Abstract: Apparatus for controlling the air supply to the intake manifold of an internal combustion engine having an intake system comprising a carburetor, the carburetor having a throttle, means for admitting air from the atmosphere and conducting the air to the carburetor for mixing with fuel, and conduit means for conducting the mixture of air and fuel from the carburetor to the intake manifold, the apparatus comprising auxiliary conduit means for conducting fuel--free air into the engine, the auxiliary conduit means communicating with the intake system at a point downstream of the throttle, a displaceable member associated with the auxiliary conduit means, the displaceable member being displaceable between a position in which the member blocks the access of air from the auxiliary conduit to the intake manifold and positions in which the member at least partly opens access of air from the auxiliary conduit to the intake manifold, an electromagnet associated with the displaceable member for controlling the displaceme

Abstract: A process for producing a flocked fabric laminate by coating an auxiliary substrate with a temporary adhesive binder, flocking the coated auxiliary substrate with flock fibers, coating the flock fibers with a curable flock adhesive binder, marrying a substrate backing layer to the binder coated flock, permanently setting the flock adhesive binder, and then removing the auxiliary substrate from the fabric laminate whereby the flock remains secured to the substrate backing layer is disclosed. Flocked fabric laminates obtained by such method are also described.

Abstract: A process for producing a laminate by coating a continuous first layer of a film forming material onto a release sheet, distributing flock fibers uniformly onto the first layer, drying the first layer to form a film and secure the flock fibers thereto in a substantially upstanding position, coating the tips of the flock fibers with a flock adhesive, marrying the flocked film to a substrate backing layer such that the coated tips contact the said substrate layer, permanently setting the flock adhesive, and then removing the release sheet. Laminates obtained by such method are also described.

Abstract: A process for rendering cellulose and cellulose containing fabrics fire resistant by first impregnating the fibers with a solution of an aminoplast resin, an acid and an effective amount of a dialkyl phosphono methylol alkylamide to produce fire retardancy in the resulting fabric having the formula ##STR1## wherein R is lower alkyl having 1 to 6 carbon atoms and x is an integer from 1 to 3 and polymerizing the resin while the fibers are wet and swollen. The fabric is then cured, washed and dried. The fabric obtained from this process possesses high fire-retardancy values, soft hand, and tensile values similar to that of the untreated fabric.

Abstract: Textile fabric previously impregnated with THPOH is treated to retard inflammability by passage therethrough of toxic ammonia gas in apparatus which permits the THPOH--NH.sub.3 reaction to be carried out in a sealed chamber preventing escape of the toxic gas. The invention operates to confine the gas in a flow path whereby substantially all of the gas flowing through the apparatus is passed directly through the fabric. The fabric is passed through the sealed chamber by means of gas-tight entrance and exit portals. A perforated drum is mounted within the chamber and the fabric is passed about the perimeter of the drum. Sealing elements cooperating with the drum confine ammonia gas introduced into the interior of the drum to flow only through those perforations covered by fabric.

Abstract: A creaseproofing composition prepared by reacting urea with a monoalkyl ether of an ethylene glycol having 1 to 10 ethyleneoxy groups, removing the excess monoalkyl ether and then reacting the remaining mixture without isolation of any carbamate formed with formaldehyde. The composition obtained and its method of use as a creaseproofing chemical are described.

Abstract: A stable, high concentration urea-formaldehyde composition having a urea to formaldehyde ratio from about 1:1.5 to 1:2.8, a free formaldehyde content of less than 3% and an active ingredient concentration of greater than 60%. Additionally, a method for making the composition comprising adjusting the pH of a mixture of urea and formaldehyde having a urea/formaldehyde ratio greater than about 1:4 to a value greater than about 10, reacting the mixture of the temperature from about 100.degree. to 230.degree.F and adjusting the urea/formaldehyde ratio during the reaction time to the desired final value. The composition is useful for imparting crease and wrinkle resistance to textile fabrics, coating of paper, and bonding of wood.

Abstract: The invention comprises a method for texturizing a flocked fabric by first wetting the flocked portion and/or its supporting fabric and adhesive, orienting the wet flock in a pre-determined design pattern by continuously, rapidly and vigorously contacting the flock with a plurality of flexible beaters and drying the fabric.

Abstract: A process for making a porous flocked fabric by coating one side of a loosely interlaced substrate with a flock binder. The coated side of the substrate is flocked and the binder is allowed to migrate or strike through to the opposite side of the substrate. A particulate material, e.g., flock, ground flock, talc, etc., is then applied to said opposite side and the binder is permanently set. The product obtained by this process is also described.

Abstract: An improved guide assembly for an apparatus for the fluid treatment of fabrics in rope form is provided which comprises a pair of cooperating comb-shaped guide members and driving means of said guide members in timed relationship in longitudinal and transverse reciprocations.

Abstract: A process for rendering cellulose and cellulose containing fabrics fire resistant by first impregnating the fibers with an aminoplast resin and polymerizing the resin while the fibers are wet and swollen. Thereafter, the fabric is impregnated with tetrakis (hydroxymethyl) phosphonium hydroxide, cured, washed and dried. The fabric obtained from this process possesses high fire-retardency values, soft hand, and tensile values similar to that of the untreated fabric.
