Abstract: A video distribution system transmits selected video programs to a number of independently controlled video monitors. The video monitors are arranged in groups, each group being coupled to a distinct transmission medium. A program selector associated with each video monitor generates video connection requests which specify a video source to be connected to that video monitor. A two stage video switch apparatus couples specified video sources to specified video monitors. The first stage routes specified video signals from the video sources to the second stage, which is a frequency multiplexer. The frequency multiplexer then transmits the specified video signals for each group of video monitors in distinct frequency bands on one of the transmission mediums. Each video monitor within each group of monitors has a tuner that is tuned to receive the video signal in a distinct one of the frequency bands. In effect, the transmission medium for each group of video monitors has a separate transmission channel for each of the monitors in the group. Finally, the system has a controller which receives the video connection requests, and controls the video switch apparatus so that it couples specified video sources to specified video monitors.

Abstract: A process for producing bread dough in a very short time, which comprises the first step of kneading 40 to 80 parts by weight of flour, 30 to 80 parts by weight of water, provided that the amount of water does not exceed that of flour, and a suitable amount of yeast to such an extent that the weakening of dough begins within 5 minutes as determined by the resistograph of the mixture, and the second step of adding to the mixture, immediately or after leaving the mixture as such to cause fermentation, such an amount of flour that the total amount thereof will reach 100 parts by weight and, if necessary, a suitable amount of water to continue kneading. When an acid is added in the first step to regulate the pH of the kneaded mixture to 4 to 5 and a salt is added in the second step to regulate the pH of the kneaded dough to 5 to 6, the obtained dough has excellent elasticity and the bread produced therefrom has a high mechanical strength. When a reducing agent, amylase, emulsifier or oxidizing agent is added in the first or second step, the obtained dough has improved properties.

Abstract: A press-on closure 10 for a tubular container 12. The closure includes a molded plastic frame 14 having a ledge 28 on which an end panel 16 is seated and to which the end panel is peelably secured. The end panel has a free outer peripheral edge unbonded to the frame. The resultant closed container is subject to retorting with the result that heretofore the end panel could axially outwardly deform and possibly initiate internal peeling. To prevent this peeling, the frame is provided with a thin flexible integral flange 36 forming a continuation of the ledge on which the end panel is seated. The end panel is also peelably bonded to the flange and the flange deforms or deflects with the end panel. The frame has a press fit onto the container, which is preferably in the form of a metal can, which at the end thereof to be closed by the closure is provided with a radially outwardly directed curl 48. The curl terminates in a raw edge 54 and is so shaped that when it is seated within a groove in the underside of the frame, the raw edge is embedded in a skirt portion of the frame to permanently and sealingly lock the curl within the frame.

Abstract: In order to simplify the programming structure and facilitate testing of that structure, the programmable elements in a cellular programmable logic integrated circuit (such as a field programmable gate array ("FPGA") or a programmable logic device ("PLD")) are connected in one or more series with switches interposed between the elements in the series. Initially, all of the switches in each series are enabled so that the ability of the series to correctly pass data can be tested. Thereafter, the switches are progressively disabled, starting from the switch which is most remote from the data source, so that data is stored in successive programmable elements, again starting with the programmable element which is most remote from the data source.

Article fabrication mechanisms are mounted to project from the panels. Operating means are disposed within the modules and are operatively engaged through the panels with the fabrication mechanisms. An operating and control system is provided for a machine in which disposable absorbent articles are fabricated. Continuously operating mechanisms are driven by electric motors for continuously operating on moving webs and other components of the article. A main drive shaft is rotated for transferring power through direction phasing mechanical power transfer devices to mechanisms which intermittently effect unity operations with respect to an associated moving web. The direction phasing mechanical power transfer devices are controlled relative to a sensed portion of an article component so as to temporarily vary the speed of the unity operation and effect registration of the operation in a preselected relationship with the associated moving web. <IMAGE>   <IMAGE>
