Abstract: 1319885 Ignition systems; timing ignition ROBERT BOSCH GmbH 27 Oct 1971 [27 Oct 1970] 49854/71 Heading F1B [Also in Division G1] An ignition system for an internal combustion engine has a controllable electronic switch 12 which when triggered induces a high voltage pulse in an ignition coil 16 connected to at least one spark plug 15 and is arranged to be triggered at the end of the unstable state of a monostable trigger circuit 17 which is triggered by the output signal generator 11 coupled to the internalcombustion engine, the duration of the unstable state being controllable in dependence upon the speed of the internal combustion engine for the purpose of adjusting the ignition timing. The trigger circuit is operative to induce a high voltage pulse only after a minimum engine speed has been attained, this being effected in that the unstable period of the trigger circuit coincides with the width of the output pulses of the signal generator when the minimum engine speed prevails and decreases at a greater rate than the width as the engine speed rises above the minimum speed. A further monostable trigger circuit 18 is arranged in parallel with the first trigger circuit and the switch may be changed over by the signal generator for the purpose of inducing the high voltage pulse when the engine speed is below the minimum speed, duration of the unstable state of the further trigger circuit being set to expire at the desired instant of ignition when the minimum engine speed prevails and the two trigger circuits being controllable into their unstable state at the same instant by the signal generator. As shown the signal generator 11 is in the form of a cam operated contact breaker switch 28 whose closing is used to control the trigger circuits 17, 18 into their unstable states. The signal generator can based on the photo-electric principle. The system includes an adjusting voltage generator 27 in the form of a digitalanalogue converter which operates in dependence on the speed of the engine.

Abstract: 1393000 Gas separation LKB-PRODUKTER AB 9 Nov 1972 [10 Nov 1971] 51861/72 Heading B1L [Also in Division G3] A single or multi-stage molecular separator for receiving gas from a gas chromatography column and delivering it to the ion source of a mass spectrometer, comprises an evacuation chamber 2, Fig. 1, coaxial inlet and outlet nozzles 3, 5, and means 13, 14 for moving one of the nozzles axially relative to the other to adjust the spacing therebetween. In use, the molecules, mainly carrier gas molecules, of the gas stream flowing across the chamber 2 towards the outlet nozzle 5 are withdrawn by a pump (not shown) connected to the chamber 2, thereby increasing the concentration of the sample and also reducing the pressure of the gas to the pressure of operation of the spectrometer. If it is desired to reduce or increase the gas flow rate through a normal gas chromatography column or to use a capillary column, a shaft 13 is rotated to cause an eccentric 12 thereon to move a sleeve 14 and attached nozzle 3 axially, whereby the spacing between the nozzles is adjusted to suitably modify the pressure-reducing effect of the separator. For coarse adjustment, a locking screw 15 is slackened and the nozzle 3 is moved relative to the sleeve 14. The nozzles may be brought into contact to eliminate the pressure-reducing effect. The nozzle spacing may be adjusted, in use, in accordance with an output measurement signal. Instead of rotatable shaft 13, the adjustable nozzle may be moved by an axially displaceable rod arranged perpendicular or parallel to the nozzle. Sealing is provided by a sharp-edged ring 9 which presses metal membranes 7, 8 against silver seals 10, 11. In an alternative embodiment, Fig. 2 (not shown), the sealing elements 7 to 11 are replaced by a silver seal (18) and a seal (17) of plastics material.

Abstract: Polyurethanes are prepared by reacting a predominantly linear compound having reactive hydrogen atoms and at least one OH group and a M.W. of 300 to 20,000, a polyisocyanate and if desired a chain lengthening agent and a compound having at least one hydrogen atom reactive with isocyanate groups and at least one anionic salt-type group or group capable of salt-formation, the ratio of isocyanate groups to hydrogen atoms reactive with isocyanate groups in the compounds capable of salt formation being such that the groups capable of salt formation present do not undergo reaction with the isocyanate groups, and the resulting polyurethane is subsequently converted at least partly to the salt form by reaction with an organic or inorganic base in the case where groups capable of salt formation are present, the proportion by weight of the salt type groups contained in the polyurethane being more than 1% and not more than 15% and, when the groups capable of salt formation are carboxyl groups, not more than 8%.  The compounds of M.W. 300 to 20,000 are preferably polyesters, polyesteramides, polyethers, polyacetals or polythioethers and the polyisocyanates are suitably aliphatic, cycloaliphatic or aromatic and may be masked or partially reacted. Suitable chain lengthening agents are glycols, diamines, hydrazines, ammonia, aminoalcohols, mono- and diamino-carboxylic acids and water. The compounds containing at least one reactive hydrogen atom and at least one salt-type group or group capable of salt formation may be a hydroxy- or mercaptoacid, a mono- or diamino-carboxylic acid, dicarboxylic acids, hydroxy- and carboxy-sulphonic acids, aminosulphonic acids, organic phosphorus compounds, addition products of unsaturated acids, unsaturated nitriles, dicarboxylic acid anhydrides, sulphocarboxylic acid anhydrides, lactones, reaction products of olefins with sulphur trioxide, epoxycarboxylic and epoxysulphonic acids, sultones, and disulphonic acid anhydrides with amines, hydrazines, ammonia aminoalcohols and alcohols and hydrazinocarboxylic acids. It is preferred to first form a prepolymer containing excess NCO groups, with or without a solvent and then to react this prepolymer with chain lengthening agents and salt compounds if desired in an organic solvent and/or water. The anionic polyurethane may be converted into the aqueous phase by partially or completely replacing the organic solvent after termination of the reaction and, if desired, salt formation.  Emulsifiers, dispersing agents, fillers, plasticizers and pigments may be added to the aqueous dispersions.
