Title: Apparatus for conveying articles whilst undergoing treatment in a succession of stages
IPC: B65G49/04
Filed: 1954-05-17
Abstract: 782,829. Rotary conveyers. McCARTHY, H. A., and STRUCKMAN, E. May 17, 1955 [May 17, 1954], No. 14362/54. Class 78 (1). In apparatus for conveying articles while undergoing treatment in a series of baths arranged in a circle of the kind comprising a carrier which receives a step-by-step motion to carry the articles above each bath in turn and an up-and-down reciprocating motion to immerse them in and remove them from the baths, the articles are supported on the carrier in separate groups which are immersed simultaneously in different baths. The articles are suspended by hooks from bars 4 mounted at the free ends of radial arms 2 attached to a pillar 6 which is rotated to convey them above a circular tank B. The tank is divided by radial walls into compartments, the number of which is twice that of the arms 2. The length of each bar 4 is greater than the width of a compartment so that it rests on the walls as the pillar 6 approaches its lowest position. In this position the bars effect the switching-on of the current used in the treatment of the articles. A lost-motion connection 5 is provided between the bracket 3 and arm 2 to allow relative movement of these parts after the bars have come to rest. The pillar 6 is supported by a platform 7 which is movable vertically in guides 9 and supported by cords 19 passed over winding drums 20. The shaft 21 of the drums is driven alternately in opposite directions by a reversible electric motor 22 controlled by switches 25 and 26 at the terminal positions of the platform which are actuated by tappets on the platform. The pillar is rotated by an electric motor 10 through worm gearing 11, 11a and is stopped with the arms in the position shown in Fig. 2 by the actuation of a switch 13, Fig. 3, by one of a series of projections 15 on an interchangeable ring 16. The number of projections on the ring corresponds with the number of dippings which the articles are to be given. The actuation of the switch 13 deenergizes the motor 10 and energizes the motor 22. When the switch 26 is actuated to deenergize the motor 22, this motor remains deenergized until a time-lag device starts it in reverse.

Patent GB-612169-A (GB)
Title: Improvements in or relating to the bleaching of fatty oils and fats
IPC: C11B3/00
Filed: 1946-05-15
Abstract: Dark-coloured fatty oils and fats are bleached by intimately mixing them with an acidic phosphoric compound and oxygen in the presence of an inorganic silicon compound consisting of hydrated silica gel, hydrated amorphous silica (wet ground), a silicic acid, or fluo-silicic acid, the last two named types of compound being either preformed or formed in situ under the conditions of treatment.  The acidic phosphoric compound may be a phosphoric acid or a salt of a phosphoric acid having an acid reaction.  The oxygen may be intimately mixed with the oil or fat by blowing air therethrough and the proportion of inorganic silicon compound used may be from 0.1 per cent to 5 per cent of the weight of the oil or fat.  The proportion of acidic phosphoric compound used may be from 0.25 per cent to 3 per cent by weight of the oil or fat and the process may be carried out at a temperature between 40 DEG  and 100 DEG  C.  The process may be followed by separation of the treated stock from the treating agents and the further bleaching of the stock with a bleaching earth.  The silicon compound may be any silicic acid such as metasilicic acid or fluosilicic acid and may be formed in situ from a salt thereof, preferably an alkali or alkaline earth metal salt such as sodium silicate, magnesium p  silicate or sodium fluosilicate.  The inorganic silicon compound may be added to the fat in the form of a slurry or a solution prepared with a small amount of water.  The acidic phosphoric compound may also be included in the slurry.  The oxygen may be the commercial gas or may be furnished by an oxygen-liberating compound such as sodium hypochlorite, sodium chlorite or hydrogen peroxide, present to the amount of 0.01 per cent to 2 per cent by weight based on the oil or fat to be treated.  The acidic phosphoric compound used may be commercial orthophosphoric acid of 70 to 85 per cent concentration, pyrophosphoric acid, potassium or sodium dihydrogen phosphate or disodium dihydrogen pyrophosphate.  Bleaching earth may be mixed with the stock at the same time as the phosphoric acidic compound and the inorganic silicon compound.  In an example, a mixture of a very dark tallow, 1.5 per cent by weight of 85 per cent phosphoric acid and 6 per cent by weight of a 20 per cent aqueous solution of sodium silicate are mixed at a temperature of about 65 DEG  C. and blown with air for 2 hours at this temperature.  The stock is then settled, washed free from all chemicals with hot water, bleached with an activated bleaching earth and filtered.  In another example, the bleached fat is made into soap and in a third the soap is also bleached with sodium hydrosulphite. Specification 577,879 is referred to.

Title: Device for controlling the level of a radiation emitting liquid
IPC: G01F23/292
Filed: 1975-04-10
Abstract: 1479224 Detecting molten liquid level CEDA SpA 10 April 1975 [26 Sept 1974 (2)] 14775/75 Heading G1A [Also in Division G3]  In a device for monitoring and controlling the level, 16 to 17, of a hot infrared radiation emitting molten liquid flowing from a ladle 10 into a hole 21 of an ingot mould 14, the surface of the molten liquid is monitored at an angle by the device. Thus the level of the liquid determines the amount of radiation passing through elongated apertures 23, 23' Fig. 3, in front of photo-diodes 26, 26'. As the liquid level increases or decreases between the maximum and minimum levels 16 or 17, more or less of the liquid surface comes into view over the top of side 15 of the hole 21. The outputs from the photo-cells 26, 26', Fig. 4, supply a normalization or temperature correction circuit 38 or 38'. This circuit also receives a signal from a further photo-diode 126 or 126' behind a punctiform aperture 33, 33' positioned to always view the liquid surface and thereby receive a constant known amount of radiation for any particular temperature. The output of the normalization circuit 38 or 38' is connected to a switch 39 or 39' which will only allow the normalized signal to pass when there is a signal from a still further photo-cell 226 or 226' positioned behind aperture 133 or 133' to receive radiation from the central stream of liquid flowing from the hole 11 to the hole 21. The signal from switch 33 or 39' passes to an indicator 40, which illuminates one of a number of lights 41, 42 or 49 depending upon the level. The signal also passes to a comparator 43 where it is compared with a pre-set signal from a potentiometer 44. The comparator 43's output provides a control signal for a power circuit 47 that activates a motor 48 which effects the withdrawal of liquid from the ingot mould 14. A continuous signal is supplied from a circuit 45 and potentiometer 46 to ensure that there is always a miniumum signal present which is supplied to the power circuit 47. Instead of a photo-diode 26 behind the elongated aperture a row of photo-cells, Figs. 5 and 6, (not shown) may be provided in the beam paths, and the number illuminated will be proportional to the liquid level. Several modifications of the optical systems are described.
