Abstract: A plastic extruder system having a barrel and a shell with heat exchange elements surrounding the barrel is disclosed. Two thermocouples are provided, one for sensing the temperature of the inner surface of the barrel and the other for sensing the temperature of the shell. A system controller, into which a desired barrel setpoint temperature can be set and stored, receives and stores the independent temperature signals from the thermocouples and controls the heat exchange elements to automatically maintain the temperature of the extruder barrel close to the desired barrel setpoint temperature.

The new dye is intended to replace the widely used paper dye known as C.I. Direct Black 38--a dye synthesized from an intermediate (benzidine) whose use is being curtailed because it is a known carcinogen.

Abstract: The specification is directed to a method for enhancing the light fastness of dyed and undyed nylon textile fibers and to the treated fibers produced thereby. The beneficial effect is obtained by applying at least 3 parts per million colloidal phosphate to the fiber by exhaustion from an aqueous medium; the treatment being effected either before dyeing, simultaneously with or after the dye has been applied to the fiber.

Abstract: The application is concerned with new pyrazolone compounds having the structure: ##STR1## wherein R is hydrogen or halogen (especially fluorine, bromine and chlorine) and R.sub.1 and R.sub.2 independently of one another are hydrogen or halogen (especially bromine and chlorine) and R.sub.3 is lower alkyl (especially methyl, ethyl, propyl and butyl). The compounds are useful in heat transfer printing of polyester fabrics and impart yellow shades thereto. The application discloses a method of making the new compounds and discusses the utilization of the compounds in the heat transfer printing of polyester fabrics, in the preparation of ink formulations, and in making transfer sheets for heat transfer printing.

Abstract: This invention pertains to transfer sheets which comprise a flexible nontextile substrate in sheet, roll or web form having an all-over or discontinuous printed pattern effect thereon with the pattern being formed by a film of a dried ink formulation adapted for heat transfer printing of synthetic textiles in which the ink contains a red azo acylanilide of the formula ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4, which are the same or different, are alkyl. These transfer sheets can be used for the heat transfer printing of synthetic textile fibers such polyester textile fibers and nylon textile fibers.

Abstract: A projectile for use in a loom in which filling picks are inserted into a warp shed from an outside supply source comprising an elongated body having an inlet opening at one of its ends and an outlet opening at the opposite end thereof. Inside of the body there is an elongated cavity which extends along the longitudinal axis of the body. This cavity is divided into two (2) filling storage chambers by a perforated partition which extends across the longitudinal axis at an angle of less than 90 degrees therefrom. The inlet opening for one of these chambers constitutes the outlet opening for the other chamber, for the air flow which is used to deposit filling yarn into the chambers of the projectile.

Abstract: New yellow azo pyrazolone compounds having the structure ##STR1## wherein R is halogen and R.sub.1 and R.sub.2 are hydrogen, lower alkyl or halogen. The compounds are useful as yellow dyes in heat transfer printing of synthetic fabrics.

Abstract: A projectile launching and receiving apparatus for a pneumatic loom which includes a bore for receiving the projectile, a pneumatic launching chamber connected to the bore which is pressurized for launching the projectile, a passageway for guiding filling yarn from an outer opening to the bore, and valve means for blocking the passageway between the opening and pressure chamber to prevent filling yarn from being blown toward the outer opening.

Abstract: A projectile for use in an outside filling supply loom, comprising an elongated body having an inlet opening at one end and an outlet opening at the opposite end. A flat filling storage chamber is located within the body and is connected to the inlet opening. A passageway located between the storage chamber and outer surface of the body is connected to the outlet opening and the storage chamber.

Abstract: The application is concerned with the composition of matter composed of a brown dye of the formula: ##STR1## and a blue dye of the formula: ##STR2## useful in marking heat transfer prints in black shades; heat transfer sheets carrying such composition; inks for printing the transfer sheets; a heat transfer process for black prints on polyester and novel heat transfer printed fabrics.
