Abstract: 1482449 Frictional detents; band brakes T SESSA 17 Oct 1974 [9 Nov 1973] 45128/74 Heading F2E [Also in Division E2] A driving shaft 10 of a vehicle window is braked in its directions of rotation F, F1 corresponding to raising and lowering of the mobile upper part of the window by a spring 12 comprising two parts 13, 14 interconnected by a bridge 15; the coils of portion 13 are adapted to rest under preload against the shaft 10 to apply a braking action thereto while the coils of portion 14 are loose on the shaft 10, the ends 16, 17 of the respective spring portions 13, 14 and the bridge 15 being co-operable with abutment forming shoulders 18, 19 on a housing 11 of the shaft 10 to control the action of the spring 12. When the shaft 10 is rotated in a clockwise direction F, corresponding to upward movement of the upper mobile window part the bridge 15 engages against the shoulder 19, to concel the torque which spring portion 14 applies to portion 13 so that shaft 10 can freely rotate. When the shaft 10 is rotated in the anticlockwise direction F1, the spring portion 13 remains locked on shaft 10 and rotates therewith until its end 16 engages shoulder 18 to thereafter cause the spring portion 13 to loosen and portion 14 to partially tighten around shaft 10 to brake the descent of the window part. When the shaft 10 ceases rotation the system returns to the equilibrium position indicated in Fig. 3 (not shown). Figs. 5-8 illustrate a practical application wherein shaft 10 which is rotated by pinions 23 is of square cross-section and the spring 12 is mounted on a sleeve 32 of square inner crosssection and circular outer cross-section mounted on the shaft 10. A normal torsion spring 28 designed to balance the weight of the mobile part of the window is also provided.

Abstract: A function generator (25) receives the signal (svm) representing the speed of rotation of a motor (13) and works out EN=CN+f (vm), f (vm) being a single-valued and monotonic function of the real speed vm of the motor and CN being worked out by computer means (24) so that: CN=EN-f (VM), VM being the nominal value of the speed of rotation of the motor. The latter is fed by a signal which is a function of EN. The reference information f (VM)=IC is worked out from an item of error information which is a function of the deviation between the real speed (vb) and reference speed (vp) of a tape (10) driven by the motor, the rate of variation of IC having a maximum value limited in absolute value. The device is suitable for subordinating the rate of travel of a tape carrying sound to the frequency of a pilot signal.

Abstract: A system for providing information to alter the software of an electronic data processor embedded in an electronic module includes a remote reprogramming module that conducts a sequence of operations to provide data to the processor which the processor uses to reprogram itself. The system employs a data link having a bi-directional transmission path connecting the processor and the reprogramming module. A controlled switching circuit is provided at each end of the transmission path. Under normal operating conditions, the transmission path is used to transit a function signal for a function performed by the electronic module. Periodically, the processor operates one switching network to capture the path for transmission of a reprogramming inquiry signal to the reprogramming module. At the same time, the function signal is diverted to an alternate path internal to the electronic module. When the reprogramming module detects a reprogramming inquiry, it operates the other switching circuit to gain access to the transmission path. Then, in response to commands from the processor, the reprogramming module undertakes the reprogramming sequence and transfers data to alter program information held in the memory of the processor. Thereafter, both the processor and the reprogramming module operate their respective switching circuits to restore the transmission path to its normal operational use for the transmission of the function signal.
