Title: Window case with screw fixture - has pressure applied towards exterior with barbed bends facing tongue and screw on pressure units
IPC: E06B1/60
Filed: 1977-03-02
Abstract: The window case has elements which exert pressure from the interior side, from the inserted blind frame onto the exterior sealing system, under screw action effecting simultaneous independent transverse closing with progressive tension of the frame shanks towards the case. The pressure elements (1) are equipped with bent sections (2) with an acute-angled barb facing the internal surface of the case shanks (6). On the opposite side, facing the outside of the blind frame (9) the elements have a bent-sectioned tongue shank (3), with a profile matrix (4) set on it, and a threaded screw (5) acting towards the exterior. This allows pressure elements to be inserted from the building interior, between frame and case, after frame insertion, with exterior sealing effected by screw pressure.

Title: Mechanised plant sorting machine - has pincer-like holders interacting with conveyor belts, points and delivery tables
Inventor: ROSENTHAL UDO
IPC: B07C5/12
Filed: 1977-03-25
Abstract: The mechanical sorting appts for grading plants such as roses etc. has two guide tracks (11, 12) connected together at points (13) and mounted on a support frame (10). In the area of the delivery tables (22) for the sorted roses, the guide tracks have one belt nearer the tables and one further away. The guide tracks have conveyor units (14, 15) with pincer-like holders for the articles. The pincers run into a slit in the delivery table (22) so that the table is beneath the roses. Since the conveyor unit (15) during its path beneath the delivery table (22) is always remote from it, the rose is removed from the pincers and rolls to the deepest point on the delivery table. At the end of the outer guide track the pincer then returns on the inner guide track and passes back to the leading station. The points guide the conveyor units to the specific delivery table which is selected according to the length or thickness of the plant stem.

Title: Pressurised water reactor steam outlet pipework - has bending strength modulus of weld connections around main valve greater than in connecting pipework (BR 26.9.78)
Inventor: LAURER ERWIN
IPC: F22B37/44
Filed: 1977-09-09
Abstract: The body of the main fast closing valve on the steam outlet of a pressurised water reactor is connected to several supplementary valves. These connections are weld connections and the supplementary valves have pipework runs on their downstream sides. Each supplementary valve and system has a nominal dia. less than that of the main valve. The bending strength modulus of the connections of the supplementary valves to the body of the main valve is at least twice the modulus of pipe connections downstream of the supplementary valves. Pref. the relationship of bending strength modulus of the connections to the main valve to that of downstream pipe connections is 4 to 10 times greater. The pipes downstream of the supplementary valves are surrounded by an outer-pipe as far as the closest wall. These outer pipes are attached to the bodies of the supplementary valves in an articulated way. The arrangement avoids great stresses in welds close to the reactor.
