Abstract: A method of investigating a solid sample, in particular a geological sample, such as a borehole core sample, includes the steps of positioning the sample on a sample support device, positioning a hyperspectral camera device, so that a line-shaped surface region of the sample is covered by a field of view of the hyperspectral camera device, illuminating the sample on the sample support device, moving the hyperspectral camera device and the sample support device relative to each other, wherein the field of view of the hyperspectral camera device is moved along a scanning direction over the surface of the sample, and collecting a hyperspectral image of the sample during the moving step, wherein the hyperspectral image is composed of multiple hyperspectral line images.

Abstract: The invention relates to an axial piston machine (1) comprising a housing (2) in which a drive disk (7) and a cylinder block (12) axially disposed next to it are received so as to be rotatable relative to each other about longitudinal center axes (11, 13). These axes run obliquely at an angle (W1) relative to each other in an oblique axis plane (E). A cam disk (18) is disposed on the front of the cylinder block (12) facing away from the drive disk (17) and is supported on the housing (2) by means of a positioning device (19) with positively engaging positioning elements (19a, 19b). A guide element (21) having a guide center axis (22) running coaxially to the longitudinal center axis (13) of the cylinder block (12) is disposed on the side facing the cylinder block (12).

Abstract: In a method for operating a gas turbine centre in the vicinity of the group nominal full-load conditions, the cooling of the working fluid before and/or during the compression is set in such a way that the respectively attainable full-load power is above the current power. Rapid power demands can therefore be rapidly satisfied by an increase in the turbine inlet temperature or by opening an adjustable inlet guide vane row, whereas the control of the cooling effect, which has a tendency to be more sluggish, is employed to adjust the full-load operating point.

Abstract: An ink ribbon for a printer or the like has a leading and/or trailing, optically operative control strip. The control strip has only a first light-impervious or opaque control portion and a second transparent control portion. The control portion adjoining the ink ribbon is of a length of between 1 and 4 cm.

Abstract: The invention relates to an axial piston machine having an oblique disk body (14) arranged in a housing (1) in a torsionally secure manner, having a drive shaft (4), which is mounted in the oblique disk body (14), and having a rotatable cylinder drum (7), which is coupled with the drive shaft (4) and in which a plurality of pistons (9) may be displaced axially in piston bore holes, their piston heads (11) being supported by means of sliding shoes (12) against the oblique surface (13) of the oblique disk body (14). The purpose of the invention is to construct the axial piston machine in such a way as to make possible torsional securement of the oblique disk body (14) which is simple in terms of production techniques and assembly, with a compact constructional form. This is achieved by mounting the oblique disk body (14) with its peripheral surface (16, 17) torsionally secured in a form-locking manner in a recess (19) of the housing (1) shaped to correspond to the peripheral surface (16, 17).

Abstract: In a device on hoisting machinery for automatically controlling the movem of a load carrier and for steadying the pendulum-type motion of a load suspended from the load carrier, a signal transmitter is provided for controlling the movement of the load carrier traction motor by means of a selected substantially cosine-shaped load carrier acceleration signal (b.sub.K). In such control a reduction is obtained of the acceleration time interval and braking time interval (T), respectively, at a selected maximum pulling force of the load carrier traction motor, and it is possible to keep the pulling force constant. The load acceleration (b.sub.L) follows a cosine curve.

Abstract: A hydraulic dredge for recovering manganese nodules from the sea bottom includes a transfer station suspended from a mother ship at a fixed depth from the surface and a dredging tool assembly suspended from winches on the transfer station by means of cables whose effective lengths are varied in response to depth signals from sensors respectively associated with the cables on respective parts of the tool assembly to keep the same contiguously adjacent the sea floor surface in parallel relationship.
