Appl. No.:

6/488653

Inventors:

Kenneth H. Raihala - Superior WI

International Classification:

F23L 300

US Classification:

126292

Abstract:

A safety stovepipe damper assembly designed for use with a conventional type stovepipe and damper as used on coal, wood, or waste burning stoves. Provisions are made for presetting the damper to a specific low fire or closed position. A latch is also provided to hold the damper at an open position when desired. A heat activated means of releasing the damper from an open damper position is contained within the safety assembly. When activated by abnormally high stovepipe temperatures, the damper returns by gravity to its preset or closed position. The safety assembly can be used on vertically or horizontally installed stovepipe and damper assemblies in all sizes.

US Classification:

55480

Abstract:

A filter assembly for a coolant air stream flowing through an LRU box has a base frame with a large opening superimposed on the perforated top surface of the box. A filter element is superimposed over the opening and a cover having a large opening is hinged to the base frame and latched thereto with its opening aligned with the other opening. The filter assembly is clamped by means of a harness to the LRU box with a clamping band that wraps around one end of the LRU box and one end portion of the base frame simultaneously. Spring tensioned cable sections attach to the band and extend diagonally along the sides of the LRU box and then through eyelets on the opposite end portion of the base frame so the cable develops a vertical component of force for clamping the assembly to the LRU box.

International Classification:

A01K 47/06

Abstract:

A wind shield supported by a beehive bottom board prevents directly impinging wind from creating high-pressure differences across the beehive such as promote excessive ventilation. By providing an entry path that opens upward and follows a twisted path, proper ventilation and access to the beehive by the bees may be maintained. The wind shield may be quickly installed on a variety of beehive designs and easily removed during warm weather.

Inventors:

Kenneth Raihala - Superior WI, US

International Classification:

A45B 9/04

US Classification:

135 66

Abstract:

An improved cane, crutch or walking stick tip that allows a user to retrieve objects from a walking surface in a sitting or a standing position without need of bending over. The device employs a single moveable element contained within the tip and can be actuated by the users hand or foot. This improved tip may be furnished on new canes, crutches and walking sticks or as a replacement tip on existing canes, crutches or walking sticks regardless of their design or material of construction. The tip is similar in appearance to existing tips presently in use and does not create a tripping hazard.
