Abstract: An earth cooled distribution transformer system and a method of cooling same and distributing electrical power to a plurality of consumer loads (31) is described. A distribution transformer (10 is provided with the primary (16) and secondary (17) windings encapsulated in a solid insulating material. The steel magnetic core (13) remains exposed and the transformer is buried in ground at a predetermined depth with the core (13) exposed whereby heat generated by the windings is dissipated into the earth through the exposed magnetic core. The high voltage supply cable (20) may be a buried cable or is at least partly buried as well as the power distribution cable (21), which feeds power to one or more consumer loads. The power distribution transformer (10) may be buried adjacent a manhole enclosure (12) with the primary and secondary winding power cables being connected to terminals (22-25) accessible in the manhole. A series of power distribution transformers (10) and supply cables (20) as well as feed cables (12) may be buried in ground in a network to feed an entire residential area without the need to provide insulating casings or even manhole enclosures.

Title: Voltage regulator circuit
Inventor: FLORENZ HANS-JOERG
IPC: G05F1/575
Filed: 1999-03-03
Abstract: A voltage regulator circuit for generating a regulated output DC voltage from a non-regulated DC or AC voltage, comprises an input rectifier circuit for rectifying the non-regulated AC voltage and a series regulator, containing a gate-controllable transistor, which regulates the output voltage supplied to it by the rectifier to a first voltage value. The transistor of the series regulator is a field-effect transistor (20) which in the ON condition charges a charging capacitor (46), the charging voltage of which forms the regulated output voltage. Connected to the gate terminal (21) of the field-effect transistor is a first threshold circuit (26, 28, 30, 32) receiving the non-regulated DC voltage which applies to this gate terminal (21) a voltage turning OFF the field-effect transistor (20) as soon as the non-regulated DC voltage exceeds a predetermined threshold value. Furthermore, connected to the gate terminal (21) of the field-effect transistor (20) is a second threshold circuit (36, 38, 40, 42) receiving the regulated output DC voltage which applies to this gate terminal (21) a voltage turning OFF the field-effect transistor (20) as soon as the regulated output DC voltage exceeds a predetermined design value.

Title: Time management & task completion & prediction apparatus
Inventor: PALKA THOMAS
IPC: G06Q10/06
Filed: 1999-03-30
Abstract: A computer software application in the form of a software management and task completion and prediction apparatus by which project completion can be ascertained and management of a project can be maintained with a high efficiency and accuracy.  The software application is a web-based application which enables users to proactively manage and accurately predict strategic software development and deliverables. This application and delivery management system comprises distributed data collectors, an application server and a browser interface. The data collectors automatically gather data already being generated by various tools within the organization, such as scheduling, defect tracking, requirements management and software quality tools. This data is constantly being collected and fed into the application server, thereby providing objective and updated information. New tools can be easily added without disrupting operations. The data collected is fed into the applications server which is the brain of the apparatus. The application server analyzes the data collected by the data collectors to generate a statistically significant probability curve. This curve is then compared to the original planned schedule of product delivery to determine if the project is meeting its targets. Based upon this comparison, the software application predicts a probable delivery date based upon the various inputs and variables from the development process. In addition, the application server also generate early warning alerts, as needed and indicated. At such time as the software apparatus identifies a potential problem, the alerts automatically inform the user, so as to mitigate a crisis and assist with resolution of the problem. The alerts are communicated to the designated user by e-mail.

Filed: 1998-03-05
Abstract: In a communication system that transmits diversity messages (an original message followed by one or more copies thereof), a selective call receiver (10) which receives an original message and one or more copies will display only one of the received messages and discard the others without displaying them. This is accomplished by storing in a memory (30) the identification tag of the message that was displayed and deleted. The identical identification tags carried by later copies of the same message are compared to the stored identification tag. If a match is found, this indicates that an earlier version of the received message has already been displayed and deleted, whereupon the received copy is discarded.
