Abstract:

A novel aldehyde-containing polymer (ACP) is prepared by reaction of a polysaccharide with periodate to introduce aldehyde groups onto the C. sub. 2 - C. sub. 3 carbon atoms and by introduction of ether and ester groups onto the pendant primary hydroxyl to modify solubility characteristics. The ACP is utilized to absorb nitrogen bases such as urea in vitro or in vivo.

Abstract:

The improved hemodialysis system utilizes a second polymeric membrane having dialyzate in contact with one surface and a urea decomposition solution in contact with the other surface. The membrane selectively passes urea from the dialyzate into the decomposition solution, while preventing passage of positively charged metal ions from the dialyzate into the solution and ammonium ions from the solution into the dialyzate.

International Classification:

A47B 900

US Classification:

108146

Abstract:

A load-supporting structure such as a table, seat, bench, shelf and the like, including at least one stationary member carrying a slidably adjustable surface which is adapted to support a load. The adjustable load-supporting surface has channel means associated therewith in which the stationary member is slidably disposed. A latching mechanism, pivotally carried by the load-supporting surface, is provided to frictionally engage the stationary member in the channel in order to hold the load-supporting surface in position on the stationary member. The latching mechanism has a positive clamping mechanical advantage so that the frictional pressure exerted by the latching mechanism on the stationary member is directly proportional to the amount of weight placed on the adjustable load-supporting surface. The latching mechanism is so constructed and arranged that upon the application of only a small amount of weight on the load-supporting surface, the frictional pressure of the latching mechanism on the stationary member is so great as to prevent disengagement of the latching mechanism and preclude movement of the adjustable load-supporting surface.

International Classification:

B32B 1902

US Classification:

428367

Abstract:

A thin, uniform, firmly adherent coating of metal gasification catalyst is applied to a carbon-graphite fiber by first coating the fiber with a film-forming polymer containing functional moieties capable of reaction with the catalytic metal ions. Multivalent metal cations such as calcium cross-link the polymer such as a polyacrylic acid to insolubilize the film by forming catalytic metal macro-salt links between adjacent polymer chains. The coated fibers are used as reinforcement for resin composites and will gasify upon combustion without evolving conductive airborne fragments.

International Classification:

US Classification:

Abstract:

A hand loom of improved and simplified construction in which the course of travel of the warp threads during the weaving operation is similar to conventional looms. However, the loom of the present invention is provided with a beater which is mounted for horizontal reciprocation so that the beater is maintained parallel and square with the warp threads at all times during such reciprocal movement. The beater is mounted directly adjacent the front harness at a point proximate the greatest opening of the shed. The present loom also has a plurality of harnesses of novel construction, with each of the harnesses being actuated by its own individual lifting means. Thus, a lifting lever, having an elongated arm and an upstanding leg, is positioned beneath each harness and is adapted to raise a selected harness when the outer end of the lever arm is depressed by the operator. Each harness is provided with upper and lower horizontally disposed heddle bars which extend through slots formed in the side rails of the harness and are slidably received in vertical channels in the walls of the castle to guide the harnesses during vertical movement. The loom is constructed so that the number of harnesses in the loom may be varied from two up to sixteen.

Abstract:

In a raw sewage treatment process of the type where settling tanks are used for the purpose of permitting the suspended matter in the raw sewage to be settled as well as to permit adsorption of the dissolved contaminants in the water of the sewage. The sludge, which settles down to the bottom of the settling tank is extracted, pyrolyzed and activated to form activated carbon and ash which is mixed with the sewage prior to its introduction into the settling tank, for the purposes mentioned. Because the sludge does not provide all of the activated carbon and ash required for adequate treatment of the raw sewage, it is necessary to add carbon to the process. In accordance with this invention, instead of expensive commercial carbon, coal is used to provide the carbon supplement.

Abstract:

Raw sewage may be presently treated by mixing screened raw sewage with activated carbon. The mixture is then allowed to stand in a first tank for a period required to settle the suspended matter to the bottom of the tank as a sludge. Thereafter, the remaining liquid is again mixed with activated carbon and the mixture is transferred to a secondary settling tank, where it is permitted to stand for a period required for the remaining floating material to settle as sludge and for adsorption of sewage carbon as well as other impurities to take place. The sludge from the bottom of both tanks is removed and pyrolyzed to form activated carbon and ash, which is mixed with the incoming raw sewage and also mixed with the liquid being transferred from the primary to the secondary settling tank. It has been found that the output obtained by the pyrolysis process contains an excess amount of ash. Removal of this excess amount of ash usually also results in removing an excess amount of carbon thereby requiring adding carbon to maintain the treatment process.

US Classification:

523205

Abstract:

The impact resistance of flame retardant composites, especially thermoplastic molding compounds containing over 60% hydrated mineral filler such as Al(OH). sub. 3 or Mg(OH). sub. 2 is improved by coating the filler with 1 to 20% of an elastomer. The composite will fail by crazing or shearing rather than by brittle fracture. A well bonded elastomeric interphase results by utilizing acidic substituted resins such as ethyl-hexyl acrylate-acrylic acid copolymers which bond to and are cross-linked by the basic filler particles. Further improvement in impact resistance is provided by incorporating 1 to 10% of a resin fiber reinforcement such as polyvinyl alcohol fibers that decompose to yield at least 30% water when heated to decomposition temperature.
