The rotating hitch stop may include at least three flanges configured to abut a cart and may further include a detent mechanism. The cart coupling assembly may include at least a first portion and a second portion. The first portion may be pivotally coupled to the second portion. The first portion may include first and second engagement members. The second portion may include third and fourth engagement members.

Abstract: An apparatus for transporting carts including a machine body, a steering control arranged on the body, a steering pedestal pivotally arranged with respect to the body, and a selection mechanism adapted to be selectively coupleable between the body and the steering pedestal providing for a caster mode and a steering mode respectively. A method of using a dual mode utility machine including depressing a first lever thereby engaging a pivoting selector into a steering pedestal engaging position and controlling the direction of the machine by rotatably manipulating a tiller, and depressing a second lever thereby disengaging the pivoting selector from a steering pedestal engaging position to a body engaging position and controlling the direction of the machine by pushing and/or pulling a machine from side to side via a fixed tiller.

Abstract: The present invention is a device adapted to transport wheelchairs. The device comprises a body, a motor driven wheel coupled to the body, and a hitch mechanism coupled to the body. The hitch mechanism includes a first wheelchair engagement member displaceable relative to rest of the hitch mechanism.

Abstract: The present invention is an improved cart coupler assembly for use on a shopping cart retriever vehicle. The cart coupler assembly provides a means for connecting shopping carts to the cart retriever vehicle. The cart coupler assembly may employ an actuator to move yokes into position to enable the yokes to engage shopping cart members. The cart coupler assembly may employ the upwardly facing concave surfaces of U-shaped yokes to engage the rear wheels of a shopping cart. In the place of yokes, the cart coupler assembly may utilize a shopping cart emulator that emulates one or more portions or features of a shopping cart in order to facilitate the engagement of the coupler assembly to a shopping cart.

Abstract: The present invention is a dual hitch assembly comprising a framework, a travel surface contacting assembly, and a biasing element. The framework includes a first hitch and a second hitch. The biasing element extends between the framework and the travel surface contacting assembly. The dual hitch assembly allows two wheeled carts to be coupled together in a train-like manner by placing the hitch assembly between the two carts and coupling the first hitch to the first cart and the second hitch to the second cart.

Abstract: The present invention is a hitch assembly for coupling a powered cart mover to a cart, wherein the cart has one of three different types of hitching elements. The hitch assembly comprises a mount and a foot. The mount secures the assembly to the mover and includes a vertically adjustable portion biased in an upward position via a biasing element. The foot is pivotally coupled to the vertically adjustable portion and includes first, second and third attachment features. Each attachment feature is configured to receive one of the three different types of hitching elements.

The hitch mechanism includes a first wheelchair engagement member displaceable relative to rest of the hitch mechanism.

Abstract: The present invention is a shopping cart collection device adapted to engage to first and second shopping carts and capable of pulling a first train of shopping carts extending from the first shopping cart and pushing a second train of shopping carts extending from the second shopping cart. The device comprises a motorized unit comprising a drive wheel, a first hitch and a second hitch. The first hitch is proximate a first side of the motorized unit and is adapted to engage the first shopping cart. The second hitch is proximate a second side of the motorized unit opposite the first side and is adapted to engage the second shopping cart.

Abstract: The present invention is a powered hospital bed mover or bed transfer system. The bed mover includes a bed attachment mechanism that is vertically displaceable relative to a base that includes an electrically powered drive wheel and a pair of support castors. The attachment mechanism includes a pair of horizontally oriented jaws with jaw openings that face away from each other. Each jaw includes a contact switch in its bottom surface and a contact switch in its jaw opening. The contact switches indicate to the mover and its user that the mover is properly engaged with the frame of a hospital bed. The jaws are horizontally displaceable and diverge from each other to engage vertical frame members of a hospital bed. A control panel has a joystick adapted to control the speed and direction of travel for the mover. The control panel also has controls for actuating the jaws, changing the elevation of the attachment mechanism, and locking at least one of the support castors.

Abstract: The present invention is a motorized shopping cart retriever that includes a controller that attenuates the power provided to the drive system of the retriever to prevent the retriever from being utilized to move an excessively heavy load of shopping carts. By preventing the retriever and carts from being subjected to overloaded conditions, the operational lives of the retriever and carts are maximized. The retriever is also provided with a burst mode that allows the power provided to the drive system to rapidly increase past the normal attenuated level for a brief period of time in order to reduce the time required to accelerate a retriever loaded with carts to a terminal velocity.

Abstract: A nozzle and method of use thereof is provided for atomizing a liquid stream. The nozzle is particularly useful for atomizing a hydrocarbon feed into a catalytic cracking zone of a fluidized catalytic cracking (FCC) process. The nozzle includes a primary conduit for receiving a liquid stream and a secondary conduit for receiving a dispersion medium. At least a portion of the secondary conduit is positioned within the primary conduit to form a passageway for the liquid stream between the inner surface of the primary conduit and outer surface of secondary conduit. The dispersion medium and liquid stream are combined in a mixing zone that is located between the outlet of the secondary conduit and the outlet of the primary conduit. In the mixing zone, the primary conduit inner surface is gradually tapered so the cross-sectional area of the primary conduit outlet is decreased relative to the cross-sectional area of the primary conduit inlet.

Abstract: The present invention provides a nozzle, nozzle assembly, and method of use thereof for atomizing a liquid stream into a flat fan-shaped spray. The nozzle and nozzle assembly are particularly useful for atomizing a hydrocarbon feed into a catalytic cracking zone of a fluid catalytic cracking (FCC) process. The nozzle includes a nozzle tip that has at least three substantially vertical openings extending from the inner surface of the nozzle tip to the outer surface of the nozzle tip. The openings are angled from 0 degrees to about 75 degrees. The present invention also provides a nozzle assembly containing at least three nozzles of the present invention that are radially mounted around the perimeter of an area to be sprayed.
