In a fluid amplifier, high-pressure and lowpressure cells 22, 23 are separated by a flexible member 21 connected to a vertically movable shaft 36 aligned at its lower end with a control orifice 37. A pressure line 30 flows through orifice 71, 72, chamber 73, conduit 74, through orifice 37 into pressure chamber 75, conduit 76 and chamber 77. Chambers 73, 77 are divided by a diaphragm 80 which controls, through conduit 81, ball valve 86. In use, a decrease in pressure in chamber 23 causes shaft 36 to move downwardly closing orifice 37, thus increasing the pressure in chamber 73 to flex diaphragm 80, thus unseating valve 86, to cause an increase in pressure in chamber 77 balancing the pressure on either side of diaphragm 80. A pressure indicating instrument is connected via conduit 78 to chamber 77, thus in effect indicating the pressure across diaphragm 21. Amplification is provided by connecting chamber 75, via port 91, valve 55, conduits 51, 151, 91, to chamber 52 on the high-pressure side of diaphragm 53. Thereby assisting movement of shaft 36 to further restrict nozzle 37 and thus increase the pressure in chambers 73 and thus 77.

Title: Improvement in fire warning systems
IPC: A62C3/08
Filed: 1966-08-08
Abstract: 1,148,952. Fire alarms. EMCO SYSTEMS Inc. 8 Aug., 1966 [23 Aug., 1965], No. 35432/66. Heading G4N. In a fire warning system of the type in which an alarm is initiated by a drop in impedance between a pair of conductors separated by a heat sensitive dielectric, false alarms due to short circuit faults in the heat sensor are avoided by a circuit which detects the low impedance condition, and applies electric pulses between the conductors to remove the fault. The circuit discriminates between low impedance conditions due to (a) sensor faults, which are removed as stated above, (b) short circuits elsewhere, which actuate a fault alarm, and (c) fire conditions, which actuate a fire alarm. Sensor fault condition.-Low impedance between the inner and outer of sensor cable 10 causes a change in input to amplifier 50. The resulting change in output is rectified by unit 52, the D.C. output from which is fed via filter 54 to actuate a trigger 56. The output from the trigger 56 provides a pulse via a CR circuit 58 to actuate a relay in the unit 42, which connects a D.C. supply 40 to the sensor 10. At the termination of the pulse the relay releases. If the fault has not been cleared by the application of the D.C. supply 40, the cycle repeats until the capacitor in unit 58 is fully charged. Short circuit fault.-Should the fault not be cleared, the impedance of the cable continues to fall and the resulting rise in D.C. output from rectifier 52 actuates a trigger 64. If the low impedance is due to a fault, the rise in D.C. is rapid, and the output from the trigger circuit is fed to hold a cross coupled pair 68 in one of its states. In this state, a relay in unit 72 is released and the output from magnetic amplifier 18, due to the low impedance on line 20, actuates lamp 22. Fire condition.-If the low impedance on line 20 is due to a fire, the rise in D.C. output from detector 52 is slow. In this condition, delay circuit 74 opens gate 66 before trigger 64 operates, so that the trigger output passes through the gate to switch bi-stable 68. The relay in unit 72 now operates to connect lamp 60 to the magnetic amplifier 18. An audible alarm may be used in conjunction with the lamps. Transistorized circuits of the various units are described, Figs. 3, 3a (not shown).

