Title: Improvements in or relating to the salvaging of heat of combustion in oil field equipment
Inventor: COGGINS ROBERT WAYNE
IPC: C10G9/20
Filed: 1968-03-01
Abstract: 1,221,661. Separating liquids, dehydrating glycol. COMBUSTION ENG. Inc. 1 March, 1968, No. 10173/68. Headings BIB, B1D and B1X. Separating apparatus for use in oil fields, for separating oil and water mixtures produced by the oil well (Fig. 1) or for separating glycol, used for drying natural gas, from absorbed water (Figs. 2 to 5, not shown), comprises a vessel 1 heated by combustion gases from burner 3, which pass through tube 2 and up stack 4, and a heat exchanger 14 through which liquid under treatment is recirculated to conserve combustion heat and reduce the temperature of gas leaving the stack to a safe level. In Fig. 1, vessel 1 acts as as a settling tank, from which water, oil or emulsion and gas are discharged at different levels. Separation is assisted by the heating, and an optimum mixture of oil and water is determined by one or two valves 11 and pumped through the heat exchanger at a rate controlled by valve 13, whose setting is varied by temperature sensor 20, to join the incoming well product at 5. In Figs. 2 to 5, glycol and water from a gas drying stage are separated by boiling off the waiter in vessel (30), from which the glycol is returned to the drying stage through ballast tank (37). The drawings illustrate the different routes and take-off/return points for the glycol which is recirculated through heat exchanger (34).

Title: Improvements relating to the counting of electrical impulses
IPC: H03K23/74
Filed: 1936-04-09
Abstract: 471,987. Electric signalling systems. SIEMENS BROS. & CO., Ltd., and HUMPHRIES, H. E. April 9, 1936, No. 10536. [Class 40 (i)] [Also in Group XXXIX] In a relay counting chain, the operation of each relay in the chain first sends back a signal to the impulsing point to terminate the impulse which operated it and then connects up the next relay in the chain. As shown, impulses are generated under the control of a self-interrupting relay L. On the operation of L, a normally-charged condenser Q and battery over a resistance Z are connected in parallel to effect the rapid operation, during the " make-through " period of contacts l1, of a high-speed relay X which then connects itself to the pulse wire P in series with the first relay A of the counting chain. Relay A operates first its locking contact a1, which short-circuits relay X to terminate the pulse, and then its other contacts, switching over the pulse lead to relay B. Relay B similarly operates at the next connection of X to the pulse wire and after terminating the pulse switches in C and at contacts b4 connects in a reverse winding of A so that A releases when the flux becomes zero. The chain operates similarly for succeeding pulses, relay D remaining locked after the fourth, relay C after the seventh, and relay B after the ninth. Alternatively to the short-circuiting action of contacts such as a1, the change-over period of contacts such as a2 may be used to release X to terminate the pulse. Contacts of relays A .. D arranged in " tree " formation may be used to light lamps.

Filed: 1960-03-25
Abstract: 902,856. Cooling gases by direct contact with liquids. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 20, 1961 [March 25, 1960], No. 10702/60. Class 64 (1). [Also in Group XII] In apparatus for preparing substantially oxygen-free, water-cooled gases for use, for example, in metallurgical processes, the hot combustion gases are initially cooled in a cooling chamber by direct contact with water and then passed through a second cooling stage comprising heat-exchange surfaces arranged inside the chamber wherein water vapour is condensed, the condensate being returned for use in the initial cooling stage. In the form shown in Fig. 1 the apparatus consists of a combustion chamber in which a fuel containing hydrocarbons and/or hydrogen, for example, gases such as town gas, propane or acetylene or liquids such as ethyl alcohol, benzene, toluene, petrol or fuel oil, is burnt without an appreciable excess of air, the combustion products being injected downwardly into a mass of water in a sump. Non-condensable gases and water vapour flow upwardly from the sump past a heat-exchange coil, water vapour being condensed and returning to the sump whilst the cool product gas discharges from the top of the heat-exchanger column. In a modification, Fig. 2 (not shown), water is sprayed into the hot combustion gases, a pump supplying the sprays with condensate from a sump arranged below the heat-exchanger column.

