Abstract: Door Guards are shielded from outside access with hand tools while in the open guarded position. The shields close off the opening space between the door and the jam and can be shaped to provide no leverage positions or grasping surfaces which can be used for destruction and release of the guard or opening of the door.

Abstract: An improved deadbolt doorlock bolt assembly has a squeeze-operated "U"-shaped bolt in a channel and may be combined with a receiver assembly. The lock may include an elongated guard with an elongated hook, the guard being hinge mounted on either assembly. When the guard is set, it limits opening of the door to just enough for identification purposes.

Abstract: A device for tensioning and locking an attachable subject which includes, in combination, a toggle clamp and a quick release pin channel lock. The channel lock provides a method for securing an anchor on a bow roller.

Abstract: The invention is a device for tensioning and locking an attachable subject comprising in combination a toggle clamp and a snag proof quick release pin channel lock.

Abstract: The invention is a channel-shaped quick release anchor and chain locking device comprising a channel with shouldered sides and a quick-release pin.

Abstract: An anchor handling boom assembly having an elongated boom and a shank guide member. The shank guide member can be channel-locked along the boom or it can be released to rotate to such a position as to enable the shank of the anchor to easily pass over in retrieval or release. Release of the shank guide member can be made to cause a free fall of the anchor.

Abstract: A handling and storage device for a swivel-fluke-type marine anchor comprises an interrelated shank-receiving boom and fluke-receiving guide both being rotatable with parallel axes of rotation. When the shank of the anchor is held in position by the shank-receiving boom, the fluke-receiving guide receives and folds the anchor into an essentially planar position. In a preferred embodiment suitable for overhanging sides and transoms, the axes of rotation of both the shank-receiving boom and the fluke-receiving guide is the same. In another preferred embodiment suitable for vertical or receding sides and transoms the axes are separate but parallel, and the axis of the boom is on a frame which is also rotatable and which holds the boom away from the side or transom when in the receiving position.

Abstract: A handling and storage device for a swivel-fluke-type marine anchor comprises an interrelated shank-receiving boom and fluke channeling member both being rotatable with parallel axes of rotation. When the shank of the anchor is held in position by the shank-receiving boom, the fluke channeling member receives and folds the anchor into an essentially planar position. In a preferred embodiment suitable for vertical or receding sides and transoms the axes are separate but parallel, and the axis of the boom is on a boom support frame which is also rotatable and which holds the boom away from the side or transom when in the receiving position.

Abstract: Heat storage and/or cold storage are essential to effective utilization of solar energy sources, including sun and wind. Efficient auxiliary controlled heat sources are also desirable, if not essential. This invention provides a liquid heat and/or cold storage unit in radiant heat transfer relationship with the living space of a shelter for use with weather-sensitive energy sources or weather-sensitive energy harnessing mechanisms, and it includes an optional controlled heating source within the liquid storage space. Maximum heat and/or cold utilization is insured with minimal losses through transmission of heat outside living spaces. The heat storage unit may be heated or cooled and heat may be provided or withdrawn from the living space via radiation as well as convection and controlled by means of removable insulation in the form of sliding or folding doors or panels and the like.

Abstract: A mechanically air conditioned shelter includes wind deflectors, as part of the outer walls of the shelter, and a series of blades moving about a generally vertical axis, the wind being funneled into working engagement with the blades. In a preferred embodiment, power from the blades is used to compress a fluid which is reversibly distributed to coils located outside of the shelter, and to another within a liquid storage tank, thereby to either heat or cool the liquid in the storage tank. This liquid is used for heating or cooling of the shelter. A sufficient volume of liquid is maintained in the storage tank to keep the shelter cooled or heated during those periods in which there is little or no wind.

Abstract: Heat storage and/or cold storage are essential in air conditioning systems depending upon weather-sensitive energy sources such as solar heat, including sun and wind. Sufficient supplemental heating sub-systems are also desirable if not essential. Liquid heat storage is the preferred method of storing heat or cold. This invention provides a supplemental heating and dual function heat transfer sub-system for a solar heating system which employs a liquid heat storage medium and a heat storage unit. The sub-system includes a heating unit having a combustion area, a first direct heat transfer means for transferring the heat from the combustion area to the liquid heat storage medium, and a second adjustably regulated direct heat transfer means between the liquid heat storage medium and the living space. If there is combustion in the combustion area, the heat storage medium may be heated or the living space may be heated or both.
