Abstract: A reactor (16) for the remediation of polyfluoroalkyl- and/or microplastic-contaminated feedstocks includes an elongated, horizontally oriented, axially rotatable drum (34) having a shell (72) within a housing (32), with a feedstock input assembly (38) adjacent one end of the drum (34) and a feedstock output assembly (40) adjacent the opposite end thereof. A burner (94) within the housing (32) generates hot combustion gases which surround the drum (34) in order to conductively heat feedstock passing through the drum (34). The invention substantially completely remediates the feedstocks through volatilization of the contaminants.

Abstract: Processes of preparing defined monomer sequence polymers are disclosed, in which a backbone portion of the polymer is first prepared by performing one or more sequential monomeric coupling reactions with intervening membrane diafiltration purification/isolation steps, followed by a step of decorating the backbone portion with one or more side chains at predetermined positions along its length. The process represents an improvement on prior art techniques, which impose limitations on the size of the side chains that may be present. Defined monomer sequence polymers that are obtainable by the processes are also disclosed.

Abstract: A device and method for the display of images on a screen is described. The device includes a frame assembly configured to hold a screen. The frame assembly includes a hitch for attachment to a receiver hitch of a vehicle. The screen can be adjusted to face either a forward or rearward direction. The device further includes a stand. The stand may be configured to rest on the vehicle for projection onto the screen or rest on the ground. The stand supports a displaying device and is configured to adjust the elevation of the displaying device to affect the displayed image.

Abstract: The invention relates to a process for preparing a filtration membrane having an average molecular out-off of <1000 g/mol.

Abstract: A patient interface support that supports a patient interface of a PAP device and generates a pre-selected engagement pressure at the patient interface to create a seal between the patient interface and the patient's airflow passages when the interface support is in use while alleviating the strain on the patient's head. The patient interface support includes a base for attachment to a support surface; and, a support extension having a joint; a patient interface mount; and, biasing means. The joint movably connects the support extension to the base, the patient interface mount supports the patient interface, and the biasing means generates a pre-selected engagement pressure at the patient interface to create a seal between said patient interface and the patient's airflow passages when said interface support is in use.

Abstract: A user interface includes a user interface substrate and an associated integrated sensing electrode and backlight mask in the form of an opaque material having an aperture or otherwise light-transmissive portion therein. The integrated sensing electrode and backlight mask is positioned between the user interface substrate and a light source, such that indicia in the form of the aperture is visible at a surface of the user interface substrate when the light source is illuminated.

Abstract: An improved rotary shell or drum dryer (10) is provided having an elongated, horizontally disposed, axially rotatable shell (12) with product and air inlets (14, 18) and an outlet (16) at opposite ends of the shell. Internally, the dryer (10) includes axially spaced apart first and second drying sections (26, 28) each having a turbulator (30, 32) and a downstream serpentine flow section (34, 36). The turbulators (30, 32) are designed to divert portions of a product/airstream in different directions respectively to achieve the intense mixing similar to that obtained in an impingement dryer.

Abstract: A reporting system is described which provides current information on the progress of advertising campaigns, consumer feedback on the brands or products being advertised, or details on sample and premium distribution. Individuals perform campaign activities on behalf of an advertiser, such as by driving vehicles that have been custom fitted to display advertisement information on their exterior about the brands or products, or by otherwise interacting with targets of the campaign. The on-line reporting system provides means for the individual drivers to upload reports about the individuals' advertising activities into a computer system in a timely fashion, such as on a daily basis. The reporting system also provides means for the advertiser to review the reports received from the individual drivers and evaluate the effectiveness of the campaigns.

Abstract: A process for the purification of an oligonucleotide synthon is provided. The process comprises subjecting an organic solution comprising an oligonucleotide synthon and lower molecular weight impurities to nanofiltration whereby the ratio of an oligonucleotide synthon to lower molecular weight impurities in the solution is increased after the nanofiltration. Preferably, the oligonucleotide synthon is a nucleoside phosphoramidite or nucleoside H-phosphonate. The nanofiltration membrane is preferably a polyimide membrane having a molecular weight cut off of 400.

Abstract: Animal feeds and methods of forming animal feeds are provided wherein the feeds are formed by mixing poultry house litter and slaughterhouse wastewater sludges, followed by drying of the resulting mixture in a hot air convection rotary drum dryer. The resulting feed is high in fat and protein, and can be fed as a meal or in pelletized form. In a preferred embodiment, the feeds are formed by mixing litter comprising poultry manure and poultry feed with wastewater sludges comprising poultry fat, followed by drying in the rotary drum dryer. The feeds of the invention can be used to provide a high fat, high protein diet to any animal, particularly ruminants and aquatic animals.

Abstract: A method of reducing the concentration of at least one organic compound present in an aqueous feedstock, wherein said feedstock is supplied to one side of a substantially water-insoluble selectively permeable polymeric sheet or tubular membrane whose permeability to the or each said organic compound exceeds its permeability to chloride ion whilst simultaneously maintaining in contact with the other side of said membrane an aqueous reaction medium containing biologically active reaction means capable of reacting with said at least one compound after it permeates through the wall of the tubular membrane. Apparatus, preferably enclosed, for carrying into effect the method is also disclosed and permits treatment of waste waters containing volatile organic compounds. Modular bioreactor apparatus in the form of a cartridge containing a bundle of polymeric membrane tubes is also disclosed.
