Abstract: The present disclosure relates to aerosol delivery devices, methods of producing such devices, and elements of such devices. In some embodiments, the present disclosure provides devices configured for vaporization of an aerosol precursor composition that is contained in a reservoir and transported to a heating element by a liquid transport element. The liquid transport element may include a porous monolith.

Abstract: A device for retaining a bicycle chain on a sprocket includes a base plate defining a plurality of fastener openings centered on an origin. A center of each of the plurality of fastener openings is disposed at a first radial distance from the origin. The origin defines an axis extending substantially orthogonally from a plane defined by two lines extending from the origin and at least two centers of the centers of the plurality of fastener openings. A first guard is secured to the base plate and includes a first guard retaining surface including a first curved surface defined by a second radial distance from the axis that is greater than the first radial distance and a first guard guiding surface having a first end adjacent the first guard retaining surface and a second end distal from the first end. The first end is disposed at the second radial distance from the axis. The second end is disposed at a third radial distance from the axis. The third radial distance is greater than the second radial distance.

Abstract: A pivotal sliding bi-fold door structure mounted in a door frame having a track slidably accommodating the bi-fold door structure. The bi-fold door structure comprising at least two door panels pivotally connected by a hinge member. The improvement comprising a bi-fold door safety wedge including a main body structure. A pair of non-parallel edges on opposite sides of the main body structure facing away from each other and extending along the main body structure and nearly intersect to form a vertex at a front portion of the main body structure. Another edge extending between the non-parallel edges at a back portion of the main body structure. An elastic strap for removably elastically securing the main body structure to the hinge member, where the removable elastic securing strap has the characteristic of adjustably positioning the vertex of the main body structure in adjacency with the hinge member when the bi-fold door structure is in an open position.

Abstract: A portable building system of variable size (20) consisting of a series of individually collapsing web beam frames (22) which serve simultaneously as a support structure for the exterior covering material (30) and as a support structure for a highly adaptable interior furnishing system. Individual web beam frames (22) are comprised of multiple segments including vertically oriented outer segments (32) which have a width measured horizontally in the plane of their span sufficient to support furnishing components 26 substantially within an area directly between a pair of consecutive outer frame segments 32 in a strong and convenient manner. Additional overhead segments (34) are joined to each other and to outer segments (32) with corresponding mortise (36) and tenon (38) like surfaces for a fast and positive assembly. Purlins (24) attach to the frames, joining them in sequence.

Abstract: A double-bladed combat weapon includes a handle having slotted ends. A knife blade having a semicircular tang, which has a plurality of index notches, is pivotally disposed in each slotted end of the handle. An indexing mechanism is disposed in each end of the handle and engages one the index notches of the blade tang. A release for each blade is provided to permit the user to swing the blades selectively from a rearwardly directed position to a forwardly directed position, as well as intermediate positions during combat.

Abstract: A portable shelter structure (10) of variable size consisting of an even number of individual, folding, modular units (12) which, in their folded condition, serve as shipping containers for the shelter. Rigid floor and rigid sidewall sections (22, 28) are hinged (24) along an adjacent edge allowing rotation of the sidewall section from a closed position to an upright position so that the sidewall is substantially perpendicular. Collapsible roof support beams (72) and flexible, collapsible roof covering units (14) are stored in a cavity created between the floor (22) and sidewall (28) sections when they are in their closed state. Collapsible end walls (16) having a door structure (17) therein can be stored in the modular unit cavity or in a separate vestibule packing unit (18) which attaches to the end wall as a separate closed space outside the end wall door.

Abstract: A system for improving the fuel economy of internal combustion engines comprises a thermostatically controlled heater located in the fuel line between the fuel tank and the carburetor for heating the fuel to a temperature just below its vaporization temperature. This temperature is controlled to result in a more complete vaporization of the fuel upon entering the carburetor. Another part of the system supplies a fuel additive in the form of a xylene/oil mixture into the carburetor by way of the vacuum advance line to add approximately one ounce of the additive mixture to every fifteen to twenty gallons of fuel. Significant fuel economy has been realized along with a cooler exhaust temperature of the combustion products and a reduction in the amount of pollutants in the engine exhaust.

Abstract: An improved strap guide for a package strapping system having an upper movable horizontal strap guide section, integral with or connected to a compression bar having press feet extending on each side of the movable strap guide section toward a package to be strapped and means for moving the upper strap guide and compression bar toward and away from the package to be strapped.

Abstract: A package strapping machine for strapping a package to a pallet, which pallet is usually constructed from lumber and is of standard shape or configuration. The pallet comprises generally a supporting platform for the package with longitudinally parallel extending stringers secured to the underside of the supporting platform. The strapping machine is provided with a strapping station where the package is tied to the pallet and is so constructed that a strap is carried beneath the stringers and through a strap ring including an arch around the package if the pallet is facing in one direction, because a pallet position sensing means, such as a ray of light which is provided at one side of the pallet, cannot pass through the solid stringers to a photo-sensitive device located at the other side of the pallet. However, if the pallet is turned 90.degree. so that the voids between the stringers which extend completely through the pallet structure are positioned 90.degree.
