Abstract
Abstract PCT No. PCT/GB86/00064 Sec. 371 Date Sep. 17, 1986 Sec. 102(e) Date Sep. 17, 1986 PCT Filed Feb. 6, 1986 PCT Pub. No. WO86/04537 PCT Pub. Date Aug. 14, 1986.A manipulative device capable of remote operation has a nozzle head having one or more nozzles adapted to eject a fluid stream having a component at right angles to the axis of the nozzle head. There is a flexible elongate hose for connecting the nozzle head to a source of remote operation, such as a joystick arrangement. Also valves capable of operation by tendons parallel to the flexible elongate hose enables spatial positioning of the nozzle head by remote differential operation of the tendons. The device may be used in various applications for example borehole mining, paint spraying etc.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
114 words
A manipulative device capable of remote operation comprising in combination: a nozzle head having an axis and one or more nozzles adapted to eject a fluid stream having a component at right angles to said axis, a flexible elongate member connecting said nozzle head to a reference point, said nozzle having means for controlling said fluid streams through said nozzles, tendons operably connected to said fluid control means, said tendons being adapted to follow the curvature of said flexible elongate member so as to impart feedback of said nozzle head position, whereby in use, remote differential operation of said tendons enables spatial positioning of said nozzle head, by said one or more fluid streams.
Claim 2
Dependent Claim
114 words
A manipulative device capable of remote operation comprising in combination: a nozzle head having an axis and one or more nozzles adapted to eject a fluid stream having a component at right angles to said axis, a flexible elongate member connecting said nozzle head to a reference point, said nozzle having means for controlling said fluid streams through said nozzles, tendons operably connected to said fluid control means, said tendons being adapted to follow the curvature of said flexible elongate member so as to impart feedback of said nozzle head position, whereby in use, remote differential operation of said tendons enables spatial positioning of said nozzle head, by said one or more fluid streams.
