Abstract: ABSTRACT    A method of producing a package is provided wherein a product is brought into a depression formed using a shrinkable sheet material, a cover is brought over the depression, the sheet material is shrunk by heating and the depression is closed with a cover by heat-sealing. In order to shrink the depression free from creases onto different and irregular product surfaces steam is admitted to the sheet material having a saturation temperature above the sheet material temperature such that the steam condensing at the sheet material transfers its heat of condensation to the sheet material.   The apparatus for performing the method comprises a sealing station with an upper tool and a lower tool movable relatively thereto and having a chamber for receiving the depression, the chamber being connected with a steam generator.

Abstract: ABSTRACT Tissue comprising a matrix of nonwoven fibers having a basis weight generally in the range of about 25 to 50 gsm. The matrix is a meltblown web having incorporated therein staple  fibers.   The combination provides  highly-improved tissue  properties  as  well  as  strength  and absorbency required for many tissue applications.  The tissues may be formed  by  a  conventional  meltblowing  process  involving extrusion of a thermoplastic polymer as a filament in air streams which draw and attenuate the  filaments to  fine fibers,  having  an  average  diameter  of  up  to  about  10 microns.  The staple fibers may be added to the air stream, and the  turbulence produced where  the  air  streams meet results in a uniform integration of the staple fibers into the meltblown web.  The matrix may contain from about 30 to about  80  weight  percent  polymer  and  have  a  subjective softness rating of at least about 10.

Title: In-tank fuel reservoir and filter diaphragm
Inventor: TUCKEY CHARLES H
IPC: B60K15/077
Filed: 1987-04-14
Granted: 1991-01-02
Abstract: ABSTRACT OF THE DISCLOSURE          A fuel system for automotive vehicles including a main liquid fuel tank which has a vertical fuel canister within the tank containing an electrically powered fuel pump.   The canister has an open bottom positioned at the bottom of the fuel tank.  The pump delivers liquid fuel from an inlet at the bottom of the canister to the engine and a pressure regulator in the line diverts fuel above the required volume back to the top of the canister which has an overflow to the main tank.          The canister, which serves as a fuel reservoir, has a bottom septum closed by a movable valve.  A filter material extends over the bottom of the canister to filter fuel entering the pump inlet.  The filter is mechanically associated centrally with a spring biased lever connected to the movable valve.          Under conditions where the bottom of the canister is starved of liquid fuel, the filter acts as a diaphragm to shift the lever against the resilient bias and open the valve to admit reservoir fuel from the canister to the pump inlet.

Title: Balanced exhalation valve for use in a closed loop breathing system
Inventor: MOELLERS CHRIS M
IPC: A62B7/10
Filed: 1988-05-31
Granted: 1991-03-12
Abstract: ABSTRACT OF THE DISCLOSURE          A closed loop breathing system includes a face mask, a pressurized bottle of oxygen-rich breathing gas, and an exhalation hose and an inhalation hose both coupled to the face mask.  Flexible breathing bags smoothen the flow of expired gas through the system, and a container of sorbent material removes CO2 from the expired gas.  A mixing valve mixes expired breathing gas from the face mask with oxygen-rich breathing gas from the pressurized container.  A balanced exhalation valve assembly coupled to the exhalation hose includes a main valve which passes the flow of expired gas from the exhalation hose into a chamber and prevents the reverse flow of gas from the chamber into the exhalation hose.  A flexible diaphragm forms one wall of the chamber and is coupled to the main valve by a rigid spacer to prevent a pressure increase in the chamber from increasing the force necessary to open the main valve.
