Title: Multi-Fuelling an Engine
Inventor: COURTOY PIERRE
IPC: F02D19/10
Filed: 2008-02-28
Abstract: A compression ignition engine is supplied with a first fuel in a flow of air and a second fuel is injected into the combustion chamber. The first fuel comprises a more volatile fuel than diesel such as ethanol, LPG or other combustible gas; the second fuel comprises diesel or biodiesel; and the second fuel is injected in multiple pulses in each ignition cycle with the first pulse acting as a pilot pulse to trigger ignition, and the timing of the second pulse being such as to modify the temperature through evaporation of the second fuel and thereby reduce the combustion temperature and mitigate knock susceptibility. Preferably the pilot pulse is followed by a single further pulse of the second fuel in the ignition cycle. The engine may be controlled to operate in two different modes, one mode for light and medium load conditions when there is only a pilot pulse injection of the second fuel which reduces NOx and soot emissions, and the other mode for higher load conditions when there is a pilot pulse injection followed by a main pulse injection of the second fuel. The first fuel may comprise bioethanol and or one or more of the following: ethanol, butanol, propanol, lpg, natural gas, hydrogen.

Title: Symbol to sub-carrier interleaver for DVB-T2 using odd interleaving
Inventor: TAYLOR MATTHEW PAUL ATHOL
IPC: H04J11/00
Filed: 2008-10-24
Abstract: DVB-T and DVB-H interleave symbols to sub-carriers using a pseudo random sequence generated using an LFSR (linear feedback shift register) 200 whose bits are fed through a permutation matrix 210 to generate the read address for a partitioned interleaver memory. The invention provides improved separation between symbols by using an odd interleaving process only (fig 9) for successive sets of data symbols, when the number of data symbols which can be carried per OFDM symbol is less than half the maximum that can be carried. Data symbols to be transmitted are sequentially written into the memory and read out using generated address. Applying a cyclic offset to the address that changes from symbol to symbol reduces the likelihood that successive data bits which are close in order are mapped onto the same sub-carrier of an OFDM symbol.

Title: Improvements in or relating to electro-acoustic devices
IPC: H04R13/00
Filed: 1939-03-31
Abstract: 527,100. Telephone transmitters and receivers. STANDARD TELEPHONES & CABLES, Ltd., and ROBERTSON, J. S. P. March 31, 1939, No. 10113. [Class 40 (iv)] The diaphragm is held in position only by the attraction of the magnet system which comprises a single pole of one polarity beneath the centre of the diaphragm and one or more poles of opposite polarity and of material of high coercive force disposed symmetrically around the central pole, thus producing a magnetic flux more or less radial. The magnet system may comprise a U-shaped or cup-shaped permanent magnet 22, Fig. 2, or Fig. 6 (not shown), of high coercive force with a central pole 23 of nickel iron alloy having 35 to 45 per cent. nickel. The diaphragm 25 rests on an annular seating 29, a membrane 28 of mica or waterproof material and a cover 27 with sound apertures 39 being arranged as shown. A plate 30 having apertures corresponding to the pole-pieces is arranged airtight behind the diaphragm, or the space behind the diaphragm may be filled in with a sealing compound, in order to leave only a small volume of air behind the diaphragm. The connections to the coil 24 are made through disc terminals 33, 35 separated by insulation. The casing 21 is provided with three pins 42, Fig. 4 (not shown), which can be fitted into a bayonet holder in an airman's face mask. The central polepiece and coil may be of substantially rectangular section, Fig. 7 (not shown). In an airman's transmitter, the resonant frequency of the diaphragm is made about 2000 c/s by adding acoustic stiffness behind the diaphragm, e.g. by the plate 30. This may be modified by a silk-covered aperture arranged in the flange of the casing, Figs. 8 and 9 (not shown). The stiffness of the air between the diaphragm and the membrane 28, or between the membrane and the cover, raises the response up to 2700 c/s. This may be arranged to compensate for the effect of the ring pads by which a receiver is held against the head of the user, the frequency characteristic being flat up to 3000 c/s. Specifications 481,351, 481,740 and 513,529 are referred to.

Title: Improvements in or relating to electron multiplier circuits
IPC: H01J43/30
Filed: 1942-07-28
Abstract: 559,021. Electron multiplier circuits. FFENNELL, H. S. MOLYNEUX-, BOSCH, F. J. G. VAN DEN, and VACUUM-SCIENCE PRODUCTS, Ltd. July 28, 1942, No. 10567. [Class 40 (v)] In an electron multiplier circuit of the kind in which a source of high potential is connected across a resistance potentiometer having tapping points connected to the output electrode, secondary cathodes and primary cathode, there is provided a feed-back to the primary cathode from a point in the potentiometer which is at a greater positive potential in relation to the negative side of the source of supply than the value of the normal grid bias, and means for applying to the grid a potential relative to the negative side of the source such as to provide the required grid bias potential. As shown in Fig. 2, the primary cathode 11, secondary cathodes 16 and 18 and the anode 19 are connected to tappings on a potentiometer 20 connected across a source of potential 21 in series with a resistance 26. A second potentiometer 27 feeds the accelerator 14 and, through the tuned input circuit 25, the grid 13. The anode feeds an output circuit 22. With this arrangement, on an increase in anode current the potential of the cathodes tends to rise thus causing a further increase in anode current. However due to resistance 26, the potential across potentiometer 27 falls and the potential of the accelerator and the grid is reduced to compensate the increase in anode current and the instability is removed. The compensating effect is increased by the resistances 28, 29 between the cathode and grid. In a modification, Fig. 3 (not shown), the invention is applied to an electron multiplier used as a frequency changer in a superheterodyne receiver. In this case, the second potentiometer is dispensed with and the accelerator is connected to an independent source of constant potential. Specification 545,123 is referred to.
