Patent GB-2462743-A (GB)
Title: A vehicle exhaust carbon filter system
Inventor: GALLACHER WILLIAM
IPC: F01N3/021
Filed: 2009-11-10
Abstract: An exhaust system of a motor vehicle comprising two replaceable carbon filters to each retain only 1% of the carbon from the total exhaust gas flow. The filter is replaced every 1609 km (1000 miles). A filter retaining all the carbon emissions would result in a substantial additional weight of carbon being transported by the vehicle, however a filter retaining only a small portion of the carbon produced would be of an acceptable weight if replaced on a regular basis. Also disclosed is the use of such filters in an exhaust system also having a bypass pipe and a spring loaded pressure relief valve to divert the exhaust flow around the filter if the filter becomes blocked.

Abstract: 752,590. Waveguide impedance networks. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 21, 1954 [April 6, 1954], No. 10098/54. Class 40 (8). Two input terminals A, D are connected by waveguides 1, 2 of equal physical length to two output terminals B, C, the waveguides being coupled at spaced points by couplers 3, 4 whereby the energy from one or both of the inputs can be distributed in a desired manner between the outputs by varying the relative electrical length of the guides between the couplers. This variation may be accomplished by means of an adjustable dielectric block 5 in one of the guides. The energy appearing at either output terminal depends upon the relative phase of the waves transmitted by the two alternative paths provided between each input and each output terminal. The couplers may be 3 db. slotted directional couplers, single-slot E- or H-plane couplers, Magic Tee's or " rat races ". One of the outputs may be terminated by a dummy load so that the device could be used as an attenuator. The electrical lengths of both paths may be varied differentially, e.g. by means of a pair of phase-shifters. Specifications 619,521 and 673,957, [both in Group XL (c)], are referred to.

The gases leaving the reaction zone have an initial temperature of 150-250‹ C. and are washed with 95-99% by weight H 2 SO 4  at 50-120‹ C. If desired this washing may be carried out countercurrently in two stages, the acid circulating in the first stage without cooling. As shown (Fig. 1) and a gas leaving the reactor 15 at about 150‹ to 250‹ C. is delivered to an H 2 SO 4 -washer 1 for drying and removal of dust. The washer 1 is operated at a temperature of from 50-120‹ C. the purified gases leaving at about 60-130‹ C. and passing to stage 2. Washing acid from 1 is delivered to the mixing vessel 11. At stage 2 the gases are cooled by indirect heat exchange to 30-50‹ C., the condensate being delivered to the mixing vessel 11 via receiver 13. The gases leaving 2 are cooled to 20‹ to 25‹ C. by direct heat exchange with condensate from 4 and also if desired from 5, the ratio of liquid HF to gaseous HF being about 0À5 to 1. Condensate from 3 passes via receiver 12 to the mixing vessel 11. From stage 3 the gases are condensed in stage 4 by cooling to the dew point of HF. Further cooling in a two-stage brine cooler 5, 5<SP>1</SP> lowers the temperature to -15‹ to +5‹ C. The resulting condensates, of strength approx. 99À95% HF are delivered to storage vessel 8. Part of the condensate may be delivered to the HF washer 3. Waste gas from the residual gas wash 6 is freed from H 2 SiF 6  in stage 7. In the mixing vessel 11 the condensates and residual wash acid from 1 are concentrated with oleum from 16 and passed to the fluoride reactor 15.

Abstract: 1397044 Contact process METALLGESELLSCHAFT AG 2 March 1973 [21 March 1972] 10366/73 Heading C1A In the production of SO 3  from a stream of gas containing a high percentage of SO 2  by the contact process, part of the partly reacted gas stream being mixed with the incoming gas and cooling between trays or stages of the contact plant, part of the partly reacted gas stream is passed through an absorber for absorbing sulphur trioxide before being mixed with the incoming gas, the rate at which SO 3  is absorbed in the absorber being increased as the loss of catalyst activity increases so that rate of conversion of SO 2  into SO 3  remains constant. Preferably the whole of the partly converted gas stream is passed through the absorber. As shown a contact plant is provided with four catalyst trays 1a to 1d with interstage coolers 2a to 2e between the trays. A high SO 2  content stream A passes in succession through the contact trays and coolers and is cooled after leaving the contact stage at 3, producing a cooled product stream B. A partial stream C is supplied to the absorber 4 where SO 3  is removed at a controlled rate. The resultant stream D is mixed at 5 with the incoming SO 2  stream. Part F of stream C may by-pass the absorber 4 and pass directly to mixer 5.

Title: Production of organosilicon polymers
Inventor: MILLWARD BRIAN BEARD
IPC: C08G77/60
Filed: 1964-03-12
Abstract: Si-containing polymers are prepared by condensing an alkyl ether of a polyhydric phenol with a silane of formula RnSiX4- n where R is an aromatic or aliphatic radical, X is halogen and n = 1 or 2, in the presence of an acidic reagent which is capable of splitting an O-alkyl bond.  The functional groups in the polyhydric phenol ether may be substituents in a single nucleus (e.g. the mono- or di-ether of m- or p-dihydroxybenzene). Alternatively the functional groups may be substituents in different aromatic nuclei which are linked together through one or more atoms or groups (e.g. O or S atoms, amino, carbonyl or methylene groups). The polyhydric phenol ether may be an alkyl ether in which the alkyl group has not more than four carbon atoms.  The acidic reagent may be a Lewis acid (especially AlCl3) or a hydrohalide salt of an organic base. The Lewis acid may be used at about 0.001 mol per mol of polyhydric phenol ether.  The hydrohalide salt of the organic base may be used at 0.1 to 1.0 molar equivalents per ether group of the polyhydric phenol ether.  The R's in the silane may be aromatic (especially phenyl which high temperature resistance is required) or aliphatic (especially methyl). X may be chlorine or bromine.  A reinforcing material (e.g. glass fibres may be introduced during polymerization.  Polymers of formula having recurring units: <FORM:1035099/C3/1> in which each R is an aliphatic or aromatic radical and A is a nitrogen-containing radical which comprises two aromatic nuclei linked through an imino group and which is bonded to the adjacent oxygen atoms by bonds from nuclear carbon atoms.
