Patent MX-9606191-A (MX)
Title: Coincident drop selection, drop separation printing method and system.
Inventor: SILVERBROOK KIA
IPC: B41J2/045
Filed: 1996-04-09
Abstract: Ink is contained under pressure in an ink reservoir. The ink travels to a nozzle, where it is retained in the nozzle by the ink surface tension. An equilibrium is created whereby no ink escapes the nozzle by ensuring that the ink pressure, plus a predetermined external electrostatic or magnetic field, is insufficient to expel the ink from the nozzle. The system can include a heater which is incorporated at the tip of the nozzle. When this heater is energized by a heater control circuit, the ink in contact with the nozzle tip is heated. Convection rapidly transports the heat over the ink meniscus. The ink is formulated so that surface tension reduces with increasing temperature. At an elevated temperature, the surface tension of the ink is reduced sufficiently that the equilibrium is broken, and ink moves out of the nozzle. At a predetermined time, the heater is turned off by the heater control circuit and the falling temperature causes the surface tension to increase. Ink continues to move out of the nozzle by its own momentum. Surface tension and the viscous flow limitation of the nozzle causes the ink drop to "neck" and separate from the body of ink. The ink drop then travels to the recording medium. The thermal drop on demand mechanism operates at low power, making construction of monolithic multiple nozzle print heads using a modified CMOS process practical. The print heads can include extensive fault tolerance to improve yield, device life, and reliability.

Patent MX-9606595-A (MX)
Title: Bag having protective patches.
Inventor: BRADY SEAN ALLEN
IPC: B65D75/26
Filed: 1995-06-28
Abstract: One or more patches (30, 32) adhered to a bag (21) have a first-patch-overhang-region (34) and a second-patch-overhang-region (36), wherein at least a portion of said first-patch-overhang-region is adhered to said second-patch-overhang-region. The overhang regions are preferably present on separate patches (30, 32) adhered to the bag. The patches (30, 32) can extend completely around the bag, eliminating uncovered regions, thereby providing protection against puncture by a bone-in meat product packaged within the bag. This "full width patch bag" has been discovered to be particularly beneficial in reducing punctures in the packaging of whole bone-in pork loins. Other bag embodiments without patch overhangs are also disclosed, for solving the bone puncture problem by providing alternative full width patch bags.

Patent MX-9707331-A (MX)
Title: Thrust washer for universal joint having preloading thrust surfaces.
Inventor: MYERS GERALD L
IPC: F16C21/00
Filed: 1997-09-25
Abstract: A thrust washer for use in a universal joint having a preloading thrust surface includes a center aperture, an outer surface, and an inner surface. A portion of the inner surface defines a thrust surface which contacts the outer end of the trunnion in only a limited contact area. The thrust surface may be located adjacent the outer circumference of the center aperture in the thrust washer . The thrust surface contacts only that portion of the outer end of the trunnion which is adjacent the outer circumference of the lubricant passageway extending through each trunnion. In one embodiment the inner surface is tapered outwardly such that the thrust surface is defined by the thickest portion of the tapared surface. Is another embodiment, the inner surface includes a plurality of protuberances located around the circumference of the center aperture such that these protuberances define the thrust surface. In both embodiments, a small preloading force is applied at the limited contact area on the trunnion which helps to reduce and/or eliminate any radial movement or play between the universal joint components. However, because the contact area is limited, the amount of preloading force is minimized such that the flex effort or torque required to causethe cross member to rotate within its bearing cups is not excessive. In both embodiments, the thrust washer is made from a resilient, deformable material which may be subject to wear such that the thrust surface may wear away after a short period of operation.
Patent MX-9709819-A (MX)
Title: Process for the preparation of 3-(methylthio)propanal.
Inventor: HSU YUNG C
Filed: 1997-12-08
Abstract: A process for the continuous preparation of 3-(methylthio)propanal. A liquid reaction medium is contacted with a gaseous acrolein feed stream in a gas/liquid contact zone. The reaction medium contains 3-(methylthio)propanal and a catalyst for the reaction between methyl mercaptan and acrolein. The gaseous acrolein feed stream comprises acrolein vapor and non-condensable gas. Acrolein is transferred from the acrolein feed stream to the reaction medium. Methyl mercaptan is introduced into the reaction medium and reacts with acrolein in that medium to produce a liquid reaction product containing 3-(methylthio)propanal. The non-condensable gas is separated from the liquid reaction product. The reaction product is divided into a product fraction and a circulating fraction, and the circulating fraction is recycled to the gas/liquid contact zone.

This is achieved by making all bandwidth in the upstream direction of the network (14) available for the purpose of course ranging. Once the whole network is ranged, then bandwidth is made available, in the normal way, to combined data communications and operations and management functions.
