Abstract: An Aircraft Escape (AEC) is designed for manned atmospheric or space vehicles having a fly away capability at any time during the flight of the parent aircraft. The AEC houses the crew, passengers, life support systems, aircraft flight controls, propulsion, navigation instruments, communications equipment, and deceleration devices to permit safe landing of the escape cabin on land or water. A rocket or mechanical device provides the means to actively separate the escape cabin from the parent aircraft during an emergency.
Abstract: There is described a demand valve for a breathing apparatus wherein a pilot jet of the demand valve is controlled by a pivoting lever resiliently held against a planar face in which the pilot jet is formed. The pilot jet is preferably formed in a land surface surrounded by a recessed area of the planar face, and opening of the pilot jet is effected by movement of a control projection mounted on the pivoting lever. The area of the control projection is preferably greater than the area of the land surface.
Abstract: The invention relates to an arrangement in a vehicle intended and equipped for various display purposes. The arrangement comprises means for tilting the vehicle floor in at least part of the vehicle. This way the vehicle can be rapidly and flexibly formed into an auditorium with a tilted floor, and a conference or showroom with a level floor.
Abstract: An automatic handgun has a support member fixed to the end of the barrel and engageable with the slide when the slide moves forward. The mating surfaces of the support member and the slide have clutch surfaces machined into them so the two surfaces lock together snugly, thereby holding the barrel and slide together accurately. A guide rod may also be fixed to the support member to assist in holding the proper relationship when the slide is moved rearwardly.
Abstract: A body treatment apparatus has two separate but contiguous tubs to provide selective treatment to the feet and the upper body. A person will sit in one tub, and the person's feet will be in the other tub. The knees will be over a dam separating the two tubs. Each tub has separate fluid inputs and separate drains, so each may receive different fluids, and at different times. The entire tub unit can be rotated between a position in which the person is in a sitting position, and a position in which the person is reclining, with the feet higher than the head. Covers are provided for use when desired, such as during steam treatment.
Abstract: A face mask for a self contained breathing apparatus has two pairs of straps fixed to the frame of the mask, the straps being fixed to a net or woven head piece. The straps at the top of the head piece are fixed with respect to the mask, and the bottom straps are adjustable to tighten the mask against the face of the user. The nose cup has ribs that receive legs of a mounting member for eyeglasses. The eyeglasses include frames, with support arms that are slidably fixable to the mounting member. The mounting member moves towards and away from the eyes of the user, and the support arms move up and down with respect to the nose cup, for full adjustability of the eyeglasses. The nose cup of the face mask is adjustable by either removing a portion at the chin and shortening the mask, or simply removing the portion to allow the user's chin to extend beyond the nose cup while still inside the face seal.
Abstract: A backframe for a self contained breathing apparatus (SCBA) is formed of a molded shell having some depth, and a closure plate fixed to the shell to provide an enclosed volume. The molded shell with the closure plate yields a good weight-to-strength ratio, and provides a water- and dust-resistant enclosure for control components of the SCBA. A water-tight battery compartment is enclosed within the shell so the batteries are separated from other components. A low air pressure alarm provides an auditory signal, and may also include a tactile signal. A buddy breathing hose can be pulled from the backframe to provide a reasonable length tether; and, by connecting two such buddy breathing hoses, twice the length is provided.

Abstract: An infrared heat emitting device comprising a container having a bottom, end and side walls extending upwardly from the bottom, a top rotatably interconnected with one of the walls and disposed remote from the bottom, insulation material disposed on the interior of the container, and a heat bag disposed intermediate the top and at least a portion of the insulation whereby infrared heat is emitted through the top.
Abstract: A breathing apparatus comprises a supply of breathable gas and a facepiece by which breathable gas is supplied to a wearer, the facepiece including a supply valve for delivering gas to the interior of the facepiece, and an exhaust opening closeable by an exhaust valve for allowing the egress of exhaled gas from the facepiece. The exhaust valve comprises a movable valve member which, in a first position, closes the exhaust opening in the facepiece, in a second position is displaced toward the interior of the facepiece relative to the first position while still in sealing engagement with the exhaust opening to open the supply of breathable gas, and in a third position is displaced outwardly of the facepiece relative to the first position to open the exhaust opening to allow the egress of exhaled gas. The valve member is biased towards the second position by a single significant biasing means. A sealing element is preferably interposed between the valve member and the exhaust opening.
