Abstract: An electrode, which may be used as an anode in a Hg cathode cell for the electrolysis of brine, comprises a support material in the form of a "valve metal" carrying on at least a part of its surface a layer of an "operative electrode material" in combination with an "inorganic glaze". "Valve metal" means Ti, Zr, Nb, Ta, W or an alloy comprising more than 50% by weight of one of these metals. "Operative electrode material" means an electroconducting material which is active in transferring electrons to or from the ions of an electrolyte and which is resistant to electrochemical attack. The material may be a platinum metal (i.e. Pt, Rh, Ir, Ru, Os, Pd or an alloy of two or more of these metals) and/or oxides thereof. "Inorganic glaze" means an inorganic oxide or a combination of such oxides which has been laid down by solidification in the vitreous condition from the molten state. The electrode may be made by depositing on the valve metal a coating of the operative electrode material, applying over the coating a layer of an inorganic glazing composition and melting the glaze. Alternatively, both the operative electrode material and the glazing composition may be deposited in a single step from a suspension containing particles thereof. The glaze may comprise silica, titania and zirconia. The glaze may be produced by coating the electrode with an aqueous sodium silicate solution optionally containing titania and then firing the coating. In an example, Ti was etched in oxalic acid coated with Ru by painting on a mixture containing ruthenium chloride, isopropyi alcohol and, as reducing agent, linalool and then heating at 300 C. in air to dry the Ru coated Ti was then heated in air at 450 C. to oxidize at least the outermost part of the Ru layer glass enamelling slip was applied and melted by heating at 590 C. The slip consisted of PbO, B 2 O 3 , SiO 2 , CdO, Na 2 O, kaolin and H 2 O.

Title: Process for the purification of synthetic calcitonins
IPC: C07K1/113
Filed: 1974-12-12
Abstract: Peptides of the calcitonin type when obtained by synthesis can be purified in a simple manner by forming inner salts, which precipitate from aqueous solutions of salts of the peptides with acids or bases when these solutions are adjusted to the isoelectric range. Impurities remain in solution, while the inner salts separate practically quantitatively. The precipitation is completed after several hours. The peptides can then be recuperated by treatment with an acid, especially a therapeutically suitable acid. The process affords products which are superior to those obtained by purification methods hitherto known and gives higher yields. Other long-chain peptides such as ACTH, insulin or glucagon cannot be purified in this manner.

Patent ES-443641-A1 (ES)
Title: Automatic gas analysis and purging system
IPC: G01M15/10
Filed: 1975-12-18
Abstract: The contaminants in the exhaust gas emissions from a motor vehicle such as carbon monoxide (CO) and hydrocarbons (HC) are analyzed and the concentration of the contaminants together with other pertinent data is displayed in a digital manner. The exhaust gas emissions are fed into a sample cell contained within a nondispersive infrared analyzer and the absorption of an infrared radiation beam at selected wavelengths by the gas within the cell is measured. A reference cell containing a reference gas is also positioned in the infrared radiation beam path. By means of a rotating chopper disk positioned in the light path, the infrared radiation beam passes alternately through the reference cell and the sample cell and is focused at a plurality of detectors which are each sensitized to a narrow wave band by a filter and which receive the alternate sample cell and reference cell radiation pulses. Synchronization of the system is provided by a notch in the chopper disk which passes alternately between three light sources and associated photoresponsive devices. Automatic span correction is obtained by an automatic gain control circuit which maintains the reference cell output at a predetermined amplitude. The sample cell is initially filled with ambient air by a gas transport system. By measuring the sample cell and reference cell outputs with ambient air in the sample cell, and then measuring the sample cell and reference cell outputs with exhaust gas in the sample cell, a ratio can be computed which is proportional to the amount of the contaminant. Computation of the ratio in this manner results in automatic zeroing and spanning of the system. The computed ratio is then calibrated for nonlinearities in the system, and linear corrections are made for variations in ambient pressure and for variations in the temperature of the gas passing through the sample tube. Provision is also made for assuring that the vehicle being tested has achieved a predetermined engine speed and that no blockage has occurred in the gas transport system when the measurements are made. After the exhaust gas has been analyzed it is replaced in the sample cell with ambient air to prevent contamination of the system optics from the exhaust gas. A sapphire window is positioned in front of the infrared source to reduce changes in source temperature by air currents produced by the rotating chopper disk.

Title: Method and means for the detection of deadlock among waiting tasks in a multiprocessing, multiprogramming CPU environment
IPC: G06F9/52
Filed: 1978-10-10
Abstract: The wait relations among N tasks in a multiprocessing, multiprogramming CPU environment are conformed to a vector of N+1 fields recording which tasks in a system are active and upon what other task any given task directly waits. The vector may be stored in a global register. Positions 1 through N are assigned to the N tasks such that a value p in position r means that task r is waiting directly on task p. One value j of the possible values 0,1,2, . . . , N+1 is designated to indicate an active task. Position j always shows the value j. Without loss of generality and to facilitate the discussion j is assumed to be 0. Thus, the value 0 in register position r means that task r is not waiting and position 0 always has the value 0. The presence of any deadlocks (closures) among the wait relations can always be detected by the computing system by making repeated translations of the vector fields within and upon themselves in no more than log2(N+1) iterations. In this regard, log2(N+1) denotes the smallest integer equal to or greater than the base 2 logarithm. The translation of fields within and upon themselves means that for each global register position r containing pointer p, then the contents g of register position p are substituted as the new contents of position r for the iteration 0</=r, p, g</=N.

Title: System using integrated circuit chips with provision for error detection.
IPC: G06F11/00
Filed: 1979-06-13
Abstract: The invention provides data processing duplication and internal error checking within an integrated circuit chip at intermediate points along the logic chain. In one aspect of the invention, duplicate functional logic within the chip is utilized together with multiple fault detectors to provide error checking of the primary logic chain, mechanical interconnection failures, and power and clock pulse checking. The detectable failures are both transient and hard failures. Other problems are in addition resolvable by utilization of duplicate complementary logic in place of duplicate functional logic, such other problems including chip contamination during manufacture, mask problems and functional design problems. The multiple fault detectors provide a multiplicity of error signals which are multiplexed within the chip to produce encoded output error signals each of which designates the fault which has been detected within the chip. These encoded error signals are routed to a special error handling chip which receives encoded error signals from a large number of places, such as a group of chips or circuit cards, and by correlating the information contained in the encoded error signals is able to identify the source of the error as a particular VLSI chip, the interconnections between VLSI chips, a particular circuit card, a power supply line to a circuit card or a group of such cards, or other faults.
