    Abstract: A universally articulable supporting sheath comprises an interconnected series of links, each having a convex spherical surface at one end, and a concave spherical surface at its opposite end. The concave and convex surfaces mate with one another to form the sheath. Special links having branch openings may be provided. Various forms of waterproofing seals are provided, including O-rings, axially compressed rings, flexible belts, and ridges on the spherical surfaces. The links can be fitted together by thermal expansion. However, an axially split link is also described, which comprises two parts which snap together. The split parts may be molded as a unit with an integral thin wall hinge. The bending characteristics and bending radius of a sheath can be modified by insertion of spacers between the links at selected locations, or by the insertion of pins into radial holes provided in the links. Spacers with tongues may be used to prevent rotation of the links about the sheath axis, while allowing unidirectional articulation. Projections on one of a pair of mating spherical surfaces can be engaged with holes, slots or recesses of rectangular or other shapes to produce various limits on articulation and rotation. A single link may be provided with several alternatively usable holes, recesses and the like. The outer surface of a link can be provided with an axial extension engageable with a surface of an adjoining link to prevent back bending, or to prevent bending altogether.

    Abstract: An apparatus for shaping a tube into circle includes a dummy rod to be engaged to a rear end of the tube for constituting an extention of the tube and a support for supporting the combination of the tube and the dummy rod so that the combination is movable toward the front end of the tube. The support initially supports the tube section of the combination and finally supports the dummy rod section of the combination. A heater is located in front of the support for locally softening the tube. A turning arm is coupled at its free end to the front end of the tube for pulling the tube along a circle around the axis of the other end of the turning arm so that the tube is shaped into a circle defined by the turning movement of the turning arm. A motor moves the combination ahead.

    Abstract: Printheads and design of printheads. In one embodiment, a printhead comprises a plurality of jetting channels, and a manifold apparatus fluidly coupled to the jetting channels. For each jetting channel, the printhead includes a first fluid path between the jetting channel and the manifold apparatus, and a second fluid path between the jetting channel and the manifold apparatus. The jetting channel is configured to jet a print fluid via pressure waves generated in a pressure chamber of the jetting channel. Lengths of the first fluid path and the second fluid path are different by a threshold length so that an arrival time of the pressure waves at the manifold apparatus are different by a threshold time.

    Abstract: Printheads and methods of operation. In one embodiment, a printhead includes a plurality of jetting channels comprising first jetting channels configured to jet a first print fluid and second jetting channels configured to jet a second print fluid, and a driver circuit communicatively coupled to actuators of the jetting channels. The driver circuit receives a drive waveform comprising first jetting pulses provisioned for the first print fluid and second jetting pulses provisioned for the second print fluid, and gating signals comprising a first active gating signal designated for jetting the first print fluid and a second active gating signal designated for jetting the second print fluid. The driver circuit selectively applies the first jetting pulses to actuators of the first jetting channels based on the first active gating signal, and selectively applies the second jetting pulses to actuators of the second jetting channels based on the second active gating signal.
