Abstract: Drive apparatus for operating a railway level crossing barrier which is implemented in order to lower the barrier in the event of a power failure, even if the actuating apparatus is of the self-locking type, in which the apparatus includes an actuator element 16 rotated to and fro by means of an actuator motor 3. According to the invention, the actuator apparatus has a shaft 1 which causes the barrier to oscillate, the shaft being capable of rotating with respect to the actuator element 16, which is pushed with respect to the shaft with the aid of a spring 35 in order to lower the barrier. Engagement means 18-20, in the applied position thereof, connect the shaft and the actuator element together in order to rotate, and they are under the influence of electrically controlled operating means 2231 so that application can be discontinued in the event of current failure, as a result of which the spring enters the stationary actuator element and the shaft provides a torque for lowering the barrier. (Figure 1).

Abstract: Method and installation for producing a diode holder. The method consists in, in a blank (for signs or the like), forming bowl-shaped reflectors and making openings for mounting diodes 1. Diodes are then mounted in these openings, which diodes are wedged securely in the opening by virtue of their being designed with a broader rear part. The installation comprises a machine frame 14, on which a slide consisting of two pairs of parallel bars 16 is horizontally movable. On this slide, stamping and punching members 19 are vertically movable. These members comprise a pair of blocks which can be moved in a synchronized manner each on its own side of the blank 13 and are designed with tools for forming the reflectors and making the openings in the blank 13. <IMAGE>

Abstract: The seal comprises two plates (1,2) fixed parallel to one another on the shaft. One of the plates (2) has a smaller dia. than the other, and has a number of holes (4)(3). Each hole has bent vanes directed alternately towards the tangential movement of the plate, so that air can flow between the plates through the holes independently of the direction of rotation of the shaft and plates. Air eliminated the circular holes acts as acurtain. A conical body surrounds the seal with which it has direct contact when stationary. There is no direct contact between them during drive for the reason that air flows between the plates.

Abstract: Method of monitoring and/or diagnosing the operational state of a complicated, dynamic system constituted by a machine or an industrial process installation, a plurality (M) of state variables being measured at a plurality (N) of instants for the assembly of a corresponding measurement data (Xik), which are processed statistically to form at least one reference class corresponding to a specific operational state. There is used here a group of measurement data (Xik) serving as a learning group, which is adapted by linear projection to a new coordinate system with fewer coordinate axes. In a corresponding way, current measurement or calculation data are adapted to the new coordinate system, whereupon the distance between the current measurement or calculation data, on the one hand, and the measurement data corresponding to the learning group, on the other hand, is determined. If this distance exceeds a predetermined value, it is established which state variables that cause the deviation, by calculating the effect of the respective state variable on the variance along the respective coordinate axis in the new coordinate system.

Abstract: A method of quantizing the line spectral frequencies (LSF) when calculating the parameters of an analysis filter is included in a linear predictive coding (LPC) speech coder. The line spectral frequencies form an alternative to the filter parameters with unambiguous correspondence. Sum polynomials (P) and difference polynomials (Q) are constructed from the direct form coefficients of filters. Thereafter, the roots of the polynomials which correspond to the line spectral frequencies are determined, without calculation, by examining the polynomials in light of pre-selected test frequencies (ftp1, ftqf1, ftp2, ftq2, . . . ) that are speech typical. The polarity of the two polynomials (P, Q) is investigated for each of these test frequencies. When a polarity change occurs between two test frequencies, one of these frequencies, such as the higher frequency, is chosen. The chosen frequency gives a given root (p1 and q1 respectively) of the respective sum and difference polynomial (P and Q), and therewith a line spectral frequency (LSF1 and LSF2 respectively).

Abstract: The present invention relates to a safety lock for a transport vehicle, intended to prevent unauthorized moving or unloading of the vehicle. The safety lock can be constantly in operation regardless of whether the vehicle is manned or unmanned. A safety lock device according to the invention has a number of functions and actuates at least one system which determines the possibility of moving the vehicle and at least one system which determines the possibility of gaining access to the loading compartment of the vehicle. The safety lock can be opened only with knowledge of one or more codes and can work firstly by preventing the parking brake of the vehicle from being released and secondly by preventing a so-called tailgate lift fitted to the vehicle from being moved from a position in which it wholly or partially covers the opening to the loading compartment. The invention is expected especially to find application in connection with the transport of valuable objects. <IMAGE>
