Abstract: 1,053,288. Masers; cavity resonators. VARIAN ASSOCIATES. Sept. 24, 1963 [Sept. 24, 1962], No. 37613/63. Headings H1C and H1W. In a hydrogen maser the transition of hydrogen atoms from one hyperfine state to another takes place in a composite particle storage cell and cavity resonator 4 comprising a body 10 of solid dielectric material having a conducting coating thereon arranged to establish the conducting boundaries of a cavity resonator and a cavity 12 formed in the body 10 for confining the hydrogen atoms. Hydrogen atoms in the upper F= 1 hyperfine state are selectively focused by magnets 3 from a hydrogen beam produced by discharge tube 1 into the storage cell and cavity resonator 4. The cavity resonator is tuned to the transition frequency between the upper F = 1 hyperfine state and the lower F = 0 hyperfine state of the hydrogen atoms so that transition of the atoms between these states results in maser oscillations which are coupled out via coaxial line 6. The body 10 comprises a sphere of quartz coated with silver and provided with a cavity 12 lined with polytetrafluoroethylene which permits repeated collisions of hydrogen atoms with the walls without disturbing the interaction with the radiation field in the cavity. To increase the beam flux in the storage cavity 12 an opening contains a collimator 13 consisting of a bundle of small, thin tubes which prohibits the randomly directed atoms within the cavity from leaving. Scratches or discontinuities 14 coaxial about an axis parallel to the beam axis are provided on the conducting resonator coating to guide the r.f. currents therealong. Orthogonal coils 15, 16 provide a small static magnetic field of variable orientation with reference to the r.f. magnetic field in the cavity for selection of the desired hyperfine transitions. The entire structure is enclosed by metal shields 17 and heat insulating material 19. In the embodiment of Fig. 3 (not shown) the dielectric body is in the shape of a cylinder about the beam axis.

Abstract: 1,095,415. Surveying instruments. BERGWERKSVERBAND G.m.b.H. Aug. 20, 1965 [Aug.20, 1964], No.35744/65. Heading G1F. An apparatus for making angular surveying measurements in conditions of darkness or poor visibility such as in underground working comprises a laser beam emitter 1, mounting means for adjustably orientating such emitter in vertical and horizontal planes, and indicator means 7 providing angular azimuth and elevation readings of the direction in which the beam extends relative to a fixed line 17 determined by a theodolite telescope 53. A double laser beam emitter may be suspended from the roof of a working, one beam 3 being directed to a known fixed point 32 and the other 4 to the working face 34. When the laser is used in conjunction with a theodolite 10 (Fig.4), the optical axis may be kept parallel with the laser beam 2. The boundaries of an underground working are found by taking measurements in vertical and horizontal planes perpendicular to the laser beam. For measurement of distance the laser beam is tilted on the theodolite mounting until the laser beam coincides with the optical axis at the target point, Fig. 5 (not shown). In a further embodiment (Fig. 8), a theodolite telescope 53 with its optical axis 17 directed at a target point and a second geodetic instrument 5 with a laser beam 2 directed parallel with its optical axis are mounted on a common support 8. The instrument 5 and laser beam are adjusted so that the laser beam coincides with the axis 17 at the target point. The angle of the laser beam with the base is then found using a scale 7 from which the distance away of the target point can be found, knowing the distance between the two geodetic instruments. In a modification the angle of the laser beam may be kept constant and the distance between the two instruments varied.

Abstract: 1,225,912. Measuring flow-rate electrically. H. KAJIURA, K. WATANABE, H. TOMIYASU and T. INAGAKI. May 28, 1969, No.26856/69. Heading G1N. The rate of flow of a powder or granular material is measured by allowing it to fall on to an inclined deflecting plate 2 (Fig.2B) mounted on a fulcrumed beam 9, thereby producing a component of force in the horizontal plane against a spring 5, the resultant displacement, measured by a differential transformer 6, being indicative of the flow-rate. In another embodiment (Fig. 3) the impact force on the deflecting plate b has a component along the beam c.
