    • Keepnets allowing safer and easier release of fish retained therein with reduced danger of damage to the fish comprise a tubular net (1) open at one end (2) and closed at the other (3), the net having a rigid mouth-ring (5), a terminal ring at the closed end and a plurality of intermediate support rings (4) spaced along its length between the mouth-ring and the terminal ring. One of the intermediate rings (10) is of substantially rigid construction as opposed to the relative flexibility of the remaining intermediate rings (4). The rigid ring (10) is used as a secondary mouth when releasing the fish to reduce the length of net over which they have to be tumbled and thus the risk of damage to them. Various designs of net using this principle are described.
    • 保护网允许更安全和更容易地释放保留在其中的鱼,减少对鱼的危害的危险包括在一端(2)打开并在另一端闭合的管状网(1)(3),网具有刚性的开口环 5),封闭端的端子环和沿其长度在口环和端子环之间间隔开的多个中间支撑环(4)。 与其余的中间环(4)的相对柔性相反,中间环(10)中的一个具有基本刚性的结构。 当释放鱼类时,刚性环(10)用作次级口,以减少它们必须翻滚的网的长度,并因此损坏它们的风险。 描述了使用该原理的各种网络设计。

    • The disclosure relates to the treatment of rods made of metal, particularly to the method of reclamation of used standard length rods, such as pump rods already used in the mechanical deep-pumping extraction of oil, as well as to the product made with the help of the mentioned method. The method of remanufacturing of standard length rods includes the reheating of the rod body to a temperature favorable for the plastic treatment of the rod such as plastic deformation of the rod body under pressure. Such methods allow for the reclamation of rods of the desired geometric form and enhancement of the mechanical properties of the remanufactured rod. The technical outcome of the claimed invention consists in the reclamation of rods of the desired geometric form and enhancement of the mechanical properties of the remanufactured rod.
    • 本公开涉及对由金属制成的杆的处理,尤其涉及用于回收已使用的标准长度杆的方法,例如已经用于机械深抽抽油的泵杆,以及 关于借助所述方法制造的产品。 标准长度杆的再制造方法包括将杆体重新加热到有利于杆的塑性处理的温度,例如杆体在压力下的塑性变形。 这种方法允许回收具有所需几何形状的杆并且提高再制造杆的机械性能。 所要求保护的发明的技术结果在于回收具有所需几何形状的杆和增强再制造杆的机械性能。
