Abstract: A method for compensating for capacity overload in a communication system by first determining the received signal power level at a base site (62) is described. The power level is compared with a threshold power level (63). If the received power level is greater than the threshold, the signal-to-noise ratio for the system is reduced (65). With the acceptable signal-to-noise ratio reduced, the subscriber power will be reduced. The received signal power level at the base site will then return to the threshold level. Alternatively, a signal-to-noise ratio of a pilot signal can be determined (62) at the base. The signal-to-noise ratio is compared to a threshold signal-to-noise ratio (63). If the signal-to-noise ratio of the pilot is less than the threshold, the threshold level is reduced (65). With the acceptable signal-to-noise ratio reduced, the subscribers are directed to reduce their power.

Granted: 1999-08-31
Abstract: The combination of an intake air supply system with an internal combustion engine (10) having a charge air cooler, a cylinder charging air intake and an exhaust discharge is provided. The intake air supply system includes a Roots-type positive displacement blower (37) having inlet (38) and outlet (40) means and an exhaust gas driven turbo-compressor (41) connected in series with the blower (37). The intake air supply system further includes a bypass passage (58) connecting the blower inlet (38) and outlet (40) and a valve (54) in the bypass passage (58) to control the flow of fluid through the bypass (58).  The valve (54) inoperative to open and close the bypass passage (58) in response to engine operating parameters and to modulate the flow area of the passage; (58) in response to the same engine operating parameters so as to infinitely vary the flow area between the open and closed positions of the valve (54). The valve (54) is modulated to operatively maintain the bypass passage (58) at least partially open at engine idle, whereby the valve means (54) permits bypass flow to recirculate air flow from the blower outlet (40) to the inlet (38) to reduce ar limit the engine power absorbed by the blower (37) or to conduct additional air flow around the blower (37) directly from the turbo-compressor (41) to the engine intake to avoid the restriction of the blower (37) to increased charging air flow. A single valve means thus provides a dual function capability.

Patent CA-2127311-C (CA)

Granted: 1999-04-20
Abstract: ABSTRACT A food container which is a combination of a base portion and a lid portion made from a resilient polymeric material is disclosed. The base is a unitary component including an upwardly projecting, peripherally extending sealing rim having inner and outer sealing areas. The lid is also a unitary component including a peripherally extending sealing channel correspondingly shaped to receive the sealing rim of the base and particularly, to engage the rim at the inner and outer sealing areas. Because both the base and lid are made from resilient material, the inner and outer sealing areas are shaped to provide a self-reinforcing seal configuration wherein the initial engagement of either the inner or the outer seals urges the other seal into engagement. This feature also permits a wide tolerance to processing variations in the size of the lid and the base. The base portion of the food container of the present invention is also designed to include audible indicators as the lid becomes fully sealed with the base. Further, the container is suitable for microwave cooking.

Title: Method of fabricating a tubular cell window covering with undulations along the length of the cells and the resultant product
Inventor: SWISZCZ PAUL G
IPC: E06B9/262
Filed: 1994-07-07
Granted: 1998-01-06
Abstract: An expandable and contractible tubular cell window covering includes a plurality of contiguous cells which have been bonded together to form a wavy or undulating pattern along the length of the cells.  The undulating or wavy patterns can be created by initially stretching the cells  before  bonding  adjacent  cells  and  subsequently releasing the stretch so that the fibers engaged with the bonding medium remain in a stretched or separated condition while the remaining fibers are relaxed.  The cells can also be bonded with an adhesive that expands on curing to create the same effect without having to prestretch the fabric before applying the bonding medium.  In a third embodiment of  the  invention,  adjacent  tubular  cells  are  bonded together with curved lines of adhesive which again create an undulating or wavy configuration along the length of each tubular cell.   The methods for forming the window covering is also disclosed.

Title: Child restraint seat
Inventor: HOLDAMPF CARL J
IPC: B60N2/30
Filed: 1994-08-01
Granted: 2004-07-13
Abstract: The present invention is directed to a "fold-out" or integral child restraint seat having a mechanism interconnecting a headrest member and a seat member for causing coordinated movement therebetween. When it is desired to deploy the integral child seat, the headrest member is automatically moved to its raised operative position in coordination with movement of the seat member to its lowered operative position. Conversely, when it is desired to stow the integral child seat, the headrest member is automatically moved to its lowered storage position in coordination with movement of the seat member to its raised storage position. As a result, movement of the integral child seat between its stowed and deployed positions can be accomplished in one operation for substantially enhancing the convenience afforded to the person attempting such movement. The integral child seat also provides an improved latching mechanism that is operable for positively retaining the integral child seat in both of its stowed and deployed positions.

Title: Method of manufacturing moulded articles
Inventor: NICOLAY ALBERT
IPC: B27N5/00
Filed: 1995-05-15
Granted: 1999-02-23
Abstract: Described is a method of manufacturing moulded parts, preferably having the same wall thickness, from mixtures of cellulose and/or lignocellulose fibres with more than 20% by weight of thermal binders, in which the moulded article results from application of heat and pressure to fibre mat prefabricated therefrom. In a first step  the fibre mat undergoes preliminary compression as a planar, endless matted fibre fleece, with only a small degree of compression of the fibre composite, the matted fibre fleece containing at least 2% by weight of a binder which cross-links under heat, its "start-off temperature", i.e. the temperature at which cross-linkage begins, being lower than the softening temperature of the thermoplastic binder. The cellulose and/or lignocellulose fibres are provided, before production of the fibre composite, with a surface finish of the cross-linking binder. The fibre mat, slightly compressed in the first step, is in a second step heated in the form of a blank or of a web to at least the start-off temperature of the fibre finish. Compression is carried out before shaping of the moulded article, which is held in this condition of density for the duration of the cross-linkage of the fibre finish.     Finally the finally-compressed, preferably planar fibre mat, heated to the softening temperature of the thermoplastic binder, is shaped by the application of pressure to form the finished moulded article, in a press tool whose temperature lies below that of the heated fibre mat.
