Title: Container closure cap with metering appliance
Inventor: WASSILIEFF VICTOR
IPC: B65D41/26
Filed: 1987-07-06
Granted: 1992-06-02
Abstract: Abstract of the Disclosure A device for metering a fluid product comprises a closure cap threaded onto the neck of a container and acting on the stem of a valve member to lift the latter off a seat formed at the lower end of a cylindrical wall fixedly inserted into the neck of the container against the action of a resilient member. A metered dose of the product is dispensed by turning the container upside down and unscrewing the closure cap by then filled with the metered dose.          In the inverted position the fluid product contained in the container flows into a chamber defined by the cylind-rical wall via the opened valve member and a passage associated to the resilient element. The flow of the fluid product into the chamebr is stopped by the engage-ment of the valve member with its seat as the closure cap is being unscrewed. In another embodiment, an intermediate element having a screw-threaded neck portion and a seat for the valve member is secured to an annular rim of a container. A cylindrical wall formed integrally with the seat is in sealingly slid-ing engagement with a cylindrical wall formed integrally with the bottom wall of the closure cap. A tubular element formed integrally with the cylindrical wall protects the resilient element from contact with the fluid to be dis-pensed. A metered dose of the product is dispensed by turning the container upside down and unscrewing the clos-ure cap. The screw-threaded peripheral wall of the closure cap remains clean during filling and emptying the metering chamber defined by the cylindrical wall 16.

Title: Method of and apparatus for contacting running webs with steam and the like
Inventor: WINHEIM STEFAN H
IPC: D21F7/00
Filed: 1987-08-07
Granted: 1992-03-10
Abstract: ABSTRACT           Steam is blown against one side of a running web of moist fibrous material in a paper making machine through a first set of apertures in the wall of an apparatus which defines a first chamber for supplying steam to the first set of apertures, a second chamber which supplies steam to a second set of apertures upstream of the first set, and a third chamber which supplies steam to a third set of apertures downstream of the first set.  The apertures of the first set discharge jets of steam at right angles to the plane of the adjacent portion of the running web, the apertures of the second set discharge jets of steam which draws some atmospheric air toward the jets issuing from the first set of apertures, and the jets of steam issuing from the third set of apertures also draw air toward the region where the jets issuing from the first set of apertures impinge upon the web so that steam is less likely to escape from the treating zone and that each increment of the running web is contacted by a preselected quantity of steam.

Title: Pressure-sensitive tape construction incorporating resilient polymeric microspheres
Inventor: DARVELL WAYNE K
IPC: C09J7/38
Filed: 1987-08-20
Granted: 1993-01-26
Abstract: Abstract Tape products for diverse end uses are obtained by applying to a sheet backing a layer of normally tacky and pressure-sensitive adhesive (PSA) containing and completely surrounding resilient non-tacky hollow thermoplastic polymeric microspheres.  When the PSA is permanently bonded to the backing and the exposed surface has an irregular contour, a removable and repositionable product results.  When the PSA forms a continuous matrix that is strippably bonded to the backing and is 1 mm or more thick, the resultant product is a foamlike transfer tape or foam tape.  Depending on the product, the PSA can contain from about 1/5 to about 2/3% of the microspheres by volume.

Title: Microwave landing system for use on a back course approach
Inventor: CHISHOLM JOHN P
IPC: G01S1/16
Filed: 1987-10-08
Granted: 1991-05-14
Abstract: ABSTRACT       The invention provides independent guidance and monitoring integrated into an MLS landing system and a scaled-down MLS take-off or missed approach guidance system useable at small airports.  An added fixed beam precision guidance system is integrated into the MLS time sequence format.  The fixed beam guidance system is based upon the concept of using paired fixed overlapping beams, sequentially radiated by different fixed antennas (80 and 81), oriented to left and right of a prescribed guidance path.  The paired beams overlap at the prescribed guidance path in such a manner that an aircraft departing or making a missed approach on such path will intercept equal signal intensities to indicate an on-course condition. Conversely, when the aircraft is off-course to one side of the prescribed path, it will intercept a stronger signal intensity for the fixed guidance beam which is directed to that side of the prescribed path and a weaker signal intensity for the fixed beam which is directed to the other side of the prescribed path.

Abstract: ABSTRACT OF THE DISCLOSURE     A cover  for a  pickup truck bed including the features:  An anchor strip is applied to  the  front  wall  and  a  front cover panel  is  hingedly  connected  thereto.   Center and rear panels are hingedly connected together  and  a  lock  mechanism  on each panel locks  the  panels  in  the desired covered position while allowing the  individual  panels  to  be  unlocked  and pivotally opened about  the respective  hinge connections.   The hinge con-nections  permit  relative  sliding  along  the hinge  axis  for dismounting of  the cover  panels.   The panels are sealed to the truck bed  walls  and  the  hinge  connections  are  formed  by a nesting arrangement  that seals and channels water over the truck sides.  The rear panel seals against the  tailgate and  locks the tailgate against  opening.   The panels  are sized  to be readily handled by one person and are  standardized to  fit a  variety of truck bed  sizes.   The anchor strip is lengthened to accommodate different lengths  and  because  the  panels  fit  over  the side walls, different  widths are  accommodated by the panels reaching to different positions on the broad top edge  of the  side walls. The  hinge  connections  are  captured  by a resilient brace that allows the panels to break away if excessive force is applied.

Abstract: ABSTRACT OF THE DISCLOSURE        A purging air flow system for passing air over a lens      to keep it clean and free from particulate contaminants and also for providing a positive flow of air away from the lens has baffles                  which cause a flow across the lens      that is not symmetrical to avoid a dead air or stagnation zone in the center of the lens .  The air supply used for such purging is controlled adequately so the flow changes direction and particles are removed from the main flow of purge air by inertial separation prior to the time the air contacts the lens     .  Such air entrained particles might otherwise deposit on the lens     .  A flow control orifice      also may provide a secondary flow to carry the particles separated from the main flow out of the flow passageway     .

Abstract: MICRO-OPTICAL BUILDING BLOCK SYSTEM    AND METHOD OF MAKING SAME            ABSTRACT OF THE DISCLOSURE      A micro-optical building block system for optical processing of light signals and method for making the components  used  in  the  system.    The  basic  system includes  a master  substrate on which is mounted at least  one  building  block.   Typically,  there  are  a multiplicity  of  pre-defined  positions  at  which  the building blocks will mate with the master substrate. Building  blocks  can  be  positioned  adjacent to each other on the master substrate  in such a way as to allow light signals to be transferred between them. Mating relief patterns are formed on both  the master substrate  and  the  building  block  substrates,  the relief pattern  areas  on  the master  substrate being adjacent and repetitive, or alternatively,  different patterns.    The  mating  relief  patterns  enable  self alignment  of  the  building  blocks  at  predetermined positions on the master substrate.  The relief pattern on the building blocks is adapted to be employed to embody a variety of optical components as integral or constituent    parts    of    the    relief    pattern. Alternatively,  the  relief  pattern  is  used  as  a mechanical   fixture   for   optical   or   mechanical components, or both, which define the functions of the building blocks.