Abstract: A hand stretching method and apparatus mimics a well known exercise to reduce the problems with repetitive stress injury. A body of resiliently deformable material has flat and parallel top and bottom surfaces, with a cutout at one edge of the body. A user's hand is placed on the body, with the palm of the hand spanning the cutout. By pushing down on the hand, the opposite sides of the palm are urged apart, opening the carpal tunnel and relieving compression on the blood vessels and nerves. A user may place one hand on each surface of the body and urge the hands towards each other for treatment of both hands simultaneously. The body is preferably made of an expanded polymeric material such as polyurethane. Layers having different compression factors may be utilized; and, darker colored surface layers of material may be adhered to the top and bottom surfaces so the surfaces will not readily show dirt.
Abstract: A decoration for a lamp shade is in the form of a sculptured work that is visible when the lamp is turned off, and, when the lamp is turned on, the decoration shows in profile, the decoration having a pleasing appearance both as a sculptural work and as a profile. The decoration has a ferromagnetic member as a part of the decoration, and a permanent magnet is attracted to the plate. The magnet may be placed inside the lamp shade to fix the decoration to the shade outside of the shade, or the magnet may be on the outside, and attracted to a wire of the shade. The decoration may be used singly or in multiples. One version is stamped from brass sheet, with a plate soldered on, then the decoration provided with a finish such as antiquing or gold plating.
Abstract: A vehicle repair rack having a platform for receiving vehicles for straightening is tilted as it is raised from the floor for easier loading of low vehicles, without the vehicle's bottoming out. The repair rack uses a parallel linkage to raise the platform. The platform is one link of the parallel linkage; and, the link that is parallel to the platform is allowed to elongate as the platform is raised, thereby causing the platform to move into non-parallelism with respect to the elongated link, so the platform is tilted. The parallel linkage includes legs as the other two links, and a connecting rod between the two legs is the elongating link. One end of the connecting rod has a slot that allows the connecting rod to move axially to a limited extent for the elongation.
Abstract: A place keeper, for use with a straight edge for designating a row on a cross-stitch pattern, is slidable along the straight edge so the straight edge designates a row, and the place keeper designates a column. Two or more place keepers can be used to designate a group of columns, with one place keeper on each side of the columns to be designated. The straight edge is preferably a line magnifier having magnets at each end to hold the magnifier to a magnet board. The magnets may space the magnifier from the magnet board to allow the place keepers to slide without interference from the surface on which the magnifier is resting.
Abstract: A spring clip has jaws connected by a throat that provides spring action to urge the jaws together, and levers on each jaw that can be extended to provide a mechanical advantage for opening the jaws, or can be retracted so the levers are juxtaposed on the jaws. The jaws have bosses thereon, and openings are defined in the bosses for receiving the levers. The openings have tongues along their sides, and the levers define grooves along their sides so the levers can slide smoothly into and out of the opening. Detents provide stops at retracted and extended positions of the levers, and a screw riding in a slot provides a positive stop to prevent inadvertent removal of the lever.
Abstract: Polystyrene pellets are continuously supplied to extrusion means which continuously forms an elongated element whose form and shape is stabilized by hydraulic cooling means through which the element is moved, following which the element is dried and heated and then supplied between heated pressure rolls along with a tape on one surface of which a coating has been applied and which includes a decorative film, the coating being in face contacting relation with a surface of the elongated element, the temperature of the pressure rolls and the velocity of the movement of the tape and elongated element therebetween being correlated in such manner as to cause a decorative film to be removed from the tape and deposited on the elongated element, following which the element and tape are engaged and transported away from the pressure rolls into a cutting station at which the element is severed into desired lengths.
