Abstract: An thickening system for laundry products incorporates low levels of a fluorescent whitening agent or dye, a surfactant and an acidic pH adjusting agent.  At the acidic pH, the fluorescent whitening agent precipitates as a colloidal particle, and is stabilized by associating with the surfactant, resulting in thickening. Optionally, a C6-18 soap synergistically increases viscosity.  The thickening system may be formulated with a bleaching product and preferably  with a peroxide bleach product.
Patent CA-1278737-C (CA)
Inventor: AIZAWA TADASHI
IPC: B27D1/04
Filed: 1987-06-30
Granted: 1991-01-08
Abstract: ABSTRACT OF THE DISCLOSURE      A method for assembling veneer sheet into a plywood comprising the steps of supplying the veneer sheets to a feed conveyer, stopping the veneer sheet so that the forward edge thereof is precisely oriented in the transverse direction perpendicular to the feed direction, detecting the position of the veneer sheet in the transverse direction and calculating deviation thereof from a reference line extending along the feed direction by a computor, and transporting the veneer sheet by a transfer unit to a position on an assembling conveyer for fabricating a stepped lamination.  The assembling conveyer extends parallel to the feed conveyer and is operated intermittently.  The transfer unit includes a holding member for holding the veneer sheet during the transportation and is controlled by the computor for correcting the deviation while transporting the veneer sheet.

Title: Vacuum-breaking valve for pressurized fluid lines
Inventor: PERROTT CHARLES H
IPC: E03C1/10
Filed: 1987-07-22
Granted: 1991-01-15
Abstract: Abstract For use in pressurized fluid lines, an anti-siphon and back-flow prevention valve.  A conduit is tapped into the line upstream of an outlet terminating in a bell-shaped housing.  The housing receives check valve means arranged for insuring that fluid does not escape during normal operation of the line, but for admitting vacuum-breaking air in the event of line pressure loss.

Title: Carriage latch for a disc drive
Inventor: WIENS JOHN P
IPC: G11B5/54
Filed: 1987-08-28
Granted: 1991-06-18
Abstract: ABSTRACT OF THE DISCLOSURE            A dynamic lock for a disc drive carriage incorporates a plunger that captures an extension on the carriage. The plunger is guided by a solenoid and frame. The plunger is spring loaded such that it nor-mally is biased into the carrizge to restrain the carriage in the home locking position. The solenoid can withdraw the plunger and allow release of the carriage. A counterweight rotates about a pivot provided on the frame adjacent the plunger. A finger that pro-trudes from the counterweight rides in a recess on the plunger. In the event of a sudden shock to the disc drive, the shock force is transmitted from the plunger through the finger to the counter-weight. The counterweight is designed to be of equal mass to the plunger, whereby the shock force is neutralized, preventing the plunger from moving back toward the solenoid and releasing the carriage.

Title: Process for reducing the density of an extruded foam board of a thermoplastic resin
Inventor: VO CHAU V
IPC: B29L7/00
Filed: 1987-10-01
Granted: 1991-11-26
Abstract: ABSTRACT     Process for reducing the density of an extruded foam board of a thermoplastic resin The density of an extruded foam board (32) of a thermo-plastic resin which board has a thickness of 1 cm or more is reduced by exposing the foam board simultaneously or in sequence to heated air and steam.            The density reduction can be carried out in an expansion device (11) which comprises at least one chamber 12 in which simultaneously an atmosphere of steam and heated air is maintained.            The chamber (12) is provided with a steam inlet port (14) which is in communication with a steam source (16) and with an air inlet port (18) which is in communication with an air source (20).            The invention allows to control the density reduction of a foam material without influencing the supply of the installation and under atmosphere pressure.

Abstract: Abstract of the Disclosure A cutting tool having elongate cutter arms mounted about a pivot pin for outward swinging movement.  Cutting blades are mounted on the lower ends of the cutter arms and have a plurality of closely fitting hard carbide cutting elements of a predetermined shape and size secured thereto in a closely fitting predetermined pattern.  The cutting elements have parallel rear and front faces connected by a peripheral side surface extending perpendicularly to the parallel faces.  Several embodiments of pivotally mounted cutter arms are illustrated including various blades having a plurality of closely fitting cutting elements arranged thereon in a plurality of longitudinally and transversely extending rows for forming the leading cutting surface.

Title: Tap connector
Inventor: HALL GADDIS G
IPC: H01R4/44
Filed: 1987-10-28
Granted: 1992-01-14
Abstract: Abstract of the Disclosure A three part connector for use in connecting tap lines to energized main lines uses a plurality of fasteners to secure a tap line keeper and cap member to a body member.          The fasteners are peened to prevent their inadvertent removal from the connector, thus facilitating the use of the connector.          The tap line keeper may be independently used to secure the tap line to the connector to prevent unexpected tap line dis-connection during the tapping process.
