Inventor: FUHRMANN HARTMUT
IPC: B41C1/10
Filed: 1989-10-10
Abstract: To provide an electrically controllable printing form, on which the printing image is retained even upon repeated application of printing toner or printing ink formed of toner suspended in a carrier liquid, the printing form (10) has a surface layer (12) of ferroelectric material or, if a gravure form (40), the cells (31) have a bottom (32) of ferroelectric material.  The form is programmed under control of a control unit (13, 13') by an electrode (14, 14') which selectively polarizes the ferroelectric material.   Upon application of electrically charged toner or ink, the ink or toner particles which are charged oppositely to the polarization of the ferroelectric layer or bottom will be retained, the equally charged particles repelled, so that, by selective positive or negative polarization, two-color printing can be effected at one pass of a printing substrate over the form.

Title: Two-stage coal gasification process
Inventor: HENLEY JOHN P
IPC: C10J3/46
Filed: 1989-10-11
Abstract: ABSTRACT     A two-stage upflow process for coal gasification and an apparatus useful therefor.  An oxygen-containing gas and a first increment of a coal-in-water slurry are ignited in a horizontal fired slagging reactor by means of horizontal coaxial juxtaposed burner nozzles mounted in the reactor, thereby converting the oxygen, the coal, and the water into steam and gaseous combustion products.  The discharge from the fired reactor is contacted overhead with a second increment of coal-water slurry in a vertical unfired heat-recovery unit connected to the upper end of the reactor.  The heat evolved in the reactor is used in the heat recovery unit to convert the second increment of coal-water slurry into more steam, char and synthesis gas.  The gas effluent is separated from the solid char, and synthesis gas is passed into a fire-tube boiler to recover heat and the cooled product gas is recovered as the desired fuel-rich product.  The 29,860A-F     solid char is reslurried and recycled to the fired reactor 3 for further combustion.     29,860A-F

Filed: 1990-04-12
Abstract: APPARATUS FOR REMOVING A SOFT STOPPER FROM A      CONTAINER         ABSTRACT     An apparatus for removing a soft stopper such as a cork from a container such as a bottle. The apparatus includes a hollow cylinder having one or more slits along its length and a handle attached to the top of the cylinder. The interior surface of the cylinder includes one or more spiral wound threads having a flat upper surface. The cylinder is inserted between the outer circumference of the cork and the interior wall of the bottle and is rotated so that the threads are embedded in the outer wall of the cork and serve to compress the cork inwardly as the apparatus  is screwed into the container. A stop ring serves to limit the penetration of the apparatus into the bottle and when the apparatus has reached its maximum penetration, the apparatus begins to force the cork out of the bottle as the turning motion of the cork continues.  Various  embellishments  serve  to  enhance  the efficiency of operation of the device.

Title: Tray of discharged paper for recording apparatus
Inventor: GOTO KAZUO
IPC: B65H31/02
Filed: 1990-07-24
Abstract: ABSTRACT The tray for discharged paper is utilized in a recording apparatus for carrying out repeat-printing while reciprocating a paper being printed.  A pair of guide bars are provided to support and guide the edges of a paper sheet along its back surface so as to prevent the paper sheet being repeat-printed from coming into face-to-face contact with an upper receiving face of the tray or with a top surface of another printed paper sheet which has already been printed and stacked on the upper receiving face of the tray, thereby avoiding adhesion of the paper being printed to the stacked paper sheet due to static electricity.  This construction can effectively suppress concurrent rolling of the already printed paper sheet to a discharge roller when returning a paper sheet being repeat-printed, and suppress generation of paper jams.

Title: Quench assembly design
Inventor: KOROS ROBERT M
IPC: B01J8/04
Filed: 1990-07-26
Abstract: According to this invention, a quench assembly having improved mixing efficiency comprises a series of mixing zones: quench fluid inlet zane: quench box mixing zone; a jet stirred mixing zone: and a distributor zone. In the quench fluid inlet zone, quench fluid is introduced to fluid from the catalytic bed above. The quench fluid is introduced through holes in a quench pipe, creating a jets of quench fluid which entrain and mix the reactant fluid, typically partially reacted, from the bed above. This mixing zone is separated from the quench mixing zone by means of a horizontally disposed plate having a central opening therein. The reaction fluid and quench fluid enter the quench mixing zone through the central opening in the plate separating the two zones and impinge on a bottom bench mixing zone plate, where the gases are turned radially outward and passed over and around a series of mixing baffles. A plurality of pipes is located in an annular ring near the periphery of the bottom plate of the quench mixing zone for introduction of the quench gas and process fluid into a jet stirred mixing zone. Thus, the flow of fluids coming out of the quench mixing zone is introduced in a swirling direction into the jet stirred annular mixing zone, where the fluids arc further mixed by mutual entrainment. Next, the fluid is turned downwardly through a central opening in a plate separating the jet stirred one from the distributor zone. The distributor zone is provided with a distributor tray for distributing the fluid to the catalyst bed below.
