Abstract: This relates to a hydraulic brake system particularly adapted for use in conjunction with large rotating masses. The system includes at least two calipers which are widely spaced. In accordance with the system, there is positioned adjacent each caliper a solenoid valve and there is at each valve a constant supply of hydraulic fluid under pressure so that when the valve is actuated there is an immediate supplying of hydraulic fluid under pressure to each caliper. The arrangement permits an early response time as compared to systems wherein the system must be pressurized from a remote source.

Abstract: This relates to a blow molding apparatus of the rotary wheel type and particularly relates to supplying fluids, such as air, vacuum and water to a mold half and its associated carrier in a manner which permits the reciprocation of the mold half and associated carrier between a mold open position and a mold closed position. This is facilitated by the use of short lengths of hose which are attached to respective manifolds by swivels. The swivels permit the ends of the hose to change their angular relationship as one end of each hose moves relative to an opposite end of the hose. Adjacent ones of the hoses are located in adjacent parallel planes and are initially bowed in one direction and reverse their direction of bow as movable ends of the hoses move beyond fixed ends of the hoses. The carrier for the movable mold half has associated therewith a cam follower for engaging a cam which effects the opening and closing of the mold.
