Title: Agitator configuration
Inventor: MATUSZ GLENN
IPC: A47L9/00
Filed: 2003-04-28
Abstract: The invention is an agitator configuration for a floor care appliance such as an upright vacuum cleaner. The floor care appliance is provided with at least two agitator chambers each having at least one rotary agitator member disposed therein. In the preferred embodiment of the present invention, a vacuum cleaner suction nozzle is provided with symmetric left and right agitator disposed adjacent one another.  A front agitator assembly comprised of a left arid right agitator half-section is disposed in the left and right agitator chambers, respectively. A rear agitator is located rearward of the front agitator assembly and is also comprised of a left and right agitator half section disposed in the left and right agitator chambers, respectively. A plurality of brush members extend from each agitator half-section arranged in a helical pattern around the circumference of each of the agitator-half-sections. The left and right agitator half-sections of the front agitator assembly have opposite helical patterns so that a "chevron" pattern is formed from the front agitator assembly. The "chevron" brush pattern sweeps dirt particles from the center of the suction nozzle along the front of the cleaner toward the suction nozzle's outer edges. Similarly, the left and right agitator half-sections of the rear agitator assembly have opposite helical patterns so that a "chevron" pattern is formed from the rear agitator assembly. The "chevron" brush pattern sweeps dirt particles from the center of the suction nozzle along the rear edge of the suction nozzle toward the suction nozzle's outer edges.

IPC: G06F21/12
Filed: 2002-01-23
Abstract: The present invention discloses a method for enabling at least a part of a Smart Card. According to a preferred embodiment of the present invention, a one time activation code is generated in a server at a telephone operator. The activation code is sent via registered mail to a user of a Smart Card, e.g. a SIM card in a GSM cellular phone. When the user enters the activation code into the cellular phone, the entry is transmitted to the server for verification. Upon successful verification, the server transmits an enabling command to the phone for thereby enabling the intended part of the SIM card. This may be enabling of PKI functionalities that until now have been hidden in the SIM card and thus unavailable for the user. The user may then choose his own signing PIN for authentication, encryption and transaction signing. In case of enabling PKI functions, all necessary generation of private and public keys and establishment of certifications are carried through when the activation code is verified.

Title: Friction modifier alkoxyamine salts of carboxylic acids as additives for fuel compositions and methods of use thereof
Inventor: COLUCCI WILLIAM J
IPC: C10L10/00
Filed: 2003-07-29
Abstract: A friction modifier for combustible fuels is provided that is prepared by combining a saturated carboxylic acid and an alkoxylated amine or etheramine. Furthermore, there also is an additive concentrate for use in fuels, especially in gasoline for internal combustion engines, comprising (a) a friction modifier comprising of a branched saturated carboxylic acid salt of an alkoxylated amine, such as isohexyloxypropylamine isostearate; (b) a detergent package, as well as the combustible fuels containing this additive concentrate. The particular selection of friction modifier (a) enables a stable additive concentrate to be formulated providing a significant benefit in friction loss when incorporated in gasoline used to fuel an internal combustion engine, and hence an improvement in fuel economy. Moreover, the use of the friction modifier (a) in combination with a detergent package permits increased fuel efficiency to be obtained without increasing the incidence of IVD deposits in combustion engines running on a fuel modified with the additive concentrate.
