Abstract: 1,130,400. Lasers. TURLABOR A.G. 6 Sept., 1967 [7 Sept., 1966], No. 40785/67. Heading H1C. In a laser, the active medium is surrounded by a solution containing an organic phosphor for converting part of the pumping radiation to a wavelength suitable for absorption by the active medium. Ruby crystal 3 has silvered ends 5, one lying at one focus F1 and one at the surface P1 of a reflecting ellipsoidal cavity 2. A xenon flashtube 4 lies between corresponding points F2, P2 at the other end of the ellipsoid. The crystal and the flashtube are enclosed within transparent conduits 11, 13 through which the organic phosphor solution is pumped, acting both as a radiation converter and as a coolant. Preferably the organic phosphor is 2 - (4<SP>1 </SP>- biphenylyl) - 6 - phenylbenzoxazole and the solvent is dekahydronaphthalene. Several different phosphors may be dissolved in one or several solvents, to concentrate more of the pumping energy into the absorption bands of the laser crystal. The phosphors may form a " chain " in which the absorption region of one phosphor coincides with the emission region of another. Neodymium glass may be used as the laser active medium instead of ruby, and a continuously-operating mercury lamp may replace the flashtube.

IPC: G01D5/243
Filed: 1959-12-02
Abstract: 973, 996. Frequency measurement; electric measuring instruments. JOSEPH LUCAS (INDUSTRIES) Ltd. Dec. 2, 1960 [Dec. 2, 1959], No. 40919/59. Headings G1Q and G1U. [Also in Division H2] An arrangement for imparting an angular movement to a rotor 9 comprises a transistor 10, a means for applying intermittent pulses of one polarity to the base of the transitor, a first winding 5 connected between the collector of the transistor and a D.C. source 11 of the same polarity as the pulses, a second winding 6 connected between the transistor base and a D.C. source of opposite polarity, which is also connected to the emitter, a common core 4 on which the first and second windings are wound, a third winding 8 and a diode 13 connected in series across the first winding, a second core 7 on which the third winding is wound, the second core being spaced from the common core, and an angularly moveable induction disc 9 so arranged in relation to the cores that angular movement will be imparted thereto by the interaction of the flux produced by the second and third windings after the transistor has been cut off. The system may be used in one application for measuring the angular velocity of a rotating part, i.e. as a speedometer or tachometer, the part being used for example to operate a cam operated contact breaker 14 to supply pulses to the transistor base. The pulse on the base causes the transistor to conduct, and the current increases cumulatively by regenerative action between the windings 5 and 6 until the winding 5 is saturated, after which, because no voltage is induced in the winding 6, the transistor cuts off, causing a current to flow through the diode 13 and the winding 8. Thus the flux in the winding 8 increases as that in the winding 5 falls. These changes exert a torque on the disc 9, moving it against a spring. The average torque will depend on the pulse frequency, so that by suitable calibration the instrument can be used as a tachometer or speedometer. Alternatively, by applying the pulses through a rectifier from a source of alternating current the instrument can be used as a frequency meter. If the spring is omitted the instrument may be used as a low torque D.C. motor rotatable at an angular velocity proportional to the frequency of the pulses applied to the base of the transistor. Either a PNP or NPN transistor may be used, with appropriate supplies.

IPC: C07C17/00
Filed: 1960-12-02
Abstract: 2,6-Dichlorobenzal chloride and/or 2,6-dichlorobenzyl chloride are made by reacting 2,6-dinitrotoluene or 2-chloro-6-nitrotoluene with chlorine or thionyl chloride at a temperature of at least 130 DEG C., preferably between 160 DEG  and 195 DEG C. 1,2,3-trichloro benzene, 2-chloro-6-nitrotoluene and 2-chloro-6-nitrobenzyl chloride may be formed as by-products. A halogenation catalyst, such as sulphur or phosphorus trichloride, may be used and/or the reaction vessel may be irradiated with ultra-violet light.  Although atmospheric pressure is usual, sub- or super-atmospheric pressure may be applied, if desired. An inert solvent, e.g. a chlorinated hydrocarbon may be present, and an inert gas such as nitrogen may be used instead of, or in addition to, an excess of chlorinating agent. 2,6-Dichlorobenzal chloride may be converted in a single step to 2,6-dichlorobenzaldoxime by reacting with hydroxylamine in an acid medium, preferably a concentrated mineral acid such as sulphuric acid, at a temperature between 30 DEG and 70 DEG C. Alternatively, 2,6-dichlorobenzal chloride may be hydrolyzed with an acid, such as sulphuric acid, or with acetic acid and zinc chloride, to 2,6-dichlorobenzaldehyde which is then converted to oxime by reaction with hydroxylamine in acid medium. Detailed examples are given.  The Provisional Specification refers more generally to the halogenation of nitro- or nitro-halo-alkylbenzene with chlorine or bromine or with thionyl chloride or thionyl bromide at a temperature of at least 130 DEG C. The starting materials may also contain at least one alkoxy group or COOR group, where R is alkyl, or a group R1, OR1 or COOR1, where R1 represents phenyl which is unsubstituted or substituted only by chlorine or bromine.

Abstract: 1,025,727. Automatic control of ice thickness. RANCO Inc. Oct. 13, 1964 [Oct. 31,1963], No No. 41786/64. Heading G3R The thickness of ice in the vicinity of electrodes is maintained between limits by supplying the electrodes from an unsmoothed rectifier and using amplified current variations to control a relay which switches a refrigerator on and off. Fig. 3 shows part of refrigerator evaporator coil tubing 13a which is immersed in a tank of water used for cooling milk. Stainless steel electrodes P 1 P 2  mounted on an insulating bracket 22 are arranged perpendicular to the tubing so that as ice 20 builds up round the tubing the area of the electrodes exposed to free water decreases and hence the resistance between the electrodes increases. In Fig. 2 this causes the A.C. component of unsmoothed current from a full-wave rectifier 38 to decrease through a resistor 41 and, when it is below a predetermined value, transistors Q 1 Q 2  are triggered to de-energize the heater 43 of a bimetallic relay 61 and stop the refrigerator compressor motor 15. The thickness of ice then decreases to a value at which the transistors re-energize heater 43 sufficiently to re-dose relay 61. The differential of relay 61 is such as to cause the ice thickness to be maintained between limits sufficiently separated as to avoid too frequent operation of the control system.
