Title: Laserbearbeitungsvorrichtung
Inventor: MAYER HANS JUERGEN
IPC: B23K26/06
Filed: 2003-01-07
Abstract: Die Erfindung schafft eine Laserbearbeitungsvorrichtung (100), mit der in einem einzigen Bearbeitungsprozess zwei voneinander unabhängige Laserstrahlen (110, 120) auf das gleiche Bearbeitungsfeld gelenkt werden können. Dies wird ermöglicht durch die Verwendung eines zumindest teilweise reflektierenden optischen Elements (130), welches derart ausgebildet ist, dass der erste Laserstrahl (110) im wesentlichen transmittiert wird und der zweite Laserstrahl (120) im wesentlichen reflektiert wird. Die Strahlengänge der beiden Laserstrahlen (110 und 120) werden vor dem Auftreffen auf das zumindest teilweise reflektierende optische Element (130) unabhängig voneinander durch zwei Ablenkeinheiten (111 und 121) variiert und mittels zweier Planfeldoptiken (F. Theta Objektive) (112 und 122) fokussiert.

Title: Light-weight concrete prepn - with hydraulic binder having reduced viscosity
IPC: C04B40/00
Filed: 1970-04-25
Abstract: Light-weight concrete is prepd. from light-weight fillers, esp. foamed synthetic resin particles or expanded clay, and a hydraulic binder prepared by mixing cement with a small amt. of water and imparting adhesive properties to the mixture by applying high flow speed and/or high pressure, as in DT. 2017647.

Patent DE-2336272-A1 (DE)
Title: Storage vessel for liquified gases - having double wall with powdered filling and flexible section in middle
Inventor: WALDMANN HANS DIPL ING
IPC: F17C3/02
Filed: 1973-07-17
Abstract: Vessel for storage of low boiling pt. liquefied gases has an inner vessel and outer vessel. The liquid is held in the inner vessel. The space between the two is filled with a powdered insulating material. Suspended in the centre of this is an elastic layer, supported on brackets fixed to the outer vessel. The elastic pocket is connected to gas lines and valves and it has a gas proof cover. Relative movement between inner and outer vessels is compensated for by the elastic layer. It is better to have the layer spaced in the centre because if it is in direct contact with the inner vessel, ice forms on it and it loses its flexibility. If a leak should occur in the inner vessel, moist air can be pumped into the elastic layer. Ice then forms and prevents cryogenic liquid reaching the outer vessel which is not capable of withstanding icy low temps. A glass wool mat is a typical elastic component.

The difference in shrinkage between the unfired ceramic layers and the layers e.g. of conducting material printed on these, is eliminated so that deformation of the sintered structure is prevented.

Title: Ammunition round for rifled gun - has separable base held to casing by pins and separated from it by ejection charge which explodes after shell leaves gun muzzle
Inventor: PROCHNOW JUERGEN DIPL-ING
IPC: F42B30/00
Filed: 1973-08-24
Abstract: The ammunition round is stabilised in flight by rotation and after firing it separates from the casing which has the copper belt engaging the rifling in the gun barrel. The base of the shell is releasably connected to the end of the casing by radial pins, whose diameter is such that they transmit the rotary acceleration received by the casing during firing reliably to the shell. The bores for the pins are near the end of the casing so that on firing of the ejection charge, to separate the floor from the casing the material of the casing between the bore and the end of the casing is torn out and/or displaced by the pins. Separation is easily achieved with only a small ejection charge.
