Abstract: A retainer provides for the prevention of lateral slippage or movement of a toilet seat or a toilet bowl rim. Typically, bowl rims are not uniformly level or even, and conventional bumpers, along with the play generally found in the seat hinges, allow a seat to slip laterally relative to the rim, and occasionally drop slightly as the bumper(s) is/are displaced to one edge of the bowl rim as the seat shifts. The present retainers each include inner and outer depending retainer portions, which serve to prevent lateral displacement of the seat in either direction relative to the rim. Thus, only a single retainer is required, although preferably two are installed on opposite sides of the seat bottom and toward the front of the seat for uniformity. The present retainers include a resilient intermediate portion, which allows the depending retainer portions and member from which they depend, to arcuately rock to accommodate uneven bowl rims. The device(s) may be mechanically or adhesively secured to the seat bottom.

Cleaning nitrogen gas as a barrier gas is supplied to the major surface of the wafer so as to prevent a contaminant from being scattered from the reverse surface and attached to the major surface.

Abstract: Conditioned gas flows are applied at various critical locations in instruments and apparatus for testing and processing textile fibers, such as cotton. In the context of test instruments, a standard test zone environment (which becomes part of the test record) is effected by the introduction of controlled conditioned gas flows directly into a testing zone, including into testing instruments themselves. In the context of processing apparatus, direct control of processing performance parameters is effected by "controlling parameters", which are in turn effected by the application of conditioned gas flows. A plurality of "performance parameters", which may be in conflict with each other, may be controlled in accordance with a predetermined compromise control strategy, carried out by feedback or feedforward control systems implementing modern statistical control approaches.
