Title: Using orthogonal waveforms to enable multiple transmitters to share a single cdm channel.
Inventor: AGRAWAL AVNEESH
IPC: H04W72/04
Filed: 1997-04-01
Abstract: A system and method for enabling multiple transmitters (400) to share a single code division multiplexed (CDM) or code division multiple access (CDMA) channel using orthogonal waveforms. A set of orthogonal channelizing codes Wi(t) is generated, and each transmitter (400) is allocated orthogonal channelizing codes and pseudonoise polynomials in a predetermined manner. The transmitters channelize each user signal using an orthogonal channelizing code Wi(t), and spread each user signal using a pseudonoise (PN) spreading code. Each transmitter employs the same PN spreading codes and time offsets. Additionally, no one orthogonal channelizing code is assigned to more than one transmitter during the time period they are sharing a CDM channel. The spread signals are summed at each transmitter (404) prior to transmission as a composite signal. The offsets are time-precorrected (406, 510) to ensure time alignment at the receivers. The frequencies of the signals are precorrected (408, 512) to ensure frequency alignment at the receivers.

Title: Cyclically lit burner for blast furnace air heater - has gas duct fire bricks coupled e.g. via tongues and grooves to prevent radial movement
IPC: C21B9/06
Filed: 1982-03-25
Abstract: Ceramic burner is for a cyclically operated blast air heater of a blast furnace. It comprises a firebrick burner head at the upper end of the combustion air duct containing a co-axial gas duct which is built up from superimposed layers of fire bricks (12) and may have an oval cross-section. The bricks of each layer are circumferentially offset relative to those of the adjoining layers and are circumferentially intercoupled via complementary vertical grooves (14) and ridges (13) in their end faces (as in common practice) to prevent relative transverse movement. In order also to prevent relative circumferential movement between successive layers, the bricks are further coupled via complementary grooves (17) and ridges (15) at their lower and upper faces (extending radially relative to the gas duct), or with recesses in these faces for refractory dowels. Used for fire brick combustion gas duct for cyclically operating burner of last furnace air heater. The arrangement positively prevents relative movement of bricks due to thermal expansion and contraction which would cause leakage through cracks in the gas duct wall leading to unsatisfactory combustion.
