Title: Electrically controlled fuel injection system
IPC: F02D41/12
Filed: 1975-09-05
Abstract: 1519184 Regulating IC engines NISSAN MOTOR CO Ltd 5 Sept 1975 [5 Sept 1974] 36611/75 Heading F1B [Also in Division G3]  In an electronic fuel-injection system for an I.C. engine, fuel-injection and timing is controlled according to measured values of intake manifold air-flow, throttle position and engine speed as sensed from the engine distributer. The fuelinjection is stopped when the engine speed is greater than a predetermined value and the throttle opening less than a pre-set value, and a device, electrically connected to the system, prevents the ceasing of fuel-injection under certain conditions. As shown, the device comprises at least one of switches 28, 30 operated by an engine gear lever or speedometer respectively, which open when a neutral gear is selected or the engine is underspeed, and thus prevent the ceasing of the fuelinjection. Switches 28, 30 are in series with an electrical switch 16 operated by the engine throttle 18. The provision of switches 28 or 30 is said to eliminate stopping of the engine resulting from a slow control system response e.g. to variations in engine speed.

Abstract: 877,053. Press-button retractive switches; indicators for switches. IGRANIC ELECTRIC CO. Ltd. Nov. 25, 1957 [Feb. 19, 1957], No. 36635/57. Class 38 (5). A pilot light is combined with a change-over switch such that manual pressure on the lens unit 62 operates the switch to energize the lamp for the purpose of testing its condition. In the embodiment shown, a transformer 36 with insulating base 31 is clamped between a switch unit 38 and a member 56 by two screws 48, 49 which enter tapped holes in member 56. The assembly is mounted on a panel 63 by means of a threaded ring 64 which engages an upstanding threaded part of member 56; a cork gasket 65 provides a liquid-tight seal. A lamp holder 51 is fitted on the upper casing of transformer 36. A lens holder 57 is slidable in member 56 against the action of a spring 58 located between a shoulder on holder 57 and an internal flange 56e in member 56. A metal washer 61 is secured to the lower end of holder 57 and acts as a back stop against flange 56e. A synthetic rubber sealing ring 59 is located in a groove in holder 57. Openings near the base of members 56 and 64 allow any liquid that may penetrate the seal to drain away when panel 63 is vertical. A push-rod 39 extends from lens holder 57 through part 31 into the switch unit 38 where it engages one end of a pivoted brass contact bridge 75 which is biased by a spring 74 so as normally to bridge contacts 76 and 77 (see Fig. 9). On depression of the lens holder 57, the rod 39 causes bridge 75 to leave contact 77 and interconnect contacts 76 and 78, putting the primary of transformer 36 directly across the supply and lighting low voltage lamp 52 which is connected to the transformer secondary (Fig. 4, not shown). In an alternative embodiment (Figs. 14 to 22, not shown), a relatively high voltage lamp is used, the transformer 36 being replaced by a dropping resistor, and the lens holder is modified to accommodate the larger lamp, but the same switch unit operated by a push-rod is retained.

Abstract: 363,815. Uniting by fusion. QUASIARC CO., Ltd. and STROHMENGER, A. P., 15, Grosvenor Gardens, London. Dec. 12, 1930, No. 37540. [Class 83 (iv).] An arc welding electrode or welding rod has a metal core surrounded by a flux coating together with one or more carbohydrates such as starch or cellulose and one or more compounds which are normally stable but which evolve oxygen on heating, such as potassium or sodium dichromate, a perchlorate or nitrate. The reaction between the carbohydrate and oxygen producing salt is stated under the high temperature of the arc to produce an atmosphere of hydrogen and carbon dioxide. The use of a dichromate also serves to reduce the arc resistance. A mixed yarn of blue asbestos and cellulosic material may be impregnated with the salt which evolves oxygen either before or after application to the core or the cellulosic material and the salt may be included in a paste placed between the core and a blue asbestos yarn coating. The flux coating may contain 10 per cent of a carbohydrate which has previously been boiled in a 25 per cent solution of potassium dichromate, all but 40 per cent of the liquid removed and the moist material dried at a temperature below 100‹ C. In the final mixture the dichromate amounts to 20 per cent of the carbohydrate. With heavy coatings the carbohydrate amounts to from 10 to 20 per cent of the total flux.

