Abstract: 1,098,521. Controlling conveyer drives. COAL INDUSTRY (PATENTS) Ltd. Nov. 27, 1964 [Aug. 30, 1963], No. 34411/63. Heading B8A. [Also in Division H4] In a system for controlling from a first position apparatus located at a second position remote from the first position, comprising a first high-frequency transmitter and a first receiver at the first position, a second receiver at the second position responsive to signals transmitted from the first transmitter and adapted to control the operation of the apparatus and the operation of a second highfrequency transmitter at the second position, the second transmitter is adapted to transmit further signals to the first receiver, and a wire capable of carrying high-frequencysignals is inductively coupled with both transmitters and receivers. The invention is described in relation to a conveyer arranged at a mine face which is driven by a motor 6, 7 at each end thereof. A " start " button is operated at the head end of the conveyer and the driving motor at this end is energized together with a transmitter supplying a 50 kc/s. carrier modulated with a 660 c/s. signal. The transmitter is coupled inductively to an insulated wire 12 which may be disposed in the waste in front of the coal-face and the receiver at the tail end of the conveyer is likewise coupled to the wire and operates a relay to start the motor 6 at the tail end. Reception of a signal at the tail end also starts the transmitter at this end and a 70 kc/s. carrier modulated by a 900 c/s. signal is returned via the cable to the head end, reception of this signal locking the " initiating " circuit in the operating position. A timing circuit ensures that the control means at the head end are tripped out if the return signal is not received. Further modulating frequencies may be used in each direction to allow the remote control of other functions.

Operation.-The device is clamped to the hub 2 and with the motor 9 switched off, the propeller is accelerated to operation speed. The disc 4 rotates with ring 1 due to the reduction gearing in drive 5 and the unbalanced weight 4 causes vibrations of a fixed amplitude which are detected, e.g. with an oscillograph. Motor 9 is now started so that disc 3, with weight 4, slowly rotates around ring 1 changing the amplitude of vibration until a minimum is found at which point motor 9 is switched off and the propeller is stopped. The final position of test weight 4 shows where the balancing weight is to be attached after removal of the device.

Title: Improvements in or relating to fluidized solid reactions
IPC: B01J8/10
Filed: 1956-11-20
Abstract: In a method for treating finely divided material, including catalysts having a kieselguhr basis, with gases in a fluidized bed reactor, the fluidizing gas is wholly or partly introduced into the material through the blades of stirrers.  Coal dust having a particle size of 60 microns and below is treated with air in a fluidized bed reactor so that from 6-30 per cent of oxygen is combined with the coal.  A stirrer is located as near to the bottom of the reactor as possible, the whole of the fluidizing gas being introduced downwardly from the stirrer blades.  In a modification several stirrers are arranged in superposition. The gas outlet openings in the blades are such that there is a uniform distribution over the reactor cross-section, the number of openings or their diameter being thus correspondingly greater at the ends of the stirrer blades than in the vicinity of the axis. The stirrer, which may consist of tubes of round or elliptical cross-section, may rotate about a vertical or a horizontal axis or perform a pendulum movement.
