Patent number: 11939544Abstract: In chemical processes for cracking hydrocarbons, reactors are subject to coking. This results in carburization of the metal substrate for the reactor leading to a reduced reactor life. If the reactor is subject to a decoke process, followed by a steam scour and nitrogenating there is a reduced tendency to carburization of the metal substrate improving the reactor life.Type: GrantFiled: February 7, 2020Date of Patent: March 26, 2024Assignee: NOVA Chemicals (International) S.A.Inventors: Michael Koselek, Leslie Benum, Vasily Simanzhenkov, Hany Farag

Publication number: 20190309228Abstract: Crackers for hydrocarbon such as naphtha and C2-C4 paraffins contain a radiant section and a convection section. The exhaust gases leaving the radiant section pass through the convection. Generally fouling from the convection section was low relative to fouling (e.g., coke build up) in the radiant section. With improved metallurgy and operating conditions, the time between decokes of the radiant section has increased and now there is a need to reduce fouling from the convection section. This may be achieved by using stainless steel, and particularly high nickel, high chrome stainless steel in the passes in the convection section.Type: ApplicationFiled: March 18, 2019Publication date: October 10, 2019Applicant: NOVA Chemicals (International) S.A.Inventors: Vasily Simanzhenkov, Hany Farag, Leslie Benum, Michael Koselek, Kathleen Donnelly, Bolaji Olayiwola, Jeffrey Kluthe, Evan Mah, Jeffrey Xie

Patent number: 9590952Abstract: Lossy data stream decoder techniques are described herein. In response to a request for decoded content from a consuming application, a decoder may validate headers and identify portions of the data that are considered pertinent to the request. The decoder then performs lossy extraction to form incomplete data that is provided to the consuming application in response to the request. The full data for the data stream is not exposed to the consuming application or other downstream components. In this way, the consuming application is provided data sufficient to perform requested graphics processing and resource management operations, while at the same time the risk of piracy is mitigated since the consuming application is unable to get a full version of the data in the clear and the data have been validated by the decoder.Type: GrantFiled: September 5, 2014Date of Patent: March 7, 2017Assignee: Microsoft Technology Licensing, LLCInventors: Yongjun Wu, Fedir Yuriyovych Kyslov, Shyam Sadhwani, Samuel John Wenker, Brian P.

Patent number: 9430619Abstract: Innovations in the area of hardware-protected digital rights management (“DRM”) systems are presented. For example, a hardware-protected DRM system includes a trusted layer and untrusted layer. In the untrusted layer, a control module receives source media data that includes encrypted media data. The control module processes metadata about the media data. The metadata, possibly exposed by a module in the trusted layer, is not opaque within the untrusted layer. In the trusted layer, using key data, a module decrypts encrypted media data, which can be the encrypted media data from the source media data or a transcripted version thereof. A module in the trusted layer decodes the decrypted media data. A host decoder in the untrusted layer uses the metadata to manage at least some aspects of the decoding, rendering and display in the trusted layer, without exposure of decrypted media data or key data within the untrusted layer.Type: GrantFiled: September 10, 2014Date of Patent: August 30, 2016Assignee: Microsoft Technology Licensing, LLCInventors: Yongjun Wu, Shyam Sadhwani, Samuel J.

Publication number: 20130268755Abstract: Access to protected resources across client devices having different authentication systems is provided. An authorization provider creates cross-certificates to trusted public keys provided by resource protection providers. Each resource protection provider installs a digital certificate on a device. This digital certificate is signed by the resource protection provider, and includes on the device a private key which are used for client authentication. Client authentication is performed by a security module on the client device digitally signing an authentication request to the authorization provider using a protection provider module-specific digital signature algorithm and providing the signed request with the device's provider-digital certificate to the authorization provider. If the authorization provider verifies the signed request and that the digital certificate is part of the authentication PKI, then the client device will be authenticated.Type: ApplicationFiled: April 2, 2013Publication date: October 10, 2013Applicant: Microsoft CorporationInventors: John Carl Simmons, Hany Farag, Alexander Black Coyne
