Title: Trailing arm suspension with wrapper compression axle mounting
Inventor: PIERCE WILLIAM C
IPC: B60G/
Filed: 1996-08-02
Abstract: A vehicle axle has mounted thereto a vehicle component, such as a brake actuator, a radius rod or track bar tower or a suspension for mounting the axle to the vehicle frame through an axle wrapper band which uniformly compresses the axle to provide a substantial frictional force between the axle and the wrapper band of a magnitude to prevent any appreciable translation or rotational movement of the axle with respect to the wrapper band in normal service on a vehicle. The axle can be round or multi-sided and the wrapper band has a corresponding shape. The wrapper band can be formed in parts, for example, U-shaped or L-shaped halves, and compressed towards each other before joining the halves either by welding or by a mechanical attachment. Alternatively, the wrapper band can be unitary in nature, heated and press-fit onto the axle. The wrapper band applies compressive pressure uniformly to the axle along mutliple angularly spaced axes and minimizes or eliminates the need for welding the components to the axle.

Title: System and method for automatic critical event notification
Inventor: SHABOT MYRON M
IPC: H04W84/02
Filed: 1996-08-07
Abstract: A critical event notification system continuously monitors patient statistics and lab data to detect critical events, and automatically pages a responsible physician or physicians, each having an alphanumeric pager. In particular, a computer is used to continually access real-time data and multiple hospital databases which are periodically updated. These databases include patient chart databases, databases corresponding to patient history and databases maintained by various labs. The computer, preferably a clinical information system, is automatically provided with certain data, or periodically extracts it from other, relational databases. The computer automatically reviews this data, makes the critical event determination, and formulates an alphanumeric message that is informative as to the patient's condition and the reasons why a critical event was detected. After automatically retrieving from a database a personal identification number ("PIN") for a remote pager of each physician responsible for the patient, the computer automatically establishes modem contact with a paging network, and causes the network to page each responsible physician and transmit to them the alphanumeric message. The alphanumeric message preferably indicates patient name, diagnosis, the event prompting the page, and the name and return telephone number of medical personnel at the hospital who are attending the particular patient. The system also has widespread applications outside medicine.

Title: Cooled gas turbine blade
Inventor: FUKUNO HIROKI
IPC: F02C7/18
Filed: 1998-06-12
Abstract: The present invention relates to a cooled blade of a gas turbine, and in particular an object of the present invention is to reduce thermal stress around air-transpiration holes (4) provided for shower-head cooling of a leading edge portion of a blade.      A number of air-transpiration holes (4) are provided at a leading edge portion (2) of a cooled blade (1). Cooling air flowing through a cooling air passage (15) formed inside of the blade blowout to the blade surface of the leading edge portion (2) of the cooled blade (1) by way of the air-transpiration holes (4), to thereby shower-head cool the surface of the leading edge portion (2). In the conventional blade, the air-transpiration holes (14) are formed obliquely to the leading edge portion (2), whereby acute-angled portions (30) are formed at inlet/outlet ports of the air-transpiration holes (14) in the leading edge portion (2), and thus cracks due to thermal stress develop around the air-transpiration holes (14). In contrast, according to the present invention, the air-transpiration holes (4) are formed so as to extend substantially orthogonal to the leading edge surface of the cooled blade (1) such that the acute-angled portions are eliminated, whereby thermal stress can be reduced and thus the cracks can be prevented.
