Granted: 2001-06-05
Abstract: A stuffing box assembly comprising a body which has a bore defined by a generally cylindrical wall and a shaft extending concentrically through the bore. A sleeve is disposed in the bore in surrounding relationship to the shaft, the sleeve havfng a cylindrical portion and an annular flange, the sleeve defining an annulus between the cylindrical portion and the wall defining a bore. At least one and preferably several annular members formed of an elastomeric material are disposed in the annulus. Astop means limits movement of the annular member away from the flange portion of the sleeve, the annular members being disposed between the flange portion and the stop means.

Title: Electrical double-layer capacitor
Inventor: KURABAYASHI KEN
IPC: H01G11/00
Filed: 1990-10-30
Granted: 1995-01-17
Abstract: A B S T R A C T      A gasket (4) or collecting electrodes (1) are used as members for separating the inside from the outside of an electrical double-layer capacitor and small holes (5) are provided therein through which the internal air is drawn.  Thus the  internal pressure becomes lower than the atmospheric pressure and the pressure difference is generated between the inside and the outside.     Due to this pressure difference, collecting electrodes (1) are pressed to solid polarizing electrodes (2).  Hence the resistance in the contacts between the collecting electrodes and the solid polarizing electrodes can be reduced.  Since the contact force is obtained by the pressure difference between the inside and the outside, the contact force is applied equally to every part of the contacts.  As a result, there is no contact where its contact resistance is not reduced.     Further,  there is no need of provision of any device for generating the contact force outside the electrical double-layer capacitor.

Title: Fuel delivery system with capacity monitor
Inventor: LEESON PLATO J
IPC: F02C9/28
Filed: 1991-04-10
Granted: 1995-04-11
Abstract: A fuel delivery system for an aircraft gas turbine engine which provides a monitor intended to estimate, from actual engine starting or operating conditions, whether the fuel delivery system is capable of meeting predetermined operating specifications, such as adequate capacity for a windmill restart.  The differential pressure regulating valve, which is normally provided to maintain a constant pressure drop across the metering valve which meters fuel to the jet turbine engine, has a position monitor associated therewith.  A signal relating to the regulating valve position is processed along with a signal indicating the corresponding actual engine operating conditions, to determine "excess capacity" at the operating condition and estimate from that information whether the engine will likely be capable of meeting worst case demands.

Title: Process for incorporating hologram into laminar structure with wet photograph
Inventor: MAILLOUX DENNIS R
IPC: B42D15/10
Filed: 1991-07-31
Granted: 1999-10-12
Abstract: A laminar structure, for example an identity card, comprises a photograph and a supported hologram.      A moisture-impermeable barrier layer and an adhesive layer are disposed between the hologram and the photograph, so that the photograph can be secured to the hologram while the former is still wet. The supported hologram, the barrier and adhesive layers and the photograph are sandwiched between first and second sheets. The hologram is sufficiently adhered to the photograph that, if an attempt is made to separate the supported hologram from the photograph, fracture will occur within the hologram or between the hologram and its support sheet, so that at least part of the hologram will remain attached to the photograph, so that it is not possible to detach the hologram from the photograph, leaving the hologram attached to the first sheet, and thus substitute a different photograph in the laminar structure.

Title: Process for transmitting additional information with an a.m. radio signal
Inventor: SCHWAIGER KARL-HEINZ
IPC: H04L7/08
Filed: 1991-12-11
Granted: 2000-02-22
Abstract: In order to transmit additional information with an A.M. radio signal, the phase position of an A.M. radio signal carrier is first modulated on the emitter side with a digital, coded additional information signal. On the receiver side, the A.M. radio signal carrier is phase modulated, the recovered additional information signal is decoded and the decoded additional information is used for tuning, switching and/or reproduction purposes. The additional information (PI, PS, AF, AFT, TP, TA, TMC, RT) of the additional information signal is subdivided into a cyclically repetitive number of groups having each two information blocks of the same length. Each information block has an information word and a checking word composes of a determined number of data bits, different offset words being superimposed upon both checking words of each group. These offset words are used on the receiver side for synchronizing the information blocks.

Title: Osteoinductive protein mixtures and purification processes
Inventor: POSER JAMES W
IPC: A61F2/02
Filed: 1992-04-21
Granted: 2002-12-03
Abstract: A method for purifying bone-derived osteoinductive factors including an ultrafiltration process, an anion exchange pro-cess, a cation exchange process, and a reverse phase HPLC process. The ultrafiltration process preferably includes a first ultrafil-tration step using a membrane having a nominal molecular weight cutoff of approximately 100 kilodaltons (kD) and a second ul-trafiltration step employing a membrane having a nominal molecular weight cutoff of approximately 10 kD. For the anion exchange process, a strongly cationic resin is used, preferably having quaternary amine functional groups. Typically, the eluant for the anion exchange process has a conductivity from about 10,260 micromhos (µmhos) (1.026 x 10-2 siemens (S)) to about 11;200 µmhos (1:120 x 10-2S). For the ration exchange process, a strongly anionic resin is used, preferably having sulfonic acid functional groups. The eluant for the ration exchange process typically has a conductivity from about 39,100 µmhos (3.91 x 10-2S) to about 52;700 µmhos (8:27 x 10-2S) or more. The HPLC  process typically utilizes a column containing hydro-carbon-modified silica packing material. The osteoinductive proteins can be eluted from the HPLC column with an acetoni-trile solution in combination with aqueous trifluoracetic acid. The purification processes yield osteoinductively active pro-tein mixtures.
