Title: Decorative braiding prodn. by forming pattern on base weave - and chemically removing base weave to leave patterned braiding
Inventor: DEPRAETER THEO
IPC: D03D15/68
Filed: 1975-01-09
Abstract: A decorative braiding for e.g. edging fabrics etc is formed by producing a base weave in which a decorative pattern is formed from chemically inert yarns, some of the warp yarns of the weave which extend through the pattern also being of chemically inert yarns. The material is then subjected to a chemical process which disintegrates the yarns of the base weave, and which does not attack the chemically inert yarns of the pattern, and of the warp thus to leaving the pattern intact to form a decorative braiding. The method is simpler than forming a decorative pattern on a base weave and then cutting away the base weave.

Title: Helical rib patterns for engaging stacked polypropylene tubs - permitting smooth disengagement by rotation
IPC: B65D21/04
Filed: 1976-07-30
Abstract: Plastic tubs with a base and walls which diverge to allow open topped tubs to be stacked, where each tub features moulded helical ribs on internal and external wall faces.

Title: Semiconductor heterostructures - contg. a transition layer with two-way compsn. gradient
Inventor: MASLOV VADIM NIKOLAEVICH
IPC: H01L29/221
Filed: 1976-08-12
Abstract: Heterogeneous semiconductor structures comprise a substrate and a semiconducting main layer separated by a semiconducting transition layer. The main layer comprises a doped solid soln. ABxC1-X of semiconductor components AB and AC (0= x =1) with a compsn. gradient along its major axis. The substrate comprises a material with crystallographic properties close to those of AB. The transition layer comprises a doped solid soln. ABxC1-x with a compsn. gradient along its major axis and also a compsn. gradient perpendicular to its interface with the substrate. The latter gradient is such that the compsn. varies from that of the main layer (at the interface with the main layer) to that with the max. AB content (at the interface with the substrate). The structures can form the basis of tunable lasers, high-resolution semiconductor spectrometers, and various types of sensors (e.g. for hydrostatic manometers). Unlike heterostructures without the transition layer, the main layer and the substrate can have quite different crystallographic properties. This makes it possible to produce lasers with different and/or wider spectral ranges.
