Abstract: The present invention relates to a novel method for forming metal matrix composite bodies. A permeable mass of filler material (1) is spontaneously infiltrated by a molten matrix metal (3). Particularly, an infiltration enhancer and/or an infiltration enhancer precursor and/or an infiltrating atmosphere are in communication with the filler material (1) at least at some point during the process, which permits molten matrix metal (3) to spontaneously infiltrate the filler material (1). After infiltration has been completed to a desired extent, additional matrix metal is added to that matrix metal (3) which has spontaneously infiltrated the filler material (1) to result in a suspension of filler material (1) and matrix metal (3), said suspension having a lower volume fraction of filler relative to matrix metal. The matrix metal (3) then can be permitted to cool in situ or the mixture of matrix metal and filler material can be poured into a second container as a casting process to form a desired shape which corresponds to the second container. However, the formed suspension, whether cast immediately after being formed or cooling and thereafter heating and casting, can be pour cast into a desired shape.

Abstract: A process for automatically going into the mode for increased suction extraction of the gases emitted by the tanks of series for the production of aluminium by igneous electrolysis using the Hall-Heroult process, each tank being closed around its periphery by a plurality of removable covers which are disposed in substantially sealed relationship with each other and between each thereof and their support means on the periphery of the tank, the gases being collected over each tank by at least one duct connected to a centralized suction extraction system. The temperature of the gases in the duct is continuously measured. Opening of at least one cover gives rise to an abrupt drop in temperature, which makes it possible to put the system into the increased suction extraction mode, which will be automatically stopped when, all the covers being closed again, the temperature of the gases will substantially resume its initial value. The power required for the suction system is thus substantially reduced.

Date Jul. 3, 1986.A method of measuring the volume (V) of a gas in a container (20) comprises varying the container volume according to a sine wave between a minimum and a maximum value, the variation being made at a constant frequency but at varying amplitude, to obtain a predetermined pressure difference ( DELTA p), and the volume difference ( DELTA V) corresponding to said predetermined pressure difference ( DELTA p) being determined by detecting the points of time when at least two points on the sine wave are attained which correspond to two predetermined values of the container volume. By measuring the time between the two points on the sine wave, the sine wave peak values for the volume difference ( DELTA V) corresponding to said predetermined pressure difference ( DELTA p) may be calculated and, thus, the said volume difference ( DELTA V). By means of the formula V= DELTA Vxp0x eta / DELTA p, wherein p0=the static pressure and  eta =Cp/Cv wherein Cp an Cv are the specific heat capacity at, respectively, constant pressure and constant volume for the gas within the container, the gas volume (V) in the container may then be determined. An apparatus for carrying the method into effect has also been constructed.

Title: Method and system for mounting building wall panels to building frames, incorporating mounting means elements with two degrees of freedom
Inventor: SEMAAN EZZAT S

Filed: 1990-03-05
Granted: 1994-12-13
Abstract: A system for mounting building wall panels to building frames, and a method of its use, are disclosed.   The system is comprised of one or more insertional frame(s), at least one of which provides a mounting means element therein with two degrees of motion freedom, which insertional frame(s) are secured to a building wall panel.  The system provides for quick, easy and economical mounting of building wall panels to building frames by construction personnel as the mounting means element(s) in the insertional frame(s) can be adjusted to match the location of the corresponding mounting means on a building frame.  The invention also, most importantly, provides protection against the development of potentially damaging stresses in building wall panels mounted to a building frame as a result of seismic activity, thermal expansion, wind induced building shape changes etc.   Protection against potentially damaging stresses results from the fact that the two degrees of motion freedom alluded to remain after a building wall panel is mounted to a building frame by means of the present system.

Abstract: The invention describes a novel process for the preparation of polycarbonate and/or polyarylate block copolymers with poly(aryl ethers). The process is comprised of steps: (a) the reaction of a dihydroxy-terminated poly(aryl ether) oligomer with a high molecular weight polycarbonate, or a high molecular weight polyarylate, or a high molecular weight poly(arylate-carbonate) to yield a block copolymer; followed by (b) the coupling of the material obtained in step (a) to the required molecular weight, us-ing a diaryl ester of carbonic acid or of a dicarboxylic acid. Both steps are performed in the presence of a catalyst. The copolym-erizations can be run in bulk under vacuum in a single or twin screw extruder. Using the above conditions high molecular weight, high quality block copolymers having a combination of excellent properties are obtained in a matter of minutes.

Abstract: ABSTRACT OF THE DISCLOSURE   A vehicle brake warning device for use in a  vehicle with  a  brake pedal includes  an  inertial  transducer which produces different electrical signals in response to  the magnitude of inertial force experienced  during braking,  a  control  circuitry  receiving   electrical signals  from  the inertial transducer  and  having  an output  dependent  upon  the  received  signal,  and  a warning  device activated by the output of the  control circuitry.  Whenever  the brake pedal  is  actuated  to reduce the  speed  of  the  vehicle,   the   inertial transducer   experiences   an  inertial   force   whose magnitude  depends upon the speed of the  vehicle.  The inertial transducer sends out an appropriate signal  to the control circuitry, which signal corresponds to  and is dependent upon the magnitude of the inertial force. The  control circuitry activates the warning device  to send  out a warning signal which varies depending  upon the magnitude of the inertial force.
