IPC: F02M7/24
Filed: 1976-03-30
Abstract: 1531552 Fuel/air mixture control NISSAN MOTOR CO Ltd 30 March 1976 [1 April 1975] 12695/76 Headings F1B and F1H In a spark ignition engine 10 having at least two spark-plugs per cylinder and having exhaust gas recirculation means 44, 48, the air/fuel ratio of the mixture supplied by carburetter 32 is controlled in response to an exhaust gas composition sensor 86 so as to be maintained at stoichiometric. Solenoids 78, 80 are operable to reduce or increase the air-flow through auxiliary air bleeds 66, 76 to the main fuel well 58 and the idle fuel passage 62 in response to control signals from unit 84. The sensor 86 may be responsive to oxygen, nitrogen oxides, carbon monoxide, carbon dioxide or to hydrocarbons. The sparking plugs 22 are located diametrically opposite with respect to the combustion chamber and the exhaust valve ports of each cylinder pair lead to a siamesed exhaust passage 36. A catalytic converter, or afterburner may follow the exhaust sensor to treat the exhaust gases.

Abstract: 465,431. Road - traffic signals on vehicles. CAMPBELL, A., GOLDSMITH, A., and WHITE, F. K. May 6, 1936, No. 12812. [Class 118 (ii)] A direction-indicator in the form of an arrow is of triangular cross-section with one angle downwards so that an arrow is shown when the indicator is turned to left or right or is swung vertically to indicate stop. The indicator normally points in the direction of movement of the vehicle and a " go " indication, such as a green light, is visible to following vehicles. As shown, the indicator is mounted on the roof of a vehicle and the lamp 15 shows a green light through the end of the indicator. Each of the three sides 5 of the indicator is in the form of an arrow having head, shaft and tail and the mounting enables the indicator to be swung to left or right, so that a direction indicator of arrow form is visible to following vehicles, and also to be swung vertically upwards, as indicated in Fig. 3, so that the top arrow is visible and gives a " stop " indication. The indicator comprises a framework 3 of V-shaped metal bars 4 and translucent panels 5, illuminable by lamp 6, the panels having wedge-shaped opaque portions 7 at the ends to give the conventional tail form to the arrows.

The anode wires 60 are located in the "horizontal" slots 30 and may be secured by cement. The cathode strips 70 are located above the "vertical" slots 34 with apertures 74 in register with the slots 30. An auxiliary anode wire 60A<SP>1</SP> is located in an auxiliary slot 30A<SP>1</SP> extending into a portion 34A<SP>1</SP> of the first vertical slot 34A. The first cathode strip 70 is divided into a short portion 70A<SP>1</SP>, overlying the slot portion 30A<SP>1</SP>, and a longer portion 70A. Portion 70A<SP>1</SP> serves to couple auxiliary cell 80A<SP>1</SP>A<SP>1</SP>, formed at the crossing with auxiliary anode 60A<SP>1</SP>, to the first scanning cell 80AA. The last cathode strip 70 is similarly divided into a short portion 70D<SP>1</SP> and a longer portion 70D. The panel 10 is completed by a glass viewing plate 90, the assembly being sealed together by a seal 100, e.g. of glass frit, and provided with a filling tubulation 103. The gas filling may be Ne, A, Xe singly or in combination, and a metal vapour, e.g. Hg, is usually added to minimize cathode sputtering. The gas is preferably a Penning mixture, e.g. Ne + Xe at a pressure of 100-250 torr. and preferably about 175 torr. In a modified panel (Figs. 3 and 4, not shown) the anode wires are located on the top surface and the cathode strips on the bottom surface of an insulating plate provided with a plurality of holes forming the scanning cells. The first hole is enlarged to co-operate with an auxiliary anode and cathode. All the cells in each row are coupled by a horizontal slot provided in the plate, but only a few short vertical slots are provided to couple selected cells at the ends of the rows to complete the scanning raster. In a further modification (Fig. 5, not shown) the arrangement shown in Fig. 1 is provided with a further layer of display cells and associated display anodes. A driving circuit for the panel is described (Fig. 6, not shown).

Filed: 1930-04-28
Abstract: 348,353. Phantom systems. MARINO, A., 6, Viale Mazzini, Rome. April 28, 1930, No. 13024. Convention date, April 27, 1929. Addition to 283,217, [Class 40 (iv), Telephones &c.]. [Class 40 (iv).] Comprises a number of modifications of the system of the parent Specification in which each channel employs all the line conductors. In the system shown in Fig. 3, each telephone set is arranged in series with a number of transformers, one for each line, and the lines are connected to a common point O. In another arrangement, Fig. 4 (not shown), the 8 lines are divided into the 28 possible pairs, 4 pairs being given to each of 7 stations. Each pair is bridged by a transformer winding, the primaries of the 4 of these transformers corresponding to a station being connected in series with the telephone set. Modifications of this system are shown in Figs. 5, 6, 7 in which the primaries are connected in various ways so that the telephone is bridged across two mid-points of the primary circuit instead of being in series with it. In each case use is made of centre-tapped chokes which offer high inductance to circulating currents, but none to the useful currents. Induction preventing. Fig. 8 shows the preferred arrangement of the conductors in the cable, each conductor crossing the other 3 in turn.
