Abstract: ABSTRACT OF THE DISCLOSURE       A carpet and pad installation avoids the need for stretching and tackless strips by utilizing a pad with pressure-sensitive adhesive on its one surface.  The pad is first laid on the floor surface and trimmed as required, with either the adhesive surface down to adhere to the floor, or with the adhesive surface up and another adhesive applied to the floor prior to laying the pad.  A removable release film may cover the pressure-sensitive adhesive on the pad, so that with the adhesive side up the carpet may be unrolled over the release film and then cut and seamed as required.  The seamed carpet is folded back and the release film is removed from the exposed area of the carpet cushion, then the carpet is pressed down onto the exposed area of adhesive.  Then another portion of the carpet is folded back, the release film is removed from that area, and that portion of the carpet is pressed onto the exposed pressure-sensitive adhesive of the carpet cushion.  If the adhesive side of the pad is against the floor, a similar procedure is followed, with adhesive being applied to the pad's upper surface after the carpet has been trimmed.

Abstract: ABSTRACT      An improved cast cylinder head for a high performance interns combustion engine is provided by an especially con-figured quench surface  from which a contoured combustion chamber extends having a metal mass buildup shrouding the exhaust gases through the exhaust valve seat. A metal mass buildup configuration  is  also  provided  about  the  intake valve seat which acts in conjunction with an especially con-figured and proportioned valve intake passage to draw the fuel-air  mixture  into  the  combustion  chamber  in  an unshrouded,  helical  flow pattern.   The  intake passageway configuration is such that a rich fuel-air mixture is drawn through the intake valve seat at a portion thereof remote from said exhaust valve seat while a lean fuel-air mixture exits the intake valve seat adjacent the exhaust valve seat. Positioning the fuel-air mixture in such a manner in combi-nation with  the unshrouded metal  mass  buildup minimizes short-circuiting of the fuel through the exhaust valve seat in a valve overlap condition.

Title: Mouth-to-mouth resuscitator device
Inventor: EISENBERG MELVIN I
IPC: A61M16/06
Filed: 1988-07-13
Granted: 1992-05-12
Abstract: ABSTRACT    A  resuscitator  device for providing a physical shield between the rescuer and a victim requiring mouth-to-mouth resuscitation, and comprising  a flexible sheet to conform to the  contour of the  face of the victim in the area around the mouth and nose. A mouth opening is  centrally formed in said sheet.   A hollow rigid tube  surrounds and  is secured to the periphery of said mouth opening  and  depends downward therefrom to an outer end,  for inserting into the mouth of the victim.  A self closing, one way valve is contained in the tube, and  includes  a  flexible,  sleeve having an air inlet open end  in communication with the mouth opening and an air outlet end  adjacent the  outer end of the tube which is normally closed from the  action of a spring strip secured to the sleeve adjacent the outlet end.  An air  tight  seal  is made with the lips of the  rescuer  and  victim separated  by the sheet functioning as a shield,  when  the  rescuer exhales  a deep breath under presssure into the inlet of the  valve.          The forced air overcomes the resilient force of the spring strip and opens  the sir outlet,  for discharging the air inside the  victim's mouth.  When  the  breath  is  fully  exhaled,   the  spring  strip resiliently  closes the air outlet to prevent any back flow of  air, mist  or  liquid from the victim to the rescuer.  The  rescuer  then moves  his lips away from the sheet to take another deep breath  and thereby breaks the seal to permit exhaling from the victim.  Grooves formed  in  the victim's side of the sheet  provide air pathways  to the  outside  and  prevent blockage of air from  the  mouth  of  the victim.  An irregular non-smooth surface is formed on an area of the sheet  to  prevent clinging of the sheet to the  nose,  which  could inhibit air flow out from the victim's nose.

Title: Fabrication of patterned lines of high t -superconductors
Inventor: GUPTA ARUNAVA
IPC: C01G3/00
Filed: 1988-08-19
Granted: 1995-05-02
Abstract: A method for producing a patterned layer of high Tc oxide superconductor is provided in which patterning is accomplished prior to the attainment of a superconducting state in the layer.  A solution containing precursor com-ponents of the desired oxide superconductor is sprayed onto a substrate and dried to pro-vide a layer thereon.  This layer is then irradiated in selected areas to convert the irradiated layers to an intermediate oxide state, the nonirradiated areas being un-changed.  The nonirradiated areas are then dissolved away, leaving a pattern of oxide material.  This oxide material is then con-verted to a high Tc superconducting state, as by annealing in an oxygen atmosphere.  This provides the patterned layer of high Tc oxide superconductor.  An example of such a super-conductor is a mixed copper oxide, such as Y1Ba2Cu3O7-x.
