Title: Method and apparatus for cooling and de-dusting hot particulate material
IPC: B01D49/02
Filed: 1974-06-11
Abstract: 1454328 Cooling materials discharged from furnaces GREAT LAKES CARBON CORP 11 June 1974 [28 June 1973] 25926/74 Heading F4B Hot, particulate material, e.g. petroleum coke, is cooled in a long, rotating, slightly inclined cylinder 1, having nozzles A for spraying water on the coke in the entry portion and a further cooling section where the outside of the cylinder is cooled by a water dip 6 and internal air is provided through pipes 8. Section 10 is divided into four compartments cooling the coke by tumbling. The temperature of the coke is measured at at least one location by thermocouples placed and connected through a central, non-rotating conduit 14 supported by a rotating hub of the cylinder, the thermocouples serving to control the supply of water to further sprays in different portions of the cylinder to ensure the coke leaving at Z shall not be above a given temperature. The dust associated with the coke is suppressed by oil spraying at 20 and the coke tumbled in the six compartments of section 11 for mixing the oil and coke. Conduit 14 houses pipes carrying water from supply pipe 46 to spray nozzles 24 and 26, as well as thermocouple lines to measuring points 25 and 27, and a pipe (18), Fig. 5 (not shown), carrying oil from supply pipe 35 to the oil spray manifold 20 (details, Fig. 4, not shown). The thermo-couple measuring point 27 regulates supply of water to main spray nozzles A and can cut in additional water supply from line B and spray nozzle 26 if the temperature of the particulate material rises above the desired level. The thermocouple measuring point 25 controls operation of a solenoid valve supplying water to spray 24 24 and also a shut down valve to oil pump 38 and shut down of the motor for driving the cylinder 1 if temperature in this area reaches a dangerous level. A further thermocouple 33 in the shoot to the conveyer controls a supply of spray water to the end of the cooler if the temperature in this area gets beyond acceptable limits and can shut down the cooler and oil supply pump if limits are exceeded. A baffle 7 deflects material as it enters the oil injection zone to prevent clogging of the oil sprayer. Diverter plates 55 assure an equal division of material to the six compartments in section 11. Hinged openings 31, 32 give access to the interior of the cooler when required. Structural designs of sections 10 and 11 can be varied to change the number and shape of the compartments, Figs. 7, 8 and 9 (not shown). In a simplified version of the apparatus, Fig. 11 (not shown) the cooling air pipes 8 and the free fall tumbling zone of section 10 in Fig. 1 are omitted. In a further, even more simplified version, Fig. 12 (not shown) the free fall tumbling zones of sections 10 and 11 of Fig. 1 are omitted as well as the oil sprays.

[Also in Group XXXVI] In a T.R. device having a transverse metal wall containing a window constituted by a resonant slot hermetically sealed by glass, the window is protected by an enclosure of vitreous, ceramic or like insulating material of a refractory nature, e.g. glass or synthetic mica, which is joined directly or indirectly to the metal wall at regions displaced on each side of, and preferably mainly parallel to, the longer dimension of the slot, the material of the enclosure joining with the glass sealing the window and forming an unsealed enclosure over the window. The T.B. cell shown comprises a section 9 of rectangular waveguide closed at one end by a metal wall 1 containing a sealed aperture 2 covered by a glass dome 4 which is perforated by two holes 10. An evacuating and filling tubulation 12 passes through a mounting flange 11. A flexible metal diaphragm 13 secured to the broad walls of the waveguide e.g. by brazing, is provided with a bar 14 having a threaded bore to enable the position of the diaphragm to be adjusted for tuning purposes by means of a threaded rod introduced temporarily through the tubulation 12 before it is sealed off. A suggested filling consists of water vapour at 4.5 mm. pressure or less, added to a rare gas such as argon or kryton at 10 mm. pressure. The window may be sealed and the dome 4 provided in one operation by the method described in Specification 833,886. Alternative methods of forming the protective enclosure are described with reference to Figs. 1 to 4 (not shown). The enclosure prevents the products produced by the discharge across the slot from interacting with metal, particularly in the vicinity of the slot.

Title: Improvements in and relating to pulse modulation radio transmission systems
IPC: H04B7/17
Filed: 1965-06-23
Abstract: 1,075,386. Pulse signalling. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. June 23, 1965 [June 26, 1964], No. 26582/65. Heading H4L. In a pulse communication system of the random-access discrete-address type, at the transmitter, Fig. 1, the output of an oscillator 1 is converted into pulses at 2 which are positionmodulated by the signal from 10 and supplied to a tapped delay line 3. The oscillator 1 also controls a counter 4 which opens gates 5, 6, 7, 8 in that order, these gates being connected to the taps on the delay line in a sequence which is determined by the address of the station being called. The outputs of the gates control a trigger 9 which supplies narrow pulses, coded in groups of four in accordance with the required address, to amplitude modulate a carrier at 12. The frequency of the oscillator 1 may be adjustable to select any one of a plurality of predetermined frequencies to provide a larger number of addresses. The pulse signals may be amplitude-modulated instead of position-modulated. Receiver, Fig. 2.-Circuit elements 1 to 8 are the same as those at the transmitter, the tappings on the delay line 3 being connected to the gates 5 to 8 in accordance with the receiver address. The outputs of the gates are applied via a limiter 14 to a receiver gate 15 which is released on receiving the correct address signal so that the incoming pulses are detected at 16 and applied to a phase discriminator 17. The phase discriminator receives a reference signal consisting of the outputs of gates 5 to 8 differentiated at 18, and the output of the discriminator is integrated at 19 and applied via control circuit 20 to synchronize the oscillator 1, and is also supplied via amplifier 21 and gate 22 to reproducer 23. The output of the detector 16 is supplied to a peak detector 24 with a time constant such that when one or more address pulses are lacking the detected voltage falls' below a reference voltage in a threshold device 25. This operates a multivibrator 27 which supplies a signal to the control circuit 20 to disturb the synchronization of oscillator 1. so that reception is not possible. A further detector 28 is operated by the multivibrator 27 to supply a voltage to cut off the gate 22 until synchronization is restored.
