Granted: 1991-07-30
Abstract: ABSTRACT         An automotive charging apparatus employs a high voltage load such as a deicing means for deicing a windshield of the auto-mobile in the line which connects a battery with an alternator.          The automotive charging apparatus also employs a switch in parallel with the high voltage load so that an output voltage is supplied both to the high voltage load and to the battery when the switch member is opened and the output voltage is supplied only to the battery when the switch member is closed.  The output voltage of the alternator changes to the higher level when the switch member is opened in order to maintain the battery voltage within the range of the predetermined value.

Abstract: ABSTRACT OF THE DISCLOSURE      Process for gas phase polymerisation of olefins using a highly active catalyst in a fluidized bed reactor (1), comprising a reactor body (2) partially occupied by the fluidized bed and surmounted by a disengagement chamber (3).  The gas mixture  withdrawn from the disengagement chamber (3) is fed to a  dust separator (6) e.g. a cyclone, to separate the fine particles entrained by the gas.  The gas is cooled, compressed and recycled to the base of the reactor. The particles are withdrawn from the dust separator (6) by a mixing device (8) which mixes the particles with a carrier gas.  The carrier gas and particles are recycled to the reactor where they are introduced into the reactor body (2) through an opening in the side wall thereof at a  position above the fluidized bed, but below the disengagement chamber (3).  The velocity of the particles introduced into the reactor is insufficient to cause them to be blown directly into the bed.

Patent CA-1327715-C (CA)
Inventor: DAVLOOR RAMANA
IPC: G01N1/16
Filed: 1989-04-04
Granted: 1994-03-15
Abstract: ABSTRACT OF THE DISCLOSURE    A liquid sampling device is disclosed which is particularly suitable for sampling chemical wastes or hazardous chemicals. The device has a low resistance to flow so that composite samples can be obtained from a single draw. A representative sample can be obtained of a liquid in a container throughout its depth, as opposed to taking several samples at various depths. The possibility of cross-contamination, when taking samples from several containers, is reduced as a result of fewer internal components and simplified replacement of contaminated parts. The overall structure, particularly that of the container for receiving and holding the sample, is simplified to make its production cost low enough for a disposable arrangement.
Patent CA-1296093-C (CA)
Inventor: ETIENNE JEAN-DANIEL
IPC: G01S15/18
Filed: 1989-04-13
Granted: 1992-02-18
Abstract: ABSTRACT     An echo tracker clamps a time window for detecting an echo at the position of an echo produced by a mobile wall receiving an ultrasonic pulse signal at a repetition rate Fr. It includes a depth counter (28) which counts in order to define the beginning of the time window in relation to a pulse of the pulse signal and which when it reaches a given value, supplies an enabling signal to activate authorization means (30) and a position detector (32).     Enabling means (30) provide an enabling signal for a given time which defines the detecting time window. During this time, the position detector counts until the echo is detected. The value reached at that instant is used to clamp again the time window and to modify the initial value of the depth indicator.   The invention is useful in the medical field for measuring the changes of the position of an interface between two tissues.

Title: Method of protein analysis
Inventor: HUANG ERIC
IPC: G01N33/68
Filed: 1989-09-29
Granted: 2000-04-18
Abstract: A method of analyzing a protein, namely determining the amino acid sequence of a protein is described. Trypsin is added to a protein to form a liquid phase mixture of trypsin and the protein. The disulfide linkages of the protein may be reduced and the resulting sulfhydryl groups alkylated either before or after the addition of trypsin. The trypsin is allowed to digest the protein long enough to cleave protein into tryptic fragments. A portion of the digested mixture is ionized by ion evaporation to produce gas phase ions of the tryptic fragments, the gas phase ions being predominantly doubly charged with one charge at each end of the doubly charged ions. The gas phase ions of the tryptic fragments are analyzed by sequentially selecting therefrom ions of a desired mass to charge ratio i.n a first mass analyzer. The selected ions are fragmented by collision in a second mass analyzer to produce daughter ions, and the daughter ions are then analyzed in a third mass analyzer.
