Title: High pressure fluid regulator
Inventor: WHITE LAWRENCE W
IPC: G05D16/06
Filed: 1991-11-27
Granted: 1994-05-24
Abstract: ABSTRACT OF THE DISCLOSURE    A fluid pressure regulator provides features which enable an extended regulator life in high pressure service.  Dual flexible diaphragms provide chemical resistance in contact with the working fluid and abrasion and fatigue resistance in contact with a backup plate and piston assembly.  The backup plate has a bore which is sufficiently long and close fitting with the piston so that axial alignment is assured and there is minimal tendency for the piston to become cocked within the bore.  Provision is also made for preventing fretting corrosion between the piston and the backup plate by coating at least one of the surfaces, if necessary, to assure that dissimilar metals only are in contact in that couple.  Seals between the regulator housing body and the diaphragm and between the valve stem and diaphragm may be provided by resilient seal rings or by annular protrusions integrally formed on one or both of the diaphragms.

Granted: 2003-01-21
Abstract: A superalloy article is fabricated by casting a high melting temperature superalloy composition and then refurbishing the primary defects that are found in the surface of the cast piece. The article is refurbished by excising the primary defects and a surrounding portion of metal by grinding. filling the excised volume with metal of the same composition as the cast article by welding or a similar technique. smoothing the surface around any resulting filler metal defects, and applying a cladding powder to the surface from which the filler metal defects are removed. The cladding powder is applied by painting a binder onto the surface and then dusting cladding powder onto the binder before it has dried. The cladding powder is a mixture of particles of a high melting temperature superalloy and particles of a lower melting temperature metal. The article is heated to a preselected temperature, depending on the alloy, to melt and subsequently solidify the cladding powder. Finally, the article is hot isostatically pressed to achieve final closure of surface defects.

Granted: 1999-04-13
Abstract: This invention relates to a communication network intended for secure transmission of speech and data, including different types of subscriber terminals (1-4) and switching modules (7-8), where subscriber lines (23-26) connect each subscriber terminal with a switching module and transmission links (19-22) connect each switching module to other switching modules in the network, where transmission links and subscriber lines each carry one or more communication channels, and where the network further comprise crypto devices (13-15) to undertake encryption/decryption or other required protection mechanisms of information transmitted through the network, and where at least one of the crypto devices is constituted by a crypto-pool device having a number of crypto modules (35) which is physically separated from the switching modules (7,8), and which may communicate with the switching modules through standardized interface and communication protocols which makes the device accessible from subscriber terminals, from switching modules or from other network equipment. At least one of the crypto pool devices is a security guard (9 or 10) arranged at the interface between a switching module (7 or 8) and one of its transmission links (19 or 22) such that no impact on the switching module is required. The security guard (9 or 10) includes means stored and managed by a managing device (30) for specifying the criteria for whether a communication channel should be subjected to encryption-/decryption or a data packet (message) on a virtual communication channel should be subjected to protection as required. The security guard (9 or 10) includes means stored and managed by the managing device (30) which during installation or a managing procedure are configured by a security manager (17) for monitoring control information on the signalling channel (38 or 39) to detect whether a particular communication channel is to be encrypted/decrypted or a data packet (message) is to be protected as required.

Title: Rotary valve with single or double channel spool
Inventor: SINDERMANN MARTIN
IPC: F16K11/087
Filed: 1992-05-06
Granted: 1994-09-13
Abstract: A rotary valve has cylindrical flanges and a spool which includes at least one straight cylindrical flow channel.  A geometrical butt-joint is avoided in both rotary positions of the spool thereby obviating reworking of the housing and/or spool.  The cross-section of the flow path is kept constant when the circumferential surface of the spool and the housing inner surface are constructed as parallel freeform surfaces having such a curvature that the mouths of the flow channel and the mouths of the flanges in the inner surface of the housing are non-overlapping (congruent) sectional planes in both rotary positions of the spool.  The valve is more economically manufactured, since reworking of the housing and spool is obviated and the spool can be made as a one-piece casting.

Abstract: A multi-functional cover member is provided for wall joint systems.   Architectural structures frequently are constructed to provide a plurality of independent structur-al units to accommodate relative motion resulting from thermal expansion and contraction, for example, or possibly from seismic activity.  The space between units is covered by a plate, mounted to allow for movement.  An improved and economical  form of multi-functional  cover plate  is  an elongated member of uniform cross section throughout, which includes  spaced-apart  contact  means  for  engaging  the adjacent structural units.  The cover member is specially configured so that a single design of cover can selectively accommodate a wide variety of mounting arrangements.  These include an anchoring base,  for receiving screws or the like, a continuous, downwardly opening slot on the bottom of the cover to selectively receive mounting clips previ-ously fastened to one of the structural units, and opposed laterally opening slots on the bottom of the cover for the selective reception of a centering clip mounting device. The cover member also has semi-cylindrically edge margins for the selective reception and retention of a decorative plastic shell.   The multi-functional  design enables  a single part to be utilized in a wide variety of ways, heretofore requiring a plurality of individually manufac-tured parts.  Significant savings in inventory and handling costs are realized by both the manufacturer and the in-stalling contractor.
Patent CA-2097380-C (CA)
Inventor: GRIME THOMAS E
IPC: B05B9/01
Filed: 1993-05-31
Granted: 1999-04-27
Abstract: A paint spray gun having a dual operating mode trigger. The trigger pivots on a gun body about an axis. The two operating modes are selected by radially positioning the trigger relative to the axis. In a first operating mode, fluid flow to a nozzle is gradually increased as the trigger is gradually squeezed to permit fluid flow control for feathering the applied coating. In this mode, the trigger is mechanically linked for actuating a valve needle. In asecond operating mode, a small actuating movement of the trigger operates a valve which causes a piston to move the valve needle to its fully open position. The second operating mode provides only on-off fluid control with a very short trigger stoke and a low trigger force.

Title: A clock recovery circuit for serial digital video
Inventor: FRANCIS JOHN R
IPC: H04N7/24
Filed: 1993-12-23
Granted: 2004-06-01
Abstract: A control circuit for use with a phase locked loop in a digital video receiver. The digital receiver accepts a serial digital input signal which can comprise composite or component video signals. The phase locked loop comprises a phase detector, a loop filter, and a voltage controlled oscillator (VCO) and includes a divide-by-two modulus divider coupled to the output of the VCO. The VCO has an oscillation frequency control port and the divider has a frequency select port. The control circuit includes an automatic fine tuning and frequency sweeping stage which is coupled to the output of the loop filter and the oscillation frequency control port. The tuning and frequency stage provides temperature drift correction for the VCO. In addition, the tuning and frequency stage "sweeps" the oscillation frequency of the VCO to aid in "locking" the phase locked loop to the phase or frequency of the input signal. Once locked, timing signals and digital data can be extracted from the input signal. The control circuit also includes a video signal detector stage for detecting whether the input signal comprises a composite video signal or a component video signal. The video signal detector stage produces an output signal which controls the modulus of the divider in the phase locked loop.
