Abstract: 1,159,145. Measuring liquid level electrically; liquid level indication. K.D.G. INSTRUMENTS Ltd. Nov. 2, 1966 [Aug. 5, 1965], No.33560/65. Headings G1H and G1N. In the measurement of liquid level, a pressure sensitive fluid control device controls the flow of fluid from an input, connected to a fluid source, to an output according to a first pressure, e.g. that above the liquid, such that the pressure at the input is indicative of this first pressure and an electric transducer senses the difference between this pressure at the input and a second pressure, e.g. that at the bottom of the tank. The output of a differential transformer (68-70, Fig. 3, not shown), in a unit 12, Fig. 1, and hence the reading of an indicator 15, is determined by the flexing of a diaphragm (62), carrying the transformer core (66), of which one face is exposed to liquid pressure at the bottom of a tank 10 whilst the other face is exposed to the pressure in a pipe 22 "Tee'd-off" from the connection between a constant flow air supply device 17 and a bleed outlet 19 controlled by a second diaphragm (27, Fig.2, not shown), exposed to the pressure above the liquid. The reading on the indicator is thus indicative of the depth or level of liquid in the tank 10.

Abstract: 364,751. Wrapping and labelling machines. SCHWEIZERISCHE INDUSTRIE GES., Neuhausen, Schaffhausen, Switzerland. Nov. 11, 1930, No. 33960. Convention date, Nov. 11, 1929. [Class 94 (i).] Cylindrical bodies or circular or oval biscuits or tablets arranged in piles are enclosed in a wrapper folded at the ends as shown in Fig. 14, and a label is applied to secure the folds. The article 1 is fed into position I above a plunger 2, Fig. 1, and beneath a wrapper 9. A plunger 10 is then in its lower position, and rises in conjunction with the plunger 2 to carry the article to position II, where the sides of a frame 14, Figs. 1 and 3, apply the wrapper to the sides of the article and leave two depending flaps 28, 29. Spring-pressed holders 16 in the frame are now allowed, by their operating levers 19, to approach the ends of the article under the action of springs 18, and a folder 26 raises the flap 28 against the underside. The frame then moves to position III carrying the article and wrapper with it and folding up the flap 29 against the edge 30. The holders 16 are withdrawn from the ends of the article and a forked folder 41 rises and makes folds 42, Fig. 11, in the projecting ends of the wrapper. Folders 44 form folds 43, Fig. 12, and plungers 37, 38 co-operate to carry the packet to position IV, Fig. 1. During the ascent, fixed folders 48, 49 make the folds 46, 47, Fig. 13, or a single folder may be used to make a broad fold. The article is now in a frame 52 on a slide 53, and is conveyed to the right, Fig. 1, by the reciprocation of the slide, past a fixed folder 56, which turns down the flap 57, Fig. 14. The articles are conveyed from the wrapping devices by a conveyer bar 59 actuated to move in a rectangular path. The bar is provided with holders 60, to prevent the articles from rolling or rubbing. The articles are labelled at the ends by the apparatus shown in Fig. 6. Labels are withdrawn from the bottom of a magazine 80 by a pneumatic suction plate 82 pivoted at 84, which presents the edge of the lowermost of the pile to grippers 85. The grippers carry the label into position over a container 86 for adhesive, or for water if the labels are already gummed. Prior to this, a series of fingers 92 have been caused to descend through apertures in the top of the container and to rise to the position shown. They then descend and deposit adhesive on the label, which is next carried by the grippers 85 further to the left and deposited on a pivoted flap 93, unaided by an independent frame 94. One flap and frame turn upwards about their pivot 95 and apply the label to the end folds of the package. The frame 94 is pressed by a spring against the flap 93 so as to yield when contact with the end of the packet is made. The flap may be fitted with a resistance coil so as to dry the adhesive.

Title: Improvements in and relating to the treatment of gases
Inventor: HEINRICH DIETER OTTO
IPC: B03C3/013
Filed: 1961-09-26
Abstract: A process for treating waste gases of an industrial plant (prior to passing the gases into an electrostatic precipitator) to reduce the electrical resistivity of the dust particles to 1010 ohm. cm. or less comprises the steps of burning fuel having a high sulphur content (i.e. 2% by weight or more) in an auxiliary combustion chamber in the presence of a supply of oxygen in excess of that required to promote complete combustion to promote the formation of 0,025 to 0,050 volume per cent of sulphur trioxide in the combustion gases produced therein, and passing the combustion gases so produced into the waste gas issuing from the industrial plant, so that the dust particles adsorb sulphur trioxide from said combustion gases.  In a modification, when the waste gases contain excess dust or when the combustion gases do not contain sufficient sulphur trioxide to permit adsorption of sulphur trioxide by all dust particles, the process is assisted by humidifying the dust.  The auxiliary combustion chamber may be an ordinary fire base grate or an oil-fired furnace, but preferably is a coal fired furnace with an automatic travelling grate, an essential feature of all these grates and furnaces being an ample flow of oxygen to the combustion zone.  Coal and oil having high sulphur content is burned in the furnace, especially hard coal containing pyrites mixed with any number of high sulphur content materials, e.g. pyrites, impure iron sulphate and elemental sulphur. The combustion gases are then mixed with the waste gases.  In the modified process the auxiliary furnace is the heating means for a low pressure boiler.  Sufficient steam and atomized water (water at 95 DEG -99 DEG C.) are mixed with the combustion gases passing through the flue and this gas mixture then introduced into the waste gases from the industrial plant.  The invention can be applied to electrostatic precipitators associated with cement furnaces or to calcium carbonate, magnesite, dolomite, bauxite and similar calcining plants, to ore-sintering plants, converter plants, and to other industrial wastegas producing plants.
