Patent ES-357517-A1 (ES)
Title: A control system for hydraulic apparatus
IPC: F15B13/01
Filed: 1968-08-24
Abstract: The actuating lever handles 11, 13, 15 of valves, particularly for controlling the advancing and setting of hydraulic mine roof supports, are interlocked for the programming of the operation by an apertured key-plate 16. As shown, each pair of handles a, b, c is located in a distinctive pair of slots as shown, and each handle has three positions, 1 where the associated prop is braced, 2 a neutral position, and 3 where the prop is retracted. The plate is movable in guides 17 by a lever 18 into three positions in one of which, as shown, the pair of props a are locked in the braced condition, props b can only be retracted, and props c are normally retracted but can be braced if desired. In a mid position of the plate the roles of the top and bottom pair are reversed whilst the middle pair can move between positions 1 and 3, whilst in another extreme position the top and middle pairs are locked. To avoid moving the plate quickly before the props have been fully extended and set, a spring-loaded pressurerelief valve, Fig. 4 (not shown), is located in series with at least some of the valves. The relief valve member (31) is spring-loaded through a surrounding sleeve (33) having a pressure balancing extension stem (34). The fluid has access to the sleeve interior through openings (40, 401).

Title: Shock Absorber
IPC: F16F9/49
Filed: 1968-10-21
Abstract: A shock absorber has an auxiliary cylinder and an auxiliary piston. The auxiliary cylinder is located at the piston-rod end of the shock absorber's main cylinder the auxiliary piston is slidably mounted on the piston-rod of the main piston and is provided with at least one axial slot through which the passage of fluid is prevented when the main piston forces the auxiliary piston into the auxiliary cylinder and a projecting ring on the piston-rod is provided to engage the auxiliary piston. In an embodiment a shock absorber has telescoping tubes 5 and 6, the former having an end cap 7 with an attaching member 8 attached thereto and the latter being closed by a cap 12 connected to an attaching member 13. The cap 7 supports a piston-rod 9 which has a twoway valved piston 23 slidable in a cylinder 11. The latter forms an annular reservoir 10 with the tube 6 is connected to an auxiliary cylinder 72 which is also connected to a piston-rod guide 16 has a helical baffle 62 therein for eliminating turbulent flow and is secured to a head 44 of a double-acting valve 43. The auxiliary cylinder 72 receives an auxiliary piston 65 when the latter is raised by the upward movement of the piston 23, the auxiliary piston 65 being slidably mounted on the pistonrod 9. Cushioning of the piston 23 is therefore effected by means of fluid flowing between the adjacent walls of the auxiliary cylinder 72 and the auxiliary piston 65. When the piston 9 moves downwardly the auxiliary piston 65 remains in the auxiliary cylinder 72 until a ring 67, which is mounted in an annular slot 68 in the piston-rod 9, engages a slot 70 formed in the auxiliary piston 65. Before the ring 67 engages the slot 70, however, a washer 32, which is positioned between the pistons 23, 65, is forced from engagement with the piston 65 by means of a shoulder 34 of the piston-rod 9 and fluid is allowed to pass, through passages 69 in the auxiliary-piston 65, to the auxiliary cylinder 72, thus releasing the auxiliary piston 65 therefrom. In embodiments, cushioning is effected when the auxiliary piston forces fluid from the auxiliary cylinder into ball valves located in passages formed in the piston-rod guide 16 when fluid passes through additional apertures formed in the auxiliary piston 65 and when fluid passes through triangular slots in the peripheral wall of the auxiliary piston 65.

Title: Reaction zone control
IPC: C10G35/24
Filed: 1972-05-23
Abstract: The method and means of controlling the output of a multi zone reaction installation about a desired conversion level and at optimum performance conditions. An input to the reaction installation is regulated to regulate the severity of reaction in individual zones and such regulation is controlled by means including a regulatable set point for each reaction zone. The discharge effluent from the downstream reaction zone is analyzed and the signal responsive to the character of such effluent is used first to determine a performance index output signal and secondly for determining the total conversion level. An optimizer utilizes the performance index output signal to determine a first output signal for each reaction zone representing a first component of each regulatable set point. The optimizer analyzes the performance index output signal and then determines a first output signal necessary for each reaction zone to approach an optimum performance in the reaction zones. A controller utilizes the signal indicative of the conversion level of the reaction zones and determines a second output signal representing a second component of the regulatable set points corresponding to the desired total conversion level of the reaction zones. The first and second output signals are combined and are utilized as the regulatable set points for controlling the regulation of the severity of reaction in each reaction zone.

Patent ES-465675-A1 (ES)
Title: Method and apparatus for combusting cabronaceous fuel
IPC: F23C6/04
Filed: 1978-01-02
Abstract: To ensure that the process is flexible with respect to the fuels which can be used and that also the utilisation of, for example, sulphur-containing fuels is possible, the process operates as follows: A first mixture (18) of carbonaceous fuel (10) and air (14) is burned in the presence of a catalyst (25) under at least approximately adiabatic conditions. The catalyst (25) operates at a temperature which is above the instantaneous auto-ignition temperature of the first mixture (18) but below a temperature at which a noticeable formation of nitrogen oxides would take place. The waste gas from this combustion is mixed with a fuel-containing component (32) other than the first mixture (18), and the mixture (40) is homogeneously burned in order to produce a waste gas (50) which can be used as an energy source. The fuel in the said fuel-containing component (32) can - in contrast to the fuel (10) in the first mixture (18) - also be a fuel which would poison the catalyst and/or which is difficult to vaporise and to mix with air. The process is intended especially for producing a hot waste gas for use as a heat source (for example in an oven) or as an energy source (for example in a turbine installation).
