Title: Channel pane heat insulating double glazing - with outer frame of plastic blocks holding pane shank end apart
IPC: E06B3/54
Filed: 1975-05-13
Abstract: The insulated glazing is achieved by similar panes, of U-shape in cross-section, fixed in an outer frame shaped section with their shaped openings facing each other in pairs. The outer frame shaped-section (10) is made up from identical section building blocks (11) joined to each other in a row, and made of pref. plastic heat-insulating material, or at least with exteriors of this material. Each of these has a bearing surface (12) inside projecting fitting surfaces (13), holding in position the stem (5) and arms (6) of two interfacing U-sectioned panes, from above and below. This is done in such a way that an interval is left between the arm ends (8) of the panes (1). The heat insulating effect is improved, with no parts of the heat-conducting material on one side in contact with similar parts on the other.

Title: Load limiting mechanical coupling for electrical rotor - uses bolts designed to fracture at specified torque leaving only elastic coupling
Inventor: UTECHT MANFRED DIPL ING
IPC: H02K1/28
Filed: 1976-11-18
Abstract: The application is principally to variable speed ac motors where the applied variable frequency may, in certain circumstances, set up undesirably high oscillatory torques in the shaft system. To protect the mechanical parts against the high stresses which could result the solid coupling between the rotor hub (1) and the shaft (2) is made by means of special bolts (13) designed to fracture at a predetermined torque in excess of the full load value. When the bolts fracture the coupling is maintained by an elastic drive employing bushes (3) of an elastomeric material. The resulting change of natural frequency helps to damp out the oscillations with minimal damage to the rotor. The fit between hub and shaft is typically very light.
