A panel fasteners (20) is disclosed in the form of a hook and cam assembly (21) having two side walls (24) with a boss (27) through which a cam shaft (28) is journalled. The cam shaft has a socket (29) and a round cam (30). A hook (32) is frictionally mounted in camming engagement with the cam. A leaf clutch spring (33) is mounted within a spring mounting notch (36) and in frictional engagement with a substantially round cam engagement hole (34) of the hook. To position the spring into the spring mounting notch and cam engagement hole the spring is pre-compressed prior to mounting it within the spring mounting notch by forcing it through a narrowing channel positioned adjacent the cam.

An open frame prosthesis is formed with looped end terminations at its proximal and distal ends. At one end of the prosthesis, the filaments or strands are welded together in pairs to form strand couplings. A plurality of loop segments are connected to the strand couplings, one loop segment for each pair of adjacent strand couplings. In one version of the prosthesis, strands at the opposite end are bent to form looped ends. In another version, loop segments are connected to pairs of strand couplings at both ends of the prosthesis. The loop segments can be connected to the couplings by welding, fusion bonds, or tubes, which are either crimped or heat shrunk.

A decorating machine particularly for the decoration of ceramic products, and a method for realizing a belt for decorating said ceramic products, wherein the machine comprises: a closed loop belt (3) for the transfer of a decoration (9) on a receiving surface (11) of a ceramic product; a plurality of conveyor rollers (2) about which said belt (3) is wound and moved in rotation; at least one of said conveyor rollers (2) comprises a central portion (12) and two end portions (14) opposite one another, at least one of said end portions (14) being free in rotation with respect to the other said portions (12, 14).

A method for constructing a cage body of a tapered cage assembled in a rigid-flexible manner includes steps as follows. A cage body of a tapered aquaculture cage is assembled by combining a rigid-structure copper alloy stretched mesh and a flexible synthetic fiber mesh. Pipe rings mounted on the standard component of the synthetic fiber mesh are mated in a staggered manner with plugging rings on the standard component of the copper alloy stretched mesh, and high-performance synthetic fiber rope is rove through the pipe rings and the plugging rings; in this way, the connection is completed. The cage effectively improves the cage resilience under the ocean current condition, avoids mesh sheet deformation or corner breakage, enhances the water exchange capability in and out of the cage body of the gravity cage, and effectively improves the growth environment for the fishes farmed in the cage body.

Disclosed are alkali aluminosilicate glasses having unexpected resistance to indentation cracking. The glasses obtain this high resistance as a result of a high level of surface compression accompanied by a shallow depth of layer. The advantaged glasses show greater resistance to radial crack formation from Vickers indentation than glasses with the same compressive stress, but higher depths of layer.

A grommet is at least partially comprised of a clear, rigid material is disclosed. The body of the grommet tapers from a proximal end to a distal end, allowing the grommet to be guided into a hole in a post of a handrail system. The interior of the body includes an longitudinal cannulation open to the exterior of the grommet via a helical cut in the surface, allowing for a wire rope to pass through. The grommet can be installed whether or not a wire rope has previously been passed through a railing post.

A grooved-ended resilient expansion joint is disclosed. The expansion joint has a resilient expansion member with a central resilient portion and two resilient axially disposed cylindrical ends. Each cylindrical end has a radially outwardly raised distal cylindrical gasket portion with at least one inside shoulder having an inner diameter sized substantially the same as an outer diameter of a pipe to be joined. Each cylindrical end also has a neck portion between the central portion and the gasket portion that is sized to receive a grooved-ended pipe nipple.

An electronic device includes an electronic circuit board containing a processing element and a vision sensor. A carrier frame is used to support the electronic circuit board. An optical element is positioned over the sensor and supported by the carrier frame. The electronic circuit board is bent to reduce the length, thickness and/or width of the electronic device, without increasing the others of the length, thickness and/or width of the electronic device.

The invention is directed to a method for improving the fatigue behavior of the body (2) of a gas valve, the body comprising at least two bores (4, 10) and at least one bore intersection (20) defining an internal volume; wherein the method comprises the following step: subjecting the internal volume to an autofrettage by applying a pressure of comprised between 100 MPa and 500 MPa by means of a liquid. 10. The invention is also directed to a gas valve body (2) comprising at least two bores (4, 10) and at least one bore intersection (20) defining an internal volume with an internal wall; wherein the internal wall is treated by autofrettage resulting in compressive stresses at the intersection or at least one of the intersections.

A vacuum filter device comprising a filter body having two holders on opposite sides of a filter. Each holder contains a closed container in a fluid-tight, sealed relationship. The filter is retained by a compression sealing element and the sealing element is maintained in place by a compression element formed of a ring. The compression element is bonded to a portion of the body to hold it, the sealing element and filter in place under a compression seal. Optionally a port in the compression element is formed to align with the vent of the device. Further, an alignment feature on the compression element ensures the port is in alignment with the vent of the device. The device also includes a vacuum port communicating with the downstream side of the filter, and hence the filtrate container.
