Title: Fuel-cell batteries
IPC: H01M8/24
Filed: 1972-09-20
Abstract: 1392217 Fuel cells SIEMENS AG 20 Sept 1972 [20 Sept 1971] 43630/72 Heading H1B In a fuel cell battery wherein electrolyte is supplied to and discharged from the cells by ducts 8, 10 formed by respective aligned apertures in the frames 1 supporting the cell components (Fig. 1), the apertures communicating with the electrolyte chambers by means of bores 9, 11 in the frames, to prevent short-circuit leakage current through the electrolyte, in the operative position of the battery ducts 8, 10 are in the upper region of the frame, and the base 12 of supply duct 8 is at least as high as the point 14 where bore 11 leads into the discharge duct. In operation, electrolyte is only circulated intermittently and when it is not being circulated the supply duct is empty as a result of electrolyte draining back into storage vessel (37) (Fig. 3, not shown). Preferably the point 14 which determines the electroyle level is higher than level 15 so that the electrolyte chambers remain filled. Preferably also, bores 11 lead into duct 10 at above the base of duct 10. Hydrogen and oxygen may be supplied through ducts 3 and 5, and discharged through ducts 4 and 6, associated cross channels communicating with the cells. Bores 7 are provided for bolts for holding the assembly together. Figs. 2a, 2b illustrate a battery comprising cells 23 supported in frames 24 and connected in series by nickel sheets 25 which also provide gas partitions, the assembly being closed by polymethyl methacrylate end plates 21, 22. As shown electrolyte supply duct 28 and discharge duct 29 are both inclined to the axis of the battery to ensure complete discharge of electrolyte. The same effect may be more economically achieved by operating the battery at a small angle to vertical. Preferably the ducts are coated with waterrepellant material e.g. p.t.f.e. or polyethylene to prevent a film of electrolyte remaining. A bypass duct 34, disposed at one end face of the battery, connects the supply and discharge ducts to equalize pressure therein and includes float valve 36 to prevent passage of electrolyte By-pass duct may also communicate with the electrolyte storage vessel by a further duct (39) (Fig. 3, not shown) and a means for removing water of reaction may be provided.

[Also in Divisions H1D and H1X] A field effect image storage converter (see Division H1) comprises a mosaic of photoemitting elements, an insulating layer, a field effect semi-conductor layer and an electroluminescent layer, the latter containing interdigital transparent conducting electrodes whereby the charge pattern acquired by the mosaic on exposure to electromagnetic radiation (e.g. U.V. and light), controls, by its field effect on said semi-conductor layer, the local current flow in the phosphor (from an A.C. or D.C. source) and hence the light output pattern. The mosaic layer may be in contact with the insulating layer (Fig. 2, not shown) or curved and spaced from the remaining screen layers (Fig. 3, not shown) and used in combination with an optical lens. A cylindrical photo-emissive collector electrode may be grounded and illuminated for charge pattern erasure. The device is operable in other than vacuum and if U.V. radiation is employed, photo-emitting materials such as pure metals or magnesium oxide, stated to be unaffected by air, are employed. Examples of phosphor materials are oxides and sulphides of zinc, cadmium and magnesium, zinc sulphide with copper and/or lead, and zinc orthosilicate with manganese; semi-conductors: oxides of lead, cadmium or zinc, cadmium sulphide, antimony trisulphide, germanium and silicon; insulators: silicon monoxide or dioxide, calcium fluoride and aluminium oxide; photo-emitters: antimony-cesium compounds, and mixtures of silver - oxygen - cesium, bismuth - oxygen - silver - cesium.

Abstract: 997,827. Resilient mountings. KINS DEVELOPMENTS Ltd. Jan. 21, 1964 [Nov. 22, 1962], No. 44184/62. Addition to 878,222. Heading F2S. In a method of mounting a bridge structure a bridge beam 11 is supported upon an abutment 12 by first placing a precast concrete beam 14 carrying a superposed bearing 13 of the kind described in the parent Specification within a recess formed, e.g. during casting, in the abutment 12, aligning the precast beam 14, e.g. by wedges and packs, into its correct position, mounting the bridge beam 11 upon the bearing 13, and finally grouting in the beam completely filling the recess in the abutment 12. The bearing 13 may be secured, e.g. by gluing or bonding, or fitted by corresponding projections and recesses, to the beam 14 before the latter is placed in the recess in the abutment 12. A slot 15 in the upper face of the bearing 13 receives a corresponding rib on the underface of the bridge beam 11, alternatively the rib may be formed on the bearing 13 and the corresponding slot in the underface of the bridge beam. In another arrangement a curved bearing 13 is located between correspondingly curved opposed faces of the beams 11, 14. In a modification, Fig. 3, the bearing 13 carries a dowel pin 18 the upper and lower portions of which extend respectively into the beams 11, 14. In a further modification, Fig. 4 (not shown), the dowel pin is attached, e.g. by welding, to the upper bearing-supporting face of a steel girder of T cross-sectional shape which is. accommodated in the recess in the abutment 12. In another arrangement, Fig. 6 (not shown), the bearing 13 has a mild steel bar welded along the central longitudinal axis of the upper face of the T-section girder, the corresponding raised rib-like portion on the central part of the bearing being received in a corresponding groove in the lower surface of the beam 11. Fig. 8 shows a T-section beam levelled by means of blocks 26 and having its web depending into a recess 27 in the abutment 12. The T-section beam may be replaced by one of I-section. In the case of concrete beams, instead of being precast, they may be cast in situ.

Title: Hf choke coil arrangements
IPC: B60S1/02
Filed: 1977-11-09
Abstract: In the case of this antenna system, the resistance wires (12) of a window heating system (11) are used as an antenna. This allows broadcast-radio reception in the long-waveband (150-275 kHz) in addition to the medium-waveband and short-waveband. For this purpose, the RF inductor coil (31), which is connected between the vehicle battery (17) and the resistance wires (12), has a magnetic core which is composed of two different cores (311, 312). The two cores have different losses in the long-waveband, with the aim of better suppressing interference in the long-waveband. One (311) of the magnetic cores is of a type having low losses, while the other core (312) has relatively large losses in the long-waveband. As a result of this construction of the RF inductor coil (31), the losses are at a maximum in the long-waveband, while the induction value does not change. This results from the fact that the characteristic of the frequency/antenna gain has a flat response in the long-waveband when the Q value of the resonant circuit formed from the antenna capacitance and the induction of the RF induction coil is reduced. <IMAGE>
