Abstract: A fruit ripening system wherein a continuous inflow of fresh air and ethylene gas is provided into a fruit ripening chamber in correct proportions to form a fruit ripening gas mixture that will predictably ripen fruit in a very short period of time, regardless of the previous state of ripening of the fruit. At the same time, the ripening chamber is continuously purged of carbon dioxide that is a byproduct of the ripening process so that during the ripening process a concentration of carbon dioxide sufficient to materially impede the ripening process is never allowed to build up. Critical parameters are defined for ripening temperature, the minimum ethylene gas concentration, time of exposure to the ethylene gas, and purging of carbon dioxide.

Abstract: A wheeled strike-off apparatus is movable over a surface of uncured concrete or subgrade materials and is operable to establish a desired grade of the uncured concrete surface or subgrade surface. The apparatus includes a wheeled support and a plow assembly. The plow assembly may be adjustably mounted to a front frame portion and may be vertically adjustable relative to the frame portion. The plow assembly may include a plow member for engaging and establishing the desired grade and/or may include a vibrating member for vibrating and smoothing the concrete after the plow member establishes the desired grade. The apparatus may include a user input that is adjustable by an operator to adjust a down pressure of the plow assembly at the concrete when the wheeled support is moved in a rearward direction.

Abstract: A screeding apparatus and method for screeding and smoothing an uncured concrete surface includes a vibrating member and a grade setting device adjustably mounted to said vibrating member. The screeding apparatus may include a wheeled support which at least partially supports the vibrating member and/or the grade setting device. The grade setting device may be vertically adjustable to set or indicate the desired grade of the concrete surface as the screeding apparatus is moved over and through the uncured concrete. The level of the screeding apparatus may be automatically adjustable to maintain a desired level and angle of attack of the vibrating member.

Abstract: A wheeled strike-off apparatus is movable over a surface of uncured concrete or subgrade materials and is operable to establish a desired grade of the uncured concrete surface or subgrade surface. The apparatus includes a wheeled support and a plow assembly. The wheeled support may have a front frame portion and a pair of front wheels rotatably mounted at the front frame portion, and may have a rear frame portion and a pair of rear wheels rotatably mounted at the rear frame portion. The plow assembly may be adjustably mounted to the front frame portion and may be vertically adjustable relative to the frame portion via an actuator. The plow assembly includes at least one plow member for engaging and establishing the desired grade.

Abstract: A screeding apparatus for screeding and smoothing an uncured concrete surface includes a vibrating member and a grade setting device adjustably mounted to said vibrating member. The screeding apparatus may include a wheeled support which at least partially supports the vibrating member and/or the grade setting device. The grade setting device is vertically adjustable, such as via a laser plane responsive control system, to set or indicate the desired grade of the concrete surface as the screeding apparatus is moved over and through the uncured concrete. The level of the screeding apparatus may be automatically adjustable to maintain a desired level and angle of attack of the vibrating member. The vibrating member may be activated only when the screeding apparatus is moved in a screeding direction so as to reduce depressions that otherwise may occur if the vibrating member vibrates on the uncured concrete when not moving.

Abstract: A device and method for measuring an initial camber of a beam includes a support member positionable at a beam of a structure. The support member includes a laser receiver for receiving a laser reference plane at a first location when the support member is positioned at an end of the beam and at a second location when the support member is positioned at a central region of the beam. The initial camber of the beam is then derived by determining a difference between the first and second locations on the laser receiver. A loose shoring system provides an adjustable length support section and a positive stop for limiting deflection of the beam at a desired amount generally equal to the measured initial camber of the beam. The stop is adjustable to set a gap approximately equal to the expected deflection or initial camber of the beam as desired.
