Patent MX-9703419-A (MX)
Title: Ink jet printer with sensing system for identifying various types of printhead cartridges.
Inventor: DIETL STEVEN J
IPC: B41J2/175
Filed: 1997-05-09
Abstract: A printhead cartridge identification system is disclosed which ensures that an ink jet printer operates only with ink jet cartridges compatible with the specific printer function. An ink container which supplies ink to an associated printhead has a light reflector incorporated into a transparent wall of the ink container housing. The cartridge, comprising the ink container and associated printhead, is mounted on a scan carriage. Periodically, the carriage is conveyed to an optical station comprising a light source and a photosensor. The light source is energized and a beam of light is directed towards the reflector. In one embodiment, the reflector has two angled reflective facets made of a first or second particular reflective material. Light from the light source is reflected from the first to the second facet and then to the photosensor. Depending upon the specific material, the reflected lighted has a first and second level of reflected light intensity, and the photosensor will generate a signal of a corresponding first and second level of intensity. The photosensor outputs are sent to a cartridge identification circuit in the system controller where the signals are compared to previously stores signals associated with a specific type of cartridge. If a cartridge ID is made, printer operation is enabled. In another embodiment, the cartridge which is brought to the optical station must have the reflective elements at a location such that the light beam from the light source is redirected to the photosensor. If the cartridge has the reflectice elements at a higher or lower location then the light source, no signal will be sent to the photosensor, and the cartridge ID will not be made.

Title: A process for austempering ductile iron.
Inventor: LIU XIAOJUN
IPC: C21D1/20
Filed: 1997-11-04
Abstract: As process for austempering ductile iron includes austenitizing a ductile iron casting of low alloy content followed by quenching the workpiece for a controlled period of time in a quench medium such as water, an aqueous polymer solution or a medium speed quench oil. The workpiece is then austempered in an air tempering furnace, resulting in a ausferrite microstructure essentially free of pearlite and martensite, and with mechanical properties meeting ASTM designation A897-90 "Standard Specification for Austempered Ductile Iron Castings." The process eliminates the need for a molten salt bath for quenching and tempering.

Abstract: 1,180,496. Natural gas liquefaction process. CHICAGO BRIDGE & IRON CO. 20 Feb., 1968 [27 July, 1967], No. 8221/68. Heading F4P. Liquefaction of compressed natural gas containing carbon dioxide, methane and higher hydrocarbons is effected by dividing the feed gas into first and second streams 12, 30 cooling the first stream by work-expansion in a turbine 18 without solidification of carbon dioxide, absorbing carbon dioxide at 31 from the second stream 30, cooling the latter to effect partial liquefaction in heat exchangers 24, 23, 22 in countercurrent to said expanded first stream, separating at 62 an impure liquid fraction containing heavy hydrocarbons from said cooled second stream, expanding this separated liquid at a valve 64 and using the cold so produced in a terminal exchanger 67 to liquefy vapour withdrawn from the separator 62 through a line 70. Most of the liquid methane is expanded at a valve 72 into a storage tank 74 at about atmospheric pressure whilst a minor portion of liquid methane is expanded at a valve 77 and joins the cold vapour leaving valve 64. A phase separator 44 is interposed in the second stream between exchangers 24, 23 and separated higher hydrocarbons are expanded at a valve 48 whilst a portion of the uncondensed vapour is withdrawn through a line 45, expanded in a turbine 37 and the two portions combined in a line 50 with the aforementioned expanded portions from separator 62. Effluent from tank 74 is compressed at 79, added to the first feed stream leaving turbine 18 and is then warmed in exchangers 22, 23, 24, 13 and fed into a consumer line 26.

Title: Magnetic tape recorder - with tape transported on two spools in two directions has belt drive with common flexible belt
IPC: G11B15/60
Filed: 1975-04-16
Abstract: On both sides of the transmitting heads there are driving pulleys which are driven from the driving shaft of the main drive via a belt drive with a common flexible belt in such a way that the belt runs in the direction of the tape from the driving shaft to the front driving pulley, thence to the rear driving pulley and from there back to the driving shaft. As a result of the belt tension increasing from the front to the rear driving pulley, the rear pulley is forced to drive the belt more quickly than the front pulley, so that the tape has a constant tape tension at the transmitting heads between the driving pulleys.

Patent NL-8004597-A (NL)
IPC: H02P9/42
Filed: 1980-08-14
Abstract: A method and an installation are described for the optimum use of at least one variable power source which is difficult to control. In known power systems with a power source which is difficult to control, it is normal to couple to it one or more synchronous A.C. generators which can be connected with a rectifier and an inverter to an autonomous A.C. network. In this arrangement, the A.C. network is connected to a second synchronous A.C. generator which is mechanically connected, such that it can be disconnected therefrom, to a controllable auxiliary machine, such as e.g. a diesel generating set. To keep the frequency of the network constant if too much power is offered or, above all, if the power offered drops, such an amount of power is supplied from the autonomous A.C. network (5) to an additional usable load (2) that the frequency of the network (5) remains constant. The excess power to be diverted can be used, for example, for the preparation of hot water or for the electrolysis of water, combined with the use of fuel cells, or for battery charging or for pumping water to increased heights. <IMAGE>

Title: Activated carbon prodn. - using lignite ash from power station boiler and heat from flue gases
IPC: C01B32/336
Filed: 1982-09-29
Abstract: Prodn. of activated carbon is integrated directly into the plant of a thermal power station. The activator appts. is supplied directly with ash xylite prepared from combustion residues of the boiler and also receives a partial stream of the flue gas to provide heat. The gases discharged from the activator appts., together with their suspended constituents, are blown directly through the coal dust mill into the boiler furnace, where the heat from them is utilised. A conventional activator appts., p.g. a rotary kiln or fluidised bed appts., is used, requiring no special construction measures. The heat utilisation, by contrast, is rendered very economical by providing the basic supply of heat to the appts. from flue gases obtd. from the power station and therefore using combustion gas only for regulating the temp.

Title: Buffer-type roller conveyor - has pressure rollers controlling drives in adjacent sections to prevent crate collision
IPC: B65G47/26
Filed: 1985-01-31
Abstract: The crate-handling roller buffer is in sections each roughly the length of a crate, while a lengthwise motor-driven shaft runs below the rollers. Other rollers coupled together by belts are brought into engagement with the shaft and track rollers to transmit the drive to the latter, this being cut in and out in successive sections. A pressure roller protrudes above the track when no crate is present and one or more stops are also movable up and down. The driving rollers are actuated by a first rod (30) coupling the pressure roller (18) to the rod (14) on which the driving rollers are mounted in a particular track section, while a second rod (36) coupled the pressure roller to the next section in the travel direction (P) of the crates and a third rod (34) to the preceding one. Thus the drive to the rollers in a particular track section is cut out as long as there is a crate in it and the preceding one holding the pressure rollers down.
