  • Patent number: 11972310
    Abstract: Various examples described herein are directed to systems and methods for interfacing an analytics computing system with a remote resource. An analytics computing system may access data describing a multi-resource operation. The analytics computing system may execute a multi-resource application programming interface (API) service. The multi-resource API service may send a first trigger message to a public API of the first remote resource. The analytics computing system may send first data to the remote resource and may receive, from the remote resource, first result data describing a result of the first action performed at the first remote resource using the first data.

  • Patent number: 11400639
    Abstract: The invention relates to a process for the production of a high strength transparent high density polyethylene article comprising the steps of (i) heating a high density polyethylene (HDPE) to a temperature above the melting temperature (Tm) of the HDPE; (ii) molding the heated HDPE obtained in step (i) to form a hot molded HDPE article; (iii) cooling the hot molded HDPE article to a temperature below Tm to form a melt-crystallized HDPE article; (iv) stretching the melt-crystallized HDPE article to a total draw ratio of at least 5 comprising at least one stretching step of the article at a temperature T1 below the melting temperature Tm to a draw ratio (DR1) of at least 2 to form an oriented HDPE article, wherein the HDPE has a melt flow index (MFI) measured at 21.6 kg and 190° C. according to ASTM D1238 of at most 1.5 g/I Omin, an isotropic density measured according to ISO 1 183-1 A of at most 0.955 g/cm3 and a Tm measured according to ISO 1 1357-3 of greater than 130° C.
