Polypropylene monofilament and tape fibers exhibiting certain creep-strain characteristics and corresponding crystalline configurations

Unique thermoplastic (polypropylene, specifically) monofilament and / or tape fibers and yarns that exhibit heretofore unattained physical properties are provided. Such fibers are basically manufactured through the extrusion of thermoplastic resins that include a certain class of nucleating agent therein, and are able to be drawn at high ratios with such nucleating agents present, that the tenacity and modulus strength are much higher than other previously produced thermoplastic fibers (particularly those produced under commercial conditions), particularly those that also simultaneously exhibit extremely low shrinkage rates. Thus, such fibers require the presence of certain compounds that quickly and effectively provide rigidity to the target thermoplastic (for example, polypropylene), particularly after heat-setting. Generally, these compounds include any structure that nucleates polymer crystals within the target thermoplastic after exposure to sufficient heat to melt the initial pelletized polymer and allowing such an oriented polymer to cool. The compounds must nucleate polymer crystals at a higher temperature than the target thermoplastic without the nucleating agent during cooling. In such a manner, the “rigidifying” nucleator compounds provide nucleation sites for thermoplastic crystal growth. The preferred “rigidifying” compounds include dibenzylidene sorbitol based compounds, as well as less preferred compounds, such as [2.2.1]heptane-bicyclodicarboxylic acid, otherwise known as HPN-68, sodium benzoate, talc, certain sodium and lithium phosphate salts [such as sodium 2,2′-methylene-bis-(4,6-di-tert-butylphenyl)phosphate, otherwise known as NA-11]. Specific methods of manufacture of such inventive thermoplastic fibers, as well as fabric articles made therefrom, are also encompassed within this invention.

Combined reconfigurable multi-purpose external orthopedic fixation device and multi-functional rehabilitative prosthesis

A combined, reconfigurable, multi-purpose external orthopedic fixation device and multi-functional prosthesis, for use alternatively as an external orthopedic fixation device for providing support and/or traction for a sprained, fractured, or broken limb of a warm-blooded animal, especially a human being, and as an artificial prosthesis for providing both substitute elementary limb functionality and substitute multi-purpose specific task functionality of a limb, especially an upper limb, such as a finger, hand, wrist, forearm, or elbow, of a warm-blooded animal, especially a human being, is disclosed. The apparatus includes at least one flexible tubular elongate member having a flexible strengthening rod therein, and a pair of end caps. Other embodiments of the apparatus further include one or a plurality of one or more additional elements including a cushioning support that is slidable along the elongate member; a stop for fixing the position of a cushioning support; a uni-dimensional joint for connecting ends of one or more elongate members together in a two-dimensional configuration; a two-dimensional joint for connecting ends of two or more elongate members together in a three-dimensional configuration; a panel of webbing material for supporting a limb; a rigid support member generally contoured to and for supporting a specific limb; and a variety of implements for performing certain useful functions, such as personal hygiene and grooming, eating, writing, and simple chores, that can be attached to one or more ends of an elongate member in place of the end caps.

Electric control baby pillow and control method thereof

The invention relates to an electric control baby pillow and a control method thereof. The pillow can be subjected to shape adjustment according to design modes and the sleeping state of a baby, so as to ensure that the stress of the head of the baby is changed during sleeping, and to prevent malformation of head caused by partial force for a long time. The electric control baby pillow comprises a pillow body and an electric controller, and is characterized in that the baby pillow is provided with a bottom plate; an air bag is arranged on each of the two sides of the bottom plate and is fixed on the bottom plate; the air bag on each side is fixed through a fastening strap; the pillow body is arranged on the fastening strap; a position sensor group is arranged on each of the two sides of the lower part of the pillow body; each air bag is connected with an air valve group; the air valve group is connected with an air pump; the air pumps and position sensors are respectively connected with a microprocessor control system; the two ends of the fastening strap are fixed on the outer side of the air bag; the middle end of the fastening strap is fixed in the middle of the bottom plate. The invention further provides a control method of the electric control baby pillow. The pillow can effectively avoid malformation possibly caused by the deflection of head, and enables babies to healthily grow.

Memory alloy auto-distraction locking interbody fusion cage and application method thereof

InactiveCN104771251AIncrease heightIncrease front and rear diameterInternal osteosythesisSpinal implantsDistractionSpinal cage
The invention provides a memory alloy auto-distraction locking interbody fusion cage which consists of a main body, auto-distraction holes, locking teeth, holding holes and a bone grafting hole, wherein the auto-distraction holes are symmetrically formed in two sides of the main body; the locking teeth are symmetrically formed in the upper sides and the lower sides of the auto-distraction holes, and the tooth tips of the locking teeth face outwards; the holding holes are located at the rear part of the main body; the bone grafting hole of which the shape is consistent with that of the main body is formed in the center of the main body and takes the inner edge of the main body as the boundary; and the auto-distraction locking interbody fusion cage is made from medical memory alloy. When the memory alloy auto-distraction locking interbody fusion cage is used, the locking teeth are pressurized at low temperature, and after the bone grafting hole is filled with a bone grafting material, a holder is adopted to clamp the holding holes to enable the memory alloy auto-distraction locking interbody fusion cage to enter through an operative route to be placed in an objective intervertebral space; after rewarming, the auto-distraction holes restore to the shape before pressurizing, and the tooth tips of the locking teeth are inserted into upper and lower vertebral endplates of the intervertebral space to complete distraction, pressurization and locking stabilization, so that the purpose of distracting and fixing vertebral bodies of the adjacent segments of the intervertebral space is achieved, and the operation is simple.

One-dimensional high-low-pressure turbine transition flow channel optimization design method

The invention discloses a one-dimensional high-low-pressure turbine transition flow channel optimization design method. The method aims to solve the technical problem that an existing method is poor in practicability. According to the technical scheme, an end wall profile equation meeting the transition flow channel geometric constraint is built by the adoption of a Bezier curve; the disturbance quantity meeting the orthogonal polynomials is generated afterwards, and correction is conducted on the generated extremely large disturbance quantity to prevent deformation of a disturbed flow channel; a new high-low-pressure turbine transition flow channel profile equation is generated based on the existing transition flow channel geometric profile equation; a flow field performance parameter is solved through a flow control equation on the high-low-pressure turbine transition flow channel center line; a total pressure recovery coefficient serves as an optimization objective function, and a complex method is adopted till an iteration result meets the accuracy requirement. According to the method, the high-low-pressure turbine transition flow channel profile equation is built based on the Bezier curve to optimize the high-low-pressure turbine transition flow channel, the defect that the existing method is not suitable for an urgently-expanded flow channel with the larger expansion angle is overcome, and practicability is high.
