Patent ZA-874800-B (ZA)
Title: A centrally controlled telecommunications exchange
Inventor: JUNGE UWE
IPC: H04Q11/04
Filed: 1987-07-02
Abstract: The line trunk groups, which are connected to the doubled switching network via two time-division multiplex lines each and exhibit, among other things, one group switch each and one local group processor each are associated with one another in pairs. In preparation for a switching to standby of the central switching network and associated central processor, the subscriber lines and/or junction lines of the two line trunk groups in each case associated with one another in pairs which are connected to a first one of these two line trunk groups can be switched from the group switch of the first line trunk group to that of the partner line trunk group, that is to say of a second line trunk group - and conversely, in which arrangement their local group processor also takes over all control functions (for the local group processor of the first line trunk group). The local group processors of all first ones of the two line trunk groups in each case associated with one another in pairs are connected via the switching network taking up operation for the impending switching to standby to their corresponding central processor and loaded by the latter with all the required software. In the meantime, the switching operation is continued with the second local group processors in each case until the loading procedures have been concluded and switching to standby takes place from the central switching network and central processor and the temporary switching-over of the subscriber lines and/or junction lines within each of the pairs of line trunk groups is cancelled again.

Title: Low profile composite material bedding foundation system and methods of manufacture.
Inventor: QUINTILE MARK J
IPC: A47C23/00
Filed: 1996-06-06
Abstract: A low profile composite material bedding foundation system and methods of manufacture and assembly uses spring modules made of molded composite materials and supported by inner frame members. The low-profile of the spring modules, and the composite material spring property of return to uncompressed state from total depth deflection without set, greatly decreases the height of the bedding foundation in which the spring modules are attached directly to foundation frame members. The small size and simple geometry of the spring modules is especially suited for flexible arrangement and automated assembly of low-profile foundations.

Title: Fire and explosion suppression
Inventor: GRIGG JULIAN
IPC: A62C2/00
Filed: 2002-03-28
Granted: 2004-11-10
Abstract: A fire or explosion suppression system comprises a source ( 30 ) of a liquid suppressant under pressure, and a source ( 32 ) of an inert gas under pressure. The liquid suppressant is a chemical substance having a low environmental impact, with a short atmospheric lifetime of less than 30 days. The inert gas may be nitrogen, carbon dioxide, argon, neon or helium or mixtures of any two or more of them. The suppressant and the inert gas are fed under pressure to an output unit ( 34 ) comprising a mixing chamber in which the liquid and the gas impinge to produce a mist of the liquid suppressant of very small droplet size which is entrained in the pressurised gas together with vapour from the liquid, the so-entrained mist and vapour and the gas being discharged by a nozzle ( 44 ) into an area to be protected. The mist and vapour are therefore carried by the entraining and transporting high pressure gas into regions of the areas to be protected, enabling a total flooding capability. The inert gas also performs a fire or explosion suppressing capability.

Title: Apparatus for use in processing a substance in a fluidized bed
IPC: C01B3/44
Filed: 1979-11-29
Granted: 1983-07-27
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.
