    摘要： A shunt device for shunting cerebrospinal fluid (CSF) from a CSF containing space to a sinus system cavity comprises a tubular inlet element, a flow restricting part, and a tubular outlet element having an outlet end with an outlet opening for insertion in the sinus system cavity, and a one-way valve preventing flow in a direction from the outlet opening to the inlet opening. The shunt device further comprises a distancer, said distancer being provided at the outlet end of the tubular outlet element.

    摘要： A shunt device for shunting cerebrospinal fluid (CSF) from a CSF containing space to a sinus system cavity (21) comprises a tubular inlet element, a flow restricting part, and a tubular outlet element having an outlet end (17) with an outlet opening (19) for insertion in the sinus system cavity (21), and a one-way valve preventing flow in a direction from the outlet opening to the inlet opening. The shunt device further comprises a distancer (35), said distancer being provided at the outlet end (17) of the tubular outlet element.

    摘要： In cathode-ray tubes utilising screens with a luminescent layer made up of two kinds of phosphors having different spectra, one having virtually no remanence (1), and the other being of remanent kind (2), with switching of the voltage between two values, low and high, the second phosphor only being excited at the high value, due to the presence of a barrier B, in order to prevent the unwanted flash of different colour, produced by the non-remanent phosphor at the instant of appearance of the remanent trace, the invention provides for the addition to the aforementioned two constituents, of a third non-remanent phosphor (3) equipped with a barrier B and having a spectrum such that the superimposition of the flash which it yields at high voltage, and that yielded by the phosphor (1), produces the colour corresponding to the phosphor (2). Application to radars using real and synthetic video signals.

    摘要： The present invention relates to a radar system haing a high range resolution. Said radar system emits series of n pulses whose carrier frequencies are distributed within a band B and whose time positions are associated with the frequency in accordance with a linear reelationship. The echoes received in return are demodulated with the corresponding waves which gave rise to them, and supplied to a filter bank which produces at different outputs, different signals which correspond to separate objects or parts of objects.

    摘要： A processing device for stretching video signals in a pulse radar system between the output of the receiver of large pass bandwidth and exploiting means such as an oscilloscope. A delay line connected to the output of the receiver provides a plurality of output signals to an non-linear circuit which transmits, to said exploiting means, only the signal having the greatest amplitude and blocks the other signal for preserving the signal to noise ratio.

    摘要： A high-precision digital-to-analog converter, manufactured by the technique of monolithic integrated circuits, uses integrated resistors formed by ion implantation. The resistors are arranged in a series of ladder networks, the steps of each ladder corresponding to predetermined binary digits of a logical information. Fuses interconnect different steps of different ladders; they can be melted by passing an overload current through them. Their elimination in suitable locations facilitates an adjustment of the converter.
