Abstract: A phaser valve for a piston and cylinder assembly helps to keep a pair of pistons in phase with each other. The phaser valve includes a poppet which is slidable between opposing seats of a valve housing. The poppet includes a head and a stem, both the head and the stem having concave portions which facilitate the flow of hydraulic fluid across the valve. The poppet head has two generally conical ends, so that the head makes a fluid-tight seal with a seat when the head is urged towards either seat. Due to its construction, the phaser valve may be built to fit within a very small space, while still allowing a substantial flow of fluid when the head is not in abutment with one of the seats.

Abstract: A main stage in-line pressure control cartridge. The cartridge selectively controls flow in-line in the same direction. The cartridge is mounted inside a body and has a sliding control sleeve that can expose radial holes in the poppet to an open position and to seal the radial holes in a closed position. A retainer collar is located on the opposite end of the control sleeve. Flow is permitted in a direction from the control sleeve to the retainer collar. The body has a mating recess to accommodate a step in the retainer collar which prevents movement of the retainer collar towards the control sleeve. When fluid pressure is applied to the retainer collar in the direction of the control sleeve, the step in the retainer collar presses against the body thereby preventing the fluid pressure from moving the retainer collar. Thus, the cartridge only permits fluid flow in the direction from the control sleeve to the retainer collar but prevents fluid flow in the other direction. GLYD RINGS can also be used as seals for the control sleeve and/or the retainer collar.

Abstract: A main stage in-line pressure control cartridge. The cartridge selectively controls flow in-line in the same direction as opposed to directing flow at a 90 degree angle like other cartridges. A tubular poppet can be mounted into a body and has a sliding control sleeve that can expose radial holes in the poppet to an open position and to seal the radial holes in a closed position. The cartridge can be configured in numerous ways in order to serve many functions, such as a pressure relief valve, a counterbalance valve, and a flow control valve. The cartridge can also be configured to allow or prevent reverse flow.

Abstract: A one-piece block connects flanged fluid-flow connectors. Each connector includes a central port and at least two tabs, the tabs having apertures for affixing the connector to the block. The dimensions of the block and the connector are such that the block can accommodate a given number of connectors in a smaller space than required in the prior art. Moreover, the maximum working pressure of the connector can still be as large as about 5000 psi. Channels formed within the block allow fluid communication from one connector to another.

Abstract: A hermetic sealing approach involves welding an Aluminum cover onto a low-cost Aluminum housing. According to an example embodiment of the present invention, a metal housing having a base and sidewalls extending upward therefrom is adapted to receive and couple to an HDD arrangement. The metal housing is formed using material and processing (e.g., cold formed or die cast Aluminum) that are relatively inexpensive. A feedthrough arrangement including a plurality of communication pins extends through an opening in the base and is coupled thereto, with the communication pins adapted to pass signals between the inside and the outside of the metal housing. A metal cover is welded to an upper portion of the sidewalls and, with the feedthrough arrangement, hermetically seals the metal housing.

Abstract: Embodiments of the present invention pertain to a method of manufacturing a disk drive coupling apparatus for rigidly coupling a disk drive to a chassis of a computer. In one embodiment, a disk drive to chassis coupler is formed and a disk drive to chassis coupler engaging mechanism is created. One end of the disk drive to chassis coupler can be coupled to the chassis. The disk drive to chassis coupler engaging mechanism can be used to cause the second end of the disk drive to chassis coupler to apply pressure to the disk drive, thus, the disk drive can be rigidly coupled to the chassis.

Abstract: The invention is a hard-disk-drive (HDD) assembly that includes a flame having the exterior dimensions of a particular form-factor HDD, an HDD with a form-factor smaller than the frame, a pair of mount assemblies that support the HDD entirely within the larger form-factor frame, and an electrical cable located entirely within the frame and having one end connected to the HDD and the other end exposed to the frame exterior at the position determined by the specifications of the larger form-factor. The HDD assembly thus presents a smaller form-factor HDD as a fully plug-compatible alternative to a larger form-factor HDD. The mount assemblies have spring-like cantilever arms in contact with damping material to provide a highly-damped nonlinear spring system that provides mechanical-shock resistance for the HDD in a direction normal to the planes of the disks and high stiffness in a direction parallel to the planes of the disks.
