Abstract: The invention provides an agent for desulfurizing crude iron and steel melts, the desulfurizing agent being based on calcium carbide containing calcium oxide. The desulfurizing agent is produced by admixing a calcium carbide melt having up to 45 weight % of calcium oxide therein with an excess of 3 to 15 weight %, based on the CaO-content of more than 45 up to 80 weight % desired for the final product, of calcium oxide. The resulting mixture is allowed to solidify and cool down to temperatures of 350 DEG  to 450 DEG  C. Next, the solidified melt is precrushed to material with a size of less than 150 mm. Particles with a size of less than 4 mm are screened off and the remaining material is comminuted, with the exclusion of moisture, to material with a size of less than 10 mm.

Abstract: A spectral shift pressurized water reactor comprising apparatus (38) for inserting and withdrawing water displacer elements (40, 82) having differing neutron absorbing capabilities for selectively changing the watermoderator volume in the core (34) thereby changing the reactivity of the core. The displacer elements (40, 82) comprise substantially hollow cylindrical low neutron absorbing rods (40) and substantially hollow cylindrical- thick walled stainless rods (82). Since the stainless steel displacer rods have greater neutron absorbing capability, they can effect greater reactivity change per rod. However, by arranging fewer stainless steel displacer rods (82) in a cluster, the reactivity worth of the stainless steel displacer rod cluster can be less than a low neutron absorbing displacer rod cluster.

Abstract: A lower non-woven layer (18) is first formed by wet process on an inclined sieve (17) by means of a first hydroformer (16, 19). Then, the water is eliminated in the hydroformer (19) and the layer is possibly partially dried in a dryer (24). A sheet (25) impregnated with an adhesive (26'), for example a latex or a synthetic resin, is then deposited and applied on the lower layer (18) so as to obtain a good bond. A non-woven upper layer (35) is finally deposited on the sheet (25) by means of a second hydroformer (30, 36). The water is also eliminated from that layer which is appropriately partially dried (dryer 42). Thereby, a three layer sheet is provided, with optimum felt covering and reciprocal adhesion of the different layers. This sheet (43) is then forwarded to a drying stage (44) where the drying is completed, and possibly glued (glueing station 45) and hardened (hardener 46). The product thus manufactured is particularly appropriate as a roofing bituminous sheet.

Abstract: The toy with parachute has two arms (26) forming grip, hinged to a head (2) and on which acts a spring (3) to cause the spacing of the arms. At the lower end of each arm there is hinged a large panel (28) on which acts the air pressure and to which are fixed the ties (64) of the parachute. The panels have extensions (29) extending upwardly and engaging, in the closed position of the grip, with a corresponding portion (24a) of the arms The head is carried by a support above the grip. To use the toy, the parachute is arranged inside the grip maintained in a closed position. Then the toy is thrown in the air. The air pressure acting on the panels prevents the opening of the grip or clip by the spring until the highest point of the trajectory is reached. Then the clip opens due to the action of the spring and the parachute opens out by the spacing of the arms and of the panels.

Abstract: The invention relates to percussive drills for earth boring, and particularly to so-called valveless drills. In such drills it is important to allow, cyclically, compressed air to pass into the bore hole to clear debris through a central hole in the bit which central hole needs to be closed to allow the return stroke of the piston. This has been provided for hitherto by a short tube usually of plastics material, secured to the innermost end of the bit so that as the piston approaches the bit on the drive stroke the tube engages in a counterbore in the piston to seal the bore through the bit. Such short tubes are frequently damaged causing cessation of operation of the drill whilst down the hole, a circumstance that is to be avoided. The objective of the invention is to avoid the above disadvantage, which objective is met by a construction comprising an outer wear tube (1), compressed air inlet means (2) to one end of the wear tube, chuck means (3) for holding a drill bit (4) to the opposite end of the wear tube, a cylinder (5) located within the wear tube with an annular gap therebetween, an air diverter (6) located at the end of the cylinder towards the air inlet, a sealing bearing (7) located at the end of the cylinder towards the chuck, and a piston (10) within the cylinder, said piston having a portion (15) of reduced diameter adapted to pass through the sealing bearing to strike a bit held in the chuck, and there being porting (8, 9) to direct air to one side or the other of the piston to provide a drive and a return stroke.

Abstract: The data input/output device of an elevator drive regulation receives actual values of the speed and of the displacement of an elevator cabin at related counters which are connected to related digital tachometers. The data are evaluated and transmitted via an interface to a digital computer of the drive regulation. The digital computer compares the data with stored reference values and computes input values for related adjusting members of the drive regulation. The computed input values are transmitted via the interface to and stored in a programmable multiple counter of the data input/output device. The programmable multiple counter contains three counters each of which is connected through a driver stage with a thyristor associated with one phase of a three-phase a.c.-elevator drive. A synchronizing device ensures that all thyristors are always ignited at any one time at the same phase angle which corresponds to the adjusting magnitude. A further counter of the programmable multiple counter is connected to a driver stage which acts upon the control of an eddy-current brake in the drive regulation.

Abstract: Spring-summer meningoencephalitis (SSME) is caused by the SSME virus. This virus contains a glycoprotein molecule (E) which induces a protective immune response after infection or active immunisation. This entails production of antibodies directed against various antigenic determinants of the glycoprotein molecule, some of which antibodies have a protective action but others being blocking and reducing the protective action. The object is to identify the antigenic determinants with different effects and to provide peptides and peptide-containing compounds which contain one or more of the antigenic determinants which induce protective antibodies or are free of antigenic determinants which induce blocking antibodies. The antigenic determinants are identified by their reactivity with monoclonal antibodies which are specific reagents. The peptides and peptide-containing compounds are prepared by enzymatic or chemical fragmentation of the glycoprotein molecule or by synthetic construction of the appropriate amino-acid sequences. The peptides and peptide-containing compounds can be used to prepare vaccines active against SSME virus infections. Figure 1 depicts the glycoprotein molecule by a wavy line, with the distribution of the various antigenic determinants being illustrated by the binding sites of the corresponding monoclonal antibodies indicated by  ORTHOGONAL  symbols.

The precipitated compound is subsequently separated and is optionally converted into the free base or a pharmaceutically acceptable salt thereof. The yield obtained is substantially higher than the yield obtained by a prior art process employing a tartaric acid derivative as resolving agent.
