Title: Film transfer molding
Inventor: WEAVER WILLIAM R
IPC: B29C70/76
Filed: 1989-07-14
Granted: 1993-10-12
Abstract: ABSTRACT Producing an encapsulated glazing unit having a weather-stable film on an exposed surface of the gasket.  There is provided a two-part mold whose sections cooperate to define a mold cavity for receiving the peripheral margins of the transparent glazing unit upon which the gasket is to be formed.  A sheet of the weather-stable film is positioned over the mold section having the portion of the cavity which defines the surface to which the film is to be applied.  With the mold closed, a flowable gasket forming material is injected into the mold cavity behind the film to deform the film into conformity with the mold surface.  As the gasket cures in situ, the film chemically bonds to its surface.  The encapsulated unit is removed from the mold and the excess film is trimmed from around the gasket.

Title: Compact tampon applicator with improved interlock
Inventor: TARR WARREN T JR
IPC: A61F13/32
Filed: 1989-07-17
Granted: 1994-04-05
Abstract: ABSTRACT OF THE DISCLOSURE    A shortened tampon applicator of the telescoping tube type employs an ejector tube to store a tampon at its distal end and an outer tube disposed by a slip fit thereover.          Directionally-locking inward flaps fixed within the distal end of said outer tube engage the distal end of the tampon stored in the ejector tube thus securing the latter relative to said outer tube while permitting only distal expulsion therefrom.  The ejector tube advantageously has inwardly biased short stubby fingers at its distal end which catch behind the proximal end of the tampon.  Preferably, the applicator tubes are both molded from soft plastic and have an improved restraining means for interlocking the two tubes.  This means comprises a stopping ring and a shorter adjacent inner stabilizing ring positioned to project from the inner surface of the outer tube at its proximal end and an axially overlapping a third ring of ribs positioned around the outer surface of the ejector tube near its distal end.  The positioning and shape of the stabilizing third ring relative to the other two rings serve to decrease wobble and to increase the tube interlock strength, among other advantages.

Title: Method for preparing light polarizer
Inventor: LAND EDWIN H
IPC: B29K29/00
Filed: 1989-07-19
Granted: 1993-10-05
Abstract: ABSTRACT OF THE DISCLOSURE A stainable polymeric sheet material adapted to the production of a light polarizer therefrom is provided by a method, according to which, a support sheet of amorphous polymeric material is uniaxially stretched in a first direction (at or above the glass transition temperature of the polymeric support material), a layer of polyvinyl alcohol (PVA) is coated from an aqueous PVA-containing composition onto the uniaxially stretched support material, and the PVA-coated uniaxially stretched polymeric sheet material is stretched along a second direction, at an angle within about ? 60 degrees to a normal to the first direction of stretch.  The method provides a material which can be converted, by incorporation of visible dichroism into the PVA layer, to a light polarizer which combines efficient light polarizing properties and good mechanical strength and resistance to fracture along the stretch directions.

Abstract: CONTINUOUS MOTION PACKAGE FORMING MACHINE                  ABSTRACT              A continuous  motion packaging machine which forms packages from overlying webs advanced along a path at a constant speed. A tooling carriage traverses a repetitive path which includes an "on-line" increment during which the tooling carriage matches web movement and package operations are performed.  The tooling carriage is driven by linkage including a power input shaft operated by varying speeds throughout each cycle to maintain carriage position relative to the webs.  Two brushless servo motors are used.  One drives the webs, the other drives the tooling carriage.  A computer program compares relative motor positions at points throughout each cycle to a pre-established position pattern and adjusts motor controller output to maintain one motor position relative to the sensed position of the other motor.

Abstract: An elastomeric strip of substantially U-shaped cross-section is disclosed which is adapted to be mounted on a flange having longitudinally-spaced curved sections. The elastomeric strip includes a support frame having longitudinally displaceable frame portions that are reinforced with longitudinally extending degradable reinforcing material. The reinforced support frame is advanced through an extrusion die where a coating of an elastomeric material is extruded on the support frame to form an elastomeric strip without degrading the degradable material. Longitudinally-spaced regions of the degradable reinforcing material corresponding to the longitudinally-spaced curved sections of the flange are then degraded, allowing the elastomeric strip to more faithfully follow the curved sections of the flange when the strip is mounted thereon.

Abstract: ABSTRACT      A thermal beverage container and a lid therefor are provided.  The container includes an insulated reservoir for storing and dispensing liquid.  A spout is located at the base of the container and is in communication with the reservoir.   A dispensing arm is operable to open a valve upon actuation thereof to permit liquid to be expressed from the reservoir via the spout.   The container has an open upper end onto which a lid is threadably secured.  The open upper end of the container defines a neck of reduced diameter relative to the reservoir.   The neck has a groove formed therein which extends from the reservoir to the upper surface of the container.   The lid is complementary in shape to the opening in the container and thus, includes a plug for seating in the neck.  However, the groove is not filled by the plug.  A funnel-shaped, centrally located passage is formed through the lid and supports a floatable ball. The passage permits  liquid to be poured  into the insulated reservoir without removal of the lid.  A vent hole radially displaced from the passage is also formed through the lid and communicates with the groove to improve air flow from the reservoir to the exterior of the container upon the pouring of fluid therein.
