Patent CA-2163369-A1 (CA)
Inventor: MOYNIHAN EDWARD R
IPC: H01L41/257
Filed: 1995-03-17
Abstract: In the embodiments of the simplified ink jet head described in the specification, a carbon body is formed with ink passages, such as internal passages (19, 21, 25) extending through a carbon plate (26), pressure chambers (2) on one side of a carbon plate (26), flow-through passages (24) on the other side of the same plate and ink supply passages (19, 25), and a piezoelectric plate (23) is affixed to the pressure chamber side of the carbon plate by a thin layer of epoxy adhesive. The piezoelectric plate (23) may have a conductive coating on one side which is photo-etched to produce an electrode pattern corresponding to the pattern of the pressure chambers in the carbon plate. An orifice plate (13) may have specially profiled orifice openings (12) to assure axial projection of drops and may be affixed by a thin layer of epoxy adhesive to a carbon plate (26) having orifice passages (21) supplying ink from the pressure chambers (20) to the orifices (12). Since the carbon plate is conductive, it can be used, if desired, as an electrode on the opposite side of the piezoelectric plate (23) and, to assure grounding of  the piezoelectric plate, a conductive epoxy adhesive may be used to bond the piezoelectric plate to the carbon plate. Moreover, since the carbon plate is porous, it can provide a communication path (76) between a vacuum source (77) and an air-permeable, ink-impermeable layer (75) on the ink passages to remove dissolved air from the ink in the passages. In one alternative embodiment, an ink jet head assembly contains two separate carbon pressure chamber plates, a carbon manifold plate and a carbon collar to retain the carbon plates in an assembly, (Fig. 6)

Inventor: LEE JOO MIN
IPC: A47G29/122
Filed: 1996-03-25
Abstract: When driving and looking around for an unknown place, one looses the sense of direction. Everything in today's society has evolved with time except for theconcept of where the address numbers are located on the house or the building. Because there is no specific location for the address to be placed, it makes it very hard for the person to find it. Trying to drive at a fast pace, maybe even driving in the dark, looking back and forth to locate and read the addresses, is difficult. These are the frustrating reasons why I came up with this idea to improve the concept of the Reflective Triangular Lights and Mailbox. Since it is relevant enough to say that all houses and buildings are not built the same, so I have created an invention where the address numbers are placed on a certain mailbox. With the Reflective Triangular Lights and Mailbox, it makes it much easier for whoever wishes to locate addresses while driving, even in the dark.

Title: Apparatus and Method for Adding and Removing a Base Station from a Cellular Communications System
Inventor: WEAVER LINDSAY A JR
IPC: B60S5/04
Filed: 1995-09-12
Abstract: An apparatus and method for adding and removing a target base station from a network of base stations, which includes base stations adjacent the target base station. The apparatus is comprised of two attenuators: a first for setting an artificial receive noise power level and a second for setting a transmit level. The transmit level determines the forward link coverage area of the base station. The artificial noise level sets the reverse link coverage area of the base station. When a base station is added, initially the transmit power is low and the artificial receive noise power is high such that the forward and reverse link coverage areas are collocated in close proximity to the base station. As the base station blossoms into full operation, the artificial receive noise power is decreased and the transmit level is increased such that the two coverage areas of the base station remain balanced as the coverage areas expand. When a base station is to be removed from a system, the same attenuators are used to wilt the two coverage areas in unison as the power level transmitted from the base station decreases.

Title: Papermakers fabric with flat high aspect ratio yarns
Inventor: LEE HENRY J
IPC: D21F1/10
Filed: 1991-03-15
Abstract: The present invention is directed to a papermakers fabric which provides for usage of high aspect ratio yarns as structured weave components. The fabric comprises a system of flat monofilament machine direction yarns (hereinafter MD yarns) which are woven in a selected weave construction which provides stability to the fabric. In a preferred embodiment, the system of MD yarns comprises upper and lower yarns which are vertically stacked. Preferably, the upper MD yarns define floats on the upper surface of the fabric and each upper MD yarn is paired in a vertically stacked orientation with a lower MD yarn. the lower MD yarns may weave in an inverted image of the upper MD yarns to provide floats on the bottom fabric surface or may weave with a different repeat to provide a different surface on the bottom of the fabric.             At least the upper MD yarns are flat monofilament yarns woven contiguous with each other to reduce the permeability of the fabric and to lock in the machine direction alignment of the stacking pairs of MD yarns. In the preferred embodiment, the same type and size yarns are used throughout the machine direction yarn system and both the top and the bottom MD yarns weave contiguously with adjacent top and bottom MD yarns, respectively. The stacked, contiguous woven machine direction system provides stability and permits the MD yarns to have a relatively high aspect ratio, cross-sectional width to height, of greater than 3:1.

IPC: H01M50/107
Filed: 1996-04-15
Abstract: The incidence of leaks in crimp sealed electrical devices comprising thermoplastic gaskets can be substantially reduced by preforming the gaskets about the device covers at elevated temperature prior to crimping.   The method prevents the formation of cracks in the gaskets which occur especially in crimping operations involving substantial deformation of the gaskets.   The method is particularly suited for use in non aqueous lithium batteries wherein the gaskets  are typically substantially deformed around complex covers.

Title: Polyoxyalkylene polyether monool polyurethane foam additive
Inventor: PATTERSON JIMMY L
IPC: C08J9/14
Filed: 1996-04-16
Abstract: There is now provided a polyol composition containing a polyol having polyester linkages, an aliphatic or cycloaliphatic C4-C7 hydrocarbon blowing agent, and a polyoxyalkylene polyether monool initiated with a C8-C24 fatty hydrocarbon having one alkylene oxide active hydrogen atom. We have found that the monool emulsifies the C4-C7 blowing agent in the compound having polyester linkages, to form an emulsified polyol composition, after which an organic aromatic isocyanate may be reacted with the emulsified polyol composition to form a closed cell polyurethane foam. The polyol composition is used to make rigid closed cell polyisocyanate based foams which are dimensionally stable, and have good insulation values and flame retardance. Combining the monool with the polyester based polyol produces a foam having a density lower than that of a reference foam made with the same ingredients and amounts except in the absence of the monool. Whether the monool is merely mixed with the polyol or used to form an emulsion with the hydrocarbon blowing agent and the polyol, the foam density may be lowered when the monool is used.
