This invention overcomes the disadvantages of the prior art by providing a power generating system particularly suitable for field use in remote locations, which is fuel-efficient, relatively quiet, tolerant of dust, capable of operating on low grade logistics and diesel-like fuels and capable of generating between 500 W and 2 KW of continuous electrical power. This generator employs a miniature internal combustion engine/generator (MICE) having a piston moving within a cylinder arranged for two-cycle operation, and an interconnected, axially arranged piston shaft that oscillates an alternator coil within a magnetic core. The piston shaft is opposed by a strong, multiple-helix spring. The cylinder head, in which the piston operates, is cooled by moving (electrically pumped) fluid in a cooling head, or by another heat-transfer mechanism. The MICE generator's intake arrangement includes a preheater heated by a heated fluid flow thereon. The MICE generator is vibration-isolated using a base that supports the MICE on a plurality of soft coil springs. The MICE generator is encased in an acoustic enclosure having a shell composed of sheet metal or another stiff material extending from the base plate and being covered by a top side. Holes in the enclosure top are covered by porous discs that allow exhaust gasses from the internal muffler to pass therethrough. The acoustic enclosure resides in a large, typically portable, external package enclosure.

The present invention is a jig system for precisely positioning the placement of multiple cuts such as in the placement of dovetail or box joints cut in a wood panel. A row of multi-use adjustable spacers controls the indexing of a workpiece and can be used with a stationary and/or a portable cutting tool. The movability of the spacers permits a workpiece to be cut on both sides of a guide bar fence thereby assuring that the first cut will always be made on the same side of a drawer and will be esthetically pleasing regardless of the width of the workpiece. Additionally, the adjustability of the spacers accommodates any desired cutting tool height, angle and/or size. The jig system comprises: a stationary fixture; a spacer bar; a plurality of spacers engaged with the spacer bar, the spacers are adapted for lateral and rotational movement along the spacer bar thereby providing an engaged and non-engaged working mode; a sliding member adapted for lateral movement on the stationary fixture and for engaging at least one of the spacers in the engaged working mode; and means for holding the spacer bar and connecting the spacer bar to the stationary fixture while engaging with at least one of the spacers during the engaged working mode.

A papermaker's fabric, usable in the forming section of a paper machine, having a top layer and a bottom layer of cross-machine direction (CD) wefts. The top (forming) layer and bottom (wear side) layer are woven together to form a multi-layer fabric. CD packing yarns are inserted between adjacent wear side weft yarns. The packing yarns reduce the void volume on the wear side of the cloth without significantly disrupting the air permeability or increasing the caliper of the fabric. The placement of the packing yarns also adds to the CD stability and seam strength of the fabric and reduces the lateral movement of the wear side weft yarns.

The interengagement between the base member and the bumper requires no additional interconnecting or attachment members. The base member includes a pair of elongated arcuate male members which receive arcuate complementary female interconnecting elements extending from the bumper. Free end portions of the assembly may include cap elements of flat or spherical shape to enclose the ends of the strip assemblies.

The invention relates to a steerable soil displacement hammer for horizontal ground boring, comprising a body that can be rotated by means of a longitudinal element, and a thrust head that is mounted rotationally in relation to the body. A rotation of the body in relation to the thrust head causes the thrust head to pivot out into an asymmetrical constellation or to pivot to a symmetrical constellation. The invention also comprises a retaining feature which provides a hold in the environment and which permits a relative rotation of the body and simultaneous pivoting of the thrust head. The soil displacement hammer can be driven forwards or backwards and the retaining feature is situated in the area of the pivot axis of the thrust head.

The invention discloses a fixing device, a fixing method and an application method for reconstruction of cruciate ligaments. The fixing device comprises a driven nail and an expansion nail sleeve. In an unexpanded state, four axially-extending grooves are formed on the peripheral side surface of a sleeve body in an inwardly and radial sinking mode. By means of the grooves, splitting of ligaments is achieved. In an expansion state, the driven nail is inserted into a sleeve body by means of an opening. Under the effect of the driven nail, the grooves are outwardly extruded so that expansive fixation is achieved. The fixing device, fixing method and application method for reconstruction of cruciate ligaments have following beneficial effects: 360-degree uniform expansion of the expansion nail sleeve is ensured; the expansion nail sleeve is prevented from being broken; transported tendons are not cut by the surgery of reconstruction of ligament; tendons are divided into four bundles by extrusion in a radial direction for effective fixation; fine fixation effect is obtained; full contact among transported tendons and a bone tunnel is achieved; recovery of tendons and bones is further promoted so that the fixing device is suitable for operative habits of a doctor; and the fixing device is easily and conveniently used without additional learning.
