6/539821

Inventors:

Raymond A. Simpson - High Point NC

International Classification:

A46B 1306

US Classification:

15 29

Abstract:

A scrubber assembly including a housing having first and second remote sides is provided and the housing includes rotary scrubber structure journalled therefrom facing and disposed outwardly of the first side of the housing. The second side of the housing includes liquid inlet structure and the housing contains a liquid driven motor including a rotary output shaft upon which the scrubber structure is mounted. The housing includes a liquid outlet structure and the motor is operative to receive liquid under pressure from the inlet structure, to discharge liquid from the liquid outlet structure and to develop rotary torque input to the shaft as a result of liquid flow therethrough from the inlet structure to the outlet structure. The housing includes structure coacting with an associated hand held spray head of the type including a flexible water inlet supply hose and a plurality of liquid spray jet outlets opening outwardly of one side of the head for releasably mounting the housing from the head with at least one of the spray jet outlets in sealed communication with the liquid inlet structure for the motor housing.

Abstract:

Cut-off malfunctions in a communication network are lcoated by establishing a connection through the network between a first terminal and a second terminal. At the first terminal, a prescribed sequence of first signals is generated and applied to the established network connection. At the second terminal, a second signal is generated responsive to receipt of a first signal over the established connection and the second signal is applied to the established network connection. A signal representing the difference between the number of first signals applied to the established connection and the number of second signals received from the established connection is formed at the first terminal. The established connection is maintained for testing when the difference signal exceeds a predetermined number.
