Filed: 1954-12-13
Abstract: 792,661. Gas turbine plant. BENDIX AVIATION CORPORATION. Dec. 13, 1954 [Jan. 8, 1954], No. 36045/54. Class 110 (3). [Also in Groups XXXV and XL (c)] Fuel injection mechanism for a gas turbine engine control system (see Group XXXV) comprises a main fuel metering valve 50 actuated by a motor-generator 49 in response to temperature and speed signals from the electronic circuits of the control system, to which is returned a signal from a feed-back potentiometer 51, driven by motor-generator 49, representing the valve setting. The fuel is pumped through an inlet 590 to a chamber 592, and thence to the outlet 616 via main valve 50, check valve 606, cut-off valve 610 and a pressurizing valve 614; valve 610 being operated through the linkage 622 by the throttle. A diaphragm 596, operating a by-pass valve 594, maintains the required pressure differential across the valve 50, since it is subjected to the fluid pressures in chambers 592, 598, the latter having communication with a chamber 608 on the downstream side of valve 50 through the conduits 630, 632. The valves 634, 640, operated by a bellows 636 in response to changes iu the compressor inlet pressure, allow a minimum flow through conduits 630, 632, 638 to by-pass main valve 50. An annular indentation 642 in valve 610 allows a by-pass flow if the latter is in the full cut-off position to prevent excess pressures in the apparatus; any such pressure in chamber 598 causes diaphragm 596 to move to the left, thereby opening by-pass valve 594 to return fuel to the pump.

Title: The manufacture of new vat dyestuffs containing nitrogen
IPC: C09B3/78
Filed: 1932-12-29
Abstract: Nitrogenous vat dyes are derived by reacting with such nitrogenous compounds as contain in the molecule one or more replaceable hydrogen atoms attached to nitrogen, on condensation products obtainable according to Specification 369,765 by treating glyoxaldianthraquinone compounds with an acid condensing agent with or without previously converting them into alkali-condensed products, the said condensation products probably having the general formula <FORM:0410552/IV/1> wherein one or more of the radicles X stand for halogen, the rest being hydrogen.  These halogen derivatives are derived either by starting from a halogenated anthrone or from the halogenated glyoxal-dianthraquinone compounds and carrying out the process of Specification 369,765, or by working under such conditions as to introduce halogen atoms into the molecule during formation of the products, or by subsequent introduction of halogen into the molecule. The nitrogenous products dye in brown shades and can be further converted into other products by treatment with acid or alkaline condensing agents.  In examples (1) the condensation product derived by alkali fusion, then aluminium chloride fusion of 2-chloranthrone condensed with glyoxalsulphate is condensed with a -aminoanthraquinone (reddish-brown), 1-amino-4- or 5-benzoylaminoanthraquinone (black-brown); condensing the latter with the corresponding halogen derivative obtained by using 3-chloranthrone yields a similar dye; the foregoing dye derived by using 1 - amino - 4 - benzoylaminoanthraquinone may be subjected to aluminium chloride fusion (dyes currant); (2) the condensation product similarly derived to (1) above from 1-chloranthrone is condensed with a -aminoanthraquinone (dark brown) followed by alkali fusion (yellow-brown), 1-amino-4- or 5-benzoylaminoanthraquinone (brown) followed by treatment in chlorsulphonic acid (brown), 1 - amino-4-methoxyanthraquinone (brown), 1 - amino-4-chloro- or -6-chloroanthraquinones, 2-aminoanthraquinone, p-toluenesulphonamide (the latter product losing the sulphonic acid radicle on gently warning in concentrated sulphuric acid); (3) the glyoxal-dianthraquinone compound derived from 2 - chloranthrone is brominated in sulphuric acid monohydrate to give a dibromo derivative which is condensed with 1-aminoanthraquinone (violet-brown); (4) the condensation product from 4-chloranthrone and glyoxalsulphate is oxidized in monohydrate with potassium persulphate and the product condensed with 1-aminoanthraquinone (reddish-brown); on after-treatment with chlorsulphonic acid a yellow-brown dye is obtained.

Filed: 1968-08-05
Abstract: 1,210,306. Valves. LUCIFER S.A. 5 Aug., 1968 [14 Aug., 1967], No. 37241/68. Heading F2V. Flow between an inlet 2, outlet 3 and an exhaust 34, is controlled by a part electrically and part manually operable valve having two closure members 10 and 13 which are contained within a ferromagnetic core 7. In the state of the valve shown, flow takes place solely between the inlet 2 and outlet 3 with the electromagnetic coil 19, regardless of its state, having no effect upon the core 7 as the latter is rendered immovable by a rod 21 and a spring 24 acting thereon. Upon depressing and then rotating a push-button 22, a protruding flange 29, formed integrally with a fixed ferromagnetic member 18, firstly moves along a longitudinal groove 28 and then enters an arcuate groove 30, both formed in the button, so locking the button in its depressed state. Such action nullifies the effect of spring 24 and so allows a spring 8 to move the core 7 downwardly and hence member 10 to be seated. Subsequent unseating of the valve member 10 can be achieved by energizing the coil 19, with the rod 21 acting as a visual indicator of any movement imported to the core 7. With the core 7 in its lowered position flow from the outlet 3 can take place to exhaust 34 via two longitudinal grooves 12 formed in the core, an axial passage in the push button and an annular collecting chamber 33. In an alternative embodiment (Fig. 2, not shown), visual indication of the position of the core 7 is afforded by an external ferromagnetic ring (39) which moves in response to movement of the rod 21, the uppermost end of which carries a permanent magnet (38).

Abstract: 1494310 Vacuum cleaner dust container assembly ELECTROLUX Ltd 13 Sept 1976 [16 Sept 1975] 37775/76 Heading A4F [Also in Division B I ] A vacuum cleaner dust container assembly of the type comprising an air-permeable bag 11 and an end plate 12 having an opening 13 through which dust enters the bag is characterized by the provision of a flow-path for air in the end plate which extends at least partly in the plane of the end-plate. The end-plate may comprise layers 12a, 12b, the latter layer being provided with holes 14, 15 inter-connected by a groove 16, the arrangement being such that when the layers are glued together, a flow-path for air is formed between the two layers. In a modification, Fig.3 (not shown), the top layer of the end-plate may be provided with a groove, through holes being provided in the bottom layer. Alternatively, a grooved plate may be suitably disposed between the two layers, or a groove may be formed by a recess in both layers, or a through groove may be formed in the bottom layer. The dust container is designed to form part of a system which ensures that the cleaner will only operate continuously if the dust container is present in its working position, as illustrated in Fig.2. In this case, when the cleaner is switched on, negative pressure is applied via hole 30, bellows 29, hole 14, groove 16, hole 15 and channel 24 to space 23 so as to move diaphragm 18 up against the action of spring 19. This causes rod 27 to move up and hold push button depressed, thereby keeping the motor/fan unit running. In the event where no dust container is present, the bellows 29 will expand to contact the end-plate 28 thereby blocking the negative pressure path, and space 23 will be subject to atmospheric pressure. In this case, when the push button is operated to start the motor/fan unit, lack of negative pressure in space 23 causes rod 27 to be held down by spring 19. This means that the push button cannot be held in the depressed ON position, so that when the push button is released, it returns to the OFF position.
