  • Patent number: 11447080
    Abstract: The present disclosure provides a wire harness retainer assembly. The wire harness retainer assembly includes a stud including a first end and a second end opposite the first end. The stud includes a cavity between the first end and the second end. The stud is configured to receive a wire harness retainer thereon. The wire harness retainer assembly also includes a plug configured to be positioned at least partially within the cavity to lock the wire harness retainer onto the stud.
    Type: Grant

  • Patent number: 5310529
    Abstract: There is disclosed an improved process for the preparation of phosphorus trichloride wherein elemental phosphorus is caused to react with chlorine. The improvement comprises continuous, high speed analysis of the contents of the reactor whereby the reaction is controlled to produce less phosphorus pentachloride and other by-products. The analysis is performed by a laser Raman spectrometer associated with an optrode having a remotely located probe head and a circulating sampling system to continuously provide fresh sample to the probe head continuously. Also disclosed is apparatus for the automatic control of the reaction by control of the reactant feed to the reactor in response to the on-line, continuous analysis of the reactor contents.

  • Patent number: 5208000
    Abstract: There is disclosed a process for the controlled hydrolysis of phosphorus trichloride which avoids the formation of lower oxides of phosphorus, phophines and diphosphines wherein phosphorus pentachloride is added to the phosphorus trichloride from about 20 to about 90 percent by weight of the phosphorus trichloride and then water in the form of finely divided droplets is added over the surface of the phosphorus trichloride while the temperature is controlled to below about 80.degree. C.

  • Patent number: 4948516
    Abstract: A method of disposing of wastes containing heavy metal compounds by neutralizing the wastes, oxidizing the neutralized wastes, then solidifying the oxidized wastes using conventional mineral binding agents such as Portland cement. This method is of particular interest in treating arsenic sulfide containing aqueous sludges produced in the manufacture of phosphoric acid.
