Abstract: A feed device for transporting material from a remote location to a feed lower end of a transportation auger comprises a belt carried on a support frame with that support frame being stored in a stored position on top of the main auger tube. The auger tube carries a guide track with a support head movable along the track from a raised position at the top of the track to a lowered position at the bottom of the track. The support head pushes the feed device along the track to a deployed position beyond the lower end of the track at which the support head carries the upper end of the feed device and hold it at a position so that the feed material carried by the feed device is deposited at the lower end of the auger tube.

Abstract: A surface wave device filter comprises two 2-pole waveguide coupled double mode resonators (WCRs) electrically connected together in cascade. To permit narrowing of the filter passband for improved out-of-band rejection, e.g. for use of the filter as an intermediate frequency channel filter in a wireless communications system, whilemaintaining good matching for low ripple in the passband, a shunt capacitance isconnected in parallel with the static capacitances of the two WCRs. The shunt capacitance is constituted by interdigital fingers provided on the same piezoelectric substrate as one or both of the WCRs, perpendicularly to the WCR fingers to avoid surface wave interference, conveniently in space otherwise used by rails of the WCRs, optionally with oppositely phased fingers to cancel surface waves generated by these fingers. A capacitance can be similarly provided on the same substrate as any other type of surface wave device.

Granted: 2007-02-06
Abstract: A process for treating a light cracked naphtha to be used as an etherification feed stock is disclosed in which mercaptans, hydrogen sulfide and diolefins are removed simultaneously in a distillation column reactor (10) using a reduced nickel catalyst. The mercaptans and hydrogen sulfide are reacted with the diolefins to form sulfides which are higher boiling than that portion of the naphtha which is used as feed to the etherification unit. The higher boiling sulfides are removed as bottoms (8) along with any C6 and heavier materials. Any diolefins not converted to sulfides are selectively hydrogenated to mono-olefins for use in the etherification process.

Abstract: A method of controlling transmission power of a plurality of base stations associated with a mobile unit in a CDMA (code division multiple access) cellular system, is disclosed. The mobile unit communicates with one base station among the plurality of base stations. According to the present invention, power of each of pilot signals respectively transmitted from the plurality of base stations is measured at the mobile unit. Following this, information about a measured power value of each of the pilot signals is transmitted to the one base station. Thereafter, a first power control coefficient is determined at the one base station. The coefficient is a ratio of total pilot power values of the plurality of base stations, other than the main base station, to a pilot power value of the one base station. Subsequently, the transmission power of each of the plurality of base stations using the first power control coefficient is controlled.

Abstract: In a battery pack made up of battery cells encased within a housing made up of a stronger outer housing portion and a weaker inner housing portion, the battery cells are secured to the stronger outer housing portion. Advantageously, the relative motion between the battery cells and the stronger of the housing portions that results when prior art battery packs are dropped, and which causes catastrophic failure of the prior art battery packs, is prevented. The battery cells may be secured to the stronger outer housing portion, for example, by gluing the battery cells to the stronger housing portion, attaching the battery cells to the stronger housing portion by using double-sided sticky tape, molding features into the stronger housing portion that immobilize the battery cells adjacent to the stronger housing portion, or providing screw holes through the stronger housing portion so that screws may engage the battery cell or an appendage thereto.

Granted: 2005-11-22
Abstract: The invention relates to a method for programmed control of a home and building automation system (30) by means of standard programs and of sensors (40) for monitoring persons (12) room by room. In order to save energy and increase comfort, the automation system triggers actuators (52) of installations (24) or groups of installations as needed. By means of adaptive, self-teaching algorithms in the software, the systematic and stochastic behavior of one or more persons (12) in the respective room, and throughout several rooms, is stored continuously. These algorithms adapt themselves automatically, and trigger actuators (52) in combination with adjustable, deterministic algorithms. The room-oriented optimization algorithms are grouped into one algorithm, incorporating external parameters, that optimizes the automation system holistically. The individual room algorithms are adapted retroactively accordingly. The self-teaching process is controlled by signals from the presence-monitoring and activity-monitoring sensors (40). At least one sensor (40) is located in each room for presence and activity monitoring of persons (12). These sensors are link ed up to presence and activity controlled closed-loop control circuits (32). These networks, preferentially of the neuronal type, with computers (34) include in their software adjustably implemented, deterministic and adaptive, self-teaching algorithms.

Abstract: A hot runner nozzle structure provides insulation to reduce heat transfer to a utilizing tool and to increase accuracy of temperature measurement and control. A shaft foot of extremely low heat conductivity is used to separate a point of contact between a feed tube shaft and the tool. The shaft foot may be formed of titanium for example. An insulating cap of extremely low heat conductivity surrounds the shaft foot in the vicinity of the nozzle tip. The cap may be formed of PEEK or of titanium for example. Gaps may be provided between the insulating cap and shaft foot and/or between the shaft foot and feed tube shaft. In an alternate embodiment having smaller dimensions, an insulating ring is provided at the end of the feed tube shaft. The structure, combined with a compound body surrounding the feed tube shaft and stabilizing the heater unit, permits placing a heat sensor extremely close to the nozzle tip in order to obtain more accurate temperature control.
