Title: Tethering system for a clothes washing machine having a hung-strut suspension
Inventor: TEICH DANIEL E
IPC: D06F37/24
Filed: 1998-08-21
Abstract: A tethering system is provided for a washing machine having a hung strut suspension. The tethering system includes a pair of pulleys or cams pivotally mounted in the cabinet. A pair of subframe straps are secured between the cams and the subframe of the hung assembly. An anti-rotation strap extends partially around the tub with opposite ends secured to the cams.      When the tub of the machine is filled with water, the hung assembly moves downwardly due to the weight of the water, thereby rotating the cams which tighten the anti-rotation strap into frictional engagement with the tub. Thus rotation and oscillation of the tub is prevented during the agitation and low speed spin cycles of the machine.

Abstract: Compositions and methods for the deposition of ettringite (3CaO.A12O3.3Ca(SO4).30-32H2O) onto the surfaces of fibers, aggregates, and other fillers. The ettringite is produced in situ within an aqueous suspension while in proximity to the fibers, aggregates, or other fillers to form a mineralized composite material comprising ettringite coated fibers, aggregates or other fillers. Ettringite treated fibers, aggregates, or other fillers are formed by adding chemical reactants such as calcium oxide and aluminum sulfate, which react together in the presence of water to form ettringite, which then precipitates onto the surface of the fibers or other substrates being treated. The ettringite treated fibers, aggregates or other fillers can be added to hydraulically settable materials to improve the chemical and mechanical bond between the fibers or other substrates within the resulting hardened hydraulically settable composite material, particularly a cementitious or concrete material.

Inventor: WHELAN CHRISTOPHER
IPC: E01B21/00
Filed: 1998-10-22
Abstract: A clip for securing a rail seal element to a rail includes a generally L- shaped first clip member having a clamping arm and an elongate connector arm extending from one end of the clamping arm and capable of passing under the rail; a second clip member removably slidable on the connector arm; and a locking mechanism capable of releasably locking the second clip member against sliding movement along the connector arm. In use, the second clip member is removed from the connector arm so that the connector arm can be passed under the rail with minimum disruption of the ballast. The second clip member is then slid back onto the connector arm, and the assembled clip then oriented so that the rail and the rail seal are positioned between the clamping arm and the second clip member. The second clip member is then slid on the connector arm toward the clamping arm so as to tightly press the rail and rail seal therebetween. Finally, the second clip member is locked onto the arm to prevent the clip from releasing the rail and rail seal. A tool for setting the clip includes a lever arm, and cam body and a pivot pin mounted on a nose of the cam body. By this means, movement of the second clip member toward the clamping arm is caused by inserting the pivot pin into a tool notch on the first clip member and thereafter pivoting the tool, about the pivot pin, toward the clamping arm. Subsequent pivoting of the tool away from the clamping arm causes the locking mechanism to automatically engage to prevent the second clip member from moving away from the clamping arm.

Title: Collection and deposition of chopped fibrous strands for formation into non-woven webs of bonded chopped fibers
Inventor: HEISLER DANIEL F
IPC: D04H1/70
Filed: 1997-04-30
Abstract: An air cannon (100), formed by associating an inlet cone (116), an air amplifier (104) and an outlet core (124) with one another, receives chopped fibers and forcefully deposits the chopped fibers on a collection surface (102) or web moving beyond an outlet end (126) of the outlet core (124). A binder is applied to the resulting mat (172) of chopped fibers, the binder is activated by the application of energy with the resulting treated mat (182) being compacted, cooled and rolled up to form a chopped strand mat package (194). For wide mats, one or more banks (130) of air cannons (100) extend across the moving collection web. The air cannons (100) of each bank (130) are alternately directed up-line and down-line of the web to reduce interference between the air cannons (100) by means of L-shaped support rods (136) which have generally horizontal and generally vertical legs (136H, 136V) which are separated from one another by acute and obtuse angles (140, 142) for up-line and down-line direction, respectively.  The air cannons (100) can also be individually adjusted to vary the aimed direction of the air cannons (100) across the web by rotation of the generally horizontal legs (136H) of the L-shaped support rods (136). The air cannons (100) forcefully direct chopped fibers to the web to overcome air turbulence within a forming hood (170) and forces due to static electricity.
