Title: Electric apparatus for boiling liquids
IPC: A47J27/21
Filed: 1972-05-03
Abstract: 1356502 Kettles &c. BELLING & CO Ltd 3 May 1972 [4 May 1971] 20683/72 Heading A4A [Also in Division G3] A liquid boiler heated by an electric heating element 2 has an electronic temperature sensor 8 exposed to liquid vapour when the liquid boils, the sensor being connected electrically to a current controlled switch device 4, 5 to interrupt the supply to the element 2 when the liquid boils. The term electronic temperature sensor is intended to include any device which has a temperature responsive electric-variable whose temperature coefficient is higher than the resistance/temperature coefficient of metals. In the embodiments described the sensor 8 is a thermistor with a positive or negative resistance/ temperature coefficient. As shown, the heating element 2 is supplied from A.C. supply 14 by relay contacts 4. A full wave-rectifier 16 supplies energizing current to relay coil 5 by way cf a smoothing capacitor 17. A normally non-conducting transistor 18 shunts the coil 5. A steam sensitive thermistor 8 is connected in the base emitter path of the transistor 18. When the temperature of thermistor 8 rises sufficiently it permits the transistor 18 to conduit. The relay coil 5 is thereby de-energized to open contacts 4. A second "bail dry" thermistor 8a which is thermally connected to the heating element 2 to sense its temperature is connected in parallel to the thermistor 8. In an alternative embodiment a normally conducting transistor is connected in series with the relay coil 5, and the thermistor is connected to its base to render it non-conducting when the liquid bails. In one embodiment the relay coil is shunted by a thyristor whose trigger electrode is connected to the thermistor 8. The relay may be replaced by a thyristor, a thyristor pair or a triac triggered directly by the thermistor or via a transistor. The thermistor 8 may be mounted in a steam duct in the housing of an electric kettle, in a washing machine, coffee percolator, or fat frier. The thermistor 8 may act to permanently de-energize the heating element on boiling, or it may cause the element to be switched on and off to keep the liquid temperature constant. The thermistor may be replaced by a semiconductor diode or a transistor.

Title: Improvements in or relating to the winding of bobbin-spun artificial threads
IPC: B65H54/74
Filed: 1943-12-10
Abstract: 581,911. Winding thread. VANDERHOOVEN, C. C. Dec. 10, 1943, No. 20735. Convention date, Oct. 7, 1942. [Class 120 (ii)] Bobbin - spun artificial thread is wound into a package on a rotating bobbin which is gradually decelerated to give substantially constant surface speed to control the thread tension, by a method in which the deceleration is independent of the package size and in timed relation with the bobbin rotation being effected, e.g.; by a cam to operate the variable speed gear or by a variable speed gear, so that the change in r.p.m. does not depart substan-. tially from the change in r.p.m. typified between the curves 2a and 5a of Fig. 2 Adjustable cone drives 39, 40 are driven from a constant speed motor 46, the adjustment being effected by levers 49, 50 pivoted at 51, 52 moved by a specially designed double-cam 53 rotated from the shaft 42 of the cones 40 through a reduction gearing 61. The driven cones 39 drive the shaft 10 which drives the bobbin 14 and also, through a cam 24 and levers the traverse bar 33 and thread guide 34. The filament to be wound is led around a driven godet 37 to a loose roller 38, stretch being applied thereto before being wound at substantially constant speed. In winding bobbins of cylindrical form with frustoconical ends, the fall-off of bobbin revolutions is not uniform, see curve 2a, Fig. 2, but a wind-on speed which is substantially uniform, see line 2b, Fig. 3, is obtained. In winding right cylindrical bobbins, it is stated that better winds are produced when the bobbin fall-off speed is as shown in curve 3a, Fig. 2, which is equivalent to a speed curve 3b, Fig. 3 which rises slightly at first (to produce a slight increase in tension) and then falls slowly along a substantially straight line. If, however, in a right cylindrical wind it is required to have a constant speed of wind, line 2b, Fig. 3, the cams 53 are shaped to give a fall-off speed according to the line 5a, Fig. 2.

IPC: G01N7/14
Filed: 1960-06-14
Abstract: 956,711. Measuring gas in liquids. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 31, 1961 [June 14, 1960], No. 20928/60. Heading B1X. [Also in Division B8] Apparatus for measuring the gas content of a liquid comprises a chamber consisting of a lower liquid-collecting portion, a compressible sealing element around a rim at the top of said portion, a lid adapted to rest on said sealing .elements to seal the interior from the atmosphere, said lid being held in place only by gravity and (when the internal pressure is sub-atmospheric) by atmospheric pressure, an outlet from the chamber for evacuation of air, an inlet for admitting liquid into the chamber from a sample bottle and means for connecting the chamber to a vacuum gauge. As shown in Fig. 3, the liquid-collecting portion is in the form of a shallow dish, the floor 24 of which may be levelled by feet 23. The lid 28 is placed on the rim 25 to compress sealing ring 26. The lid supports a tube 29 having a valve 32 connected to a vacuum pump, which may be opened to evacuate the chamber to 0À02 mm. Hg. ; the lid may "dish" and a slight chamfer 27 prevents rupture of the seal. When gauge 34, also supported by the lid, indicates the required vacuum, valve 32 is closed and a valve 14 connected to sample bottle 5 is opened causing liquid to flow as a thin layer over floor 24. Dissolved gases leave the liquid and the steady pressure attained is read on gauge 34. Moisture is removed by drying agent 38, e.g. phosphorus pentoxide, supported in thimble 36 by cotton wool pad 37. In a modification, Fig. 4 (not shown), the liquid collecting portion is in the form of an inverted conical base having a short vertical cylindrical section near its apex in which there is an aperture fitted with a reciprocatory operating rod for an agitator. The rod is attached to a diaphragm sealing the apparatus. The lid 28 may be glass or transparent synthetic resin plastic.

