Title: Giant pulse laser with narrow bandwidth emission line - has main resonator bounded by two reflectors, containing system components
Inventor: LANG RUDOLF S DIPL PHYS
IPC: H01S3/11
Filed: 1973-06-20
Abstract: The auxiliary resonator is bounded by the two reflectors of the main resonator and by third reflector located outside the main resonator. The polariser is so arranged in the main resonator, w.r.t. the polarisation rotator and the laser medium, that radiation in a first polarisation direction is passed without substantial influence. The radiation in the second polarisation direction is reflected out from the main resonator and to the third reflector over an auxiliary radiation path, containing a restrictor of the optical bandwidth of the auxiliary radiation. From the third reflector the radiation is projected back to the polariser, deflecting it to one reflector of the main resonator.

Title: Concrete wall formwork - panel connections through holes in frames within area of bracing beam
Inventor: MARKEWITZ WOLFGANG
IPC: E04G11/10
Filed: 1973-08-21
Abstract: Adjacent shuttering panels, with peripheral reinforcement frames and intermediate parallel reinforcement bearers, are joined, where they meet, by means of corresponding holes in the area between the reinforcements, and the frames would normally need to be substantial because of the bending stresses involved when several panels are joined at an angle. The reinforcing bearers are preferably shaped iron bars, with stems or arms fitting against arms or stems of frames of the same material. The connecting elements can be bolts through the holes, with a head at one end and a recess at the other, with a U-shaped wedge with one arm at least engaging in a recess. Bending stresses are reduced, and reinforcing frames can therefore be of lighter construction.

Title: Yarn dyeing machine - has hinged hank carrier rods which swivel open for loading or unloading
Inventor: LEIBIG RUDOLF
IPC: D06B5/20
Filed: 1975-01-15
Abstract: In appts. for dyeing yarn in hank form, a yarn rod holder (2) for placing in a circular treatment vessel has curved yarn rods on which the hanks are hung. The curved rods are hinged and can be swivelled at one end. The curved yarn rods form concentric circles. The rods, which radiate outwards from the central rod holder can be connected together with the neighbouring rods opposite to them. The yarn rod holder consists of a central tube with upper and lower sections which are movable in relation to each other by means of a screwed spindle. On each of the upper and lower sections arms are arranged to carry the hinged ends of the hank rods. The distance between the upper and lower rods is adjusted to correspond with the length of the hank. The free ends of the hank rods are arranged to be coupled together by one end having a series of grooves and the other end a ball-housing. This quick locking device has a locking length of about 180mm which makes possible the necessary re-arrangement of the hanks before final closure. The hank rods are not all the same length whereby the locking points are staggered with each other. This offset corresponds to about half the width of hank so that a number of hanks always fill up a rod with their width and no unfilled areas remain. Uniform colour take up is ensured.
