Abstract: An electrical joint for separating adjacent block circuits of a railway signaling system in which the rails of the railway track serve as conductors. The upstream circuit block carries first frequency signals and the downstream block circuit carries second frequency signals. The electrical block separating joints are bounded by tuning units of which one may be a mere impedance and which are responsive to the frequencies of the circuit blocks and constitute respectively a low impedance for the first or second frequency and a capacitive impedance for the other of the first or second frequency. There are transmitter and receiver units the latter of which is associated to activate a control device, e.g. a relay, for the associated block circuit to de-activate the control device when a vehicle enters the electrical joint by a shunting effect.

Abstract: A process for laying out a maximum number of cigar wrappers in a leaf or half-leaf of tobacco, the position of each wrapper being located within the leaf or half-leaf by two series of variables which are, on the one hand, the abscissa or ordinate from the center of the wrapper plotted with respect to the main direction of the leaf and to one end of this leaf, and on the other hand the angle that the main direction of the wrapper makes with the main direction of the leaf, said process comprising the step of successively laying out the wrappers so that, for each wrapper, the abscissa, or ordinate, from the center or its angle with respect to the main direction is maximum or minimum.

Abstract: A cage for fixing an object by screwing it to a rectangular hole of width a having parallel edges and provided in a metal plate accessible from only one side, comprises a cylindrical socket extended by a collar, the dimension of the socket in a first transverse direction being at most equal to a and two tongues extending from this socket in the transverse direction perpendicular to the preceding one so as to form with the collar two slides adapted to overlap the edges after axial insertion of the cage into the slit, then rotation of this cage by a quarter of a turn in the screwing direction, this rotation bringing into play over-riding of a hard point.

Abstract: Process for distillatively separating a liquid mixture containing at least two miscible volatile components having different boiling points using low-grade heat and, if necessary, low-grade cooling. Distillation is carried out at a pressure sufficiently low to cause the mixture at the bottom of the distillation column to boil below the temperature of the low-grade heat supplied and condensation of at least a portion of the vapor fraction is carried out at a pressure which permits using available cooling liquid. Condensed liquid is returned as reflux to the distillation column at a temperature and pressure essentially equal to the temperature and pressure prevailing near the top of the column. The progressive increase of vapor recompression in the system makes it possible to provide an increasing proportion of the energy to the system in the form of electrical energy, up to the total energy requirement.

Abstract: The invention relates to caseinates of oligo-elements, such as chromium, cobalt, copper, tin, iron, magnesium, manganese, molybdenum, nickel, silicon, vanadium and zinc, containing, for n times 100 grams of casein, from 3 to 100 milli-ion-grams of M.sup.n+, where M represents the oligo-element(s) and n is an integer.The caseinates are prepared from casein by ion exchange in order to introduce the oligo-element(s) therein, followed by washing until a substantially constant composition is obtained. They may also be obtained from alkali metal caseinates.The caseinates of copper or iron may be used as a source of copper or iron with no catalytic activity on oxidation, particularly in infant and dietetic products.

Abstract: A combined device for reaming and collecting dust for use with a drilling apparatus makes it possible to produce a flared mouth for the drilled hole, in particular for subsequently facilitating the insertion of an anchor bolt. The device includes a reamer, through which the drilling bit of the apparatus passes axially, and which is integral with a sleeve through which the bit also axially passes and which is coupled to a hydraulic speed-reducing motor. The inner diameters of the sleeve and of the reamer are greater than the diameter of the bit, in order to provide an annular passage for the evacuation of dust. A container for collecting dust and provided with a guide for the drilling bit is disposed on the side of the driving sleeve opposite the reamer.
