Patent CA-2293136-A1 (CA)
Inventor: BARSY PATRICK G
IPC: B64F5/30
Filed: 1999-12-17
Abstract: A parked or stored, fixed or rotary winged aircraft, utilizing piston type or gas turbine powerplants, and/or hydraulic powered flight controls, requires an aircraft diaper that wraps an absorbing material to the underside of said powerplant nacelles or aircraft fuselage. Said diapers purpose is to capture and retain aircraft systems fluids that, from time to time, vent overboard or leak from gaskets, packings, seals, lines, fittings, drain tubes, tanks or reservoirs. As well, if a major fluid spill is encountered while servicing or maintaining said aircraft fluid systems, said diaper can be used to assist in the capture and containment of these fluids, thus preventing or rectifying point source contamination of the environment from these petroleum based fluids. This aspect becomes more prevalent for aircraft operating at remote, austere locations or in delicate ecosystems.

Title: Hybrid construction luggage case
Inventor: ALEXANDER WENDELL CHRISTOPHER
IPC: A45C5/06
Filed: 2000-01-25
Abstract: The present invention relates to two-wheeled luggage cases 10 formed of substantially two parts, the base shell 24 of a generally one-piece molded plastic construction, the lid shell 30 of a composite construction primarily of textile fabric panels assembled to form a covering that provides an access to the interior of the case. Properly fitting a generally textile constructed lid to the integrally molded sides of a base shell is difficult, especially if the case is large, and most especially where the lid shell is constructed at a location remote from where the lid and base shell are joined to integrate the two and form the overall luggage case.  Accordingly, the disclosed luggage case has a body portion which comprises a base shell primarily formed of a one-piece molded plastic outer unit having a bottom, peripheral walls extending up from the bottom to define an interior volume to contain the user's things, and a lid shell is affixed to the base shell, the lid shell being mostly formed of fabric materials, and having a peripheral edge portion and an access opening. Means are provided for permanently affixing the peripheral edge portion of the lid shell (Figure 7) to the peripheral edge of the base shell, the means for permanently affixing including a first elongated extrusion 55 sewn along a peripheral edge portion of the lid shell, an outwardly facing groove molded into the base shell adjacent and parallel to the peripheral edge of the base shell, and fasteners 40 passing through the edge portion of the base shell and through the first elongated extrusion. The case also includes straps 32 attached to the base shell that extend perpendicular to the peripheral edge of the base shell and around the lid shell to help provide a strong connection between the lid and base shell.

Title: A double molding process whereby a sign is produced on a product while said product is molded
Inventor: PETIT JIMMY
IPC: G09F3/00
Filed: 2000-03-03
Abstract: A double molding process whereby at least one sign is produced on a product while the product is molded. The product has an inner core and an outer cover. In the process, the inner core is molded with a first molding material. The inner core has at least one side provided with a groove in the shape of the sign to be produced. The inner core also has at least one other side provided with at least one channel leading within the inner core to the groove. The outer cover is then molded onto the inner core with a second molding material in such a manner that the one side of the inner core is not covered by the second molding material and thus remains visible. The channel of the other side and the groove of the one side are both filled up with the second molding material to produce the sign on the side of the product. This double molding process allows production of a sign, such as a name, a number, a logo, a trademark, or any other type of symbols conveying information, on a product while the product is molded, the sign lasting all throughout the working life of the product by virtue of its construction.

Title: Recording head, substrate for use of recording head, and recording apparatus
Inventor: IMANAKA YOSHIYUKI
IPC: B41J2/05
Filed: 2000-06-08
Abstract: A recording head comprises a plurality of recording elements for performing recording; a driving circuit for driving the plurality of recording elements; and a predetermined voltage generating circuit for generating a predetermined voltage to be applied to the plurality of recording elements from voltage supplied from outside. With the head thus structured, a desired voltage is generated in the interior of the head by use of the predetermined voltage generating circuit for performing recording, thus making it possible to prevent the voltage drop which may take place if the voltage is supplied from outside through a cable, as well as to prevent the durability of the heat generating elements from being damaged due to noises. It also becomes possible to set the voltage to be applied to the recording elements at an optimal value corresponding to the discharge voltage, hence stabilizing ink discharges efficiently.

Title: Load sensor having an annular gauge ring
Inventor: LEHTOVAARA JORMA J
IPC: G01L5/10
Filed: 1998-11-20
Abstract: Load sensor having an annular gauge ring comprising an annular inner ring portion and an annular outer ring portion. The gauge ring has strainable beam members and flexing beam members. The beam members interconnect the ring portions. The flexing beam members are thicker in comparison to the strainable beam members so that the flexible beam members are less subject to elongation and compression due to strain in comparison to the strainable beam members. The strainable beam members are constructed and arranged such that the substantially isolated relative movement between the ring portions creates a strain in the load measuring direction in the strainable beam members. A strain measuring an outputting device is adapted to measure the magnitude of the strain and hence the applied load. The load sensor is particularly well suited for measuring belt tension in both idler and torque transmitting pulley assemblies. Also, the load sensor may be used to measure the co-efficient of friction between a bushing and an oscillating shaft.

Inventor: LUNDBY STEIN A
IPC: H04J13/00
Filed: 1998-11-30
Abstract: A method and apparatus for providing diversity transmissions to a receiving unit. A transmitting station used to communicate with the receiving unit may have a first and second antenna (34, 36) and repeatedly switch between the two antennas (34, 36) during the transmission of information to the receiving unit. Transmission of information may be initiated from a first antenna (34), and when terminated, transmission of information from a second antenna (36) is initiated. Likewise, after transmission of information from the second antenna (36) is terminated, transmission of information from the first antenna (34) continues. This "swapping" of antennas continues until the information transfer ends. Antenna swapping results in diversity transmissions that improve the ability of the receiving unit to receive a coded and interleaved information transmitted from the transmitting station.  The interleaver may disperse the encoded symbols in each antenna dwell period such that decoder decisions are based on a mix of symbols from each antenna.
