Abstract: The invention relates to a device structure and crystal growth process for making the same, whereby single-crystal semiconductor layers are formed over metal or composite layers. The metal layers function as buried reflectors to enhance the performance of LEDs, solar cells, and photodiodes. The structure may also have application to laser diodes. The structures are made by a modification of a well-established metallic solution growth process. The lateral overgrowth process can be enhanced by imposing an electric current at the growth interface (termed liquid-phase electro-epitaxy). However, the use of an electric current is not crucial. The epitaxial lateral overgrowth technique was also applied to silicon growth on metal-masked silicon substrates.

Abstract: A bra sport top provides enhanced posture and increased breast support for women engaging in athletic activities. Over-shoulder harnesses encircle each shoulder and serve to urge them back. Cross braces interconnect the two over-shoulder harnesses in a crosswise manner between the shoulder blades. A support belt traveling through a slip sleeve encircles the wearer's torso below the breast and shoulder blades. Interconnecting the over-shoulder harnesses and the slip sleeve are breast-tensioning panels that compress and restrain the breasts so as to prevent any damage to the breast tissue. The left and right breast-tensioning panels may be interconnected by a detachable coupling means or may be connected by elastic bands or the like. Alternative embodiments allow for different directional support of the underlying breast tissue by the breast-tensioning panels.

Abstract: The prior art discloses machines which, for cooling the surface to be machined, have a gas supply line which opens into a gas outlet which is in the direct vicinity of the polishing disk. When CO.sub.2 is used as cooling gas, stoppages, which can be traced back to snow formation of the CO.sub.2, may occur in the line and in the gas outlet. In order to avoid blockages, the machine is assigned means for the supply of the liquid or supercritical CO.sub.2 which comprise a valve for regulating the throughflow quantity of the CO.sub.2 with an expansion nozzle, the valve being arranged inside the machine.

Abstract: Catalyst systems with a content of a platinum-group-metal catalyst, a co-catalyst, a quaternary salt and a base for the oxidative carbonylation of aromatic hydroxy compounds to the corresponding diaryl carbonates are obtained according to the invention as a residual melt by melt crystallization and can be returned into the carbonylation reaction or worked up to valuable materials. The melt crystallizate, which consists predominantly of diaryl carbonate and the parent aromatic hydroxy compound, is worked up to pure diaryl carbonate and pure hydroxy compound.

Abstract: A light valve modulator of reflective operation which includes a multi-layer structure which is controlled electrostatically, comprises a transparent substrate supporting a first transparent deformable layer and a second insulating dielectric deformable layer, with a mirror layer sandwiched between, and a third, dielectric insulating layer on the outside of the second layer, at least one of the layers between the second layer and the substrate being electrically conductive, and the third dielectric layer being capable of receiving an electric charge pattern by means of one or more electron beams, whereby the mirror layer is locally deformed by electrostatic forces occurring between the third layer and the conductive layer.The twin deformably layers allow good sensitivity, while the outside dielectric layer which receives charge from an electron beam protects the deformable layers from electron bombardment and the cathode from outgassing.

Abstract: Cogranulates of high bulk density which easily disintegrate in water and comprise aluminosilicates and crystalline sodium silicates having a layered structure. The aluminosilicates contained therein are those of the formulaM.sub.2/n O.Al.sub.2 O.sub.3. XSiO.sub.2. yH.sub.2 Oin which M is an alkali metal or alkaline earth metal, n indicates the valency of the cation, x is.gtoreq.2 and y has a value of between 0 and 8. The sodium silicates have an SiO.sub.2 /Na.sub.2 O ratio of (1.8 to 4.2):1. These cogranulates are prepared by mixing the pulverulent aluminosilicates and sodium silicates with one another and introducing the mixture into a zone in which it is compacted between two rolls rotating in opposite directions to form a compact. After comminution of the compact, the desired particle sizes are finally separated off from the oversize and undersize material. The cogranulates can be used in detergents and cleaning agents.
