Abstract: ABSTRACT OF THE DISCLOSURE      The valve includes a valve body formed onto a lid of a container, a closure member which is located in the valve body and a spiral spring which presses the closure member into the valve body so as to keep the valve closed.  A first sealing section is formed on a section of the closure member and cooperates with a valve seat in the valve body.  A second sealing section is formed on the valve body and cooperates with a part of a spray gun or similar device, into which the valve body section is inserted in order to prevent a leaking or fluid at that point.  The valve does not need any sealing members made of elastomeric materials or rubber.  In this way, deterioration of such sealing members, which is caused by the fluid and leads to loss of sealing capability, is avoided.  Containers which are equipped with such valves can be stored in any arbitrary position.

Abstract: Sheet  material  (30)  is  cut  into  rectangular segments (35).   The segments are then moved parallel to  their  cut  edges  rapidly  away  from  the  cutting station  into a slower operating  first sewing  station (40) where elastic bands are sewn to the cut head and foot edge portions of the segment.  The rapidly moving trailing portion of the segment (35) of sheet material is temporarily accumulated at the accumulation station (39) and progressively fed  at a lower rate from the accumulation station to the first sewing station.  The head and foot edge portions are folded into overlying relationship  with  respect  the  main  body  portion  by passing the main body portion through a U-shaped turn and at the same time passing the head and foot edge portions through a pair of 90 degree turns.   Sewing machines are moved first inwardly and then outwardly across the folded edge portions of the segment, thus forming  the  sewn  line  of  chain  stitching  at  the corners of the bedsheet.

Abstract: Wood and wood based materials are bonded with curable amino-formaldehyde resins, preferably urea-formaldehyde resin, in the presence of a ketone-formaldehyde resin. The presence of the ketone-formaldehyde resin gives an increased penetration of the adhesive and a wetting effect. The ketone-formaldehyde resin can be mixed into an adhesive-curing agent composition, into the adhesive or the curing agent. Acetone-formaldehyde resin is the preferred ketone-formaldehyde resin. Products bonded according to the method have an improved resulting strength and the method is preferably employed in high-frequency bonding and for bonding oxidized wood materials.

Filed: 1989-11-10
Granted: 2000-04-11
Abstract: The invention relates to the direct detection of human papilomavirus DNA. The recently developed polymerase chain reaction was modified in order to improve the sensitivity and specificity. By choosing appropriate oligonucleotide primers (amplimers) and reaction temperatures, individual HPV genes from among the total cell DNA can be identified and amplified to an extent such that non-isotopic detection is possible. In addition, use of reverse transcription permits selective amplification of spliced mRNA and thus permits indication of premalignant or malignant conditions and/or lesions.

Title: Geared automatic compression release for an internal combustion engine
Inventor: COUGHLIN JEFFREY P
IPC: F01L13/08
Filed: 1990-02-14
Granted: 1995-11-21
Abstract: An internal combustion engine is provided with a mechanism to release engine compression at low speeds thereby facilitating starting of the engine. The engine has an exhaust valve which is operated by a valve lifter following a cam surface.  A cam pin is positioned within a seat in that cam surface in a man-ner which allows the pin to rotate.  A drive member is attached to the cam pin and has gear teeth in a peri-pheral edge.  A flyweight has teeth which engage the gear teeth of the drive member and cause a rotation of the cam pin in response to engine speed.  At relatively low engine speeds an eccentric portion of the cam pin extends above the cam surface so as to engage the valve lifter producing an opening of the exhaust valve during the compression portion of the engine cycle.  At higher engine speeds the cam pin is rotated so that the ec-centric portion of the cam pin no longer extends above the cam surface so that the exhaust valve is not opened during the engine compression.  This operation auto-matically release of the compression at lower engine speeds.
