Title: Incandescent light bulb with double enclosed filament - has double-walled glass bulb with evacuated wall cavity to reduce energy loss
Inventor: RUECKSTAEDTER HANS
IPC: H01K1/34
Filed: 1975-12-10

Title: Sleeve type gas filter - having spring loaded insert to support and tension bags
Inventor: MARGRAF ADOLF DIPL ING
IPC: B01D46/06
Filed: 1976-06-09
Abstract: Bag filter is divided by a partition into a dirty gas and clean gas section. The bags project through this and are sealed on the clean gas side.

Title: Offshore platform assembly - using guide ropes between base structure and deck structure during leg lowering operation
Inventor: MOLSBERGER HANS-GUENTHER ING G
IPC: E02B17/02
Filed: 1977-08-16
Abstract: Offshore structures are assembled from components prefabricated on shore and floated on site. A structural base component is first lowered to the sea bed. The platform of the top component is linked by ropes to the legs of the base structure to prevent any lift of the platform during the leg lowering procedure. Any occurring excess buoyancy is compensated by the flooding of ballast tanks in the legs which are being lowered from the platform. This simplifies the assembly of two-part structures on offshore sites. Impact damage of the legs during the lowering process by the action of swell and waves is eliminated.
