Title: Internal combustion engine exhaust systems
IPC: F02B77/08
Filed: 1975-09-16
Abstract: 1469390 Monitoring IC engine exhaust gases ROBERT BOSCH GmbH 16 Sept 1975 [17 Sept 1974] 37957/75 Heading G1N The activity of a catalytic reactor 20, Fig. 1 in the exhaust system 21 of an I.C. engine 11 is determined by passing a gas mixture with combustible components through the reactor and measuring the time interval between signals from an upstream oxygen detector 22 and a similar downstream detector 28, said time interval reducing with reduced activity of the reactor. The rate of air supply to the inlet manifold 13 of the engine 11 is measured by a flowmeter 14 and fuel is supplied to each cylinder by an associated injection valve 16, opened in each cycle for a time interval determined by a switching unit 27, controlled in synchronism with the engine by a pulse generator 23. The signal from the upstream oxygen detector 22 is compared in amplifier 25, Fig. 3 with a desired oxygen content signal set by potentiometer 41, 42. If there is a difference this is integrated at 26 to control at 27 the fuel input to the engine cylinders, causing the oxygen content of the exhaust gases to be normally constant. The output from amplifier 25 is also fed to a monostable trigger device 68 which is connected to a switching unit 70 receiving the signal from the air flowmeter 14. When the air-flow is between preset valves a gate 73 passes a pulse which alters the condition of bridge 38 by making transistor 52 conductive. This change switches the output from amplifier 25, alters the fuel supply to the engine and switches the monostable trigger 68 to its unstable state, which sets a bi-stable trigger unit 69. The signal from the downstream oxygen detector 28 is also compared with a reference value to produce an output at 29 when they differ, which is fed to bi-stable 69. If this second signal occurs before monostable 68 returns to normal, a lamp 31 is lit showing reactor 20 is failing.

Title: Improvements in web tensioning arrangements
Inventor: RALPH FREDERICK WALLACE
IPC: B65H23/02
Filed: 1957-12-12
Abstract: 873,431. Feeding webs. WITTON-JAMES Ltd. Dec. 10, 1958 [Dec. 12, 1957], No. 38668/57. Class 100(1) An arrangement for maintaining tension in a web at a substantially constant value, comprises apparatus at the reelstand in which a supply reel of web is mounted, tension regulator means adjustable to determine the web tension, a roller or like web support mounted for movement in a direction transverse to its longitudinal axis and arranged so that the web as it runs from the reel is wrapped partially around the roller, &c., a linkage inter-connecting the ends of the roller, &c., and actuating means adjustable in step with the tensioning. equipment by the tension regulator means for applying a force through the linkage to the roller, &c., in a web tensioning direction. As shown, a web 8, Fig. 2, passes round a roller 11 mounted in arms 26, 27 on a shaft 28. Tension is applied to the web by the roller 11 by means of a pneumatic actuator 23 which actuates the rollers through a rod 36 pivoted to a rod bell-crank lever 35. The lever 35 is connected to a lever 34 carrying a pulley 31. A rope or cable 25 passing around the pulley is connected to the arms 27, 28, the points of connection being adjustable by a worm 37, Fig. 3, rotatable by a rod 40 and handwheel 41. The cable 25 is connected to a plate 101 having a tooth 102 engaging the worm 37, such that rotation of handwheel 41 causes sliding movement of the plate 101 and adjustment of the point of connection. Thus, the roller 11 may be maintained parallel to a line joining the pulleys 29, 30, Fig. 2, when the web is unsymmetrically disposed on the roller 11 and the forces balancing the web tension do not act equally at both ends of the roller 11. If the tension at the edge of the web adjacent the arm 26, Fig. 2, is greater than the opposite edge, the roller takes up the broken line position, the end of the roller adjacent the arm 27 being displaced by the cord 25 to increase the tension at that edge. Variations in tension are detected by a roller 14 so as to vary the braking force exerted by straps 18, Fig. 4, on a web supply roll 3. Each strap is fixed at one end 19 and at the opposite end to a belt tension cylinder 45. Pulleys 44 on piston rods 46 engage the straps while a control valve 48 controls the admission and exhaust of air to and from the cylinder 46. The valve 48 is actuated by a lever 52 carrying an arm 100 and pivoted to an arm 54 connected to an arm 22 carrying the roller 14. The lever 52 is damped by a damper 56, while a piston 64 slidable in a cylinder 65 balances a spring in the valve 48. The actuator 23 is connected to a pipe 60 by a connection X. In a modification, (Fig. 5, not shown) the cable 25 is replaced by piston rods in cylinders actuated by air pressure controlled by a piston slidable under the control of an electric motor controlled by tension detecting means. In a further modification (Fig. 6, not shown) the roller 11 is mounted at each end in a carriage slidable in a guide block.

