Title: Free electron laser
Inventor: VILLA FRANCESCO
IPC: H01S3/30
Filed: 1990-12-28
Abstract: A high gain, single-pass free electron laser (10) formed of a high brilliance electron injector source (20), a linear accelerator (30) which imparts high energy to the electron beam, and an undulator (40) capable of extremely high magnetic fields, yet with a very short period. The electron injector source (20) is the first stage (gap) of the linear accelerator (30) or a radial line transformer driven by a fast circular switch. The linear accelerator (30) is formed of a plurality of accelerating gaps arranged in series. These gaps are energized in sequence by releasing a single pulse of energy which propagates simultaneously along a plurality of transmission lines, each of which feeds the gaps. The transmission lines are graduated in length so that pulse power is present at each gap as the accelerated electrons pass therethrough. The transmission lines for each gap are open circuited at their ends. The undulator (40) has a structure similar to the accelerator (30), except that the transmission lines for each gap are substantially short circuited at their ends, thus converting the electric field into magnetic field. A small amount of resistance is retained in order to generate a small electric field for replenishing the electron bunch with the energy lost as it traverses through the undulator structure (40).

Abstract: BILLING SYSTEM FOR TELEPHONE      SIGNALING NETWORK Abstract of the Invention A billing system for use in a telephone signaling network. The network comprises offices through which telephone calls can be routed, each office beingowned by a telephone company that participates in the network. Each office includes a signaling point (SP) that includes means for formulating message signaling units (MSUs). An MSU may comprise a query requesting call data pertinent to a particular call, for example, for verifying the validity of a credit card number. The network also includes signal transfer points (STPs) for receiving and routing the MSUs, and a plurality of service control points (SCPs), each SCPbeing linked to one of the STPs. Each SCP comprises a database that includes call data provided by one or more of the participating telephone companies. The billing system of the invention includes means for capturing at least a portion of the MSUs received by one or more STPs. The billing system processes the MSUs to produce usage data that indicates service recipients and service providers. The service recipient is the telephone company that owns the SP that formulated the MSU, and the service provider is the telephone company that provided the call data for the MSU, or that transported the MSU. The usage data may then be used to produce invoice data for accurately assigning costs among the telephone companies.
Patent CA-2033983-A1 (CA)
IPC: H04K3/00
Filed: 1990-05-14
Abstract: A system and method are disclosed for pre-venting intelligible interception of information sig-nals transmitted over a two-direction line.  A masking signal is applied through a hybrid circuit at the receiving end of the line, and this masking signal, which appears on the line together with the informa-tion signal, prevents intelligible decoding.  The masking signal includes a series of frequencies which are sequentially applied.  Only at the receiving end of the line, where the hybrid circuit attenuates the masking signal which it receives at its receive port, can intelligible decoding take place.  The amplitude of the information signals is sensed at the receiving end and the amplitude of the masking signals on the line is adjusted to be great enough to provide security, by confusing an eavesdropping detector, yet small enough at the receiving end so that the receiv-ing detector is not confused.

Title: Control valve vibration damper/isolator
Inventor: ROSS JOSEPH W
IPC: F01D17/14
Filed: 1991-01-31
Abstract: PATENT 55,477 ABSTRACT OF THE DISCLOSURE          A damper/isolator  device  having  four  ring segments (38) which are retained in slots (36) in an upper guide  (31).   The four segments (38)  are forced radially outward against a valve bonnet liner (30) and are retained and centered within the slot (36) by serpentine or buggy type springs (44). The natural frequency of the damper and spring system is designed to be significantly higher than the frequency of the applied vibration induced by steam flow across a valve seat.  This provides for the isolation of the valve plug (13) from the liner (30) and bonnet bore (11).   The surface interaction between the ring segments (38) and the upper guide (31) provides for added friction damping to the system.

Title: Process for separating mixed fatty acids from deodorizer distillate using urea
Inventor: MAZA AURELIA
IPC: C11C1/08
Filed: 1991-04-24
Abstract: ABSTRACT    A process is described for separating deodorizer distillates, which are byproducts from processing vegetable and animal fats and oils, into a light fraction enriched in fatty acids and a heavy fraction enriched in tocopherols and sterols.  Melted deodorizer distillate is added to a heated solution of urea dissolved in alcohol.  The solution is preferably non-aqueous but may contain small quantities of water as an impurity.  A crystalline complex of urea and fatty acid is formed which is removed from the solution and dried.  The remaining mother liquor is saved for subsequent processing. The dried crystals are dissolved in water to yield an organic layer of fatty acids and an aqueous layer of urea.  An organic fraction rich in tocopherols and sterols is separated in the same manner from the mother liquor, which was saved previously, by evaporating the alcohol to form a residue, mixing the residue with water and separating the organic layer.     cpc9002c

Abstract: Abstract Bonding of Thermoset Composite Structures A pair of thermoset composite structures (19,19') are bonded together by a pair of adhesive strips (10,10').  An adhesive strip (10) is comprised of a layer of semi-crystalline thermoplastic material (12), a layer of amorphous thermoplastic material (14), a layer of dry fiber reinforcement  (16) partially embedded in the layer of amorphous thermoplastic material (14), and a layer of thermosetting resin (18) covering the exposed fibers of the dry fiber reinforcement.  An adhesive strip is bonded to the bonding surface (20) of the structure (19) during the curing process for the thermoset composite structure. A resistance heating element is placed between the bonding surfaces (20,20'), the bonding surfaces (20,20') are pressed together, and electrical energy is passed through the heating element (24) to heat the joint and fuse the thermoplastic adhesive layers together.  The dry fiber reinforcement (16) forms a mechanical lock between the cumulative layer of thermoplastic adhesive (32) and the thermosetting structures (19,19') to provide the bond strength.
