  • Publication number: 20240080594
    Abstract: A speaker can have a main body with a generally spheroidal shape, which can be supported standing on its end. The speaker can include a subwoofer that faces forward. A plurality of mid-range drivers can be distributed around the sub-woofer, facing generally forward and radially outward. A plurality of tweeters can be distributed around the sub-woofer, facing generally forward and generally outward. The outer housing portion of the speaker can be covered with a fabric material. A user interface ring 162 can be touch sensitive to receive input, and can have a plurality of lights that can be illuminated separately to convey information to the user.

  • Patent number: 5170614
    Abstract: A harvester adapted for harvesting low-lying fruit, such as typical with high-density, dwarf trees, includes an intra-loop conveyor for collecting detached fruit relatively close to the ground and elevating same with a single flighted belt. The harvester straddles a single row of the trees and detaches the fruit therefrom by repeatedly impacting the tree canopies are the harvester moves along the row. Spring-loaded deflection plates close around the tree trunks and deflect detached fruit outwardly to interior surfaces of a pair of single-loop conveyors. Baffles cooperating with the interior of each conveyor restrains fruit therein as the conveyor passes overhead to an inverted position. Fruit is discharged from the conveyor elevated segment onto an output conveyor passing beneath the discharge area. The output conveyor includes a multi-segment, foldable conveyor frame over which a single conveyor belt is entrained. The conveyor belt may be folded over the harvester during non-harvesting transport.

  • Patent number: 5092422
    Abstract: A multipurpose horticultural crop tractor combines certain clearance and versatile implement mounting features for accommodating a wide variety of alternative field production operations. A movable operator station provides full bidirectional operator control. An operator station may also be suspended on a boom pivotably mounted to the tractor frame for repositioning of the operator station about such frame. The implement mounting system also permits alternate high or low clearance mounting of a conventional three-point hitch, which when used in an elevated position enables attachment of high crop harvesting heads. Alternative implement mounts permit simultaneous usage of two separate implements. The tractor may be outfitted for many alternative functions, such as tillagae, planting, cultivating, spraying, harvesting, materials handling, and irrigating missions, including usage of a vertically movable lift unit with horizontally adjustable lift arms.

  • Patent number: 4629005
    Abstract: A harvester for bulb, root and leafy vegetable products including stationary blades (31, 32), rotatable discs (131, 132) or the like which are transported at an angle through opposite sides of a product plant bed to loosen the soil, cut the root system, and prepare the products for removal from the plant bed; a pair of opposing, rotatable belts (51, 51') which follow an inclined path and cooperate to define a product passageway therebetween, said belts (51, 51') defining a product lifting and transport section (41) in which adjustable, pressure pulleys (48, 48') ensure proper gripping pressure on the products, and a product orienting section (42) in which the products are transformed from a vertical to a horizontal disposition; support means (70) adjacent said product orienting section (42) for receiving tops of products oriented to a horizontal disposition; and conveyor means (75) adjacent an end of said product passageway for receiving freed, horizontally disposed product.

  • Patent number: 3967539
    Abstract: An adjustable stroke length fluid cylinder used to move agricultural or industrial machinery is disclosed. The cylinder is an enclosed unit having a movable piston therein which is attached to an axial piston rod secured to the load. A fluid valve directs the application of pressure fluid to either side of the piston to extend or retract the piston rod. One end of the cylinder houses a head unit containing an internal valve which is operated by a stop member positioned on the piston rod. The internal valve is effective to stop retraction of the piston rod when actuated by the stop member by blocking fluid flow through the cylinder. Subsequent extension of the piston rod automatically returns the internal valve to its open position.
