Title: Apparatus for use in processing a substance in a fluidized bed
IPC: B01J8/36
Filed: 1979-11-29
Abstract: The apparatus comprises a process vessel (11), containing a process bed (16) of fluidized particles, having a submerged entrance port (19) at one end and a submerged exit port (24) at the other end. Preferably the exit port (24) provides an exit path for particles from the process bed (16) to a second fluidized bed (41) of particles in a second vessel (40) and the entrance port (19) provides an entrance path for particles to enter the process bed (16) from the second bed (41). The bottom of the entrance port (19) is defined by a ramp (20) which slopes downwardly from a location (e.g. in the second bed (40)) outside the process vessel (11) to a sump area within the process vessel (11), the base of the sump area being defined by a first gas distributor (23). A second gas distributor (28) extends horizontally at a higher level from a side of the sump area to the vicinity of the exit port (24) and preferably a step (29) defines the side of the sump area. Vigorous fluidization of particles in the sump area removes particles from the lower end of the ramp (20) faster than they can accumulate thereby promoting a flow of particles from the entrance port (19) to the exit port (24). A similar combination of a sloping ramp (25) and distributors (43, 44) at two levels in the second vessel (40) promotes particle-circulation in one sense through both fluidized beds (16,41). A relatively low density substance (e.g. coal) added (31) to the sump area of the process bed (16) is largely retained in the process bed (16) while denser particles (e.g. CaO and CaSO4) circulate from the process bed (16) to the second bed (41) and return to the process bed (16). The second bed (41) is preferably for oxidation and heating the denser bed particles.

Title: Vehicle position fixing
IPC: G01S3/18
Filed: 1980-02-26
Abstract: In the Specification of our copending Application for Letters Patent No. 79/07,829 (Serial No. 2044033) (I/6259/M) there is described and claimed radio direction-finding apparatus for use as the heading sensor in a vehicle location system, which apparatus comprises a two-directional antenna (preferably crossed loops) coupled (alternatively) via a radio receiver to computing means which adjusts the receiver's gain such that the resultant of its two outputs is at a predetermined level, and (from the degree of adjustment and the two original antenna outputs) calculates the angle between the chosen radio source's direction and one or other of the antenna directions, so giving a relative value for the vehicle's heading. This earlier invention uses a radio source at a known bearing to provide information regarding the heading of the vehicle; it does not by itself fix the position of the vehicle. The present invention provides a vehicle position-fixing device in which, using the basic concept of the direction- finding device of the earlier invention, but with receiving means which is tuneable to the frequency of any one of a number of possible radio sources of known position, additional computing means are employed to produce as outputs (i) a signal which may be used to tune the direction-finding device to the frequency of a chosen radio source, and (ii), after operating upon the directional data obtained in respect of at least three chosen radio sources, a signal corresponding to the position of the vehicle.
