Abstract: METHOD AND APPARATUS FOR CONTINUOUS MIXING OF SMALL, PRECISE QUANTITIES OF BULK MATERIALS WITH A LIQUID STREAM         Abstract A continuous mixer is provided for com-bining bulk materials metered at a relatively slow rate into a liquid stream and is particularly useful for preparing an innoculant solution for treating feed pellets,  seed or the like.   The mixer has a vertical separation tube extending between a screw feeder and a mixing zone in a liquid conduit there-below,  and  the  tube  is  independently  pressurized with air to substantially preclude ascent of liquids within the tube to ensure that all of the mixing occurs within the liquid line and to prevent the liquid from rising to a level sufficient for wetting the innoculants stored within a hopper adjacent the screw feeder. Air pressure within the tube is selectively adjustable in order to vary the spray produced by a nozzle at the end of the fluid conduit from a liquid stream essentially free of air to a finely dispersed fog which includes substantial quantities of air.

Title: Freeze concentration system and method
Inventor: GHODSIZADEH YOUSEF
IPC: A23F5/30
Filed: 1989-02-15
Granted: 1993-09-28
Abstract: ABSTRACT    A continuous, counter-current freeze concentration system and method for concentrating aqueous solutions such as fruit juices, coffee and cold water soluble tea extracts, milk, beer, wine, vinegar, and the like in which the aqueous liquid is passed through one or more concentrating stages, each of which include a crystallizer associated with a gradient column, to crystallize ice in each of the stages and increase the concentration of the liquid, and the ice formed in each stage is passed in reverse direction through the stages.  Ice crystals are separated and removed from the system in a wash column associated with the first stage, and concentrated liquid is removed as product from the last stage.  The environment viscosity of ice crystals formed in each stage is reduced by forming the ice crystal fraction of the slurry produced in the crystallizer of each stage into a porous rising bed of agglomerated ice crystals in the gradient column associated with the crystallizer, and contacting the ice bed with a counter current flow of more dilute liquor whereby liquor occluded on the ice crystals is displaced with more dilute liquor as the ice bed rises in the column.  The degree of compaction and thus the porosity of the ice bed formed in each gradient column is con-trolled.  Ice removed from the porous ice bed is transferred to the more dilute liquor and is supplied to the crystallizer of a preceding concentrating stage or to a wash column.  Liquor sep-arated from the slurry and displaced from ice crystals in the gradient column is introduced into the gradient column of the succeeding stage and recirculated to the crystallizer of that stage.  This reduction in the environment viscosity of ice crystals facilitates the removal of liquor occluded on the ice and promotes the growth of ice crystals in the system.

Abstract: An immunoassay procedure for detection of analytes in urine wherein an immunological reaction is conducted in an aqueous phase containing the urine and a filterable immunocomposite containing an inherently colored gold sol particle is formed if the assay is positive.  The colored, gold sol particle containing immunocomposite is collected for direct visual observation on a filter element. False positive readings are minimized by (1) removing contaminants from the urine to prevent clogging of the filter element and non-specific binding of unreacted reactants thereto by contacting the urine with a porous contact element having a detergent material dispersed on its external and interstitial surfaces; (2) preventing non-specific binding of unreacted immunoreactive substances to the filter element by blocking the latter with polyvinyl pyrrolidone; and/or (3) including a green dye material in the aqueous reaction phase to improve the optical distinction after washing the collection filter between negative and positive results on the filter.

Title: Method and arrangement for channel monitor and control

Abstract: ABSTRACT OF THE DISCLOSURE      A method and means for controlling transmissions among a plurality of communication units is described that determines an inhibit state based upon an inhibit signal and information in a header preceding a coded message before allowing transmission.  This inhibit state prevents all of the other remote units from transmitting while a prescribed remote unit transmits a coded message or an acknowledgment (ACK) so that collisions between messages and ACKs, or between one ACK and another, are avoided.  Message-message collisions are substantially reduced since the method causes a remote unit to utilize a random delay before attempting a retry to send the message a second time.  Hence, the method and arrangement better coordinates inbound transmissions to the base station so that collisions on the inbound channel to the base station are minimized.

Abstract: A variable conductance thermal insulation blanket regulates the temperature of a component (20) on the surface (32) of a spacecraft. The blanket comprises a sealed container (2) and a pressurized gas tank (10). When gas is introduced from the tank (10) into the sealed container (20), heat is conducted away from the component (20) into outer space via conduction through the gas molecules. Thus, component (20) is cooled. When gas is evacuated from within sealed container (2) and there is a vacuum there-within, heat conduction is thwarted, and the primary means of heat escape from component (20) is via radiation. However, radiation is also thwarted by means of a set of stacked radiation sheilds (24) having low emissivity but high thermal conductivity.

Title: Trellis shaping for modulation systems

IPC: H04L27/34

Granted: 1999-06-15
Abstract: In a so-called trellis shaping modulation system, instead of mapping a digital data sequence into a sequence of signal points drawn from a finite-dimensional signal point constellation as in typical coded modulation, the data sequence is mapped into a sequence of signal points drawn from a so-called trellis constellation of available infinite-dimensional sequences so that there is no single N-dimensional constellation used repeatedly in each N N-dimensions.  The region occupied by the available sequences in sequence space is shaped to minimize the required power; i.e., preferably the region is an approximation to the Voronoi region of the trellis code (where the trellis code is not just a repeated lattice code).

Abstract: A facsimile apparatus of the type which is connected to a digital line and which has the function of automatically informing a particular destination terminal of the reception of a facsimile signal from a distant terminal.  In the apparatus, identification information on a particular facsimile apparatus and a telephone number of a destination terminal are previously stored in a memory unit.  During the reception of a facsimile signal, the apparatus detects an identification information of a distant terminal which is transmitted therefrom over a digital line.  If it is determined that the detected identification information corresponds to the identification information stored in the memory unit, the facsimile apparatus automatically originates a call on the basis of the telephone number of the destination terminal which is stored in the memory unit and sends to the destination terminal a message stating that a facsimile signal has been received from the particular facsimile apparatus.  In another form of facsimile apparatus, a telephone number of a destination terminal is previously stored in the memory unit.  This form of facsimile apparatus is arranged to automatically originates, if a facsimile signal is received over a first channel of the digital line, a call on the basis of the telephone number stored in the memory unit and sends a message stating that a facsimile signal has been received to the destination terminal over a second channel of the digital line.
