Title: Improvements in or relating to synthesis of 4-hydroxycoumarins
Inventor: STAHMANN MARK ARNOLD
IPC: C07D311/46
Filed: 1942-11-23
Abstract: 4-Hydroxycoumarins are prepared by the method described by Pauly and Sockemann which consists in reacting an acetyl salicylic acid ester of the formula <FORM:0578589/IV/1> where R is either hydrogen or a monovalent hydrocarbon group and p  R1 is a monovalent hydrocarbon group with an alkali metal or an alkali metal alcoholate or amide modified in that the reaction is carried out in an inert solvent instead of using molten starting materials as was done by Pauly & Sockemann.  As solvents there may be used high boiling hydrocarbons and petroleum fractions, or high boiling ethers such as the dimethyl ether of tetraethyleneglycol.  The reaction temperature should be between 160 DEG -280 DEG  C.  In examples there is described the formation of 4-hydroxy coumarin, 3-methyl-4-hydroxy coumarin, 3-ethyl-4-hydroxy coumarin, 3-n-propyl-4-hydroxy-coumarin, 3-isopropyl-4-hydroxy coumarin, 3 - n - butyl - 4 - hydroxy coumarin, 3 - n - amyl - 4 - hydroxy coumarin, 3 - hexadecyl - 4 - hydroxy coumarin, 3 - phenyl - 4 - hydroxy coumarin, 3 - benzyl - 4 - hydroxy coumarin.  In each case the reactants are mixed and boiled under reflux, the catalysts being in each case metallic sodium, with the alternatives of potassium and lithium being mentioned.

Abstract: 830,726. Electrical measuring systems. HARTMANN & BRAUN A.G. May 23, 1958 [April 15, 1958], No. 16595/58. Class 40 (1). [Also in Group XXXVI] Apparatus for determining the viscosity of a liquid comprises three units operatively connected together by readily releasable means and mounted on a support, one unit comprising a measuring chamber containing a torque transmitting and a torque receiving member immersed in the tested medium, the second unit containing means for driving the torque transmitting member at a constant speed and the third unit containing an electrical system for measuring the torque transmitted through the medium to the receiving member by generation of an opposing torque. As shown, a vertical mounting-board 1 carries supports 2, 3 between which is inserted the first unit 4 consisting of a chamber 5 having inlet and outlet pipes 6, 7 for the tested liquid (particularly lubricating oil) and containing torque transmitting cylinder 12 driven by a magnetic coupling 13, 19 from a synchronous motor 23 contained in the second unit 22. Coaxial with the cylinder 12 is a torque receiving cylinder 14 coupled to a moving coil 35, contained in the third unit 34, via a magnetic coupling 15, 21. The moving coil 35 is pivoted between the poles of a magnet 36 and has an arm 38 carrying a vane 39 which may be interposed between a light source 40 and a photo-electric cell 42. The photo-electric cell output is amplified by a valve or transistor amplifier 43, the output of which is fed back to the coil 35 to oppose the torque of the cylinder 14. Thus the deflection ofthe coil 35 and the coil current are dependent on the viscosity of the liquid in the chamber 5. The coil current is . modified by the output of a resistance thermometer contained in chamber 5 and amplified by magnetic amplifiers 49 before being fed to an indicator 57 and/or a recorder 58. The temperature of the chamber 5 is maintained constant by a thermostatically-controlled waterjacket 8, lagged at 11. The synchronous motor 23 is fed with constant frequency current from a quartz oscillator 31 and a valve or transistor amplifier 32. The motor 23 may be started by an asynchronous motor 24 or a self-starting type may be used. Plug-in power supply units 26, 44 and lamps 53, indicating the failure of any one unit, are provided. The construction of the assembly is further described in Group XXXVI.

[Class 39(iii)] [Also in Group XXXVII] A thermostatically-controlled electrically-heated iron in which the thermostat may be set to operate at a predetermined temperature, is provided with a warning lamp 10 adapted to be energised when the temperature of the sole plate 1 of the iron exceeds that at which the thermostat is set. A bimetal strip 9 is disposed in a recess 8 in the sole plate 1, the free end of the bimetal being secured by a rod 27 to the centre one 14 of three metallic blades 13, 14, and 15, all fixed at one end in a terminal block, and at their free ends carrying contacts 31, 30, and 32 respectively. The blades 13 and 15 are joined together at their free ends by an insulating plate 33 having a rearwardly extending lug 34 cooperating with a cam 37 on a shaft 38 having a knob 39, whereby the operating temperature of the thermostat may be pre-determined. Contacts 31 and 30 are normally closed, the heating element 2 being then energised, and a signal lamp (not shown) being short-circuited. As the bimetal strip 9 curls, blade 14 is allowed to rise, and so open the heating circut, the signal lamp then glowing, it being shunted across the supply terminals. Should then the thermostat be set to operate at a lower temperature while the iron is still hot, the blades 13 and 15 will be depressed, and contacts 30 and 32 will close to cause warning lamp 40 to glow. The two lamps are preferably neon tubes each in series with a small condenser.

Filed: 1974-04-17
Abstract: 1461815 Treating textile yarns RHONEPOULENC-TEXTILE 17 April 1974 [18 April 1973] 16831/74 Heading D1L Fluid treating agents are applied to textile yarn in apparatus comprising as shown in Fig. 1 a supply tank 2 containing treatment fluid which passes through an ejector 3. The fluid exits through the ejector outlet orifice 14 then passes into a stop valve chamber 5 acting as a modulator, whence it exits again to return to the tank 2 via the conduit 6. When injection is effected on the yarn a programming means 7 causes a membrane 9 in chamber 5 to be flattened against an inlet orifice 8 of the chamber 5, thus preventing the return of the fluid 1 to the tank 2 thus interrupting the circulation system. The fluid 1 then passes out through the suction orifice 13 of the ejector 3 and then passes to an injector 4 and treats a yarn 10 which travels preferably in bunched form in the confined space 11 of a pipe 15. It is preferred to use an injector 4 with one or more injection passages each receiving the pulsed fluid arriving from a separate ejector, each ejector being in a circulation system of a different treatment fluid. As shown in Fig. 3 the injection of four fluids c, d, e, f is provided for, the fluids being for example solutions of dyes of the three primary colours, the fourth being a dye adjuvant and so permitting dyeing to any desired shade by selecting the injected dyes.
