Abstract: A rigging arrangement and yarder are disclosed for yarding in which a single cable is used. This cable is anchored at a main storage drum on a yarder and preferably at an anchor in the vicinity of the tail block. The single line serves as a running skyline for supporting a carriage and includes several loops around a tram drum and an idler drum (but only one layer on said drums) which operate to hold cable or to reel equal amounts of cable in or out to both the yarder side and the anchor side of the carriage to move the carriage without introducing slack into either side. Since only a single layer of cable is wound on the tram and idler drums, no energy is lost dealing with varying speeds and torques caused by changing effective diameters, thus saving energy and weight of equipment.

Abstract: A magazine of a nailer gun organizes nails with the head of each nail in sliding contact with parallel support rails and the point of each nail on a support track that parallels the rails. The rails and track orient the nails so that they are parallel to each other and at an acute angle to the perpendicular between the rails and track. In this orientation the head of each nail overlaps the head of the nail preceding it and contacts the shaft of the nail following it. At a driver head of the gun, the distance between the point support track and the rails lengthens and the nails rotate for alignment with the axis of a chamber of the driver head. Upon reaching the chamber, each nail drops a short distance onto a dog and is retained in place by the dog. A driver of the gun impacts the nail in the chamber and drives it. The dog swings out of the way in response to the impact of the driver. A nail guide rotates and slides away from the chamber upon being engaged by a bent nail.

Abstract: An elongated burner for producing a stream of metal oxide soot comprises a burner face having two parallel arrays of orifices for issuing a gas-oxygen mixture to produce two intersecting linear flames. Disposed between the gas-oxygen orifices is an array of orifices for issuing metal halide vapor into the flame. Two parallel arrays of orifices, one on each side of the vapor orifices and closely spaced therewith provide high velocity jets of inner shield gas on opposite sides of the vapor streams. Disposed between the inner shield gas orifices and the gas-oxygen orifices are two elongated slots which are much greater in width than the diameters of the aforementioned orifices. These slots provide a large volume, low pressure dry, nonreactive gas which prevents the flame from "backsplashing" onto the region of the vapor orifices and further prevents the deposition of soot on the burner face.

Abstract: An injection nozzle for injection moulding purposes has a nozzle body with a feed passage opening which is normally closed by a needle valve.

Abstract: An improved hammer design for a swing-hammer type crushing machine. The hammer is in at least two pieces, a shank and a detachable tip section. The shank is pivotably mounted at one end on a rod extending between a pair of radial discs spaced along the machine rotor. The tip section is joined to the shank by a simple connecting pin which passes through co-aligned holes in a bifurcation on the tip and a lug extending outwardly from the shank. Spaced apart tabs at the free end of the shank co-operate with a stop on the rotor to limit the pivotal movement of the hammer between predetermined limits such that the connecting pin is always confined between the pair of rotor discs during operation of the machine. However, a worn or damaged tip section can be readily replaced in situ by removing the rotor stop, pivoting the hammer so the connection between the shank and tip are outside the rotor, and removing the connecting pin.