Title: Process and apparatus for collecting and stacking of flexible sheets
Inventor: STOBB ANTON RUDOLPH
IPC: B65H29/14
Filed: 1957-04-02
Abstract: 809,212. Sheet - delivery apparatus. WESTERN PRINTING & LITHOGRAPHING CO. April 2, 1957, No. 10716/57. Class 100(1) A collector of flexible sheets disposed in overlapped relation on a conveyer which moves them in a stream to a receiver is characterized in that the conveyer includes endless belts which are movable across the entire entrance to the receiver in an upward direction, the sheets are disposed between the belts and the receiver, so that the belts press the sheets against the end of a stack in the receiver, and a stop is provided in the path of the sheets for stripping them from the conveyer. As shown the sheets 11 are delivered in overlapped fashion by an endless conveyer 10 trained around pulleys 13, 14, 15, 16 and 37 which co-operate with a second endless conveyer 34 trained around pulleys 36, 37 and 38. The sheets are stacked on the table 31 of a receiver 24, an endless belt 27 being provided for forwarding the sheets along the table as they are stacked. The sheets are stripped from the conveyer 34 by a stop plate 26, supported for vertical movement on posts 29. Delivery of the sheets to the stack is assisted by grooved rollers 32 mounted on the same shaft as the pulleys 16 which receive the trailing edges of the sheets and bend them away from the receiver entrance. The conveyer 34 comprises four endless bands, four pulleys 36 and four pulleys 38. The pulleys 36 are mounted on a shaft 42 supported by rods 39 extending from the machine frame 18. The two outer pulleys 38 are axially offset with respect to the two centre pulleys 38 so that the sheets on delivery to the stack are arcuately curved at their leading edges. The pulleys 38 are mounted on a shaft 43 anchored in side plate 35 of the machine frame. Four brackets 44 are spaced along the shaft 43 and each supports a rod 46. The upper end of the rods 46 support forks 47 which rotatably support the pulleys. The brackets 44 are adjustably clamped to the shaft 43 by bolts 49.

Title: Auxiliary recording arrangement for automatic telephones
IPC: H04M1/56
Filed: 1935-04-08
Abstract: 439,015. Automatic exchange systems. BRODER, H., 21, Storchengasse, Zurich, Switzerland. April 8, 1935, No. 10834. Convention date, April 7, 1934. [Class 40 (iv)] Apparatus is provided at the substation for printing in respect of each call made the dialled number, the charge, and the time the call is ended, on two strips, one of which is delivered to the subscriber as a check while the other serves as a record. The type wheels are set electromagnetically by the dialled impulses and by metering impulses from the exchange. Upon lifting of the receiver, the supply transformer 5 is connected over switch-hook contact 2 to magnet 3 which attracts its armature 6 until it strikes a stop 7, thereby closing contact 8, which completes a parallel circuit through magnets 11, 12 in shunt with the normal contact 10 of the dial 13. The driving pawls 21 of the number wheels 23 engage notches in a shaft 19 so arranged that as the shaft is stepped round the pawls are brought into engagement with their ratchet wheels in turn. All the pawls are controlled by a single magnet 31 which is in turn controlled by a relay 28 in the impulse circuit. Each operation of the dial allows magnet 12 to energize and step the shaft 19. The first energization of magnet 11 withdraws the stop 7 and allows the armature 6 to complete its movement. At the end of the conversation, A.C. metering impulses from the exchange are received by relay 36 and are repeated at contact 39 to magnet 41, contact 8 being still closed, to advance the charge printing wheels. Magnet 3 is held after the replacement of the receiver by the intermittent closing of contact 50. When all the impulses have been received, the armature 6 of magnet 4 returns slowly under the control of a flywheel 33 and by means of a pawl 51 closes contact 53 momentarily to energize magnet 54, which releases a disc 59 and allows it to be driven through one revolution by a motor 58 until a catch 60 falls into locking position again. During this period, the motor drives in turn three Geneva wheels, the first bring- ing about a lowering of a roller 71, Fig. 2 to print the record on the strips 62, 67, the second feeding these strips and the ink band 64 and the third operating a blade 74 to sever the printed ticket from the strip 62. The time and date are printed by wheels 82, 83. In order to prevent a fresh connection being made before the printing operation is completed, the armature 6 of magnet 3 during its retarded return movement drives a notched disc 78 through one revolution during which contacts 48, 49 are opened in the line circuit, while contact 79 opens the circuit of magnet 3 independently of contact 2. Contacts 48, 49 are held open also by relay 46 which is connected in series with the motor 58. The printing operation may also be brought about by means of a press button 84, the contacts 85 connecting up the magnet 54.

