Abstract: A support pillar system for a magnetically-shielded room includes several support pillars, each support pillar including a nested structure formed by a first structure and a second structure surrounding the first structure.     The upper end of the first structure has a threaded part, and a fastening member provided with a thread and disposed about the threaded part. The shielding structure of the magnetically-shielded room is attached to the second structure of the support pillar, whereby the floor of the room is supported on the upper end of the first structure.      When the member provided with a thread is tightened in a locking position, it locks the first structure and the second structure together, whereby the vibration of the floor is transmitted to the shielding structure and the shield vibrates substantially in synchronization with the vibration of the floor of the room. When the member is threaded into an open, unlocked position, the locking of the second structure is released vis-a-vis the first structure, whereby the inner room is allowed to vibrate, irrespective of the vibration of the other shield structures, and hence, the potential vibration of the room is not transmitted to the shielding structures.

Abstract: An opener for use in varying ground conditions, ranging from no-till to conventional full tillage conditions, includes an adjustable down pressure control and a down pressure spring and tension link assembly which selectively provide a limited free float opener condition or a conventional down pressure spring controlled bias condition. A sleeve slidably received by the opener arm and mounted over the lower portion of the tension link assembly allows the opener to free float in loose soil conditions so that only the weight of the opener provides downward bias when the down pressure control is adjusted to a minimum condition. The opener is free to ride up and down to follow irregularities in the ground surface. In harder soil conditions such as those encountered in no-till farming methods, the down pressure control is adjusted to a position wherein an enlarged portion on the sleeve bottoms against the opener arm and the spring begins to compress so that the opener operates in the conventional spring biased mode. The sleeve allows increased downward movement of the opener to follow depressions in the soil.

Granted: 2004-09-07
Abstract: A method of determining an electric conductivity of an earth formation formed of different earth layers, whereby a wellbore containing a wellbore fluid extends through said formation, is provided. The method comprises lowering a n induction logging tool into the wellbore to a location surrounded by a selected one of the earth layers, the tool comprising magnetic field transmitter mean s suitable to induce magnetic fields of different frequencies in said earth layers, and magnetic field receiver means suitable to receive response magnetic fiel ds at different spacings from the induction means and to provide a signal representative of each response magnetic field. At least two of said different frequencies and at least two of said different spacings are selected, and for different combinations of each selected frequency and each selected spacing, the transmitter means is operated so as to induce a magnetic field of the selected frequency in said earth layers, which magnetic field induces a corresponding response magnetic field near the tool. The receiver means is operated at the selected spacing from the transmitter means so as to provide a signal representing the response magnetic field. Th e signals are combined in a manner so as to create a combined signal having a reduced dependency on the electric conductivity in the wellbore region and t he electric conductivity of an earth layer adjacent the selected layer.

Title: Improved client-server architecture using internet and guaranteed quality of service networks for accessing distributed media sources
Inventor: CIVANLAR MEHMET REHA
IPC: H04N21/239
Filed: 1997-06-10
Granted: 2001-05-22
Abstract: An improved client-server architecture of the present invention utilizes the advantages of known QOS networks to provide guaranteed quality of service, security, and a charge mechanism for handling requests initiated over a packet network, such as the Internet, for access to distributed media sources. Such media sources may be independent of the QOS network provider and may be located by browsing the Internet. A method of operating a client-server network enables the system level merger of the Internet and a guaranteed QOS network, such as the public switched telephone network, in order to provide the users with a complete information superhighway today. It will appear to the average user that the Internet and QOS network are fused together. Thus, when a user, connected to the Internet, selects an application that requires functionalities offered by the telephone network, such as guaranteed QOS delivery of media information or customized billing, the Internet-resident application will communicate information to a server, which will in turn initiate a session over the QOS network for delivery of the required information to the client using client information transmitted from the client (or from the application) to the server over the established Internet session. The client information may includea client account number, login and password, and/or phone number to enable the server to establish the switched network connection to the client. Accordingly, media sources which are separate and independent from the QOS network provider may be accessed using a secure, guaranteed QOS network in a manner providing for ease of identification and billing.
