Abstract: An automotive framing system for positioning a lower body component and at least two upper body components together at precise positions relative to each other prior to fixedly securing the body components together. The framing system includes a conveyor for sequentially moving body preassemblies to a predetermined assembly station. A frame of integral construction is positioned around the body at the assembly station. A lifter at the assembly station lifts the lower body component and upper body components from the conveyor together with the frame to a predetermined elevated position in which the lower body component abuts against the upper body components. With the body preassembly positioned within the assembly station, clamps on the frame engage predetermined location points on the upper and lower body components to hold the upper and lower body components together at preset positions relative to each other whereupon the body components are fixedly secured together. In the preferred embodiment, at least two frames are selectively movable in a direction both parallel and transverse to the conveyor into the assembly station to accommodate different styles of automotive body preassemblies.

Abstract: A core section (10a) is formed in an optical fiber (10) made of a glass material and, electrodes (14a and 14b) are inserted into the clad section (10b) of the fiber (10). When the core section (10a) is irradiated with ultraviolet rays in prescribed intensity patterns while a high voltage is applied to the electrodes (14a and 14b), a grating section (16) in which non linear areas (16a) and normal areas (16b) are alternately formed is formed in the section (10a). The characteristics of the grating section (16) can be changed by utilizing an electrooptic effect by impressing a prescribed electric field upon the section (16) through the electrodes (14a and 14b). A grating element constituted in such a way can be utilized as an optical functional element, such as the wavelength switch, because the Bragg wavelength of the element changes when a voltage is applied.

Granted: 2007-06-05
Abstract: A contaminant detector including a light source for emitting light of a wavelength with peak emission corresponding to that of "blue" light or to that of light of even lower wavelength. Light is emitted through an arrangement containing a liquid sample having a given contaminant, and a sensing arrangement on the other side of the liquid sample detects the amount of light passing through the liquid sample. The measured light is converted into a value indicative of the relative presence of the given contaminant in the liquid sample. It is contemplated that other types of light can be used, particularly if the color of the light is matched, or even approximately matched, with that portion of the liquid sample that is not to be measured (i.e. the "background" or "non-contaminant" portion of the liquid).

Abstract: A method and apparatus are provided for assigning radio network control in a mobile communications system (10) that offers two or more types of bearer services (14, 16). The mobile network (12) broadcasts an initial control message that orders certain mobile terminals (20) to suspend use of their normal terminal-based radio network control decisions and to accept radio network control orders from the land mobile network (12). A subsequent control message can order the resumed use of normal terminal-based radio network control decisions. Consequently, the mobile network (12) can use virtually the same control logic for all of the mobile terminals (18, 20) that it serves, regardless of the type bearer service (14, 16) being carried, As a result, radio signal interference between mobile terminals (18, 20) carrying the different bearer services (14, 16) can be minimized.

Abstract: A method and apparatus achieve a more sustainable lift of a wet or heavy pulp web from a pulp machine to the topmost drying level of a pulp drying, allowing the speed of production to be increased and runnability problems to be minimized. The pulp web is lifted from the last press of the pulp machine to the topmost of the drying levels of the pulp dryer by supporting the web on a support wire. The pulp may be passed through the topmost drying level, and one or two other levels, also supported by a support wire, but in subsequent levels the pulp web is preferably supported only by an air cushion. In each level drying gas is blown toward the pulp web (preferably from both above and below the web) to effect drying, and the web passes around turning rolls between each drying level to enter the next, lower, drying level. The support wire may be of metal or plastic, and has a texture significantly coarser than the texture of wires commonly used in pulp machines.

Abstract: A system is disclosed for carrying packetised voice and other delay-intolerant traffic, for example a voice call for transmission over the "Internet" over a circuit-switched connection when such a connection is available. Incoming packets from a packet data network (52) are identified by a gateway node (60) as having voice characteristics and diverted to travel over a bridge (61) to a circuit-switched network (28, 24, 23) to a terminal (21), instead of a packet network (50). This reduces the load on the packet network (50), which is less suited to voice-type calls than is the circuit-switched network. In the reverse direction, suitable packets generated by the terminal (21) may be routed to the gateway node (60) by way of the circuit-switched network (24, 28) under the control of the terminal (21) itself, or under the control of the network's interface (23) with the terminal, either under the control of the gateway node (60) or autonomously.
