A sheet holder () for holding sheets () comprising a housing () defining first and second side walls (and) spaced apart from each other and defining a slot () therebetween. The first and second side walls (and) also define a bottom aperture () leading into the slot (). A plurality of guiding grooves () are defined in the first side wall () facing the slot (). The guiding grooves () define substantially opposed groove top and bottom ends (and) and extend further away from the second side wall () adjacent the groove top end () than adjacent the groove bottom end (). Holding elements are each at least partially received in a respective one of the guiding grooves () and movable therealong. At least part of the holding elements () remains in the guiding grooves () at all positions therealong.

Sheet holder

The present invention related to a water detector for use in determining the presence of sufficient water in irrigation systems and plant cultures in general. The detector includes a probe and the presence of water in a soil induces modifications in the optical properties of the probe. The optical properties are monitored and used to control the activation or deactivation of the irrigation system, emit a warning signal or provide a reference value of water potential for monitoring purposes.

A stepladder organizing assembly for increasing a surface area of a head step of a stepladder includes a base portion with a top surface and a bottom surface. A peripheral shoulder is integral to and extends away from each of a plurality of sides. A lip is integral to and extends away from an edge of the shoulder in a direction opposite of the top surface. The shoulder has a plurality of channels therethrough. Straps removably secure the base portion to the head step. At least one tray extension, comprising a block, extends a surface area of the head step. The block has a top wall, a bottom wall, a first side wall and a second side wall. A flange extends away from the first wall. A plurality of protruding members extends away from the flange. The protruding members may be removably placed in the channels.

Stepladder organizing assembly

A method and an apparatus for collecting plates from two rows of plates travelling side-by-side on a moving conveyor comprising inverting plates sequentially in one row of plates and merging said two rows of plates by depositing a plate from one row onto a plate in the other row to form a single row of double plates each having an inverted plate, and assembling a single row of said double plates into stacks. The double plates are assembled into stacks preferably by shingling the double plates to assemble a plurality of overlapped double plates, stacking shingled double plates to form horizontal stacks, turning each horizontal stack onto a side or end of the stack to form a vertically-stacked bundle, and rocking the vertically-stacked bundle on the side or end to align the plates on the side or end, rotating the bundle vertically through 90.degree. onto an adjacent end or side, and rocking the bundle on the adjacent end or side to align the plates on the adjacent end or side, whereby the plates form a squared bundle having even sides and ends. In one embodiment the plates are lead alloy battery plate electrodes each having a tab extending from a side edge thereof, the two rows of plates are travelling side-by-side on a first conveyor with the tabs of one row of plates facing the tabs of the other row of plates, the plates in one row of plates are inverted by passing the plates sequentially over an endless belt having an upper moving surface turning from a substantially horizontal plane through about 90.degree. to a substantially vertical plane at a linear speed effective to turn the plates upside down onto a second conveyor, and the two rows of plates are merged by transferring one row of plates onto a diagonal conveyor intersecting the second conveyor and controlling the relative speeds of the second conveyor and diagonal conveyor whereby each plate on one conveyor is deposited on a plate of the other conveyor to form a pair of double plates with the tabs of the two plates at least partially overlapping each other.
