Abstract: A hydrofoil apparatus for attachment to a marine vessel having a first pivot means for positioning the rotational axis of a gooseneck shaft parallel to the yaw axis of the hull and a trailing load support arm having a forward end coupled to the gooseneck. A planing surface sensor or planing foil rides on the water surface. The planing surface provides a hydrodynamic force to hold the planing surface sensor on surface as the vessel moves with forward velocity. An elongated body member is pivotally coupled to rotate on a first pitch axis with respect to said planing surface sensor. The elongated body member is pivotally coupled to the trailing load support at its aft end. A vertical fin is coupled to support the elongated body member. The fin maintains the planing surface sensor forward of said second pitch axis. A lifting foil raises the bow of said marine vessel by provide a lifting force via the fin.

Abstract: A telescoping extension chute has a first semicircular section with an inlet end for pivotal connection to a main chute on a mixer truck and a pair of tubular tracks attached along upper longitudinal edges. An intermediate section with a semicircular cross-section of larger radius telescopes over the first section and has a pair of tubular tracks attached along upper longitudinal edges which extend through slots formed in the bottom walls of the first section tracks. A third section with a semicircular cross-section of still larger radius telescopes over the intermediate section and has a pair of bars attached along upper longitudinal edges which extend through slots formed in the bottom walls of the intermediate section tracks. Rollers attached to the tracks cooperate to provide relative telescoping movement and a locking mechanism prevents relative movement in any extended position.

Abstract: A fire extinguisher of compact, self-contained character is installed in electrical equipment by being mounted within an aperture of a housing for the equipment. The extinguisher has an elongated vessel for containing under pressure a fire extinguishing substance such as halogenated hydrocarbon type. A nozzle is carried at one end of the vessel and is closed by fusible material which melts at a predetermined temperature to permit discharge into the housing. The nozzle is formed as part of a fitting which carries a washer-like disc having an adhesive substance on it to permit adhesive securement of the extinguisher to the equipment housing, with the greatest portion of the vessel extending exteriorly of the housing and only a small portion of the extinguisher thus extending interiorly of the housing. The vessel has a relatively high aspect ratio, such as permitting it to be installed in an aperture defined by an electrical knock-out.

Abstract: A parachute system for an airman ejected from an aircraft in an ejection seat includes at least one drouge parachute housed within a rigid hollow container. In conventional manner, the drogue parachute is connected by lines with releasable attachments on the seat, one of the lines being further connected with the main parachute so that the latter will be deployed after release of said attachments. The container is formed as a projectile mounted in a gun mounted on the ejection seat. The container has, at its end facing away from the direction in which it is fired, a closure connected with the lines and with the drogue parachute. When the container and closure are fired from the gun, and the closure is arrested abruptly by the lines, the container continues in its trajectory whilst the drogue parachute is drawn from the container and deployed by the lines.

Abstract: A parachute-type safety lowering or descent system (10) for helicopters or other types of hovering aircraft includes a rotor hub assembly (12) to which is secured to the top thereof a parachute housing (14), for containing the safety lowering parachute, through means of a dual set of vertically spaced ball bearings (52, 58) for rotationally isolating the parachute housing (14) from the induced rotation effects of the hub rotor assembly (12) under normal aircraft operating conditions. In an emergency, however, such as, for example, in the case of a rotor, rotor blade, rotor hub assembly, or rotor drive engine failure, malfunction, fracture, or separation, the safety lowering parachute will be deployed whereupon the entire weight load of the aircraft will be borne by the safety parachute.

Abstract: A sender propels filter rod sections at a constant or at a variable frequency into a pneumatic conveyor which delivers the sections into the magazine of a receiver serving to store a supply of sections next to a filter tipping machine. The operation of the sender is interrupted for a fixed or for a variable interval of time after the sender propels a preselected number of sections. The intervals of operation and idleness of the sender are regulated in dependency on fluctuations of the quantity of sections in the magazine of the receiver. The frequency at which the sender propels the sections can be varied by varying the speed of a fluted rotor which transfers sections from a source to the sender, and the ratio of the intervals of operation and idleness of the sender is determined by several timing pulse generators which receive signals denoting the quantity of sections in the magazine and control the operation of a blocking device which can prevent the transfer of sections from the source into the sender.

Abstract: A self-activating fire extinguisher which is particularly useful as a Christmas tree ornament is comprised of a thin-walled sealed glass container having a quantity of a fire extinguishing liquid such as Halon 2402 contained therein. When in the vicinity of a fire, the temperature of the liquid will rise causing it to boil which increases the pressure within the container. Eventually the container will break, releasing the liquid; the fumes from which extinguish the fire. In order to prevent glass fragments from being thrown about when the container breaks, the majority of the container is coated with a plastic material. This material adheres to the glass and maintains the broken pieces of glass together even at high temperatures. The liquid and fumes are released through a small portion of the container that is not coated by the plastic.
