Abstract: Aromatic compounds are alkylated with C20-C1300 olefinic oligomers by contacting the oligomers and aromatic compounds with an acidic catalyst to produce novel alkylated aromatic hydrocarbon compositions useful as lubricant basestock and additives. The olefinic oligomers used as alkylating agents are prepared from 1-alkene oligomerization in contact with a reduced chromium oxide catalyst on silica support. In one embodiment, the aromatic compounds are alkylated with a mono-olefinic HVI-PAO dimer which is prepared as a product or by-product from 1-alkene oligomerization using reduced chromium oxide on solid support. The alkylated aromatic hydrocarbons retain the unique features of the alkylating olefinic oligomer and exhibit high viscosity index and low pour point. The novel alkylaromatic compositions show improved thermal stability; also, the compositions are useful as lubricant additives for improved antiwear properties, antioxidant and other properties.

Abstract: An   improved  freight  brake  emergency  valve  device providing  improved  stability  against undesired emergency brake   applications   without degradation  of  emergency sensitivity.    This  is  achieved,  in  one  aspect of the invention,  by  introducing a spring force on the emergency piston  as  the  piston  approaches  emergency  position to thereby  retard the piston momentum sufficiently to allow a random  brake  pipe  pressure fluctuation to dissipate.  In another  aspect  of  the invention, a choke and check valve are  arranged  to  create a dashpot effect to retard piston momentum  resulting  from  a  random  brake  pipe  pressure fluctuation.

Abstract: A two-stage method of producing N2O5 in nitric acid from N2O4 in nitric acid consists of a first production stage in which the anodic oxidation of N2O4 in nitric acid and cathodic reduction of nitric acid are separated by a non-ionic or anionic ion exchange membrane, and a second production phase in which the product of the first stage anodic reaction is subjected to further anodic oxidation, the anodic and cathodic reactions being separated by a cationic ion exchange membrane. The use of a cationic membrane in the second stage promotes, through leakage of N2O4 to the catholyte, an increase in N2O5 concentration and decrease in N2O4 concentration within the anolyte acid whilst avoiding a significant loss of current effieciency. The two stages may be connected in series and operated continuously to produce a nitric acid solution containing typically 32 wt% N2O5 and less than 2 wt% N2O4.

Title: Differential doppler velocity gps receiver
Inventor: BRAISTED PAUL E
IPC: G01S11/10

Granted: 1994-05-24
Abstract: THE ABSTRACT    To reduce error introduced by the local oscillator in the velocity calculations, the receiver has two "tracking channels" and a microcomputer.  With numbers required to, simultaneously, lock each of the "tracking channels" each to a respective satellite signal, the microcomputer employs a differential doppler technique to calculate the receiver velocity.  The microcomputer calculates a number which represents the difference between the apparent doppler frequency shift of the carrier signal which is transmitted by the first "tracking channel" satellite and which is measured over a specific time period and the apparent doppler frequency shift of the carrier signal which is transmitted by the second "tracking channel" satellite and which is measured over substantially the same time period.

Abstract: A facsimile device includes an automatic receiving function, in which, after the facsimile device is connected to a line, users can store a match pattern suitable for the connected line.  At the stage of production of this facsimile device, no match pattern for an automatic receive mode is stored in this facsimile device, or alternatively, several match patterns corresponding to ringing signals employed in several countries are stored independent of destinations of the facsimile device.  This facsimile device includes a characteristic setting mode.  In this characteristic setting mode, this facsimile device detects a ringing signal from the line connected thereto and determines characteristic values of the detected ringing signal.  The facsimile device sets the determined characteristic values in a match pattern employed in practice for determining whether or not there is a ring to call the facsimile device in the automatic receive mode.          Thus, even if installed in any of a plurality of countries, or connected to a PBX that outputs an extraordinary ringing signal, this facsimile device can perform the automatic receiving function.
