Title: Closures
Inventor: GUEST JOHN H
IPC: B65D41/04
Filed: 1984-08-24
Granted: 1991-03-26
Abstract: ABSTRACT    A closure for a container comprises a top 11 with a depending skirt 12 having an internal screw thread.   Where the skirt joins the top, the internal surface 15 of the skirt is conically flared in a direction away from the top, and a flexible resilient fin 18 extends from the underside of the top substantially parallel to the flared surface 15.  The free end portion of the fin is thickened as by the provision of a broad rib 30 on the radially inner surface of the fin.   When the closure is secured on to a container, the fin 18 becomes deformed outward and is sufficiently long to extend round the outer corner portion of the top of the container and is pressed into tight sealing engagement with said outer corner portion by the flared surface.   The thickness of the free end portion of the fin causes it to resist expansion and to hug more closely to the corner portion of the top of the container.   The radially inner surface of the fin may have annular grooves therein, for example of triangular shape, to provide a ribbed surface to improve the seal.

Title: Optical pressure-sensing system

Filed: 1986-12-16
Granted: 1991-10-08
Abstract: OPTICAL PRESSURE-SENSING SYSTEM                 Abstract of the Disclosure An optical pressure-sensing system in which an optical beam splitter couples input light from a light source to an optically resonant pressure sensor and couples output light reflected from the sensor to a light detector.  The light detector may divide the output light into bands having differ-ent wavelengths and then take the ratio of the light in one band to the light in the other band in order to provide an output that is insensitive to various spurious responses in the system.  The optical beam splitter may be formed by two pairs of graded refractive index lenses.  A partially reflective, partially transmissive mirror is sandwiched between the lenses of one pair, while a dichroic mirror is sandwiched between the second pair.  The pairs of lenses are placed in abutting rela-tionship to each other.  The optical beam splitter may also be formed by a block of transparent material having a partially reflective, partially transmissive mirror on one edge.  The optical pressure sensor is formed by a transparent substrate having a cylindrical recess and a resilient diaphragm posi-tioned over the recess to form an optically resonant cavity. Differential pressure may be sensed by placing a second substrate having a cylindrical recess over the side of the diaphragm opposite from the first substrate.  The optical pressure sensor may be specifically adapted for use as a microphone by utilizing a relatively thick cavity having a pedestal projecting from the substrate close to the diaphragm to form an optically resonant cavity.  The optical pressure sensor may also sense gas density by filling the optically resonant cavity with the gas being measured having a pressure at a predetermined density and temperature that matches the pressure of the gas being measured at that same density and temperature.
