Abstract:
A coating system for inner wall surfaces of tubes (14) includes flexible hoses (5) each carrying an applicator nozzle (15) through which the coating substance is dispensed. A payout guide assembly (7, 8, 9, 10, 11) feeds the nozzles into a hose reel (4) from which they are unwound through the payout guide (7). The reel (4) can also be driven in reverse for removing the nozzles (15) from the tubes (14) and winding the hoses (5) onto the reel (4). A paint spray system includes a paint pump assembly (16) and a spray gun valve (18) connected between the hose (5) and the paint pump assembly (16). A control system (2, 3) is connected to the payout guide (7), to the hose reel (4), if necessary, and to the spray gun valve (18). The control system coordinates the feeding and removing of the hose (5) into and from the tube (14), as well as the paint application through the spray gun valve (18) and the applicator nozzle (15).
Abstract:
A compression system and method of manufacturing a compression system are provided. The compression system includes a compressor, and a tank rotatably coupled with the compressor and configured to receive a compressed fluid therefrom. The compression system further includes a sheave configured to receive a hose, with the sheave being coupled with the tank such that the sheave and the tank are rotationally fixed relative to one another and rotatable with respect to the compressor.
Abstract:
Method and apparatus for controlling fluid leakage from sections of a pressurized fluid system (12) adapted to provide fluid at line pressure to equipment associated therewith includes means (26, 28, 29, 66) for sensing first and second conditions indicative of non-use and a usage demand respectively of the equipment (18) and for generating a signal indicative of one of the conditions and control unit means (24) for selectively isolating and effecting communications between line pressure of the fluid system and the system section in response to the condition-indicating signal. According to a first embodiment (Fig. 2) the first non-use and second usage demand conditions are constituted by respective lower and higher rates of fluid flow through the section (20a, 20b) of the fluid system in which leakage is to be controlled. According to a second embodiment of the invention, the first non-use and second usage demand conditions are constituted by support and non-support of the equipment (18c, 18d) respectively or non-movement and movement of the equipment (18e) respectively.
