Patent DE-2855170-A1 (DE)
Inventor: SCHLINSOG HANS-JUERGEN
IPC: B21D22/20
Filed: 1978-12-20
Abstract: This relates to the hydrophilization of metal surfaces and/or metal oxide surfaces. In the forming of sheet metal by drawing and wall ironing methods, in the past it has been necessary to provide lubricants so as to not only protect the metal, but also to hold down friction noises. The lubricants are difficult to remove and require expensive washing processes after the forming operation. It has been found that an hydroxide of the metal involved may be readily generated on the surface so that the surface is easily wetted by water, for example, and thereby conventional lubricants are eliminated.

Title: Blood sedimentation measured value determination - using rise of measuring curve at preset point of time after start of aggregation phase of blood
Inventor: SCHMID-SCHOENBEIN HOLGER PROF
IPC: G01N15/05
Filed: 1979-10-20
Abstract: The process uses the light transmittivity of a blood specimen for the measured value determination, as it changes in dependence of the erythrocytes aggregation. This photometric process can be based both on transmission and reflection. The obtained measured curve is called a syllectogram. The latter is determined after a sudden rest immediately after preparation of the blood specimen by centrifuginq. The rise of the syllectogram curve at a present point of time after the beginning of the blood aggregation ohase is taken as the measured value. Preferably the rise is determined 2.5 sec. after begin of the aggregation phase. Other time intervals may be used and the syllectogram curve may be digitalised at a frequency of 20 Hz. These values may be multipled by a factor, standardising the impinging light intensity.

Patent DE-3009463-A1 (DE)
Inventor: LEHNARD JAKOB
IPC: B32B1/02
Filed: 1980-03-12
Abstract: The conventional process of manufacturing hollow bodies with multi-layer walls using extrusion and blow molding techniques is improved by first making a preform of a thermoplastic carrier layer with an adhesive layer on one or both sides and then applying the additional layer or layers to the adhesive layer(s) in a separate operation. The additional layer(s) has properties different from the carrier layer and serves as an insulation or barrier layer to shield the carrier layer from substances to be contained by or which will surround the hollow body. Among other advantages, the improved process allows recycling of waste and surplus preform material, stronger heat-seal seams in the hollow bodies, less complicated extrusion equipment and more economic use of expensive barrier layer materials.

Title: Method for laying smoke screen using carrier projectiles - with first screen laid in close proximity to protected position, and further screens at increasing distances and heights
IPC: F41H9/06
Filed: 1980-06-14
Abstract: The vehicle to be protected, e.g. a tank (0), is equipped with projectiles for laying the screen, these being fired automatically when a warning device detects an electromagnetic beam identified as a threat from enemy sources. The angle of trajectory (alpha), is selected manually or automatically, dependent on the landscape contours. The first screen is produced at a distance determined by propellant charge and with the projectile fuse times (t1) to produce a burst at a chosen height, (4-8 metres). The second screen (2) is then laid at a greater distance e.g. 70 metres, with a longer burst delay (t2) and height of 8-15 metres. Finally, the third screen (3) is laid some 100 metres from the tank with a height of 10-20 metres. Thus three protective walls are formed by projectiles filled with chemical smoke producer, the pattern obtained by this method decreasing the time for forming such a screen-in many cases- a deciding factor.