Title: A method and apparatus for the spectrometric or spectrographic analysis of representative samples taken from finished metal products
IPC: G01N21/67
Filed: 1964-05-21
Abstract: 1,034,162. Discharge apparatus; arc lamps. HUTTENWERK OBERHAUSEN A.G. May 21, 1964 [July 20, 1963], No. 20928/64. Headings H1D and H1X. [Also in Division G2] Representative samples taken from finished metal products are first melted and then, while still molten or after solidification, are examined spectrometrically or spectrographically in the same equipment. A system, Fig. 1 (not shown), comprises a water-cooled container 1 acting as a melting crucible and holding a sample 2 which is preferably connected as an anode. The cathode and counter-electrode 3 consists of a material, e.g. graphite, silver, aluminium or copper, containing none of the elements to be analysed for. When analysing incompletely killed steels, an aluminium counter-electrode, which has a deoxidizing action, is preferred. The electrode 3 is connected to a D.C. source 4, a source 5 for igniting the D.C. arc, and a spark oscillator 6, energized in succession by a controller 7. Phase displaced rotary interruptors 12 and 14 are driven by a synchronous motor 13. An optical stop, e.g. a rotating sector, or alternatively an electrical stop, is provided in the spectrometer and synchronized with the motor 13. In operation, the D.C. melting arc is interrupted for short periods during which A.C. pulses from the oscillator 6, or alternatively pulses from a D.C. source, are applied to provide the light source for the analysis. Alternatively the pulses may be superimposed on the D.C. melting supply, or in exceptional cases the D.C. melting arc may be used as the light source. The melting may take place in an inert atmosphere, e.g. argon. A jet of gas such as helium or, if analysis for carbon is not required, hydrogen may be used for rapid cooling when analysing after solidification. An apparatus, Fig. 3 (not shown), for melting samples which are analysed after solidification comprises two vacuum-tight chambers 21 each containing a melting crucible 1 and two counterelectrodes 3 supported by a water-cooled holder 22 passing through a threaded guide 23 and provided with a nut 24 for height adjustment. Each chamber has an optical window 26 and a tube 27 for pumping out and admitting working gas. The metal base 25 is water-cooled, and the entire apparatus can be adjusted for height by a ring 30 and can be rotated through 180 degrees in a turntable 29 to bring either chamber 21 near the spectrometer. A sample is introduced and melted in one chamber 21 while the sample in the other chamber is being analysed. One of the counter-electrodes 3 is used for melting and the other for the analysis, having turned the holder 22 through 180 degrees.

Title: Improvements in or relating to a process for producing diacetone alcohol
Filed: 1957-07-03
Abstract: Diacetone alcohol is prepared by condensing acetone by contacting it with a solid alkaline condensation catalyst, then removing the reaction liquid from contact with the catalyst before appreciable evolution of heat commences and thereafter allowing the reaction to proceed substantially in the absence of catalyst with consequential increase in the yield of diacetone alcohol. The reaction times for the two reaction stages are suitably 3 to 10 mins. and 1 to 3 hours respectively.  The catalyst may be, for example, sodium, potassium, calcium or barium hydroxide preferably in a porous inert material. The second reaction stage may be effected in a storage or buffer tank.  In an Example, acetone at 180 DEG  C. is passed at a specified rate through a cylindrical reactor containing asbestos sponge impregnated with caustic soda, without any appreciable evolution of heat and the issuing liquid, wherein 11% of the acetone is converted ,is stored for 2 hours whereby the conversion is increased to 13%. The final product is preferably freed of any traces of catalyst before being distilled, for example by exact neutralisation or by passage through a cation-exchanger.

Title: Improvements relating to pneumatic drying devices
IPC: F26B17/10
Filed: 1933-07-26
Abstract: 402,707. Pneumatic driers. ROSIN, P., 86, Bautznerstrasse, Dresden, Germany. July 26, 1933, No. 21082. Convention date, Aug. 27, 1932. [Class 34 (ii).] A pneumatic drier comprises a system of drying conduits in series or parallel, and a grading device, such as an air sifter, connected with each conduit, and arranged so that the larger particles are passed to the following conduit while the smaller particles are conveyed to a separator, each of said grading devices separating out larger particles than the preceding one. Heating gases are passed through the conduits, only one fan being required. The gases in the several drying branches may be at different and variable temperatures, obtained, for example, by the addition of cold air or waste gases in the parallel branches, or, in the series-connected branches, by adding fresh heating gases in each branch. The distribution of material to the various branches may be varied by means of control members in the air sifters. In one form, material is fed in by the device 17, and the fan 6 draws hot gases from the channel 7 through branches 1<1> and 1<11>, 21 and 2<11>, and 3. The lightest particles are separated from the remainder in sifter 8 and pass to the cyclone or other separator 5 through pipe 1<11>, the heavier material through feeding device 10 to the branch 2. A further sifting occurs in the device 11, the heaviest particles being passed to the last branch 3. The feeding devices 10 and 13 may be replaced by crushing devices, and the gas temperature may be varied by adjusting inlets 14 for cold air or the waste gases from the separator. In other forms, the branches 1, 2 and 3 may be straight; a cyclone separator may be provided for each drying stage ; and the conduits sifters and separators may be so arranged that the gases pass in series through all of the drying stages. The conduits may have one common insulation, and the sifters may be arranged in a single casing. The pipes 1, 2 and 3 may have different diameters to correspond with the distribution of the material, and the gas velocity may be controlled by throttle valves 15.
