Abstract: A modular telephone plug (110) having an elongated dielectric housing (112) and a clip member (123, 284) attached that is adapted to fit into a standard RJ-type jack. More specifically, one end (114) of the modular plug (110) defines an electrical connector section to which wires from a telephone cord (120) can be attached.     For this purpose, the housing (112) includes an internal channel (143) through which the telephone cord (120) can extend. The clip member (123, 284) is secured in a cantilevered manner at an end (116) of the housing (112) remote from the electric connector section. The housing (112) is also formed with a recess (220) into which extends a free end (276, 313, 380) of the clip member (123, 284). The modular plug (110) has an associated length of 1.1 to 1.5 inches (approximately 2.8 to 3.8 cm). With this construction, the modular telephone plug (110) can be easily grasped and manipulated.

Abstract: An intubator includes a housing and a memory cylinder connected for axial movement relative to the housing.  A flexible scope tube attached to the housing extends within and through the memory cylinder such that the scope tube can be retracted within or caused to extend beyond the distal end of the memory cylinder by the relative axial movement between the housing and memory cylinder.  The scope tube is angularly adjustable and includes a light transmitting  fiber  optic  cable,  a  visual  transmission fiberoptic  cable,  and  a  fluid  conduit.    In  use,  an endotracheal tube is mounted on the memory cylinder such that the endotracheal tube, memory cylinder and scope tube have their distal  ends  flush.   The  intubator is  then inserted through the patient's mouth to the larynx opening. Collapsing the memory cylinder within the handle causes the scope tube to be extended from the memory cylinder for positioning within the trachea.  The endotracheal tube can then be located within the trachea using the scope tube as a stylet or guide.

Abstract: A pre-metering rod is located between a coating applicator and an air knife, and replaces the smoothing roll in some existing air knife applications. The pre-metering rod consists of a small diameter rod of about one and one-half inches in diameter that rotates at 10-500 rpm against the direction of the coating layer on the web. The web is wrapped around a portion of the circumference amounting to about twenty-five degrees of the rod's surface as it travels over the rod. The rod is supported in a rod holder supported on a support beam. Actuators move the support beam away from the web for threading and maintenance, and towards the web to engage the rod with the web. The combination of the rod diameter, the amount of wrap on the rod, and the speed of the rod rotation determine the amount of pre-metering of the coating, which determines the thickness of the coating layer on the web that is presented to the air knife section. As a result, the thickness of the coating layer can be decreased. Decreasing the mass of the coating presented to the air knife decreases the momentum of the coating layer and allows the speed of the web to be increased to over 2,000 feet per minute as it passes through the air knife section.

Title: Method and apparatus for achieving fabric independent routing technique
Inventor: ASH GERALD RICHARD
IPC: H04Q3/00
Filed: 1998-03-31
Granted: 2002-09-24
Abstract: The routing of calls in a telecommunications switching system (12 1, 12 2) comprised of one or more fabrics (22 1, 22 2, 22 3) controlled by corresponding fabric controllers (26 1, 262 and 26 3, respectively) is carried out by a routing processor (28) independent of the fabrics. The routing processor actually selects the route for each call by specifying a channel to a neighboring switching system to carry the call. Further, the routing processor has the capability to respond to queries from other switching systems regarding trunk group status and traffic load to enable the processor to assist the routing processor of the other switching system to make routing decisions. By implementing fabric independent routing, routing processing is re-used for new fabric capacity, and is readily extended to accommodate new service types, such as bursty data services.Fabric independent routing achieves lower development cost by avoiding redevelopment of routing functions on new fabric controllers, as they are added, and the addition of new routing features is made on a single routing processor function versus multiple fabric controllers. Fabric independent routing allows routing processing to be implemented on processors with essentially unlimited real-time and memory resources by riding the processor technology curve, and achieves performance advantages such as reduced call set up delay and improved overall switch reliability.

Title: Balanced transversal i,q filters for quadrature modulators
Inventor: DENT PAUL W
IPC: H04B1/707
Filed: 1997-03-13
Granted: 2004-11-23
Abstract: Radio transmissions are spectrally contained to reduce adjacent channel interference by a method and apparatus for I, Q filtering of signals before quadrature modulation in digital cellular radio transmission systems such as communications systems following the GSM TDMA, IS-54 or IS-95 standards. The filtering is accomplished by multiple stage registers connected at their complementary outputs to identical resistor networks. The outputs of the resistor networks are summed to represent a smoothly transitioning analog representation of the digital voice or data transmission. The analog representation may be additionally low pass filtered to remove higher frequency components before quadrature modulation. Because rapid transmissions in the transmittal signal are avoided, adjacent channel interference is reduced.

Strand through passages are provided through the rotatable head, for drawing the strand wires therethrough, without being coated. The strand wires are stranded about the core in a closing die. Preferably, the powder circulation circuit is a closed circuit, enabling recycling of the powder. The powder is preferably fluidized prior to its delivery to the applicator, and is withdrawn from the applicator under a slight vacuum. The rotatable head may include a filling compound applicator section and a powder applicator section, which are connected to each other so that they rotate together. Methods of applying filling compound and water absorbing powder are also described.

Abstract: An integrated system utilizing a solid oxide fuel cell and at least one ion transport reactor to generate electric power and a product gas by delivering an oxygen-containing gas, typically air, to a first cathode side of the solid oxide fuel cell and delivering a gaseous fuel to a first anode side. Oxygen ions are transported through a membrane in the fuel cell to the first anode side and exothermally react with the gaseous fuel to generate electric power and heat. The heat and oxygen transport produces a higher-temperature, reduced-oxygen-content gaseous retentate stream exiting the cathode side of the solid oxide fuel cell which is delivered to a first ion transport reactor where a substantial portion of the residual oxygen is transported through an oxygen selective ion transport membrane. A product gas stream is then recovered.
