Title: Stagewise fluidized roasting of materials containing arsenic and antimony as well as roastable sulfur
IPC: C01B17/52
Filed: 1969-03-01
Abstract: A process for the production of a gas containing sulphur dioxide consisting of the stagewise roasting of arsenic- and/or antimonycontaining sulphidic materials (e.g. iron pyrites) with a gas containing oxygen in a fluidized bed, wherein there is provided a separate supply of the oxygen containing gas for (and a separate withdrawal of the roaster gas from) the preroasting, and after roasting stages, is improved when using material having a particle size up to 100 microns (e.g. flotation concentrates) by reducing the throughput of both the material and the oxygen to the preroasting stage to 25-45% of that which would be used if material having a particle size up to 10 mm were used, the throughput to the after-roasting stage not being so reduced but the reduced output from the pre-roasting stage being supplemented by the use of an auxiliary pre-roasting furnace. Preferably conditions are a 30-40% reduction compared to material having a particle size of 6 mm. used. In the example ion pyrites are preroasted to FeS.3Fe 3 0 4 at 850-900 C. and after-roasted to Fe 2 O 3 at 750-800 C.

Patent ES-366658-A1 (ES)
Title: Process for the production of a methane-containing gas
IPC: C07C1/00
Filed: 1969-04-30
Abstract: A gas containing a high proportion of methane (e.g. 90 percent or more) is produced by (i) reacting a preheated mixture of steam and the vapor of a predominantly paraffinic hydrocarbon feedstock having a final boiling point of not more than 300 DEG C. in the presence of a steam-reforming catalyst to give a gas containing methane, hydrogen, carbon oxides and undecomposed steam, the reaction zone being cooled by a heat exchanger (ii) reacting the stage (i) product gas in the presence of a methanation catalyst to increase the methane concentration, the reaction zone being cooled by a heat exchanger, and (iii) removing steam and optionally carbon dioxide from the gas leaving stage (ii). Both stages are operated at as low a temperature as possible to maximize the production of methane. The heat exchangers are preferably fluid-cooled internal heat exchangers. The fluid coolant may be water or steam. Water may be used in stage (iii) to remove (by cooling) steam passed into the stage (ii) heat exchanger and converted into steam passed into the stage (i) heat exchanger and then used as the process steam.
Patent ES-368816-A1 (ES)
Title: Strap gripper for strap tensioning tool
IPC: B65B13/02
Filed: 1969-06-26
Abstract: A strapping tool comprising a tensioning mechanism 12 and a sealing mechanism 14 mounted on a frame 10 for tensioning and securing a strap 18 about a package 20, is provided with pivoted first and second gripping members 22 and 26, the first gripping member having a roughened, e.g. serrated surface, adapted to squeeze a free end of the strap against a foot provided on the frame when swung in a first direction (clockwise) and adapted to release the said strap end when swung in a second direction (anti-clockwise) and the second gripping member 26 having a roughened, e.g. serrated, surface adapted to squeeze the portion of the band or strap leading to the tensioning mechanism 12 against a smooth surface on the first gripping member when the second gripping member is swung in the said second direction (anticlockwise) and adapted to release the said strap portion when swung in said first direction. The gripping members are mounted on concentric shafts 28, 30, each of which carry a cam 40 or 42 for actuation by a handle 50 to move the gripping members in respective opposite directions of rotation to grip or release the respective strap portions, a spring 44, Fig. 6 (not shown), being provided between the respective shafts so that the gripping members are biased together towards the strap-gripping positions. Handle 50 is initially moved downwards to the dotted-line position thereby moving the first gripping member and then subsequently the second gripping member to their non-gripping positions, the consequential action being achieved by a cam 52 actuating the first gripping member prior to a cam 54 actuating the second gripping member through a push-rod 56. The strap portions are placed between the respective grippers, and the pressure on handle 50 released sufficiently so that spring 44 acts to urge gripper 22 to the gripping position whilst gripper 26 is retained in the non-gripping position. After tensioning the strap, pressure on handle 50 is released to permit gripper 26 to move to the gripping position. Tension can then be released in the strap portion between the grippers and the tensioning mechanism to permit sealing of the overlapped strap portions whilst the strap is held in a tensioned condition about the package.

Title: Improvements in or relating to sealing joints for vacuum treatment enclosures
IPC: F27B5/04
Filed: 1969-06-26
Abstract: A sealing joint for a vacuum treatment enclosure, e.g. for heat treatment of elongate metal articles, comprises a bath of liquid metal 3, divided into two regions by a wall 11 for isolating the interior of the vacuum enclosure from the atmosphere or a region of subatmospheric pressure. A wire 1 to be treated may be guided through the bath 3, e.g. of indium or gallium, possibly heated by electric means 5, by rollers 4, 15 to enter a treatment zone 10. Heating means 12 may preheat the wire 1, while brushes 7 remove adhered bath metal nitrogen, argon, CO 2 &c., may be introduced through a valve 14 to prevent oxidation of the metal 3. A similar sealing joint, Fig. 3 (not shown), may be provided at the exit end of the zone 10. To reduce the pressure difference across the joint, a second joint, e.g. comprising a water bath, may be provided on the atmospheric side of the first, Fig. 4 (not shown), the article 1 passing through a region (23) of intermediate subatmospheric pressure. Vaporization of the water may be avoided by blowing a cold gas (34) into the region (23) and/or circulating the water through a cooler (37).

Patent ES-376545-A1 (ES)
Title: Frequency modulation signal demodulator
IPC: H04N1/40
Filed: 1970-02-13
Abstract: and H3T A frequency discriminator of the type in which nominally constant width pulses are produced is characterized in that the constant width pulses are produced by a circuit which responds to input pulses occurring during the generation of the constant width pulses to increase their width. Incoming frequency modulated signals are fed via a pre-amplifier and equalizer, Fig. 2, to a limiter stage Q6, Q7 to produce a square wave signal, which is differenti- ated at C 18 , R 28 , R 29 , Fig. 3. The resulting pulses are then rectified by the circuit Q9, Q10 to produce a train of unipolar pulses which switch on transistor Q11. During the time when no pulse occurs transistor Q11 is off and capacitor C 19 is charged to hold on transistor Q12 of Schmidt trigger Q12, Q13. When a pulse occurs C 19 is discharged through Q11 and trigger Q12, Q13 switches to its other state until capacitor C 19 recharges to the switching threshold of Q12 to reset the trigger. Any further input pulses occurring during the charging time of C 19 will discharge it again and will thus increase the duration of the output pulse. The output pulses are then integrated by the low pass filter to produce the demodulated output. A further circuit Q 19 , Q 20 , Q 15 produces a signal to inhibit Q 11 in the event of a carrier failure.

Title: Hydrostatic button bearings for pumps and motors
IPC: F01B3/00
Filed: 1972-06-16
Abstract: In axial-piston, hydraulic pumps and motors, the thrust loadings of the pistons on their bearing supports vary proportionally to pressures in the unit and also circumferentially around the bearing supports. By employing hydrostatic button bearings pressurized in "sets" around the bearing support with at least one set pressurized with the unit's inlet pressure and another "set" pressurized by the unit's outlet pressure, improved bearing performance is achieved. Also, certain surface configuration forming the sills and recesses of the individual buttons can enhance bearing performance.
