Title: High pressure discharge lamp
Inventor: IIDA TAKENOBU
IPC: H01J61/54
Filed: 1983-08-22
Abstract: A high pressure metal vapor discharge lamp contains in an outer bulb 8 a starting circuit 6 connected in parallel with a light emitting tube 1 having at least one pair of main electrodes 2a, 2b. The starting circuit 6 includes a ceramic capacitor 5 exhibiting a non-linear voltage-charge characteristic and a voltage-sensitive semiconductor switching device 4 to generate starting pulses. A thermosensitive switch 18 disconnects the starting circuit 6 when the lamp has warmed up. A diode 7 may be connected in parallel with the device 4 to increase the voltage of the starting pulses, and a resistor 16 may be connected in series with the diode 7 to delay charging of capacitor 5 so that a starting pulse is generated at every second to fourth cycle of the A.C. supply 11. The tube 1 may have an auxiliary electrode (13), (Figs. 7, 8), or a proximity conductor 15 to assist starting, a thermosensitive switch, which may be the switch 18, being used to disconnect the conductor 15 from the main electrode 2b after starting. The switching device 4, capacitor 5 and diode 7 have protective glass coatings. The capacitor 5 may have a dielectric formed from a mixture of barium titanate, barium zirconate, strontium titanate and calcium titanate. <IMAGE>

Title: Demountable ceiling
Inventor: FRIDH LARS GORAN
IPC: E04B9/28
Filed: 1987-02-09
Abstract: Boards (6) carry two metal strips, one 8 with a backwardly bent edge mounted inwardly of the edge of the board and overlapping one of the flanges 5 of a T-beam and the other 7 mounted overlapping the board edge and the other flange 5 in the mounted position of the board. It is thereby possible to displace the boards inwardly of the structure and to take them down according to requirements without any need of tools. The structure will allow the mounting of an additional insulation layer on top of the boards 6. At the same time the structure will appear as plane ceiling surface ie. with concealed support profiles 4,5. 
<??>With a view to being able to stack the boards 6 the strips 7,8 are so short that the strips are clear of each other and the boards, back to back, are turned 90 DEG  in relation to each other since the strips will then support the boards 6 evenly.

Abstract: When a circular cylinder, 1, is rotated in front of a semi circular cylinder, 6, the air around the circular cylinder, 1, and the air in front of the semi circular cylinder, 6, moves round and round, and the static pressure of the air falls. The air behind the semi circular cylinder, 6, does not move and its static pressure remains high and does not fall. The low pressure in front of and the high pressure behind the semi circular cylinder, 6, are said to give rise to a force which pushes and propels the semi circular cylinder, 6, with any loads attached to it upwards and in any direction. The force is said to be able to turn an electric generator or to provide lift for a personal flying harness (Figs 15-18) or a VTOL passenger aeroplane (Figs 22-25). <IMAGE>
