Self-anchoring fiber block system

A fiber block segment suitable for controlling erosion and stabilizing soil is described that comprises an elongated fiber block formed of a densely packed elongated thick fibrous material. The fiber block is wrapped with a fabric around three sides so that the fabric defines a top anchor portion and a bottom anchor portions extending from the block. The fiber block is securely attached to the wrapped fabric by another fabric or twine spanning the fourth side of the block. Additionally, the fabric is wrapped only up to the edges defining one end (a male end) and beyond the edges defining the opposite end (the female end) to define a pouch-like structure at the female end. The fiber block is made of coconut fibers (coir). The fabric is woven from coir twine, and coir twine secures the fabric to the fiber block.

Reverse acting rupture disc with laser-defined electropolished line of weakness and method of forming the line of weakness

A reverse acting rupture disc is provided having a laser defined electropolished line-of-weakness recess, and an improved method of forming an electropolished line-of-weakness recess in a reverse acting rupture disc that assures full opening of the disc upon reversal. A rupture disc blank is pre-bulged, final bulged, and then provided with a layer of resist material. A laser is used to remove at least a portion of the layer of resist material corresponding to a desired line-of-weakness recess in the concave face of the bulged rupture disc. The disc is then subjected to an electropolishing operation to remove metal from the lased area of the rupture disc, thereby forming a lustrous polished line-of-weakness recess in the disc of desired configuration and of a predetermined depth that is related to material thickness. The electropolished line of weakness is defined by spaced opposed channel portions separated by a central raised crown portion wherein the channel portions are of greater depth than the crown portion. The burst / reversal pressure of the disc having an electropolished line-of-weakness recess may be selectively controlled by varying the pre-bulging pressure on the disc.

Through weld for aluminum or aluminum alloy base metals by using high-density energy beams

This invention provides a new through weld method to carry out welding of a base metal made of aluminum or that of aluminum alloy using high energy beams wherein a shield gas ambience (an inert gas ambience) to cover a welding site in a submerged-scar is formed, even a shield gas ambience (an inert gas ambience) to cover a welding site irradiated by the high energy beams. Since the former shield gas ambience to cover the submerged-scar pushes the keyhole against the gravity and / or the gas pressure force of the latter shield gas supplied to the laser irradiation side, then the forming of hang down of beads and the resultant projection of the welding base metal are prevented.

Spinal implants and methods of providing dynamic stability to the spine

The present application discloses a plurality of spinal implants and methods for repairing annular defects in intervertebral discs and for providing dynamic stability to the motion segment of the spine in the vicinity of the repaired disc. Each of the implants comprises a head portion and a tail portion. In the illustrated embodiments, the head portion of each implant is enlarged relative to the tail portion. Each of the head portions and tail portions is adapted to support adjacent vertebrae and resist collapse of the intervertebral disc. A tapered portion of each implant engages end plates of the adjacent vertebrae to resist forces tending to push the implant out of the intervertebral space. The tail portion of each implant includes a tail flange (which in some embodiments is of similar diameter to the head portion) that abuts extradiscal lips of the adjacent vertebrae and resists forces tending to push the implant deeper into the intervertebral space.

Vertical take off and landing (VTOL) aircraft with vectored thrust having continuously variable pitch attitude in hover

The presently disclosed embodiments relate to vertical takeoff and landing (VTOL) aircraft that have the capability of hovering in both a “nose forward” and a “nose up” orientation, and any orientation between those two. The disclosed aircraft can also transition into wing born (non-hovering) flight from any of the hovering orientations. In addition, certain of the disclosed embodiments can, if desired, use only vectored thrust control to maintain stable flight in both hover and forward flight. No control surfaces (e.g. ailerons, elevators, rudders, flaps) are required to maintain a stable vehicle attitude. However, the disclosure contemplates aircraft both with and without such control surfaces.

Chute system with adjustable angle of inclination

The invention provides a chute system (C1,C2,C3) for a sorting system arranged for transporting objects, e.g. for use for discharging luggage from a conveyor system. The chute system has one or more chute sections with an inlet (IL) in one end and an outlet (OL) in the opposite end. Displacement means, e.g. a pneumatic actuator, is arranged to adjust an angle of inclination of the one or more chute sections (C1,C2,C3) by displacing the chute section (C1,C2,C3) in a motion comprising pivoting around a pivot point positioned downstream of the inlet (IL). E.G. the pivot point can be positioned at the outlet, e.g. by means of a hinge. The adjustment of the angle of inclination may be controlled by a processor in response to various position and / or speed sensors and / or information about incoming objects from a vision based system or from the associated sorting system, e.g. identification of poly wrapped objects. The angle of inclination can be increased in case an object stops on the chute section, or the angle of inclination can be decreased in case an object moves too fast, even if a simple gravity chute is used. A cascade of two or more chute sections (C1,C2,C3) with adjustable angles of inclination can be used to control batches of objects and to control back pressure of objects on the chute.

Head suspension assembly contributing to constant flying height of head slider

An adhesive layer is interposed between a head slider and a support member for fixing the head slider to the support member. A deformation body is interposed between the head slider and the support member. The deformation body has a coefficient of thermal expansion larger than that of the adhesive layer. The deformation body expands in response to rise in temperature. An internal force is induced in the head slider so as to distance the head slider away from the support member. Since the adhesive layer serves to fix the head slider to the support member, the internal force is transformed into stress in the head slider. The thermal expansion induces stress in the head slider in response to the rise in temperature. The stresses are balanced with each other, so that the head slider is prevented from deformation.

Self-seeded single-frequency laser peening method

A method of operating a laser to obtain an output pulse having a single wavelength, comprises inducing an intracavity loss into a laser resonator having an amount that prevents oscillation during a time that energy from the pump source is being stored in the gain medium. Gain is built up in the gain medium with energy from the pump source until formation of a single-frequency relaxation oscillation pulse in the resonator. Upon detection of the onset of the relaxation oscillation pulse, the intracavity loss is reduced, such as by Q-switching, so that the built-up gain stored in the gain medium is output from the resonator in the form of an output pulse at a single frequency. An electronically controllable output coupler is controlled to affect output pulse characteristics. The laser acts a master oscillator in a master oscillator power amplifier configuration. The laser is used for laser peening.
