  • Partial oxidation process using a nozzle for achieving constant mixing energy
    Patent number: 4762532
    Abstract: This invention relates to a two-fluid nozzle which is adjustable to provide a substantially constant mixing energy. Adjustment of the two-fluid nozzle is made in accordance with the pressure and mass flow values of the liquid and gas fed to the nozzle. A microprocessor calculates the mixing energy from these values and provides an output to the nozzle to adjust it should its mixing energy be in variance with a pre-selected mixing energy.

  • Process for reducing the 4-carboxybenzaldehyde content of a crude terephthalic acid product
    Patent number: 4670587
    Abstract: This invention relates to a process for the purification of crude terephtic acid. The process includes heating the crude acid on a first plate and locating a second plate adjacent the first plate whereby vapors emanating from the crude acid form a sublimate on the second plate. The principal impurity removed is 4-carboxybenzaldehyde. The crude acid produced is applied to the first plate as a layer having a thickness of about 2 to about 5 mms thick and heated to a temperature of from about 180.degree. to about 220.degree. C. The upper plate is not heated except by the convective heat transfer and the heat of sublimation provided by the vapor moving from the crude acid layer to the second plate.

  • Nozzle
    Patent number: 4669665
    Abstract: This invention relates to a nozzle for dispensing and aerating liquids. The nozzle provides for the formation of a substantially hollow conical vortex which aspirates air into its interior. The vortex is formed within a chamber so that the base of the vortex impinges upon the chamber walls. This impingment results in the formation of a turbulent film which, when brought in contact with the aspirated air, results in aeration of the liquid forming the film. A foam like characteristic is given the liquid by the entrapment of the air as the liquid is dispensed.

  • Liquid level indicator and valve
    Patent number: 4611623
    Abstract: This invention relates to a device for monitoring a liquid level in a first vessel and for effecting the transfer of liquid to the first vessel from a second vessel upon the liquid level in the first vessel reaching a predetermined minimum point. The device comprises a pressure sensitive appliance which is in contact with a gas in a first and in a second chamber. The pressure sensitive appliance is movable between a first position and a second position. The second position is towards the first chamber and occurs when the pressure in the first chamber is lower than the pressure in the second chamber. The first chamber is vented to an ambient atmosphere. A conduit is also provided which is in gas communication with the first chamber and with the interior of the second vessel.

  • Vented closure
    Patent number: 4427126
    Abstract: A thermoplastic closure suitable for fitment to a threaded container neck is disclosed. The closure has at least one venting groove in the sidewall traversing the closure thread. A rigidifying means is provided at the point of traverse of the venting groove and the closure thread. This rigidifying means has a perpendicular height measured from the sidewall less than the perpendicular height of the closure thread also measured from the sidewall. The rigidifying means provides hoop strength to the closure sidewall.

  • Method and apparatus for threading closures
    Patent number: 4399679
    Abstract: An apparatus for forming a thread about the sidewall of a closure is disclosed. The apparatus features a nest for holding the closure and a circular tool fittable within the closure while it is in the nest. The nest and the circular tool have cooperating die means so that when the circular tool achieves planetary motion the die means coact one with the other to form a thread on the closure.
