Abstract: The present invention concerns nutritionally complete food compositions which contain partially hydrolyzed pectin. The partially hydrolyzed pectin has a peak molecular weight less than unmodified pectin and greater than 3,300.
Abstract: A brake booster which is capable of appropriately varying the amplifying ratio thereof according to information on a brake pedalling force obtained as an input of a brake system and information on deceleration of the vehicle obtained as an output of the brake system.

Abstract: A brake booster for a vehicle comprises first and second control pistons operated by hydraulic pressure from a master cylinder, and a power piston pneumatically actuated in response to movement of the control pistons to increase braking pressure applied to the wheel brake cylinders of the vehicle. To control the increasing ratio of the braking pressure in accordance with the changes of the vehicle weight, under unloaded condition of the vehicle only the first control piston is operated by the master cylinder pressure to actuate the power piston and under loaded condition of the vehicle the second control piston co-operates with the first control piston by the master cylinder pressure to accelerate the actuation of the power piston.
Abstract: The vacuum chamber of the master booster is connected to a slave booster having a chamber also normally below atmospheric pressure. The variable pressure chamber of the master booster is connected to the other chamber of the slave booster through a check valve. The master booster operates a dual master cylinder with one pressurizing chamber connected to the rear brakes and the other pressurizing chamber connected to the master cylinder associated with the slave booster and then to the front brakes. In the first stage of actuation the master booster operates its master cylinder to pressurize the front and rear brakes equally. When a preselected boost level is reached, the pressure increase in the master booster variable pressure chamber will open the check valve and the pressure increase will be delivered to the slave booster.
Abstract: A throttle actuator for accelerating and decelerating the speed of an internal combustion engine in response to work demand where the engine drives the pump of a hydraulic system. In one aspect, the invention is directed to a throttle actuating piston and rod arrangement for operating the throttle of the engine and a pulsation intensifier for sensitively controlling the piston's movement. The pulsation intensifier is connected in a pressure line from the pump and comprises a free spring biased floating piston of configuration such that there is a differential in area across the piston for fluid pressure intensification purposes. The intensifier piston in one embodiment also has an axial passage therethrough and an orifice communicating with the throttle actuating piston. Both pistons are slidably mounted in housings which have springs to normally position the pistons in directions to cause the engine to return to idle speed when there is no work demand.
