Title: Automatic control of hydrocarbon catalytic reactions
IPC: B01J8/24
Filed: 1956-12-27
Abstract: 817,970. Automatic control systems for catalytic processes. ESSO RESEARCH & ENGINEERING CO. Dec. 27, 1956 [Dec. 27, 1955], No. 39290/56. Class 38 (4). In catalytic conversion apparatus for paraffins and naphthenes boiling in the approximate range 100 F. to 900 F. the temperature or space velocity of the reactants is controlled automatically by the response of a capacitance cell measuring the octane number of a feed stream to the apparatus. In Fig. 1 a supply 11 of paraffins and naphthenes containing small amounts of aromatics and boiling in the range 100-500 F. is mixed with a supply of hydrogen 18 and passed through a heater 13 having natural gas burners 14. The heated mixture passes into a reaction zone 23 provided with a bed of a platinum catalyst 24 on an alumina support so that aromatics and other products of octane number than that of supply 11 are produced and passed to a fractionation zone 26 having a steam heater 27 and means, not shown, for refluxing, condensing and cooling. Light fractions are taken off through line 28 and heavier fractions pass through line 29. A portion of the heavier fractions is routed through a constant-temperature bath 32 and a capacitance cell 34. Deviations in the octane number of these heavier fractions from a desired value thus vary the capacitance of cell 34 to alter the frequency of a beat frequency oscillator 38 associated with a crystal oscillator 37 so that the difference frequency influences a controller 45 to correct the octane number by adjustment of an electrically or fluid pressure operated valve 20 controlling the supply of mixture to heater 13 or by adjustment of a valve 17 controlling the supply of fuel to burners 14. Alternatively, by closing valves 30a and 36a and opening valves 10 and 7, valves 20 and 17 are controlled in correspondence with changes in the octane number of supply 11, In a fluidized cracking arrangement, Fig. 2, hydrocarbons boiling in the range 100-900 F. are supplied through a conduit 58 and mixed with a catalyst supplied through a conduit 69 from a regenerator 87. The mixture is supplied through a grid plate 53 to a reaction zone 50 having a stripping steam supply 56 and dip separators 51. The spent catalyst is returned through conduits 60, 62 to regeneration zone 87, air for transport and combustion in the zone being supplied through conduit 63. The regenerated catalyst from dip separators 65 passes into conduit 69 and the combustion products pass out through conduit 67. The output from reaction zone 50 is supplied to fractionation zone 74 producing gaseous fractions at 75, petrol fractions at 76 and heavier fractions at 77. The octane number of the petrol fractions is automatically stabilized by a capacitance cell controller 80, similar to that of Fig. 1, adjusting valve 59 to control the hydrocarbon supply, valve 70 to control the catalyst supply and valve 61 to control catalyst regeneration.

Title: Refuse disposal
IPC: C02F11/10
Filed: 1973-08-21
Abstract: 1446876 Refuse disposal systems MANNESMANN AG 21 Aug 1973 [23 Aug 1972] 39624/73 Heading F4B In a process for disposing of industrial refuse, domestic refuse and sewage sludge, the industrial refuse is broken down by indirect heat to form a coke, the sewage sludge is mixed with the coke and the mixture is de-watered and burnt with the domestic refuse. The industrial refuse contains materials, such as plastic, difficult to burn without releasing harmful smoke and gases. It is fed via hopper 1 to a rotary oven 2 where it is reduced to a fine-particle coke continuously discharged at the lower end of the oven and quenched in water tank 3. The quenched coke is fed through a magnetic separator for ferrous constituents to a mixer 13 where it is stirred with the sewage sludge which has been heated at 14. The gases given off during coking are collected in a chamber 4 and passed to gas purification apparatus consisting of, for example, a separator 5, a wet washing stage 6, removing HCl, a desulphurization stage 7, and a hurdle washer 8. Part of the hydrochloric acid is used to acidify the sewage sludge. H 2 S from stages 7 and 8 is converted to sulphur in an oxidizer 9. The purified gas passes over line 10 back to heat the oven 2. The combustion gases from the oven are passed via a steam generator 11 to a chimney 12. The coke-sludge mixture from mixer 13 neutralized by the addition of lime milk passes through a settler 16 and a centrifuge 18, which removes part of the water 2, to the feeder 19 of a rotary oven 20 in which it is burned together with domestic refuse. Some of the purified gas is used to provide extra heat in oven 20. Water from the settler 16 and the centrifuge 18 is supplied to a filter 17 using coke from the oven 2 as filter material. When spent this is passed to the centrifuge and combined with the main stream of mixture going to oven 20. The ash from oven 20 passes through a magnetic separator 22 to a tip; and the combustion products from chamber 23 are used to heat a steam generator 24 before being passed to the chimney via a dust extractor 25. The revolving coking oven 2, Fig. 2, is tubular and has heating ducts 31 in its acid-resistant lining. Connection 32 supplies the purified gas and connection 32 removes the combustion products.

Title: Truck
IPC: B60R21/00
Filed: 1974-09-11
Abstract: 1479051 Collision protection in road vehicles MITSUBISHI JIDOSHA KOGYO KK 11 Sept 1974 39711/74 Heading B7B  The load carrying part of a truck is free to slide longitudinally relative to the truck frame when an impact force greater than a given size is imposed on it. An hydraulic arrangement then plays at least a part in abosrbing the kinetic edergy of the carrier. The truck bumpers together with plastic deformation of the truck frame can thus play a more effective part in protecting the cab occupants from the effects of collision.  As illustrated in Fig. 4, the carrier 1 of a dump truck can move longitudinally by the deforming action of its pivot pin 63 on slots in mounting plates 62. During each longitudinal movement, energy is absorbed by the piston and cylinder unit 401 which is normally responsible for tipping the carrier. The energy absorption is effected by the forced passage of oil through a piston by-pass 407. In modifications (not shown), the pivot pin mounting has bolts which can move by deforming slots, or the mounting can cam out of a depression against a resilient bias. In another embodiment, the carrier is normally fixed relative to the frame by U-bolts and by plates which shear when there is a sufficient relative force between the carrier and the frame. Energy is subsequently absorbed by a piston and cylinder unit 100 (Fig. 2) which has a perforated piston and which is connected between the carrier and the frame. Further energy is absorbed by the action of a layer 5 of friction material interposed between the carrier and the frame.

Abstract: 1,019,010. Regulating I.C. engines STANDARD MOTOR CO. Ltd. Oct. 23, 1962, No. 40017/62. Heading F1B. In an I.C. engine control system the regulating action of a governor is modified to reduce the maximum fuel supply rate progressively as the engine speed setting of the governor increases to increase the rate of "torque backup" for a portion of the speed range. With speed increase movement of governor plate 11 in direction of arrow A is transmitted by rod 13, hook 14 and pin 15 to rotate lever 16 and fuel valve spindle 17. The governor speed setting is adjusted by rod 26 which rotates lever 20 and cam 27 to vary the bias applied by spring 24 to governor plate 11. Downward movement of governor plate 11 is transmitted through spring 18, sleeve 19 and pin 15 to rotate lever 16 counter-clockwise thus increasing the fuel supply until lever end 28 engages cam 27 after which further movement of governor plate 11 has no effect on the fuel metering valve. The control may be applied to fuel injection or carburetter engines. In a modification the setting of cam 27 may be adjusted manually by a flexible cable.
