Abstract: An optical transmitter includes a semiconductor laser which is supplied with a frequency modulated current. An emitted light from the semiconductor laser is modulated in intensity by an intensity modulator in accordance with an information signal and becomes a signal light pulse. The spectral width A v  m  of the light and a power P  s  of the signal light pulse meet the following formulas:     and     where P  th  is a threshold input light power when the stimulated Brillouin scattering begins to occur in the optical fiber in case of no frequency modulation of said light, A v  B  is the Brillouin gain bandwidth of the optical fiber, and Δ v  s  is the spectral width of the signal light in case of no frequency modulation of the light.

Abstract: A circuit for isolating a first low-voltage circuit node from a second circuit node which carries high programming voltages during programming of user-programmable interconnect elements includes a novel two input NAND gate having one input structure configured from high voltage devices connected to the second circuit node. The other input of the NAND gate is a control input for the isolation device and is connected to a low-voltage logic signal which is high when the signal from the high programming voltage node is to be passed through to the low-voltage node and low when the low-voltage node is to be isolated from the high programming voltage node. The output of the NAND gate is connected to the first low-voltage circuit node.

Abstract: A fluidized bed reactor in which housing is defined by a plurality of upright walls, each wall being formed at least in part by a plurality of tubes. A horizontal grid plate extends across the housing and defines a upper combustion chamber for receiving particulate fuel material and a lower plenum for receiving a fluidizing gas, such as air, under pressure. Air is passed upwardly from the plenum, through the grid plate and into the upper combustion chamber to fluidized the fuel material therein and promote its combustion. Fluid is circulated through the tubes to cool the wall portions defining the combustion chamber and the plenum, and an extraction device is provided in the plenum for extracting the fuel particles that backflow from the upper combustion chamber, through the plate, and to the plenum.

Abstract: An active matrix display device comprising two pixel electrodes (41a,41b) in each rectangular area defined by adjacent signal lines (23) and adjacent scanning lines (21). The pixel electrodes disposed across each signal line (23) are connected with respective switching elements (33a,33b), which are connected to the common scanning line (21) and the common signal line (23). In this way, each pixel electrode has only one signal line formed on one side thereof. As a result, a line defect conventionally produced by a leakage between adjacent signal lines through a pixel electrode is prevented. Further, a defective pixel can be easily corrected by short-circuiting the pixel electrode with the adjacent signal line.

Abstract: A method of knitting an upholstery fabric having at least two adjoined contiguous regions of different knitted structures located side-by-side in a wale-wise direction and having courses extending continuously through both regions in which the knitting is carried out on a machine having a pair of opposed independently operable needle beds and in which the needles in each bed can be moved independently of one another in that bed into the path of an operating cam box reciprocal along the needle beds and containing independently operable cam members for each direction of movement of the cam box and in which the camming surfaces of the cam members can be independently altered to affect the loop length of stitches knitted on the needles operated by the cam and in which the needles for one region are actuated by a cam surface in the cam box so as to give stitches with a first loop length and the needles for the adjacent region are operated by a cam surface in the cam box so as to give a second loop length different to the first loop length. The loop lengths of the two adjacent structures are relatively adjusted so that, in the relaxed condition of the fabric, the same number of courses of each of the two regions of different knitted structures in the wale-wise direction extend for substantially the same wale-wise distance.

Abstract: Apparatus (10) for heating and/or cooling a particulate material, e.g. vegetables, by heat exchange with a liquid comprises a horizontal tubular chamber (12) of waisted internal cross-section containing a rotatable mesh cylinder (20) having an auger blade (22) corotatable therein. A row of inlets (A-Q) for heat exchange liquid along the bottom of the chamber are connected via external pipe work to a row of outlets (A′-Q′) for heat exchange liquid at the top of the chamber. Upward flow of heat exchange liquid causes suspension of particulate matter as it is conveyed through the chamber by the auger, thus minimising rubbing contact on the particulate material. The apparatus includes a heating section defined by inlets A-D, a holding section defined by inlets E to L, and a cooling section defined by inlets M to Q, all within a common chamber. Within each section, each outlet is connected externally to the alphabetically preceding inlet except for the leftmost outlet which is connected to the rightmost inlet. The heating and cooling flows recover heat via a heat exchanger (28).

Abstract: The invention relates to a process for continuously separating desirable and undesirable substances in a fibrous suspension, for example for continuously cleaning a fibre suspension intended for the production of paper, board and the like on a paper machine, in which an inflow stream of the fibre suspension is led into a distribution region and is subdivided there into a number of at least approximately equal partial streams, these partial streams then passing through their own a cleaning process, a good stock stream, containing the desirable materials and a bad stock stream ("rejects") containing the undesirable materials being formed from the partial streams by means of a separating process based on the utilisation of centrifugal force and the good stock streams and the bad stock streams in each case being united in a collecting region. The invention is characterised in that the subdivision of the inflow stream of the fibrous suspension into partial streams is undertaken simultaneously for all the partial streams and is thereby effected in a vibrationally damping manner on the fibrous suspension. <IMAGE>