Abstract: 1,201,911. Surface treatment of refractory brick. TETRONICS RESEARCH & DEVELOPMENT CO. Ltd. 7 Aug., 1967 [24 Aug., 1966], No. 37875/66. Heading ClM. [Also in Divisions H3-H5] A refractory non-conducting brick is surfacetreated by directing a plasma jet from a blow torch into a narrow passage defined between the surface of the brick and a separate counter electrode so that the surface of the brick melts and becomes conducting, thus causing the plasma arc current to flow from the torch through the brick surface and to the counter-electrode. The surface layer formed on the brick is stated to penetrate much deeper than layers produced by non-transferred arc plasmas. The brick may be preheated. A firebrick of the following composition: SiO 2 , 52À3%; TiO 2 , 0À5%; Fe 2 O 3 , 3À7%; Al 2 O 3 , 36/39%; CaO, 0À2%; MgO, 1À0%; K 2 O, 0À4%; Na 2 O, 0-2%, was surfacetreated in a transferred arc plasma as described for eight minutes to produce a glassy surface which was 10 mm. thick. The above brick was also treated as described whilst powder was introduced into the plasma. The powder contained 1 part CaO, 2¢ parts Al 2 O 3  and 6 parts of ZrO 2  (by weight). A fireclay sleeve rod was given a similar surface treatment whilst being rotated. One part by weight of CaO, 2 parts of powdered aluminium, and 16 parts of zircon powder (i.e. 65% ZrO 2  and 34% SiO 2  approximately) were added to the plasma. Instead of introducing substances into the plasma, the surfaces to be treated may be painted with the material it is desired to introduce. In one example a mixture containing 1 part CaO, 3 parts MgO and 20 parts of monazite sand (containing approximately 7% thoria) was made into a paste with water and linseed oil. The paste was painted on to the ceramic body, preheated in a muffle furnace, and then treated with plasma. Other additives such as carbon. aluminium nitride, titanium nitride, titanium diboride and forsterites may be employed.

Abstract: Benzyl-o-benzoic acids of the following general constitution:- <PICT:0347171/IV/1> wherein R and R1 both represent hydrogen, or together stand for a dibasic organic acid residue such as the phthaloyl residue, or R represents hydrogen while R1 represents an acidyl residue such as acetyl, benzoyl, toluenesulphonyl; R11 represents hydrogen, methyl, methoxy, ethoxy, halogen, carboxylic or sulphonic acid or other monovalent substituent, and Hal. is a chlorine or bromine atom, are prepared by treating the corresponding body having a free 61-position with chlorinating or brominating agents.  Catalysts may be employed in the halogenation process and it is preferable to start with the 31-acidylamino derivative.  For the preparation of some halogenated acidylamino derivatives, however, it is advantageous to first halogenate, saponify if necessary the halogenacidylamino derivative so obtained, and acylate this as required.  In examples 61-halogen derivatives of the following are obtained : (1) 31-acetylamino-41-methoxybenzyl-o-benzoic acid by bromination in acetic acid and by similar chlorination; the products may be hydrolyzed to the free bases : (2) 31-acetylamino-41-chloro-benzyl-o-benzoic acid by treatment with sulphuryl chloride in acetic acid; the product of bromination of this body is also mentioned, and the free bases obtained by hydrolysis of both derivatives : (3) 31-acetylamino-41-ethoxybenzyl-o-benzoic acid by treatment with sulphuryl chloride in acetic acid; the 61-bromoderivative of this body and of the corresponding 31-amino-41-ethoxy compound is also mentioned : (4) 31-acetylamino-41-methylbenzyl-o-benzoic acid by bromination in acetic acid or by similar chlorination by means of sulphuryl chloride.  Further examples describe the acylation of 31-amino-41-methoxy-61-chlorobenzyl o-benzoic acid with phthalic anhydride, and of 31-amino-41-methyl-61-chlorobenzyl-o-benzoic aci with p-toluene sulphonic acid chloride and benzoyl chloride.  The treatment of a symmetrical urea falling within the terms of the starting materials defined above, with halogenating agents is also mentioned.  The products may be used for the preparation of the corresponding anthrones (see Specification 347,195).  The starting materials for the process are obtained according to the process of the parent Specification.  The Specification as open to inspection under Sect. 91 (3) (a) also includes the whole of the subject-matter comprised by the Specification 347,195, but this subject-matter does not appear in the Specification as accepted.
