| 20110146368 | Method for Making a Tube of a Telescopic Device - Disclosed is a method for making a tube for a telescopic device. The method includes the step of cutting a section from tubular raw material to provide a semi-product of the tube with a desired value of length, the step of pressing the wall of the semi-product of the tube for a first time to make cavities on an external side of the wall of the semi-product of the tube, and the step of pressing the wall of the semi-product of the tube for a second time to deepen the cavities so that the tube is made with a desired depth. | 06-23-2011 |
| 20110163216 | Highly Extensible and Easily Operable Telescopic Device - A telescopic device includes a first tube, a second tube in which the first tube is telescopically inserted, a third tube in which the second tube is telescopically inserted, a guiding unit for preventing rotation of the second tube in the third tube, a maneuvering unit for retaining the first tube in a desired position relative to the second tube, and a lock for locking the second tube in a desired position relative to the third tube. | 07-07-2011 |
| 20110271500 | Apparatus for Tensioning a Strap - A strap-tensioning apparatus includes a frame, a handle connected to the frame, a reel supported on the frame, two ratchets secured to the reel, a first detent supported on the handle and biased to engage with the ratchets, and a second detent supported on the frame and biased to engage with the ratchets. The frame includes two walls each including a recess. The handle includes two walls each including a lobe. The first detent includes a chamfered tip. The ratchets can slide on the chamfered tip of the first detent to allow a strap to be reeled out when the chamfered tip of the first detent is in the recesses of the frame. The second detent is disengaged from the ratchets by the lobes of the handle when the chamfered tip of the first detent is in the recesses of the walls of the frame. | 11-10-2011 |

| 20110179609 | STRAP-TIGHTENING DEVICE - A strap-tightening device includes a frame, a handle connected to the frame and a reel located on the frame. A first detent is located on the frame. A second detent is located on the handle. The second detent includes two horns each including a downward prong and an upward prong. The reel includes a cylinder and two ratcheted wheels attached to the cylinder. The ratcheted wheels are engaged with the upward prongs of the horns of the second detent during pivoting of the handle in a direction to cause the cylinder to reel in a strap. The ratcheted wheels are engaged with the first detent during pivoting of the handle in an opposite direction to prevent the handle from spinning the cylinder to reel out the strap. A withdrawing unit spins the reel to withdraw the strap. | 07-28-2011 |

| 20120082406 | HYBRID LUBRICATING MODULE - A hybrid lubricating module includes a housing and an assembly which consists of at least two elements and has an axial hole run through by a shaft. At least one of the elements has one set of multiple notches on one end surface communicating with the axle hole. The housing has a through axial cavity to encase the assembly. The outer wall surface of the assembly and the inner wall surface of the housing are assembled to each other to form at least one storage chamber to store lubricating media. The multiple notches on at least one adjacent element form at least one set of fine flow passages communicating with the axial hole and the storage chamber. | 04-05-2012 |

| 20100005602 | METHOD FOR MANUFACTURING ENVIRONMENTAL PROTECTION INSOLE - A method for manufacturing insole uses used footwear and recycled wooden articles are primary ingredients, which are pulverized to form particles of the recycled materials. The recycled wood, taking a ratio of weight of 15-35%, is uniformly mixed with matrix rubber that functions to adjust physical properties and foaming agent, and then pressed to form an insole material in a sheet form, which is deposited in a mold to be heated and pressurized for curing and setting thereby forming an insole featuring proper resilience and anti-bacteria and deodorization. The use of the insole is thus completely sanitary and comfortable and also features pollution- and nuisance-free use by repeated use in the sense of environment conservation. | 01-14-2010 |
| 20100325921 | ENVIRONMENTAL-PROTECTION SHOE SOLE MADE OF COMPLETE RECYCLED SHOES - An environmental-protection shoe sole made of complete recycled shoes is provided, which uses recycled used shoes as a primary constituent of the raw material thereof, which used shoes, after being processed to remove metal accessories mounted inside and outside the shoes, are subjected to shredding pulverization by a shredding pulverization machine and are then subjected to application steam for high temperature heating for deodorization and drying to form tiny pieces of recycled raw material, which can be used as a raw material for making shoe soles. This raw material is further mixed with a base rubber and a suitable amount of curing additives, activation prompting agents, and filling agents to form a moldable shoe sole raw material, which is put into a mold and heated and pressurized for curing and shaping, so as to realize total recycling of complete used shoes for pollution-free manufacturing of shoe soles. | 12-30-2010 |
