Title: Cleaner assembly for a roller with a soft mantle surface
Inventor: HES HARALD
IPC: B41F35/06
Filed: 1998-06-16
Abstract: The assembly (10) to clean the surface of a roller (18), with a soft mantle surface (18a), has a blade placed against the soft mantle surface (18a) at an acute angle ( beta ) to it, and against the direction (D) of roller (18) rotation. For the cleaning action, the cleaning assembly (10) is moved out of a rest position and set against the soft mantle surface (18a) of the roller (18).  It is initially placed at an acute angle ( beta ) to the roller surface and then the pitch is increased to a second angle.  The first angle ( beta ) is 0-25 deg  and the second angle is 15-45 deg . While the pitch angle is being increased, the contact position (L) of the cleaner (10) is maintained or shifted by a co-ordinate system (K) fixed to the machine frame.  After contact between the cleaner (10) and the soft roller mantle surface (18a), the linear force is steadily increased by the cleaner on the mantle surface, and it is further altered while the pitch angle is increased. At the end of the cleaning operation, the angle of the cleaner (10) is returned to the lower first pitch angle ( beta ), the linear force of the cleaner on the mantle surface is reduced, and the cleaner is withdrawn to the rest position. The roller mantle surface (18a) is sprayed with a fluid as the cleaner is moved to make contact with it and, if required, when the contact is broken.  A stronger fluid (26) is delivered to the roller mantle surface during the cleaning action, and is removed by suction extraction. The roller mantle surface (18a) is of a material with a hardness of 40-120 P and J. The cleaner (10) has a scraper blade (14), a fluid spray and an air brush system.  It can be fitted with two scraper blades.

Title: Analog to digital convertor
Inventor: CHANG DONG-YOUNG
IPC: H03M1/06
Filed: 1998-07-09
Abstract: Uses a metal-metal capacitor with minimum parasitic capacitance value. A switch (202) selects an output signal from a sample and hold amplifier and then selects a feedback signal. A subtracter (203) provides a difference value between the analog signal output by a switch and that from a digital to analog convertor and this output is amplified. A second sample and hold amplifier (205) samples and holds the amplified output and feeds back a resulting signal to the switch. A digital correction device outputs a digital signal with N bits. A time controller (209) generates a control signal and a timing control signal for the operation of each device.

Patent DE-19842534-A1 (DE)
Inventor: DANTLGRABER JOERG
IPC: B29C45/82
Filed: 1998-09-17
Abstract: The aim of the invention is to create a hydrostatic drive system for the mobile mold closing plate (10) of an injection molding machine in which only small amounts of unusable energy are lost. To this end, the hydraulic pump (19) can deliver a pressure medium in a compressed-medium ductwork system (17, 24) comprising a hydraulic accumulator (24), and the first pressure chamber (15) of the hydraulic cylinder (11) is connected to the compressed-medium ductwork system (17, 24). In addition, the hydraulic cylinder (11) is controlled by a hydraulic transformer (18) which is basically constructed in any manner. Said hydraulic transformer is located with the primary pressure connection (32) thereof on the compressed-medium ductwork system (17, 24). Pressure medium can be fed to the second pressure chamber (16) of the hydraulic cylinder (11) or can be carried away from the second pressure chamber (16) via the secondary pressure connection (34) of the hydraulic transformer. According to the inventive hydrostatic drive system, the rapid, high demand for pressure medium from the hydraulic accumulator (24) when the mold closing plate (10) closes during the acceleration phase can, to a large extent, be covered. When braking the mold closing plate (10), the hydraulic transformer (18) can assist in refilling the hydraulic accumulator (24). The hydraulic accumulator (24) can be filled again by the hydraulic pump (19) during idle times in which the mold closing plate (10) is in an non-operating state.

Title: Catalytic converter for internal combustion engine
Inventor: YAMASHITA YUKIHIRO
IPC: F01N3/08
Filed: 1998-10-07
Abstract: A catalytic converter (19) in the exhaust of a lean burn internal combustion engine (1) absorbs nitrous oxides. It is kept at the optimum temperature by controlling the fuel/air ratio of the mixture fed into the engine. The lean mix is set at a level lower than the stoichiometric value, which cools the converter. A second, richer level, which causes the converter to desorb nitrous oxides and which increases the temperature of the converter, is set in the controller and the controller cycles between the lean and rich settings. The switching ratio is varied to keep the temperature of the converter at the optimum level. No additional controls are required for supplying air or fuel into the system.
