Patent ES-8201688-A1 (ES)
Title: Devices for automatically adjusting ignition advance
IPC: F02P5/145
Filed: 1981-04-02
Abstract: The ignition advance of an engine is controlled in response to engine speed and inlet manifold depression. The inlet manifold depression is sensed via two ducts 13, 21 each provided with a calibrated orifice 14, 22 and connected to the chamber 7 of a pneumatic actuating device 6. At low loads the throttle 2 occupies the position 2b between the two ducts so that a relatively reduced advance of the ignition is obtained by movement of the rod 5. At high loads, both ducts are downstream of the throttle and maximum advance is provided.

Title: Continuous process for the removal of chromium from waste waters and valorization of the recovered chromium
IPC: C02F9/00
Filed: 1981-05-08
Abstract: A continuous process is described, wherein chromium-containing waste waters are subjected to continuous hot treatment with acetic acid or with alkaline acetates and alkaline hydroxides at a temperature from 40 DEG C. to boiling point and at atmospheric pressure, at a pH higher than 6.5, preferably between 7 and 10, particularly about 7.5. Thus, a "sandy" type of chromium hydroxide is obtained, having a titer in Cr2O3 of 20 to 40% by weight, which quickly filters, is easily soluble in acids, and thereby affords an easy valorization both as a tanning agent and as a raw material for preparing other chromium compound.

Title: Wedge actuated drum brake assembly.
IPC: F16D65/14
Filed: 1983-02-04
Abstract: A wedge actuated drum brake assembly uses a wedge-shaped actuating rod and a roller cage slidably mounted thereon to transmit actuating forces from a fluid pressure actuator to a pair of friction elements. The actuating rod and roller cage are provided with a compression spring between the rod and the roller cage and an extension spring between the roller cage and the housing within which the actuating rod and roller cage are movably mounted. The extension spring opposes the compression spring during initial movement of the actuating rod to thereby cancel the spring forces acting on the cage. A flexible boot interconnects the rod and the wall of the housing and includes a bead that is clamped with the end coil of the extension spring between a shoulder on the housing and a portion of the fluid pressure actuator that extends into the housing.

Title: Filter-press with clamped filter-plates, which are disengageable one by one in successive order after dislocking the clamping means.
IPC: B01D25/172
Filed: 1983-02-10
Abstract: A filter press with filter plates slidable individually by a transport element has on each filter plate a locking hook which cooperates for locking with a locking bolt of the adjacent filter plate. A pivotable blocking element, which in the blocked position, positively blocks the locking hook locking this filter plate against unlocking and is connected to an actuating member which projects into the path of the transport element so that immediately before the latter takes along the relevant filter plate it engages the actuating member and thus pivots the blocking element into a release position so that the filter plate is separable after release of the locking hook. Each respective filter plate to be slid thus remains positively locked to the as yet unopened plate stack until immediately before it is taken along by the transport element and cannot become separated from the stack accidentally. The blocking element is preferably in the form of an arm of a double-armed lever and is swingable downwardly by its own weight. The other arm of the double arm lever is an actuating member which precedes a driver for the filter plate to be engaged by the transport element.

Patent ES-8603554-A1 (ES)
Title: Closed FCC cyclone catalyst separation method and apparatus.
IPC: B01J8/00
Filed: 1984-09-05
Abstract: The present invention involves an improved process and apparatus for the fluid catalytic cracking (FCC) of hydrocarbons. In such an invention, the output of a reactor riser zone is fed to a riser cyclone separator, a primary cyclone separator, and secondary cyclone separators, connected in series within a single reactor vessel. The riser cyclone separator is connected to the primary cyclone separator by a conduit, which prevents random post-riser thermal cracking of the hydrocarbons after they exit the riser cyclone separator. The conduit contains an annular port to allow stripping gas to enter the conduit to improve the separation of hydrocarbons from catalyst. Catalyst separated in the riser cyclone separator can drop through a riser cyclone dipleg and can then pass through a dipleg seal which comprises a seal pot or catalyst held around the dipleg. The conduit is formed by two overlapping parts, one having a larger diameter than the other to form the annular port and packing or spacers may be used to align and space the overlapping parts.

Title: Hydrometallurgical method for treating valuable metal raw materials containing chlorides and fluorides
IPC: C22B3/08
Filed: 1984-10-19
Abstract: The purpose of the method is to remove chlorides and fluorides from a valuable metal raw material by leaching the raw material into sulphuric acid solution and by crystallizing the valuable metal sulphate selectively out of the solution.
