  • Patent number: 4848590
    Abstract: Apparatus for sorting pieces of non-ferrous scrap metal into a plurality of components, each component being a particular metal type, feeds the pieces into a vertically disposed sorting zone. The pieces fall down a steeply inclined guide member under the influence of gravity and they pass a pair of timing devices which are spaced apart along the guide member, each timing device being a light source on one side of the path of the pieces and a light detector on the other side. The timing devices provide signals representing not only timing but also size an velocity. The pieces then pass an x-ray analysis system including a source of high energy rays to induce x-ray fluorescence and a detector to detect this fluorescence. The detector provides signals indicating the metal type for each piece of scrap. The pieces then fall past a plurality of blast nozzles spaced apart along the guide member.

  • Patent number: 4848240
    Abstract: An improved tool for railway track adjustment machines is disclosed which may be made by processes forging, casting, and which includes a shaft and a blade manufactured as separate entities and force-fitted together. In making the tool the lower end of the shaft is formed so that it is able to be forced between flanges located on the rear side of the blade. This lower end preferably has a transverse cross section shaped as a trapezoid with an apex angle .gamma. and is upwardly and outwardly tapered at an angle .alpha.. The flanges located on the rear side of the blade are manufactured from the same piece of material as the blade and define a slot which opens upwardly and outwardly at an angle to the direction of the longitudinal axis of the tool and the symmetrical plane of the blade. A method the slot defined between the flanges has a transverse cross section which tapers inwardly at an angle .delta. and may be formed by deforming the blade.

  • Patent number: 4846073
    Abstract: Self propelled pallet vehicles (12a) are guided along a track network (10) by downwardly projecting guide pins (350, 352) carried by each pallet vehicle (12) which engage slots (354, 358) in the track network and steer the pallet vehicle (12) along the track network (10). The track network has main (20) and branch (22) track sections, and selective delivery of the vehicles to various destinations along the track network (10) is achieved by controlling the position of the guide pins (350, 352) between alternate rotated raised and lowered positions. In the lowered position the guide pins (350, 352) interact with the track network (10) to guide the pallet vehicle (12) into a branch section (20) of the track. In the raised position, the guide pins (350, 352) cause continued movement of the vehicle (12) along the main track section (22) and past a junction (38). The guide pin position may be controlled by a photoemitter (364) at the junction (38), or by various other alternatives.

  • Patent number: 4843971
    Abstract: A suspended monorail track system has a box-shaped cross section with flanges extending inward and upward from the bottom edges of the side walls to form an acute angle between each flange and its attached side wall. An opening remains between the flanges extending along the bottom of the track. An intermediate horizontal wall may be added below the top wall to form an enclosed channel for power and signal cables within the track. A number of power and signal conductors extend along the interior surfaces of the track to provide electrical contact with vehicles moving along the track. Signal conductors are used to prevent collision between vehicles. Each vehicle is suspended from the track by a bogie assembly extending through the opening along the bottom of the track. The bogie assembly is supported by load-bearing wheels riding on the upper surfaces of the flanges, and stabilized by a second set of wheels rolling along the bottom surfaces of the flanges.

  • Patent number: 4842147
    Abstract: The apparatus is used for detecting the proper conductivity of a conductive film enclosed within a nonconductive substrate or envelope such as a fluorescent lamp without requiring physical contact with the fluorescent lamp. The conductive film detector comprises a capactive proximity switch mounted close to but spaced from the lamp as the lamp passes the inspection station. At the inspection station there is also provided a feeler switch for sensing lamp presence and a cam switch for inspection initiation when the lamp is instantaneously properly positioned. A control unit powers the capacitive proximity switch and receives the proximity switch output to control a lamp rejection mechanism for rejecting lamps having resistance that is too high. The set up procedure involved adjustment of the capacitive proximity switch sensitivity by using test lamps of alternately acceptable resistance and unacceptable resistance, along with adjustment of lamp-to-proximity switch spacing.
