A method of and apparatus for efficiently providing video on demand services to a cable television subscriber. The provider system consists of two major subsystems. The first subsystem, called a video server, streams video to video on demand subscribers through the cable television network. The second subsystem, called the transaction server, performs virtually all remaining provider functions including, security, accounting, storage and spooling of video data, etc. The transaction server preferably uses a large scale mainframe computer. The video server subsystem may be a partitioned portion of same large scale mainframe computer.

The invention relates to a device for tensioning the retractable top of a motor vehicle (1). Said top comprises a front element (2) and a rear element (3) which are displaceable between the closed and opened positions thereof. The displacement of said elements is controlled by two articulated arms (6, 7). The inventive device is provided with arresting means (9) carried by the first arm (7) in such a way that is abuts against the second arm (6) when two elements (2, 3) of the top are relatively near to the closed position thereof. The arresting means (9) are provided with elastic means able to resist to the relative motion of the arms (6, 7) when the elements of the top (2, 3) are displaced from the relative position thereof, which is near to the closed position, and move towards said closed position.

An apparatus for and method of permitting a CORBA user terminal to request services from an enterprise server having XATMI applications, wherein the process is controlled by an integrated two-phase commit protocol. The service request is generated and transmitted to a server. The user terminal transmits a prepare. When the server acknowledges the prepare, a log entry is made. The user terminal transfers a commit which when acknowledged by the server causes deletion of the log entry. Each of the request/acknowledge communications is performed in both CORBA and XATMI protocols.

A frame assembly forming a portion of a rowing accessory is to be mounted within a watercraft, to which frame assembly is attached a seat and oars. The frame assembly comprises first and second frame members each having the general shape of a winged U. First and second wing portions of each frame member extend outwardly from upper ends of the frame members. A track assembly has a beam attached to lower portions of the frame members at spaced apart connection points along the length of the beam. A seat assembly attaches to and slides along the beam. First and second hinge plates each have a first end attached at an outboard end of one wing portion of the first frame member, and a second end attached at an outboard end of one wing portion of the second frame member.

A personal flotation unit for supporting a person in a generally sitting position in the water, with the person's head and part of the person's torso above the water has a rear panel and a front panel each made from a flexible flotation material. A fabric seat is connected between bottom edges of the panels. Left edges of the panels are connected by strapping of some kind, as are the right edges of the panels. The seat and the strapping cooperate to form the panels into a diaper or pair of shorts that provides flotation allowing the user to sit in an upright position in water. Preferably the front panel has a T shape with arms that during use are bent backwards by the strapping to provide lateral flotation support for the wearer.

A system for testing a microcircuit having a center ground (CG) terminal has an insert for electrically connecting the CG terminal to a ground contact on a load board. The insert is held within a housing by compression and frictional interaction between a resilient projection carried by the insert and a slot in a wall of an aperture holding the insert.

Cable supported hook apparatus provides a U-shaped upward facing opening for transporting a truss. A cam pivotably mounted opposite the opening has a serrated edge opposite a handle. A slot in the opening permits a spring to urge the cam from a released orientation to an engaged orientation with the serrated edge extending through the slot. In the released orientation, a knob retractable spring driven pin extension can extend through a hole in the cam and secure it in place. In use, the handle is first used to rotate the cam to the released and secured orientation. After engagement with the truss, the extension is retracted by the knob which permits the cam to engage the truss. After transportation a release cable rotates the cam to the released and secured orientation to free the truss.

A device for securing a sign to a mullion is provided. The device includes first and second body portions, and a tensioner operatively uniting same. The first body portion is characterized by adjacent mullion receiving elements and a sign support structure. A first mullion receiving element includes a substantially planar member receivable adjacent a mullion face. A second mullion receiving element extends from the first mullion receiving element for tensioned engagement with a first lateral mullion surface of opposingly paired lateral mullion surfaces adjacent the mullion face. The sign support structure is spaced apart and extends from the first mullion receiving element so as to thereby delimit a channel passing between the sign support structure and the first mullion receiving element. The second device portion is slidingly receivable within the channel of the first device body portion and is characterized by a mullion receiving element for tensioned engagement with a second lateral mullion surface of opposingly paired lateral mullion surfaces adjacent the mullion face. The tensioner is operable to draw the mullion receiving element of the second body portion towards the second mullion receiving element of the first body portion.
摘要:
A process for preparing a starch-containing biomass particle stream having a significant percentage of fiber for processing into ethanol comprises the first step of: mixing the particle stream with a liquid solvent to dissolve at least a portion of the starch in the carbohydrate particle stream to form a carbohydrate slurry stream containing starch dissolved in the liquid solvent. This first step removes a portion of the fiber from the carbohydrate slurry stream. In a second step, the carbohydrate slurry stream is held in a settling tank to remove a further portion of the fiber. An enhancement to the process is suitable for use with shell corn or other biomass having an oil-containing germ portion and a non-germ portion comprising mainly carbohydrates and fiber. This enhancement includes the step of grinding the corn to particles of a size suitable for separating the germ particles from the non-germ particles. The germ particles are processed first to remove the oil and then to remove the carbohydrates.
