Title: Atomic resonance apparatus
IPC: H01S1/06
Filed: 1965-10-10
Abstract: 1,130,563. Atomic resonance. VARIAN ASSOCIATES. 1 Oct., 1965 [5 Oct., 1964 (2)], No.41820/65. Heading G6P. [Also in Division H1] Gas atomic resonance apparatus comprises a buffer gas including a quenching gas constituent at a partial pressure of between 5 and 20 torr at room temperature such that enhancement of the atomic resonance is obtained. A rubidium maser, Fig. 1, includes a cavity 1 filled with Rb<SP>87</SP> vapour and a buffer gas of nitrogen and is pumped by radiation from a Rb<SP>87</SP> lamp 4 filtered by means of a Rb<SP>85</SP> filter 5. The pumping depopulates the F = 1 sub-level of the ground state of the Rb<SP>87</SP> atoms by excitation to higher energy states from which the atoms decay to the F = 1 and F = 2 levels of the ground states resulting in an overpopulation of the F = 2 level. The splitting of the levels into Zeeman sublevels is achieved by means of coil pairs 13 adjusted to provide a uniform polarizing field H o . In operation the cavity resonator is tuned to the ground state (F=2, M=0 F=1, M = 0) hyperfine transition so that random microwave transitions from the F=2 to the F = levels excite the cavity resonator in such a way that the fields of the cavity interact back on the gaseous atoms to produce coherent oscillations. Output is coupled out from waveguide 8. The temperature of the medium is maintained at an optimum for the transitions by means of oven 7 and stray magnetic fields are suppressed by shields 8. Helium, argon or hydrogen may be employed instead of nitrogen and any alkali vapour may be employed as the active medium. Fig. 6 (not shown), describes a further apparatus in which an evacuated glass envelope is disposed between the gas medium and pumping light entrance to prevent undesired absorption of the pumping light. In order to compensate for changes of the resonance frequency of the atoms due to changes in the intensity of the pumping light, i.e. light shifts the apparatus of Fig. 11 is employed. A first Rb<SP>87</SP> lamp 42 has its parameters adjusted to produce a negative light shift and a second lamp 45 is provided to shine on to a half-silvered mirror 46 and then into cavity 1, the second lamp having its parameters adjusted to produce a positive light shift. In operation the ratio of intensities of the pumping radiations applied to the cavity is adjusted by means of variable transmission filters 43, 47 until a point is reached at which zero light shift is observed when filter 49 is varied. In order to compensate for aging of the lamps 42 and 45 modulator 52 supplies a 400 c.p.s. signal to the Kerr cell filter 42 to amplitude-modulate the superimposed pumping light beams. The frequency modulated output signal of the cavity is detected by 53 and converted to an amplitudemodulated signal before being compared with the original modulation signal in phase detector 54. The D.C. error signal is fed back to filter 47 for controlling the ratio of intensities of the pumping beams. The apparatus may be used as a frequency standard.

Title: Process for the manufacture of spontaneously crimping polyolefine filaments
IPC: D01D5/30
Filed: 1962-11-09
Abstract: 979,083. Crimpable polyolefin filaments. SOC. DE LA VISCOSE SUISSE. Nov. 9, 1962 [Nov. 24, 1961], No. 42392/62. Heading B5B. [Also in Division D1] Spontaneously crimping polyolefin filaments are made by stretching to at least 1.5 times their original length composite filaments composed of two different mutually adherent fibre-forming polyolefin constituents side-by-side along the length of the filaments the two constituents differing in specific viscosity (determined in 0.1% solution in tetrahydronaphthalene at 135‹ C.) by at least 0.1. Specified polyolefins include high-pressure polyethylene, low-pressure polyethylene, and polypropylene. Any process effecting the necessary viscosity difference may be used-e.g. two polyolefines of equal viscosity may be fed into separate melting devices and melted under different conditions. Preferably, the two constituents are simultaneously meltspun using the spinnerets shown. Fig. 1 shows a spinneret for making yarns consisting exclusively of composite filaments, two melts P 1  and P 2  being supplied to the melt-chambers 2 and 3. The resulting filaments are of the " side-by-side " form. Figs. 5 and 6 show a spinneret for making yarns containing both unitary and composite filaments. Two melts P 1  and P 2  are supplied to two differently-shaped melt-chambers 15 and 16. The orifices 17 in the bottom of chamber 15 are equidistant from the partition 21 and spinneret orifices 23, while the orifices 18 in the bottom of the chamber 16 are disposed at different distances from the partition 21 and the spinneret orifices 23. The number of orifices 17 differs from the number of orifices 18. Owing to the different shapes of chambers 15 and 16, of the different distances of the individual orifices 17 and 18 from the partition 21 and the spinneret orifices 23, and of the different numbers of orifices 17 and 18, different pressure conditions are set up immediately in front of the spinneret orifices 23a-23h. Some orifices, e.g. 23a and 23b, are charged exclusively with melt P 1 , and the remainder, e.g. 23c to 23h, with different proportions of the two melts P 1  and P 2 , so that unitary filaments emerge from 23a and 23b, and composite filaments from the remainder, these composite filaments differing from each other in the proportions of the two melts they contain. Either or both components may contain matting agents, pigments, stabilizers or plasticizers. The ratio of unitary to composite filaments can be varied by adjustment of the above variables. Conventional stretching means are used, and the stretched filaments may be allowed to crimp by release of tension, the crimped filaments then being heat-set in the slack state. Alternatively, the spontaneously crimping filaments may be made into yarns with unitary filaments and the yarns then stabilized either by twisting or by heat-setting under tension.

Abstract: 1453888 Automatic temperature control DCA FOOD INDUSTRIES Inc 1 Oct 1974 [1 Feb 1974] 42492/74 Heading G3R [Also in Division H5] The power input to heaters located within a micro-wave cavity is controlled by means including a temperature sensor in an air-sampling zone outside the cavity. Air can pass freely from the cavity to the zone, but micro-waves cannot. The embodiment is a combined micro-wave/ infrared oven (see Division H5) whose infrared heaters 38, 40 are controlled by the temperature of the sensor 60 which actuates a thermostat switch 74 and a relay 76 to supply power whenever the temperature falls. A timer 82 may be connected as shown. This defines alternate ON and OFF periods of a switch 82a and the heaters are powered whenever both 74a and 82a are closed. In this form the time periods are pre-set at 82c. Alternatively, the time-control contacts 82a alone may complete the power supply circuit, but the ratio of ON to OFF periods be adjusted automatically by the temperature sensor output.
