Abstract: .alpha.-aminonitrile compounds derived from a fatty alkyl alkylene diamine containing two reactible amino functionalities are disclosed.

Abstract: A packaged aerosol preparation is provided for use in removing lint, hair and other particulate matter from fabrics. The sprayable liquid composition is packaged in a valve-equipped aerosol container. The composition includes an acrylic polymer or copolymer resin, a tackifier or plasticizer, and a liquified propellant consisting of either dimethyl ether or a mixture of dimethyl ether with a hydrocarbon propellant. The composition can be applied to absorbent substrates such as paper towels to provide an effective, disposable removal device.

Abstract: A novel method is provided for removing lint, hair, and other particulate matter from fabric articles such as clothing, upholstery, or draperies. A sprayable aerosol adhesive composition is applied to flexible sheet material, such as a paper towel, so as to splatter the surface of the sheet with tacky adherent globules of a tackified or plasticized resin without forming a continuous coating on the surface. The sprayed surface of the sheet is ready within 60 seconds for contacting with the fabric from which the particulate matter is to be removed.

Abstract: An erasable ink containing a thermoplastic block copolymer, pigment particles, and a solvent. In a preferred embodiment, an erasable ink requiring little or no pressurization is provided by employing a mixture of radial and linear block copolymers and a mixed solvent system falling within a specific range of solubility parameter. Polybutene and poly-alpha-methylstyrene are preferred additives to decrease smearing tendency.

Abstract: Tail-gate operating and locking apparatus for tail-gates utilized in refuse handling vehicles. The apparatus includes hydraulically operated means with a piston rod pivotally connected to the tail-gate and a cylinder pivotally connected to a latch mechanism for locking the tail-gate on the vehicle body. The latch mechanism comprises a bell-crank pivotally connected to the hydraulic cylinder and a locking element pivotally connected to the bell-crank and having a latching pin adapted to engage a hook secured to the tail-gate in a closed position thereof. A ramp element is rigidly attached to the vehicle body. The ramp element is provided with a cam surface to guide the latching pin during its reciprocating movement from and into engagement with the hook.

Abstract: This invention deals with novel sulfated condensation products of ethylene oxide with bases formed by condensing propylene oxide with propylene glycol, and having a molecular weight of about 11.phi..phi. to 48.phi..phi.. The sulfated condensation products are useful as components in hair shampoo systems to provide an after-shampoo conditioning effect.

Abstract: This invention deals with novel sulfated copolymers of hydroxyethyl methacrylate and alkyl esters of acrylic acid and sulfated copolymers of hydroxyethyl acrylate and alkyl esters of methacrylic acid. The copolymers are useful as components in aqueous hair shampoo systems to provide an after-shampoo conditioning effect.

Abstract: This invention relates to materials and methods used in informational, testing, educational, amusement and other paper-based feedback systems embodying invisible images comprising a color-forming reactant material which can be rendered temporarily visible by the application of a coreactant. The systems may also include visible printed images and are suitable for multiple reuse.

Abstract: This invention relates to alkali developable, paper-based systems printed with invisible phenolphthalein inks and made reusable through many development cycles by employing critical concentrations of dye reactants in conjunction with a paper having a defined water soluble acidity-alkalinity.

Abstract: A synthetic polymer-based chewing gum having a prolonged flavor release due to the inclusion of molasses.

Abstract: Ink compositions for use in capillary type writing instruments containing quaternary ammonium of the formula:RCH.sub.2 N(CH.sub.3).sub.3.sup.+ X.sup.-whereinR is --CH.sub.2 OH or --COOH, andX is --OH, --Cl, --Br, or --I.These ink compositions, when used in capillary type writing instruments, allow rejuvenation of writing points which have dried out from exposure to the atmosphere.

Abstract: Novel copolymerizable esters of cinnamic acid or an .omega.-alkenoic acid of from 4 to 18 carbon atoms, such as undecylenic acid, with certain hydroxyalkane sulfonic acids, such as isethionic acid, are described together with processes of making them and copolymers thereof. These novel copolymerizable esters may be made by reaction of the .omega.-alkenoic or cinnamic acid with the hydroxyalkane sulfonic acid or a sultone, such as propane sultone. These novel ester are useful as copolymerizable surfactants in the emulsion polymerization of ethylenically unsaturated monomers; particularly for the production of self-stabilizing latices of polymeric materials possessing excellent mechanical stability and from which can be deposited films having improved adhesion, pigment wetting and bonding properties and greatly improved resistance to water.
