Title: Process for making paper using a substituted succinic anhydride as a sizing agent
Inventor: YOSHIOKA SHIGEHIKO
IPC: D21H17/28
Filed: 1987-07-21
Granted: 1991-01-29
Abstract: ABSTRACT OF THE DISCLOSURE        A process for making paper using a substituted succinic anhydride as a sizing agent which has the steps of preparing pulp slurry containing (a) an aqueous dispersion of a substituted succinic anhydride in which a cationic tapioca starch containing at least 0.3 percent by weight of basic nitrogen is added and mixed, and (b) a colloidal silica, and forming a paper sheet to improve the retentions of a fine fiber and a filler in the pulp slurry in the sheet forming step and to largely suppress the operation of decreasing the sizing performance of the substituted succinic anhydride with the colloidal silica (b) added as the retention aid, thereby preparing sheet paper having excellent sizing effect.  Thus, the process for making paper can not only remarkably reduce the sizing cost but can also efficiently utilize the fine fiber and the filler in the pulp slurry.

Title: Unloading flap for pourable particulate material
Inventor: ZEHNDER JUERG
IPC: B60P1/56
Filed: 1987-09-21
Granted: 1992-11-10
Abstract: ABSTRACT           An unloading flap of a stationary or mobile silo for pourable particulate material having at least one outlet opening comprises an upper part that is secured to a first silo wall and a lower part that hinges on the upper part and can be tilted into the open and closed positions by means of an actuating rod that can be power driven; the lower edge of the straight or angled lower part with respect to the upper part is in the form of a projecting support; in the closed position  this  support  rests  along  a  line  or  area  on  a longitudinal groove in the region of the lower edge of a second silo wall; a device attached to one of the two parts of the flap exercises a moment of rotation on the other part of the flap such that the angle (.alpha.) between the upper and lower parts is reduced to an angle (.alpha.') in the open position to such an extent that during the closing operation the projecting supporting  edge  can  be  introduced  into  the longitudinal groove by the actuating rod acting exclusively on the upper part of the flap.

Title: Magnetoresistive sensor
Inventor: MOWRY GREG S
IPC: G11B5/265
Filed: 1987-10-26
Granted: 1992-05-19
Abstract: ABSTRACT OF THE DISCLOSURE     A magnetoresistive head having separate write and read gaps including a leading write pole, a trailing write/shield pole, and a following shield pole, wherein an elongated magnetoresistive sensor strip having a central sense region is mounted in the read gap, and further wherein the leading write pole has a length corresponding to the central sense region of the sensor and defines a track width, end the trailing/shield pole and following shield are the same length as the overall length of the magnetoresistive sensor strip.
