Title: Valve control unit for a hydraulic elevator
Inventor: DEL RE LUIGI
IPC: B66B11/04
Filed: 2001-06-01
Abstract: The invention relates to a valve control device (28) for a hydraulic elevato r. Said valve control device comprises two control valves (5, 15) which are use d to control the flow of hydraulic oil from a lifting cylinder driving the elevator car or from the lifting cylinder to the tank. During the upward journey of the elevator car, hydraulic oil is fed from the tank to the lifti ng cylinder via the valve control unit (28) by means of a pump which is driven by an electric motor. During the downward journey of the elevator car, the hydraulic oil flows to the tank via the valve control unit (28) without the pump being in operation. According to the invention, a respectively individu al control valve (5, 15) is provided in the valve control unit in order to control the upward and downward journeys of the elevator car, whereby each valve functions as a return valve and a proportional valve. Each control val ve (5, 15) is provided with a throttle element (35; 55) which can move in relation to the seat (36; 56). A readjusting spring (37; 57) and a relay val ve (5v; 15v) act upon the throttle element (35; 55) and can be actuated by an electrically controllable proportional magnet (5M; 15M). The valve control unit (28) is easily constructable and can therefore be produced at low cost.  One particular advantage of the invention is that adjusting elements are not  required.

Abstract: A method and apparatus for processing mail is provided. The mail is serially fed from a stack of mail into a system transport. The system transport conveys the mail to a reader, which scans the mail to obtain image data corresponding to at least a portion of each piece. From the imaging station, the mail is conveyed to a scale, which weighs each piece. After the address for a piece of mail is determined, the piece is conveyed to a labeler, which applies a postage label onto the piece. In the preferred method of operation, the postage printed on the label is determined based on the determined address and the determined weight of the piece. After the postage label is adhered to the piece, it is conveyed past a verifier, which scans the printed label to ensure that the postage was printed properly, and the label was properly adhered. The mail is then sorted and stacked in a plurality of output bins.

Title: Short inking unit for a rotary printing machine and method of improving the ink splitting in such a short inking unit
Inventor: SCHNEIDER JOSEF
IPC: B41F31/02
Filed: 2002-05-22
Abstract: linking unit rolls include at least one ink applicator roll, which rotates in an ink fountain filled with printing ink and picks up printing ink from the latter, and a plate cylinder, which serves as a printing plate carrier and onto which ink can be transferred, directly or indirectly, by the ink applicator roll. The short inking unit is therefore equipped with a small number of inking unit rolls and, at the same time, nevertheless ensures a uniform, homogeneous application of ink to the plate cylinder, that is to say the ink splitting on ink-carrying rolls of a short inking unit for a rotary printing machine is improved. At least one of the inking unit rolls is provided, at least on its surface, with a coating having powerful microdipoles, in particular made of ferroelectric material. This circumferential surface is assigned electric means in order to produce an electric field by means of a DC/AC  voltage, in order to polarize and depolarize the microdipoles of the circumferential surface in the form of a homogeneous or periodic charge image, so that an ink layer resting on it is given a desired electric roughness.

Patent CA-2397728-A1 (CA)
Inventor: HATTA SHIN-ICHIRO
IPC: H01J29/06
Filed: 2000-12-19
Abstract: The distribution of geomagnetism on the earth is complicated. Even if an internal magnetic shield and a mask are installed on a flat screen color CRT, it is difficult to make an effective compensation for the displacement of the point that the electron beam reaches on the fluorescent screen due to the external magnetism such as the geomagnetism, depending on the place where the CRT is installed on the earth. As a solution for this problem, a stripe color cathode-ray tube having a big tolerance for vertical difference in the point that the electron beam reaches is used. A gap of nonmagnetic or hard magnetic material or an air gap is provided between the mask frame and the internal magnetic shield so as to allow the magnetic flux flowing into the inside of the mask from the frame (from the edge of the mask of some type) of the internal magnetic shield to flow outside the mask.
