A pipelined CPU executing instructions of variable length, and referencing memory using various data widths. A writeback cache is used (instead of writethrough) in a hierarchical cache arrangement, and writeback is allowed to proceed even though other accesses are suppressed due to queues being full. Separate queues are provided for the return data from memory and cache invalidates, yet the order or bus transactions is maintained by a pointer arrangement. The bus protocol used by the CPU to communicate with the system bus is of the pended type, with transactions on the bus identified by an ID field specifying the originator, and arbitration for bus grant goes one simultaneously with address/data transactions on the bus.

A mudflap assembly comprising a bracket for connection to a vehicle and a hanger extended therefrom. A mudflap is connected to one end of the hanger, while the bracket rotatable receives the other end and maintains the hanger in an initial resting position until the hanger is acted upon by a sufficient horizontal force. A bulge or detent on the bracket resists horizontal movement of the hanger.

A mudflap assembly comprising a bracket for connection to a vehicle and a swiveling support is claimed. A mudflap support bar is connected to an upper end of the swiveling support for supporting a mudflap. The bracket rotatably receives the free lower end of the swiveling support hanger and maintains the mudflap support bar in an initial resting position until the support bar is acted upon by a horizontal force. A spring installed on the free lower end of the swiveling support hanger provides compressive force against the bracket.

An improved gantry for an examination apparatus, such as an x-ray apparatus comprising a source of x-rays and a detector of fluoresced photons, is disclosed. The apparatus is particularly suitable for use in a vehicle such that the examination can be carried out at locations convenient to the patients. The apparatus comprises a vertical standard and first and second carriages. The first carriage is movable along the vertical standard and carries a horizontal arm. The horizontal arm carries the second carriage, which moves along the horizontal arm in a direction orthogonal to the axis of the standard. A transverse arm carrying the x-ray apparatus is carried by the second carriage and moves with respect thereto in a third direction orthogonal to the first and second directions, so that three directions of motion along orthogonal axes are thus provided. Additionally, the second carriage is rotatable about the horizontal arm providing a first direction of rotation. The x-ray apparatus is mounted on a support plate which is pivotable with respect to the transverse arm, providing a second degree of rotation. Caging arms are provided which extend from the frame of the vehicle directly to the support plate and are readily fixed thereto, to confine the support table and the associated x-ray apparatus in transit. The caging arms and the standard are shock mounted to the vehicle such that any vibration occurring during travel is damped out.

A mudflap retainer comprising two halves wherein each half has protrusions to extend through the standard hole placements of the mudflap. The halves are mated together through the mudflap creating a wedge at the top of the mudflap. The mudflap can then be inserted through a slot in a mudflap hanger assembly wherein the wedge created by the retainer couples with the mudflap hanger assembly.

A vehicular firefighting system includes a vehicle, a boom pivotally coupled to the vehicle about a horizontal axis and a nozzle pivotally coupled to the boom. In one embodiment, the system includes a linkage having a first end coupled to the nozzle and a second end coupled to the vehicle such that the linkage maintains an orientation of the nozzle as the boom pivots about the horizontal axis. In another embodiment, the boom forms at least one fluid conduit in fluid communication with the nozzle so as to deliver firefighting agent to the nozzle.
摘要:
An aerial boom assembly comprising a first member having a fixed length and comprising first and second ends, the second end being pivotally coupled to a mobile base. The aerial boom assembly comprises a second member pivotally coupled to the first member at the first end, the second member comprising an extension member slidably coupled to the second member along an inner channel of the second member. The first and second members are made from a composite material comprising a reinforcement material in a polymeric matrix.
