Abstract: A solid crystalline phosphoric acid catalyst comprising crystallites of both silicon orthophosphate and silicon pyrophosphate and having a total X-ray intensity of at least 30 percent relative to alpha-alumina is disclosed. The solid crystalline phosphoric acid catalyst is produced by crystallizing an amorphous mixture of an acid oxide of phosphorus and a siliceous material at a temperature of from 250 to 450°C and in the presence of from 3 to 50 mole percent water vapor based upon the total vapor rate to the crystallizing step. The catalyst is particularly useful in extending the life of a hydrocarbon conversion reaction such as olefin polymerization before catalyst replacement or regeneration becomes necessary.

Abstract: An image scanning apparatus comprises a simple document feed mechanism. An image sensing unit including a light source and an image sensor is reciprocally moved between a home position and a scan starting position. The document feed mechanism is mechanically connected to the image sensing unit and moved along with the sensing unit. The document feed mechanism includes a frictional roller which contacts with a glass platen, on which an image bearing surface is faced down, and is coupled to a shaft through a one-way clutch. The one-way clutch inhibits the rotation of the roller during the movement from the home position to the scan starting position and allows the rotation during the movement from the scan starting position to the home position. At the home position, the leading edge of the document is inserted by an operator between the frictional roller and the glass platen. The document is fed or moved by the friction of the roller from the home position to the scan starting position. During the movement from the scan starting position to the home position, the roller is freely rotation on the document.
