Title: Wear-resistant composite roll having steel core - has iron alloy concast cover with min. non-grain graphite and high granular graphite at surface to improve resistance to surface roughening
Inventor: HATTORI TOSHIYUKI
IPC: B21B27/00
Filed: 1991-02-28
Abstract: Wear-resistant composite roll is made of a steel core (5) and a cover (8) of composition by wt.% 1.0-3.5C, up to 3.0 Si, up to 0.06 S; up to 300 ppm B; balance Fe plus unavoidable uinpurities; The cover has a solidified structure which has a surface grain carbide of 5-70 % and 5% or less of non-grain carbide. The alloy matrix of the cover has a hardness of min 550 Hv. ADVANTAGE- Surface has good wear-resistance and excellent resistance to surface roughening which leads to longer working life for the roller. This is achieved by reducing the surface content of the non-grain carbide and increasing that of granular carbide and lowering the B content.
Patent DE-4112093-A1 (DE)
Inventor: BRUNKE ERNST-JOACHIM DR
IPC: C07C47/347
Filed: 1991-04-12
Abstract: It was found that 8-exo-formyl-2,6-exo-tricyclo[5.2.1.0<2,6>]decane having the constitution and stereochemistry of formula (I) possesses particularly useful olfactory properties which are clearly superior to those of the 8-endo-epimer and which already have an effect if compound (I) is enriched with mixtures of 8-exo- and 8-endo-epimers. Compound (I) can therefore be advantageously used, in pure or enriched form, as a scent or as a component of perfume compositions. To prepare an enriched epimer mixture, a mixture obtained in a known manner (US patent specification 3 270 061) and having an exo/endo ratio of 1.45:1 is brought into equilibrium by base catalysis, preferably by the action of alkali hydroxides in alcoholic solution, to give an exo/endo ratio of 5.25:1. Alternatively, the enriched epimer mixture can be prepared starting from 8-formyl-2,6-exo-tricyclo[5.2.1.0<2,6>]decene-3(4), catalytically hydrogenated for example with palladium coal and then optionally brought into equilibrium. Or 2,6-exo-tricyclo[5.2.1.0<2,6>]decene-8 can be hydroformylated and also optionally brought into equilibrium. The pure compound (I) is prepared by reducing preferably a mixture of 8-exo- and 8-endo-epimers obtained in the manner known per se to a mixture of the corresponding alcohols, from  which the 8-exo-configured methylol is isolated by chromatography or distillation and oxidized to obtain the aldehyde (compound I) again.

Title: Electrical coupling for vehicle steering column - is formed from number of contacts disposed around vehicle steering column and interconnected by electrical cable
Inventor: DREISSIG HARALD
IPC: B60R16/027
Filed: 1991-06-15
Abstract: The unit comprises a number of metallic contact elements (4) interconnected in series by insulated electrical cable (5) enclosed within a plastic cover (14), the former being disposed around a central point corresponding to the axis of the steering column so that they are able to maintain contact with a contact ring mounted on the steering wheel.
