    • The present invention discloses a waterproof relief outlet in a chest wader. A waterproof folded funnel having a pair of inner flanges at one end is secured through a center seam of the chest wader. A funnel housing having an inner flap and an outer flap is attached to a back side of the center seam of the chest wader in conjunction with the inner flanges of the funnel. An interlocking tongue is also provided with the inner and outer flaps of the funnel housing. A wearer of the chest wader can relieve his pressure by unlocking the interlocking tongue and unfolding the inner and outer flaps of the housing through which the folded funnel is extended and unfolded.

    • The circuit configuration for a brake system having an anti-locking control generates pulse-type brake pressure control signals. For pressure rebuild-up after a pressure decrease, brake pressure is applied first at a steep and subsequently at a flatter gradient, this being achieved by a variable pulse (P1) and by short fixed pulses (P2) succeeding one another at a large interval. Circuits are provided rendering dependent the pulse and pulse break times (T.sub.1, T.sub.2, T.sub.k) determining the pressure build-upon the duration of the pressure build-up (T.sub.1) during the steep-rise build-up in the preceding cycle,on the duration (T.sub.1 +nT.sub.2) of the entire pressure build-up in the preceding cycle, andon the duration (T.sub.o) of the preceding pressure decrease, with the pulse times being so dimensionedthat, at a constant coefficient of friction and at a constant static pressure, the locking limit of the wheel is rereached after a predetermined period of time or after a predetermined pulse number. The duration of the variable and of the fixed pressure build-up pulses is computed from the pressure build-up of the preceding pressure or determined from a stored Table.
