Abstract: An illumination device includes a housing a portion of which has a ball-like outer surface, a positioning base and an annular ring. The housing is arranged to accommodate a Light Emitting Diode (LED) and is at least partially transparent to wavelengths the LED is capable of emitting. The positioning base has a front side provided with an opening and is arranged to rotatably support the ball-like outer surface portion of the housing. The front side of the positioning base has a front surface with a recess. The recess is arranged to accommodate the annular ring in such a way that an orientation of the housing can be tightened.

Abstract: An arrangement for lighting an object having a first, non-mobile device (1) and a second, movable device (2). The first device (1) has at least one lighting unit (3) and at least one 5 rechargeable accumulator (4). The at least one accumulator (4) is connected to the at least one lighting unit (3) in order to be able to provide this with power. The second device (2) has a charger (5) for charging the rechargeable accumulator (4) of the first device.

Abstract: In a method for compacting a granular, loosely coherent mass, such as moist mortar, to obtain end products such as paving stones, kerbstones and the like, an installation is used which includes a vibrating table, a mold for the mass to be compacted, a stamp for pressing the mass into the mold, a hydraulic exciter and a hydraulic pressure element respectively connected to the vibrating table and the stamp, and a driver and a controller for controlling the exciter and pressure elements.

Abstract: An installation for compacting concrete mix includes a frame which has a lower plate and an upper plate between which concrete mix can be accommodated. The plates can be pressed in the direction towards one another and can be made to vibrate with respect to one another in order to compact the mix. Each plate is connected to the frame via an associated spring-mounted massive body.
