Title: Improvements relating to tubulous vapour generating and superheating units and to the operation thereof
Inventor: BEUTHNER FRIEDRICH
IPC: F22G3/00
Filed: 1953-11-09
Abstract: 750,257. Steam superheaters. BABCOCK & WILCOX, Ltd. Nov. 9, 1954 [Nov. 9, 1953]. No. 30929/53. Class 123(3). In a water-tube boiler having a horizontal pass 4 from which furnace gas flows downwardly through a vertical pass 2 in which is disposed a superheater 42, the tubes 44 of the latter are supported by brackets 48, 50 welded to spaced tubes 10 lining the refractory front wall 6 of the downpass and brackets 52, 54 welded to tubes 12 lining the rear wall 8 thereof, the tubes 10, 12 conveying steam from an upper header 14 receiving saturated steam from the steam and water drum of the unit to a lower header 18 whence the partly superheated steam flows through superheater 42 to an outlet header 38. When the boiler is shut down, to prevent overheating of tubes 10, 12 by heat transference from the walls which they line to temperatures at which they are insufficiently strong to support the weight of the superheater, means are provided for maintaining a cooling flow of steam from the steam and water drum through the tubes until the danger of overheating is past. For this purpose header 18 is connected by a pipe 61 to a blow-down, or heat conservation tank 60, the pipe 61 having a valve 62 which is urged towards the open position by a spring 106, the valve being closed manually before starting up and held closed during normal operation by the engagement of a latch 124 with a projection 126 on the valve spindle. The withdrawal of latch 124 and consequent opening of valve 62 to establish the cooling steam flow is effected in response to the reduction in pressure drop across the lining tubes and superheater 42 to a predetermined point, the tube inlet header 14 and the superheater outlet header 38 being respectively connected by pipes 68, 70 to pressure responsive elements 64, 66 which act through pneumatic pilot valves 72, 74 to transmit control pressures through pipes 721, 741 to opposite sides of a diaphragm 82 of a differential relay 76. When, during the shutting down of the unit, the pressure drop reaches the predetermined low level, a contact 98 on a rod 100 attached to diaphragm 82 moves into contact with a fixed contact 96 under the action of a diaphragm spring 84. A circuit is thus established from a battery 88 through a solenoid 94, the solenoid plunger 118 withdrawing the latch 124 against the pressure of a spring 116, the spring 106 then opening the valve 62. To avoid unnecessary discharge of steam from the steam and water drum into tank 60 a switch 92 is opened when the danger of overheating of tubes 10, 12 is past and valve 62 closed by manual operation of a rack and pinion 120, 122. On restarting the switch 92 is closed after the superheater pressure drop has risen sufficiently to open contacts 96, 98.

Title: Improvements relating to feed control in the drilling of wells
IPC: E21B19/08
Filed: 1955-11-04
Abstract: 776,132. Automatic borehole drilling. NATIONAL SUPPLY CO., and OIL WELL ENGINEERING CO., Ltd. Nov. 4, 1955 [Dec. 20, 1954], No. 31553/55. Class 85 [Also in Group XXIX] An automatic feed for a rotary drill string comprises a spooling drum 10 on which is wound a cable 11 feeding a travelling block 20 which supports the drill string, a brake 14 being forced into the drum 10 by a spring 23 and released by a piston 24 subject to fluid pressure which is controlled by the tension in the cable 11. In one embodiment, Fig. 1, fluid is drawn from a reservoir 47 through a conduit 48 to a pump 46 and then passes through a conduit 49, including valves 51, 50, to operate a motor 38, the discharged fluid passing through a conduit 103 and a conduit 28 to a stuffing box 29 and then out through ports 39 in arms 32, which are rotated by the drum shaft 43, of a follow-up valve 33, the fluid then passing through conduit 107 back to the reservoir 47. The motor 38 rotates a follow-up member 31 of the valve 33. The valve 50 is actuated automatically in dependence upon the tension in the cable 11 through a fluid capsule 22, a Bourdon tube operated valve 54 and a compressed air circuit 64,. 52 acting on a diaphragm 68 so that the valve 50 throttles the fluid flow through the conduit 49 on a decrease in the tension in the cable 11 when the valve 51, maintaining a constant pressure drop across the valve 50, will by-pass some of the fluid flowing through conduit 49 to a conduit 101 which communicates at one end with the conduit 28 and at the other, through a relief valve 102, with the reservoir 47. When the tension in the cable 11 increases the valve 50 tends to open giving an increased supply to the motor 38 increasing the speed of rotation of the member 31 which tends to close the ports 30 in the member 32. This causes an increase of pressure in the conduit 28, a branch of which communicates with a piston 24 which acts against the spring 23 and tends to release the brake 14 with a consequential increase in the speed of rotation of the drum 10. In one modification the rotary follow-up valve 33 is replaced by a needle valve operated by changes in the relative speed of rotation between the motor 38 and the drum shaft 43. A separate pump may be used to supply fluid to the valve 33 and the piston 24. The follow-up valve 33 may be replaced by a differential gear assembly. Specifications 600,294, 720,445 [Group XXIX] and U.S.A. Specification 2,650,796 are referred to.
