Title: Method and device for controlling vehicle brakes
IPC: B60T8/58
Filed: 1966-05-18
Abstract: 1,149,533. Anti-skid braking system. RECHERCHES ETUDES PRODUCTION. 18 May, 1966 [21 May, 1965], No. 22131/66. Heading F2F. The braking members of a vehicle are controlled by the use of at least three signals, viz. a first signal corresponding to the braking desired by the driver, a second signal corresponding to a combination of a fraction of a signal corresponding to the speed of a braked wheel with the value of this latter signal retained in a memory, and a third signal corresponding to the speed of a braked wheel, and a transducer device delivering to the braking members a pressure proportional to the difference between the sum of the first and third signals and the second signal. The transducer comprises (Fig. 25) an upper blade 5 disposed with its ends centralized in airgaps in a permanent magnet circuit 4 by a torsion tube 11 and a lower blade 7 connected to the upper blade by a rod 8 and having one end disposed opposite an orifice 13. Fluid supplied at A passes through filter 15 and orifice 14 and is directed to the orifice 13 and also to the chamber 22 to act on a push rod 19 abutting one end of valve 16. When the upper blade is deflected by the flux in coils B 1 -B 4  the blade 7 is moved, say, towards the orifice 13, the increased pressure in chamber 22 moving the valve 16 rightwards to the position shown to connect the supply A with the outlet p until the pressure at the latter, acting in chamber 23 resets the valve. Movement of blade 7 away from orifice 13 causes the valve to move in the opposite direction to connect the outlet p with the return R. The coils B 1 -B 4  receive signals from the arrangement shown in Fig. 24. Electrical Control System. The pilot's pedal, in the aircraft application described, is connected to a potentiometer PO 1  which energizes, through a load conscious device 102, the coil B 1 . The coil B 3  is connected to produce a positive flux proportional to the speed W 1  of the braked wheel RF as measured by a generator Ge. The current flowing in coil B 2  is proportional to the discharge current of capacitors M, 115, 116, which comprise the memory, the discharge current being the result of the wheel speed decreasing due to slip and of magnitude proportional to the difference between the present output of Ge and the previous value as stored in the memory, and the coil B 2  is connected to produce a negative flux. The algebraic sum of the fluxes in B 2 , B 3  is arranged to be a negative flux corresponding to the wheel slip and proportional to the wheel speed. A coil B 4  provides a negative flux when the wheel speed is low at the end of landing, to prevent an undesired rise in braking pressure which would arise at low speeds, due to noise effects when the signal from Ge is small. Arrangements are described for the use of valves in place of transistors, and the provision of an alternating current generator or other means for measuring the speed of the braked wheel.

Title: Means for re-energising the driving springs of clockwork mechanisms
IPC: G04C1/02
Filed: 1926-09-11
Abstract: 265,093. Geisslinger, J. Sept. 11, 1926. Electric clocks. - Mechanism for re-energizing the driving spring 3 of clockwork comprises a twoarmed balanced lever 1 having weights 12 and also a third arm which coacts with the armature 5 of the magnet 4, the circuit for the latter passing through the point of contact of this third arm and armature 5. This contact is a rubbing one. The third arm carries a pawl 7 driving ratchet 8 and mechanism 9, 10 to the clock, and also has attached to it one .end of the helical spring 3. When the magnet is energized the armature moves to the left until arrested by the magnet core. The three-armed member 1, however, continues to move clockwise owing to the inertia of the weights 12. This stresses the spring 3, causes the pawl 7'to take over another tooth and breaks the magnet circuit. The armature returns to normal and'the member 1 rotates counter-clockwise, driving the clockwofk, until contact with the armature is re-established. The invention is illustrated in a modification in connection with a spiral driving spring.
