Abstract: A collimator for use with an optical fibre includes a holder for the fibre, the holder having a V-shaped recess at the bottom of which the fibre is held in place. The collimator also includes an optical member able to transform a light beam from the fibre into a parallel beam, the optical member being fixed with respect to the holder. The holder and the optical member are precisely positioned with respect to one another in order to minimize, at a given distance from the optical member, the cross-section of a beam from the fibre which has been transformed by the optical member. The collimator also has a support which can be fitted into the recess so that holder can be adapted to the support, so that it can control the direction of the beam from the fibre which has been transformed by the optical member.

Abstract: A split tank closure and diaphragm assembly for a hydropneumatic filament wound pressure vessel is disclosed. The assembly includes first and second cup shaped plastic tank liners having oblate ellipsoidal end portions and cylindrical sidewall portions terminating in cylindrical open mouth portions.

The ring has a cylindrical outer surface corresponding to the outside diameter of the cylindrical sidewall portions of the liners. The liners form a dovetail joint with the ring and respectively trap an O-ring and a bulbous portion of the diaphragm between recessed portions of the liner and a surface of the ring to seal the interior of the tank. The assembly is wound with a resin impregnated continuous roving to reinforce the tank and resist internal pressures.

Abstract: Honeycomb floor panels for use in elevated floors or the like are disclosed. The honeycomb structure provides similar metal strips providing lateral cuts along one edge providing angulated tabs. The angulation of the tabs provides an angulated throat having a width substantially greater than the thickness of the strips so that the strips can be assembled in an interfitting relationship while the strips of the two arrays are angulated with respect to each other. After assembly, the arrays are moved to a substantially perpendicular position, and in such position a tight fitting relationship is achieved to eliminate looseness. Such honeycomb is provided, in accordance with one embodiment, with upper and lower metal sheets which are welded or otherwise fastened to the honeycomb itself. In such embodiment, an additional upper surface sheet is provided to prevent denting and to distribute concentrated loads to prevent crushing of the honeycomb. Sound deadening is provided between the two upper sheets.

Abstract: A wedge structure for log splitters is disclosed which provides a relatively thin, elongated knife at the forward end. Extending back from the knife is a first spreader providing side walls which diverge at a substantial angle. Extending rearwardly from the first spreader is a second spreader, again providing walls which diverge at a relatively large angle which is substantially greater than the angle of divergence of the first spreader. The two spreaders have a height less than the height of the knife. Secured to the upper edge of the two spreaders is a triangle-shaped plate providing diverging edges which extend laterally beyond the side edges of the spreaders to resist lifting of a log being split. The plate also ties together the upper sides of the two spreaders.

Abstract: A fiber optics condition sensor and a method of producing such a device is disclosed. A bundle of optical fibers provides a planar termination on one end and is bifurcated to provide one group adapted to be connected to a light source and another group adapted to be connected to a detector. A shallow, curved, thin metallic diaphragm provides a central portion movable toward and away from the termination in response to the condition being sensed in order to vary the light reflected to the detector and therefore produce a detector output signal which is a function of the changes in conditions being sensed. The diaphragm may be formed of bimetal for sensing temperature conditions, or of a homogeneous metal to sense pressure.

Abstract: A double-feed prevention device in paper feeding apparatus is provided with a paper feeding roller and a frictional member carried on a paper separating plate mounted on an end of a spring-biased swingable lever.

Abstract: A tube coupling with only a body and a threaded member is disclosed, the threaded member usually being a nut to overlie an outer sleeve and an inner sleeve unitary with the body. These two sleeves define therebetween an annular groove to receive the end of the tube. The method of tightening the nut onto the body provides that a generally conical cam surface on the nut interacts with a shallower taper conical cam follower surface on the outer sleeve to force this cam follower surface radially inwardly and longitudinally inwardly forming annular radially inward bulges on the outer and inner sleeves and on the tube trapped therebetween. This interlocks the tube with the coupling, and provides a fluid seal at three different places, the inner wall of the tube, the outer wall of the tube, and the end of the tube at the bottom of the groove.

Abstract: A method of making a bimetal electrode for spark plugs on a single progressive header starts with a cylindrical bimetal blank having a diameter substantially equal to that of the finished electrode, with a core of high temperature-resistant metal and an outer layer of highly thermally conductive material, with the outer layer comprising substantially one-third of the material of the blank. In progressive operations, the blank is coned and then headed to a diameter so that the core at the headed portion has a diameter greater than that of the blank. A shearing operation then shears the outer portion of the headed portion and the thermally conductive material away to leave an end for the firing tip having a diameter equal to that of the rest of the blank but consisting essentially of the temperature-resistant core material.

Abstract: An assembly machine is disclosed in which a slug of one metal is inserted and staked in a cup formed of another metal. During the staking operation, the shape of the slug and the cup is altered by forming loads thereon. Cups are fed to an assembly position through a plurality of feed chutes which supply the cups to a shuttle. The shuttle operates to alternately receive cups from one feed chute and then the other and to position such cups at an assembly position. A cutter cuts slugs from wire stock and delivers the slugs to the assembly position, where the slugs are inserted in the cups and staked in place. The shuttle operates at a cyclic speed equal to one-half the cyclic speed of the cutter so that the total output of the apparatus is substantially higher than the cyclic operating speed of the shuttle. A combined stock gauge and staking tool is carried by the cutter and the cutter forcibly removes the assembled cup and slug from the assembly position.
