Abstract: A number of embodiments of reinforcing arrangements for vehicle bodies wherein the suspension forces for the ground engaging element are transmitted to the vehicle body and reinforcement is provided in this area. Rather than providing rigid reinforcement, as with the prior art, various forms of damping arrangements are disclosed including those which permit different damping in one direction from the other and utilizing either elastic or hydraulic viscous type dampers.

Abstract: In one embodiment, a suspension system includes a hydraulic assembly. A cylindrical spacer is attached to the hydraulic assembly. An annular seating member is removably coupled to the cylindrical spacer and supports a biasing member. In another embodiment, the annular seating member is coupled to the hydraulic assembly. A support member is removably coupled to the cylindrical assembly.

Abstract: A damper comprises a first chamber and a second chamber separated by a piston. At least one of the chambers includes an axially moveable member and an axially fixed member. A resilient or compressible member is positioned between the axially moveable member and the axially fixed member. The axially moveable member is displaced toward the fixed member during slight pressure increases to absorb small pressure fluctuations that may be insufficient to cause flow through the piston.

Abstract: A vehicle suspension system including a first and second hydraulic damper is provided. Each hydraulic damper is provided with a cylinder and a piston connected to one end of a hollow piston rod, such that the pistons freely slide in the cylinder. The system also includes a pressure regulator, which has a first and second oil chamber connected to the first and second hydraulic dampers, respectively. The system additionally comprises a sub-piston and another piston connected to the sub-piston, which slidably engage in the hollow piston rod, forming an oil chamber.

Abstract: A hydraulic piston assembly includes a cylinder assembly having an inner bore that defines an internal space. A piston is disposed in the space and divides the space into first and second fluid chambers. The piston comprises a side annular surface, a first surface adjacent the first fluid chamber and a second surface adjacent the second fluid chamber. The side annular surface comprising a first portion, a second portion and an annular groove between the first and second portions. The first portion has a maximum diameter that is less than the maximum diameter of the second portion. A sealing member is positioned within the annular groove. In some embodiments, the cylinder assembly forms part of a dampening system that interrelates at least two suspension assemblies. Methods for assembling the hydraulic piston assembly are also disclosed.

Abstract: Process for producing a hydrochloride of a vancomycin antibiotic, comprising subjecting an aqueous solution of a hydrochloride of a vancomycin antibiotic to a primary freezing at from −1° C. to −20° C. for a time sufficient to grow ice crystals, to form a primarily frozen substance, then subjecting said primarily frozen substance to a secondary freezing at from −25° C. to −80° C. to form a completely frozen solid, and then drying the resulting frozen solid in vacuo; and product obtained by the process.

Abstract: A number of embodiments of piston sealing arrangements for shock absorbers having a hydraulic cylinder in which a piston is slidably supported to define a pair of fluid chambers. The piston is provided with a peripheral groove in which a sealing piston ring is provided. A number of different communicating passage arrangements are formed in the piston ring that communicate the exterior surface of the piston ring which engages the cylinder bore with the interior surface of the piston ring which faces the ring groove so as to balance the pressure therebetween. In each embodiment a seal is provided between the piston ring groove and the piston ring so as to preclude fluid flow from one fluid chamber to the other through the piston ring groove and the communicating passage arrangement.

Abstract: A number of embodiments of induction systems for internal combustion engines that permit operation on the Miller cycle without introducing pumping losses or by substantially minimizing the pumping losses. Basically, the system provides a variable volume air chamber that supplies the major portion of the intake charge or all of the intake charge under low-speed, low-load conditions. Various valving and variable volume chamber constructions are illustrated. In addition, embodiments using air-assisted fuel injection are also disclosed.

Abstract: This invention relates to an encapsulated pharmaceutical dosage form comprising a practically insoluble compound or salt and an intracapsular fluid, and/or a surfactant and/or cellulose derivative. It provides for increased oral absorption as compared with the conventional system because, on release of capsule contents from the capsule shell, the practically insoluble compound or salt undergoes diminution in crystal size.

Abstract: A variable damping force hydraulic shock absorber has a solenoid driven control valve that controls the size of an opening to a control passage contained within the piston rod. The control passage allows fluid contained within the cylinder to bypass the resistance mechanism of the piston. The size of the opening to the control passage varies according to the movement of a control element within the hollow piston rod. The movement of the control element is controlled by the magnitude of the electrical current delivered to a solenoid driven control valve. The movement of the control element is aided by a compression spring located between the control element and an adjusting bolt. The damping force of the shock absorber is externally adjustable by turning the adjusting bolt located within one end of the piston rod.

Abstract: A number of embodiments of suspensions for steered wheels of a vehicle embodying upper and lower suspension arms with the upper arm connected to the vehicle by a ball joint so that the steering of the wheel is accommodated by pivotal movement of the upper arm. This arrangement reduces tread changes during suspension and steering movement. A wide variety of locations and orientations of the upper and lower arms and loading for the suspension units are disclosed.
