  • Patent number: 10283996
    Abstract: Packaging is disclosed. The packaging may include a charging element to charge an electronic device contained within the packaging. The charging may be performed by inductive charging. The packaging may include a magnet to position and retain an item within the packaging. The packaging may include protective surfaces formed of microfiber to help protect an item contained therein. The microfiber may be debossed around its periphery to minimize interruption between the microfiber and an underlying surface to which it is applied.
    Type: Grant
    Filed: August 25, 2015
    Date of Patent: May 7, 2019
    Assignee: Apple Inc.

  • Patent number: 6242598
    Abstract: A process for preparing 2-(2,4-dihydroxyphenyl)-4.6-diaryl-s-triazines in three steps starting with cyanuric chloride is described. Step 1 involves the nucleophilic (basic) displacement of one chlorine atom with a phenolic moiety. Step 2 involves a Friedel-Crafts reaction using a Lewis acid catalyst (preferably aluminum chloride) to replace the remaining two chlorine atoms with aryl groups such as xylyl. Finally, step 3 involves replacing the phenolic moiety with resorcinol using either a Lewis acid or protic acid catalyst or combinations thereof. Some additional processes only peripherally related to the three-step process outlined above are also described for the preparation of various s-triazine compounds. The s-triazines prepared are useful as UV absorbers for the stabilization of organic substrates against the adverse effects of actinic light.

  • Patent number: 5254635
    Abstract: A dibenzylthiuram sulphid such as tetrabenzylthiuram disulphide is combined with a dihydrocarbyl xanthogen polysulphide and/or a xanthate to provide a composition which has good properties as an accelerator in rubber vulcanisation, without providing harmful nitrosatables.

    Date of Patent: October 19, 1993
    Assignee: Robinson Brothers Limited
    Inventors: Arthur Stevenson, Ranvir S. Virdi
  • Patent number: 4695609
    Abstract: A novel mixture comprises a dihydrocarbyl xanthogen polysulphide and a xanthate selected from metal hydrocarbylxanthates and dihydrocarbylxanthates. Such a mixture can be used to cure a vulcanizable rubber composition containing less than 0.4 parts by weight of nitrosatable materials per 100 parts by weight rubber; the use of toxic conventional nitrogen-containing accelerators such as amines can be avoided.

  • Patent number: 3966601
    Abstract: A purification process for industrial effluent containing dissolved dithiocarbamate is described. Before discharging the effluent, it is mixed at pH 6 to 8 with a soluble heavy metal salt and heavy metal dithiocarbamate thereby precipitated and the precipitate is separated from the effluent. By the process poisoning of fish in water courses into which the effluents are discharged can be avoided as can malfunctioning of sewage treatment processes handling the effluents.
