Title: Method and system of combining signals in a telephone conference circuit
Inventor: PAFFENROTH DARRYL
IPC: H04M3/56
Filed: 1992-04-17
Abstract: A method for combining signals for a telephone conference may include a multiplicity of identical adders for combining six signals and providing a single combined output. The adders may be arranged in a repeatable hierarchical scheme in which each group of six conference members includes an adder for combining all six signals, with the output of this adder being provided to other groups of six so that each conference member receives signals from every other conference member. As few as three hierarchical levels of addition may be used with up to 216 members. Adders may also be arranged so that a member of a first conference may monitor other conferences without affecting the first conference.

Title: Silicon or Silica Substrate with a Modified Surface, Process for Producing the Same, New Orthoesters and Process for Producing the Same
Inventor: GUIDOTTI BRUNO
IPC: C07D303/12
Filed: 1993-07-06
Abstract: The silicon or silicon dioxide substrate of the present invention have a novel modified surface which is occupied by the alcohol moiety of an orthoester. Said alcohol moiety can be saturated or unsaturated. The modification is effected by treating the surface of the substrate with an orthoester.      Thereby, the water is eliminated by hydrolysis form the surface, and the formed alcohol or silylether therafter takes the place of the water. Particularly suitable are new orthoesters of the general formula R1C[OCH2-CH2-O-CO-CH2CH2]3, wherein R1 is hydrogen or a cleavable organic residue, and R is (CH2)n, n being an integer form 1 to 18, and new orthoesters of the general formula (see formula I) wherein R1 is hydrogen or an organic residue, R3 is hydrogen or an alkyl group of 1 to 6 carbon atoms; and R4 is hydrogen, an alkyl group or a phenyl group. The modified surfaces have an increased boundary or contact angle and thus a reduced wett-ability. Moreover, they can react via reactive substituents with other monomers or polymers. This kind of surface modification advantageously replaces the silanization used so far for glass and other silicates.

IPC: H01R43/26
Filed: 1993-07-09
Abstract: A system is provided for firmly attaching a coaxial cable terminus to a standard connection jack in such a way that the connection point is effectively shielded from tampering by individuals and is effectively sealed from degrading elements in the atmosphere.  The system includes a jack attachment member having a collet structure, a swagging shell which slips over the collet structure to accomplish a firm connection with the jack and a single or preferred multi-chamber locking shroud which surrounds the swagging cylinder so as to make it difficult to de-attach and/or re-attach the cable terminus to the jack without special tooling.  The preferred multi-chamber locking shroud of the invention makes it even more difficult to de-attach and/or re-attach the cable terminus to the jack without special tooling.  The use of the locking shroud and especially the preferred shroud further makes it difficult to break off the locking shroud by twisting the shroud, such as with a pair of pliers.  Such special tooling, however, is simple and inexpensive for authorized service technicians, thereby making the system at once relatively secure from tampering and atmospheric degradation and simple and inexpensive to install and maintain.  Furthermore, the system can be retrofitted into existing coaxial cable equipment, using standard coaxial cable connection jacks.

Title: Method for calculating sedimentary rock pore pressure
Inventor: HOLBROOK PHIL
IPC: E21B47/06
Filed: 1993-10-04
Abstract: An improved technique more accurately determines pore pressure of sedimentary rock penetrated by a borehole from the earth's surface. Formation overburden is directly measured at one or more locations in the borehole, and a log of formation overburden is generated using the measured overburden pressures and conventional geophysical data. A linear relationship has been determined between the logarithm of effective stress for a specific mineral and the logarithm of solidity, which allows the maximum effective stress and the compaction exponent for that mineral to be determined. This linear relationship enables the effective stress and compaction exponent for rock comprising a combination of minerals to be precisely determined at multiple borehole intervals. The effective stress and overburden calculated according to the techniques of the present invention are particularly useful to geologist and well planners in the oil and gas industry.

Abstract: Disclosed is a method for the rapid quantitative determination of low density lipoprotein(LDL) in a biological fluid sam-ple containing LDL, very low density lipoprotein (VLDL) and high density lipoprotein (HDL). The sample is first passed through a matrix to bind LDL to the matrix. The LDL is then eluted from the matrix diferentially from VLDL and HDL. A parameter representative of the concentration of a solute exiting the matrix during the interval when LDL is eluted is then determined, wher-ein the parameter is proportional to the amount of the LDL in the sample. The parameter may be determined, e.g., by electroni-cally integrating under a spectrophotometrically detected peak of eluted LDL.
