Title: Digital radio transmission system for a cellular network, using the spread spectrum method
Inventor: KAUFMANN HANS
IPC: H04B7/26
Filed: 1989-09-14
Granted: 1992-03-03
Abstract: A B S T R A C T            A base station (BS) and mobile user stations (MS) each with a transmitter (S), a receiver (E) for multipath reception and a control unit (ST) are provided in each cell. Exactly one set of several sequence sets of the auxiliary function used for spectrum spreading is allocated to each cell. Sequences of several sets in pairs have the property that the absolute values of the normalized periodic cross-correlation functions are much smaller that one and for sequences within a set the cross-correlation function in pairs is optimally small around the zero point. Data synchronous generation of the transmission signals takes place in the base station (BS) for all simultaneous connections and the data clock of the received signal is used as data clock of the transmission signal of the user station (MS).            Application for digital data transmission in building and local areas for the configuration of a so called cordless LAN are considered.      (Figure 4)

Abstract: LOW TENSION PLASTIC CONVEYOR BELT SYSTEM            Abstract of the Disclosure An all-plastic conveyor belt of the type that is collapsible on curves is used in a low tension system, progressing in a helical path around a drive cage or tower. The modules making up the belt have end members with recesses for receiving the heads of plastic rods which hold the modules together.  The heads are thus recessed and will not wear against bars or other components of the drive cage or tower of the low tension system.  The end members of the belt modules in one embodiment are slightly concave for better conforming to the surfaces of the driving tower or cage.

Abstract: A heat pack and a process for its preparation are described wherein the heat pack comprises an earth-like mass between two outer layers surrounding the mass and the two outer layers are joined together by means of holding fibers uniformly distributed over their entire surface area. The joining of the three layers may be effected by a needle bonding process known in the needle tufting process of the textile industry. Webs of the three-layer system needle bonded in this manner are cut into pieces according to their application, thereby forming the heat packs as such, and packaged into foil bags in which the heat packs may be stored and heated.

Abstract: Starting from ground, predominantly carbonate-type raw material which is compressed into briquets and then sintered, it has hitherto been possible to produce high-grade sintered dolomite only in a shaft furnace. The novel process allows the production of briquet sintered dolomite having apparent densities of > 3.20 g/cm<3> with foreign oxide impurities in the sintered dolomite of < 3.5 % in a rotary kiln installation at a temperature of up to 2000  DEG C in the rotary kiln. 
<??>This is achieved by very finely grinding the raw material and charging the briquets prepared from this in a rotary kiln installation to the deacidification unit upstream of the rotary kiln and heating them therein without attrition. A high-grade sintered dolomite is obtained as refractory base material for the manufacture of basic refractory bricks.

Abstract: ABSTRACT Method and apparatus are provided for transmitting, receiving, and reproducing digital audio signals as discrete carriers similar to standard FM broadcast signals. An audio signal is digitized using, for example, adaptive delta modulation techniques. Several channels of audio information, such as left and right stereo channels and a second audio program ( "SAP" ) channel can all be digitized and incorporated onto the digital broadcast signal carrier. The digitized audio signal may be modulated using multiphase modulation of the carrier of an FM broadcast band signal. A plurality of audio channels may be digitized and transmitted over the airwaves, or over a cable transmission network. Channels of nondigitized audio channels may be interspersed with the digitized audio channels. Source material for the digitized audio channels may be provided to a cable headend over the cable transmission network outside the FM band, and rebroadcast over the cable transmission network in the FM band. Advantageously, an "extended" FM band between 72-120 MHz is employed to provide more channels than the "standard" FM band of 88-108 MHZ.