Title: Improvements in the generation of steam power
IPC: F22D1/32
Filed: 1958-04-03
Abstract: 839,669. Power-generating systems. FOSTER WHEELER Ltd. April 3, 1958 [April 8, 1957], No. 10924/58. Class 122 (3). [Also in Group XIII] A steam power plant comprises a once through boiler 20 operating at supercritical pressure, an independently fired superheaterreheater chamber 39 and a three-stage turbine 43 driving an electric generator 44. There are two operating circuits. In the first water is drawn from a steam and water vessel 13 by a pump 15 and delivered to the tubing 19 of the boiler 20 at supercritical pressure. In the boiler it is heated to above critical temperature and leaves through a line 22 to a turbine 26 driving the pump 15 and a turbine 27 on the shaft of the main turbine 43. Superheated steam exhausts from the turbines 26, 27 into the vessel 13 wherein it heats feed water to generate saturated steam forming the working fluid of the second circuit. In the second circuit the steam from the vessel 13 passes through a superheater 37 in the chamber 39 to the high-pressure stage 42 of the turbine 43. The exhaust is reheated at 38 and flows through the subsequent turbine stages 46, 49 to a condenser 50. Condensate is withdrawn by a pump 52 and returned to the vessel 13 through a series of bled steam heaters 53 ... 55, 63 ... 65. During full load operation the burners 21, 40 of the boiler 20 and superheater-reheater chamber 39 respectively are fired so as to provide for equal absorption of heat by the elements 19 and 37, 38 and the whole of the steam exhausting from the turbines 26, 27 flows into the vessel 13. At less than full load a valve 33 in a by-pass 32 opens to allow some of the superheated steam to bypass the vessel 13 and flow directly to the superheater 37 in admixture with the saturated steam from the vessel 13. Under these conditions the heat required from the burners 40 is much reduced and their firing rate is decreased whilst that of the burners 21 is kept at a high level. Specifications 761,617 and 805,257 are referred to.

Title: Process for the recovery of values from phosphate rock
IPC: C01F17/265
Filed: 1955-04-18
Abstract: A fertilizer containing dicalcium phosphate is obtained from phosphate rock containing rare earth compounds and fluorine compounds by reacting with 14-62 per cent sulphuric acid to obtain a solution containing monocalcium phosphate, fluorine and rare earth compounds, separating the precipitated calcium sulphate, adding calcium carbonate or lime before or after heating to 85 DEG C, to give a P2O5; Ca weight ratio of 10 : 1 to 4 : 1, allowing the solution to stand, if necessary, to insolubilize a fluorine-rare earth compound, separating said compound, if desired, and adding a further quantity of calcium carbonate or lime to precipitate dicalcium phosphate. Preferably hydrated or another form of reactive silica is arranged to be present during the acid treatment: it is then not necessary for the solution to stand to precipitate the fluorine compound.  If necessary due to deficiency in the phosphate rock, a rare earth containing ore such as monazite may be added prior to acidulation or a rare earth compound in solution may be added during or after acidulation, a sulphate, e.g., calcium sulphate may be added to the solution from which the fluorine compound is precipitated and sufficient calcium and aluminium to effect complete removal of the fluorine compound should also be present.  In the acidulation, preferably 80 per cent of the sulphuric acid necessary to convert the P2O5 content of the rock to H3PO4 is used. In an example details are given of a process using silica and pH and other conditions are specified.  The fluorine-rare earth compound which may be present in the product may contain F, Ca, p  SO4, Al, Si, Sr, water and rare earths; e.g., La and Y, and when monazite is added (v.s.) Ce and Yb may also be present: Zr has also been observed.  U.S.A. Specifications 1,809,473, 2,013,970, and 2,164,627 are referred to.
