An oval cooling tube for the central portion of a fiberizing bushing having a plurality of parallel cooling fins attached to the sides thereof.

A system and method of supporting pause-resume in a video-on-demand service of a type which can accommodate multiple viewers sharing a common data stream is described. When a video server receives a performance request from one of the viewers for showing a particular video, it identifies and reserves a look-ahead stream. The look-ahead stream is another video stream which is scheduled to become available after a predetermined time period. When the video is commenced, a common data stream for the...

A metal blank or tin plate is drawn to form a cup, said cup is then subjected to ironing, trimming and flanging to produce a metallic container or can. However the final ironing is not effected at all on the upper part of the can body wall. For this purpose, a punch core is used which has the upper portion of smaller diameter and the rest portion of larger diameter, the latter constituting a substantial part of the core. The container thus produced has a thin walled center portion constituting a...

A composition of matter comprising vinyl ended copolymer chains having a number average molecular weight (M.sub.n) of about 1500 to 75,000, the number average molecular weight being determined by gel permeation chromatography (GPC) at 145.degree. C., a ratio of vinyl groups to total olefin groups according to the formula ##EQU1## where a and b have the following sets of valuer: when a=-0.24, b=0.8; when a=-0.20, b=0.8; when a=-0.18, b=0.83; when a=-0.15, b=0.83; and when a=-0.10, b=0.85; and whe...

The invention relates to a process for controlling the flow of information exchanged between at least one station for transmitting interactive programs and a plurality of interactive terminals. According to the invention, during each interactive program, each terminal is sent a group of data intended to set up a protocol for establishing interactive communications between said transmission station and said terminals.

A system and method for distributing real-time, compressed, digital video data from a video library composed of multiple mass storage devices through a digital video data server to large numbers of viewers via distribution networks is provided. The server obtains selected frames of video data for viewer-requested programs from high-speed memory using a buffering strategy, replicates the data via a multi-cast technique for each viewer listed in an assigned synchronization group and forwards the d...

An on-demand communication system provides a multimedia server connected to a plurality of clients via a network. A data stream can be transmitted in response to a transmission request of a title from a transmission device at the site of the client. The transmission device will transmit a set of reproduction information, including a plurality of titles and reproduction start times to the server along with the client identification. The server contemporarily would store, in a buffer, the reproduc...

A method for forming a container in a reduced number of steps and a container made therefrom which has a thin upper wall section and a heavier lower wall section and bottom to provide extra resistance to impacts in the more normally vulnerable areas of the container, the method also comprehending forming a container from a wall ironed cup and leaving a flange on the open top of the container thus eliminating a common problem of split flanges and also simplifying the trimming operation by a simpl...

This application discloses a novel process in the manufacture of two-piece metal cans and the like wherein a predrawn cup is produced at the mill rather than by the can manufacturer. The predrawn cup is flanged and tapered. The predrawn cups are stacked in nested relation and a plurality of stacks are packaged at the mill for shipment to the can manufacturer. The can manufacturer then need only redraw and wall-iron the cups and trim, flange, wash and decorate them in order to complete the manufa...

In a clamping device which serves to connect two profile section parts, in particular a horizontal beam (2), to a vertical support (1), an axially movable, spring-loaded retaining pin (7) is located at the end of one profile section part (2). The T-shaped head (8) of the retaining pin (7) engages behind a longitudinal groove (16) of the other profile section part. By means of a screw (12), which is eccentrically supported and engages in a conical recess (10) of the retaining pin (7), the retaini...
