Title: Device for the continuous seperation of solid/fluid mixtures of all kinds
IPC: B01D33/04
Filed: 1975-08-05
Abstract: 1519634 Moving band press filter HAMAKO HARTMANN MASCHINENBAU KG 5 Aug 1975 [13 Aug 1974] 32641/75 Heading B1D An endless band of filter cloth 10 is folded over to form a tube and passed through a filling and filtering zone and one or more pressing zones (2-4, Fig. 1, not shown) then opened out and cleaned. In the filling and filtering zone a flat nozzle 13 injects liquidsolids mixture under pressure from a pump into the tube which is then carried through a supporting means in a direction between horizontal and vertically downwards. The supporting means in Fig. 3a comprises a pair of stationary channels with filtrate drainage grooves 15. The channels may be relatively adjusted and may converge together. Other cross-sections, including circular (Fig. 3b not shown) are possible. In Fig. 5a the supporting means comprises two endless belts, which may be grooved or mesh-like (Figs. 8a-8d not shown). In Fig. 6 (not shown) the belts are replaced by rows of rollers. In the pressing zone(s) (Figs. 9, 10 not shown) the filter cloth tube and contents pass between further endless belts, converging in the direction of travel and backed by rollers which are urged together by respective pairs of rams (22). Filtrates from the filtering and pressing zones are separately collected. The endless belts could be common to filtering and pressing zones (Fig. 4 not shown). Modular construction however allows any required number of pressing zones to be added to the apparatus. At the cleaning zone (Fig. 12) the cloth band 10 is opened up and solids removed by upper plate 60 with a peripheral rubber or plastics scraper (Fig. 13, not shown), and the cloth is cleaned by water sprays 29 and/or rotary brushes and/or compressed air nozzles. Lower plate 60 collects the wash water. Upper plate 60 is pivoted, adjustable towards the cloth and may be vibrated to assist solids removal.

Title: Improvements in fuel-supply systems provided with filtering apparatus
Inventor: SKELLERN JOHN
IPC: B01D37/04
Filed: 1955-11-15
Abstract: 830,512. Gas turbine plant. NAPIER & SON Ltd., D. Nov. 6, 1956 [Nov. 15, 1955], No. 32671/55. Class 110 (3). [Also in Groups I, XXVIII and XXIX] In a fuel metering system for a gas turbine, unfiltered fuel is drawn through supply line 30a and delivered by a variable delivery pump 30 to filter 31 (see Group I). Dirty fuel from the filter 31 passes through a passage 32, pressurizing valve 33, a main flow control orifice 34 and valve 35, passage 36 of which leads to the engine burners and passage 37 to atmosphere. Filtered fuel from the filter 31 passes to a constant flow metering unit 39 of the type described in Specification 800,511, which meters a constant flow sufficient for the combined needs of the pilot metering unit 40, of the type described in Specification 790,052. The unit 40 meters a predetermined percentage of the engine fuel requirements to any required parameter, e.g. compressor inlet temperature or pressure or pilot's manual control, and passes this flow through a pilot flow orifice 42 to join the remainder of the fuel spilled through the spill valve 43, which then passes through a constant pressure drop valve 44 and is returned to the supply line 30a. A flow proportioning device 45 senses the respective pressure drops across the orifices 34 and 42 and operates to control the operating servo 46 of the pump. A by-pass line 54 containing a non-return valve 55 is provided to allow filtered fuel to pass into the line 32 to the burners on starting.

Title: Improvements in electric line protective systems
IPC: H02H1/00
Filed: 1939-12-22
Abstract: 541,993. Protective cut-out systems. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. Dec. 22, 1939, No. 32800. Convention date, Dec. 31, 1938. [Class 38 (v)] In protective systems employing wattmeter type distance or directional relays on lines connected to the star windings of star-delta transformers, faulty operation due to interphase faults on the delta side is prevented by locking the system when such faults occur, the locking being effected either by definite prevention or by increasing the operating time. The theoretical considerations are fully explained with the aid of mathematics and vector diagrams illustrating the different types of fault to which such a system can be subjected. In the Figures 1, 2, 3, 4 are the phase lines and neutral of a potential transformer star-connected to the line to be protected by means of a distance-relay (not shown), and 5, 7 are minimum-voltage relays, the contacts 8, 10 of which control a locking relay 11 adapted to open a contact 13 which locks the distance-relay. With an inter-phase fault on the delta side the corresponding star-voltage U 1 , Fig. 3, decreases and the current I, in that phase increases; thus one of the contacts 8 .. 10 changes over and energizes relay 11. The setting is such that there is no operation when, due to an interphase fault on the star side, two line-voltages decrease, the maximum value of such decrease being only 50 per cent. of the normal. With a three-phase fault, all relays may release but the connections of contacts 8 .. 10 are such that no operation of 11 takes place. With an earth fault which might produce operation, the circuit of 11 is opened at contact 18 of a residual voltage relay 14. The relays may alternatively be of the minimum impedance type. If relays are used operating on the principle that the normal ratio of star to line-voltage or of current to difference-of-current is upset, two relays will'operate with an interphase fault on the delta side and one with a fault on the star side, there being no operation with a three-phase fault. Thus in Fig. 7, relays 5, 6, 7 having operating coils 8, 10, 12 energized by star-voltages and restraining coils 9, 11, 13 energized by line voltages, control interconnected pairs of contacts for making the circuit of the locking relay 21, provided no earth fault opens contact 24. In Fig. 8 (not shown), each operating coil is energized by the current in one line and the corresponding restraining coil by the difference between the currents in the other two lines.

Drawings to Specification..[Class 35] A multiplex commutator winding, particularly for three-phase machines, has an auxiliary simplex winding of different pitch in the same slots and connected in parallel with it at each pair of commutator segments such that the E.M.F.s induced in the coils connected to the same segments are different by such an amount as to produce a circulating current displaced by 90-180 degrees relative to the working current of the machine. For a motor running below synchronism or a generator running above synchronism, the voltage induced in the main multiplex winding is greater than that induced in the auxiliary winding, whilst for a motor running above and a generator running below synchronism it is less. If the machine may run under a variety of conditions the voltages in the auxiliary and main windings may be nearly equal but with displaced phases. The main winding may be lap wound and the auxiliary winding wave wound or the main winding may be wave and the auxiliary lap.
