Title: Method for producing a grain- oriented electrical steel sheet having a high magnetic flux density
Inventor: SUGA YOZO
IPC: C22C38/02
Filed: 1983-09-20
Abstract: A feature of the present invention is to set S</=0.007%, Mn=0.08 SIMILAR 0.45%, P=0.015 SIMILAR 0.45% in a slab. The present inventive idea does away with the conventional concept of using MnS as an inhibitor and prevents incomplete secondary recrystallization by the S content, which is decreased to a level as low as possible. In addition appropriate amounts of Mn and P are added. Due to these advantages, a high Si content, which leads to a watt loss reduction, can be employed in the present invention. In addition, the temperature of slab heating can be drastically decreased as compared with the prior art. The watt loss of a product produced by a low- temperature slab-heating is considerably lower than a product produced by a high-temperature slab- heating. After hot-rolling, the material is annealed at 850-1200 DEG C and then cold-rolled with a reduction of 180%. The invention may particularly be applied to continuously cast slab.

Title: Converting rotary motion to linear motion eg cam rotation to valve reciprocation
Inventor: STIDWORTHY FREDERICK MICHAEL
IPC: F16H25/08
Filed: 1985-12-12
Abstract: An arrangement for converting rotary motion of a cam (9) on a camshaft (1) into periodic linear movement of a poppet valve (8) guided for linear movement by a guide (7). The valve has a bucket (5) acted upon by a valve spring (not shown) and provided with a tapered shoe (4) presenting a curved contact surface. A cam follower (3) is pivotally mounted on a pivot (2) defining a pivot axis parallel to the axis of rotation of the camshaft (11).
