mp Portable device to compress bows By www.freepatentsonline.com Published On :: Tue, 31 Mar 2015 08:00:00 EDT A portable device to compress a bow comprising a pulley system with a block and tackle and fixed pulleys which, by wiring, are connected to a set of fastening supports with fastening ends. The fastening ends fasten and pull the ends of the arms or limbs of a bow, under traction exerted by the block and tackle. The block and tackle has a drive portion and a brake controlling the traction and release of the cables connected to the fastening supports. Upon pulling the drive portion, the block and tackle produces the approach between the first and the second pulleys. This displacement between the pulleys acts on the cables which, through the fixed pulleys, cause the approach between the fastening supports. This displacement of the fastening supports overcomes the resistance of the bow and compresses it. Once the desired compressive level is reached, the brake or blockage is actuated. Full Article

mp Air baffles in railroad tunnels for decreased airflow therein and improved ventilation and cooling of locomotives By www.freepatentsonline.com Published On :: Tue, 14 Apr 2015 08:00:00 EDT Disclosed is a system and method for decreasing airflow and improving ventilation within a tunnel, such as a railroad tunnel, including a path for movement of a vehicle (e.g., train) therethrough. The system has a plurality of air baffles mounted within the tunnel, each device comprising a body and a mounting device. Each mounting device positions each body inside and along the length of the tunnel between the entrance and the exit. The air baffles are configured to restrict airflow at least in part in a longitudinal direction of the tunnel, thereby increasing a relative difference between a vehicle speed and air speed in a tunnel annulus when the vehicle passes through the tunnel. The restriction (e.g., decrease) of airflow in the tunnel reduces the piston effect resulting from the vehicle or train passing through, thus reducing emissions and heat generated by the locomotives in the tunnel.

mp Annular diaphragm compression driver By www.freepatentsonline.com Published On :: Tue, 14 Apr 2015 08:00:00 EDT An annular diaphragm compression driver for electro-acoustic conversion has an annular diaphragm, which bears a moving coil, and a compression driver housing with a closed housing base. Opposite the housing base is a sound wave routing element having a sound discharge channel. The compression driver also has an annular magnet system unit, which has an annular magnet gap (M) and a compression chamber, adjoining the magnet gap (M), for the annular diaphragm. The open exit end of the sound discharge channel is in slot form and its entry start is annular. The sound path between the compression chamber and the entry start contains an annular collecting space. The collecting space and the sound discharge channel contain a central sound guidance body having a portion which merges to match the slot-like exit end. The sound discharge channel is formed between the sound guidance body and the sound wave routing element. Full Article

mp Optimized pattern of a damping layer for wall, floor, and ceiling constructions By www.freepatentsonline.com Published On :: Tue, 19 May 2015 08:00:00 EDT An acoustic damping article includes a substrate, wherein the substrate has a surface area S. The acoustic composition further includes a polymer resin. The polymer resin coats partially the surface area with a set of areas. The ratio of the coated areas over the surface area S is less than 1 and the polymer resin coverage is not greater than about 500 g/m2. Full Article
mp Dog vest with integrated flexible bumper By www.freepatentsonline.com Published On :: Tue, 14 Apr 2015 08:00:00 EDT A vest can be worn by a visually impaired pet, such as a dog, to help the pet navigate without hurting themselves by bumping into walls or objects. The vest includes plastic tubing with wire woven therein. The tubing is shaped like a halo that surrounds the front and sides of the pet's head. Should the visually impaired pet run into an object or wall, the halo will hit before their head hits and the pet will turn away before injuring themselves. The vest can be worn about their torso with their front legs fitting in leg holes of the vest. The vest can be adjustable to fit a range of pet sizes. The halo can also be adjustable to provide safe navigation of the pet. Typically, the vest is designed for dogs, but other visually impaired pets or animals may benefit by using the vest.
