Title: Control actuator and switch
Inventor: DAVIS ALLEN V C
IPC: H01H35/26
Filed: 1989-12-28
Granted: 2000-03-21
Abstract: ABSTRACT OF THE INVENTION A resilient element such as a thin flat plate or disc spring, commonly known as a "Belleville" spring, which is capable of deflection along an axis normal to its surface is modified to include an amplifying segment disposed in a central aperture in the form of an approximately "W" shaped strip corrected at its ends to opposite positions on the inner margin of the central opening. The central portion of the "W" forms an inverted "U" which is subjected, after positioning within the central aperture, to torquing stress in the plane of the material to bring the ends of the open end of the "U" slightly closer together than the inner edges of the "U" nearest its closed end. One of a pair of Switch contacts is mounted on the closed end of the "U" shaped portion of the device opposite another contact carried on the switch base. Means are provided for applying pressure, normal to the plane of the material, on some position of the peripheral sensing spring in which the ends of the "W" shaped portion connect with the inner margin of thecentral opening of said sensing spring and when such pressure rises to a predetermined level, the "U" shaped portion will snap over to a position in which the contact which it carries will assume an opposite portion with respect to the contact carried by the switch frame.

Title: Identifying earth stresses in acoustic well logging
Inventor: MEDLIN WILLIAM LOUIS
IPC: E21B49/00
Filed: 1991-01-16
Granted: 1998-08-18
Abstract: An acoustic logging tool traverses a fluid-filled cased well with a monopole acoustic energy source.  Pressure waves in the well fluid by the source generate symmetric tube waves in the well casing immediately adjacent the source.  At least one spaced-apart receiver detects these tube waves after they have traveled directly to the receiver through the well casing. Asymmetry imparted to said tube waves as they travel along the well casing by the maximum and minimum earth stresses behind the well casing are identified and used to predict the azimuthal direction of subsequent hydraulic fractures.

Title: Active proximity fuse
Inventor: WITT BENGT
IPC: G01S7/499
Filed: 1992-12-03
Granted: 2003-02-11
Abstract: The invention relates to an active proximity fuse with polarisation-related sensitivity. Radiation (11) which is reflected by particles (10) in the atmosphere towards the receiver (8) of the proximity fuse and which does not originate from reflection at the target (3) has a negative effect on the operation of a proximity fuse.      To reduce this effect, the proximity fuse according to the invention is provided with elements (5) in the transmitter (1) of the proximity fuse for linearly polarising the emitted radiation (6) and elements (12) in the receiver (8) for suppressing the received radia-tion with linear polarisation essentially coinciding with the direction of the linear polarisation of the emitted radiation (6). This arrangement prevents radiation (11) which is reflected by spherical particles (10), such as water droplets, with unchanged polarisation after reflec-tion, from reaching the detector of the receiver, whilst radiation reflected by the target (3) is depolarised and a certain part of the radiation (9) can be detected.

Title: Intelligent call screening in a virtual communications network
Inventor: GUPTA ALOK K
IPC: H04Q3/00
Filed: 1993-07-19
Granted: 1996-11-26
Abstract: A unified and systematic approach is taken both to design of a virtual communications network within a carrier's telecommunications network, and to design the screening filters provided in the VCN data base which control the admission of calls to the network. For this purpose, telecommunications traffic information that is relevant for both the design of the VCN architecture as well as for development of the screening filters is aggregated and applied both to a networkdesign tool that is used to generate the customer's virtual network configuration, as well as to a screening filter generator (SFG). The traffic information may include, for example, traffic data contained in network and customer premises equipment call detail records and billing data. In one embodiment, the SFG also receives outputinformation from the network design tool, indicative of the on-net and off-net locations in the VCN, and information from a carrier data base that provides a weighting factor indicative of the incidence of fraudulent calling to different domestic and international destinations.  The SFG is arranged to jointly process the traffic information as well as the fraudulent calling information (together withinformation relating to VCN design parameters, if desired) in order to generate screening filters that can be installed, and thereafter used, in the VCN to determine, on a call by call basis, whether a call made using the VCN is allowed or denied.Advantageously, the screening filters are designed so that they will minimize orreduce the possibility that the VCN will be used to make fraudulent calls.
