Abstract: A bathing support device for use in bathing disabled persons that includes a water permeable platform upon which the disabled person can lay. The platform is supported a predetermined height over the bathtub by front and rear leg assemblies. The front leg assemblies extend from the platform and engage the floor proximate the front of the bathtub. As such, the front leg assemblies can cause no damage to the bathtub or its finish. The rear leg assembly extend from the platform and engage the bottom surface of the bathtub, which can support the forces applied by the rear leg assembly without damage. The orientation of the legs is designed to provide a stable support for the disabled person, thereby removing the concerns and dangers of having the support tip while the disabled person is supported by the platform.

Abstract: One or both of the lap rollers on which a lap roll is mounted for unwinding purposes is driven with an increasing speed during the winding-off interval so as to maintain the thickness of the lap layer constant. This, in turn, maintains the count of the sliver to be formed in the comber at a constant number. The increase in the lap roller drive can be made dependent upon the length of the lap layer which is unwound from the roll, on the mass of the lap layer delivered to the comber or on the mass of a sliver produced from the combed lap as measured at a point downstream of the comber. The speed may be increased in a stepwise manner or continuously.
