IPC: C01C1/04
Filed: 1989-02-03
Abstract: PCT No. PCT/NO90/00028 Sec. 371 Date Jun. 27, 1991 Sec. 102(e) Date Jun. 27, 1991 PCT Filed Feb. 2, 1990 PCT Pub. No. WO90/08736 PCT Pub. Date Sep. 9, 1990.The present invention relates to a method of catalytic production of ammonia, where a gas mixture consisting mainly of unconverted synthesis gas, some ammonia, inert gases and possibly also water is recirculated to the synthesis reactor being first freed from the main part of the ammonia and possibly also water by absorption. The gas mixture is brought in contact with a hygroscopic abosrption agent having two or more OH-groups for absorption of ammonia and possibly also water. The absorption is carried out at a pressure being substantially the same as the ammonia synthesis pressure, and ammonia being desorbed from the absorption agent at a lower pressure and higher temperature than at the absorption. At least part of the possibly present water is removed from the absorption agent before it is supplied to the absorption column. Preferably it si applied ethylene glycol, diethylene glycol or triethylene glycol alone or in mixture as absorption agent. Possible water can be removed form the absorption agent by inert stripping gas before it is returned to the absorption column.

Title: Vending apparatus with intelligent dispensation control
Inventor: ODEN KENNETH W
IPC: G07F5/18
Filed: 1990-08-17
Granted: 1999-04-06
Abstract: A vending apparatus ensures that the delay between a customer's selection of an article, and the dispensation of the selected article, is minimized, preferably to less than a predetermined delay, regardless of the point in a multi-article vending cycle.  The reduced selection-dispensation delay is achieved through use of a "memory and learning" feature.  The "memory and learning" feature is predicated on a recall and/or analysis of the relative times of occurrence of one or more previous dispensations, so that the  apparatus'  present  position  in  the  multi-article vending cycle is determined.   The "memory and learning" feature allows the vending apparatus to anticipate how long the article dispensation mechanism should run after the present dispensation, to strategically poise the mechanism for a subsequent dispensation having an optimum selection-dispensation delay.  Also disclosed are systems and methods for ensuring that  articles  are dispensed at a proper temperature,   even  after  a  "sold-out"  condition  is corrected; and for sounding an alarm if a person jars the vending apparatus  in an attempt to  improperly jar an article from the vending apparatus.

Patent CA-2036314-C (CA)
Title: Linearized three state phase detector
Inventor: GILLIG STEVEN F
IPC: H03D13/00
Filed: 1991-02-14
Granted: 1997-03-18
Abstract: A linearized three state phase detector (300) that exhibits a linear transfer function of phase to current or charge at and around the zero phase error region. The inputs to the D flip-flops (301 and 302) are tied to a logic high. The first flip-flop (301) is clocked with reference signal Fr while the other flip-flop (302) is clocked with a variable frequency feedback signal Fv. Fv is typically from a voltage controlled oscillator in a phase locked loop. The outputs of the flip-flops are ANDed together with the result of this operation going through a delay element (304) before reseting one of the flip-flops (301). The other flip-flop (302) is reset by the output of the AND gate (304) without the delay element (304). Each flip-flop output enables a charge pump - one negative polarity (306) and one positive polarity (305). The present invention (300) will maintain a lock condition in a phase locked loop by extending the DOWN pulse enabling the negative polarity charge pump (306) to the same width as the UP pulse that enables the positive pump (306). This will create a net zero charge from the present invention (300).

Abstract: LIQUID-CRYSTAL DISPLAY UNIT FOR ELECTRONIC DIRECTORY            ABSTRACT OF THE DISCLOSURE      A liquid-crystal display, preferably eighteen lines of forty characters each, is mounted in a case.  The temperature of the display medium is held within operating limits for the display -- notwithstanding ambient temperature and humidity variations over generally normal ranges for at least the tem-perate zones, and even if the display unit receives direct sunlight.  The unit works outdoors, at temperatures to at least 46 °C (115 °F) as well as in buildings with no temperature control.  This is accomplished by use of a shading hood, and a window (preferably unperforated polycarbonate, curved, upward-and-outward-concave, and cylindrical-segment) that reflects to a viewer only light from the hood underside.  No ventilating fan, plenum or other ventilating opening is needed.  A circuit-board-mounted temperature sensor controls the contrast-adjust-ing voltage of the display -- using data in a digital-memory "look up" table.  A heater is preferably provided, also temper-ature-controlled.  The entire unit can be flush-mounted in a wall without disrupting operation.  Visible glare arising in reflection at the window is reduced by the hood-and-window combination, without need for any antireflection coating on the window.

Granted: 2005-04-05
Abstract: A package for sliced food product comprising a bottom wall, a top wall, opposite sidewalls and opposite end walls, wherein the package includes a flap which comprises portions of the top wall and/or an adjoining sidewall of the package, and which is movable between a closed position and an open position to selectively facilitate access to the package interior. The package is preferably made of a thin, flexible plastic material.      The flap is removably retained in closed position by a peelable seal extending along one or more edges of the flap, or at least along portions thereof. The package is configured so that when the flap is in open position, the sliced food product is accessible from the side, which facilitates engagement of slice edges and subsequent separation thereof, as well as removal of the slices without undue distortion. This makes the package particularly useful in conjunction with packaging of certain sliced cheeses, although the package may also be useful with other products as well.
