Abstract: Picture frame components include frame sections each having a channel and communicating cavity that are open at the rear of the frame. At least a region of each frame section adjacent the cavity is deformable and defines a deformable bearing surface. At each frame corner a bracket is provided to hold two adjoining frame sections together. The bracket has two legs with an engaging member on each leg that presents an engaging wall for being received in the frame section cavity and for engaging the deformable region of the frame section. Either the engaging wall or bearing surface, or both, are angled relative to the frame section length. The bracket is inserted in the channels of the adjoining frame sections and each frame section bearing surface is deformed by the engaging wall as the frame sections are forced tightly together.

Abstract: A kit for making a three-dimensional picture includes a frame encircling a three-dimensional window into which may be inserted a plurality of substantially planar decorated scenes. The depth of a scene in the window in determined by bending backward resilient hinges carried at the edges of the scene.

Abstract: The elongated ovoid body of the lure has the appearance of a small baitfish. Within the body is a longitudinal flow passage with a diverging nozzle at the egress portion thereof which produces effects on the body, similar to the actions of the caudal fins of the baitfish. The ingress portion of the passage gently converges to a cylindrical throat portion which terminates a a concave shaped baffle. The baffle directs the flow of water in the passage into the entrance portion of the nozzle through which the water is discharged from the body. The nozzle, which is oblique to the axis of the body, is of the form of diverging triangular discharge nozzle. The anterior portion of the body, shaped in the form of a leading scoop, causes the lure to dive when towed through the water. When being towed through the water, the lure swims with excitable side to side darting movements, thereby resembling an injured or otherwise excited fish.

Abstract: By means of winder gearing maintaining essentially constant the winding speed a drive motor drives a winding mandril. Operatively associated with the winding mandril is a winding band which is paid-off of a freely rotatable supply roll. Engaging at this supply roll is a jaw brake. The winding or wind-up band is guided over a balance or rocker arm which is upwardly and downwardly pivotable about a pivot axis. By means of a contact or pressing mechanism the balance arm is pressed against the winding mandril. The imbricated printed product stream, infed from a band conveyor, arrives at the balance arm or rocker and the winder band and is supported thereat. The thus supported imbricated printed products are infed from below to a winder gap and in conjunction with the winder band wound-up on the winder mandril. The winder band separates the individual wound layers or plies from one another.
