Patent CA-2052945-A1 (CA)
Title: Powered clamp with parallel jaws
Inventor: SAWDON EDWIN G
IPC: B23Q3/06
Filed: 1991-10-08
Abstract: ABSTRACT An improved clamping mechanism for removably clamping an object having at least two jaws that clampingly engage surfaces upon the object. This clamping mechanism utilizes a housing that has a chamber and a plurality of passages that lead radially from the chamber through the housing walls. A camming member is disposed within the chamber and is engaged with a plurality of follower members that are partially disposed within the radial passages. An actuating means actuates this camming member axially within the chamber to cam the follower members radially inward or outward, thereby radially displacing the jaws which are attached to the follower members. Since the follower members are shaped to correspond with the radial passages, the follower members slidingly engage with the radial passages. This engagement between the follower members and the passage walls restricts the displacement of the follower members, and thus the jaws, to purely translational displacement, radially inward and outward.

Title: Process for regulating the hot metal refining operation
Inventor: MOUSEL ROBERT
IPC: C21C5/30
Filed: 1991-12-05
Abstract: A B S T R A C T            The invention concerns a process for controlling the operation of the refining of hot metal  in a steelmaking converter by  blowing from above at least two supersonic primary oxygen jets of a given total flow rate against  the surface of the  bath to be  refined. This process is characterized in that the aimed at ratio  between the decarburization speed of the metal and the oxidation speed of the slag is achieved by the fact that each one of the jets coming out of a non rotating lance impinges within the same annular area of on the  bath with a  given energy. Depending  on the  physico-chemical condition of the bath, the impact energy of the jets  is varied between upper and lower  limits, whereas at the same  time the height of the  lance above the surface  of the bath  together with the total  volume of the  oxygen flow feeding  the bath  are both kept at a practically steady level.      Figure 1.

Title: Transducer carrier for disk file and liquid film head-disk interface
Inventor: ALBRECHT THOMAS R
IPC: G11B25/04
Filed: 1992-04-29
Abstract: A  disk  file  with  substantially  reduced  head-disk spacing   and   corresponding   improvement   in   recording performance uses a disk coated with a film of conventional high  viscosity  lubricant,   a  lubricant  reservoir  for replenishing the lubricant on the disk over the life of the file, and a transducer carrier with feet which ski on the high viscosity liquid film.  The file does not include any means for recirculating the lubricant since the lubricant spins off the disk at a relatively low rate due to its high viscosity.   The lubricant reservoir contains a very small amount of lubricant and thus may be maintained inside the substantially sealed disk file.   In one embodiment of the invention,  the sealed disk file is essentially evacuated. The operation of the disk file in a near vacuum environment is possible because, unlike conventional disk files, air is not required to support an air-bearing head-disk interface and the high vapor pressure of the relatively high molecular weight lubricant prevents its evaporation.
Patent CA-2070977-A1 (CA)
Inventor: BECKER WOLFGANG

Title: Device for guiding a transversely stable web
Inventor: NIEMANN HEINRICH
IPC: B65H23/02
Filed: 1992-06-16
Abstract: For guiding webs of paper or cardboard, a guide cylinder extending across half of the web grips onto the surface of the web and achieves moving corrections on the webs by rotation or swinging.  The long, linear support zone of the guide cylinder causes a high mechanical stress, whereby the guide cylinder exerts almost no corrective effect in its center zone.  By dividing the guide cylinder into at least two spaced-apart, parallel guide rolls having their axes disposed perpendicular to the running direction of the material web, a suitable larger effective area is obtained for correction of the direction of movement.

Abstract: An improved method of serging a trouser-fly piece on a serging machine having a trimming cutter is disclosed wherein a continuous trouser-fly blank assembly is fed intermittently into a first feed path extending toward the movement of the trouser-fly piece being advanced by the serging unit. Then the continuous trouser-fly blank assembly is cut into a succession of elongate rectangular trouser-fly pieces each of which is subsequently advanced toward the serging unit along the first feed path. Thereafter, at least a corner of a leading end of the trouser-fly piece is trimmed by the trimming cutter and, substantially at the same time, one curved longitudinal edge of the trouser-fly piece including the trimmed corner is serged with a serge stitching. In this instance, the trouser-fly piece is caused to turn in one direction to move from the first feed path in a second feed path extending parallel to and aligned with the path of movement of the trouser-fly piece being advanced by the serging unit. With this rotational movement of the trouser-fly piece, the trimming cutter accurately traced a substantially arcuate trimming line passing across the corner. The serged trouser-fly piece is automatically discharged from the serging unit.
