Abstract: A method and apparatus for reuse of pseudo-random noise (PN) offsets within a cell of a wireless communication system such as a multi-sector CDMA system. Adaptive antenna arrays are employed to form the multiple sector areas within the CDMA cell. A forward link data channel is established between a mobile unit and a base station via sectors that share or reuse comment PN offsets, thereby providing desirable transmit diversity.

Abstract: A twofold cleansing method for treating an oleaginous skin condition, which comprises of a dual action system, that when used simultaneously provides essential cleansing benefits for the epidermis. Although this process involves exact amounts of fats, oils, sodium hydroxide, essential oils, grains, vitamins, water, and plant extracts, other ingredients can be added to increase the effectiveness of this process. As well as fragrances may be added to make the scent more pleasant.

Abstract: A wireless system, which minimizes nulls within the wireless system, while simultaneously providing diversity. A wireless system will now have increased capacity and coverage due to an enhanced signal to interference ratio in the areas of beam overlap. The system uses time or frequency offset on the signals input to an antenna to minimize interference in the regions of beam overlap. Additionally, polarization diversity can be introduced using Butler Matrices in conjunction with array elements to enhance the interference reduction.

Abstract: In order to increase a capacity, or a number of mobile stations (MSs), or users, that may engaged in concurrent communication sessions, a communication system is provided that schedules a different MS, or user, in each beam of multiple predetermined, fixed beams associated with a coverage area, in particular a sector. By simultaneously scheduling a user in each beam of the multiple beams, a performance and throughput of communication system is significantly increased over the prior art. In one embodiment of the present invention, a portion of a shared communication channel that is allocated to each MS is concurrently transmitted to each MS via a beam associated with the MS. In other embodiments of the present invention, voice channels, data channels, and control channels associated with each MS scheduled in a beam may be concurrently transmitted to each MS via the beam associated with the MS.

Abstract: Condensing zinc vapor by contacting hot gases containing zinc vapor with a spray of molten lead droplets within a multi-stage condenser with recirculation of the molten lead, wherein the temperature of the lead in an intermediate stage of the multi-stage condenser is controlled to be within the range of from 475.degree. to 515.degree. C, preferably by feeding hot lead from the first stage of the condenser into the intermediate stage via a duct leading through a baffle wall separating the first and intermediate stages.

Abstract: A method and apparatus for detecting the presence of vapor-producing substances such as explosives contained within an item of baggage, in which the item of baggage is enclosed in a chamber and the air pressure in the chamber is varied cyclically in order to mix at least a portion of the air in the item of baggage with that in the chamber. A vapor detector is then used to detect the presence in the chamber air of vapors given off by an explosive substance or drug (e.g., cannabis) contained within the item of baggage.

Abstract: Producing a briquetted oxidic feed for a blast furnace by pelletizing very fine zinc oxide or zinc oxide and lead oxide powder into pellets having an average diameter of from 2 to 10 millimeters prior to briquetting the oxide pellets at a temperature of from 500.degree. to 800.degree.C and a pressure of from 1 to 20 tons/square inch.
