Title: Improvements in and relating to aircraft for high altitude flight
IPC: B64D13/02
Filed: 1931-06-11
Abstract: 365,961. Machines for high altitude flight; fastenings. JUNKERS, H., 21, Kaiserplatz, Dessau, Anhalt, Germany. June 11, 1931, No. 17008. Convention date, July 2, 1930. [Class 4.] Propeller driven aircraft for high altitude flight in which the spaces intended for continuous occupation are in the form of hermetically closed chambers have the axis or axes of the propeller or propellers outside the chambers, the propeller or propellers revolving in a plane or planes which do not intersect the chambers intended for continu o u s occupation. Fig. 1 illustrates a single-engined aeroplane having the engine 3 carried above the body in a hermetically sealed chamber 4 communicating with a hermetically sealed chamber 2 in the fuselage adapted to be maintained under positive pressure, the plane of rotation 5 of the airscrew being in advance of chambers 2, 4. Four-engined aeroplanes with tandem outboard engines have the tractor airscrews in advance of the fuselage nose and the pusher airscrews driven through long shafts so as to lie in a plane aft of the passenger chamber. A twin outboard-engined aeroplane is described having hermetically closed passages communicating with the chambers enclosing the engines. Where it is impracticable to arrange all propellers in the above manner, the chambers intended for continuous occupation may be divided and joined by hermetically sealed passages separated from the occupied portions by airtight doors, some or all of the propellers being arranged so that their planes of rotation intersect the passages. As applied to a fourengined machine, Fig. 4, chambers 15, 16 are joined by a passage 17 having doors 18, 19. Tractor propellers 24, 25 are in advance of chamber 15 and pusher propellers 28, 29 are opposite the passage 17. Means may be provided for indicating a loss of pressure in passage 17 which might be caused by fracture of propeller 28 or 29. Further, the doors may be arranged to open inwardly to the occupied chambers so that the difference in pressure may resist their opening and the difference in pressure may be utilized automatically to lock the doors. An automatic lock is shown in Fig. 5, wherein A is the passenger chamber, separated from a passage B by a door 30 normally maintained closed by a bolt 32. Should the pressure in B drop, the excess of pressure in A causes movement of a diaphragm 34 connected to a rocking lever 36 which causes a safety pin 38 to engage a hole 39 in the bolt 32 and thus prevent withdrawal of the bolt.

Title: High frequency heating system
IPC: H05B6/50
Filed: 1949-06-30
Abstract: 664,107. Automatic current, voltage control systems. RADIO CORPORATION OF AMERICA. June 30, 1949 [June 30, 1948], No. 17355/49. Class 38 (iv). A H.F. heating system comprises an oscillator circuit 5 coupled to a load circuit having a load 10 and adjustable condenser 12 which is adjusted in accordance with the current flow through the oscillator valve 18 or with the voltage across the load. The condenser is adjusted by a reversible motor 43 having one field winding 48 constantly energized in a sense to increase the R.F. power applied to the load and a second winding 47 variably energized through a thyratron 66 in a sense to decrease the R.F. power applied to the load. When the switch 17 is closed, R.F. is supplied to the load 10 and a relay 62 is energized thereby closing contacts 61 so that the field 48 becomes energized through a transformer 51 and series resistor 60 to adjust the condenser 12 for maximum power supply to the load. As the R.F. supply increases the current through the oscillator valve 18 increases thus increasing the voltage drop across cathode resistors 23, 24, a portion of the potential across either one of which is applied, via selecting switch 86 to the grid of the thratron 66 normally biased to cut-off by means of a transformer 72 and rectifier circuit 71. If the R.F. supply reaches a predetermined value the voltage applied to the grid of the thyratron causes it to conduct thereby energizing the motor field 47, overcoming the effect of the field 48 and causing the motor to adjust the condenser 12 to decrease the R.F. power applied to the load. When the apparatus is switched off the field 48 becomes de-energized, together with the biasing transformer 72, but since the transformer 51 remains energized the field 47 alone takes control of the motor and the condenser 12 is rapidly adjusted to the minimum R.F. supply position. In a modification, Fig. 3 (not shown), the voltage applied to the grid of the thyratron is the rectified voltage derived from the mid-point of two condensers connected in series across the load 10. If used for inductive heating the motor may control a variable inductance, Fig. 4 (not shown).
