Inventor: SERRI JOHN A
IPC: H04B7/15
Filed: 1998-04-16
Abstract: A method is disclosed for defining a radio frequency map to be used  to  isolate  negative  effects  of  undesirable  radio frequency emitters on radio device communications,  handheld and stationary. The method includes the steps of measuring C-band power corresponding to an L-band beam as part of an L-band  footprint  of  a  communication  satellite,  calculating various identifiable interference errors associated with the signal  transmission  path,  and  subtracting  the  interference errors from the original C-band power measurement resulting in a power value  corresponding to undesirable  radio  frequency emitter interference at the location of the L-band beam.  The resultant radio frequency map can then be used to reallocate frequency channels of operation used by radio devices, mobile phones for example,  resulting in power savings in the radio device while maintaining a suitable signal-to-noise ratio.

Title: Container with integral module for heating or cooling the contents
Inventor: SCUDDER JAMES A
IPC: A47J36/28
Filed: 1996-10-16
Abstract: A container for holding a material, such as food, beverage or medicine, includes a cap and a container body. The container body has a material cavity (214) unitarily formed with a reactant cavity (216). The reactant cavity contains a solid reactant (246), and the cap (212) contains a liquid reactant (236) that, when mixed, produce an endothermic or exothermic reaction, depending upon the reactants selected. The cap has a tubular body section with an actuator disc (228) closing one end and a breakable barrier (234) closing the other end. With the exception of the barrier, the cap is of unitary construction. The cap has one or more prongs (230) extending from the inner surface of the disc toward the barrier. When a user depresses the actuator disc, it flexes inwardly and moves the prongs toward the barrier. The reactants mix when the prongs puncture the barrier. Heat transferred between the two cavities heats or cools the material. The wall (244) of the container that defined the reactant cavity may be pleated (216) or corrugated to promote heat transfer.

Title: Twin feed screw
Inventor: BECHER ULRICH
IPC: F04C18/08
Filed: 1996-07-08
Abstract: In known embodiments, media are fed in a contact-free manner in propeller pumps by single-thread twin feed screws which are guided via pilot gears, the twin feed screws having the same transverse profile with a core circle, tip circle, an involute flank and a hollow flank, enabling the pump chamber to be divided into axially staggered cells and thus obtain high pressure differences in one stage. In addition to dynamics, efficiency and production, the control of the medium is also determined by the contour of the end profile, the variation of which improves all the dependent variables. According to the invention, the involute is replaced by a curve which does not rise constantly and has a central saddle region and a smooth connection to the core circle. The variations in the end face achieved thereby improve the dynamics and volumetric efficiency and extend the possibilities for controlling medium at the end face. The detailed adaptation to the new curve together with the smooth connection at the base point enable the core and flanks to be produced jointly by a single tool. Feed screws with profiles of this type are suitable for flow rates of between 100 and 100 m3/h and ultimate pressure of < 0.05 mbar at speeds of rotation of approximately 3000 min-1 and approximately 50 % efficiency.

Abstract: A mobile cellular telecommunication network is disclosed having a plurality of cells between which are defined reuse regions each served by a plurality of directional antennas each at respective base stations located around the reuse region boundary. Means are provided for allocating all uplink channels at all antennas in all reuse regions. Further means are provided for determining boundaries of microcells within the reuse regions, a plurality, equal to or greater than the plurality of antennas, of microcells being served by each antenna in the reuse region. Further means is provided for allocating to each microcell a group of uplink channels in an orthogonal reuse pattern within the reuse region. Means for ascribing a position to mobile terminals within each reuse region is provided. Yet further means is provided for allocating uplink channels for use by a mobile terminal from the group allocated to the microcell which contains its ascribed position.      Since all channels are reused at all antennas, all channels are reusable several times in all cells, greatly increasing the number of mobile terminals which may operate without reducing cell size or requiring additional base stations.
