Abstract: A cleaning catheter (200) includes fluid-delivery and suction lumens (520, 530). A flow regulator (700) defines suction and fluid ports (830, 827). A mechanical user control element (320) is configured to mechanically and non-electrically set activation states of the flow regulator (700), and transition between first and third configurations via a second configuration. When the control element (320) is in the first configuration, the flow regulator (700) blocks fluid communication (a) between the suction port (830) and the suction lumen (530) and (b) between the fluid port (827) and the fluid-delivery lumen (520). When the control element (320) is in the second configuration, the flow regulator effects fluid communication between the suction port (830) and the suction lumen (530), and blocks fluid communication between the fluid port (827) and the fluid-delivery lumen (520).

Abstract: A system as disclosed herein uses a cold or unheated water source such as a reservoir or a pressurized inlet feed line, and a heated water reservoir. The unheated water reservoir is pressurized with a pressurizing apparatus communicating with the unheated water reservoir. Such a pressurizing apparatus may include an air pump, bladder or piston arrangement as well as other pressurizing apparatus. The pressurizing apparatus is controllable to push water from the unheated water reservoir to the heated water reservoir. As a result of the pressurization and displacement of the unheated water, heated water is then displaced and forced from the heated water reservoir. Heated water from the heated water reservoir is dispensed to the spray head and over the beverage brewing substance such as coffee for brewing.

Abstract: A method of repairing and renewing a manhole chimney utilizes a circumferentially stretchable liner sleeve which is inserted into the manhole and pressed by an inflatable bladder into engagement with the walls of the manhole chimney. The sleeve is coated with an uncured resin, which is allowed to cure as the sleeve is pressed against the chimney walls, thereby attaching the sleeve to the walls of the manhole chimney. The stretchable sleeve eliminates air spaces between the sleeve and the chimney walls, and precludes formation of undesirable folds in the sleeve. The sleeve stretches circumferentially up to 150% of its unstretched diameter, while having a substantially unstretchable length.
