Inventor: ZARDI U
IPC: C07C239/00
Filed: 1977-09-09
Abstract: In a urea producing method by synthesis, the improvement which consists in feeding liquid ammonia in excess to the reactor so that a urea solution which contains ammonium carbamate is produced, the carbamate is decomposed in a high-pressure decomposer and the stripping agent is an inert, oxygen-containing gaseous stream, the carbamate decomposition products are sent to a high pressure condenser and ammonium carbamate is formed, whereafter the carbamate is separated from the inerts and the solution of urea coming from the high-pressure decomposer is fed to a medium-pressure decomposer which is fed through its bottom with inerts. The heat for operating the medium-pressure decomposer is a hot condensate from the high-pressure-decomposer-heating steam, and the products of decomposition of the carbamate coming from the medium-pressure decomposer are sent to a medium-pressure condenser together with a solution of ammonium carbonate coming from the low-pressure sections of the installation. Virtually pure, nonpolluting waters can be discharged from the installation.

Abstract: Methods and apparatus for generating and transmitting seismic signals for the purpose of seismic exploration are disclosed. The signals are force pulses shaped to have a spectrum constrained to the range of frequencies which are necessary for penetration to desired depths within the earth and for resolution of the geological reflection surfaces therein. These pulses are provided in a non-repetitive or aperiodic train, constructed to produce a transmitted energy spectrum whose mean energy extends smoothly at a substantially constant level over the spectrum frequency range, notwithstanding that the repetition frequency of the pulses may be swept over a frequency band much narrower than the spectrum range. The transmitted spectrum can exhibit an auto-correlation function having a major lobe which is predominant over any side lobes, corresponding to a desired level of resolution of the geological reflection surfaces.

Abstract: The invention relates to a ferry berths device, especially for car traffic, and having a travelling bridge 1 arranged such that it is adjustable to and fro along a ramp 2, which ramp extends from the beach downwards and outwards into the water to allow the docking point of the ferry to be adapted to different water levels. Known ferry berths having a travelling bridge are certainly cheaper to produce than the more complex drop-type berths, but have proved difficult to use with larger and modern ferries of deeper draught, since the ramp ends up extending too far out into the water and causes obstruction. The object of the invention now aims to remedy this drawback and this is principally achieved by the ramp being arched or curved upwards, i.e. upwardly convex. <IMAGE>

Abstract: The invention relates to a continuous laminating machine for exerting a surface pressure on a moving web of material by means of pressing belts, which roll against the stationary support structure of the machine via rod- shaped roller bodies. Between the supporting bodies, which are connected by means of clamping plates, and the two steel belts are thereby arranged cylindrical rods alternating with distance profiles matching said rods, in such a manner that the deformation forces emerging from a material web to be compressed between the steel belts, from the roller bodies under rolling friction, are led in to the supporting bodies and to the clamping plates connecting same. The toothing at edges of the steel bands engages in the outer toothing on the torque transmitting hole gear wheels, which take over the driving and the sideways guiding of the steel band running between same. <IMAGE>

Abstract: A section constituting an outer longitudinal element or moulding of a false ceiling or false wall, is constituted substantially by an angle of which the vertical flange is applied against a wall and the horizontal flange presents a shoulder extending towards the vertical flange to ensure fastening of a hook-shaped edging fast with a sheet of plastics material or cloth maintained stretched by the section. The horizontal shoulder defines, with the horizontal flange, a groove whose cross section is in the form of a U open towards the vertical flange. A cant provided in the angle constituting the section joins the horizontal flange inside the U-groove so as to define, between this cant and the shoulder, a narrow passage of width slightly larger than the thickness of the part of the edging which is engaged in the U-groove.

Abstract: In order to enable a piston cylinder unit 1,2 with air entry through a hollow shaft 6, to be operated in either mode of operation with a single type of shaft, it is proposed in accordance with the invention to manufacture the shaft 6 in three parts, namely an upper air inlet portion 6a, an intermediate portion 6b which provides access for air to the cylinder via one or more apertures 18, and an operating end portion 6c. These three parts are threaded together and sealed by seals 21 and 24. Captive nuts 3 and 8 are provided at both ends of the cylinder so that the cylinder may be attached to a yoke 4 by either end, with the opposite end carrying a bearing 9 for the air inlet portion 6a of the shaft. If it is desired for the piston to operate in the opposite mode of operation, the portions 6a and 6c are interchanged and the cylinder is attached to the yoke using the captive nuts 8 rather than the nuts 3.

Abstract: According to the method of the invention, samples undergoing analysis for sorting are irradiated one by one in order to excite X-ray fluorescence. In order to take into account the background radiation, the quality whereof varies according to the frequency of the excited radiation, the radiation peak intensity I1 is measured, as well as the respective intensity I2 is measured at the same point of the radiation spectrum but in an essentially wider frequency range than the radiation peak. On the basis of the measured intensities I1 and I2 are defined the intensities of the X-ray fluorescence F and the background radiation T, and the ratio of these two is used as the selective criterion when sorting the analyzed samples.
