Mechanism for covering a greenhouse has rotating shaft upon which a flexible cover is wound. The shaft travels along an arch or bow truss with the cover being wound upon or released from the shaft to uncover or cover the greenhouse. Two rotating shafts are provided on opposite sides of the roof ridge and each are attached to two sets of cables. One set of cables serving to pull the covers and a second set serving to apply tension to the covers during the covering and uncovering process. A counter weight or spring anchored to the floor is used with the second set of cables to assure adequate tension is applied to the covers.

Abstract:
An energy conducting cable loop enclosure which receives and retains an above-ground loop of a flexible conductor cable in an underground energy distribution system, particularly in a system for the supplying of electrical energy. The main body structure, which is upright in normal placement, is of elongate rectangular shape with an above-ground and a below-ground portion and having an open bottom and a closed top. At the junction of these two portions, supporting feet are located which bridge a hole in the ground, in which the below-ground portion is inserted, to rest on the surrounding ground. A removable front plate provides access to the interior of the above-ground portion. The above-ground portion contains a cable hoop having a radius at least as great as the minimum allowable bending radius of the cable on which a loop of cable is trained after being led through the open bottom and out through the open above-ground front. The depth of the hoop is substantially equal to the depth of the body structure so that the cable loop is captured on the hoop when the front plate is secured in place. The structure is held in place by the anchoring effect of the buried cable by way of the captured cable loop.

Abstract:
The attachment device is made of two piece separable construction for use in securing flexible films and fabrics, hereafter referred to as material. One element has two longitudinal grooves facing in opposite directions, one groove being larger than the other groove. The other element has two longitudinal beads that positively interlock with the grooves of the first element when the two elements are pushed together by one of said beads and the larger groove acting as a pivot and the other bead and smaller groove being engageable by relative rotational movement of said elements about said pivot. Flexing of one or both elements allows for engagement of the shallower groove and complementary bead. The said interlocking action of the two elements is utilized to capture and secure material placed between the two elements. The shallower groove and complementary bead are disengageable by relative rotational movement of the two elements about said pivot when the two elements are pulled apart.
A mechanism for covering and uncovering a cold frame includes a starting base and a spaced-apart terminal base, a frame, and a cover deployable over the frame starting at the starting base and ending at the terminal base. The cover is wrapped from its midline around a cover shaft rotated by a first drive motor, as cables, attached to the leading edge of the cover, pull it over the frame. Those cables are simultaneously winding themselves around a cable shaft rotated by a second drive motor so that cover remains tight between the cable shaft and the cover shaft. The other end of the cables is secured to the starting base while the trailing edge of the cover is secured to the terminal base. Torque arms extend from the first and second drive motors and their distal ends are pivotally connected.
