Title: Motor vehicle steering wheel assembly with a safety air bag
IPC: B60R21/20
Filed: 1972-02-01
Abstract: 1308889 Inflatable crash bag; steering wheels FORD MOTOR CO Ltd 1 Feb 1972 [27 Feb 1971] 4622/72 Headings B7B B7H and B7J An inflatable crash bag assembly which can be attached to a dished steering wheel spoke includes a gas generator 6, a deformable housing 16 containing the folded air bag 14 and a cover 15. The gas generator 6 is located in a recess in the steering wheel hub 2 and includes charges 10 and detonators 11 which are connected by contacts 12 and leads 13 to a trigger device operated in the event of a collision. When the charges 10 are ignited the resultant hot gas initially flows into lateral chambers (not shown) and then into the central space 5 and out through a diffuser plate 9 into the air bag 14. The lower edge of the air bag 14 and a flange on the housing 16 are fixed to the gas generator housing 6 by a clamping ring 19. The housing 16 is formed of synthetic material and is funnel shaped with a thickened rim 22 at its top edge. The cover 15 is attached to the rim 22 by snap or interlocking fasteners 23 and is provided with weak points which will rupture when the bag is inflated. The assembly is secured to the steering wheel by screws 30 which are threaded into lugs 26 formed on the gas generator housing 6 and into the rim 22 of the housing 16. In minor collisions where the air bag does not inflate the air bag assembly acts as a conventional safety cushion.

Title: Improvements in the manufacture and production of wetting, cleansing, dispersing andlike agents
Filed: 1934-02-14
Abstract: Products stated to have wetting, washing, and dispersing properties are obtained by sulphonating, neutralizing and extracting with an organic solvent mixtures comprising fatty acids and alcohols having a carbonyl value of 10 or below which are derived from nonaromatic hydrocarbons containing more than twelve carbon atoms by the following processes: (a) the hydrocarbons are oxidized in the liquid phase and subsequently hydrogenated until the carbonyl value is reduced to 10 or below or (b) the hydrocarbons are oxidized in the liquid phase in the presence of boric, acetic or benzoic acids or their anhydrides.  The sulphonation is effected under mild conditions whereby the alcohols are converted into esters whereas the fatty acids remain substantially unattached.  The unoxidized hydrocarbons and neutral substances extracted by the organic solvent may be subjected to further treatment.  In examples: (1) a middle oil obtained by the hydrogenation of lignite is oxidized in the presence of manganese stearate and the carboxyl value is reduced to 8 by hydrogenation in the presence of a cobalt catalyst; the product is treated with chlorsulphonic acid in benzine and ether, neutralized with aqueous soda separated, and extracted with benzine; (2) hard paraffin wax is oxidized in the presence of benzoic acid anhydride or boric acid and sulphonated and worked up as in example 1.  For ] the oxidation, naphthene hydrocarbons, hydrogenated brown or mineral coals and paraffin oil may be used.
