Inventor: KAWAKAMI YOSHIHIKO
IPC: B65D17/34
Filed: 1987-08-07
Granted: 1991-06-04
Abstract: ABSTRACT OF THE DISCLOSURE       A can comprising a barrel,  an upper lid and a lower lid bonded to the barrel.  Both the upper and lower lids  comprise  a  gas  liquid  impermeable  barrier  layer, preferably aluminum foil, and resin layers heat fused to both sides thereof.  Another resin layer is bonded to the exterior of the lids, with the upper lids having a tab and score to be perforated by the tab built into the resin layer.  According to the invention, the yield strength of the top lid is made greater than that of the lower lid to prevent breaking of the score if the can is dropped.  The differential strength may be accomplished by making the barrier layer of the top lid greater than that of the bottom lid.

Title: Method and products for sizing paper and similar materials
Inventor: TIEDEMAN GEORGE T
IPC: D21H17/33
Filed: 1987-09-04
Granted: 1991-02-05
Abstract: METHOD AND PRODUCTS FOR SIZING PAPER AND SIMILAR MATERIALS                   ABSTRACT OF THE DISCLOSURE The invention is a method of sizing paper and, in particular, paper made under neutral to alkaline conditions at least as high as 10.5. The papermaking stock is first treated with a polycationic material to provide sizing receptive sites uniformly distributed over the fiber surface. The presence of the anchoring points is critical to the later redistribution of the sizing material in the dryer section of the paper machine. The sizing material is then added to the slurry. This is then brought down onto the fibers by addition of a small amount of a size precipitant such as alum. The sizing molecule should have a hydrophilic portion with two hetero atoms forming a bidentate analog structure. This must have a pK in water of 6.0 or higher and a vapor pressure preferably at least 0.0006 mm Hg at 60°C. The polycationic material provides anchoring/orienting sites on the fiber to which the small globules of sizing attach when the emulsion is broken by the precipitant. Sizing will develop in the dryer section of the paper machine, presumably by vapor phase redistribution of sizing from the attached globules to unfilled sites where an anchoring point is present. Alkyl and alkenyl substituted catechols, beta-diones, hydroxamic acids and imides are among the new classes of sizing materials disclosed.

Inventor: SARGEANT ROBERT B
IPC: G01N33/558
Filed: 1988-05-30
Granted: 1993-02-16
Abstract: Abstract A method and apparatus for conducting specific binding pair assays, such as immunoassays, is described. A porous membrane capable of non-bibulous lateral flow is used as assay substrate; a member of the binding pair is affixed in an indicator zone defined in the substrate. The sample is applied at a position distant from the indi-cator zone and permitted to flow laterally through the zone; any analyte in the sample is complexed by the af-fixed specific binding member, and detected.  A novel method of detection employs entrapment of observable particle in the complex.  Blood is a particularly pre-ferred sample as the red blood cells can be used as the observable particles for detection of the complex.

Abstract: ELECTRICAL PANEL ASSEMBLY      David C. Kamp Albert P. Newman ABSTRACT OF THE DISCLOSURE   An electrical panel assembly providing a plurality of receptacles for use with cable connectors.  The connectors and receptacles are of the known type having single contacts which lock together when the connector is mated with the receptacle and rotated a partial revolution with respect thereto.  The panel assembly comprises a front panel element with from two to five receptacles arranged in a side-by-side row therebehind. The front panel element has an opening therein for each receptacle through which a cable connector can extend for mating with the receptacle.  Polarizing devices are provided in association with each receptacle and each cable connector to assure that each cable connector can be mated only with its respective receptacle.  Each panel opening, except the first, is provided with a locking mechanism shiftable between a normal locking position wherein it blocks entrance of a connector into its respective panel element opening and a retracted position permitting entrance of a connector into its respective panel opening.  The locking mechanism for each opening is shifted to its retracted position when the appropriate connector is inserted through the preceding opening and mated and locked with its receptacle.  Each locking mechanism in retracted position precludes removal of the connector from the preceding opening.  As a result of this, the connectors must be connected to their respective receptacles in a given order and disconnected therefrom in the reverse of that order.
