Abstract: A device and method for assigning a channel in a CDMA communication system.  According to an embodiment of the present invention, in a channel assigning method for a base station, the base station determines the states of orthogonal codes and quasi-orthogonal code masks when a channel is assigned, selects an available quasi-orthogonal code mask number and orthogonal code index if it is determined that a quasi-orthogonal code should be used, and generates the quasi-orthogonal code. Then, the base station assigns the generated quasi-orthogonal code to a forward link dedicated channel, generates a channel assignment message, and transmits the channel assignment message on a different channel to a mobile station.

Abstract: The invention relates to a device for receiving and transporting objects, the device having at least one pair of parallel chains or belts situated opposite each other and driven in synchrony, which define a space between each other for transporting the objects therethrough. Each chain (2) has at least one gripper (10) which is mounted so as to be pivotable thereon and faces one of respective grippers on the other chain. Furthermore each gripper has an extension (13) which is moveable along a guiding path (61, 62, 63, 64), the respective guiding path having a path section (62) sloped with respect to the direction of transport of the objects (7) at the point of receipt of the objects, so that, when the chain is moving, the extension (13) of the gripper (10) is deflected along the sloped path section (62) and thus a rotational movement countering the translation movement (arrow A) caused by the chain is imparted to the gripper. Thus no rotational movement occurs at the moment of contact between the gripper and the object.

Abstract: Blood processing systems (10) and related methods place first (PP1) and seco nd (PP2) fluid actuated pump stations in in-line communication between a source and a destination. The systems and methods apply fluid pressure pump strokes to the first and second pump stations to convey fluid from the source to the destination. The systems and methods switch between a first flow mode and a second flow mode. The first flow draws a fluid volume into t he first pump station from the source and expel a fluid volume from the second pump station to the destination. In the second flow mode, the pump strokes draw a fluid volume into the second pump station from the source and expel a fluid volume from the first pump station to the destination. The pump strokes are synchronized so that flow from the source is essentially continuous while fluid flow to the destination is pulsatile.

Abstract: Process for manufacturing a welded pipe from a metal strip having two longitudinal edges approximately parallel to each other, which are brought together so as to come approximately into contact with each other and thus form an unwelded pre-tube. The two edges are then welded together to obtain a welded metal pipe by using a hybrid arc/laser welding process in which at least one laser beam and at least one electric arc are used approximately simultaneously. This process can be used to produce weld seams of rectilinear, helicoidal or spiralled shape.

Abstract: An electrical current collector system includes a rotatable shaft (28); an electrically conductive slip ring (27); and a slip ring support assembly (42). The slip ring support assembly (42) comprises plural post insulators (102) spaced radially about the rotatable shaft for attaching the conductive slip ring to the rotatable shaft. The post insulators facilitate adjusting of the position of the slip ring relative to the rotatable shaft, e.g., to provide concentric positioning. The post insulators comprise an attachment/adjustment assembly (106) for connecting to the slip ring. In one embodiment, the attachment /adjustment assembly comprises a spring plate (134) which is adjustably biased to provide a preloading displacement that absorbs differential movement due to temperature changes of the slip ring an the rotatable shaft. In one example deployment, the current collector system is provided as part of a rotary transformer system (20) which, e.g., transfers electrical power between a first electrical system (e.g., first electrical grid) and a second electrical system (e.g., second electrical grid).

Title: Toilet tank with sediment removal assembly
Inventor: SCHUSTER MICHAEL
IPC: E03D1/00
Filed: 2001-09-27
Granted: 2008-12-09
Abstract: A toilet tank with a sediment removal assembly comprises a flexible tube connected to the upper discharge spout of the intake standpipe in the toilet tank cavity, and a configured length of coppertubing connected to the flexible tube for water to flow therethrough when the float valve is open to flow water into the tank during a flushing operation. The coppertubing has a longitudinal section which extends downwardly and vertically from its connection to the flexible tube, an integrally joined first lateral or horizontal section curved or bent to lie on the bottom wall of the tank adjacent to the rear wall, and an integrally joined second lateral or horizontal section curved or bent to extend substantially normal to the first lateral section and lie on the bottom wall of the tank adjacent to the then facing end wall of the tank. The lateral sections of the coppertubing include small spaced apart apertures opening inwardly toward the center of the tank cavity, through which jets of water are emitted over the bottom wall of the tank as water flows through the flexible tube and copper tubing. The copper tubing terminates at an open free end adjacent the end wall of the tank along which it lies, such open free end facing the opposite side wall of the tank at its intersecting corner region where it meets the adjacent end wall. When water flow through the flexible tube and coppertubing it is spewed out in a stream directed toward the opposite side wall at the corner intersection. The impact of the water against the opposite side wall in that corner region forces the water to turn and begin to swirl in a circular whirlpool current or stream on the bottom wall of the tank. Such whirlpool current or stream, combined with the jets of water being emitted across the bottom wall of the tank from the small apertures of the lateral sections of the coppertubing, agitate the sediment accumulated at the bottom of the tank, raising the sediment into the whirling stream of water, and carrying the sediment with such whirling stream of water toward the centrally located drain in the bottom of the tank which is open during the flushing operation to carry water to the toilet bowl. Thus, during each flushing operation, sediment in the toilet tank is automatically flushed out of the tank into and through the toilet bowl, and on out the drain conduit leading ultimately to the sewer tile.

Abstract: A method for controlling any increase in Mooney viscosity during aging of siloxane-functionalized polymers in-cludes the step of adding a viscosity stabilizing effective amount of a viscosity stabilizing agent selected from the group consisting of alkyl alkoxysilanes of the structural formula R1n Si(OR2)4-n wherein R1 is selected from the group consisting of C1 to C20 alkyl, C4 to C10 cycloalkyl, or C5 to C20 aromatic groups, wherein R2 may be the same as or different from R1 and is selected from the group consisting of C1 to C20 alkyl, C4 to C10 cycloalkyl, or C5 to C20 aromatic groups, and wherein n is an integer from 1 to 3. The method provides for the stabilization of Mooney viscosity of siloxane-functionalized polymers at any given level upon aging. The viscosity stabilizing agents react with the siloxane-functionalized polymers during hydrolysis of the siloxane end groups to form moisture stabilized polymers.

Abstract: A method of growing robust large area colloidal photonic crystals and devices produced thereby. A suspension of monosized colloidal spheres (1) is subjected to a composite shear (6) by applying a sequential set of shearing forces. The crystalline layers within the colloid experience shearing forces with components in both x and y directions, forcing the colloid into a single face-centred-cubic structure in preference to a twinned face-centred-cubic structure. The method may also comprise the use of a dispersion medium which is capable of undergoing a controllable phase change from a liquid phase to a solid phase. The crystal may be fixed into a single face-centred cubic structure.
