A lace pattern comprised of a repetitive pattern of squares circumscribing small six-sided figures and a method for its manufacture on a raschel warp-knitting machine. The lace closely approximates laces made on bobbin-net machines and is dimensionally stable along both of its principal axes.

Berberine and protoberberine analogs thereof are oxidatively dimerized in the presence of a base. Treatment of the dimer with alkanolic anhydrous acid yields the corresponding 8-alkoxyberberine (or protoberberine) phenol betaine which, in turn, may be converted to alpha and beta hydrastine.

A substantially linear polyhydroxy polyether, which (1) is composed substantially of aromatic units and aliphatic units, the proportion of the aromatic units being 50 to 98 mole % based on the total amount of the aromatic units and the aliphatic units, (2) has an intrinsic viscosity, measured at 25.degree. C. in o-chlorophenol, of from 0.3 to 2 dl/g, and (3) has a glass transition, temperature of from 30.degree. to 120.degree. C. Two processes for preparing the polyhydroxy polyether are proposed...

A process for the catalytic hydrogenation of an unsaturated compound using a nickel-silica catalyst. The catalyst comprises aggregates which have an average particle size ranging from 2 to 100 micrometers and said aggregates have outer surface which is at least 60% free of carrier particles.

A hydrogenation catalyst is disclosed, said catalyst consisting essentially of 10-90 parts by weight of nickel and 90-10 parts by weight of silica and having an overall active nickel surface area of 70-200 m.sup.2 /g. A two-step process for preparing the catalyst is also disclosed.

Modified aminoplast resin comprising: (a) 60 to 99.5% by weight of an aminoplast precondensate which has been etherified with a lower alkanol to an extent not exceeding 10% and (b) 0.5 to 40% by weight of a modifying agent which comprises a mixture of (i) a water-soluble polyester prepared from carboxylic acids with at least one carboxyl and dihydric or polyhydric alcohols, and (ii) sufficient free diol or polyol whereby the mixture has a ratio of the sum of free and esterified hydroxyls of 0.8 ...

A softener emulsion for making textiles water-repellent and improving their handle is prepared by melting a mixture of R--NH--CO--NH--CH.sub.2 --(O--CH.sub.2 --CH.sub.2).sub.n --OR.sup.1, R.sup.2 --CO--NH--CH.sub.2 --(O--CH.sub.2 --CH.sub.2).sub.n --OR.sup.1, R--NH--CO--NH--CH.sub.2 OH and R.sup.2 --CO--NH--CH.sub.2 OH together with an anionic emulsifier and emulsifying the melt into an emulsion with water and alkaline earth metal ions.

Insecticide composition comprising (E)-.beta.-farnesene as a contact insecticide against aphids, a process for preparing said composition and the use of the (E)-.beta.-farnesene for controlling aphids.

A demolition agent which acts by means of expansive stress generated upon hydration and which is prepared by calcining limestone at 1300.degree. to 1600.degree. C. to produce a hard-burned quick lime whose crystal sizes are 10 to 100 micron, pulverizing the resulting hard-burned quick lime to 1500 to 5000 cm.sup.2 /g (Blaine), mixing 5 to 70 parts by weight of a hydraulic material to 30 to 95 parts by weight of the hard-burned quick lime and furthermore adding 0.1 to 5 parts by weight of an admi...

Laminated plastic sheets composed of a first layer of a film of an aromatic hermoplastic polycarbonate or polyarylsulfone and a second layer of a film of a thermoplastic copolymer of tetrafluoroethylene and of a completely or partially fluorinated vinyl alkyl ether or vinylalkane and an interlayer of a polyurethane adhesive between the film layers to secure the film layers to one another. Also disclosed are methods for producing the laminated plastic sheet and articles formed therefrom. Such she...
