Abstract: A catalyst for the liquid phase hydrogenation of acetophenone to phenyl methyl carbinol having improved physical strength and superior selectivity to the desired product having a composition expressed as oxides consisting essentially of: (a) a barium-copper chromate containing 30-55 wt % CuO, 30-57 wt % Cr2O3, and up to 16 wt % BaO and (b) 1-13 wt % ZnO relative to 100% by weight of said barium-copper chromite. In a preferred embodiment 0.15-1.7 wt % MgO relative to 100% by weight of said barium-copper chromite is included. The zinc compound may be added by solution impregnation of the barium-copper chromite or as a powder. Preferably, the catalyst is prepared by combining into a wet paste a barium-promoted copper chromite and a zinc compound and preferably also magnesium chromate, followed by drying the paste and then calcining the dried mixture. After calcination, the catalyst typically is pelletized for use in a fixed bed reactor. The magnesium chromate may be added directly to the mixture as the powdered compound.

Patent ES-8106215-A1 (ES)
Title: Polyphase electric machine having controlled magnetic flux density
IPC: H02K17/12
Filed: 1980-08-13
Abstract: Prior art design characteristics result in motor flux density being maintained during normal operation at non-optimum levels. Accordingly the motor size must be substantially larger than would theoretically be necessary in an ideal motor in order to obtain the desired output horsepower. In the invention a capacitor (16) is connected in series with each stator main winding (10), (12), (14). The voltage across the capacitor (16) together with the motor input voltage periodically causes the volts-second capacity of the stator core to be exceeded causing a periodic change from high to low flux density which results in a high average flux density. Control windings (18), (20), (22) are wound on the stator core adjacent to each stator main winding (10), (12), (14) thus creating main and control winding pairs. The control windings (18), (20), (22) are wound in the opposite direction from the main windings (10), (12), (14) so that the main winding current and the control winding current of each pair is in-phase at no load and increasingly out of phase as the load increases resulting in a low flux density at low load and increased flux density at higher loads. The flux density is optimized for the particular load condition which in turn minimizes the line current for a particular load, thus minimizing the motor size required for a desired horsepower. An increase of starting and breakdown torque in the invention is achieved by placing the centers of the poles of the control windings as close as physically possible between the poles of the main windings.

Patent ES-8205932-A1 (ES)
Title: Radially inward flow turbine.
IPC: F02B37/22
Filed: 1981-02-20
Abstract: A radially inward flow turbine has an annular nozzle arrangement (25) through which pressurized gas is passed in a generally radially inward direction from an annular inlet passage (24) to a bladed turbine wheel (16). The nozzle arrangement (25) is defined by parts (26, 28) of the turbine housing (10) which are relatively displaceable axially of the turbine for varying the dimensions of the nozzle arrangement (25) and hence for varying the turbine air pressure ratio. In order to enable the dimensions of the nozzle arrangement (25) to be varied without problems of seizure of the relatively displaceable parts, the latter parts are in the form of relatively displaceable rings (26, 28) which each carry a respective annular array of angularly spaced vanes (36, 34) for directing the gas flow from the annular inlet passage (24) onto the turbine blades (20). The angular positions of the vanes (36, 34) on the rings (26, 28) are such that the vanes (34) on the ring (28) are interposed with the vanes (36) on the ring (26). Relative axial displacement of the rings (26, 28) varies the extent of axial overlap of the vanes (36, 34) when they are in their interposed state.
