line from a sump, and returned to the sump through a similar line from the bottom of the cavity. Any small leakage of lubricant past the sealing rings is returned to the sump through suitable drain lines. This arrangement reduces noise from friction and impacts and increases the effective working force of the press.--CHA 5,127,372 43.50.Gf EXHAUST SILENCER SYSTEM FOR TWO-CYCLE ENGINE Hiroaki Fujimoto and Seiji Inoue, assignors to Sanshin Kogyo Kabushiki Kaisha 7 July 1992 (Class 123/65PE); filed in Japan 30 August 1989 An expansion chamber has a communication port through the cylinder wall so positioned as to open just prior to the opening of the exhaust port. This releases part of the exhaust gas from above the piston into the expansion chamber, and reduces the sharp pressure shock that occurs when 106 104 •o• [.-• 39 the exhaust port opens to the atmosphere. An auxiliary means for closing the communication port before the exhaust port closes is also described, as a means for minimizing the effect of the expansion chamber upon the effective compression ratio of the engine.--CHA For stapling a set of copy sheets in a copier or printer, a noise reducing clamp mechanism includes a means for proportionally varying the speed and force of a movable clamping member, such that the thinner the set of copy sheets, the lesser the speed and impact force of the movable member when it contacts the set of sheets.--CHA 5,136,924 43.50.Gf SILENCER FOR FIREARMS Theobald F6rster and Peter Goepfert, assignors to SIG Schweizerische Industrie-Gesellschaft 11 August 1992 (Class 89/14.4); filed in Switzerland 26 January 1990 For use with pistols having a fixed or tilting barrel, the design configuration described here is such that the sighting line is retained when the silencer is attached. Light-weight metal and compact structure retain ease and accuracy of handling. The width of one design is no greater than that of 49 lg 20 18 44 46 43 1• 13 48 47 15 lO 14 45 •23 a• 33 38 4• •2 •0 25 32 • 57 54 55 17 the pistol itself; off center cavities allow expansion of exhaust gas before release to the atmosphere.

Bigelow and Anil Gulati, assignors to General Electric Company 14 July 1992 (Class 60/261); filed 31 October 1990 A number of ring-shaped afterburner flameholders have V-shaped, folded cross sections and a plurality of rectangular tabs cut along the trailing edges of their opposing sidewalls. They alternate so as to introduce • 54 20 •--• streamwise and spanwise (transverse) vortices in the flowing gas. They are said to reduce resonating vortex oscillations (screech) and the consequent need for an acoustic liner to suppress such screech.--CHA 5,137,439 43.50.Gf SCREW ROTOR MACHINE WITH DE LAVAL NOZZLE FOR NOISE REDUCTION Stig Lundin, assignor to Svenska Rotor Maskiner AB 11 August 1992 (Class 418/181); filed in Sweden 17 February 1989 This is a very interesting, extremely simple means for controlling the e...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
