Title: Load-control and power-distributing system
Inventor: WILDI THEODORE
IPC: H02J3/14
Filed: 1969-02-27
Abstract: 1,233,111. Control systems for a plurality of load devices. GEN-TEC Inc. 27 Feb., 1969 [2 Aug., 1968], No. 10562/69. Heading H2H. A system for supplying a plurality of loads having differing priorities for connection to a source of electricity comprises switching means for connecting the loads to, or disconnecting the loads from, the source according to the priorities thereof in such a manner as to prevent the source becoming overloaded but also to ensure the optimum usage of the supply. In a supply system for a multifloor building having heating devices for each floor together with water heating facilities and snow melting devices, the heating on the ground floor of the building has the maximum priority whilst the heating of the remaining floors has the next priority, each floor having equal priority. The floor heating devices are given priority over the water heating facilities whereas the snow melting devices are given the least priority. The means for connecting the loads to the sources comprise apparatus controlled by the main power source and operate to connect the loads to the source and to disconnect them from the source so as to maintain a given load on the supply. The loads having equal priorities are sequentially connected and disconnected by means of a cycling apparatus having a plurality of inputs and of outputs, means being provided to connect any input terminal to each of the output terminals in turn. Thus each of the equal priority loads are connected to the source for a predetermined interval of time in sequence. When the floor heating loads are further controlled by thermostats and the cycling apparatus reaches a position where the thermostat is operative to prevent the connection of the respective load, the load control apparatus becomes effective to switch in the next load. Should the cycling apparatus then energize a load in the next step of its sequence such that the source becomes overloaded the load control apparatus operates to disconnect the load having the least priority. The cycling apparatus comprises a stepping relay, such as a telephone type relay, controlled by a circuit arrangement including a unijunction transistor gating a thyristor in the relay coil circuit. Should the cycling relay reach the end of its action an inhibiting relay is provided to terminate the cycling action.

Abstract: 1,233,539. Plate assembly for cleaning gases. D. A. METCALFE. 18 June, 1968 [21 June, 1967], No. 28545/67. Heading BIT. Liquid droplets are removed from a gas by passing it in the direction 16 between an assembly of parallel, zig-zag baffles 10 having flange extensions 17 to form traps 18; the spacing between adjacent baffles being such that the gases cannot follow a rectilinear path, but that a straight line can extend through the upstream-downstream direction of any passageway without intercepting the zig-zag portions of the baffles. As described, air containing vegetable oils from a kitchen enters the open end of the baffle assembly and oils collecting in traps 18 trickle downwards into a sump. The assembly may be held in a frame (20) by catches (24) so as to be removable for cleaning, Fig. 3 (not shown). Figs. 6 and 7 (not shown) illustrate an arrangement of two such assemblies in V-configuration within a cooker canopy (28).

Abstract: 1,264,356. Distillation apparatus for reconcentrating glycol and other liquid desiccants. MALONEY-CRAWFORD TANK CORP. 27 Oct., 1969 [27 Feb., 1969], No. 52508/69. Heading BIB. Glycol (or other liquid desiccant) which has been used to dehydrate natural gas in tower 50 is reconcentrated by boiling off a large proportion of the absorbed water therefrom in stripping column 68 and reboiler 70, withdrawing a stream of partially-concentrated glycol from the reboiler through constant-level float-trap 78, passing the withdrawn stream through conduit 80 in heat-exchange with the liquid in the reboiler, and then passing the partially-concentrated glycol into insulated chamber 82, which is maintained under vacuum by a jet pump, wherein the glycol flows down over packing 84 so that flash vaporization of the residual water takes place. Concentrated glycol leaves chamber 82 through conduit 86 and flows through accumulator 64 in heat-exchange with aqueous glycol flowing via coil 95 from tower 50 to column 68. The jet pump connected to the top of chamber 82 is operated by some of the dry gas discharged from tower 50. The vapours and air aspirated from the top of chamber 82 through conduit 92 flow to a natural draft condenser; and the condensate is drawn into the jet pump. The effluent from the jet pump is introduced through conduit 94 into reboiler 70. The reboiler is heated by a tube 72 which contains a gas-burner. In a modified apparatus (Fig. 3, not shown), the flash chamber is evacuated by a diffusion pump and a jet pump connected in series. The jet pump is operated by aqueous glycol under pressure. The diffusion pump is operated by heat from the reboiler.

Abstract: 1305459 Combustion apparatus ISHIGAKI KIKO CO Ltd 23 Feb 1970 8473/70 Heading F4B Combustion apparatus for burning wet particulate material, shown in a developed view, comprises serially arranged drying, heating and burning chambers 6, 7 and 8 through which is circulated a fluidized bed A of incombustible sand or iron particles. Slurry cakes from a filter (not shown) are fed from inlet 38 on to crusher 39 to be dispersed over the fluidized bed A and carried therewith through the chambers 6, 7 and 8. A regulatable hot air supply from lower chambers 15, 20 and 25 both fluidizes the bed and provides drying, heating and combustion air. Exhaust gases are regulatably withdrawn from the chambers through damper controlled outlet ducts 30, 33 and 35 and used to preheat the incoming fluidizing air. The ashes from chamber 8, which contains a burner 43, are separated in a cyclone (not shown) connected to duct 35. The gas pressure in the chambers successively decreases from chamber 6 to chamber 8 to cause the bed to flow through the apertures 13a, 13b interconnecting the chambers. The outlet 14a from chamber 8 is at a higher level than the inlet 14b to chamber 6 so that a sand trap B is formed as the bed flows from chamber 8 to chamber 6 to prevent gas flow in the reverse direction. Alternatively (Fig. 5, not shown), a power-driven rotary seal valve may be provided in the passage interconnecting these chambers. In modifications, the heating chamber may be dispensed with, or they may be more than one such series of chambers in the path around which the fluidized bed circulates.
