Title: Double containment pipe joint assembly
Inventor: ZIU CHRISTOPHER G
IPC: F16L39/00
Filed: 1992-04-03
Abstract: A double containment pipe joint assembly is provided with an inner pipe and an outer or containment pipe secured in concentric relation. The pipe joint assembly includes a fitting (20) having end surfaces on concentric flanges (22, 36) which can be secured to a length of a primary and containment pipe at intervals along the pipeline wherein sections of the pipeline can be removed and repaired without the necessity of removing the whole pipeline.

Title: Frequency synthesizer
Inventor: FERNANDEZ DURAN ALFONSO
IPC: H03L7/191
Filed: 1993-10-20
Abstract: SUMMARY            Frequency synthesizer Based  on  a phase lock loop structure, composed  by  a  reference signal generator  (1), a first phase detector (2), a low  pass  filter (3), a VCO (4) and a frequency divider (5).     In  order to achieve a faster channel switching,  maintaining  the design  of the filters as simple as possible, it is included  a  second phase detector (6) that receives the reference signal (9) and a  second output  signal (11) coming from the frequency divider (5)  and  shifted 90° with respect to its other output signal (10), and that generates  a second  phase  error signal (13), in quadrature with  the  first  phase error  signal  (12), that is filtered by a second low pass  filter  (7) generating a second filtered phase error signal (15).     The  two  filtered  phase error signals (14,15)  are  taken  to  a quadratic  correlator (8) whose output supplies to the VCO (4) and  its amplitude is proportional to the difference of frequencies between  the reference  signal  (9) and any of the output signals (10,11)  from  the frequency divider (5).

Title: Replicated-in-place internal viscous shear damper for machine structures and components
Inventor: SLOCUM ALEXANDER H
IPC: E04H9/02
Filed: 1993-09-08
Abstract: A means for providing an internal damping mechanism for a system with structural load supporting members (3) that may be subject to time-varying loads, where the structure's structural members have rough holes (4) formed in them, either by casting, drilling, or welding pipe, where the holes can be any shape, but the ideal shape and location maximizes the product of the perimeter of the shape and the distance from the neutral axes to the neutral axis of the structure, so a smooth surfaced shear member (7), with diameter several millimeters smaller than the hole (4) and a surface finish on the order of 0.5 micron Ra, with its surface covered with a very viscous fluid (6), can be inserted into the hole so a replicant, such as epoxy or rubber (5), can be injected around the shear member (7), such that when the structure bends, shear strains occur between the structure and the shear members (7) and this strain occurs across the viscous fluid interface which is very thin because of the use of the replicant, so therefore the energy dissipation rate will be high and bending and axial vibrations will be damped, the damping system being referred to as a replicated-in-place shear damper.
