Abstract: An image forming device (2) has a first connector (3) and a second connector (4) for connecting an internally disposed printer engine (1) to a first external device (5) and a second external device (6), and a control unit (7) having ar. alternate operation mode in which communication with the first external device (5) and second external device (6) is performed alternatingly by changing over communication at a predetermined cycle. During communication with either one of the first and second external devices (5, 6), the control unit (7) enables reception of commands and/or a print-start signal from this external device and refuses reception of commands and a print-start signal from the other external device. When communication is changed over from one external device to the other external device, the control unit provides an interval in which reception of commands and a print- start signal from both external devices is refused for a predetermined period of time.

Title: Interlock mechanism for lateral file cabinets
Inventor: HOFFMAN KEITH A
IPC: E05B65/466
Filed: 2002-12-13
Granted: 2008-12-02
Abstract: The invention relates to interlocks for file cabinets and the like which generally prevent more than one drawer from being opened at a given time. The interlocks include a elongated, flexible member which is changeable from a high slack condition to a low slack condition. In the low slack condition, the interlocks prevent their associated drawers that are closed from being opened. In the high slack condition, the interlocks allow their associated drawer to be opened. The interlocks may be used in conjunction with a lock that selectively changes the cable from a high slack condition to a low slack condition and vice versa. The interlocks may be constructed to exert a force on the cable that is independent of the pulling force exerted on a locked drawer. Alternatively, the interlocks may be constructed to exert a force on the elongated, flexible member that is a small fraction of the pulling force exerted on a locked drawer.

Abstract: A door latch operator mount comprises a coupling member and a bearing member. The coupling member includes a plurality radial flanges and an integral resilient arcuate tab member projecting angularly outwardly of the outer surface of the coupling member. The coupling member is mounted to a door for receiving the bearing member. The bearing member has an opening for rotatably receiving a shaft of the latch operator. The bearing member also includes a plurality of flanges and an arcuate channel which tapers in depth. When the bearing member is positioned against the coupling member, the distance of the bearing member flanges from the surface of the coupling member is less than the distance of the coupling member flanges form the surface. The tab member is received in the deeper portion of the arcuate channel. Upon relative rotation, a shoulder on the tab member seats in a notch in the shallower portion of the channel and the bearing member flanges are positioned between the surface of the coupling member and the coupling member flanges. The tab member is urged inward creating a force biasing the bearing member outwardly away from the coupling member and forcing the respective flanges against one another. The bearing member is thus secured to the coupling member and the latch operator is mounted to the door for operative connection to a latch retraction mechanism. A tool is provided for releasably engaging the bearing member enabling rotation of the bearing member relative to the coupling member.

Title: Treatment of a gas stream containing hydrogen sulphide
Inventor: GRAVILLE STEPHEN RHYS
IPC: B01D53/86
Filed: 2001-09-04
Granted: 2009-11-24
Abstract: Oxygen or oxygen-enriched air is employed to support combustion in furnace (16) of part of the hydrogen sulphide content of a first feed gas stream.  Sulphur is extracted from the resulting gas stream in a sulphur condenser (26). Catalyst Claus reaction between hydrogen sulphide and sulphur dioxide in the resulting sulphur vapour depleted gas stream takes place in a catalytic reactor (32). Sulphur is extracted in a further sulphur condenser (34). The resulting sulphur vapour depleted gas stream is passed into a catalytic reduction reactor (40) in which all the residual sulphur dioxide and any sulphur vapour are reduced to hydrogen sulphide. The resulting reduced gas mixture has water vapour extracted there from in a quench tower (52). The resulting water vapour depleted gas stream flows to a Claus plant for further treatment typically together with a second feed gas stream. Employing the catalytic Claus reactor (32) facilitates achievement of complete reduction of sulphur dioxide to hydrogen sulphide in the catalytic reactor (40) and therefore makes it possible to obtain high overall conversions of hydrogen sulphide to sulphur.

Abstract: A geographic tracking system (10) with minimal power and size required at the mobile terminal (18) collects observation data at the mobile terminal (18), forwards the data to a processor (11), which calculates the position. The mobile terminal (18) needs only to gather a few milliseconds of observation data (from 14-17), and to relay this observation data to the processor (11).  The range from the satellite (13) (or other airborne transponder) to the terminal (18) is determined using the known positions of an interrogating transmitter and a satellite (13), and a known terminal delay between the received signal and the transmission of the return signal, and the round trip time. An arc of locations is determined by computing an intersection of a sphere centered at the satellite (13) having a radius given by the calculated range with a model of the Earth's surface. The candidate points are considered and refined using code phase measurements from a set of GPS satellites (14-17). The candidate point having the lowest residuals or expected to measured code phases is chosen as the location of the mobile terminal (18). The measurements can be refined to account for various sources of error including measurement bias, relative motion and timing errors.

Abstract: La présente invention concerne un processus qui permet d'obtenir une masse particulaire à écoulement fluide, microporeuse et revêtue d'oxyde de métal de terre rare catalytique, la quantité d'oxyde de métal revêtu étant élevée, sans compromettre l'efficacité du matériau. L'oxyde de métal de terre rare déposé sur la surface externe peut représenter de 20 % à 70 % du poids du contenu total équivalent en matériau particulaire microporeux et en oxyde de métal de terre rare. En particulier, une masse particulaire à écoulement fluide zéolitique possédant des charges élevées d'oxyde de métal de terre rare tend à être assez stable. Par exemple, lorsque la masse particulaire à écoulement fluide zéolitique revêtue d'oxyde de métal de terre rare a été thermo-traitée à des températures inférieures à environ 200?0¿ C, puis mélangée en suspension épaisse dans de l'eau, habituellement moins de 30 % du poids d'oxyde de métal de terre rare ( du contenu total équivalent en oxyde de métal de terre rare) est retrouvé pour une lixiviation dans l'eau. On a découvert que ce matériau possède une lixiviabilité minimale lorsqu'il a été traité au dessus de 400?0 ¿C.

Abstract: A crystalline material sufficiently pure for use in pharmaceuticals may be made by forming a saturated solution of the material, changing the temperature of the solution so it becomes supersaturated, and subjecting the solution to irradiation by high intensity ultrasound, the frequency of the ultrasound being scanned over a range of frequencies. For example the ultrasound may be varied between 19.5 and 20.5 kHz, and this variation may be sinusoidal. Preferably the ultrasound is provided only briefly, say for less than 5 s, before allowing the solution to cool gradually without further irradiation. The ultrasound may be applied using a vessel with an array of ultrasonic transducers attached to a wall, so each transducer radiates no more than 3 W/cm2 yet the power dissipation within the vessel is between 25 and 150 W/litre. This method can reduce the metastable zone width to less than 10 K. It is applicable in particular to aspartame.
