When the pull moves, the movable jaw portion will be opened or closed relative to the supporting rod with the fixed jaw portion due to a change in the magnetic field between the magnets.

Abstract: The essence of the invention is an effective method for generating the multiplicative inverse in a finite field GF(p) where p is prime, i.e. for generating the modular inverse. This method is derived from the Extended Euclidean Algorithm (EEA). The method is for binary execution of operations during the process of generating the modular inverse, with respect to the lowest number of addition, subtraction and shift operations possible. The proposed method avoids redundant operations for converting odd and negative values, which are performed in methods currently in use. To achieve that, negative numbers are represented in the two's complement code, values in the control part of the EEA are shifted to the left, and a new definition of the boundary and control conditions is utilized in the procedure. Minimizing the number of additions and subtractions is desirable for calculations with large numbers often encountered in cryptography.

Abstract: The invention is a method of manufacturing construction precast elements made of porous construction materials, especially composite materials with open structure of pores, cured under normal temperatures, such as concretes, where these construction materials are formed of a mixture of aggregate and bond. Unsorted plastic waste is added into the mixture of aggregate and bond. Such unsorted plastic waste is freed from dirt, crushed and shaped into granules. These granules of plastic waste are mixed into the mixture of construction material before curing. When cured, the resulting precast element is heated to a temperature causing at least part of the granules to melt into a fully liquid state. The resulting composite element is allowed to cool. The plastic waste becomes an additional bond in the precast elements.
