Abstract: A process for thermally etching a CaAs substrate prior to molecular beam epitaxy comprises the steps of: heating the GaAs substrate to above 750 DEG C.- at which temperature both Ga and As are evaporated from the GaAs substrate- whilst irradiating it with an As molecular beam, thereby removing contamination adhering to the surface of the GaAs substrate. As the substrate evaporates it carries with it the contamination. The process can be performed by an apparatus comprising a prechamber (2), in which the surface is evaporated, connected to a growth chamber (6), in which an epitaxial layer is grown.

Abstract: The damping mechanism has a piston, sliding in a cylinder and dividing it into two chambers. The chambers are connected via non-return valves, acting in opposite direction, and via a variable assymmetrically adjusted damping valve. During a valve slide movement, the size of the opening for one flow direction decreases by the same amount, as it increases for the other flow direction. Thus when compared with an active damping system with external energy supply the damping force is reduced to zero value.

Abstract: A static converter circuit has a voltage summing transformer (Tr-Tr13) with several part transformers (Tr1-Tr13) the static-converter-side winding of which are connected via one four-quadrant actuator each to a direct-voltage link circuit. The four-quadrant actuators are single-phase bridge circuits with one GTO thyristor each and a diode, which is antiparallel thereto, per bridge branch. The static-converter-side windings of the part transformers can be short circuited in each case by means of an alternating-current circuit breaker with antiparallel-connected thyristors. Each part transformer has a separate core. The power-system-side windings of the power transformers are connected in series and are connected at their ends to a railroad power system with 162/3-Hz. The direct-voltage link circuit is connected via power-system-commutated static converters and a static converter transformer to a national power system with 50 Hz. For generating an approximately sinusoidal alternating voltage part voltages of equal amplitude which are supplied by the part transformers are added and/or subtracted step-by-step in the voltage summing transformer. Each thyristor of a four-quadrant actuator is turned-on and turned-off at the most, twice per period of the alternating voltage. This reduces power losses and expenditures for cooling the semiconductor components. The static converter circuit is suitable for frequency converters and reactive-power compensators.

Abstract: A technique is disclosed for the detection of cancer using nuclear magnetic resonsance (NMR). Specifically, NMR parameters for protons of lipid methyl and/or methylene groups are determined and compared against a corresponding value for healthy patients. In the preferred embodiments, an NMR spectrometer is employed in conjunction with a Fourier transformer to provide a spectrum for non-water components of blood, blood serum or blood plasma and the width of the methyl and/or methylene groups is measured at half-height as a determination of spin-spin relaxation time (T2) which is the parameter used for purposes of comparison with healthy controls. Suppression of the water proton signal is employed where necessary in order to obtain a suitable spectrum for the non-water component protons.

Abstract: The container has four longitudinal and transverse side walls which extend from a rectangular bottom to a widened rectangular opening. The container provides the possibility, on the one hand, of nested stacking in a space-saving manner in the empty state, but also, on the other hand, permits a secure and stable stack formation from several filled units. There are therefore provided two strips 17 which are hinged on in the manner of a flap in the region of the upper edges 6a of the transverse side walls 6, which strips can be folded from a swivel position, which exposes the rectangular opening up to the transverse side walls 6, to a swivel position which partially bridges said first swivel position adjoining the transverse side walls 6, and in which the distance between the mutually facing edges of the strips 17 is of smaller dimensions than the width of the container bottom between the transverse side walls 6. At their ends, the strips 17 bear bearing cheeks 16 which extend transversely to the longitudinal direction of said strips and are held swivellably in bearing blocks, arranged away from the corners of the container, at the upper edges of the longitudinal side walls. The strips 17 are received and supported in their exposing swivel position in a channel-type edge portion, which is open at the top, at the upper edges of the transverse side walls 6, whereas they are received and supported in their bridging swivel position with their ends and the bearing cheeks 16 in troughs 12, which are open at the top and towards the interior of the container, of edge portions of the longitudinal side walls. <IMAGE>

Abstract: The opposite ends of a printing plate for rotary printing are mutually joined together in order to produce a cylindrical printing plate which is capable of being mounted on to a printing cylinder, for example a printing cylinder where the diameter is capable of being enlarged. The join is made in such a manner that the photosensitive coating of the printing plate is removed at two end edges, that a right-angled bend bent round at the end is constructed at one end of the plate and that the other end, bent through 90 DEG , is set into the U- bend. The join can be made along a generating line of the cylinder or along a line angled to the generating lines of the cylinder. 
<??>The plate can be mounted with the bent edges directed radially inwards or these edges can be inclined to the cylinder radius. The space which is formed between the two adjacent right-angled bends of the end edges of the printing plate is filled with curing material. In this way, a join is produced which forms a continuous smooth surface for the printing plate in the circumferential direction. The filling material can be removed after the printing plate has been used, thus enabling the printing plate to be stored flat. Alternatively, the join of the plate ends can also be made permanent by introducing an adhesive between the right-angled elements in order, thereby, to create a permanent join in the axial direction.

Abstract: To avoid a delay in the braking action when a loom is stopped, especially with a combined brake/clutch between the drive and loom main shaft, the switch action to interrupt weaving is selectively on a weft break between the supply bobbin and the wound w store in the feed system when an electrical signal is generated, or when another criterion at the program control is achieved. The other criterion at the program control is a given number of weft insertions without a break in the weaving, or continuo uninterrupted weaving for a given time span. The switch action to stop the loom is effected when the first criterion in the prog control generates an electrical signal. Or the loom stop switch is triggered exclusively on an electrical signal showing a weft break between the supply and feed points.
