Releasable joints of adhesive are provided between the metal rails and the edges of the composite panels where a web of the panel and the web of the rail extend across the panel at an angle to the first and second surfaces different from 90 degrees so that the web of the panel meets the flange of the panel at an angle greater than 90 degrees.

Abstract: A garbage bag holder includes a base frame and a pair of side frames extending upwardly at spaced apart positions from the base frame to receive a paper bag or a plastic bag between the side frames. Depending frames are suspended from the top ends of the two side frames so as to be arranged to extend downwardly only partway into a paper bag so that the particular size of the frame is not required to be critically matched to the bags being used nor does the frame become soiled by the contents of the bag. Outward biasing force can be applied to the depending frames by the side frames along the full height of the depending frames to prevent any tearing at the top edges of a paper bag. Alternatively, a plastic bag can be held under tension between the top ends of the side frames.

Abstract: A vehicle is wrapped by a printed adhesive film where the film is also applied over doors and other areas intended not to be covered. The film is cut at the door edge and over the area by adhesively attaching a tape having a release coating on the front surface and carrying a filament along a center of the front side. The printed film is applied over the door, the area not to be covered and the tapes and is cut along the door edge and around the area by pulling the filament from the tape so that a strip of the film at the door edge and the film over the area can be removed. The film can be stretched and pulled away from the tape for reapplying for proper fit.

Abstract: A downhole flow pulsing device comprises a housing connected in series with a drill string and a valve with a rotating portion in the housing arranged to vary an area of a flow passage through the housing. A fluid actuated positive displacement motor drives rotation of the valve. A drive link permits the rotating portion of the valve to be optionally coupled directly to the motor of the drill string. The valve includes radially oriented rotating ports intermittently communicating with surrounding fixed ports and a bypass channel. Axial displacement of the rotating ports relative to the fixed ports and bypass channel permits amplitude of the downstream fluid pulses to be adjusted. The valve includes a number of circumferentially spaced ports which differs from a prescribed number of pressure fluctuations in the fluid for each full rotation of the rotor of the drill motor.

Abstract: Bedding material for livestock is produced by extruding straw through a conventional cubing system rather than a conventional pellet mill. The cubing process generates friction in turn changing the properties of the straw making the straw particles highly absorbent. The cubing process allows for greater particle size in the finished product as compared to pellets produce in a conventional pellet mill. The process involves the following: shredding the straw to proper size, cubing the straw into cubes and flakes, cooling, storing and packaging. The cubing process requires 40% less energy based on throughput of finished product, thus making the material more affordable to larger farming operations. Some other properties include a higher bulk density than large conventional bales or wood shavings, less dust when applying, a pasteurized product, easier to handle and spread compared to straw bales, wood shavings and sawdust.

Abstract: A light strip comprises an elongate core layer of insulating material having a plurality of light mounting apertures extending through the core layer between the two opposed faces of the core layer and receiving respective light emitting diodes therein. Two conductive elements extending in the longitudinal direction along the outer surface of the elongate core layer between which the light emitting diodes are connected. A cover layer spans in the longitudinal direction adjacent each one of the two opposed faces of the elongate core layer to enclose opposing ends of the light mounting apertures with the light emitting diodes therein.

Abstract: A scooter has a platform on which a rider can stand, a front wheel attached to a steering system including an upstanding handle bar and rear wheel which is driven. The scooter can be folded at a hinge line across the platform so to allow it to collapse. A case for the scooter includes a front part and a rear part covering the front and rear wheels with the parts brought together by the collapsing of the platform. This folding action also uses a pivot link to move the front and rear wheels pivoted within the respective case parts to a folded position. The steering includes a headstock with the steering bar connected to the front fork by a drive coupling which converts the rotation of the steering bar about the generally vertical axis to the rotation of the fork about an inclined axis.

Abstract: A bougie device for guiding insertion of an endotracheal tube into an airway of a person, comprises an elongate body of shape memory and self-lubricating material, for example Teflon™. Accordingly no lubrication is required for insertion into the airway for ease of cleaning and sterilizing for reuse. Also, the amount of curvature of the overall rod as well as an angle of the tip of the rod can be adjusted due to the shape memory characteristics of the body to accommodate a particular patent's airway. The body can also be suitably sized to have vibration transmission characteristics such that a contact with one end of the bougie device with tracheal rings of the patient can be felt by a user.
