Title: Apparatus for improving the signal to noise ratio in wireless communication systems through message pooling and method of using the same
Inventor: JAVITT JOEL I
IPC: G06Q30/06
Filed: 1995-12-01
Abstract: Apparatus for improving the signal to noise ratio in wireless  communication  systems  through  message  pooling including hardware, software and protocol contained within a packet data communication system which enables a wireless communication  system,  for  example  an  electronic  display system,  to adapt communication techniques to meet customer based accuracy requirements independent of changes in the signal  to  noise  ratio  of  the  communication  channel  and methods of using the same.  Communication having low signal to   noise  ratios   are   improved   using   intelligent retransmissions of the communication signals and statistical detection or demodulation.  Such techniques are particularly useful when used in wireless communication in unbalanced systems, such as electronic display systems.

Title: Method for n-cyclopropylation of aromatic amines, as well as compounds and compositions obtained
Inventor: SOMFAI EVA
IPC: C07C227/08
Filed: 1994-07-12
Abstract: Process for the introduction of a cyclopropyl group into a primary or secondary aromatic amine or into heterocyclic compounds containing a secondary nitrogen atom reacting to the corresponding amines or their salts so as to form the corresponding N-cyclopropyl-(1'-carboxy)-derivatives either with the reagent of general formula (I), optionally in the presence of an acid binding agent or with 2,4-dihalogen-butyric acid ester or with chloroacetic acid ester, whereupon the resulting N-(alkoxy-carbonyl)-methyl-derivative is treated with alkali alkylate and dihalogen-ethane to convert the alkoxy-carbonyl-methyl group into a carbalkoxy-cyclopropyl group and subsequently optionally hydrolysing the ester groups if present and optionally eliminating the 1'-carboxyl group introduced in the course of the first step, whereby the last step is carried out optionally after introducing other substituents into the aromatic ring or after eliminating other substituents from the aromatic group. The method is suitable to synthesize 1-cyclopropyl-7-piperazine-1,4dihydro-quinolone-3-carboxylic acid derivatives. New biologically active compounds are formed including compounds of formula (IV) and their salts which are used in pharmaceutical and veterinary compositions.

Patent CA-2193040-A1 (CA)
Inventor: GRACE JEREMY M
IPC: G03C1/30
Filed: 1996-12-16
Abstract: The present invention comprises a polyester film support in which the surface has been subjected to an energetic treatment to produce carboxyl groups on the polyester surface. The treated surface is then coated with a dilute solution of carboxyl reactive hardener and solvent (e.g., water) or a blend of carboxyl reactive hardener and gelatin and solvent (e.g., water). After drying the hardener or hardener/gelatin coated support, a photographic emulsion is coated on the surface. The resulting film element has excellent adhesion of the photographic emulsion after photoprocessing. Furthermore, the support coated with hardener/gelatin blend is safer to coat and handle than previously known methodsinvolving grafting of hardener directly to the support.
