Title: Device for transferring a signal between two end points which are movable relative to each other
Inventor: PERSSON DAN
IPC: H01R35/02
Filed: 1993-03-29
Granted: 2000-03-07
Abstract: A device for transferring a signal between two end points between which a coiled conductor, contained in a substantially circular cassette, is arranged. At least one of the two end points is movable relative to the other. The cassette consists of two parts, a stationary stator (11) and a turnable rotor (12). On the stator (11) there is arranged a holding element which is under spring force and has a free end which is fixed in the assembled position of the cassette in tensioned state on the rotor (12). The holding element is detachable from the rotor (12) by rotation of the latter, so that, in the operating position of the cassette, it protrudes, in released position, through a space of the cassette, separated from the latter.

Abstract: A time-division multiplex switch (100) switches a hierarchy of data rates. It sets up higher-rate connections not as a plurality of individual lowest-rate connections but as one or more time slots in each one of a plurality of sequential frames (40, 50) that correspond to that higher rate in each superframe (30).  A time-slot-interchangeswitching element (131, 141) of the switch utilizes a plurality of physically orlogically distinct double-buffered data memories (301,302, 303) each corresponding to a different one of the superframe and different-size ones of the frames.  Reading and writing of each of the data memories' buffers alternates with the corresponding one of the superframe and different-size frames; reading of a data memory's buffer immediately follows writing of that buffer.  Information from all incoming time slots is written into each one of the data memories, but only information corresponding to the data rate of an individual data memory's corresponding frame size is read from that data memory into outgoing time slots.  A control memory (305) maps memory locations of the data memories to output time slots.  A corresponding control architecture in a switching element (1700) of a time-multiplexed switch (120) uses a control memory (1701) that maps input ports to time slots of an output port.

Title: Capacitively coupled rf fluorescent lamp with rf magnetic enhancement
Inventor: GODYAK VALERY A
IPC: H01J61/56
Filed: 1993-10-14
Granted: 2005-01-04
Abstract: A fluorescent light source includes a fluorescent lamp having first and second electrodes at or near the ends thereof for capacitive coupling of RF electrical energy to a low pressure discharge within the fluorescent lamp and an RF source having a first output lead electrically coupled to the first electrode and a second output lead electrically coupled to the second electrode. The electrodes include circuitry for inducing an RF magnetic field within the fluorescent lamp in the region of the electrodes. The RF magnetic field improves the performance of the capacitively coupled RF light source by creating an auxiliary inductive RF discharge near the capacitive coupling electrodes. The inductive discharge locally increases the plasma density and the electrode sheath capacitance and provides a reduction in RF voltage across the capacitively coupled fluorescent lamp.

Abstract: A gas-filled three-electrode overvoltage arrester may be developed in such a manner that it has dependable "fall-safe" and "vent-safe" behavior.  For this purpose, a two-arm spring clip  (10)  is fastened to the center electrode (1).  The ends of the two-arm spring clip (10) rest, with the interpositioning of a spacer (20, 21; 22, 23), against the ends of the end electrodes (2, 3).  The end of each arm of the spring clip bears a cap (14, 15) which is provided with a flange-like edge (16, 17).  One end of the connecting wire (6, 7) of each end electrode has the shape of a ring (61, 71) which is fastened at the end side to the end electrode.  The ring of the connecting wire and the flange-like edge of the cap are opposite each other and are held apart by a disk-shaped fusible pellet (20, 22) and a cylindrical part (21, 23) having insulating properties.   The cylindrical part consists either of a temperature-resistant insulating material or of a metal-oxide varistor.

Title: Method and composition for preserving core sample integrity using an encapsulating material
Inventor: COLLEE PIERRE EMMANUEL
IPC: E21B25/08
Filed: 1994-04-20
Granted: 2005-03-01
Abstract: The present invention provides a method for maintaining the mechanical integrity and for maximizing the chemical integrity of a core sample during transport from a subterranean formation to the surface, the method involves cutting and encapsulating a core sample with an encapsulating material that increases in viscosity or even solidifies, at temperatures slightly lower than those expected downhole, or relatively early in the transport process.      A preferred encapsulating material contains at least one polyglycol or chemically modified polyglycol from the oxyalkylene polymer family. The specific formulation of the encapsulating material differs depending upon the expected downhole conditions.     For example, the encapsulating material can include a thickener, a nucleating agent, and a water swellable material or another inert material that is capable of sealing the core sample against water.      A preferred nucleating agent would serve both as a heat transfer agent and a crystallization trigger, and therefore would speed up the rate at which the encapsulating material would solidify or increase in viscosity, particularly downhole. The encapsulating material should either solidify or increase in viscosity enough to protect the mechanical integrity and maximize the chemical integrity of the core sample for analysis at the surface. The chemical integrity of the core sample can be further maximized by using the present invention in conjunction with a pressure core barrel.

Abstract: A composite support frame structure for the construction  of  a  seat.    The  support  structure comprises a rigid continuous rod-like frame formed in a closed loop and having opposed diverging rod-like side members which lie in a common plane and opposed rod-like end members formed integral with the side members.   At least one of the end members is arced outwardly.   A belt of  substantially non-extensible material forms a slightly truncated sleeve, narrower than the frame, to apply a compression force between the side members and to flex the arced end member. The sleeve is retained in tension about the opposed diverging  rod-like  side  members  by  the  restoring spring force between the side members exerted by the arced end member.

Granted: 1997-03-04
Abstract: The sideframe of a railway car truck are constructed such that basic overall sideframe appearance is maintained, but the actual construction results in a more efficient use of the materials as a means of reducing the sideframe weight. This means that material is used according to how the stresses are encountered by the sideframe, dictating that the sideframe midsection is structurally heavier than the sideframe ends. Maximization of this construction is provided by shaping the entire sideframe into a solid, unitary cross-sectional ?-beam shape. A solid top flange of the ?-beam corresponds to the typical top compression member while the solid bottom flange corresponds to the typical bottom compression member. The solid vertical web, which interconnects the top and bottom flanges is a typical, thereby allowing the web to absorb forces which would normally have to be absorbed by either top or bottom member. This feature allows the sideframe to be lighter, yet structurally stronger because the top and bottom members can now be cast dimensionally smaller. To take advantage of the weight savings even further, the ?-beam shape has a structurally tapering thickness from the midsection to the ends and this corresponds to the loading experienced by the sideframe. The open, ?-beam exterior allows for easier and more reliable inspection, as well as improved casting quality due to a substantial reduction in casting core usage.
