For the purpose of improving the quality and especially the mechanical properties of single- or multi-ply sheets with at least one ply, consisting at least in part of thermoplastically processable starch, the sheets are stretched monoaxially or biaxially after they have been produced.

Polymers with a high glass transition temperature are used in cement additives to produce a portland cement mortar or concrete that does not have the initial stickiness typical of prior art polymer-modified portland cement compositions and does not form a crust on the surface when exposed to air drying, thus improving the working time of the mix. This simplifies equipment cleaning and permits the ...

The semiconductor array has a three-pole array integrated in the semiconductor element and functioning a...

Structural aggregate pigment products with intrinsically built-in functional properties comprising particulate matter treated with complex functional microgels.

There is disclosed a torque transmitting or coupling arrangement for a fastener drive system or the like, wherein the respective externally configured and internally configured components are provided with a series of mating, elliptically curved flutes and lobes. In both the externally and internally configured components, the flutes and lobes are defined by a first series of elliptically curved s...

It is highly desirable for tire treads to exhibit good traction characteristics such as good wet skid resistance. However, it has traditionally been very difficult to improve the traction characteristics of a tire without sacrificing rolling resistance and tread wear. The high performance segmented elastomers of this invention offer a unique combination of desirable characteristics for utilization...

A clothes washing machine for washing clothes in boiling water comprises a tub enclosing a wash tank. The tub has an upstanding wall with a rim. A cover for the tub includes inner and outer downwardly projecting flanges forming a groove extending continuously around the periphery of the cover to prevent the escape of steam. The rim of the tub is tightly received in the groove. A water infeed line ...

In mfg. a necktie, the interlining is cut to the same shape and size as the tie fabric, at right angles to the lie of the yarns, and then applied to the reverse side of the tie fabric with heat. The seam is opened by ironing as soon as the insert is stitched into the points or ends of the tie. The longitudinal seam is stitched as the join between the points and the reverse side. A stiffener is ins...

A circuit for generating internal power supply voltage for a semiconductor memory device includes two separate internal power supply circuits, one for a peripheral reference voltage and the other for an array reference voltage, each operating independently of each other. The internal power supply voltage generator includes: a reference voltage generator 21 for converting an external power supply v...

In a ring-spinning or -twisting machine a longitudinal row of upright and normally rotating spindles mounted on a common support beam each have a lower reserve surface below a sleeve normally carried on the spindle. An apparatus for clearing roving wound on the surface has a guide rail extending longitudinally along a back side of the beam adjacent the spindles, a carriage displaceable along the r...
