Abstract: An individual controlled needle tufting machine has a reciprocating latch bar for latching and unlatching to selective needle carriers, each needle carrier being guided in a respective guide formed in a guide block and carrying a respective needle so that each needle selectively may be driven by the latch bar. The tufting machine has mechanism for laterally shifting the latch bar and needle carriers, whether latched or unlatched to the latch bar, together with guide blocks. The latch bar and the brackets to which the guide blocks are mounted are formed from aluminum alloy to which laterally extending tubes are fastened. Water, cooled by refrigeration, is circulated through the tubes so that the thermal expansion of the aluminum alloy elements are not substantially greater than the remainder of the tufting machine.

Abstract: A bow sight includes a housing which is mounted on an archery bow and carries electronic circuitry including a series of aligned target LED's which may be programmed by an archer to correspond to different respective target distances. The housing mounts a color separating dichroic filter sight glass positioned at an angle between upper and lower housing walls. The LED's are positioned to overlay an elongated slot in the top wall so that a lighted LED reflects onto a surface of the glass and may be viewed for sighting a target. Two other LED's, one on each side of the target LED's, are included in the circuitry and may be programmed to light when the bow is tilted to a selected side-wise position, apertures in the top wall of the housing permitting reflection of each of these LED's onto the sight glass. After each target LED have been programmed, the archer may sight through the sight glass and align the reflection of the lighted target LED onto the target.

The slats are mounted on chains fastened to sprockets mounted on a driven shaft.

Abstract: An inshot-gas burner for gas burning furnaces and other gas burning appliances has a flame retention head at the outlet formed from porous ceramic foam with a central opening through which a flame may project. A velocity reducing insert is located within the mixing chamber of the burner for reducing the velocity of the mixture received by the head in the area spaced about the central openings so that the head is radiant in operation. The porosity of the foam is in the order of 20 to 60 pores per inch. When radiant, the head permits the burner to operate at higher primary aerations, and provides faster burning velocity and thus lower residence time, and additionally provides a lower maximum temperature and a stable quiet flame. This permits the burner to emit low amounts of nitric oxide and nitrogen dioxide without increasing the amount of carbon monoxide emissions.

Abstract: A hand-held mending gun for tufting stitches into a backing material has a hollow needle reciprocably driven axially and oscillated laterally so as to form stitches in a backing material laterally offset from other stitches. Zig-zag backstitches may thus be formed as may other laterally offset stitches. A crank drives a needle carrier in a reciprocating path extending longitudinally along the axis of the needle. The elongated path is defined by constraining the needle carrier to move within a slot in a pivotally mounted yoke member having a pair of spaced apart tines disposed about a cam so that rotation of the cam oscillates the yoke member about the pivot. The cam is driven by gears such that it may make one cycle For each two cycles of reciprocation of the needle to form alternate laterally offset stitches. Cams of various configurations may be utilized so that more than one stitch may be provided at each lateral side.
