Abstract: Hydraulic pumping systems that reduce wear within a reciprocating piston pump are described. The system includes a hydraulic drive system having a first drive piston, a second drive piston and a work piston within a work cylinder having first and second working sides. The work piston connects each of the first and second drive pistons via first and second piston rods. The work chamber is configured to receive a fluid/gas to be pumped on the first and second working sides of the work piston and expel the fluid/gas from the first and second working sides of the work piston. A hydraulic fluid control system is configured to alternately direct hydraulic fluid to respective working sides of the first and second drive pistons such that the first and second piston rods are in tension during each working stroke of the work piston.

Abstract: A streaming server receives a first request to view the media item from the client device via a connection between the client device and the streaming server. An encrypted portion of the media item is provided to the client device. A cryptography key is sent to the client device for decrypting the encrypted portion of the media item by the client device to facilitate the playback of the decrypted portion of the media item. A verification is received to determine whether the client device is authorized to play the decrypted media item.

Abstract: Screens for conical mills and an improved gearbox and housing for such conical mills are shown and described. The screens are frusto-conically-shaped and include a tapered sidewall with a plurality of openings in the sidewall that may be of uniform size. Each opening is separated from adjacent openings by spacing distances which are shorter at the top of the tapered sidewall and longer at the bottom of the tapered sidewall to thereby reduce the residence time of the powder being milled at the top of the tapered sidewall and to increase the residence time of the powder being milled at the bottom of the tapered sidewall.

Abstract: A method receives, by a processing device of a streaming server, a first request to view the media item from the client device via a connection between the client device and the streaming server. Prior to a verification that the client device is authorized to play the media item, the method provides an encrypted portion of the media item to the client device via the connection between the client device and the streaming server. Responsive to the verification that the client device is authorized to play the media item, the method sends, by the processing device via the connection between the client device and the streaming server, a cryptography key for decrypting the encrypted portion of the media item by the client device to facilitate the playback of the decrypted portion of the media item.

Abstract: Implementations disclose merged video streaming, authorization, and metadata request. A method includes receiving, by a streaming server, a first request to view a media item from a client device via a connection between the client device and the streaming server, and sending a second request to an authorization server to verify that the client device is authorized to play the media item. The method further includes: prior to receiving a response from the authorization server, providing an encrypted portion of the media item to the client device via the connection, receiving, from the authorization server, a verification that the client device is authorized to play the media item, and sending, via the connection between the client device and the streaming server, a cryptography key for decrypting the encrypted portion of the media item to the client device.

Abstract: Techniques for clients and servers to use the web authoring extensions, and in particular, extended error handling to allow servers to provider richer web authoring error information to clients. One technique includes sending an authoring request to a server, receiving a response message with extended error information by a client, and sending the extended error information to an application program. Other embodiments are described and claimed.
