Title: Method for allocating a time window within a frame to a mobile accessing a communications cell and base transceiver station using said method
Inventor: DUPUY PIERRE
IPC: H04B7/26
Filed: 1994-03-01
Abstract: Method for allocating a time slot within a frame to a communications mobile accessing one cell from among a set of concentric cells around a base cell which are managed by a transmitting-receiving base station. The time-based uplink structure (112, 122) is shifted with respect to the time-based downlink structure (111, 121) by a delay equal to the sum of a base shift (3.TS) between the base downlink (101) and base uplink (102) time-based structures of the base cell and of a shift time (t1) dependent on the rank of the cell within said set of cells.   Use in radio telephony. <IMAGE>

Title: System and method for cleaning hot fuel gas
Inventor: NEWBY RICHARD A
IPC: C10K1/02
Filed: 1994-04-29
Abstract: ABSTRACT OF THE DISCLOSURE A hot gas cleanup system for removing particulates, alkali and sulfur from fuel gas produced by the gasification of coal in a gasifier, especially in an integrated gas turbine gasification power plant.  A calcium based sulfur sorbent and an alkali sorbent are injected directly into the fuel gas and then recovered,  along with the used sorbent, in a high efficiency, high temperature ceramic barrier filter. The fuel gas  is  then subjected to  further de-sulfurization  in  a polishing de-sulfurizer supplied with a copper based sulfur sorbent.   The used copper based sorbent is regenerated in fluidized  bed  regenerator.    The  regenerated  sorbent  is returned to the polishing de-sulfurizer and sulfur dioxide produced by the regeneration is directed to an oxidizer to which the used and unused sulfur sorbent from the filter is supplied so that the sulfur dioxide can be captured and so that the used sulfur sorbent can be converted to a more stable form for disposal.

IPC: H04L27/34
Filed: 1994-06-09
Abstract: Shaped Signal Spaces in a Simultaneous Voice and Data System Abstract In a simultaneous voice and data communications system, a voice signal is mapped into an N-dimensional signal space constellation as a vector, and added to a reference signal point, i.e., a data symbol, where the data symbol is selected from a constellation of data symbols every signaling interval as a function of a data signal. The constellation signal space is further divided into a number of shaped regions, where each region is associated with a different one of the data symbols. The shape of each region is selected as a function of the characteristics of the voice, or audio, signal. In particular, each region illustratively has a rectangular shape.

Title: Dispensing devices
Inventor: HAYES-PANKHURST RICHARD P
IPC: B65D83/04
Filed: 1994-06-15
Abstract: ABSTRACT    IMPROVEMENTS IN OR RELATING TO DISPENSING DEVICES        A dispensing device 10, for example for pills, tablets or capsules containing medicament, comprises a store part 11 and an operating part 12.  When these are brought into engagement a rib 22 on part 12 enters a narrow recess 34 in part 11 and slidably moves operating member 33 to allow an object 40 to pass through outlet aperture 31 from store 11 and fall into receiving zone 20 in part 12.  The member 33 blocks further dispensing until the parts have been separated and re-engaged.  The movement of member 33 disturbs the objects to assist in orienting them for entry into an assembly channel 37 leading to aperture 31.  An embodiment with a rotary operating member is described (Figs. 1, 5).

Title: Ursodeoxycholic acid-containing medicament in a liquid administration form
Inventor: WIDAUER JOSEF O
IPC: A61P1/16
Filed: 1994-08-24
Abstract: The active agent ursodeoxycholic acid has proved therapeutically active in infants, inter alia for the treatment of cholestatic hepatic diseases. A problem when administering this active agent, a bile acid, to infants is its extreme bitterness. As a result of the present invention a taste-acceptable, liquid administration form for ursodeoxycholic acid with an adequately high active agent concentration is described. The liquid to be ingested is a suspension prepared accompanied by the addition of a swelling and/or thickening agent, which contains the active agent mainly in fine crystalline form as the disperse phase and only in a much smaller proportion dissolved in the aqueous dispersant. A remaining residual bitterness can be additionally masked by the addition of .beta. -cyclodextrin or suitable taste correcting agents.
Patent CA-2131941-A1 (CA)
Inventor: FUKUSHIMA SHINJI
IPC: G03B27/46
Filed: 1994-09-13
Abstract: Extra printing is made possible during a set of ordinary processing operations such as film development and printing.  A film is developed and dried while being fed by a leader attached thereto.  After cutting the leader from the film, it is fed to the printing unit to print the images on the film onto photographic paper.  A plurality of film stocking units are provided in a path from the film drying unit to the printing unit.  Each stocking unit can selectively stock a single film or leave it pass without stocking.  The second film stocking unit can move laterally to change the film track.  If a film requiring a long exposure time is present in the printing unit, the subsequent films that have been developed and dried can be stocked in the other film stocking units.  Thus, continuous film developing operations are not interrupted.

Patent CA-2144421-A1 (CA)
Title: Refined magnesium material and method for producing the same
Inventor: NAKAMURA TADAYOSHI
IPC: C22B26/22
Filed: 1993-09-10
Abstract: A process for producing a refined magnesium material which is flame retardant by adding an alkaline earth metal.          In the process, the dross in a thin film is  formed on the surface of the molten magnesium material by contacting it with a dross-formable atmosphere gas while the molten magnesium material is subjected to a vertical vortex flow. The dross encloses the impurity floating on the surface of molten magnesium material through the vortex flow in a vertical direction. The resultant dross is accumulated at the corner of the crucible to prevent the re-diffusion of the impurity.          The continuous application of the vortex flow against the molten magnesium material causes the thin film of dross to be continuously formed on the molten magnesium material and adhered thereto so as to enclose the impurity each time it is formed. Accordingly, the molten magnesium material is improved in cleanliness or refined.  Solidifying the molten magnesium material by cooling serves to provide an ingot for casting which is extremely reduced  in the porosity peculiar to the addition of an alkaline earth metal. Casting such the ingot serves to provide a product having good qualities.

Title: Strength anisotropy reduction in aluminum-lithium alloys by cold working and aging
Inventor: CHO ALEX
IPC: C22F1/04
Filed: 1993-10-05
Abstract: Strength anisotropy of aluminum-lithium alloy wrought products is reduced by subjecting these types of alloys to improved T8 temper practice. The wrought product, after solution heat treating and quenching, is subjected to a combination of cold rolling and stretching steps prior to aging. The cold rolling can range between 1 and 20 % reduction with the stretching step ranging be-tween 0.5-10 %. The cold rolling step may be performed in one or a multiple of passes. When multiple passes are used, the cold rolling may be done in different directions to further enhance reductions in strength anisotropy for these types of alloys. Table X and Figure 8 summarize the results of inventive practive (D), (E) or (F) on the highest and the lowest (TYS) value and compares it with the conventional practice. The relative closeness of (TYS) by inventive practice suggests commercial exploitation of the wrought Al-Li alloys in high strength applications.
