Title: Method and apparatus for furnishing microwave energy
Inventor: HOFFMANN TIBOR
IPC: H03C3/36
Filed: 1960-01-26
Abstract: 946,219. Masers. TAVKOZLESI KUTATO INTEZET. Jan. 26, 1960, No. 2856/60. Heading H3B. Polarized light, which may be visible, ultraviolet or infra-red is used for pumping in a maser. The maser is used for the generation, amplification or frequency modulation of microwaves. The energy levels of the working substance are slit by a magnetic field. In the embodiment described, the Lyman-α line of the hydrogen spectrum is used to pump electrons of atomic hydrogen to the energy level 2<SP>2</SP>P3/2, m=¢, Fig. 5. A resonant cavity in which the hydrogen is irradiated is tuned to the frequency (9000 mc/s.) generated when the electrons fall back to another level 2<SP>2</SP>S1/2, m=¢ in a field of 2000 gauss. The transit of electrons may be stimulated by a microwave of 9000 mc/s. which is thereby amplified. The maser may generate a continuous output stimulated initially by a random oscillation of 9000 mc/s. The magnetic field can be varied to modulate the frequency of the output. Apparatus.-Hydrogen at a pressure of 10 mm. of mercury is circulated in a glass tube 17 of approximately rectangular configuration. The circulation is induced by a cooling jacket 22. Electrons emitted by a thermionic cathode 19 are attracted by an anode 18 in the form of a grid at a potential of from 8 to 11.5 volts above the cathode. The energy gained by the electrons is sufficient to dissociate the molecular hydrogen which they encounter. Atomic hydrogen flows through the cavity 10 in a metal body 11. A constriction 21 in the glass tubing increases the speed of flow. Within the cavity 10 a T-junction is formed in the glass tube 17, the " pumping " light being transmitted down the main limb 23 of the T containing hydrogen at 10<SP>-4</SP> mm. Hg. A hydrogen discharge tube 28 directs light on to a polarizing mirror 31 of lithium fluoride at an angle of incidence of 63Œ 1 degrees. This angle is chosen so that the light in the Lyman-α line is plane polarized and directed along the limb 23 into the cavity 10. The limb 23 is sealed off from the cavity 10 and from the discharge tube 28 by lithium fluoride windows 29, 30 which transmit the Lyman-α line. Probes 26, 27 serve as input and output terminals for the signal to be amplified and the amplified signal. A Fresnel rhomb 42 of lithium fluoride may be fitted in the limb 23 if circularly polarized light is required.

Abstract: 525,818. Ice-making. SHORT, F. Jan. 28, 1939, No. 3034. Convention date, Jan. 29, 1938. [Class 29] A thick layer of ice is formed on a cylindrical surface 10 and is removed in narrow strips by a cutter 11 movable radially to impart a relatively slow powerful compressive force at a distance from the free edge of the layer to push a strip tangentially along the surface. The ice is formed in two layers S of increasing thickness with open spaces between the vertical edges of the layers, and is removed. from the thick edges by serrated blades 11 with wedge faces disposed on the side at which the ice is to be removed. After one vertical strip of ice has been removed the blades are withdrawn and rotated towards the thin ends of the sheets through a distance equal to the desired width of the strips. The cylinder 10 is surrounded by a jacket 30 to which refrigerant is supplied by a pipe 31, and the water &c. to be frozen flows through spaced holes 14 in an annular tank 15 on to a rubber block 87 and thence to the cylinder wall. The holes 14 are widely spaced in the regions where ice is being removed so that the ice is supercooled and dry, while a greater volume of water is supplied to the thin ends of the sheets by closer spacing of the holes in these zones. Excess water flows into an annular trough 19 whence it is returned by a pump 20 to the tank 15. Each blade 11 is carried by pairs of spaced links 51 connected by links 54 to shoulder blocks 56 rigidly secured to a hollow shaft 16 mounted in bearings 40, 41. The inner ends of the links 51 are connected by pins 57 to a thrust rod 58 disposed within the shaft 16 which is slotted at 59 for passage of the pins 57. At its upper end the thrust rod 58 is rotatably connected to a lever 66 operated through an adjustable link 70 by a motor 73. The hollow shaft 16 is rotated intermittently when the blades are in the retracted position by a ratchet disc 77 rigidly secured to the upper end of the shaft and turned by a pawl on a rod 79 reciprocated by an arm 83 secured to the shaft 67 of the lever 66. Adjustable stops 84 on the rod 79 enable the stroke of the pawl to be varied to alter the width of the ice strips removed by the blades. It is stated that the apparatus may be employed for the removal of material dried or baked on a surface.

Abstract: 974,591. Bottling. VICKERS-ARMSTRONGS (ENGINEERS) Ltd. Jan. 22, 1964 [Jan. 24, 1963], No. 3087/63. Heading B8T. A rotary counter-pressure filling machine with a number of filling heads disposed around an axis of rotation, has each head comprised by a valve body 3 within an annular pressurized liquid tank 4 concentric to said axis, the valve body having fluid passages 6, 7, 8 extending therethrough and controlled by separate valves 13, 20 operated in timed relationship against spring influence by a drum cam 27. The latter is rotatably mounted on top of the body and is turned by a spring-influenced lever system 30, 33, 34 pivotally mounted in the wall of the liquid tank and actuated by a circular cam track surrounding the machine. Liquid flows from the tank into the passage 6 through ports 9 and passes into the vessel, e.g. bottle, to be filled via a poppet valve 13 urged closed by a spring 18 and opened by a plunger 16 actuated by a track on the drum cam. Counter-pressure gas from the tank is fed to the bottle through passage 8, and return liquid and gas from the bottle flows through passage 7 to the tank. The valves 20 are spring urged closed and are moved axially via valve rods 21, 21c actuated by pivoted levers 31 engaging two further cam tracks on the drum cam. The latter is rocked by a lever 30 engaging a notched plate 29 fixed to the cam spindle, and the other end of the lever is connected to the elbow of a bell crank lever 33, Fig. 7, normally urged by a spring 37 to the position in which the liquid and return valves are opened and the counter-pressure valve closed. At the end of the filling period a roller 34 of the bell crank lever engages the surrounding cam track to turn the drum cam to momentarily lift and close the counter-pressure valve and allow the liquid and return valves to close. The filled bottle is then withdrawn, a fresh empty bottle applied over the filling tube, and the bell crank lever is moved by the cam track to effect a counter-pressure filling operation. Ball valves 10 and 26 close the liquid flow to the passage 6 and the gas and liquid return passage 7 respectively, if a bottle should break. Should a filling head not receive an empty bottle an electric switch is automatically operated by the appropriate bottle platform whereby a solenoid is energized to push a plunger 42, extending through the roller 34, inwardly to engage an abutment 36 and thereby to hold the bell crank lever in a position where the filler head valves remain closed.
