Abstract: A system and method for determining organic chlorine content in petroleum or petrochemical streams are disclosed. The system comprises an injection module configured to introduce a sample, consisting of a 204° C. cut of washed naphtha or equivalent, into a gas stream; a gas supply unit configured to deliver a gas mixture of approximately 80% oxygen and 20% inert gas selected from argon, helium, or nitrogen, into the injection module; a combustion unit maintained at approximately 800° C. to convert chlorine in the sample to chloride and oxychlorides; a titration cell, comprising: an electrolyte containing 75% acetic acid in water, a silver ion solution to react with chloride ions in the sample, resulting in a measurable electrochemical reaction; and a microcoulometer configured to measure the electric current required to replace consumed silver ions in the titration cell, wherein the measured current is indicative of the organic chlorine content.

Abstract: A repository of replicated chunk files is analyzed to identify chunk files that meet at least a portion of combination criteria. Selected chunk files are associated together under a data protection grouping container. Erasure coding is applied to the data protection grouping container including by utilizing the selected chunk files as different data stripes of the erasure coding and generating one or more parity stripes based on the different data stripes.

Abstract: A remote data recovery system is determined to be unsuitable for communications. A stream of source system storage changes associated with an object is received at a backup system from a source system while the remote data recovery system is unsuitable for communications. The backup system is utilized to generate one or more reference restoration points based on the stream of source system storage changes associated with the object. The remote data recovery system is determined to be suitable for communications. In response to determining that the remote data recovery system is suitable for communications, a hot standby of the object hosted by the remote data recovery system is updated to a reference restoration point generated by the backup system prior to the remote data recovery system becoming suitable for communications.

Abstract: A mechanism for storing indexing updates is described. A secondary storage system is configured to store a backup of a primary storage system. A plurality of different indexing updates of a data repository associated with the secondary storage system is received. An indexing update may include metadata and/or updates to the metadata for a data item in the backup. The indexing updates may be obtained from an indexing process. At least a portion of the indexing updates are sent for storage in an intermediate store. An indication to commit the indexing updates is received. In response, the indexing updates including the at least the portion of the indexing updates are requested to be committed. The indexing updates batched together into a batch to be committed to a metadata store.

Abstract: A stream of source system storage changes associated with an object are received at a backup system from a source system. The source system storage changes associated with the object are provided to a remote data recovery system. The remote data recovery system is configured to store the provided source system storage changes associated with the object. The backup system is utilized to generate one or more reference restoration points based on the stream of source system storage changes associated with the object.

Abstract: Metadata associated with content stored in a corresponding primary storage system is received receiving from each secondary storage cluster of a plurality of different secondary storage clusters included in different storage domains. The metadata received from the plurality of different secondary storage clusters is stored and indexed together. A unified metadata search interface is provided for stored data of the corresponding primary storage systems and the plurality of different secondary storage clusters of the different storage domains.

Abstract: A chemi-luminescent cheek retractor, wherein, the chemi-luminiscence is not localized to a specific location but the whole cheek retractor has multiple compartments to provide adequate and uniform illumination. Further, the cheek retractor is inflated with chemi-luminescent reagent and triggered by triggering agent thus allowing a chemi-luminescent reaction. The chamber is made of transparent heat resistant flexible material to withstand the heat generated during the chemi-luminescent reaction. An angular oris is lined with a reflective coating on the mouth facing surface to aid in better and uniform illumination; one detachable extendable flange is provided to abet attachments for providing multi-functionality, the purpose of detachable components is to facilitate easy cleaning and sterilization.
