Abstract: 1418299 Lasers CARL ZEISS-STIFTUNG [trading as CARL ZEISS] 11 Dec 1972 [13 Dec 1971] 57125/72 Heading H1C In a stimulated Raman effect system in which a Raman medium such as H 2  is contained between dichroic resonator mirrors and is excited by an external laser, the frequency of the stokes and anti-stokes output radiation produced by scattering may be selectively varied over a range extending from the far infra-red to the near ultra-violet by the combination of a tunable dye excitation laser and a controlled variable pressure applied to the Raman medium. The dye laser, Fig. 1, comprises an active medium 2 of fluorescein, rhodamin 6G or bresyl Violet which is pumped by a flash lamp 1, the laser output being focused by a lens 5 into a Raman cell 10 formed with windows 4, 5. A resonator formed by coated dichroic mirrors 6, 7 is contained within the cell, mirror 6 transmitting the excitation beam from the laser and mirror 7 being partially transmissive of the Raman scattered radiation. In a modification Fig. 2, the resonator mirrors 6, 7 are located outside the Raman cell which is side excited through an additional window 11. A further arrangement, Fig. 3, uses a laser with a plurality of flash lamps 17, the output of the laser active medium 16 being tuned by a device 22 and applied to a Raman cell 20 through a cylindrical lens 19. A cylindrical mirror 18 lines the inner wall of the cell which is provided with resonator mirrors (not shown) along its optical axis 21.

Patent GB-1299896-A (GB)
Title: Extended aperture log-periodic and quasi log-periodic antenna
IPC: H01Q11/10
Filed: 1969-12-02
Abstract: 1299896 Aerials TECHNOLOGY FOR COMMUNICATIONS INTERNATIONAL 2 Dec 1969 [9 Dec 1968] 58862/69 Heading H4A A broadband aerial comprises a feed means extending along an axis and a plurality of different linear radiating elements, one end of each of which is directly coupled to the feed means. The spacings between adjacent elements increase in a preselected manner from one end to the other of the feed means. Capacitive means is associated with at least one element, for capacitively loading said element at at least one location intermediate its two ends. As described, a transposed transmission line 80, Fig. 6, feeds twelve parallel V-shaped dipoles 81 to 92. The lengths of the three lower frequency dipoles 81 to 83 decrease in log-periodic fashion, as indicated by the lines 98 from point 95 on the axis. The lengths of the intermediate frequency dipoles 84 to 89 exceed by progressively increasing amounts the lengths of simple logperiodic dipoles which would occupy their positions, and capacitance loadings are provided along them in compensation. There is a single capacitor in each element of the dipoles 84 to 86, and two, spaced apart in series, in each element of the dipoles 87 to 89. The lengths of the three higher frequency dipoles 90 to 92 again decrease in log-periodic fashion, as is indicated by the lines 99 from the point 95, and there are two capacitors in series along each dipole element. The aerial operates over a wide frequency band with a nearly constant aperture. The capacitors may be constituted as shown in Fig. 2. Here an element 35 comprises an inner portion 36, which is connected to a feeder 12a, an outer portion 38, and a central portion 37, which overlaps the other portions at 41, 42 to provide two capacitors in series. In other embodiments, all elements have lengths in log-periodic relationship, but capacitors are provided intermediate their ends. Dipoles may be used (Figs. 1, 3, not shown) or monopoles with intermediate phasing units along the feeder (Fig. 5, not shown). In an array of four aerials 121 to 124, Fig. 7, the respective feed lines may be spaced apart only about one quarter wavelength at the lowest frequency, so avoiding grating lobe formation when the radiated beam is steered by phasing the respective sources 161 to 164. The lengths of the outwardly extending elements of the end aerials 121, 122 are in log-periodic relationship. The lengths of all other elements are the same, and appropriate capacitive loadings are introduced using either one capacitor or two to four capacitors in series. Such arrays may also be arranged in annular or part-annular fashion (Figs. 9, 10, not shown). In another embodiment, two aerials 173, Fig. 8, are supported by a mast 175 and converge to a common vertex 180, to provide a radiation pattern which in elevation is substantially independent of frequency.

