International Classification:

G01J 5/02

US Classification:

25033912

Abstract:

A method of identifying different brands of peat moss including the steps of separation of the peat and sand by first adding water to the peat and sand mixture to enable the peat to float to the top of the water and the sand to gravitate to the bottom collecting the peat at the surface of the water and drying the peat there after grinding the peat to pass thru a sieve of small mesh then mixing the ground peat with Potassium Bromide (KBr) at a ratio in the neighborhood of 1:20 then grinding said mixture with a mortar and pestle then loading to a sample cell; then loading a ground pure KBr to a reference cell, then scanning and collecting wave spectrums of the references and samples in the range of 4000 to 600 cm, collect said spectrums directly from said peat/sand mixtures and dry said peat/sand mixtures in the neighborhood of 105 degrees centigrade for a 24 hour period.

US Classification:

111101, 37302

Abstract:

The invention comprises a radio controlled tree planter. The planter has four hydraulically controlled tree spades mounted on vehicle, with hydraulic cylinders to position the spades in a storage, position, a vertical digging position, and a actual digging action. A tv size radio transmitter has button controls for transmitting radio signals to a radio receiver mounted on the planter, which receiver in turn transmits signals to solenoids operating the hydraulic cylinders to thereby control the movement of the spades in the three positions of its operation to thereby control the digging operations of the spades within the range of the receiver from a remote location.

International Classification:

B60P 1/00

US Classification:

29802300R

Abstract:

The invention comprises a dump trailer having a mobile frame for towing behind a powered vehicle. A dump box is pivotally mounted at its rearward end to the mobile frame. The box has a pair of sides and a front wall with a gate pivotally mounted at its upper end to the rear portions of the side wall to pivot outward await from the side walls when the box is tilted upward on the mobile frame about its rear pivotal mounting. Latch means latching the gate to the side walls, with means automatically unlatching the gate from the side walls when the box moves from parallel position upon the mobile frame to an upward tilted position relative to the mobile frame. Supporting wheels are mounted centrally beneath the mobile frame

International Classification:

A01C 15/18

US Classification:

222622

Abstract:

The invention comprises of a two wheeled seed spreader having a centrally located box for storing the seed. The box has surrounding sides and an open bottom. A conveyor belt is mounted across the open bottom for conveying seed in the box forward to the front bottom of the box, an adjustable brush is mounted above the forward end of the conveyor and adjustable downward against the belt to vary the amount of seed conveyed off the forward end of the belt. A rotary brush is mounted just in front of the forward end of the belt and driven counterclockwise and downward against the belt to drive seed traveling off the forward end of the belt downward toward the ground.

US Classification:

298 14

Abstract:

The invention comprises a dump trailer for dispensing materials onto receiving objects from different heights comprising a box and main frame with the box tiltable to raise one end of the box at an angle to the main frame. The box has a first and second conveyor with the first conveyor powered to travel along the bottom of the box towards the one end of the box to convey material in the box towards the one end of the box when the box is tiltable at an angle. The second conveyor is raisable with the box at the one end of the box with means to maintain the second conveyor parallel to the main frame and generally parallel to the ground.

Abstract:

The invention comprises a seed spreader having a cylindrical drum mounted upon a pair of wheels for traviling the drum along the wheels for distributing seed along path upon the ground. The drum rotates with the wheels as the wheels rotate along the ground as an operator pushes the wheels forward by a handle mounted to the drum. The drum is hollow and has a door which can be opened to enable seed to be deposited into the interior of the drum. The drum has a plurality of holes about its exterior so that seed can travel out the the holes onto the ground as the drum is rotated as the wheels travel along the ground

International Classification:

B60P 136

US Classification:

414504

Abstract:

The invention is directed to a mobile bin device having a mobile bin with a first conveyor extending along the bottom of the bin beneath a bin opening to convey material in the bin to one end of the bin. A second belt conveyor has one end pivotally mounted to the one end of the bin to pivot relative to the bin upward and downward and to one side or the other. The second conveyor is slidably mounted in its pivotal mounting to side longitudinally in the mounting to along the one end of the bin beneath the one end of the first conveyor to shorten or lengthen the distance from the outer end of the first conveyor to the outlet end of the second conveyor at the one end of the bin. Power devices are provided to power the upward and downward movement of the second conveyor and the longitudinal movement of the second conveyor.
