Patent CA-2103338-A1 (CA)
Inventor: DANYLUK PAUL R
IPC: F02M61/06
Filed: 1993-11-17
Abstract: A fuel injection system for an internal combustion engine, such as a dual fuel diesel/gas engine of the type requiring an overall system turn-down ratio capability, from maximum fuel flow rate to minimum flow rate, on the order of 100 to 1, employs a conventional variable displacement primary pump having a turn-down ratio substantially less than the overall system ratio. The output of the primary pump branches to supply two parallel fuel conduit paths.   Each path includes a pressure actuated shut-off valve means. The primary shut off valve means path opens to permit flow through the path to the engine at pressures in excess of a relatively high value.   The secondary valve means opens to permit flow through the secondary path in response to a relatively lower pressure at the pump outlet.   And, a fixed quantity fluid dispenser in the secondary flow path operates in response to opening of the secondary valve means, to displace a fixed quantity of fuel through the secondary path and into the engine.    In general, the secondary path prevents the build-up of sufficient fuel pressure at the output of the primary pump to open the primary valve means when the variable output rate of the primary pump is set at the lowest part of its range. When the output of the primary pump is set sufficiently high, pressure builds in the outlet line of the primary pump because the delivery rate of the primary pump exceeds the rate at which fluid can be disposed of in the secondary path; the additional fuel displaced by the main pump is delivered to the engine accordingly, through the primary path.

Title: Process for the production of alkali metal hydroxides and elemental sulfur from sulfur-containing alkali metal salts
Inventor: ZOPPI GIANNI
IPC: C01B17/26
Filed: 1993-08-25
Abstract: Abstract The  present invention relates to a process  for the  production  of alkali metal hydroxides,  such  as caustic soda,         and elemental sulfur, characterized in that to an electrochemical cell an aqueous solution of an alkali metal sulfide,  e.g.,  sodium sulfide, is fed in order to cause the following reactions to  take place:          * at the anode Na2S ---> 2Na+ + S + 2e-* at the cathode 2H2O + 2e- ---> 2OH- + H2 with the overall reaction being thus the following:          Na2S + 2H2O ---> 2NaOH + S + H2.    Elemental   sulfur,   which  is   insoluble,   is recovered from the anodic solution by filtration.  The NaOH   solution   is  extracted  from  the   cathodic compartment by means of the addition of water.     The concentration of the solution of alkali metal hydroxide    obtained    is   a   function   of    the characteristics of the membrane used.      In the disclosed process,  the standard potential of the anodic reaction:                    S2- - 2e =.S0 is  lower  than of the corresponding  processes  which lead to the development of gases (Cl2, O2), thereby an adavantageous  decrease  in cell  voltage  being  made possible.

Abstract: A liner for use in flexible bulk containers includes a tubular body section with at least one continuous baffle strip extending around the interior circumference of the body section, with the baffle strip attached to the body section at spaced apart intervals to form baffles defining four triangular shaped corners in the body section.  The liner is formed on an apparatus having a feed path with feed rollers for feeding lengths of the liner material and the baffle strip material into contact with one another.          The  feed roller controlling the liner material has a variable speed control to allow longer lengths of the liner material to be placed adjacent the baffle strip.   Heat sealers mounted along the feed path seal the lengths of baffle ribbon to the lengths of liner material at spaced apart intervals such that the longer lengths of the liner material  form  pockets  between  the  ribbon  and  liner material.  A cutter mounted adjacent the feed path cuts a length of the liner material, and a folding arm folds the cut length in half. The cut ends of the length of liner material are sealed with a band heat sealer mounted at the end of the feed path to form a tubular liner wherein the baffle strip defines triangular shaped corners in the liner.
Patent CA-2116712-A1 (CA)
Inventor: PIKUS ILYA
IPC: C08G63/80
Filed: 1994-03-01
Abstract: ABSTRACT OF THE DISCLOSURE         A system for crystallization of polymers involving the use of a stationary housing with a rotor mounted for rotation within the housing.  The rotor supports a plurality of spaced apart hollow discs and heated fluid is delivered to the interior of the discs.  The polymer material to be treated is fed into the housing for heat exchange contact with the exterior surfaces of the discs.  The rotation of the discs in addition serves as the propelling force for the material along the length of the housing at which point the material is discharged.  The speed of rotation of the rotor is controlled to influence agitation and conveying of material in the housing to thereby control the crystallization reaction.  A holdup mechanism which operates independently of the speed control is located adjacent the discharge location to contribute to the fixing of the residence time.  The material inlet operation, discharge operation and residence control are such that the ratio of crystallized to uncrystallized material is maintained within desired limits, typically at about 4 to 1.  The method and apparatus provides various other operating parameters and structural features which maximize the efficiency of the crystallization reaction.

Title: Adiabatic dynamic logic
Inventor: DICKINSON ALEXANDER G
IPC: H03K19/00
Filed: 1994-03-04
Abstract: ADIABATIC DYNAMIC LOGIC            Abstract A novel family of adiabatic dynamic logic gates can have power*delay products at least an order of magnitude or more below that which was possible in previous families of logic gates.  No complex circuitry or unusually configured devices are needed to implement this logic family.  In particular, this logic family requires fewer devices and less area per logic gate as compared with ordinary CMOS logic circuitry.  This is unlike previous reversible logic proposals which required large numbers of transistors per gate.  This logic circuitry can operate from very low supply voltages and need not be optimized for a particular voltage.  This logic does not suffer from crowbar currents usually found in prior circuitry such as CMOS logic.  Logic levels are regenerated at nearly every stage unlike some previous schemes which reduce energy dissipation only by sacrificing logic levels.  At each stage in a calculation, this logic recovers a substantial amount of the energy used to perform the calculation and returns it to the power supply.
