made to shunt a pair of the strain gages in the bridge circuit. The required signal level may be established by positioning weights on the scale platter at different positions parallel to the longitudinal axis of the load cell beam and adjusting the signal level at the junction point between the shunting resistors until a desired degree of compensation is achieved. The digital correction value required at the input of the digital to analog converter to achieve compensation is stored in the memory of the scale computer.

In this procedure a load support having supporters (23), e.g. a vehicle or container, is provided with transducers (1a, 1b, 2) whose output signals are used to determine the weight of the load (K). According to the invention, the transducers are mounted on the rigid frame (4) of the load support near the fixing points (6; 6a, 6b, 6c, 6d) of the supporters (23; 27) and used to measure the deformations and/or stresses caused by the load, the weight of the load being determined on the basis of these.

Abstract: A four color toner single pass color printing system consists generally of a raster output scanner (ROS) optical system and a quad-level xerographic unit which will deposit blue, yellow or black toner and a tri-level xerographic unit which will deposit magenta or cyan toner. The yellow toner is transmissive to the red or infrared light from the raster output scanner (ROS) optical system to allow ease of exposure of the underlying photoreceptor. The resulting color printing system would be able to produce pixels of black and white and all six primary colors.

Abstract: A core conveyor system for electric motor manufacturing apparatus, including a core weighing station for improving the accuracy of stock measurement in manufacturing electric motor stator and rotor laminated stacks or cores from sheet stock. Stock is initially measured to determine a measured stack thickness. The weight of the manufactured stack is used to calculate the thickness of the stock material used. The calculated thickness is used to recalibrate the measured stock thickness. The weight of the stack, if not between a selected maximum and minimum values, determines if the height of the manufactured stack is acceptable. The core conveyor also includes secondary stations for other core manufacturing operations.

Abstract: A weight measuring device includes two piezoelectric elements. The first piezoelectric element induces vibration in an object to be measured, and the second one detects the reaction force of the object generated by the vibration. This force is detected by a voltage monitor circuit as an output voltage from the second piezoelectric element. From the voltage which has been detected, the weight of object is determined. The device further includes an absorbing element to absorb unnecessary piezoelectric strain in reaction force generated when the object vibrates. The invention provides a compact weight sensor which can be produced at low cost, and which can measure weight with high accuracy.
