Abstract: A method for recovering and purifying a waste sulfuric acid solution includes steps of: adding a coupling agent (m) to the waste sulfuric acid solution, and mixing uniformly to obtain a mixture (a); adding a coupling agent (n) to the mixture (a), and mixing uniformly to obtain a mixture (b); and adding a synergistic agent to the mixture (b), thoroughly stirring and filtering to obtain a purified sulfuric acid solution. The method adds the coupling agent and the synergistic agent to the waste sulfuric acid, and a removal rate of the heavy metal ions in the waste sulfuric acid can reach 99%. The purified sulfuric acid solution can be recycled. The method is simple to operate, and can remove a wide variety of heavy metal ions such as copper, zinc, lead, mercury, nickel, iron, cadmium and manganese in the waste sulfuric acid.

Abstract: A shape-restoring device and a restoring method for distorted filmstrips are proposed for restoring filmstrips that are distorted due to vinegar syndrome. During the implementation of the method, the air compressor is started such that pressure reaches 0.6-0.9 MPa; three-way valves are regulated so as to introduce pressure into film-clasping cylinders and pressing-plate cylinders via diverter valves; the cylinder spindles of the film-clasping cylinders move the upper collets fixedly connected therewith, for fixing filmstrips; the cylinder spindles of the pressing-plate cylinders move the pressing plate fixedly connected therewith such that the binding underlay on the lower surface of the pressing plate contacts the heating plate; in this way, pressuring, heating and restoring are carried out. Through steps of pressing, heating, fixing filmstrips, shape-restoring and transporting the distorted filmstrips under the pressure of 0.5-0.8 MPa and the temperature of 80-90° C.

Abstract: A central computer of a telecommunications company handles an incoming call from a caller. The telephone number of the caller is checked against a white list or blacklist and handled accordingly. If the caller is unknown, a question is played to the caller (optionally selected randomly) along with a number of possible answers. The answers are presented randomly, associated with random identifiers, etc. If the caller selects the correct answer then the call is routed to the receiver's telephone. If not, then the call is terminated or other action taken as specified. The incoming call may also be handled by a mobile telephone or computing device at the user's home or business. The mobile telephone may alert the user when answering the incoming call or wait until the question is answered correctly before ringing the telephone.

Abstract: A user generates a pattern in a matrix (or two-dimensional grid) and enters a user name and an associated password. This username, password and pattern are stored locally on a computing device or are transmitted to a remote computer server for later authentication. Upon authentication, an input matrix is displayed. The user enters the password into the matrix in the form of the pattern, and also enters the username. The computer retrieves the previously stored pattern and password with the username. The previously stored pattern is used to read the input password from the input matrix. A match with the stored password indicates authentication. Alternatively, the input matrix only includes the pattern and password is entered separately. The input matrix may also be filled with random characters to improve security. The stored pattern is compared to the input pattern using image analysis or by comparing a set of coordinates.
