Title: High-frequency plasma drive
IPC: H05H1/46
Filed: 1975-11-05
Abstract: 1521327 Jet propulsion plant  MESSERSCHMITT-BÍLKOW-BLOHM GmbH 5 Nov 1975 [16 Nov 1974] 45940/75 Heading F1J [Also in Division H1] A high frequency plasma drive comprises a “ # high frequency generator 7 coaxially coupled to a “ # resonator 8 which forms part of an open ended discharge chamber 11 in which a uniform magnetic field is produced by coil 15 and in which propellant gas is ionized and the plasma subsequently accelerated, wherein the intensity of the magnetic field in the discharge chamber, the frequency of the generator and the density of the plasma are so arranged that the dielectric constant of the plasma is negative whereby Lorentz forces acting on the plasma are subject to resonance-like intensification. As shown, the generator and discharge chamber are formed by coaxial tubes 2, 3 inter-connected by a disc 4, all of silver plated copper, the generator 7 being energized by a planar-triode 5 through an isolating capacitor 6. The cylindrical cavity circuits i in the generator and resonator interconnected through an inductive coupling loop 9. Mercury vapour is introduced through a distributer 12 into the discharge chamber 11 which is closed at one end by a quartz disc 10. When drive is put into operation the gas discharge ignites in the electrical field of the resonator without a special ignition device and the plasma is accelerated from the chamber by Lorentz forces. The mechanism of this acceleration and the factors influencing it are theoretically discussed in some detail. In a modification, Fig. 2 (not shown), a quartz plasma boundary anchor (21) followed by acceleration and retardation electrodes (22) is provided at the open end of the resonator to accelerate the ions, which may be neutralized by electrons from an axially disposed hollow cathode (23). The current density may be varied by means of the intensity of the magnetic field.

Title: Refrigeration compressor systems
Inventor: WILL PAUL
IPC: F25B31/00
Filed: 1967-10-10
Abstract: 1,202,384. Controlling compressors. MASCHINEN UND APPARATEBAU SCHKEUDITZ VEB. Oct.10, 1967, No.46269/67. Heading F1N A refrigerant compressor 1, when in-operative, is isolated from its inlet line 8 and outlet line 10 by suction and discharge shut-off valve 7, 9 which open when the pressure of the compressor's lubricant in a line 17 reaches a predetermined value. The valves 7, 9 are shown in their unloaded positions corresponding to the compressor being stopped or just started. When first started the compressor's output is returned to the inlet line 8 through the valves 7, 9 and a bypass line 36. As the lubricant in the line 17 increases in pressure, a piston 39 in the valve 7 is depressed so that a rod 40 moves to open a pilot valve 41, 55 of the valve 7. The opening of the pilot valve collapses pressure in a control chamber 34 connected by a line 32 to the outlet line 10 upstream of the discharge shut-off valve 9. Hence the rod 40 continues to move, overcoming the spring 29, and thereby causing opening of the main valve member 26 of the valve 7 to open the inlet line 8. A large diameter portion 43 of the rod 40 closes the by-pass line 36 and the final movement of the rod 40 causes a member 56 to close connection of the control chamber 34 to the outlet line 10, and hence the chamber is maintained at suction pressure. Thereafter pressure is builtup in the outlet line 10 by the compressor 1, thereby opening the discharge valve 9 against a spring 30. The reduced pressure in the control chamber 34 is communicated by a control line 35 to a chamber 46, thereby to cause opening of a valve 11 and allow oil to return to the compressor through a line 24, 25.

Abstract: 1372079 Sawing chipboard webs to length J KOSTER [trading as WILHELM MENDE & CO] 11 Oct 1971 [30 Oct 1970] 47323/71 Heading B5L Apparatus for sawing into lengths a chipboard web 1 comprises means for driving the web via a slipping clutch, a sawing mechanism 7, a ram 6 for stopping the web in position for the sawing off of a length by the sawing mechanism, a stop 10 located downstream of the mechanism 7 for abutment by the leading edge of the web, a switch 11 located upstream of the stop actuable by the leading edge of the web, and a time delay mechanism 13 adapted to actuate the ram 6 and subsequently a device 17 for withdrawing the stop 10, the switch being arranged to set in operation the time delay mechanism before the chipboard edge reaches the stop.  In the apparatus shown, the web 1 is advanced by a belt 2, a driven roller 3 and pressure roller 4, and a belt 9, over a table 5 until its leading edge is sensed by a feeler 12 of the switch 11. The switch actuates the time delay mechanism 13 which causes the ram 6 to press the web against the table 5 after the leading edge of the web engages the stop 10. During this time belts 2, 9 and rollers 3, 4 slip on the web. . The mechanism 13 then causes a device 8 to lower the sawing mechanism 7 into the web to cut off its leading portion. The mechanism 13 then causes a device 17 to raise the stop 10 and then raises the mechanism 7 and ram 6 so that the cut portion and the web may again advance. The belt 9 is driven faster than the belt 2 so that the stop 10 can be repositioned after passage of the cut-off length.
