Title: Communication line transient protection
Inventor: SMITH DAVID C
IPC: H04B3/00
Filed: 1987-08-07
Granted: 1992-03-31
Abstract: COMMUNICATION LINE TRANSIENT PROTECTION            Abstract The severity of the problems of transmitting high speed data over a regular twisted wire pair are legendary. These problems arise from a variety of conditions, including the capacitance of the wire (which increases with length) and the propensity of unshielded wire to pickup high induced voltages. An arrangement is disclosed that is suitable for short, as well as long, wire distances and which also effectively eliminates the interference problem caused by induced voltages, including those caused by electro-static discharge. This arrangement passes two twisted wire pairs through a series of ferrite cores. The twisted wire pairs coming out of the ferrite cores are terminated such that one of the pairs is connected to ground while the signal carrying twisted pair is connected to a small signal balun coil, pulse shaping circuit and low pass filter.

Title: Manifold seal structure for fuel cell stack
Inventor: COLLINS WILLIAM P
IPC: H01M8/24
Filed: 1987-11-25
Granted: 1991-10-08
Abstract: Abstract Improved Manifold Seal Structure For Fuel Cell Stack The seal between the sides of a fuel cell stack and the gas manifolds is improved by adding a mechanical interlock between the adhesive sealing strip and the abutting surface of the manifolds.  The adhesive is a material which can flow to some extent when under compression, and the mechanical interlock is formed providing small openings in the portion of the manifold which abuts the adhesive strip.  When the manifolds are pressed against the adhesive strips, the latter will flow into and through the manifold openings to form buttons or ribs which mechanically interlock with the manifolds.  These buttons or ribs increase the bond between the manifolds and adhesive, which previously relied solely on the adhesive nature of the adhesive.

Title: General cancer-associated scm-recognition factor, preparation and method of use
Inventor: CERCEK BORIS
IPC: A61K47/48
Filed: 1988-03-04
Granted: 1995-07-25
Abstract: The invention relates to a cancer recognition factor (SCM-factor), its use and method of preparation. The SCM-factor of the invention is characterized as a low molecular weight peptide which is distinguished by its ability to produce a ten percent to fifty percent decrease in the intracellular fluorescein fluorescence polarization value of SCM-responding lymphocytes derived from the blood samples of donors afflicted with cancer. The SCM-factor is also characterized by its ability, after prolonged contact with SCM-responding lymphocytes, to modify the SCM-response of lymphocytes from donors not afflicted with cancer so that such lymphocytes respond in the SCM-test in all respects like lymphocytes from donors afflicted with cancer. The SCM-factor is isolated from a body fluid such as blood or urine by first subjecting the body fluid to ultrafiltration through a filter with a 1000 Dalton molecular weight cutoff. Following ultrafiltration the filtrate may be lyophilized or stored at 4°C or immediately purified by elution with distilled water through a chromatographic column and collecting elution fractions of between 0.3 and 0.5 Ve/Vt. The collected fractions may be further purified by elution with aqueous ammonium bicarbonate through a chromatographic column saving the elution fractions of between 0.4 and 0.6 Ve/Vt. If desired the samples may be even further purified by passage through a column packed with anion exchange material followed by reverse phase high pressure liquid chromatography purification. The SCM-factor is used for general screening of blood samples for the presence of malignancy in the donor body.
