Abstract: The disclosed motor vehicle hydraulic brake system includes a master cylinder supplying fluid pressure to a front brake circuit and to a rear brake circuit. The rear brake circuit includes a proportioning valve which reduces the pressure supplied to the rear wheel brakes. The rear brake circuit also includes a control circuit. In the event of front and rear braking pressures exceeding predetermined pressure levels, the control circuit modifies the operation of the proportioning valve so that the proportional relationship of the proportioning valve closely approximates a 0.4g deceleration line until the theoretically ideal front to rear pressure relationship for the particular loading condition of the vehicle at the 0.4g deceleration rate is reached. The proportioning valve then closely approximates the theoretically ideal front to rear pressure relationship for the particular loading condition of the vehicle at all higher braking pressures and higher deceleration rates.

The control valve includes a shuttle piston which controls fluid flow between the pump and the brake booster, between the pump and the steering valve, and between the brake booster working chamber and the downstream side of the steering valve. The brake booster includes a trapped volume chamber in which a larger area input rod moves to provide greater movement of an output rod and power piston assembly.

Abstract: A motor vehicle hydraulic brake system includes a front brake circuit and a rear brake circuit. The rear brake circuit includes a blend back proportioning valve which controls the pressure in the rear brake circuit. The blend back proportioning valve includes a proportioning piston which cooperates with a valve seat to maintain increases in rear brake pressure proportional to but less than increases in master cylinder pressure between a first predetermined pressure and a second predetermined pressure. A blend back spool moves the valve seat away from the proportioning piston to equalize master cylinder pressure and rear brake pressure when the second predetermined pressure is reached.

Abstract: A differential pressure sensing switch for a motor vehicle has a piston axially slidable in a housing and exposed at each end to the pressure in separate brake circuits. At one end, the piston has a smaller diameter exposed to fluid pressure than at the other end and a sleeve and seal are slidable on said smaller diameter to have a combined diameter greater than that of the other end. A spring biases the sleeve toward the one end so that on cycling, the piston moves first in one direction and then in the other direction to provide positive movement between each seal and its adjacent sealing surface.

Abstract: A spreader for spreading a fabric having upper and lower sides, transversely spaced edges and longitudinally extending reenforcing cords spaced laterally across said fabric between said edges preparatory to treating the fabric in a calender, as the fabric moves in a given path to the calender. The spreader includes a mandrel having an outer generally cylindrical surface concentric with a rotational axis. The cylindrical surface has a helical groove having convolutions with a pitch generally equal to a desired cord distribution laterally of the fabric. The mandrel is rotatably mounted to a support structure such that the mandrel is positioned transverse to the fabric with the cylindrical surface of the mandrel aligned with the fabric path to be generally tangential to a side of the fabric as the fabric moves in the given path. A first motor positioned on the support structure rotates the mandrel about the axis at a given rotational speed. A second motor moves the support structure in a direction parallel to the rotational axis of the mandrel and at a given linear speed as the first motor is rotating the mandrel until a number of cords of the fabric at the one edge of the fabric are captured in the helical groove and spaced by the pitch of convolutions of the groove at a desired cord distribution. A density detector measures the density of the cords as the cords are captured or prior thereto. The measured cord density is used to adjust the rotation speed of the mandrel and/or the linear speed of the support structure to obtain one cord per groove in the mandrel.
