Title: Pressure relief panel hold open apparatus and method
Inventor: VINCENT WILLIAM
IPC: E06B5/12
Filed: 1991-06-13
Granted: 2006-03-21
Abstract: A pressure relief panel assembly for protecting a building against over-pressure caused by explosion.      The assembly has a panel pivotally connected to a frame and held by a calibrated magnet and striker set which releases when a predetermined over-pressure occurs. A linkage of two arms limits the extent to which the panel can blow open, and a spring mounted on one of the arms catches the other arm when the panel has blown open, pre-venting the panels from re-closing and thereby preventing implosion damage to the building. Alternatively, the panel, after opening, may be held partly open by a stop bar which pivots downwardly so that its end engages the magnet face, thus holding the panel partly open to pre-vent implosion damage to the building after the explo-sion.

Granted: 1997-04-22
Abstract: A method for forming stabilized preforms for complex composite articles is disclosed using a solid meltable uncatalyzed thermosetting resin as the stabi-lizing agent.  The resin is applied to each layer of the preform and heated to melt the resin and bond the layers together.  After cooling, the resin resolidifies but does not set and thereby holds the layers in the desired preform shape.  The layers can be first formed into a flat sheet as a raw material from which shaped preforms can be made by cutting the sheet into sections which are placed over a mandrel and reheating to thereby remelt the solid resin to allow the preform to conform to the shape of the mandrel.  Utilizing this process allows complex composite parts to be easily preformed and assembled prior to placement in a mold for resin injec-tion molding, without inhibiting part strength as the resin is compatible with the injection resin and is co-catalyzed by the catalyst contained in the injection resin.

Abstract: Synthetic diamond film produced by chemical vapor deposition can be crushed to obtain diamond grit which has useful abrasive properties.  The flexibility of CVD deposition processes in determining diamond film properties means that CVD diamond grit properties can be tailored to particular abrasive applications.  In a disclosed embodiment, the grit particles are coated with a magnetic material.  The coated grit particles can then be aligned with a magnetic field, and the coated grit particles are bonded to a matrix while aligned.  In a further disclosed form of the invention, a chemical vapor deposition system, such as an arc jet plasma deposition system, is provided in a chamber.  A carrier strip and the deposition system are moved with respect to each other, and the deposition system is caused to deposit diamond film on the carrier strip.  The strip can be of a flexible material, such as a copper or woven graphite material, and can be wound onto supply and take-up spools, respectively, before and after diamond deposition.  Diamond film can be removed from the strip, such as by flexing the strip, and then crushed to obtain grit.  The deposition system can also be utilized to produce other superabrasive grit, such as cBN, C3N4 or B22O.

Granted: 1996-09-10
Abstract: A method and apparatus for controlling the readout rate of information from a sequential storage medium, such as a CD-ROM,   to  maintain   synchronism  between  the   device containing the medium and an independent receiver receiving the information.  Information is loaded from the media into a buffer at a rate controlled by pulses from a device clock. Information is unloaded from the buffer for utilization by the receiver independently of the loading of the buffer. The amount of free space available in the buffer is measured as information is  loaded into the buffer.   The rate of the clock is dynamically adjusted in response to the amount of free buffer space to maintain the full state of the buffer within predetermined limits.   In this manner,  the buffer never empties or fills in response to the unloading by the independent receiver.

Abstract: A method for making an absorbent article, such as a sanitary napkin, having tabs. A first series of patches of a hot melt type pressure sensitive adhesive are applied to one side of a double-sided release strip. The release strip is then placed against the central portion of the absorbent article so that the first adhesive patches bond to the central portion. A second series of patches of the adhesive are applied to the other side of the double-sided release strip and tabs are folded over the central portion so that the second adhesive patches bond to the tabs.      Since the release strip has been coated with a release agent, such as silicone, on both of its sides, the first and second patches of adhesive bond to the central portion and the tabs, respectively, with greater tenacity than they did to the release strip. when the user removes the release strip prior to use, the first and second adhesive patches remain on the central portion and the tabs. Thus, a hot melt type of pressure sensitive adhesive is applied to the central portion and the tabs without danger that they will be scorched by the heat of the hot melt adhesive as it leaves the glue gun.
