Title: Reactor control rod arrestor - friction pads or segments arranged circumferentially around the rod within a cylindrical housing
Inventor: MUEHLHAEUSER OTTO DIPL-ING
IPC: G21C7/12
Filed: 1970-12-04
Abstract: The segments are tapered on the outer face and when moved upwards by spring pressure grip the rod by virtue of the wedging action of the tapered face acts against a corresponding taper on the inner face of the housing. Thrust roller races between the faces inhibit binding.

Title: Herbicidal and miticidal carbamic acid esters
IPC: A01N43/34
Filed: 1971-01-19
Abstract: Herbicidal and miticidal carbamic acid esters. Cpds. of general formula (I): (where X is -O or methylene; Y is -O or -S; R1 is H or alkyl; R2 is alkyl or cycloalkyl; or R1 + R2 + N form a heterocyclic ring; n is 1 or 2) have herbicidal and miticidal activity.

Title: Shuttering for sinking of deep shafts - has stiff frames with internal guides and smooth outside walls for stacking into shaft
Inventor: METZLER WILHELM MATHEUS
IPC: E02D17/08
Filed: 1973-10-12
Abstract: The shuttering system used ensures that the excavating equipment can continue working without any appreciable waiting times. The shuttering elements do not have bracing components. The shuttering sections have internal brackets which project above the upper edge of the shuttering frame and the ends of these brackets are bent inwards. Similar frames are stacked and the brackets form stabilising and centering elements. These brackets ensure that the stacked sections are centered in all directions correctly and that the sections rest correctly on the edges. The excavator digs through the shuttering frame and from time to time the scoop is used to tap against the upper edge of the upper frame for lowering it into the excavated hole. After the first shuttering unit has been hammered below the surface the next section is put on top of it and the excavation continues. The shuttering frames are lifted into position by internal handles.
