A goalpost comprises a frame 10 on which is located a net 38. The frame 10 is movable between an assembled position as shown and a folded position, and comprises six lengths of tubing 12, 14, 16, 18, 20, 22, each length of tubing having a first end and a second end, the second end of the first length of tubing being connected to the first end of the second length of tubing and so on with the second end of the nth length of tubing being connected to the first end of the first length of tubing to ...

A frame, including a plurality of frame elements 1 and at least one connecting corner element 5 on which the frame elements 1 are mounted in intersected relation, is provided to form a readily accessed enclosure to accommodate therein an article, a glass plate to allow viewing of the article, a backing plate at the rear and an illumination louver. At least one of the frame elements 1 is mounted to the connecting corner element 5 for relative angular movement therebetween, to facilitate easy open...

A frame system for holding a normally flat picture and bending it into a concavo-convex shape for adding a three dimensional effect and/or eye movement effect to its display. This concavo-convex shape can be created by either urging the picture toward a pre-curved transparent plate or placing the picture in a pre-curved holder. In this frame system an arch-shaped void space is provided for housing a complementary three dimensional article and/or reinforced picture supported by magnetic means. A ...

An apparatus, adapted to be attached to a crib having a mattress, includes includes a frame configured to receive and hold an object while allowing the object to be seen, fasteners connected to the frame and adapted to releasably secure the frame to the crib above the mattress, and a depending member connected to the frame and having a length sufficient to extend underneath the mattress from the frame when the frame is secured to the crib by the fasteners.

A frame, including a plurality of frame elements 1 and at least one connecting corner element 5 on which the frame elements 1 are mounted in intersected relation, is provided to form a readily accessed enclosure to accommodate therein an article, a glass plate to allow viewing of the article, a backing plate at the rear and an illumination louver. At least one of the frame elements 1 is mounted to the connecting corner element 5 for relative angular movement therebetween, to facilitate easy open...

A picture frame having a substantially stiff, rectangular, planar transparent sheet with lip members disposed on two rear opposing sides to slideably receive therein the object to be displayed directly behind the transparent sheet and a sheet of magnetic material to be received within said lips directly behind the object to be displayed. The magnetic sheet, when placed against a metallic surface, holds the frame in place by its attraction to such metallic surface.

At least one of the frame elements 1 is mounted to the connecting corner element 5 for relative angular movement therebetween, to facilitate easy open...

An input video signal is fed to a substracter wherein a difference is taken between the input and the output from a frame memory to provide a difference signal, the magnitude of which is controlled by a magnitude adjuster. The controlled output is then fed to a threshold circuit, from which a significant difference signal is derived which has a magnitude above a given level. The significant difference signal is quantized by an encoder into a code having a reduced number of bits as compared with ...

In one embodiment, an adapter frame is provided for use with a power frame to support a tong assembly. When the adapter frame is coupled to the power frame, the load capacity of the power frame is increased, thereby allowing the power frame to be used with larger tongs or tong assemblies such as a riser tong.
