Abstract: A two-level sea-land creeping vehicle formed by three main parts: a frustoconical bow portion which is movable independently but connected to the central part or compartment in the form of a drop of water, which is flat in the lower part and which is fixed with respect to the rear part which comprises the drive and steering assembly, as well as the breathing and safety zone.The vehicle is displaced on land by means of two rollers disposed in the lower region and by the drive of the motor, and it is likewise displaced on the surface of water due to its buoyancy and it is also displaced in a condition of dynamic immersion by the drive of the motor linked to positioning of the bow portion and hydroplanes; the air required is picked up from the surface by means of an appropriate telescopic arrangement and it has the particularity of not being hermetically sealed in the immersed condition. It is totally safe since it rises automatically to the surface when the motor stops.
Abstract: The invention concerns a releasing mechanism for a parachute which is stowed in a container held closed by a safety string against the pulling force of a preloaded spring. This safety string is fixed to a container and can be released by action of an energy storage, e.g. a detonator or a preloaded spring. The energy set free by controlled ignition or triggering can either destroy or release the safety string.
Abstract: The present invention is an inflatable life belt of light weight, compact construction which is normally worn around the waist or hips of the individual, the size of which does not interfere with the activities of the individual while on board the ship, thereby rendering it feasible to use at all times without discomfort or in any way hindering normal physical activities. The belt encircles the body and is detachably engaged therewith by suitable belt means, the belt comprising two buoyancy sections of similar size which are folded one on top the other for sake of compactness. Each section of the belt includes a closed chamber; at least one of the chambers is automatically inflatable by suitable means such as a compressed gas cartridge mounted on the belt. The other closed chamber may be similarly inflated independently of the first chamber, or, alternatively, may be filled with an inherently buoyant material, such as foam, to render the life belt operative as soon as the individual enters the water.
Abstract: A crane leg connection is disclosed in which a crane has a frame length greater than its width, and has supporting legs including facing leg members connected to the frame and extending from the frame downward and away from each other and away from the frame in a direction transverse to the length of the frame. A support beam is mounted on the frame, and at least one of the leg members is connected to the support beam. A support arm connects the support beam and the frame together and carries the vertical load on the frame and transfers that load through the support beam to the leg. The support arm is connected to the support beam and frame such that the leg and frame are movable relative the each other transversely to the length of the frame. Another arm is affixed to at least one of the leg members and extends toward the frame, and an arm affixed to the frame extends toward the arm affixed to the leg member.

Abstract: A fire suppression system for a decorative tree, such as a Christmas tree, of the present invention wherein, disguised, for example, as a Christmas gift or incorporated as an integral part of the stand for the tree itself, there is provided a canister with a dry, substantially inert chemical, such as Halon, or similar fire suppressant substance, is disclosed. The fire suppressant substance is forced, e.g., by the application of pressure, when a heater smoke-sensitive sensor, released by a solenoid valve, is used to project the dispersant through a tubular plenum to a dispersant nozzle contained within, or as an integral part of, an ornament, e.g., a star, atop of the decorative tree. The flow of the fire suppressant fluid is preferably directed outward from a plurality of oval-shaped holes, preferably at least four such oval-shaped holes, which encircle a cylinder-type nozzle so as to provide dispersant to all directions surrounding the tree.
Abstract: A fire suppressor having a motor and a pump affixed to a tank for the fire suppressant mountable on the back of a user and which can be changed from a spray configuration to a fill configuration for fire site vicinity filling. A fuel tank for the motor mounted on the fire suppressant tank is enclosed to prevent sparks from reaching the fuel.
Abstract: An apparatus for automatically raising and lowering boat motors includes a mounting configuration that allows the motor to move up out of the water and down into the water. A hydrofoil is connected with the motor. When the boat is propelled by a second motor, the water pushes up on the hydrofoil, forcing the first motor up out of the water. A locking device can be used to maintain the first motor in the up position. The locking device can be disengaged to allow the motor and hydrofoil to fall into the water. Alternatively, the motor and hydrofoil can be maintained in the up positon by the force of water against the hydrofoil. When the second motor is shut down the motor and hydrofoil automatically drop into the water.
