A body weight trainer fitness device allows for the strengthening and normalization of functional movement patterns for those who are not otherwise able. The device accomplishes this with the use of resilient strength bands which are provided in the form of heavy duty rubber bands of varying widths. The bands are selectively attached to a frame via selectively-moveable band holders. The device may then be used to offload the user's weight and thus decrease resistance or it can be used to increase the resistance of an exercise. The bands can be oriented to offload the user's body weight allowing a user to exercise with proper form. Once normal functional movement can take place without the bands, the device may be configured to utilize the bands as resistance to improve these functional motion patterns.

The present invention relates to a self-molding permanent agent and a method for proceeding free-rod and free-band type permanent, more particularly to a self-molding permanent agent comprising (a) a reducing composition containing a reducing agent reducing a disulfide bond of cystine on the hair and a molding stimulant spontaneously molding to fix a hair design; (b) a molding composition inducing to mold after reacting with the molding stimulant; and (c) a softening composition releasing the action of a molding stimulant, and a method for pressing a free-rod and free-band type permanent, which overcomes a disadvantage in the conventional method for pressing a permanent that needs to wear a curling device such as rods for a permanent (perm rod) or rubber band and improves to apply a wave set without a hair-curling device for a short time, since it has a self-molding feature.

Standard test methods for determining one-dimensional consolidation properties of soils using incremental loading in accordance with ASTM D2435, or AASHTO 216, and of those of other international and organizations, do not accurately predict the values of vertical settlement, coefficients of consolidation in horizontal and vertical directions, and modulus of elasticity in vertical direction, because fixed ring used in these tests do not allow horizontal settlement and dissipation of excess pore-water pressures in horizontal direction, whereas, in field, under application of a vertical load, both horizontal and vertical settlements occur along with dissipation of excess pore-water pressures in both vertical and horizontal directions. To overcome this more than 100 year old problem, the inventor (Dr. Ramesh Chandra Gupta, Ph. D., P.E.) has invented a test device for determining three-dimensional consolidation properties of soils, using a flexible ring which permits development of horizontal and vertical displacements, and dissipation of excess pore-water pressures in both horizontal and vertical directions, along with increased lateral resistance as takes place in field at any depth in a soil deposit when vertical load at the surface is applied.The flexible ring consists of filter fabric around the soil specimen, rubber membrane around the filter fabric, circular segmental metal plates around the membrane and elastomeric rubber bands or spring loaded jacket around the segmental plates, and allows horizontal and vertical displacements, dissipation of pore-water pressures in horizontal and vertical directions to take place with increased lateral resistance with each increment of vertical load like those in the field. Thus new test device simulates field condition to allow accurate determination of three-dimensional consolidation properties of soils (such as settlements, coefficients of consolidation in horizontal and vertical directions, and modulus of elasticity).For this new test device, conventional incremental consolidation frame or triaxial type chamber system either with the triaxial loading system or modified to adapt to incremental consolidation frame, shall be used to perform three-dimensional consolidation tests.

A display that can be expanded from a collapsed position for storage and transport to an expanded position for free-standing operation and use. A spinal member is disposed between front and back panels such that in the collapsed position, the spinal member maintains the two panels substantially adjacent one another in a generally two-dimensional shape. Upon movement of at least a portion of the spinal member relative to the panels, parts of the spinal member bias the panels apart from one another to form an expanded, three-dimensional shape. This shape provides a sufficient footprint of the display relative to its height that the display can be free-standing. The cooperative relationship between the spinal member and the panels is such that no rubber bands or related elastic devices are required to maintain the display in the expanded position.

The invention relates to a rod climbing robot, which includes stepping motors, a circuit board, rollers, rubber bands, a circuit board fixing frame, a supporter, a sleeve, a screw thread connecting rod, a nut, a stationary roller, an elastic switch and a gray scale sensor. The two sides of the supporter are respectively provided with one stepping motor and one roller connected with the stepping motor. Each roller is connected on the supporter through the sleeve. Each roller is entwined by four rubber bands. A switch of the stepping motor is connected with the elastic switch. The elastic switch controls the motors and a small horn to work and also plays the role of controlling the moving direction. The gray scale sensor is arranged below the rod climbing robot. When the robot descends near the ground, the gray scale sensor generates a high-low level change as the beam goes dark; the rod climbing robot generates a speed reduction motion and stops gradually to realize the soft loading of the robot. The invention replaces pneumatic motion or hydraulic motion to supply power improves the working quality and efficiency and greatly improves the safety factors for working high above the ground.

The expandable jacket consists of the rubber membrane surrounding the cylindrical specimen, circular segmental metal plates surrounding the rubber membrane, and elastomeric rubber bands or rings around the segmental plates to permit uniform radial expansion and maintain uniform diameter of the specimen during the test and thereby providing accurate values of deviator stress, volume change characteristics and shear strength of soil specimen. To determine the three-dimensional coefficient of consolidation and coefficient of consolidation in horizontal direction, the flexible ring consists of all above structural components of expandable jacket except that a filter fabric or paper is wrapped around the cylindrical specimen, and then rubber membrane is mounted surrounding the filter paper or paper. The calibration device for calibration of the expandable jacket and flexible ring shall provide the magnitude of correction to be made in deviator stress and lateral resistance provided by the rubber bands or rings during the test.

Standard test methods using a fixed ring for determining one-dimensional consolidation properties of soils represent a subsurface condition where settlement and dissipation of excess pore pressure is possible only in vertical direction. This subsurface condition never occurs, as settlements and dissipation of excess pore pressures always occur in horizontal and vertical directions. Dr. Ramesh Gupta has invented a test device for determining three-dimensional consolidation properties of soils, using a flexible ring permitting displacements and dissipation of excess pore pressures in both horizontal and vertical directions, and affording determination of coefficients of consolidation in horizontal and vertical directions including three-dimensional coefficient of consolidation, and modulus of elasticity. The test device consists of a flexible ring consisting of filter fabric around the soil specimen, rubber membrane around the filter, circular segmented metal plates around the membrane and rubber bands or rings around the plates. Both incremental or triaxial type loading can be used with this device.

A flexible cover is formed from a rectangular sheet of plastic film material and a continuous elastic or rubber band. The sheet has a predetermined amount of material cut from each corner. The sheet is placed onto a table between four posts that extend from the table. The sheet is positioned so that a post lines up with each corner of the sheet. A rubber band is stretched across the four posts into a similar shaped rectangle and rests just above the sheet. The stretched rubber band now has four sides which correspond to the four sides of the sheet. The side edges of the sheet are folded inward and over the stretched band and heat sealed directly to the sheet. The band is now sealed within a pocket that is formed along the sides of the sheet. Each corner of the stretched band is released from its post, allowing the band to relax and pull the four corners of the sheet toward the center. This creates a generally circular cover with a near rectangular mouth which can be used on both rectangular and circular shaped containers or plates with similar sized openings.
