Abstract: L'invention concerne l'équipement des pédales de bicyclettes, et notamment de celles à usage sportif.  Chaque pédale 50 est équipée d'un cale-pied 60 qui la déséquilibre lorsque le cycliste dégage son pied, et d'un dispositif 70 qui la ramène et la maintient dans une position angulaire déterminée par rapport à la manivelle.  Ce dispositif comprend une pièce 71 substituée au classique cabochon de fermeture du moyen 53 et un mamelon 72 vissé en bout de l'axe 52 en lieu et place de l'écrou de serrage du palier, portant des bagues respectives 73, 74 magnétiquement polarisées de manière asymétrique mais complémentaire pour la position angulaire voulue.  Des variantes de réalisation sont prévues.  L'invention facilite donc considérablement l'engagement des pieds du cycliste dans les cale-pieds ou équipements équivalents des pédales, en supprimant les inconvénients et risques habituels de cette opération.

Abstract: ABSTRACT OF THE DISCLOSURE     The apparatus is provided with two rolls made of a magnetically conductive material, spaced to define a pas-sage for a sheet being worked.  Either at the first ends, or at both ends of the rolls there are provided means for inducing a magnetic field, so arranged that the magnetic lines extend axially of the rolls and cross the gap there-between, whereby the rolls act as the opposite pole pieces of a single magnetic systems and are designed to retain the ferromagnetic powder which, with the rolls rotating, is pulled through the gap therebetween in a layer used to work the sheet material.  The apparatus incorporates a device for levelling out the distribution of the grains of the ferro-magnetic powder throughout the length of the gap.  The de-vice can be made in the form of a blade positioned to cut off a part of the magnetic powder body at the extremities of the rolls, which enhances the uniform distribution of the grains.  The invention also provides for the rolls having tapering portions at their extremities,  whereby the magnetic flux density at these extremities is reduced and made sub-stantially equal to the density centrally of the rolls.

Abstract: VEHICLE BRAKE CONTROL SYSTEM              ABSTRACT OF THE DISCLOSURE         A vehicle brake control system incorporates a velocity rate change sensitive fluid valve which in-cludes a pendulum member supported in a reservoir of fluid.  The vehicle brake system includes a master cylinder having resilient means to apply pressure to the master cylinder to accomplish braking. To initiate braking, fluid pressure in the control system is reduced and the velocity rate change sensitive fluid valve is arranged to reapply fluid pressure when the braking rate exceeds a predetermined value.  Any loss of fluid pressure in the control system causes vehicle braking to be initiated thereby providing a fail-safe control system.

Abstract: ABSTRACT An adjustable eccentric assembly is mounted on a rotatable shaft and includes a first or drive collar having an arbor extending along the shaft and a second or guide collar mounted at the end of the arbor spaced from the drive collar. The drive collars have respective guide surfaces extend-ing parallel to the axis of rotation of the shaft and a guide tract is formed in the guide collar guide surface extending perpendicularly of the axis of rotation. A hub member is supported between the guide and drive collars and engages the guide track. Adjusting means serve to shift the hub mem-ber radially relative to the rotatable shaft to adjust the eccentricity of its rotation about the shaft. A throw member having a projecting link may be rotatably mounted on the hub member so that the eccentric rotation of the hub member imparts a reciprocating motion to the throw link. Locking means enable the adjustable eccentric assembly to be mounted in any rota-tional relation to the rotatable shaft so as to control the timing of the ec-centric throw.
