Abstract: MICROCELLULAR COMMUNICATIONS SYSTEM USING SPACE DIVERSITY RECEPTION Abstract Microcellular stations are transceiving units covering a relatively small geographic area and adapted to establish bidirectional links between mobile telephone subscriber stations and a main base station. Each such microcellular station includes a transmitter for generating outgoing signals directed to the main base station over an optical fiber link. Radio signals received from a mobile station at a separate diversity antenna of the microcellular station are frequency shifted and combined with other signals received from the mobile station. The transmitter at the microcellular station generates an optical carrier signal which is modulated by the resulting combined signals. A frequency converter, located at the main base station, restores the frequency band of signals received from the microcellular station to its original frequency. Frequency shifting and conversion are implemented at the microcellular station and at the main base station by frequency mixing steps performed by oscillators at both locations, which oscillators use the same reference frequency thereby achieving channel coherency.

Title: Process and installation for the electromagnetic casting of rolled bars from an aluminium alloy having a ripplefree surface
Inventor: CARRUPT BERTRAND
IPC: B22D11/01
Filed: 1991-10-29
Abstract: Abstract During  electromagnetic  continuous  casting  of rolled bars from aluminium/magnesium alloys defects in the form of vertical ripples and oxide deposits arise on the bar surface as a consequence of the greatly increased rate of oxidation at the melt surface due to the presence of magnesium in the melt, which defects make it necessary to mill over the rolled surfaces of the bar in the case of stringent requirements with respect to the surface quality of rolled products.        The said surface defects can be prevented using an oxide barrier (26) which dips into the melt head (28), extends at least over the longitudinal sides (x1) of the inductor (12) and is arranged approximately parallel to and at a distance (b) from said longitudinal sides, which oxide barrier is moved backwards and forwards horizon-tally in its longitudinal direction (m).

Title: Method of determining stability of insulating oil
Inventor: SABAU JOHN
IPC: G01N21/68
Filed: 1991-10-31
Abstract: ABSTRACT OF THE DISCLOSURE           The usual method of determining whether failure of a transformer is imminent is to analyze dissolved gases in the insulating oil used in the transformer.  The results of such analysis do not always reliably correlate with the actual failure rate under service conditions.  A relatively simple, accurate method of determining the stability of an insulating oil and thus predicting transformer failure includes the steps of subjecting the oil to ionization, and determining the concentration of free radicals in the oil before and after ionization, the difference in concentration providing a quantitative indication of the gassing tendency or stability of the oil.

Title: Process for petroleum-wax separation at or above room temperature
Inventor: ACKERSON MICHAEL D
IPC: C10G73/02
Filed: 1992-02-10
Abstract: There are disclosed processes for separating faxes of different melting points from a room temperature amorphous or liquid hydrocarbon mixture in an energy conservative manner by selectively causing precipitation of crystallized waxes. The processes involve the use of a selected co-solvent totally miscible with light and intermediate hydrocarbons from a group consisting of acetone, ketene, propanone, 2-propanone, methanol, ethanol, isopropanol, N-propanol, acetic acid, formic acid, and propionic acid or combinations thereof as a precipitating agent. Hydrocarbon mixtures, especially those with elevated pour points are first diluted by solvents such as toluene and/or methylethyl ketone which must be free of any significant quantity of the aforesaid co-solvents. The diluted hydrocarbon mixture at above 50 degrees F is mixed with one or more of such selected co-solvents in a ratio preferably between 1:1 and 10:1 by weight to the heavy hydrocarbon content of the mixture: five minutes or more without solid surface heat exchange cooling is allowed to permit crystallization of waxes which are removed in solid form by a physical process such as filtering, settling, or the like. By controlling the amount and nature of the selected co-solvent and by including or excluding water or brine with the co-solvent, valuable waxes of high melting point may be selectively separated, or all waxes may be removed indiscriminately; performing the separation process in several stages of adding co-solvent and/or water permits selecting out more valuable high melting point waxes first before succeeding stages reduce the wax content of the remaining liquid hydrocarbon to minimal values to enhance its value.

Title: Threshold time dependent logic system for assigning elevator cars
Inventor: BAHJAT ZUHAIR S
IPC: B66B1/18
Filed: 1992-02-25
Abstract: The present invention is directed to notifying a user of an arriving elevator car in response to a hall call registered by the user, wherein notification occurs a threshold time value before elevator car arrival. In the preferred embodiment, an elevator car is assigned to a floor in response to a hall call. The amount of time required for the assigned elevator car to arrive at the floor is determined and compared with the threshold time value. If the arrival time is greater than the threshold time value, the system reexamines assignment, possibly reassigning a different elevator car to respond to the hall call. The arrival time of the assigned (or newly assigned) elevator car is again determined, and this process continues until the arrival time is less than or equal to the threshold time value. When the arrival time is less than or equal to the threshold time value, the hall lantern at the door of the assigned elevator car is energized, e.g., illuminated and/or sounded. Additionally, the hall call is removed from further consideration regarding reassignment to another elevator car, thereby fixing the elevator car assignment In the preferred embodiment the threshold time value can be a constant value determined by, e.g., the building manager. Alternatively, the threshold time value can be variable by the system, e.g., based on the intensity of the traffic as measured by user waiting time or user boarding and/or deboarding rates, whether actual or predicted.
