Title: Method and apparatus for detecting an eas marker using wavelet transform signal processing
Inventor: ERDOEL NURGUEN
IPC: G01S13/74
Filed: 1995-08-01
Abstract: Wavelet transform processing is performed on an input signal received  at  a  receiver  circuit  of  an  electronic  article surveillance  (EAS) system.   The input signal includes a target signal generated by an EAS marker and also includes correlated high amplitude interference signals.  The wavelet transform processing is performed so as to generate from the input signal plural wavelet transform signals having mutually different phases.  The wavelet transform is substantially phase invariant with respect to the interference signals and lacks phase invariance with respect to the target signal.  Uncorrelated components of the plural phase-diverse wavelet transform signals are identified to detect the target signal.

Title: Neon fluorescent lamp and method of operating
Inventor: JENNATO SCOTT D
IPC: H01J61/067
Filed: 1995-08-30
Abstract: A nearly pure neon is described along with a method of operating the lamp.  A phosphor is coated on the lamp wall. By properly stimulating the neon, ultraviolet light may be emitted, that can stimulate the phosphor to a first light emission.  The lamp may then be operated to produce a visible light emission that is the result of neon emission or of intermediate combinations of the neon and phosphor emissions.  A single neon lamp may then produce in one instance, an amber color, or in other instance, a red color without the cold environment problems typical of a mercury based lamp.  The output efficiency is enhanced when the lamp is formed as an aperture lamp.  The narrow source is also useful as a source in reflector and lens systems.  High pressure neon lamps offer a small source size, direct color with no filtering, good tolerance of impact and jarring, moderate cost, and increased vehicle styling potential.

Title: Process for the alkylation of olefins and apparatus carrying out this process and others
Inventor: ALEXANYAN GEORGY G
IPC: B01F5/04
Filed: 1994-07-25
Abstract: Disclosed is a process of the alkylation of an olefin with an isoparaffin using sulphuric acid as a catalyst. In this process, a finelydispersed emulsion of isoparaffin and sulphuric acid is prepared first, in a separate emulsion preparation zone. This preparation is carried out by injecting the isoparaffin into the acid through a set of nozzles, thereby allowing the isoparaffin to "scavenge" at high speed through the acid and thus to form an extremely homogeneous emulsion. This makes it possible to achieve proper mixing without need of impellers or other similar mixing devices that usually call for substantially maintenance and operating costs. Then, the emulsion that was so prepared and which forms an already "finished" phase per se, is fed into a reaction zone which is separated from the emulsion preparation zone and in which the olefin is injected preferably at a plurality of points and in directions perpendicular to the emulsion flow. Advantageously, such as injection can be controlled so that the volume ratio of sulphuric acid to hydrocarbons present within the reaction zone is as low as from 0.3 to 05:1. This process allows reduction in the rate of expenditure of the raw materials, especially sulphuric acid, through the way and ratios at which the materials are mixed, and through the use of a proximate analysis of the alkylation reaction process; it also improves the target product quality. An optimized, small-size, high-capacity and ecologically-clean apparatus for carrying out this process is also disclosed.
