Title: Throughput fluoro-meter for low emissions with long delays - has partic. good excitation light suppression traps and optics
Inventor: KRAUSE HANS
IPC: G01N21/64
Filed: 1980-07-18
Abstract: The measurement sample is successively passed through a luminescence stimulation device (15) and a luminescent light detection and measurement device. Very weak emissions of luminescent light can be measured in liquids even in conjunction with long delay times.

Patent DE-3110507-A1 (DE)
Title: Recoil damper for long-barrelled weapons
Inventor: ZINSMAYER DIETER
IPC: F41A3/94
Filed: 1981-03-18
Abstract: The invention relates to a recoil damper for long-barrelled weapons, especially for hunting and/or sporting long-barrelled weapons. The object is, precisely when such long-barrelled weapons are used for hunting, to lessen the recoil and considerably reduce the danger of "deflection" of the shot, so as to spare the game in the hunting ground unnecessary torment and increase safety when the weapons are being used. Figure 9 shows a cross-section through a completely assembled recoil damper. It is essentially two box-shaped hollow bodies which are displaceable one in the other and which are filled with fluid and pressed apart by a steel spring arranged centrally on the inside. When the left-hand body is subjected linearly to a shock, this is absorbed, on the one hand, by the steel spring and, on the other hand, by means of the resistance which the viscous fluid generates, since it is pressed through the bores, located in the front side of the inner body, from the interior of the larger left-hand body into the smaller right-hand body when the two bodies are pushed one into the other. <IMAGE>

Title: Device for bending metal strips, bars, profiles and the like
Inventor: JACOBS HELMUT
IPC: B21D7/022
Filed: 1981-06-30
Abstract: The invention relates to a bending device (3, 4) in particular for extruded hollow profiles (1) made of light metal. It consists of a linearly guided pivot bolt (4) and, mounted thereon, a pressure piece (3) which has a plane contact surface (8) which bears against the secured but as yet unbent profile (1). The linear movement of the pivot bolt (4) perpendicularly to the as yet unbent profile (1) leads to a bending of the profile (1) around a curved circumferential region (7) of a stationary block (1), the contact surface (8) rolling progressively at the points of the profile (1) which are being bent. In this manner, bent spacer frames for insulating windows can be manufactured especially easily. <IMAGE>

Title: Process for producing thin ceramic plates
Inventor: ZIEGLER LIESELOTTE ING GRAD
IPC: C04B41/50
Filed: 1981-11-12
Abstract: In a process for producing thin ceramic plates, in which a liquid ceramic slip is applied to a water-permeable or absorbent carrier and then, together with the carrier, exposed in a firing furnace to the action of the furnace temperature, a mineral fibre mat stable per se is used as the carrier and the liquid slip is sprayed on until this carrier is fully saturated, in order to avoid the incorporation of a combustible carrier material for the liquid ceramic slip and to eliminate difficulties from the process sequence which arise as a result of using the liquid slip, the mineral fibre mat being impregnated with a wetting agent before the liquid slip is sprayed on, and an organic set-up agent and wetting agent being added to the slip. The impregnated mineral fibre mat can be decorated or used as a decorated mat.
