Title: Maser or laser apparatus comprising spherical active material
Inventor: MORANTZ DANIEL JOSEPH
IPC: H01S3/042
Filed: 1962-04-16
Abstract: 1,042,312. Lasers. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 11, 1963 [April 16, 1962], No. 14658/62. Heading H3B. In a laser the active material comprises an organic glass and one or more conjugated organic molecular species and is substantially spherical in shape. As shown in Fig. 1, the laser active element 11 is immersed in liquid nitrogen 12 in a quartz dewar flask 13 and is pumped by light from a krypton flash tube 14 the wavelength of which is controlled by filter 18. Since the active material is spherically shaped the stimulated radiation that escapes does so tangentially and the active material appears with a bright rim of illumination. Due to the spherical shape of the active medium the " whispering gallery " modes of the stimulated emissions are stored within the medium so that the laser operates for longer periods than normal. The elements may be formed by mixing the organic glass and the one or more conjugated organic species and then decanting drops of the mixture into a refrigerating fluid such as liquid nitrogen, the mixture on solidifying forming spherical droplets due to surface tension. If the organic glass is dextrose the formation of the spherical elements may take place at room temperatures by allowing drops of fused dextrose containing the desired conjugated organic species to fall into water, propanediol or other viscous liquid. By varying the temperature of the fused dextrose the shape of the drop can be varied, e.g. a drop with a long tail can be obtained, Fig. 2 (not shown) and the light energy may be extracted as a narrow and intense beam. Other substances which form organic glasses at room temperature are amorphous plastics and neat benzophenone. In the embodiment of Fig. 3 (not shown) light may be extracted from the whispering gallery modes at a selected time after they have been initiated by using a light guide of substantially the same refractive index as the material of the laser element and moving the guide into contact with the element when required. The laser element may be in the form of a hollow shell, Fig. 4 (not shown), where a shell 27 of glass or quartz is lined with a thin layer 28 of laser material. At the centre of the shell is exciting light source 29 and energy is extracted from the system via a light guide. The lasing material may be positioned on the exterior of the shell. The organic glass may comprise a mixture of ether isopentane and alcohol, methylcyclohexane and isopentane, ether or dextrose. Suitable conjugated organic species are napththalene, anthracene, phenanthrene, pyrene, diphenyl triphenylene, acetophenone, benzaldehyde, benzoin, benzophenone, diphenylamine, eosin, fluorescein, α-napththol, #-naphthol, propiophenone or salicyclic aldehyde.

Liquid draining into an enclosure under vacuum conditions is transferred by an electrically driven pump into a discharge line, the pump being started and stopped and an electromagnetically operated valve in the discharge line opened and closed by a switch which operates automatically when the liquid rises and falls above and below predetermined limits respectively. In Fig.2, oil draining from a cable or joint during impregnation enters an inlet 6 of a vessel 1, formed by a cylindrical glass wall and metal end-plates, in which vacuum is maintained by an air suction line 19. Whenever the oil rises to a predetermined level, a float 17 causes magnetic operation of a switch 16 so that an eletric motor 12 is energized to drive a helical gear pump 7 and thereby discharge oil from vessel 1 through a line 8 in which a solenoid-operated valve 10 is opened simultaneously with the energization of motor 12. Switch 16 remains closed until the liquid falls to a lower predetermined level at which the pump is stopped and valve 10 closed to prevent loss of vacuum. Pump 7 may be mounted within vessel 1 and motor 12 outside, the coupling between them being surrounded by an oil seal.

Title: Improvements in or relating to means for steadily varying the pressure of air in a closed room such as an aircraft cabin
IPC: B64D13/04
Filed: 1947-06-05
Abstract: 651,330. Regulating cabin pressure. SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES DU SUD-OUEST. June 5,1947, No. 14927. Convention date, June 6, 1946. [Class 4] [Also in Group XXIX] Apparatus for producing a gradual variation of pressure in an aircraft cabin in which an excess pressure prevails with reference to the external atmosphere following a disturbance of the steady state conditions prevailing comprises a balanced valve, itself controlling, or acting as a pilot valve to a main valve controlling the exhaust of air from the cabin, the balanced valve being mechanically loaded and subject to the action of a member responsive to the differential of the pressures in the cabin and in a further chamber communicating with the cabin through a restricted passage. In an embodiment, the cabin P2 communicates with a control chamber 1 through a restriction 2, and the chamber 1 communicates through a restricted passage 4 with the inside of a bellows 3 situated in the cabin. The bellows is thus subject to the differential of the cabin and control chamber pressures, and it actuates a double-beat valve 5 which allows the excess pressure in the cabin to flow through a conduit 9 to atmosphere or to the main valve actuator. The balanced valve is loaded by a spring 6 and the loading can be adjusted by a lever 7 and ratchet 7a. During ascent of the aircraft, spring 6 is placed in compression and during descent, it is placed in tension. If the flow of air from the cabin is small, this air escapes to atmosphere past or through a leaky piston 12 in a cylinder 13. If the flow from the cabin is so great that it cannot leak away sufficiently quickly, a pressure will be built up under the piston 12 and the latter will rise and open a valve 11 allowing a larger flow from the cabin. Bellows 3 may be situated inside chamber 1. In a modification for maintaining a constant pressure in the cabin when a predetermined altitude is reached, the air flowing through conduit 9 must first open a bellows-type relief valve before it can flow to the cylinder 13, and in a further modification, the relief valve is connected to the cylinder in parallel with the control valve 5 so that a varying controlled pressure or a constant pressure can be maintained in the cabin at will. Specification 646,287 is referred to.