Abstract: <PICT:0974994/C6-C7/1> <PICT:0974994/C6-C7/2> <PICT:0974994/C6-C7/3> A method of straightening rolled bars characterized in that during the travel of the bars upon a moving cooling bed or like conveyer the bars are subjected to a straightening tension in the direction of their longitudinal axes.  Bars fed from a hot rolling mill along a run-out roller bed having driven inclined rollers 2 are successively raised by segmented lifting elements 4, swingably mounted on a shaft 5, on to an inclined apron 7 and subsequently dropped into H-sectioned channels or tube section troughs 10 of a transversely intermittently driven chain type cooling bed conveyer 11.  At the ends of each trough gripping tongs 18 connected via draw bars 18a and rollers 20 to adjustable tracks 19 are drawn into or pushed out of wedge shaped gaps between sets of blocks 21 to engage or release the ends of the bars during the traversing motion of the troughs over the cooling bed. The bar ends are rigidly held by the grippers, which may be locked in the closed position whilst being conveyed along the cooling bed. The bars are finally released by the grippers from the underside of the conveyer on to a transversely located roller conveyer 22.  Alternatively eccentric gripping means may be used or stationary hydraulic cylinders may be provided which locate the ends of the stock in the troughs by the insertion and withdrawal of keys.
Patent GB-354985-A (GB)
Abstract: 354,985. Date calculators. SCHMID, A., 47, Schweglerstrasse, Vienna. July 23, 1930, No. 22229. [Class 106 (i).] Apparatus for ascertaining the number of days between two dates comprises two bands on each of which the days of the year are inscribed. Either band can be fed along in the direction of its length, the other band being meanwhile held immovable, the feeding movement being transmitted through gearing to a counter on which the required number of days is indicated. The bands 5, Figs. 1 and 5, have perforated edges engaged by sprocket teeth on rollers 4 rotated by handles 6. Each band is attached at its ends to drums 7 driven from the roller 4 through gearing 8, 9, 10. On the shaft of each roller 4 is a gear wheel 11 driving a pinion 12, Fig. 3, secured to a shaft 13 on which is freely mounted a gear wheel 15. The right-hand wheel 15 drives the pinion 16 of the counter 17 directly, the left-hand wheel driving the same pinion through gearing 20, 18. Slidably keyed to the shafts 13 are clutch sleeves 21, 21<1>, coupled together by a member 24 and provided on their outer faces with projections 22 and on their inner faces with projections 221. If the member 24 is moved to the left, Fig. 1, by a lever 26 having a knob 27 projecting through the casing, the projections 22 of the lower sleeve 21<1> engage corresponding recesses in the left-hand gear wheel 15 and couple that wheel to its shaft 13 so that the motion of the left-hand roller 4 is transmitted to the counter. At the same time the projections 22<1> of the upper sleeve engage recesses in a fixed partition 14 and so lock the right-hand roller. The drums 7 are connected with their driving gears 10 by frictional means comprising blocks 31, Fig. 7, which are pivoted to the wheel 10 and which are pressed on the hubs 34 of the drums by springs 32. When the drums are rotating in a clockwise direction, Fig. 9, to allow the unwinding of the strips, they are braked by blocks 37 pressing against the drum axles 28. The dates marked on the bands are viewed through windows 41, the bands being brought to rest in alignment with the window openings by wavewheels 38 with which engage spring-pressed rollers (not shown).

Title: Removing and preventing coke formation in tubular heaters
IPC: C10G9/16
Filed: 1955-12-13
Abstract: In a process for the thermal cracking of hydrocarbon oils such as heavy naphtha, kerosene or gas oil, wherein hydrocarbon vapours mixed with steam are passed through a cracking zone, e.g. a tubular furnace, deposition of carbon in the cracking zone is prevented, or carbon deposits already present are removed, by injecting small amounts of potassium carbonate into the stream of hydrocarbon flowing to the cracking zone.  The injection may be made periodically, e.g. on a monthly or bimonthly basis, in the proportion of 20-40 parts K2CO3 per million parts of oil; alternatively 5-10 p.p.m. may be continuously injected. Hydrocarbon oil is mixed, in conduit 1, with a 1 per cent aqueous solution of potassium <PICT:0786130/III/1> carbonate supplied through conduit 41.  The oil is then introduced into tubular preheater 2 which is divided into convection and radiant sections 3 and 4, the latter being heated by flames from burners 7. A mixture of hydrocarbon vapours and residual liquid, at a temperature of 600-900 DEG  F., leaves the preheater through conduit 8, and is introduced into separator drum 11, which is supplied with steam through conduit 14.  Unvaporized oil is withdrawn from the separator via conduit 12.  The vapours are taken off through conduit 13; more steam is added from conduit 15, and aqueous potash solution is injected from conduit 42. Alternatively, the potash solution may be injected by a steam-injector 46.  The vapours are passed to tubular cracking furnace 16, which is divided into a convection section 17 and a radiant section 18 heated by burners 22.  The vapours flow countercurrent to the combustion gases in section 17. Aqueous potash solution is injected through conduit 43 into the vapours at the inlets of the tubes of the radiant section wherein the vapours flow concurrently with the burner-flames and are heated up to 1200-1400 DEG  F.  The vapours are discharged from the furnace via soaking tubes 21, and are quenched with hydrocarbon liquid, added via connection 33, in conduit 32.  The quenched products are introduced into fractionating column 34, from which various fractions are withdrawn.  A portion of the liquid withdrawn through conduit 36 is used as the quenchliquid for connection 33. The tubes in preheater 2 and cracking furnace 16 may, if desired, be divided up into several banks.
