Abstract: A single piece gasket valve plate assembly for sealing and separating assembly parts secured to the valve plate (30) of a reciprocating piston compressor (10). The gasket (58) includes a compressible peripheral portion (60) for sealing and separating the valve plate to the cylinder head (28). The device also includes compressible central portions (70), which are spaced from and integral with the peripheral portion, wherein the central portions members are adapted to encircle the suction ports (44) of the valve plate to seal and separate the suction ports from the discharge ports (46). A connecting portion (74, 76) extending through the discharge chamber (34) connects the peripheral portion of the gasket to the central portions.

Abstract: 2.1. Storage holders for recording media such as magnetic tape cassettes, gramophone records, compact discs or the like in which a slide serving as bearing surface for the recording medium is situated in a slidingly displaceable manner are known. 
<??>2.2. A storage holder for recording media is proposed in which, for locking and unlocking the slide in the housing of the storage holder there is provided a locking arrangement in which there is arranged on a button a flexible bending beam which is mounted torsionally flexibly on the slide by means of two bearing stops at least, a bolt located on the said slide disengaging from the opening in the side wall of the housing when pressure is applied to the button, this being caused by deflection of the bending beam, and thus freeing the slide for the ejecting movement into the removal position.

Abstract: Image data is converted into digital data and is read by a scanner (41). The digital data read by the scanner (41) is stored in an optical disk (233). Retrieval data (802, 805) representing the storage position or the like of the data stored in the optical disk (233) is also recorded in the optical disk (233). In addition, paper (P) on which abstract image data of the digital data stored in the optical disk (233) is recorded is output from a printer (43). The respective components of the invention are integrally arranged. This arrangement can simultaneously enjoy both the advantages of a paper file and an electronic file, i.e., quick data access and a large storage capacity. More specifically, a plurality of sheets of document data are replaced with at least one sheet of paper (P) on which simple abstract image data is recorded and image data stored in an optical disk (233), thus allowing easy registration and retrieval of image data of documents and enabling a great reduction in space for documents. In addition, since document retrieval is performed on the basis of paper having abstract data recorded thereon, a high data access speed, which is the advantage of a paper file, can be maintained.

Inventor: GOWLETT DAVID JOHN C O PHILIPS
IPC: H01J7/18
Filed: 1990-05-04
Abstract: A device chamber (12) is evacuated by pumping via an evacuation tube (35) to produce a vacuum space in communication with a chemically-active getter (30) which is provided in the tube (35) to getter gases from the evacuated chamber (12). In accordance with the invention, the getter (30) in the form of one or more movable bodies of the getter material is activated by heating in the evacuation tube (35) at a safe location (36) distant from the chamber (12). It is then moved towards the chamber (12) and is retained in the sealed evacuation-tube outlet (31) of the device. A vacuum-permeable screen (32) in the evacuation-tube outlet (31) inhibits passage of the getter material (30) into the chamber (12) where it might, for example, otherwise damage or obscure an infrared detector element. This permits the inclusion of the getter (30) in an inexpensive manner which does not require the use of a getter unit with a support element and/or vacuum-sealed electrical connections, and is compatible with space limitations and standard device envelope requirements for infrared detectors. Furthermore, the getter (30) is activated by heating at a location which avoids damage to the device, and after moving towards the chamber (12) the evacuation tube (35) is shortened to provide a short (or even non-protruding) outlet (31) from the chamber (12).

IPC: G06F12/00

Abstract: A system and method in which client access to data at a server is synchronised to keep the data consistent by ensuring that each portion of the data accessible for modification at a node is not accessible for reading or modification by any other node, while allowing portions of the data accessible only for reading to be accessible by any number of nodes. If a conflicting request arises from a different client the server must revoke data that has been previously distributed to a client. For a revoke_bytes request, all outstanding get_bytes are marked so that the bytes that are being requested to be revoked will be discarded when they do arrive at the client. To insure that read and write system calls on a file are performed in a serialisable fashion throughout a distributed environment, each machine at which a read is being performed must acquire a read token and each machine at which a write is being performed must acquire a read/write token from the server for the file. When any machine has a read/write token, no machine is allowed to have a read token, although any number of machines may have a read token at the same time. The server coordinates the distribution of these tokens by revoking all read tokens whenever a write token is requested and revoking the write token whenever any read token is requested.

Abstract: A seal ring presses against a wafer on a CVD chuck continuously around the outer periphery of the wafer, and with sufficient force to hold the backside of the wafer against the chuck, so no CVD material may deposit on the backside of the wafer. The seal ring has one surface for contacting the frontside of the wafer and a second surface that extends close to the CVD chuck, so the edge of the wafer is also excluded from CVD coating. With use of the wafer seal ring apparatus and method, CVD coating is confined to the frontside of a wafer. In a preferred embodiment, an apparatus with a slide operated by a cam lever and a tension spring for moving the seal ring and pressing it against a wafer on a CVD chuck is used with each of multiple chucks attached to a rotatable turret within a CVD chamber.

Abstract: An aircraft altimeter has a planar transmit antenna 2 and receive antenna 3 on the same substrate separated by about 150mm. An oscillator 20 supplies microwave energy in the G-band to the transmit antenna via a pulse modulated amplifier 21. The oscillator also supplies an output via a phase shifter 23 to one input of a mixer 24 the other input of which is supplied with the received signals from the receive antenna 3. The phase shifter 23 is controlled to adjust the phase of the signal supplied to the mixer 24 from the oscillator 20 so that it cancels out the leakage signal caused by direct coupling between the transmit and receive antennas 2 and 3.
