    摘要: A hydrostatic drive system has a motor-driven hydraulic pump (1) connected to at least one hydraulic drive unit (7) by a first working line (19) and a second working line (21) forming a hydraulic circuit. The drive unit is connected to a gear set (1, 3). A first hydraulic accumulator (53) for accumulating pressure energy can be connected to one of the working lines (19, 21). A second hydraulic accumulator (55) can be connected to the other working line (19, 21). A valve device (V1, V2) permits the segment (23, 25) of each working line (19 or 21) extending to the drive unit (7) to be separated to separate an accumulator part (33) from the part of the circuit with the hydraulic pump (13). The accumulator part includes the hydraulic accumulators (53, 55) and at least one drive unit.

    摘要: Compositions of matter, sheet material, and packages made therefrom. Novel compositions of polypropylene and high density polyethylene are useful as sealant materials for flexible sheet material structures wherein the sheet material is sealable to a preformed container, to form a lid therefor, and is peelable therefrom, with cohesive failure of the sealant layer in the area of the formed seal. The novel sealant layer compositions provided for package closure and sealing which is capable of withstanding retort conditions while maintaining the integrity of the package closure and seal. Concurrently the lid is readily peeled from the package to provide access to the interior of the package. The peelability comprises cohesive failure of the sealant material in a novel blend of a polypropylene polymer with an ethylene polymer having a density of at least 0.940. The novel sealant materials of the invention can be used on a variety of multiple layer sheet material substructures, and particularly those providing barrier properties to food type packaging: especially barrier to the transmission of oxygen and moisture. Typical barrier materials are metal foil, vinylidene chloride copolymer, vinyl alcohol copolymer, olefin polymers and copolymers, and combinations of the above materials.

    摘要: A hydrostatic hybrid drive system for road vehicles includes a pump/motor unit (1) connected to the powertrain of the vehicle, controlled by a control unit (5) in a pump or motor operation, and connected to a high-pressure hydraulic accumulator via a first working line (7). The first working line can be closed by a control valve (45) and connected to a low-pressure hydraulic accumulator via a second working line (9). The high-pressure hydraulic accumulator and low-pressure hydraulic accumulator are formed by a double-piston accumulator (11), in which a high-pressure side and a low-pressure side having respective accumulator pistons (15, 17) are formed in an accumulator housing (13). The fluid chambers (23, 25) of the high-pressure side and the low-pressure side are separated by a central housing part (21) through which the common piston rod for both accumulator pistons (15, 17) extends. The control unit (5) of the pump/motor unit (1) having a control area can be supplied from the first working line (7) via a line connection (59) provided on the first working line (7) between the pump/motor unit (1) and the control valve (45).
