Title: Asymmetric damping tensioner belt drive system
Inventor: LIU KEMING
IPC: F16H7/12
Filed: 2002-05-23
Abstract: The invention comprises an asymmetric damping tensioner (10) system for belt drives on an engine. A belt (16) is connected between a driver pulley (18) on a crankshaft and any number of driven pulleys. Each drive pulley is connected to an accessory such as an alternator, power steering pump, compressor or the like. The tensioner (10) is placed anywhere before the first component of significant effective inertia, in the belt movement direction. A biasing member (70) in the tentioner is used to maintain a tention in the belt. The tensioner further comprises a damping mechanism (34) to damp belt vibrations caused by the operation of the engine. Tensioner damping friction is unequal or asymmetric, depending upon the direction of movement of the tentioner arm (52). During acceleration the damping friction of the tentioner (10) in the unloading direction is significantly lower than the damping friction in the opposite, or loading direction, as is the case during deceleration. Lower damping friction during acceleration allows the tensioner arm (52) to quickly adjust to the increase in belt length caused by acceleration. Higher damping friction during deceleration prevents the tensioner arm (52) from being moved too far in the loading direction thereby causing slipping and noise.  Asymmetric damping also significantly diminishes overall vibration in the belt during all phases of operation.

Abstract: A vertical pouch forming, filling and sealing machine (10) and method for making pouches (22) and filling same with a liquid content in the range of about 5 to 20 liters, is described. As a pouch is being filled with a liquid (49) it descends into a support cage (47) to restrain the pouch (22) from ballooning out and prevents the weight of the liquid in the filled pouch from tensioning the film (14) in the hot horizontal seal zone of the horizontal sealer (21). The support cage (47) compensates for loss of surface tension of the film in the hot horizontal seal zone during the horizontal sealing cycle.  The cage (47) also has a gate section (56) to discharge the filled pouch by gravity after the horizontal sealing cycle.

Abstract: The present invention provides a dispersant and foaming agent combination that is useful in the production of gypsum wallboard and other aqueous cementitious products, a method of forming a gypsum wallboard and a gypsum wallboard. The dispersant in the combination according to the invention is a naphthalene sulfonate-aldehyde condensate alkali salt polymer having a weight average molecular weight of from about 17,000 to about 47,000. The alkali is preferably an alkali metal and/or an alkaline earth metal. The aldehyde is preferably formaldehyde. The foaming agent used in the combination according to the invention is a soap, preferably an alkali salt of an alkyl ether sulfate and/or an alkyl sulfate. The combination of a high molecular weight dispersant and a foaming agent produces a gypsum wallboard core effect that more efficiently entrains air (i.e., creates void space), thereby lowering overall board weight without detrimentally affecting strength. A gypsum wallboard formed using the dispersant and foaming agent combination according to the invention exhibits a higher nail pull value than gypsum wallboard formed using a conventional dispersant and a foaming agent at the same solids loading ratio.
