Patent NO-170790-C (NO)
Inventor: PARRAUD RENE
IPC: H01C7/12
Filed: 1987-12-09
Abstract: A double molded over method of manufacturing a lightning arrester in which a central core 1 is made of zinc oxide in a first step, then two metal end fittings 5, 6 are molded onto the end faces and over the side thereof, and finally a coating of elastomer material 7 is molded around the side wall of the central core and over side portions of the end fittings. The core may be formed of a plurality of smaller section bars of zinc oxide regularly disposed about a longitudinal axis with the end fittings molded onto the end faces and about the sides of the end bars whose end faces are partially metallized. In a further variant, a stack of zinc oxide based pellets having the same cross-sectional area as the core in the first example, with the stack having the same overall length as the core if stiffened by thermal compression with fusible metal inserted between pairs of pellets. The stack assembly is then compressed mechanically in conjunction with heat treatment to effect very good mechanical bonding. The core assembly formed thereby is treated as above.

Inventor: ANTKIW STEPHEN
IPC: G01V5/10
Filed: 1988-01-28
Abstract: In the illustrative embodiments of the invention disclosed, a neutron porosity well logging tool includes a D-T neutron accelerator and a fast-neutron monitor for monitoring accelerator output. The monitor comprises an organic scintillator having a characteristic dimension that is small relative to the average range of gamma ray-induced electrons that would produce high pulses of magnitudes comparable to those resulting from recoil protons produced by source neutrons, while it is large relative to the average range of such recoil protons. The scintillator is coupled via a photomultiplier to a pulse height discriminator circuit that passes pulses in the higher-energy flat portion of the spectrum. Consequently, the neutron source monitor produces a signal that is proportional to the intensity of the neutron source. <IMAGE>

Title: Method and apparatus for detecting changes in raster data
Inventor: BELL ALAN EDDY
IPC: G06T7/20
Filed: 1990-02-26
Granted: 2000-10-31
Abstract: A method and apparatus which provides for the real time comparison of raster data. The raster data is stored in memory such that raster data corresponding to a specific X-Y coordinate location is consistently written to the same memory location. During the process of storing the data in memory, the data currently stored in the memory is read and compared to the data to be written into the same location in memory. If the data is not the same, the discrepancy and location of the discrepancy is noted in a separate area of memory to be used for subsequent analysis and the the data to be written to that location is immediately written into the memory. The method and apparatus of the present invention is particularly applicable to the video graphics environment wherein the current bit of raster image contained in the frame buffer is compared to the updated raster image and the data changes are noted on a pixel by pixel basis. Utilizing the information gathered on the changed pixels, the video display need only update the changed data, thereby minimizing the amount of data to be transferred and increasing the speed of the system. In a preferred embodiment, the method and apparatus of the present invention is employed to provide an interface between a video adapter such as a video graphics array (VGA) and video display system incompatible with the video adapter such as a windowing system whereby the video output generated by the video adapter is translated and input to the video display system for generation of the display in real time.

Inventor: GOTTIER GERRY N
IPC: F25J3/02
Filed: 1991-01-21
Granted: 1994-04-19
Abstract: ABSTRACT The present invention is a process for prefractionating a pressurized, helium-containing feed gas mixture (typically containing helium, natural gas and nitrogen) to produce a helium-enriched stream which comprises the following steps:  (a) the pressurized, helium-containing feed gas mixture is liquefied and subcooled by indirect heat exchange; (b) the liquefied, subcooled,  pressurized, helium-containing feed gas mixture is expanded whereby it is partially vaporized, thus producing a partially vaporized frationation feed stream; (c) the partially vaporized frationation feed stream is stripped in a cryogenic distillation column thereby producing as an overhead, the helium-enriched stream, and a bottoms liquid, the helium-lean stream; and (d) the cryogenic distillation column is reboiled by vaporizing at least a portion of the helium-lean stream.     The present invention is also applicable as an improvement to a process for the production of a crude helium product (i.e., > 30 vol% helium).

Title: Transparent signaling for remote terminals
Inventor: BALES BRUCE MERRILL
IPC: H04M11/00
Filed: 1991-10-17
Granted: 1995-10-31
Abstract: A remote telecommunication terminal providing telecommunication functions identical to those functions provided by local telecommunication terminal directly connected to a telecommunications system via a direct standard link using a standard protocol. The remote telecommunication terminal is interconnected to the telecommunication system through an intervening switching system such as the public telephone network. One such remote telecommunication terminal is a remotetelemarketing terminal.  A remote telemarketing terminal cooperates with the telemarketing system to establish a virtual interface on the telemarketing system. The telemarketing system views this virtual interface as being identical to a physical interface such as one connected to a local telemarketing terminal via a standard link. The remote telemarketing terminal then establishes a virtual link between itself and the virtual interface on the telemarketing system. The virtual link is established on transport channels of standard links that interconnect the remote telemarketing terminal to the switching system and from the switching system to the telemarketing system. The switching system is unaware of the establishment of a virtual link on these transport channels and does not respond to signaling information on a virtual signaling channel of the virtual link. The telemarketing system controls the telemarketing functions of the remote marketing terminal by transmitting signaling information via the virtual interface and the virtual signaling channel to the remote telemarketing terminal in the same manner as the telemarketing system controls alocal telemarketing terminal via the signaling channel of the standard links connected to the local telemarketing terminals. The standard links may be eitherISDN PRI links or BRI links and the standard protocol may be the ISDN protocol.

Abstract: The object of the invention is to provide a device for gripping threaded pipe, and like tubular goods, about their outer diameter, and for applying high torqueforces required for assemble and disassembly of threaded connections, without causing any surface deformation or structural deformation to said workpieces.  The gripping device has an inflatable flexible liner (3) contained within rigid outer shell (5) Axial splines of internal sleeve (7) mate with corresponding splines of flexible liner (3), and distribute torque forces uniformly throughout flexible liner (3). Intro duction of fluid pressure into annular bladder (8), through port (6), causes the flex-ible liner (3) to deform radial inward and thrust friction sleeve (1) into contact with workpiece (4).  Movable anti-extrusion rings (2) prevent deformation of the liner in-to annular space (9), between outer shell (5) and workpiece (4), and also prevent axial wear of flexible liner (3) against outer shell (5).
