    摘要: Mold for the continuous casting of preliminary sections, in particular double T-shaped preliminary sections, such as beam blank sections or similar sections, wherein all the interior walls of the mold in a mold passage have a tapered course running linearly from top to bottom, this tapered course being dimensioned depending on the degree of shrinkage of the cast strand and produced by machining the interior walls. In this manner, it is possible to optimally adjust the diameter of the mold to the shrinkage process of the cast strand in the region of the mold passage, even for large-sized sections.

    摘要: A radio frequency (RF) switch using a field effect transistor has 2nd order intermodulation distortion improved through use of a feed forward capacitor electrically connected between the gate and a voltage coupler connected between the source and drain of the FET. With a control voltage provided at the gate through a gate feed resistor for operation of the FET, the feed forward capacitor feeds an RF voltage from the drain terminal and the source terminal to the gate terminal through the gate feed resistor.

    摘要: A drum assembly for use with a coupling arrangement includes an outer member and an inner member that is mountable on the outer member. The outer member includes first and second annular portions connected together. The first annular portion has a first mating surface that defines a first opening having a first diameter, and the second annular portion defining a second opening having a second diameter that is smaller than the first diameter. The inner member includes a generally radially extending portion and a flange portion extending generally axially from the radially extending portion. The radially extending portion includes a second mating surface that is engageable with the first mating surface to interlock the inner and outer members together. When the inner member is mounted on the outer member, the radially extending portion extends into the first opening, and the flange portion extends into the second opening.

    摘要: A wireless ad hoc pico network is formed by eyewear and other devices such as a computer, a bracelet and a telephone having similar transceivers mounted on them. Master slave relationships are configurable. Other devices, such as a radio, a CD player, a hand held global positioning satellite system and a heart rate monitor, having similar transceivers, can also be connected with the transceiver of the eyewear. The transceivers operate on globally available, unlicensed radio band, 2.45 gigahertz (GHz) and conforms to the Bluetooth standard. The power consumption of Bluetooth enabled devices is less than three percent of the power consumption of a mobile phone. The eyewear includes a frame and connected to the frame are two temples. Temples are connected to frame via hinges. Temples have a male portion of a connector incorporated in them. Female portion of the connector is made integral with the hinges. When the male portion is inserted in the female portion the temple is attached to the frame. The temples can be removed by pulling the connector apart, and a temple with different apparatus within it can be inserted in place of the removed temples. The temple may have co-molded within its body, an apparatus such as an audio device, a camera, a speaker, and a microphone, and a display device such as liquid crystal or an alarm. In another embodiment, eyewear constitutes a distance alarm to monitor the movement of, for example, a child. A device in form of, for example, a bracelet is worn by the child. The transceivers in the eyewear and the bracelet form a small-range wireless network, i.e., piconet, wherein the eyewear and the bracelet communicate using signals conforming to the Bluetooth technology. The transceiver in the eyewear is configured to generate an alarm when the bracelet exceeds a predetermined distance from eyewear.

    摘要: A snow sled (100) comprising a seating portion (116) that includes a lightweight space frame (104) having a suspension-type seat (108) stretched among the space frame. The sled further includes a steering portion (120) and an articulated steering mechanism (112) that links the steering portion to the seating portion. The articulated steering mechanism allows the steering portion to be pivoted laterally relative to the seating portion so as to make the sled readily steerable. A pair of rear skis (164, 168) are removably attachable to the seating portion. The steering portion (120) includes a ski support (200) and a pair of front skis (204) pivotably attached to the ski support. Chatter and movement of the front skis are dampened by a pair of boots (228) that engage the ski support and the respective front skis.
