Inventor: LUKKARI JORMA
IPC: B65G47/88
Filed: 1993-01-20
Abstract: This patent publication discloses a pneumatically operated roll stop particularly for paper rolls and a method for controlling said roll stop. The invention is based on the concept of providing the outlet line from the work chamber (8) of a pneumatic cylinder (17), which is connected to the stop arm of the roll stop, at that side of the cylinder actuated during the braking of the roll motion with a pulse-controlled valve (13) suitable for controlling the outlet flow rate from said work chamber (8) of the cylinder. Such a roll stop comprises a frame, at least one stop arm adapted to said frame with the help of a pivotal joint, said stop arm having a member adapted to its distal end, capable of making contact with said roll to be stopped, further two pneumatic cylinders (7a, 7b) connected by their one ends to said frame and by the other ends to said stop arm, and at least one control valve (12), connected by air lines (9, 11) to said cylinder (7), for the control of the function of the cylinder (7). The air line exiting from the work chamber (8) of the pneumatic cylinder (7) is provided with a valve (13) between the cylinder (7) and the air discharge point, said valve being capable of controlling air outflow from the line by way of pulsed open and closed operation of the valve (13). The invention offers smoother operation of the roll stop and prevents damage to the roll.

Patent CA-2108338-A1 (CA)
Inventor: HORNE CASPAR
IPC: H04N21/434
Filed: 1993-10-13
Abstract: The quality of video images received at the remote end of an ATM network capable of transmitting data at high and low priorities is greatly improved at high cell loss levels by employing a two-layered video encoding technique that adapts the method for encoding information transmitted in the low-priority digital information stream to the rate of cell loss on the network so that compression efficiency and image quality are high when the network load is low and resiliency to cell loss is high when the network load is high. The encoder adapts its encoding method in response to a cell loss information signal generated by the remote decoder by selecting the prediction mode used to encode the low-priority digital information stream, and by changing the frequency at which slice-start synchronization codes are placed within the low-priority digital information stream (FIG. 1).
