A silicone-alkylene oxide copolymer useful in the inhibition of foam formation in media processed by ultrafiltration processes. The copolymers consist of a polysiloxane in which well defined organic pendent groups have been hydrosilylated to the polysiloxane backbone. These copolymers display reversible aqueous solubility which is temperature dependent. They are unique in that they inhibit foam fo...

The disposable nappy has an upper layer (1), which is permeable to liquids, a rear layer (2), which is impermeable to liquids, a liquid-absorbing core (3) which is placed in the manner of a sandwich between the two layers mentioned, and side flaps (4) which extend from opposite side edges of the core towards the outside and are fitted in each case with elastic parts (5). Each of the side flaps (4)...

Drop head for ceiling formwork system comprising a rectangular support plate (14) provided with lateral stops for supporting the formwork supports, two yoke plates (18) projecting downwardly from opposite sides of the support plate (14) and having a centre guide slot (24) closed by a connecting web (28), a connecting member (34, 36, 38, 44 ; 48, 50) with which the drop head may be fixed on the ...

A packaged semiconductor chip which effectively dissipates heat and has improved performance. The packaged chip has a plurality of lead frame conductors (38) extending through the encapsulating material (46) which are adhesively joined to the semiconductor chip (34), preferably by means of an alpha barrier (32). The conductors (38) cover a substantial portion of the surface of the chip (34) and th...

A lens (9) for an optical recording/reproducing apparatus has a graded refractive index n (r) at a position a distance r from its optical axis along a radial direction which is given by: n<2>(r)=n0<2>1-(g.r)<2>+h4(g.r)<4>+h6(g.r)<6>+h8(g.r)<8>+... and the following conditions are satisfied: R2= chi 3.0>/=R1/(1 +0.75S)>/=0.8 1.40/=g.f>/=0.45 where n0: refractive inde...

The patent specification "Mark carrier for adjusters for correcting eye movements" describes a carrier which can be placed on the cornea of the human eye where it retains its position relative to the eye even during movements of the latter. The carrier is intended to receive any optically relevant components as are required, in particular, for trackers for correcting eye movements, especially in (...

Method of identifying workpieces of glass, ceramic or porcelain which are in a hot state. According to the new method, workpieces which are still in a very hot state can be reliably identified without a thermal or mechanical stress being applied to part of the workpiece. A thin carrier layer about 50 to 1000 nanometers thick, serving as an identification field and consisting of a material which co...

In a process for verifying the capacitance of a capacitor (C40), the latter is discharged from a first potential (US1) to a predetermined second potential with a constant discharging current (IK). The discharging time (TE) is measured. The existing capacitance of the capacitor (C40) at a known charging resistance can be calculated from the measured values.
