Title: Rapid shutdown and ecology system for engine fuel control systems
Inventor: MCCARTY ROBERT S
IPC: F02C7/22
Filed: 2002-06-06
Abstract: A dual function rapid shutdown and ecology system for fuel delivery systems for engines, specially aircraft gas turbine engines, is disclosed. The dual function is accomplished in a single module operated by a single electromagnetic solenoid valve commanded by the engine electronic control unit. Upon actuation of the solenoid valve, a large spring loaded piston strokes to the extreme of its travel creating a cavity having a volume sufficient to accommodate all fuel leftover in the fuel manifold and distribution system at shutdown, thus preventing atmospheric pollution or engine damage upon subsequent operation. Simultaneous with actuation of the solenoid valve, fuel pressure differentials cause a small piston to stroke to the extreme of its travel opening fuel passageways and causing all the fuel being delivered to the engine combustion chamber to bypassed back to pump inlet, thus effectively accomplishing the rapid shutdown function. An alternate embodiment allows for use of the dual function system on engines employing low pressure differentials along the various stages of the fuel control system manifold or where the ecology function is not required.

Title: Cigarette filter
Inventor: FIGLAR JAMES N
IPC: A24D3/16
Filed: 2002-07-30
Abstract: A cigarette filter that includes a multiple section filter which reduces the level of predetermined smoke constituents. The filter (130) consists of a fibrous filter plug (132) located at the mouth-end of the cigarette, a section (136) containing a selective adsorbent material, and a section (134) containing a general adsorbent material. The selective adsorbent material, such as a phenol-formaldehyde resin matrix surface-functionalized with mainly primary and secondary amine functional groups, removes specific smoke constituents from the tobacco smoke. The general adsorbent material, such as activated charcoal, is preferably capable of adsorbing a range of chemical compounds without a high degree of specificity. Structurally, the fibrous filter plug, the selective adsorbent section, and the general adsorbent section are axially aligned in tandem.

Abstract: A combustion-powered driving tool for driving nails or other fasteners in which the starting characteristics of a motor in the tool are improved by varying the amount of voltage applied to the motor when starting the motor and during normal operations so that the motor is driven to reach the rotational speed required in normal operations quickly. Therefore, the combustion-powered driving tool does not require the use of an expensive low-inertia motor, but can use a relatively inexpensive core-type motor or the like with inferior starting characteristics, while improving the work efficiency and user-friendliness of the combustion- powered driving tool.

Abstract: An information assistance service automatically updates contact information in a subscriber's contacts folder or private directory. The information assistance service receives changes to its public telephone number database, which includes name, telephone number, postal address, and possibly e-mail address, compares the information in the contacts folder to be updated with the changes to the public database, and replaces the information in the contacts folder with new information if the telephone number is included within the changes to the public database. The subscriber may choose to be notified before or after such replacement is made - if before, the user may approve the changes one-by-one or all together. The updating can be performed in substantially real-time, as soon as changes to the public database are received, or the updating can be performed less frequently than those changes are received.  In the latter case, the changes made to the public database since the last update are kept track of. Alternatively; shadow record information about a contact may be derived when a contact is added to a contacts folder, and an intelligent search may be performed using the shadow record information to update the contact record.

Patent CA-2490355-A1 (CA)
Inventor: CARDENO MARK
IPC: G01N33/80
Filed: 2002-06-19
Abstract: Microvolume liquid dispensers that provide simple and inexpensive approaches to making cytology microarrays. In some embodiments, the dispensers comprise tips that comprise an outer sleeve, typically shaped like a funnel, that holds a reciprocating needle or pin. The tip of the pin slightly extends beyond the distal opening of the outer sleeve in one position, and is retracted in another position. When the pin is in the distal position the pin contacts the inner surfaces of the sleeve and blocks cytology liquid from flowing through the opening of the sleeve. Thus the pin and sleeve cooperate to form a reservoir behind the blockage. When the pin is pushed up into the sleeve, for example by touching the tip to a glass slide, a passage is formed between the outer surface of the pin and the inner surface of the sleeve. The liquid in the reservoir then flows through the passage and onto the slide. Removing the tip from the substrate moves the pin back to its original position, re-forming the reservoir and leaving a predetermined microvolume amount of the liquid on the slide.
