91 results about "Antler" patented technology

Antlers are extensions of an animal's skull found in members of the deer family. They are true bone and are a single structure. They are generally found only on males, with the exception of the reindeer/caribou. Antlers are shed and regrown each year and function primarily as objects of sexual attraction and as weapons in fights between males for control of harems.

A technique for inducing ectopic antler growth through antler tip transplantation

This invention discloses a method for inducing ectopic antler growth through antler tip transplantation, belonging to the field of antler tip transplantation technology. The method includes the following steps: after anesthetizing the deer, the hair on the area to be transplanted is scraped and disinfected. Then, a wound is cut and a small pouch is made. The antler tip is then inserted into the small pouch, and the wound is sutured. This invention cuts off the tip of the newly formed or regenerated antler and transplants it to the forehead, top of the head, or leg. During the transplantation process, the skin (such as the scalp) can transform the antler tip into seed cells, giving it stem cell characteristics, thereby initiating the formation of antler stalks and antler growth, and antler regeneration. This ectopic antler, like the original antler, becomes ossified antler in autumn. The antler falls off the following spring, and a new antler, larger than the original, regenerates from the fallen antler. This transplantation method does not affect the growth of the original antler, and each deer can harvest two more ectopic antlers per year, effectively increasing antler yield.

Symmetrically fixed air-blowing pipes are connected to the bottom of the storage tank, all penetrating the top of the control box. Rotating shafts are rotatably connected to the outer surfaces of the air-blowing pipes, also penetrating their outer surfaces. When spontaneous combustion occurs inside the control box, the high temperature generated by the combustion pushes a piston upwards, triggering the rotation of the rotating shafts and rotating plates. The air-blowing pipes then open, allowing carbon dioxide from the left chamber of the storage tank to be ejected through the air-blowing pipes and H-shaped pipes. The carbon dioxide surrounds the combustion point, isolating it from oxygen and quickly extinguishing the combustion. This prevents the spontaneous combustion from expanding and ultimately damaging the power supply to the equipment inside the control box if the fire is not detected in time, thus avoiding further losses.