Abstract: 1,082,758. Measuring thickness of a moving web electrically. CONSOLIDATED PAPERS Inc. Sept.28, 1964 [Oct.3, 1963], No.39475/64. Heading G1N. In a magnetic thickness gauge for measurements on moving webs of material e. g. paper, the material forms a reluctance gap between a detector head 10 (Fig. 3), which contacts one surface of the material and contains a coil 66 on an "E" type core 65, and a ferromagnetic laminated shoe 12 which contacts the opposite surface of the material and completes the magnetic circuit of the coil 66. The head 10 also contains within an annular recess 62, an electromagnet coil 64 which is D. C. energized to urge the head and shoe together thus sandwiching the paper therebetween. The holding force is adjustable by varying the electromagnet current. The head and shoe are pivotally supported respectively by upper and lower carriages which are coupled together and slidable along upper and lower beams by means of an electric motor and a system of pulleys and endless belts. The head and shoe are thereby movable transversely across the web. The detector head is movable to and away from the web surface by a piston type air motor. Change in magnitude of an alternating current through the inductor as its inductance changes may be taken as a measure of thickness; or the inductor may be connected in a bridge circuit, one arm of which includes a reference inductor whereby the unbalance voltage of the bridge is representative of deviation from a standard thickness. The measurements may be fed to a calibrated thickness recorder.

IPC: B29C59/00
Filed: 1960-11-18
Abstract: <PICT:0921276/IV(a)/1> Polyolefin films are subjected in the presence of chlorine and sulphur dioxide to a high voltage electric stress accompanied by corona discharge.  Specified polyolefins include polymers of olefines having 2-6 carbon atoms, e.g. polyethylene and polypropylene, especially isotactic polypropylene.  Treatment may be carried out in the presence of air or other diluent gas, the concentration of chlorine, sulphur dioxide and the other gas being preferably within the area enclosed by the chain-dotted line on the triangular diagram, and especially within the shaded area. Treatment enhances the adhesiveness of the film for synthetic organic polymer coatings, inks and dyes.  The treated film may be coated with a synthetic organic heat seal or moisture proof coating polymer, especially a vinyl acetate polymer or a copolymer of vinylidene chloride and acrylonitrile containing 80-95% vinylidene chloride, 5-20% acrylonitrile, and 0-5% of another monomer, e.g. itaconic acid, methacrylic acid or an alkyl acrylate.  Other suitable polymers are polyvinyl alcohol, butadiene-acrylonitrile copolymers, methyl methacrylate-methacrylic acid copolymers, copolyesters of terephthalic acid and another dicarboxylic acid, e.g. sebacic acid with a glycol, N-alkoxy-methyl polyamides, gelatin, nitrocellulose, vinyl chloride-vinylidene chloride copolymers, vinyl acetate-vinyl chloride copolymers, vinyl acetate-ethylene copolymers and vinyl chloride-ethylene copolymers.  The above are especially suitable as heat seal coating polymers, but may also be used as moisture proof coatings, especially if there is added to such polymers a small proportion of a thermosetting resin precondensate, e.g. a urea-formaldehyde, phenol-formaldehyde or melamine-formaldehyde precondensate, the coating then being heated to induce cross-linking. Alternatively a thermosetting resin precondensate may be used as such.  These coatings may be applied as aqueous dispersions which are dried off under conditions under which the thermosetting resin is cross-linked.  The heat seal or moisture proof coatings are applied by known solution or dispersion coating techniques, preferably as aqueous dispersions. Specification 715,914 is referred to.
