Patent ES-452237-A1 (ES)
Title: Radioreceiver switching
IPC: G08G1/09
Filed: 1976-10-08
Abstract: The circuit arrangement (7) is installed in a VHF receiver. The input of the circuit arrangement is connected to the output of the frequency demodulator (4) of the VHF receiver. The auxiliary carrier frequency is filtered out by means of a filter (10, 12). A first signal dependent on the auxiliary carrier amplitude is generated with a diode (14) and a transistor (17), and a second signal dependent on the modulation of the auxiliary carrier is generated with an amplitude demodulator (21, 22, 23). These two signals control a threshold value switch (30) if the amplitude of the auxiliary carrier and the amplitude of the characteristic range frequency in each case exceed a specific value. On receiving a traffic broadcast transmitter, the circuit arrangement initiates a switching operation which indicates to the user that his receiver is tuned to a traffic broadcast transmitter.

Title: Electrical connection of multiconductor cables
IPC: H01R4/24
Filed: 1980-05-23
Abstract: In connecting flat multiconductor cables, one cable is placed atop another to provide a matrix of zones 26-50 in which connections may be made of any conductor of one cable to any conductor of the other cable. Selection is made of one zone 26 and it is perforated at 160. An insulation-piercing connector is inserted through the perforation and crimped to provide an electrical connection between the pair of cable conductors in registry with the selected zone. Selection of further zones for perforation and connector insertion is made progressively from those zones which do not have in registry therewith any conductor which was in registry with any previously selected zone. Apparatus 158 for implementing preferred connection zone selection precludes use of connecting zones other than a singular zone 26 for connection of one conductor pair and compels use of a selective few zones individually for connection of respective other conductor pairs, thereby lessening connection error likelihood.

Patent ES-8402024-A1 (ES)
Title: Matte conversion using two parallel-connected converters
IPC: C22B15/06
Filed: 1982-12-17
Abstract: Matte conversion process employs two parallel-connected converters operated at a blowing rate corresponding to the maximum capacity of an off-gas sulphur treatment installation, each converter being blown while the other converter is being charged or discharged so that a continuous gas flow is obtained through the gas treatment equipment to a sulphuric acid plant. Pref. short blows of 20-40 mins. are employed and slag-blowing periods for one converter pref. coincide with metal-blowing periods for the other converter. - The process is esp. useful for the conversion of high quality copper mattes. An alternate blowing and partially super-imposed conversion technique is employed so that the periods between successive conversion operations in each converter are as short as possible. Thus no additional fuels are required and the amt. of exhaust gas is much less than in conventional methods, resulting in a higher SO2 level in the exhaust gas and reduced gas treatment costs. A single gas treatment unit can be used, to provide a more compact plant. DEAB- DE3245050 C High-grade metal mattes are converted in two parallel-opening converters, which are blown with alternating conveting periods, overlapping each other, so that one blowing period occurs during a charging and/or tapping period of the other, and vice-versa. Operation is such that the slag blowing period of the first converter overlaps the metal blowing period of the second. Blowing periods have a duration of 20-40 minutes and preheated air is used for slag-blowing, the temp. of which is pref. 60-180 deg.C. The plant has similar blowing ducts foro the converters, corresp. to the maximum capacity of a common S processing plant receiving process gases.
