Title: Improvements in and relating to Laser Apparatus
IPC: H01S3/106
Filed: 1966-07-28
Abstract: 1,156,525. Photo-electric systems. PHILCO-FORD CORP. July 28, 1966 [July 29, 1965], No.33886/66. Heading G1A. [Also in in Division H1 ] In a gas laser light transmissive means exhibiting a signal controllable anisotropy are included in the laster optical resonator. In the embodiment of Fig. 1 (not shown) an elongated tube containing a helium-neon mixture is inserted in an optical cavity defined by two spherical reflectors, the end mirrors of the tube being arranged normal to the cavity axis. A Kerr cell or Pockels cell which introduces a known anisotropy in response to an electrical signal from an amplifier is inserted in the cavity between one of the reflectors and the end of the tube. One of the reflectors is made transmissive so that some of the light energy passes therethrough to a Nicols prism and thence to a photo-diode. The Kerr or Pockels cell may be replaced by a sample of material of unknown optical characteristics which may be stressed electrically, mechanically or magnetically by signals applied thereto. The arrangement of (Fig. 1) may be arranged to operate as a frequency modulation system Fig. 2 (not shown) in which a Kerr cell is employed in the optical cavity. When a signal is applied to the Kerr cell only light plane polarized either perpendicular to or parallel to the magnetic field direction establishes a stationery mode and these beams will have a difference in frequency due to the difference in velocities and hence path lengths of the two beams. Changes in the potential applied to the Kerr cell will have different effects on the velocities of the beams so that modulation of the difference in frequency between the two beams is obtained by modulation of the Kerr cell voltage. The two beams are optically heterodyned by a photo-diode to yield a component at the modulation frequency applied to the Kerr cell from a microphone. The average difference frequency may be stabilized by sampling the two transmitted beams, detecting the difference frequency and using the detected difference to control the voltage applied to the Kerr cell. In the arrangement of Fig. 3 (not shown) the Kerr cell is replaced by a sample under test so that the frequency splitting and cross polarization amplitude can be measured at different values of fields applied thereto. The output from the optical cavity is in this case passed to a polarization analyzer and thence to a photo-detector and frequency analyzer. The polarization analyzer may be made rotatable and a scale provided so that the actual plane of polarization may be determined. In Fig.4 (not shown) a magnetic field is applied to the sample instead of the electric field of (Fig. 3) and in Fig. 5 (not shown) the sample is subjected to mechanical stress. In the arrangement of Fig. 6 three reflectors 80, 82, 84 are provided to define the optical cavity.

Abstract: 1,102,344. Transformers. BRENTFORD ELECTRIC Ltd., and C. B. HENMAN. 24 Aug., 1964 [29 Aug., 1963], No. 34284/63. Heading HIT. [Also in Division H2] The flux leakage and copper losses of an autotransformer, whose winding is tapped by slidiing brushes or rollers, are reduced by providing one or more compensating windings each of which is wound adjacent to but insulated from one part of the main winding and is connected in parallel with another part of the winding having the same number of turns as the compensating winding. Fig. 1 is typical of the two basic arrangements described and has a compensating winding 18 wound on the same former as the main winding 11 and underneath the part 21 thereof, the remaining part 20 being in parallel with the winding 18. In Fig. 4 the roller 17 only moves over a portion 40 of the main winding 11, the remaining portion 41 being wound underneath that part of the winding portion 40 which is connected in parallel with the compensating winding 18. In this arrangement the windings 18, 41 and the two halves of winding 40 have the same number of turns. The winding shown in Fig. 6 is divided into four equal sections 43, 44, 45, 46 and has two compensating windings 18a, 18b, respectively wound underneath sections 45, 44 and parallel connected to sections 43, 46. This arrangement may be modified by using two rollers maintained equi-distant from the mid-point of the winding, Figs. 8, 9 and 12 (not shown). In Fig. 10 the winding 11 is divided into seven sections 61 ... 67 of which 61 ... 63, 65 ... 67 have the same number of turns which is half as many as the section 64. Four compensating windings 18a, 18b, 18c, 18d are provided respectively wound underneath sections 65, 63, 66, 62 and parallelconnected to sections 61, 67, 64, the windings 18c, 18d forming a series circuit across the section 64. The compensating winding may comprise a number of tubular turns of copper or aluminium sheet wrapped around the core, each turn extending continuously along the length of the compensating winding. The arrangements disclosed are stated to improve the linearity of the variation of electrical output with the position of the roller 17 along the winding.

Abstract: 302,061. Wells, A. W. J. Dec. 22, 1027. Safety devices requiring both hands of operator to be occupied in starting and stopping machinery. - In power presses started by simultaneous actuation of two spaced handles, release of either before the ram has descended a safe distance trips the clutch and positively locks the driven shaft. Each of two actuating- handles M is coupled by arms M<1>, N<1>, a rock-shaft N, and an arm N<2> to one of a pair of spring-pressed bolts G, normally lying in the path of an arm F, which is pulled by a spring E<2> and is pivoted on a collar E fast on the press shaft A. The half-round clutch-key F<3>, adapted on depression of both bolts to coact with a notched driving-pulley (not shown), is operated by a complementary part F<2> of the pivot of arm F, on which is pivoted at H<1> a trigger H, pressed by a spring H<2>. Should either bolt G be prematurely released, it contacts with the tail H<4> of the trigger and projects the end H<3>, which is caught by a detent K, so rocking the arm F and key F<3>, the shaft A being arrested by an adjustable constantly-acting brake L and also positively locked. On withdrawing, by one hand, a spring-pin from a hole K<3> in the frame, the detent may be swung by the other hand about its pivot K<1> against spring- action, as shown by broken lines, so releasing the trigger H and allowing the press to finish its stroke. A lug K<4> on the detent obstructs a pin N<3> to prevent actuation of one bolt G while the safety device is inoperative.
