A broadcast feeder for projecting food aggregate or pellets directionally into an area up to, for example, sixty or more feet away from the feed container. The action is controlled to provide a predetermined quantity of aggregate at a predetermined time. The velocity of the feed as it exits the feeder is such that the area directly surrounding the feeder is free of feed particulate. A modular design affords the ability to operate as a self-contained unit with its own storage hopper or as a retrofit module added to existing conventional barrel type scatter type feeders. The projection of the feed is accomplished by propelling the feed pellets with a center intake centrifugal air blower assembly designed such that no special feed gates, baffles or chutes are required.

The present invention provides a drive device for a working vehicle whereby gear change shock during the forward / reverse running changeover action can be reduced while achieving shortening of cycle time and protecting various clutch mechanisms in the transmission. If a reverse running command is output from a running control device while the vehicle is running forward, an ECMV controls a braking force of a brake device so as to reduce a vehicle speed through a first prescribed speed to a second prescribed speed, and disengages the forward clutch. When the vehicle speed reaches the first prescribed speed, the ECMV puts the reverse clutch in a slipping action condition and, after the vehicle speed reaches the second prescribed speed, gradually engages the reverse clutch.

A shrouded outdrive propels a high-speed boat having a hull for high-speed passage through water. The hull has at least one bow at the forward end and at least one transom at the stern. A tubular shaft extends at a small angle (6° to 12°) from the boat transom into the water, and a drive shaft is arranged within the tubular shaft. A propeller is mounted to the drive shaft for partial immersion in the water so that a lower portion of the propeller extends into the water during high-speed floating passage of the boat and a upper portion of the propeller is above the water during high-speed floating passage of the boat. A shroud is arranged about the propeller and is disposed below the water and adjacent the propeller. A mount holds the shroud to form a shroud-enclosed channel during high-speed passage of the boat through the water in which the propeller rotates. A plate horizontal to the undisturbed passing water surface overlies the departure side of the propeller at a radial distance of about two thirds (⅔) of the radius of the propeller. This plate immediately abuts the departure blading of the propeller in the direction of boat movement through the water and assures immersion of the lower pitch departure side of the partially immersed propeller in water for more efficient propulsion. Embodiments are disclosed where the plate is utilized as the necessary support for the shroud. Additionally, both the shroud and the plate can have small angular variations with respect to the surface of the undisturbed surface through which the high-speed hull passes.

An electronic cam using a servo motor is controlled such that its motion including its acceleration will be connected between synchronized and non-synchronized control sections. A controlled object is moved at a fixed speed during the synchronized control section. A fifth-order function for position control of the electronic cam, a fourth-order function for speed control of the electronic cam and a third-order function for acceleration control of the electronic cam are used in the non-synchronized control section such that operation of the electronic cam at transition points between the synchronized control section and the non-synchronized control section is smoothly controlled.

A refrigerator and / or freezer with an appliance carcass, can be closed by at least one door, and a powered door operating device for automatically operating the door. The door operating device has drives both automatically opening and closing the door.

The invention refers to a self-propelled working machine comprising ground engaging means that are in drive connection with an engine for propelling the working machine, a desired speed input means having a range of movement for inputting a desired speed, a control unit receiving a desired speed signal from the desired speed input means and controlling an actuator that is influencing the speed of the ground engaging means based upon the desired speed signal.
