Abstract: According to the invention, methods and devices for increasing cardiopulmonary circulation induced by chest compression and decompression when performing cardiopulmonary resuscitation are provided. According to one method, a pressure responsive inflow valve (24) is coupled to a patient's airway. Chest compressions and chest decompressions are performed. During chest decompression the inflow valve (24) prevents respiratory gases from entering the lungs until a certain negative intrathoracic pressure level is exceeded at which time the inflow valve (24) opens. In this way, the inflow valve (24) assists in increasing the magnitude and duration of negative intrathoracic pressure during decompression to enhance the amount of blood flow into the heart and lungs. Further, the patient is supplied with a pressurized respiratory gas through the inflow valve (24) when the inflow valve (24) opens to ventilate the patient.

Title: Method to prevent specks or hairline cracks in, and premature failure of, airplane cylinder barrels
Inventor: KIM YOON SAM
IPC: C23C22/62
Filed: 2002-04-25
Abstract: The present invention relates to an improved method for the manufacture of aircraft engine cylinder barrels to prevent their premature failure due to hairline cracks or specks thought to be caused by caustic stress corrosion cracking during black oxide treatment. Machined aircraft cylinder barrels immersed into a black oxide chemical bath composed of a solution containing about 60% sodium hydroxide, about 0% sodium nitrate, and about 40% sodium nitrite most effectively prevents specks and hairline cracks. Since residual stresses from machining also contribute to the probability that specks or hairline cracks will occur during black oxide treatment, the maximum selected number of cylinder barrels essentially free of detectible specks or hairline cracks determines the maximum number of cylinder barrels to be machined on a given set of tool bits.

Title: Circuit board mounting system and releasable connector therefor
Inventor: KUPNICKI RICHARD A
IPC: H01R12/72
Filed: 1999-04-16
Abstract: A modular mounting system which allows a circuit board to be removed, inserted or replaced through the front of the mounting frame without deactivating power to the equipment, and in the preferred embodiment without detaching any external cables. Connections for external equipment are disposed along the rear edge of the circuit board, and a row of contacts for the internal connections is provided along the bottom edge of the circuit board. The system of the invention provides a releasable connector which retracts the connector pins into a housing when a circuit board is inserted or removed, thus eliminating the possibility of a contact on the circuit board touching a live connector pin. In the preferred embodiment the external connections are made through adaptors that plug into external cable connectors provided on a connector plate detachably affixed to the rear of the mounting frame. In the preferred embodiment the invention provides an actuating mechanism for the releasable connector which must be actuated in order to remove a circuit board, thus ensuring that the connector pins have disengaged from the circuit board contacts before a circuit board is moved. The mounting system of the invention achieves a high packaging density for mounted devices and accommodates any input/output format. The invention also permits use of two or mare separate circuit boards for a device residing in the same compartment and connected by an interface, which allows circuit boards to be repaired or upgraded by replacing a portion of the device circuitry. The invention also provides a novel system for cooling the mounting frame, providing heat sink tunnels in the impeller airstream and affixing the most significant heat-generating components to the heat sink tunnels. The impeller draws an intake airstream through a low resistance path within the mounting frame to cool the circuit board components.

Inventor: SONNETT JACOB M
IPC: B05B3/06
Filed: 2002-06-18
Abstract: This invention is directed to a cyclonic power system and method of using the system to clean flat surfaces. The cyclone power system includes a driven spindle (60) that is mounted for rotation about its longitudinal axis. There are a plurality of radially extending straight rods (54) extending from the spindle (60). Curved blades (52) are connected at one end to the spindle and at their other end to the free end of a straight rod. The centrifugal force, generated as a result of the rotation of the driven spindle is not effective to cause the straight rods, which are constructed of stainless steel, to lengthen and since the curved blades are connected to the straight rods, the centrifugal force is not effective to lengthen the curved blades. In an embodiment of the invention a perforated disc is secured to the bottom surface of the spindle and to the free ends of the straight rods. In this embodiment the water and debris is pulled up through the perforation in the disc. The perforated disc protects the rotary member from heavy projectiles that are lifted from the surface to be cleaned, adds to the stability to the rotary member and has eliminated of the need for the supports extending between the mid-portion of the curved blades and the straight rods. In addition to the above improvements the flow through the perforations in the disc is limited to the upward flow and once water laden with debris has passed through the perforations in the disc it remains above the disc and is swept to the discharge.
