A universal visual shield apparatus, for use with a hockey helmet, is usable for training hockey players by partially blocking a user's field of vision. The apparatus includes a main shield body formed from an elastically deformable material, and is attachable to the helmet using connectors. The main shield body includes a horizontal floor portion and a vertical edge portion that cooperate to block a user from seeing the puck while it is in the user's possession, while still allowing the user to see forward. When worn, the apparatus forces the user to look forward, beyond the puck and stick. The apparatus may include adjustable apparatus straps, and can be used on any sized helmet without modifying the helmet or the apparatus. Because the apparatus is soft and crushable, the apparatus will not harm the user or another player if they are involved in a collision on the ice.

High-powered antenna installations employable in rotatable electrical systems for the transmission and reception of electromagnetic energy and, more particularly, an integral radome-antenna structure which is mounted for rotation on the exterior of an aircraft. The rotatable radome-antenna structure which is adapted to be mounted on aircraft, or possible on other suitable support installations, will prevent excessive electrical power losses encountered in present day structures, particularly inasmuch as the essential components, such as the antenna signal receiving and transmitting devices, power generating structure and air turbines, including cooling conduits for circulating coolant to and from the various components are mounted on the rotatable structure of the system, such as an equipment rack and shelf structure, so as to be rotated in conjunction with the radome-antenna structure.

A quick connect/disconnect assembly includes a headed bifurcated primary member or post having a secondary or locking means releasably, slidably and swingably related thereto for movements between locked and unlocked positions.

Toothbrush

The handle of the toothbrush has a bifurcated forward end. The spaced free outer ends of the bifurcations are interconnected by a transversely extending arched head defining opposite lower side walls and an upper middle wall therebetween. Tufts of bristles project inwardly from the inner wall of the head. The tufts project from the opposite side walls at an angle to the horizontal center line of the head and the tufts projecting from the middle wall point toward the center point of the head.
