Title: Method and apparatus for synchronising the phase of a transit exchange in a digital telecommunication network.
IPC: H04Q/
Filed: 1983-03-09
Abstract: The transit exchange has a signal-controlled oscillator with an output signal which depends on the collectively weighted phase difference between the local exchange clock and the clock of the other exchanges. To avoid phase jumps, a signal corresponding to the phase difference is sampled, the sampled values differentiated, the differentiated values compared with a limit value employing a phase jump when exceeded, and when this value is exceeded a signal with the control signal's highest value but with opposite sign is added to form a compensation signal, this compensation signal being added to the differentiated value, and after possible weighting the differentiated value is summed with corresponding differentiated values from comparison with the phases of other links, and the sum value integrated to obtain a resulting control signal.

Title: Process for dehydrogenating a dehydrogenatable hydrocarbon
IPC: B01J23/02
Filed: 1983-12-16
Abstract: This invention relates to a process for the dehydrogenation of dehydrogenatable hydrocarbons. More specifically the invention relates to a process for the dehydrogenation of dehydrogenatable hydrocarbons in which the hydrocarbon is subjected to a dehydrogenation stage in the presence of a dehydrogenation catalyst followed by a selective oxidation stage in which the product mixture originating from the dehydrogenation stage is treated in the presence of certain compositions of catalytic material described in greater detail below in which the hydrogen which is present originating in the dehydrogenation stage is selectively oxidised with minimum oxidation of the hydrocarbons. Using the special selective oxidation catalyst, dehydrogenated hydrocarbons can be obtained in relatively high yield, while maintaining the stability and activity of the catalyst, thus avoiding the need to regenerate or change the catalyst and thus increasing the economic viability of the dehydrogenation process.

Patent ES-8505277-A1 (ES)
Title: Hammer drill apparatus
IPC: B23B31/173
Filed: 1984-09-03
Abstract: A drill chuck is rotatably driven by a drill spindle, on which the drill chuck is mounted by a plurality of radial lugs so as to prevent relative rotation, these lugs engaging in catch recesses in the drill chuck, which allow axial free play of the drill chuck on the drill spindle, unless prevented by adjusting a shift member mounted adjustably on the drill chuck without contact with and with axial clearance from the drill spindle. The lugs are rigidly connected with the drill spindle and lie axially against adjacent opposing shift member surfaces on both sides of the drill chuck. According to the rotary position of a shift member the lugs press directly on the adjacent shift member surfaces preventing axial free play of the drill chuck on the drill spindle and transmitting the drilling force or they lie opposite indentations in the shift member with clearance from the shift member surface so as to allow axial motion free play. As a result during drilling the shift member does not bear the force of the drilling.

Abstract: The invention relates to a suspension system for motor vehicles of the type including a transverse bar (8) connected at its ends to the central parts of two longitudinal arms (2), each of which is articulated at one end to the body of the motor vehicle about a transverse axis (4), and at its opposite end has a bearing (6) for a wheel. In this invention, the said transverse bar is constituted by a tublar component which has a substantially circular, open cross-section and is fixed at each end in a cooperating seat in the respective longitudinal arm (2) by means of a series of radial bolts (14) which engage that part of the transverse bar (8) diametrally opposite the aperture in the bar itself. Within each end of the transverse bar (8) there is a tile-shaped locking element (17) provided with a series of nuts (18) which are engaged by the ends of the said radial fixing bolts (14). This tile-shaped element which may, for example, extend through an angle of about 180 DEG , has a cross-section the thickness whereof decreases progressively from its centre towards its ends. Thus the ends of the bar (8) are locked in the respective longitudinal arms without causing discontinuous stresses in the bar itself.

Title: Process and device for draining a pile of a wet granular material
IPC: B01D43/00
Filed: 1985-01-28
Abstract: The process comprises the following operations: - bringing wet material to form a pile 4 so as to allow the water to flow away by percolation over the height of the pile 4 while saturating the material situated in the lower part of the latter and causing free water to appear - removal of the free water from the lower part of the pile so as to prevent the free water level from rising - removing drained material from a "withdrawing" level which is sufficiently raised above that of the free water. It is characterised in that the pile 4 being produced on an area 1 for draining water, the part 6 of the pile situated between the draining zone and the withdrawing level, called a passive zone, is employed as a filtering zone used for protecting drains placed in the draining zone and preventing their blocking, this passive zone 6 being reserved for the draining of a number of piles deposited on it successively, before being replaced when it begins to be blocked.
