摘要： This invention relates to a postage meter having a plurality of worm gears for adjusting the rotational position of postage print wheels. Each worm gear selectively moves a rack which is an engagement with a postage print wheel so as to provide rotational movement to the print wheel. Sensors are provided so that the rotational position of each worm gear can be determined thereby indicating the position of the print wheels.

摘要： An impulse ink jet print head and method of fabricating same. The print head comprises a plurality of superposed, contiguous plates including a nozzle plate with at least a pair of nozzles for ejecting ink droplets in a direction perpendicular to a plane of the plates. Another plate is a channel plate defining at least a pair of coplanar axially aligned elongated chambers, each connected to an ink supply and having an outlet communicating with an associated nozzle. A diaphragm plate overlies the channel plate and has transducers thereon for displacing ink in each of the chambers to eject discrete ink droplets from the nozzles. Other plates may include a manifold plate for directing ink to a plurality of pairs of chambers and a restrictor plate with restictor orifices positioned between the manifold plate and each of the chambers. The method of fabricating the print head includes forming the different plates, forming the transducers, and assembling all of the components in a particular relationship.

摘要： A weighing device is disclosed which comprises a frame, a pan element for supporting a load to be weighed, a channel member connected to the pan for retaining a plurality of weight elements in a vertically movable manner, a motor supported within the frame and a shaft member operatively connected to and extending from the motor, the shaft member including a spring for supporting the pan element. A plurality of collapsible support members are secured at one end thereof to the frame and each have at their opposite ends a device that is adapted to receive and lift one of the weight elements when the support member is in an extended and non-collapsed position. A camming arm is secured to the shaft member and extends in a direction toward the support members. A switch is provided for energizing the motor when the pan is depressed by a load. The motor turns the shaft member and guides the camming arm into contact with successive collapsed support members in a step-by-step manner to place a number of the support members in an extended position and lift a corresponding number of the weights substantially equal to the weight of the load.

摘要： A steerable wing-type sail system for a wind powered craft. The system includes first and second secondary airfoils and that are spaced outwardly to the sides of the plane of the main sail, and that are positioned rearwardly of the trailing edge of the sail. The secondary airfoils are selectively pivotable so as to steer the main sail in one direction or the other. The main sail is also provided with a pivoting flap at its trailing edge, which pivots simultaneously with and in the same direction as the secondary airfoils. The secondary airfoils are carried on elongate horizontal booms mounted near the mid-span height of the main sail. The secondary airfoils pivot about vertical axes at the distal ends of the booms, and are operated by control cables that are retracted and paid out by linear actuators or similar mechanisms. The craft may be multi-hull vessel, such as a catamaran. The control mechanism for the secondary airfoils may operate the airfoils in response to signals received from one or more onboard sensors. The system is suitable for use on an autonomous unmanned surface vessel (AUSV).

摘要： An apparatus and method for deskewing sheets as they are transported along a path. An intake roller assembly and an urged roller assembly are positioned along the path. The urge roller assembly bears upon a sheet with a forced selected so that the urge roller will slip if the sheet is blocked before the sheet is damaged. A rotatable element having a pair of stop elements in an upstream and a pair of deflecting elements at a downstream end is pivotable mounted beneath the path and rotates in a plane normal to the path, and is bias so that the deflecting elements intersect the path and the stop element are clear from the path. When the intake roller assembly drives a sheet against the deflecting elements the rotatable element rotates as the sheet rides over the deflecting element so that the stop elements intersect the path. If the sheet is skewed, that is if one edge is advanced, that edge will encounter the stop elements first. The urge roller assembly will then slip on the advanced side of the sheet while driving the other side forward until the sheet is deskewed. As the sheet is deskewed the deflecting elements are cleared and the rotatable element rotates to remove the stop elements from the path and the deskewed sheet continues for further processing. A pair of parallel guide plates are provided above and below the path to guide the sheet and increase its effective stiffness.

摘要： A thermal printing postage dispensing apparatus that is able to print a postage indicia on a mail piece in a secure manner. A thermal ribbon is provided which has pre-formed images thereon that are of a reduced size in the longitudinal direction. When the images are to be transferred to an envelope to print a postage indicia by a dot matrix thermal printer, the envelope is driven at a greater speed than the ribbon. This results in the indicia being printed on the envelope with a standard size. The preformed images represent the non-variable portion of a postage indicia; whereas, the variable data of the postage indicia is printed by a thermal printer in blank areas left by the pre-formed images.

摘要： Oscillating and alternatively locking apparatus and method of determining the mass of an article by the shift of the period of oscillation of a flexibly mounted platform. An article whose mass is to be determined is placed upon the platform. The platform is caused to oscillate and the period of harmonic motion is calibrated. This period is compared against the period of harmonic motion when there is no article upon the platform, and the difference, or shift, in frequency, allows a determination of the mass of the article. A reversible motor is used to provide drive to a conveyor for transporting mail pieces onto the tray and for causing oscillation of the tray for purposes of weighing.

摘要： The ink ejecting portion of an ink jet printer is described, wherein a single ceramic transducer is used to create the pressure for the ink droplets. Unlike prior devices, the transducer is a one-piece member as opposed to use of a crystal and diaphragm. The one-piece member is practical because of the generally spherical configuration of the crystal.

摘要： An ink jet printing head comprising an array of successive pairs of cavity plates and transducer plates. The transducer plates are one-piece elements composed of piezo-ceramic material and can have multiple diaphragms on opposing faces matching with cavities in the cavity plates. Many such pairs of cavity plates and transducer plates can be joined together to form a printing head which can achieve a very high density of nozzles, specifically, on the order of 150 to 200 nozzles per inch.
