Abstract: A light diffuser, consisting of a holding mechanism and, releasably connected thereto, an inflatable sack that is at least partially translucent. The holding mechanism comprises an adapter ring that at one end serves for attachment to a spotlight and at the other end as a receptable of the sack. The adapter ring is closed off at the attachment end so as to be translucent and pressure sealed. At the holding mechanism means are provided for supply of a gaseous filling medium. Arranged at the adapter ring are a compressed-gas connection and an electronically actuatable valve for the gas supply, such that a first pressure sensor determines the increasing of pressure within the sack fixed to the ring and sends a switch-off signal to the valve when a preset maximal pressure value has been reached, in order to terminate or interrupt filling automatically.

Abstract: A process for producing multilayered microparticles for marking and later identifying substances or objects of any desired type, even animals and plants, has the following steps: several marking layers are successively applied in the liquid state onto a web-shaped or sheet-shaped substrate, each layer being dried and/or hardened before the next marking layer is applied, until a stack of layers of the desired type and in the desired order is obtained; the substrate is separated from the stack of layers; and the stack of layers is crushed into multilayered microparticles without affecting the integrity of the series of marking layers. A first disclosed process is characterized in that the individual marking layers are applied by a printing process. Alternative processes are characterized in that the individual marking layers are applied by bronzing, by spray painting or by roll coating.

Abstract: An ink jet printer with a piezo printing head (19) ejects lactate ink onto an uncoated printing medium (16) within the area of a surface to be imprinted. A preheating area (21) for preheating the printing medium (16) from its side opposing the piezo printing head is connected upstream of the surface to be imprinted, whereby the preheating area (21) can be adjusted to a temperature from 24° C. to 50° C. depending on the type of material and its thickness and/or the transport speed of the printing medium (16). There is an after-heating area (22) for drying the lactate ink applied to the printing medium (16) connected downstream of the surface to be imprinted from the side of the printing medium (16) opposing the piezo printing head (19). The surface to be imprinted is thermally insulated from the preheating area (21) and the after-heating area (22) so it is thermally decoupled from the heating of the preheating area (21) and the after-heating area (22).

Abstract: A punching, stamping rivet has a frustum-shaped rivet head and a shank following thereafter. In order to create a rivet connection between two adjoining structural parts, the shank is punched through the structural parts forming a punched hole, and a groove is coined thereafter around the shank end in that structural part. In order to be able to process structural parts having varied thicknesses, several shank grooves are arranged on the shank, into which shank grooves material penetrates under plastic deformation during the coining of the groove.

Abstract: A printable sheet of material for a printing machine allows smooth entry into a printing machine and firm grips by transport rollers. The printable sheet has impressions or perforations at the end portion from which the printable sheet is inserted to the printing machine. The impressions or perforations provide reduced stiffness thereby allowing papers with heavy weight to be used in a printing machine.
