Title: Optical amplifier

IPC: H01S3/067
Filed: 1986-11-05
Granted: 1989-05-09
Abstract: ABSTRACT OF THE DISCLOSURE         An optical amplifier particularly suitable for use in amplifying signals carried on optical fiber in a select communication band.  The amplifier comprises a resonant optical waveguide cavity which has a core con-taining an active gain material with given absorption and fluorescence spectrums.  The gain material is of the type that preferably has at least two different emission bands originating from the same energy level with one of the emission bands encompassing the select communication band.  The cavity is structured to resonate wavelengths in both emission bands, but with a higher combination of cavity Q and gain coefficient per excited ion for wave-lengths in the emission band not corresponding to the select communication band so that, when pumped, the cavity first lases at this band.  The lasing action causes the atomic population of the gain material corre-sponding to the communication band to remain at a stable constant level where it is available to uniformly amplify by stimulated emission optical signals introduced into the cavity.

Abstract: Abstract A circuit board is manufactured from a core layer having a conductor run layer overlying the core layer on one side thereof, and a continuous layer of dielectric material overlying the conduc-tor run layer, by forming a continuous outer layer of conductive material over the layer of dielectric material.  Material of the continuous outer layer is removed at a predetermined location, and the dielectric material that is thus exposed is also removed so as to form an opening through which the conductor run layer is exposed.  Conductive mate-rial is deposited into the opening to at least the level of the outer conductor layer, whereby the conductor run layer is connected to the outer layer of conductive material.

Abstract: ABSTRACT OF THE DISCLOSURE   The disclosure sets forth a different annular link as the building element; instead of using a split annular link of a 3:1 ratio of link inner diameter to major wire diameter, the link has substantially thinner annulus for forming the rope chain, an annulus that requires an over 5:1 ratio of inner annulus diameter to major wire diameter.  The presently preferred ratio is between 5.2 and 5.7:1.  It is possible to use even thinner annuluses, i.e. having greater ratios, e.g., 7.2-7.7:1 with even greater weight savings (approximately 35%), or other even greater odd-numbered ratios of inner annulus diameter to major wire diameter (e.g. 9.4-9.9:1).  Thus, while there is no theoretical limit, there is probably a maximum practical upper limit to the ratio of inner annulus diameter to major wire diameter.

Abstract: Abstract of the Disclosure:        A protection channel monitoring system for monitoring a protection channel in a digital communication network comprises a transmitter (31) transmitting a check signal converted and split into a plurality of AMI code signals through the protection channel.  The check signal is formed from a pseudo random signal provided by a pseudo random signal generator (15) driven by a pulse signal having a l/M (N being an integer larger than 1) frequency of a clock pulse signal.  The check signal comprises two predetermined N-bit code patterns each comprising logical "0" and "1" level bits.  A receiver (32) receives the split AMI code signals through the protection channel and decode the AMI code signals to the NRZ code signals by sampling technique using a sampling signal being derived from one of the received AMI code signals and having the l/N frequency of the clock pulse signal.  Condition of the protection channel is decided by comparison of the decoded NRZ code signals.

Title: Mineral component/bitumen mixtures prepn
Inventor: CARL ROBERT PETER
IPC: E01C19/05
Filed: 1971-02-01
Abstract: In the prodn. of a mixture of a mineral component, the particle size of which ranges from granular to fine powder size, with a bituminous binder, in which the mineral material is preheated prior to the addition of the bituminous binder, the heating step is carried out in two parallel operations: The corase fraction is heated in a aerated rotary shaft furnace, whilst the powder fraction is heated in an enclosed furnace. Prior to the addition of the binder, the two fractions are mixed together again. The separate heating of the dust eliminates the dust nuisance which is created by the dust laden flue gases from the oil fired rotary shaft furnace. Also, heating of the coarse fraction separately is thermally more efficient. Used for prepn. of e.g. road surfacings and bituminous concrete.

Abstract: A corrugated arrangement (15) is installed in the overdam chamber (3) of a filter tank (1) in such a way that, with the sludge liquor flap (8) being partially opened, direct outflow of the whirled-up granular filter material in the sludge liquor outflow (5) - and hence loss of filter material - is prevented. As a result of the novel arrangement (15), the washing water stream during the washing phase with air and water is quietened in the overdam chamber (3), so that the whirled-up grains can settle on the arrangement (15) and on the fixed bed (2) before the washing water passes into the sludge liquor outflow (5). In this way, it is possible partially to open the sludge liquor flap (8) even during the washing phase with air and water; this is desirable, for example in effluent filtration, in order to discharge relatively heavy suspended materials or to let the washing step proceed within a short time. <IMAGE>
