Patent MX-171031-B (MX)
Inventor: HERBST ROBERT J
IPC: C02F1/46
Filed: 1988-06-08
Abstract: An electrolytic system (1) for treating aqueous solution which passes the solution along an inner helical insulator (15) wrapped around a centrally located anode solid rod (3) and an enclosing inner cathode tube (17), then along the inner cathode tube (17) wrapped or spaced with another helical insulator (19) and an enclosing outer anode tube (23). The solid rod (3) can be replaced with an innermost tube (45) in order for the solution to initially pass through a cathode portion of the system. Also, an innermost cathode tube (56) can have a plurality of apertures (58) as passageways for the solution. A DC voltage is applied, in one direction or in sequential fields of different directions, across the plurality of metal rods and tubes, thereby effectively removing both suspended materials and dissolved solids from the aqueous solution to be treated. The power required form the DC voltage source (35) can be decreased by treating specified tubes or rods.

Filed: 1987-09-28
Abstract: A data processing system executes two instruction sequences in an order determined in advance. With the aid of instructions a main memory (1) common to both sequences is activated for data information reading/writing. Increased data handling capacity is achieved in the following manner: both sequences (5) are executed in parallel to start with. During execution of the first sequence the main memory is prevented from being activated for writing due to the second sequence write instructions (37, 39, 41). A write address and data information included in a write instruction (49, 50) associated with the second sequence are intermediate-stored. The intermediate-stored write address is compared with the read addresses (68, 70, 73) of the second sequence, and data information is prevented from being read from the main memory upon likeness in addresses, the intermediate-stored data information (37, 38, 39, 41, 44) being read instead. An address included in a read instruction associated with the second sequence is intermediate-stored if this address has not been previously selected in conjunction with a write instruction associated with the second sequence (49, 50). The intermediate-stored read address is compared with the write addresses of the first sequence and execution of the second sequence (66, 74, 76) is restarted upon likeness in addresses.

Title: Process for treating objects made of magnetically soft alloys
Inventor: DUBININ G N
IPC: C22F1/00
Filed: 1979-06-05
Abstract: The invention relates to a process for treating objects made of magnetically soft alloys, which can be used in radio-electronic devices, relays, communications devices, opto-mechanical systems and automatic control systems. The process is based on the saturation of the surface of the object with chromium applied with the aid of a chromium-providing powder mixture at a temperature of at least 800 degrees C, and on the heating of the object at a rate that is not faster than the rate of crystallization of the metal and the rate of diffusion- based saturation of the object. The latter is cooled at a rate that is very nearly the same as the rate of phase transition and the rate at which the magnetic structure of the metal is formed in the object, such as a rate of 20-200 degrees C per hour, until a temperature is reached that lies below the Curie point. The surface of the product is saturated with chromium in a neutral gaseous medium in order to improve and stabilize the magnetic properties of the object and improve its resistance to corrosion and wear and tear. <IMAGE>
