Title: Improvements in spark plugs
IPC: H01T13/06
Filed: 1953-04-15
Abstract: 725,365. Sparking plugs. GENERAL MOTORS CORPORATION. April 15, 1953 [May 2, 1952], No. 10267/53. Class 7 (4). In a sparking plug of which the insulator 6 is enclosed and protected against damage by a shield 14 formed by two separate cylindrical sleeves 64, 68, the latter are jointed together, end-to-end, during assembly in order to accommodate any warping of the insulator 6 by setting themselves at a slight angle to one another. Within the stepped insulator bore is a centre-electrode assembly comprising a firing tip, having a soft-metal core 31 and a heat-resistant sheath 33, a conducting seal 32, a screw member 34, a resistance 36, a spring 38 and a contact cap 40 retained in a groove in the insulator by a shoulder 42. The insulator 7 has shoulders 20, 22 which co-operate, respectively, with a ledge 44 in the shell, and the lower edge 50 of the shield 14 by means of which the insulator is retained in the shell 10. The upper shield-sleeve 68 embodies an upper inturned flange 70 which is of the same diameter as the interior of the upper end 24 of the insulators, a metal gasket 76 filling the space between the top of the insulator and the flange. The lower shield-sleeve 64 is welded or brazed to the shell, the two shield sleeves being similarly secured together after a gauge has been positioned in the top of the plug to ensure that the insulator is concentric with the shield ; this may result in the sleeves 64, 68 being out of alignment with each other. The earth electrode 12 comprises a number of inwardly extending arms which are welded to the shell after a tubular gauge has been inserted in the spark gap ; this provides a spark gap of uniform length and may necessitate the electrode 12 being set at a slight angle within the shell recess 56.

Abstract: 214,823. Helfenstein, A. April 16, 1923. Furnace details.-Continuous furnace electrodes b are formed in place by maintaining a working electrode, of such length that a substantial portion thereof extends outwardly from the part a to which the current is supplied, moulding and baking the raw material m by an externally heated mould e, and finally allowing the baked portion to cool, the moulding, baking, and cooling operations being carried out during the normal feeding operation of the electrode. In the case of large electrodes an inner mould is also used and may be electrically heated if desired. The mould m is surrounded by a heat insulating body f forming a combustion. chamber f<2> having gas connections i and inlets for air to ensure combustion. The mould and combustion chamber are supported by an electrode clamp e engaging the feeding screws d. After a new section has been formed on the electrode the set screws p are operated to grip the electrode, the clamp c is loosened and the mould and combustion chamber are then raised to the necessary position for forming another section. Anchor pieces l are baked into the top portions of the sections to secure good connections one with another. Fig. 4 shows the method adopted when hollow electrodes are to be formed. A series of inner and outer moulds e, e<2> made in segments are employed, and the furnace gases pass through an internal pipe u to the combustion chamber f<2>, the latter being provided with air inlets y and connections to an exhaust main z. A graphite filling t is arranged between the heating devices and the moulds to ensure easy motion during the feeding of the electrode. The moulds e may be fed into the furnace with the electrode, or mav be removed after passing out of the combustion chamber.

Filed: 1956-04-06
Abstract: The invention comprises compounds of the formula: <FORM:0788140/IV (b)/1> and acid addition salts thereof, where R is a lower alkyl or alkenyl group of up to six carbon atoms or a cycloalkyl, cycloalkenyl or aryl group, for example a methyl, ethyl, propyl, isopropyl, butyl, isobutyl, allyl, crotyl, methylallyl, cyclopropyl, cyclohexyl, cyclohexenyl, phenyl or substituted phenyl group, and the preparation of these compounds by reacting hydrazine with an acetonitrile which is substituted in the alpha position by a radical R and treating the product with acid or alkali if desired to convert the product into a salt or the free base.  The reaction is suitably carried out in alcoholic solution in the presence of an acid such as acetic acid. The invention also comprises treating the resulting 4-substituted-3-amino - 5 - methyl - pyrazole or a salt thereof with a benzene sulphonyl halide substituted in the para position by an amino group or an acylamino or nitro group and, when the para substituent is an acylamino or nitro group, converting this to an amino group by hydrolysis or reduction to give the corresponding 3-sulphanilamide pyrazole.  Examples describe the reaction of the appropriately substituted acetoacetonitrile with hydrazine to give (1) 3-amino-4 : 5 - dimethylpyrazole; (2) 3 - amino - 4- 5 - methylpyrazole; (3) 3 - amino-4 - phenyl - 5 - methylpyrazole; (4) 3 - amino-4 - allyl - 5 - methylpyrazole; and (5) 3-amino - 4 - [cyclohexen - (21) - yl] - 5 - methyl pyrazole; the products are treated with N-acetyl-sulphanilyl chloride in pyridine to give the corresponding 3-(N-acetylsulphanilamido)-pyrazoles, which are hydrolysed to give the corresponding 3-sulphanilamido compounds. Starting materials.  The a -substituted acetoacetonitriles used as starting materials may be prepared either by Claisen condensation of the appropriate ester and nitrile, or by splitting off water from the corresponding aceto-acetamide.  For example, a -[cyclohexen-(2)-yl] aceto-acetonitrile is made by reacting 1-bromo-cyclohexene-(2) with acetoacetamide in the presence of sodium ethoxide and splitting off water from the resulting a -[cyclohexen-(2)-yl]-acetoacetamide by treatment with phosphorus oxychloride.