Title: Fibre treatment process and apparatus
IPC: H05B6/80
Filed: 1971-12-20
Abstract: 1378160 Curlers L'OREAL 20 Dec 1971 [21 Dec 1970] 59090/71 Heading A4V [Also in Divisions A5 and H5] The hair curler, roller, or hood of Specification 1376136 is modified by incorporating the high frequency current generator inside the conductive envelope of the resonator or by locating a high frequency power amplifier in the envelope. As shown the hair curler comprises a P.T.F.E. core carrying windings 14, 15 and a conductive envelope comprising a conducting disc 2 a perforated removable cylinder 5 and a metal base member 7. Mounted on the base 7, which is finned for cooling is a NPN transistor 9. A coaxial cable comprising a core conductor 10 and a conducting sheath 11 is connected to the base member 7 and to the emitter of the transistor 9 by a wire 12. The base of the transistor is connected to one end of coil 14, the other end 14a being free. One end 16 of coil 15 is connected to the collector of the transistor 9 and its other end to a lead 17 connected to core 10 of the coaxial cable by a coaxial filtering capacitor 18. The base of the transistor 9 is connected to the conductor 17 by a resistance 19. This arrangement ensures that the interval frequency of the resonator is always the same as that of the generator. In Fig.3 (not shown) a high frequency generator fed by a coaxial cable and located in a compartment of the resonator cavity feeds energy into the cavity by means of a coupling element. This embodiment may be modified by replacing the high frequency generator by a high frequency power amplifier which is fed with a D.C. amplifying current and a low power high frequency current along the coaxial cable. One low power high frequency source may supply a plurality of curlers of this construction. In Figs.4 and 5 (not shown) the high frequency generator located within the resonator cavity includes two transistors and associated circuitry.

Abstract: 1,245,607. Lasers. ELLIOTT BROS. (LONDON) Ltd. 17 March, 1970 [18 Dec., 1968], No. 60129/68. Heading H1C. In a gas laser in which the resonator mirrors are mounted on substrates, at least one of the substrates is apertured to provide a gas discharge path which extends from the laser active medium between the mirrors to an electrode located rearwardly of the apertured substrate. A helium-neon laser is shown in Fig. 1 in which the gas is contained within a cavity formed by mirror substrates 1, 2 and a glass ceramic tube 3, a concave and a plane resonator mirror being formed on the substrates by multilayer coatings 4. Laser emission takes place in a capillary tube 14 secured to the substrate 1 at an end which is formed with concentric gas passages 16, 17, 18. Passages 16 and 17 are coupled by a port 23 which forms a part of a gas discharge path deflected away from the mirrors, the path extending between a cathode 12 and an anode 9 through the capillary and through apertures 6, 7 in the substrate 1. A further substrate aperture 5 couples gas passage 18 with a pump stem 8. Radiation is emitted from the laser through substrate 2. In a modification, Fig. 2 (not shown) radiation is emitted through substrate 1. An alternative embodiment, Fig. 3, has the capillary 36 and two tubes 34, 35 carried by a central support member 33, the ends of the capillary being closed by Brewster windows 37, 38, and communicating passages 39, 40 being formed in its side walls through which the gas discharge extends. An anode 45 which passes through an aperture 41 in one substrate 31 is positioned adjacent one passage, and the gas discharge path between the anode and a cathode 47 passes through an aperture 42 in substrate 32. A spare cathode is provided. The laser may be supported by a resilient sleeve 55 in a sealed housing 56 which includes a tilted end window 57 for the laser emission 52. A gas or liquid introduced into the housing through a stop cock 60 may be used for frequency tuning over a limited range by using its pressure to impart small dimensional changes to the laser.
