  • Patent number: 6571903
    Abstract: A suspension for a heavy duty vehicle is provided that includes a frame. A lower linkage is supported by the frame at a first pivotal connection. A drive axle assembly is supported by a lower linkage at a second pivotal connection. The drive axle assembly includes an input shaft defining a pinion angle. An upper linkage interconnects the drive axle assembly and the frame at third and fourth pivotal connections, respectively. The upper linkage includes an adjustment member, such as a turnbuckle, for modifying the length of the upper linkage to obtain a predetermined pinion angle. In this manner, the pinion angle may be adjusted upon assembly of the suspension system. Furthermore, by permitting the drive axle assembly to pivotally move relative to the linkages, the pinion angle may be maintained during suspension movement.

  • Patent number: 4998272
    Abstract: A personal voice mail system adapted to be connected to a standard touch tone telephone. This system would allow a subscriber to prerecord a message to be delivered to one or more called parties at a particular time. Additionally, the system can be made secure by requiring the called party to provide a confidential code before the message is relayed.

  • Patent number: 4181503
    Abstract: In the hydrotreating and steam reforming of an oxygen and sulfur bearing hydrocarbon fuel the oxygen is first removed in an oxidizer containing a bed of platinum catalyst, the inlet temperature being well below 1000.degree. F. and preferably on the order of 300.degree. F. The sulfur in the fuel does not harm the oxidizer catalyst and may be removed downstream by known hydrodesulfurization techniques prior to reforming.
