Granted: 1992-02-11
Abstract: ABSTRACT OF THE DISCLOSURE A long  retracting sootblower  for boiler  cleaning of  the  type having a  lance tube  which is  advanced into  and out  of a  boiler  and simultaneously rotated, and having one or more nozzles discharging a  jet of blowing medium which  trace helical paths.   An indexing mechanism  is provided to change  the positioning of  the helical paths  traced by  the nozzles between successive  actuation cycles to  minimize boiler  erosion and mechanical stress  caused by repeated  blowing medium impact  against surfaces within the boiler.   The indexing mechanism includes  relatively slidable longitudinal advancement rack sections which cause the  engaging pinion gears to index by one or more teeth upon each actuation cycle.   A movable rack portion  is biased  by a compliant  element to  remain in  a normal position until  initial advancement  of the  lance carriage  which causes the  movable portion  to  be indexed  with  respect to  the  fixed portion of the  rack.  The  movable rack portion returns  to its  normal position during other  periods of the  actuation cycle thereby  providing said indexing.

Granted: 1992-11-17
Abstract: ABSTRACT         A package for integrated circuit chips, or other elec-trical devices, provides mechanical shock and thermal protection for the chips, and in addition, protects the chips from electro-magnetic interference and electrostatic discharge.  The package includes a printed wiring board base for reception of one or more circuit chips, and a conductive heat sink and cover.  The conduc-tive heat sink, in conjunction with a reference plane in the wir-ing board base, acts as an EMI shield for the chips.  The heat sink is covered with an insulating layer, on top of which, a con-ductive coaling is placed.  The conductive coaling is electrically connected to the reference plane, and the two act to protect the chips from electrostatic discharges.  Compliant pads support the chips, and a thermally conductive elastomer can he placed on top of each chip between the chips and the inner top surface of the heat sink.  The chips are thereby held securely in position, and are thermally connected to the heat sink.

Abstract: RADIOLUCENT BREAST IMPLANT          Abstract of the Disclosure A radiolucent breast implant is comprised of a silicone envelope filled with any biocompatible triglyceride such as peanut oil or sunflower seed oil, or any other material having an effective atomic num-ber of 5.9 which is the effective atomic number of fat, the major component of a human breast.  Such a breast implant is radiolucent in that it duplicates the photoelectric interaction of fat which is the major effect producing subject contrast at low radia-tion levels as used in mammography.  A radiolucent breast implant dramatically improves the usefullness of mammography in detecting tumors in patients having breast implants and may also result in a lower radia-tion dose for each examination.

Abstract: The present invention relates to a method and apparatus for determining the electrical conductivity of the ground, particularly in connection with aerial prospecting, with the use of a transmitter unit (S) and a receiver unit (M) located at a distance from said transmitter unit and particularly carried by an aircraft (21). The transmitter is arranged to generate an electromagnetic field which induces an electric current in the ground, and the receiver is arranged to measure magnetic and electric fields induced by said current at the measuring site, said fields representing a measurement of said electrical conductivity and variations therein. The magnet field from the transmitter is transmitted horizontally as is directed transversally of an imaginary line that connects the transmitter (S) with the receiver (M). The electric field E from the transmitter is measured in the receiver in a radial direction to the transmitter. The magnetic field H is measured in a direction parallel with the magnetic transmitter-field. Of the measured magnitudes E and H the ratio E/H and/or the phase difference (p are formed, both of which are dependent on the electrical conductivity of the ground.

Abstract: Chemimechanical pulp is produced from lignocellulosic material in a process in which the material is impregnated in two stages. The material is treated in the first stage with alkaline and, subsequent to passing an intermediate draining and reaction step, in the second stage with a solution that contains peroxide. The quantities of alkali and peroxide charged are fully optional and are independent of one another. The material is then optionally subjected to a further drainage and reaction step, and thereafter pre-heated at a temperature of between 50°C and 100°C, whereafter the material is refined in one or two stages.The optimal brightness of the processed pulp for a given peroxide consumption is achieved by a balanced division of the peroxide charge between chip impregnation and bleaching.
