Abstract: A print head for a printer is constructed as an optical character generator and comprises a plurality of switch cells arranged in a two-dimensional field. The energy output by radiation source is transmitted in parallel onto the matrix dots arranged in a grid and these matrix dots lie in the plane of an ink layer on a band-shaped continuous carrier. Each of the switch cells comprises an optical switch element composed of a transparent ferro-electric ceramic substrate composed of lead, zirconate titanate doped with lanthanum and having transparent electrodes for applying a pulse-shaped controlled voltage. In response to a corresponding control voltage, the radiant energy is transmitted frm the switch element into the allocated matrix dot, for example, for a local melting of the ink layer on the carrier, which was coated with a thermo plastic printing ink having a low melting point. The printing arrangement is suitable for line printers having single colors or multiple color printing.

Abstract: Dans une installation pour la mise en valeur de l'énergie thermique, un fluide de travail est expulsé d'une première chambre de travail pendant la première partie d'un cycle de travail et poussé dans une deuxième chambre de travail où règne une température supérieure à celle de la première, puis repoussé pendant une deuxième partie du cycle de travail de la deuxième à la première chambre. De l'énergie thermique est fournie au fluide de travail pendant son passage de la première à la deuxième chambre et enlevée pendant son passage de la deuxième à la première chambre. Les chambres sont formées par les chambres de travail à volume variable d'unités de moteurs à piston déphasés (10, 12, 14, 16) couplés l'un à l'autre et reliés par des conduites de fluide (18, 20, 22, 24) de sorte que le fluide de travail soit expulsé d'une chambre de travail qui se rétrécit et qui a une température relativement élevée pour être poussé par une première conduite dans une chambre de travail à basse température qui se dilate, et qu'en même temps du fluide de travail soit expulsé d'une chambre de travail à basse température qui se rétrécit pour être poussé par une deuxième conduite dans une chambre de travail à plus haute température qui se dilate. Les unités de moteurs à piston travaillent dans leur ensemble à un niveau déterminé de température, de sorte que l'on peut éviter ainsi tout problème d'isolation thermique.

Abstract: The optical device serves for measuring the luminescence of surfaces of a sample with brightening elements dispersed throughout which generate luminescence or for the purpose of measuring colour on brightened samples such as textiles, paper, plastic, paints, varnishes or the like, as a result of the double measurement of the spectral reflection of the sample, one measurement with light with an ultraviolet portion and one without an ultraviolet portion, the sample being irradiated by a first light source at a specific angle and with a detector for receiving the light preferably reflected perpendicularly from the surface of the sample or with an angle deviating slightly therefrom. In this case a second light source is provided. The first and second light source irradiate the reference sample preferably at such an angle suitable for the 45/0 DEG measuring geometry, an ultraviolet filter and a plane beam divider and a second detector being provided between the two light sources, the first light source being constructed as a torus-shaped discharge lamp for pulsed light and a first aperture being located at a first distance in a plane parallel to the annular plane of the first light source, the first distance defining the first measuring geometry and the beam divider covering the entire cone envelope between the first light source and the first aperture, a second aperture being located in the mirror image of the first with respect to the beam divider and it being possible to position the sample at the point of one of the apertures, whilst a reference sample or the second detector for receiving reference light is located at the point of the second aperture. In addition, a shutter is provided for each light source, which shields the direct light incidence, of the said light source, onto the aperture on the same side as the beam divider and the second torus-shaped discharge lamp for pulsed light is arranged on the other side of the beam divider and parallel to the latter at a second distance which determines the second measuring geometry.
