Title: Improvements in or relating to gas turbine plants
IPC: F02C7/141
Filed: 1946-07-05
Abstract: 614,106. Fluid-pressure servomotor-control systems. SULZER FRERES SOC. ANON. July 5, 1946, No. 20198. Convention date, July 19, 1945. [Class 135] [Also in Group XXVI] The two stage air-compressor of a gas-turbine plant has interstage cooling by water injection which is automatically varied to maintain a delivery temperature so related to the inlet temperature and the delivery pressure that the air beyond the point where the water is introduced is substantially saturated. A temperature-responsive device 26 in the compressor outlet 7 is connected to a pressure-fluid control valve 39 through a spring 30 so that the pressure of the fluid below the valve, being balanced by the pressure of the spring, is a measure of the temperature in the delivery. This pressure is applied above a spring-loaded piston 43 connected to a beam 44 of a servo-motor 45, 46 which through a beam 47 controls the water injection valve 48. The follow-up connection between the piston 46 and the beam 44 includes a piston 50 in a cylinder 51 having an end-to-end leak 53. The pressure of a spring 52 is varied as the inlet temperature and the delivery pressure vary and the piston 50 moves correspondingly in its cylinder 51. This alters the length of the follow-up connection and, correspondingly, the temperature associated with the normal position of the servomotor. A temperature-responsive device 27, in the compressor inlet 2, operates through a spring 31, a valve 40 and a spring-loaded piston 55 to move axially a shaft 57 in correspondence with variations of inlet temperature. A pressureresponsive device 28 operates similarly to rotate the shaft 57 by gear 60, 61 in correspondence with variations of delivery pressure. These two movements are compounded by means of a snail cam 63 of a throw which increases from right to left, and a plunger 64 connected to the spring 52. Variations in the inlet temperature and delivery pressure also influence the water valve 48 directly by means of a similar but reversed snail cam 65 and a plunger 66 which is connected to a servomotor 75, 77 controlling the opposite end of the beam 47.

Title: Well logging data processing methods
IPC: G01V11/00
Filed: 1971-04-19
Abstract: 1344194 Borehole logging SCHLUMBERGER INLAND SERVICES Inc 19 April 1971 [2 Feb 1970] 20713/71 Heading G1N The invention relates to the processing of borehole logging data. Logs are made with standard "logging tools" of:- Deep and Shallow Resistivity, (which is dependent mainly on distribution of fluids in the formation pores). Spontaneous Potential (which is different in shale and sand). Gamma Ray Transmission (dependent on electron density which is proportional to bulk density of adjacent layers). Neutron Log (representative of hydrogen in water or oil in pores, i.e. porosity of layer). Sonic Travel Time (dependent on nature and porosity of rock). Data from a number of runs may be recorded and combined on a single tape. Interpretation of the logs is firstly dependent on the fact that gamma-ray and neutron logs are not affected by shale whereas the other logs are affected. This is illustrated in Fig. 11, by a cross-plot of density-derived porosity # D  versus neutron-derived porosity # N , the effect on a plotted point of various types of shale relative to the "clean-sand-line" is indicated. The shale line represents substantially zero porosity but includes a certain amount of water associated with the clay. The effect on the plot of the proportion of shale V sh  and the porosity # D  can be represented by lines parallel to the sand and shale lines respectively Fig. 3 (not shown). Thus if the volume of shale is determined from other logs, the plotted point can be shifted parallel to the shale line by this amount e. g. as illustrated in Fig.15 (not shown), and if the point then lies above the clean sand line the presence of hydrocarbons may be indicated. The shale indicator is then re-checked and cross-checked several times, with parameters computed from the other logs. Equations for mathematically performing the above technique (together with corrections to be applied to the logging data and cross-checking parameters). The calculated values of V sh  are arranged so that they will be equal to or greater than the true V sh , thus the nearest-correct value will always be the smallest computed value. Flow diagrams are given Figs. 19A..24B (not shown) for preparing programs to carry out the above analysis in a digital computer. These diagrams list the equations according to reference numbers in the description and indicate when checks are to be made in "decision elements" and the data discarded or recycled and corrected. A final stage prepares data for print out.

Abstract: 584,343. Door-operating gear. MARRYAT & SCOTT, Ltd., and HONEY. L. W. Oct. 30, 1944, No. 21191. [Class 65 (i)] [Also in Group XXX] An arrangement for closing a lift cage or landing gate comprises a power-operated endless chain and coupling means between the gate and the chain whereby the chain when driven will close the gate, but will, at all times, permit manual opening and closing of the gate. A bracket 14 is mounted on the second picket 2 from the opening end of the gate and carries a pivoted dog 16 which is pressed upwards by a spring 17 into the path of nibs 13 mounted on an endless chain 12. This chain is passed round an idler sprocket 10 and a driving sprocket 9. The latter sprocket is driven by a motor 6 mounted on the cage roof and has a free-wheel device. The bracket 14 carries a ramp 23 and an adjustably mounted roller 26. The ramp engages a roller on the end of a pivoted arm 22 to actuate the usual interlocking contacts which prevent the lift motor from being started unless the gate is closed. The roller 26 engages a piyoted arm 24 which actuates contacts in the circuit of the motor 6 to switch it off just as the gate is closed. A tail piece 29 is provided on this arm to cause the closing of the contacts when the gate is opened. If the motor 6 fails, the gate can be operated by hand since the dog 16 will override the nib 13 during opening by compression of the spring 17, and during closing the gate will carry the nib out of the path of the dog by the action of the free-wheel device. A time switch actuated by the arm 24 may delay the starting-up of the motor 6 until a suitable interval has elapsed.
