Abstract: In the case of a heated nozzle, to be precise in the case of a so-called long nozzle (10) for feeding a polymer melt into the mould cavity of a plastics injection mould, there is provided a nozzle body (18A, 18B, 18C), which receives a tubular heater (29) in grooves of different pitch regions. The nozzle body (18A, 18B, 18C) is divided, at least in the transitional region from one pitch region to the other pitch region (A, C), forming separate axial sections which are pushed-on with a close fit on an inner supporting tube (19). If appropriate, the housing surrounding the nozzle body (18A, 18B, 18C) is also divided. The novel long nozzle (10) allows fabrication to be made significantly easier and, in addition, the overall length to be adapted to the individual requirements of the mould maker. <IMAGE>

Abstract: This invention provides a method for on-line prediction of polymer properties. In a continuous polymerization reactor in which an irreversible polymerization reaction occurs, sensors provide axial temperature and pressure profile in the reactor as well as monomer flow rates and concentration for determining Mw, Mn and polydispersity (Mw/Mn). Based on a non-Newtonian fluid mechanics analysis, differential influx analysis of a side stream incorporation and determination of the moments of the molecular weight distribution via a Newton-Raphson algorithm, the model calculates an axial polymer properties profile.

IPC: G06F1/20

Abstract: A real-time power conservation apparatus and method for portable computers employs a monitor (40) to determine whether a CPU may rest based upon a real-time sampling of the CPU activity level and to activate a hardware selector to carry out the monitor's determination. If the monitor determines the CPU may rest, the hardware selector reduces CPU clock time (260, 270, 280); if the CPU is to be active, the hardware selector returns the CPU to its previous high speed clock level. Switching back into full operation from its rest state occurs without a user having to request it and without any delay in the operation of the computer while waiting for the computer to return to a "ready" state. Furthermore, the monitor adjusts the performance level of the computer to manage power conservation in response to the real-time sampling of CPU activity. Such adjustments are accomplished within the CPU cycles and do not affect the user's perception of performance and do not affect any system application software executing on the computer.

Abstract: A low cost process for fabricating solder column intercon­nections for an electronic package is described. The process includes the steps of filling an array of pin holes in a pin mold (14) with a lead/tin solder, which array of pin holes is in substantial registration with the array of conductive pads (12) on one side of a chip carri­er (2); heating the lead/tin solder in the pin mold such that the solder becomes molten and coalesces with the array of conductive pads of the chip carrier, thereby forming an array of miniature pins (4) bonded to the array of conductive pads of the chip carrier; joining circuit components to the other side of the chip carrier; and reflowing an eutectic lead/tin solder paste screened to the corresponding array of conductive pads of a circuit board to bond the free ends of the array of miniature pins of the carrier to the corresponding array of conductive pads, thereby forming the solder column connections be­tween the chip carrier and the circuit board. The process is suitable for mass production of reliable, high-density electrical inter-connections between a chip carrier and a supporting circuit board.

Abstract: Two or more signal paths are provided for receiving a radio frequency signal. One or more signal paths include conventional bandpass filters for eliminating interference and noise signals. One or more remaining signal paths include reduced filtering devices for increasing the sensitivity of a radio frequency receiver to the desired signal. Each of the receiving paths is coupled to a respective radio frequency amplifier. Provided that each radio frequency amplifier has equivalent current-source output impedances, the output signals from each amplifier are added constructively if they are in-phase. If the output signals are out-of-phase, a phase inverter inverts the phase of one signal so that the signals may be added constructively. The combined signals of the two or more radio frequency amplifiers pass through various signal processing components associated with conventional superheterodyne receivers. A control unit produces gain variation signals for controlling the gain of each radio frequency amplifier. Accordingly, the control unit controls whether the desired signal is received from a first signal path, a second signal path, or as a weighted combination of two or more signal paths.
