Abstract: Declining rate filtration systems using influent siphoning for influent flow to a bed of particulate filter media are improved by using at least two influent siphons with each filter bed. In use of such improved systems, influent is siphoned from a flume source or the like to the filter bed after backwashing of the filter media through a first siphon and, thereafter as headloss in the filter bed increases, further influent from the source is siphoned to the filter bed through a second siphon that has an effective minimum cross-sectional area substantially greater than that of the first siphon.

Title: Digital communications systems
Inventor: MCCABE DAVID J
IPC: A43D119/00
Filed: 1992-02-11
Abstract: Corruption in digital data communications systems is detected, at the receiving end, by taking a number of samples of the received signal within each bit period.   Flip flops (4, 7 and 8) are used to take samples from the digitised received signal as follows: flip flop (4), a mid bit sample indicative of the value of the centre of the bit; flip flop (7), a pre-mid sample taken within the bit period before the mid-bit sample; and flip flop (8), a post-mid sample taken within the bit period after the mid-bit sample. Gating circuitry (23, 24, 25) is used to analyse the three samples and give a "good" or "bad" output signal to register 11 as a result of the analysis. Corruption is judged to be present if any one of the samples has a different value to the others.

Abstract: ADAPTIVE TRANSMISSION SHIFT PRESSURE CONTROL WITH CLOSED-LOOP COMPENSATION            Abstract of the Disclosure An adaptive transmission pressure control based on a measured interval of speed ratio progression includes a closed-loop control which compensates for factors that tend to extend the speed ratio progression.  The control detects the rate of speed ratio progression during a first portion of the inertia phase of the shift, and employs closed-loop pressure control to maintain the detected rate of progression through completion of the shift.  This ensures that the measured progression interval will accurately reflect the relationship between the scheduled pressure and the resulting shift ratio progression, regardless of factors which would otherwise influence the measured shift progression interval.  Consequently, the correlation between shift quality and the measured shift progression interval is preserved.

Filed: 1993-02-15
Abstract: A conversion replacement apparatus for HID screw-in mercury vapor, metal halide or high or low pressure sodium lamps utilizes the reflector typically employed with such lamps.  The HID lamp is removed from the reflector.  A fluorescent lamp support frame then is attached to the base end of the inside of the reflector to extend to a point substantially one-fourth to one-half of the distance between the base end and the light-emitting end of the reflector.   The support includes a plurality of extensions for holding the bases of compact fluorescent  lamps arranged  in a general star configuration around the center line of the reflector. The  extensions  are  bent  at  an  angle  to  cause  the  compact fluorescent lamps to follow the outwardly-flared inside surface of the reflector.  Ballasts for the lamps are located in a housing attached to the base end of the reflector.  Additional controls are provided for selectively supplying power to different ones of the ballasts for the fluorescent lamps to effectively provide "dimming" of the overall light output from the fixture.

Filed: 1993-04-13
Abstract: ABSTRACT AIR SEPARATION   Air is bled from the air compressor 4 of a gas turbine 2 and is cooled in heat exchanger 16 to a temperature suitable for its separation by rectification.  The air is separated in a double rectification column 22 comprising a lower pressure rectification column 26, operating at a pressure at its top of at least 2 bar, and a higher pressure rectification column 24.  Gaseous oxygen and nitrogen products are withdrawn from the lower pressure rectification column 26 through outlets 39 and 41 respectively and are warmed countercurrently to the air stream in the heat exchanger 16.  Two nitrogen side streams at different temperature from one another are withdrawn from the heat exchanger 16. The warmer stream is expanded in an expansion turbine 50, the colder stream in an expansion turbine 48.  Both the expanded nitrogen streams are returned to the heat exchanger 16 and warmed therein.  Part of the warmed nitrogen product stream is compressed in a compressor 52, is cooled in the heat exchanger 16 and is condensed in a condenser-reboiler 46 to form a liquid nitrogen product.              .

Title: Low temperature separation of bitumen from oilsands
Inventor: KESSICK MICHAEL A
IPC: C10G1/04
Filed: 1993-07-23
Abstract: Bitumen is recovered from oil sands in an ambient temperature procedure in which the oil sands first are subjected to attrition in the presence of an aqueous sodium hydroxide solution to form a slurry of pH at least about 11.5. Sand, freed from bitumen, usually is separated from the slurry, which then is diluted with further quantities of aqueous sodium hydroxide solution while maintaining the pH value, so as to provide the bitumen in a form which can be separated from the aqueous phase by flotation. The bitumen is floated off from the aqueous phase comprising a clay suspension and then forwarded to an upgrading operation. A second bitumen flotation also may be effected following addition of calcium hydroxide to the remaining aqueous phase. The clay suspension may be flocculated and dewatered and the resulting sodium hydroxide solution recycled to the attrition and/or dilution steps.

Abstract: A support beam for a storage rack has a tubular profile, which defines a ledge opening upwardly and inwardly, and which defines a generally flat, indicia-receiving surface facing outwardly and either downwardly or upwardly at an angle from about 20° to about 70° relative to a vertical plane.  Alternatively, the tubular profile may define two such surfaces defining an obtuse angle relative to each other, namely an upper surface at an angle from about 20° to about 45° relative thereto and a lower surface at an angle from about 45° to about 70° relative thereto, or a generally arcuate, indicia-receiving surface having a suitable measurement. The indicia-receiving surface enables a person who is standing, or who is sitting on a lift truck, to have a generally perpendicular line of sight to such surface. The support beam may also be used in combination with a properly positioned fire extinguishing device to extinguish a fire in a supported load.  When the fire extinguisher is activated, the fluid that is discharged impinges off the indicia-receiving surface, which may be inclined or curved, and onto the load.

Title: Alloantigen testing by binding assay
Inventor: POULETTY PHILIPPE J
IPC: G01N33/569
Filed: 1992-12-09
Abstract: The presence of alloantigen alleles or antibodies to alloantigen alleles is determined by employing a support to which alloantigen alleles are bound, and combining a specimen which contains either the alloantigen alleles or antibodies to alloantigen alleles with a reagent comprising antibodies to the alloantigen allele(s) of interest. By combining the specimen, reagent and support, and determining the amount of antibody which binds to the support as compared to a negative control, the presence of the alloantigen antigen or anti-alloantigen is related to a reduced amount of antibody binding to the support. The amount of antibody may be determined by any convenient assay.
