Title: Insulation and thermal regulation of building - using sealed inter-wall spaces which may be evacuated or filled with conductive fluid to regulate heat transfer
Inventor: IVORRA CLAUDE
IPC: E04B1/74
Filed: 1982-03-24
Abstract: A vacuum is used in spaces between exterior and interior walls of a building to insulate the building. Variation of the rate of heat transfer from the building, in order to regulate its interior temperature, is obtained by variation of the level of vacuum in the wall space. The rate of heat transfer can be increased by injecting a fluid under pressure into the cavities, providing a thermally conductive path across the spaces. The vacuum pump (8) and fluid pump (9) are controlled by regulators (10, 11, 12) which monitor interior temperature and ensure it remains at the preset value. Similar units can be fitted in the roof space.

Patent FR-2505436-A1 (FR)
Inventor: REINHOLD LOTHAR
IPC: B21D24/02
Filed: 1982-05-05
Abstract: The invention relates to a pressure-limiting valve for hydropneumatic drawing cushions on presses. The invention is intended to ensure a constant cushion force over the entire working range with a low outlay on control. The object consists in avoiding the occurrence of pressure peaks at relatively high working speeds by multistage control of the control piston and by the arrangement of channels and spaces with favourable flow properties for the pressure medium. According to the invention, this is achieved by the fact that the valve insert consists of separate sealing cones (8) guided over one another and of main control pistons (5) and a pressure piston (10) is arranged on the sealing cone (8) via a taper. The sealing cone (8) is provided with a control channel (3) acting as a connecting element between the separation surface and the oil space (4) and is connected to the auxiliary control piston (7) via a piston rod (9). The main control piston (5) is guided in axially displaceable fashion on the piston rod (9) of the auxiliary control piston (7).
