Patent CA-1325981-C (CA)

Abstract: ABSTRACT The present invention is a process for purifying polydextrose to remove manufacturing contaminants such as glucose, sorbitol, citric acid, oligomers, 1,6-anhydro-glucose, 5-hydroxymethylfurfural and other low molecular weight constituents by reverse osmosis wherein an aqueous solution of polydextrose is filtered by pressing it tangentially over a porous membrane at high pressure. This inventive process produces a purified polydextrose with the 1,6-anhydroglucose content therein reduced to less than about 0.2% (W/W) and a reduction in the 5-hydroxymethylfurfural content to below detectable levels or less than about 0.01% (W/W), thereby virtually eliminating any bitter taste or musty off-flavor.

Title: Low pressure hydrocyclone separator
Inventor: FLANIGAN DAVID A
IPC: B04C11/00
Filed: 1989-06-23
Granted: 1994-06-07
Abstract: Abstract Of The Disclosure A system is provided for the separation of oil from oily water, particularly where the oily water is available only at relatively low pressures insufficient to drive a hydro-cyclone separator.   Particular  combinations  of  pumps and hydrocyclones  can  be  effective  in  these  low  pressure situations where the pressure boost required is not substan-tially greater than a differential pressure at which the pump  begins  to substantially degrade  the  volumetric mean size  of  droplets  of  oil  in  the  oily  water  passing therethrough.   This  is achieved by operating the pump at relatively near its maximum flow rate capacity to substan-tially reduce on  a percentage  basis  the effect of  fluid slippage within the pump.  Improved techniques for analysis of oil droplet size distribution are also disclosed.

Abstract: Process for working up dusts which are produced in the electrothermal production of phosphorus Abstract of the disclosure A process is provided for working up dusts which have been precipitated electrostatically from the gas mixture composed essentially of carbon monoxide and phosphorus vapor produced in the electrothermal production of yellow phosphorus, which process comprises converting the dusts into a calcinate at 300 to 800°C under oxidizing condi-tions  in a first  step,  leaching the calcinate with phosphoric acid in a second step, adjusting the pH of the solution in phosphoric acid to 0 to 1.5 with sodium hydroxide solution in a third step, precipitating the sulfides of lead, copper and cadmium from the partially neutralized solution in phosphoric acid by adding sulfide and filtering them off in a fourth step, adjusting the pH of the filtered, partially neutralized solution in phos-phoric acid to about 1.5 to 5.0 with sodium hydroxide solution and precipitating zinc sulfide, if necessary by adding further quantities of sulfide, and filtering it off in a fifth step,  further neutralizing the sodium phosphate solution, if necessary after expelling excess sulfide, with sodium hydroxide solution and separating it from precipitated calcium compounds in a sixth step, and using the resultant sodium phosphate solution in this form in a known manner to produce sodium phosphate salts.

Abstract: ROTARY HOE TOOL Abstract of the Disclosure A  rotary  hoe  tool of the type wherein one or more of such  rotary  hoe  tools  are mounted for rotation on one or more  axles  supported  by  a frame assembly for cutting and digging  into the ground as they are rotated. A plurality of elongated  teeth  or cutting tools are pivotally mounted for limited  pivotal  movement  on a rotatable hub, so when each tooth  or  cutting tool begins to dig into the ground as the hub  rotates  it to that position, the tooth or cutting tool itself   pivots  rearwardly  a  permitted  limited  distance against  the  pressure  and  resistance  of the ground. Such pivotal  movement  compresses  a  wedge shaped resilient and compressible member interposed between each pair of adjacent teeth  or  cutting  tools, which limits the rearward pivotal movement  of  such  tooth  or  cutting  tool  and which then propels  it  forward  as  the initial pressure or resistance dissipates  and  the compressible member expands back to its non-compressed state. This gives the cutting tools a kicking action  as  they  are worked into, through and up out of the soil to better loosen the soil and to better cut grasses and weeds.

Abstract: Abstract Precision 50% Duty Cycle Controller A sine wave locked in phase and frequency to a carrier having a high second harmonic content, carrying information on the magnitude of a parameter, is applied to an open loop operational amplifier which provides a trapezoidal waveform to a high speed, differential transistor pair which provides a pair of squarewave signals whose duty cycles are regulated by varying the threshold at which the differential pair switches.  The squarewaves may be used as a second-harmonic-free demodulating signal.  The fundamental premise is that if the amplitude levels of the squarewave are known to a high degree of accuracy, and they are equal in the positive and negative directions, then the average value is zero only for a 50% duty cycle.  A current regulator generates a selected current to a constant value with a high gain amplifier.  This current is switched from one side to the other of the differential pair by the trapezoidal waveform.  The voltage excursions may be controlled in equal amounts above and below zero by selecting the resistive values in the collector circuits of the differential pair to be of a magnitude which will accomplish that end.  The average value of the resulting squarewave is regulated to zero by integrating the voltage at the output of one of the collectors of the differential pair and varying the threshold at the base of the other transistor to obtain a 50% duty cycle.

Abstract: A building structure, particularly a road bridge structure, has an upper part (6-10) adapted to carry traffic, and a lower part (2) supporting the upper part. The two parts are separated by a non-adhesive, low friction membrane (1) having hood portions (4) fitting around anchorage blocks (3) projecting upwards from the surface of the lower part. The upper part comprises a course of pavement blocks (7) in which blocks are omitted to form a void around each anchorage block (3), the voids being filled with concrete (9). At least one asphalt layer (10) is laid on top of the pavement blocks (7). Liquids penetrating through the upper part are prevented by the membrane (1), including the hood portions (4) from penetrating into the lower part (2) and are drained off above the membrane (1). Horizontal forces resulting from traffic are transmitted via the asphalt layer (10), the pavement blocks (7), the concrete filling (9), the hood portions (4) and the anchorage blocks (3) to the lower part (2).
