Inventor: OKAMOTO MASAKATSU
IPC: F28F27/00
Filed: 1992-04-07
Abstract: A heat treating device for use in chemical and food industries, including a heat exchanger of jacket type, for example, which surrounds a reaction vessel, wherein heat media such as steam and water are fed to the heat exchanger and also sucked by sucking means such as an ejector to put the interior of the heat exchanger in a reduced pressure state, whereby effecting heat treatment at relatively low temperature below 100°C, for example, the improvement of which is to prevent variation of the reduced pressure level in the heat exchanger for keeping stability of treating temperature.  The improvement is attained by connecting another sucking means to the upper portion of the heat exchanger to suck vapor in the upper portion of the heat exchanger aside from the first-mentioned ejector which is connec-ted to the lower portion of the heat exchanger.

Title: Process for bleaching of lignocellulose-containing material
Inventor: ANDERSSON LENNART
IPC: D21C9/10
Filed: 1992-04-27
Abstract: The present  invention relates to a process for delig-nification and  bleaching of  chemically digested lignocel-lulose-containing pulp,  where the  pulp is  treated with a complexing agent at a pH between 3.1 and 9.0, whereupon the pulp is  bleached with  ozone. The initial treatment with a complexing agent removes the ions of  certain metals detri-mental to  the subsequent  ozone bleaching, while retaining in the pulp the desirable ions, primarily of alkaline earth metals. Thereby,  the selectivity in the delignification is increased and the strength of the pulp maintained. The pulp can be  bleached with peroxide before the ozone step and/or after the treatment according  to the  invention, to obtain the desired final brightness and completely avoid formation and discharge of chlorinated organic compounds.

Patent CA-2070296-A1 (CA)
Inventor: VAN DER PLAS GERT
IPC: H04B10/272
Filed: 1992-06-03
Abstract: To determine the equalisation delay of a substation (53), the main station (C) of a transmission system measures, during an initial coarse measurement. the time interval between the sending of a first ranging signal to the substation and the receipt of a reply signal.  This reply signal has a frequency and amplitude substantially lower than the information signals sent by other substations (51, 52) of the system to avoid interference therewith.  During a subsequent fine measurement the main station measures the time interval between the sending of a second ranging signal and the receipt of a second reply signal having the same characteristics as the information signals.  The other substations have to stop transmission of signals during an interval equal to the uncertainty time interval with which the equalisation delay was measured during the coarse measurement.  To be, able to apply this method, the receiver at the main station includes means to isolate (AZ) the first reply signal from the information signals and to recognize (COR) them, and a processing unit (PU) to determine the equalisation delay.

Title: Method and apparatus for controlled reaction in a reaction matrix
Inventor: MARTIN RICHARD J
IPC: F24H1/00
Filed: 1992-07-02
Abstract: ABSTRACT OF THE DISCLOSURE Method and apparatus are provided for establishing and controlling the stability and movement of a reaction wave of reacting gases in a matrix of solid heat-resistant matter, wherein such reacting gases may be recuperatively pre-heated. At least a portion of the bed is initially preheated above the autoignition temperature of the mixture whereby the mixture reacts upon being introduced into the matrix thereby initiating a self-sustaining reaction region, after which the pre-heating can be terminated. The stability and movement of the wave within the matrix is maintained by monitoring the temperatures along the flowpath of the gases through the bed and adjusting the flow of the gases and/or vapors or air to maintain and stabilize the wave in the bed. The method and apparatus provide for the reaction or combustion of gases to minimize NOx and undesired products of incomplete combustion. A recuperative heat exchange system may be used to preheat the reactants with heat generated by the reaction by channeling hot exhaust gases through the matrix surrounding reactant inlet tubes. The inlet tubes are thermally conducting and contain an interior matrix. The matrices interior to and surrounding the inlet tubes promote radiative heat transfer.

Patent CA-2075221-A1 (CA)
Title: Electrode
Inventor: CARLSON WILLIAM P
IPC: C23F13/02
Filed: 1992-08-03
Abstract: An electrode is disclosed which is particularly useful as a reference electrode in cathodic protection systems. In any reference electrode or half cell, its continued stability is predominantly dependent on the metal ion concentration around it. In time such ions tend to leach away reducing the stability, effectiveness and life of the electrode. With the present invention such ions in the electrolyte may be replenished by the addition of a concentrated solution of metel salt to a ceramic canister which may include a glaze coating which may have one or more diffusion ports permitting the metal salt solution to leach at a controlled slow rate to the area surrounding the electrode ensuring continued stability and longer effective life for the electrode, The one or more diffusion ports also provide a low resistance current path to or from the lead within to the canister and the surrounding electrolyte.

Title: Bi-fold door locking device
Inventor: HASENHUENDL ERIC
IPC: E05C19/18
Filed: 1992-12-01
Abstract: ABSTRACT     A unique three-sided channel for use for locking a pair of bi-fold doors is the subject matter of the present invention.          The three-sided channel can be of most any configuration as long as the top portion is slightly larger than the thickness of the bi-fold doors.  The channel is installed when the bi-fold doors are in the open position.  The channel is then slidably moved along the top edge such that it rests adjacent the front, back and top of one of the doors.  Once the doors are placed in the closed position, the channel is moved across the top edge of the other door so that the front, rear and top portions of the channel are adjacent to the front, rear and top edge, respectively, of both of the doors.  To move the doors from the locked to the unlocked position, the channel is slidably moved onto one or other of the doors so that they are free to open.
