Abstract: A special fuel is formulated for use with diesel engines which are used infrequently in emergency situations.

Abstract: A method of using a petroleum based fuel in an internal combustion gasoline engine. The fuel has a flash point of at least 100.degree. F. and the fuel is heated, within the engine, to a temperature above 100.degree. F. The heated fuel is introduced into the cylinders in the engine and ignited within the cylinder to start the engine. The heat source is removed after the engine has become warm. In an alternate embodiment, the electrodes of the spark plugs are continually energized until the electrodes are at a temperature above the flashpoint of the fuel. The electrodes of the spark plugs are then energized intermittently and the fuel is introduced into the heated cylinders to ignite the fuel in the cylinders in a selected sequence.

Abstract: The combination of a container having an emergency fuel therein for an internal combustion engine. The container is disposed in a trunk of a vehicle or in a storage compartment on a boat. A handle is formed on a body of the container. A closable outlet is formed on the body. A spout is adapted to be connected to the closable outlet. The container is manually releasably retained in the trunk of the vehicle. Also a method is disclosed of safely storing a stable emergency fuel in the trunk of a vehicle or in a storage compartment on a boat.

Abstract: An emergency fuel for internal combustion engines is stable for storage for a year or more. The emergency fuel is stored in a container which has an outlet sealed with a removable seal. The container is prevented from being reused for storage after the seal is removed. The fuel is a mixture of two fractions of refined mineral spirits, one fraction being 58-50% by weight and having 0% aromatics, the other fraction being 42-50% by weight and having 100% aromatics. A biocide is added to the mineral spirits.

Abstract: An emergency alternative fuel for internal combustion engines is stable for storage for a year or more. The alternative fuel is stored in a container which has an outlet sealed with a removable seal. The container is prevented from being reused for storage after the seal is removed. The fuel is a refined mineral spirits and may have 0-30% by volume mixed isomers of primary amyl alcohol blended therewith. A biocide is added to the mineral spirits.

Abstract: The tissue expander includes a closed shell structure having a shell wall formed of a needle-penetrable material with self-sealing characteristics. The shell defines a fluid expandable chamber. In some embodiments of the invention, a self-sealing layer of elastomeric material is joined or otherwise bonded to an inner surface of a non-flowable layer of elastomeric material. In other embodiments of the invention, the self-sealing layer is joined to the outer surface of a layer of non-flowable elastomeric material. The self-sealing layer may also be sandwiched between two layers of non-flowable elastomeric material. In a further embodiment the self-sealing layer constitutes the entire shell of the tissue expander. In all embodiments of the invention, a needle stop member is provided to prevent a needle that accesses the fluid chamber from passing outwardly of the tissue expander in the same direction in which it has accessed the fluid chamber.

Abstract: Metallic surfaces are coated with vitreous enamel by a process in which a cleaning pretreatment of the metal surface to remove surface oil is not required. An enamel-forming material is applied to metal surface coated with a polybutene as the surface oil. The thus-coated metal surface is fired at a temperature sufficiently high to cause the enamel-forming material to form a vitreous enamel coating. The preferred method for applying the enamel-forming material is electrostatic deposition.

Abstract: A small continuous loop tape recorder is connected to receive audio signals from a broadcast receiver, and a timer is provided to activate the recorder at intervals to record selected broadcast events. A mechanism is provided to manually activate the playback portion of the recorder whereby a previously recorded event is played back at a desired time. The receiver may be an integral part of a self-contained broadcast recorder unit, the receiver may be a conventional AM or FM broadcast receiver to which the recorder unit is connected, or there may be a combination of a self-contained receiver-recorder unit with a conventional broadcast receiver.

Abstract: A device for the calibration of the safe load indicating apparatus on cranes and derricks that have a pivoted, extensible boom luffed by a hydraulic ram. The device operates by combining electrical signals corresponding to the actual turning moment of the unloaded boom at given boom positions with generated calibration signals corresponding to the turning moment for the theoretical maximum load at the boom positions, by comparing these combined signals to the safe load signals from the crane's law generator unit and by adjusting the law generator unit accordingly.This invention relates to a method and apparatus for the calibration of safe load indicating apparatus for use with cranes, derricks and other lifting apparatus of the type having a pivoted, extensible boom which can be luffed by an hydraulic ram or other boom supporting means.

Abstract: A crane safe load indicator combines signals representing the total loaded boom turning moment and the turning moment of the boom alone to derive a third signal representing the turning moment of the load alone. The third signal is compared with a signal representing the crane's maximum safe load moment to indicate available lifting capacity.
