Title: Improvements in or relating to the distillation of oil bearing minerals

IPC: C10G1/02
Filed: 1951-04-16
Abstract: 711,426. Distilling oil shale. STANDARD OIL DEVELOPMENT CO. April 16, 1951, No. 8873/51. Class 55 (1) In a process for distilling oil shale, particulate shale as a fluidized mass is heated by indirect heat exchange with a-fluidized mass of burning or burned spent shale. As shown in Fig. 1 raw shale is fed from a hopper 1 to a header 25 arranged with a vessel 10 and communicating with tubes 20 which extend through the vessel 10 and are surrounded by a fluidized bed of burning spent shale confined within the vessel 10, fluidizing gas, for example, steam or tail gas, is introduced into the tubes 20 by nozzles 23 and the shale is distilled as a fluidized bed formed within the tubes 20 and the header 25. The shale is heated to between 800-1400‹ F. in its passage down the tubes, distillation vapours and gases leave through line 29 or through line 7 to preheat the incoming raw shale in the hopper 1. Spent shale from the bottom of the tubes 20 passes into a hopper 30 and then through a valve 34 into a line 36 where it is entrained by air entering the line 36 and conveyed to the vessel 10 and into the fluidized bed of burning shale around the pipes 20. Combustion gases leave by line 38 and coarse particles of spent shale are withdrawn through line 40. The amount of oxygen in the air supply is controlled to give the mass of burning spent shale a temperature of between 1100-1600‹ F. and the rate of withdrawal of the spent shale from the hopper is controlled by the valve 34 to give the shale in the tubes 20 a distillation period of 2-10 minutes. In a modification the zone in which the spent shale is combusted may be subdivided by a number of horizontal perforated partitions and the liquid products of the distillation may be withdrawn from a middle portion of the tubes 20. In further modifications, the spent shale is combusted in a burner arranged below a distillation vessel and hot burned spent shale is passed upwardly suspended in the combustion gases through tubes passing through the distillation vessel and surrounded by a fluidized bed of shale undergoing distillation. The distillation vessel may have horizontal perforated partitions and spent shale is fed from the bottom of the vessel to the burner. Spent shale may be separated from the combustion gases after passing through the tubes in the distillation vessel and be returned to the burner. Specification 644,013 is referred to.

[Class 40 (i)] [Also in Group XXXVII] The level of a liquid under pressure is indicated with the aid of one or more condensers arranged in a strong side tube to which the liquid which serves as the dielectric is admitted. In one arrangement, Fig. 1 (not shown), separate condensers are arranged at different levels in a number of projections D<SP>1</SP> from the side tube D. The initial position of the condensers may be adjusted by means of a screw H. They may be included in separate tuned circuits associated with relays or may be connected in a common circuit. In another arrangement, Fig. 3, a number of relays L are included in the circuit of the condenser formed by the wall of the side tube and an adjustable tube. These relays are operated by the joint effect of the increase of current due to the increased capacity and of a magnet K floating on the liquid. The change in current in the relay circuit may be separately indicated. The magnet may be in a separate tube.

Abstract: 895,113. Control of motors. ENGLISH ELECTRIC CO. Ltd. March 23, 1959 [March 21, 1958], No. 9229/58. Class 38 (3). [Also in Group XXXV] In a motor control system, a primary reference signal, selected by a control-member, is amplified to form a secondary reference signal and the rate of change of the secondary signal is limited by feed-back responsive to said rate of change varying the energization of the amplifier. As shown, a control lever 17 moves a slider 16a of a potentiometer 16 to derive a primary reference signal, representative of the desired direction and speed of rotation of a motor, not shown, which is fed to an input winding 13a of a magnetic amplifier 13. A secondary reference signal from the amplifier is opposed by the output of a tachogenerator 12 coupled to the motor and the resultant control signal through change-over contacts 15a, 15b is fed to a negative error suppressing device 11. Positive-going signals are fed to a control winding 10a of a torque controller 10 for the motor. A change-over device 14, actuated in dependence on the sense of the control signal, conditions the motor for driving or braking mode of operation. The changeover contacts 15a, 15b are actuated by a device, not shown, responsive to whether the motor is motoring or braking. The secondary reference signal is fed through a differentiating circuit 19a, 19b to a feed-back amplifier 18. The output of the amplifier 18 energizes a control winding 13b, through a rectifier 22 or 23, when the rate of change of signal exceeds a predetermined positive or negative value set by a slider of a potentiometer 20. A separately-excited D.C. motor is controlled by having the armature supplied through a grid-controlled current converter, the grid-phase of which is varied by the torque controller as disclosed in Specification 892,231. A wound rotor A.C. induction motor is controlled by varying the rotor resistance by the torque controller and during braking operation connecting the stator to a D.C. supply or low-frequency A.C. supply. The system may be modified by leaving out the biasing arrangement for the control winding 13b.

Filed: 1921-03-29
Abstract: 180,138. Gowan, S., Brooks, R., and Metropolitan-Vickers Electrical Co., Ltd. March 29, 1921. Automatic starters of the segmental resistance contactor type comprise a current limit relay provided with two windings 2. 3 which are either oppositely wound on a single limbed magnet as shown in Fig. 1, or are wound on separate limbs as in Fig. 2, the effect in each case being that when both windings are energized contacts 9, 10 remain closed. Excessive current in the motor circuit flowing through a series coil 8 cuts out the winding 2 and separates the contacts 9, 10, which are connected in the actuating circuits of all the resistance contactors, thereby suspending the starting sequence. To prevent disturbance of the contactors which have already operated, each contactor, in closing, connects its coil in a circuit independent of the limit relay. Economy resistances may be placed in the control circuits.
