Patent CA-2243733-C (CA)
Inventor: PHILLIPS JOSEPH R
IPC: D21C7/00
Filed: 1998-07-21
Granted: 2007-01-30
Abstract: In a vertical digester for producing chemical pulp, or other vessel for treating a slurry of comminuted fibrous cellulosic material, the cost of manufacturing the shell is significantly reduced by eliminating the external step increases in the digester shell. The digester shell has a substantially constant internal diameter from just below the inlet to just above the outlet, screen assemblies being provided by an internal transition (e.g. conical) having an angle of convergence of less than 40° (e.g. about 10-25°) above each screen assembly so that the slurry flows through the transition without bridging or hang-up, and a step increase, or other increase, in diameter back to the first diameter after the screen assembly.

Title: Circuit for synchronizing picture and method therefor
Inventor: KIM SEONG-BONG
IPC: H04N21/43
Filed: 1998-08-04
Granted: 2002-12-03
Abstract: A picture decoding synchronizing circuit and a picture decoding synchronizing method are provided. When the decoding synchronization is controlled in units of a picture, in a variable length decoder using the transferred PTS and DTS information, the value obtained by adding the previous DTS to an offset is determined to be the DTS value of the current picture, if errors are generated in the transferred PTS and DTS, considering the errors of the transferred bit stream. If no errors are generated in the PTS or DTS, then the transferred PTS and DTS are determined to be the DTS value of the current picture. By controlling the picture decoding using the determined DTS value, the bit buffer does not underflow or overflow and the decoded data is displayed naturally on a screen.

Abstract: A push rod rotator and push rod boring rig uses a reciprocating carriage to push a drill string of push rods into the ground and pull the drill string back out usually with an expander and pipe or utility lines. A push rod rotator is connected to a swivel supported on the non-rotating carriage. The rotator is a two-part assembly, one part is a non-rotating conduit, having two or more helical slots and the other part has a pin which follows the slots for inducing relative rotation. Slips grip the: push rods and are reversible to enable push and pull operations. Preferably the slips trail the carriage and the rotator leads the swivel. The rotator is adapted to a boring rig having a frame, and hydraulic cylinders for reciprocating the carriage relative to the rig. The double-acting cylinders are mounted in pairs with the powerful extension stroke oriented to pull back the drill string and push rods and the weaker retraction stroke to push rods.
