Title: Apparatus for  handling articles
IPC: A24C5/35
Filed: 1972-07-21
Abstract: 1404144 Apparatus for dividing a stream of rod-like articles; push-plate type endless conveyers MOLINS Ltd 21 July 1972 39409/73 Divided out of 1404141 Headings B8C and B8A Apparatus for separating a leading end portion of a stream 173 of articles from said stream comprises means to feed the stream of articles along a defined path, a first fixed track 176 having an end at a first level, a second fixed track 178 having an end at a second level, a movable track 180 movable from the first level to the second level, means for moving separating means 174 along the tracks, the tracks being positioned with the second fixed track closer to the defined path than the first fixed track so that the separating means is clear of the stream while it is moving along the first fixed track and is projected through the stream while it is moving along the movable track during movement of the latter from the first level to the second level, the separating means, when moving between the first and second tracks having a first component of movement due to its motion along the movable track and a second component of movement due to movement of the movable track between the first and second planes. As shown, the stream of cigarettes 173 is fed forward by a conveyer 170 which consists of a pair of chains 171, 171, which carry between them surface forming slots 172 to support the stream of cigarettes 173, selected slats 172a being provided with a slot through which the corresponding plate 174 can pass. The inner end of each plate 174 carries a pair of rollers 175 which are adapted to run along corresponding fixed upper, and lower, guide rails 178, 176 respectively and along movable guide rail sections 180, 181. The latter are carried by respective parallel linkages 189 which are pivotable respectively by cam-mechanisms 196, 198 and 192, 194 to move the guide rails 180, 181 up-and-down between aligned positions with the upper and lower guide rails 178, 176. In operation, as the conveyer 172 advances the stream 173 of cigarettes and as the rollers 175 of each plate 174 are transferred from the fixed guide rail 176 to the movable guide rail 180 in alignment therewith, the guide rail 180 is raised by the cam-mechanism 196 198 so that the respective divider plate 174, is progressively raised through the stream of cigarettes until the guide rail 180 becomes aligned with the upper, fixed, guide rail 178. In the latter position the plate 174 extends completely through the stream 173. When a batch, separated by a pair of plates 174 along the upper guide rail 178, coincides with a compartment in a packing container the conveyer 170 is stopped and the batch is transferred into the said compartment. The plates 174 are successively retracted by the movable guide track 181, which is correspondingly lowered by the cam mechanism 192, 194 during the stepwise movement of the conveyer 170, to transfer the rollers 175 into engagement again with the lower fixed rail 176.

Title: Purification of aluminium sulphate
IPC: C01F7/748
Filed: 1963-10-08
Abstract: <PICT:0995209/C1/1> Aqueous aluminium sulphate containing as impurities iron and at least one of titanium and zirconium is purified by (1) adding an oxidizing agent to convert Fe++ to Fe+++, (2) mixing with agitation the oxidized product with a water-insoluble amine anion exchanger to extract the impurities, (3) separating and recovering the purified aqueous aluminium sulphate, (4) reactivating the amine anion exchanger by contacting it with aqueous sulphuric acid (\sF6% conc.), (5) then treating it to reduce the sulphate content to 25% or less based on the weight of amine ion exchanger, (6) recycling the treated ion exchanger to step 1.  Oxidizing agents used in steps (1) may be NaClO3, KMnO4, O3 or H2O2, preferably in amounts equivalent to Fe+ + present.  The H2O2 if used is preferably 3% by weight, possibly containing a stabilizer, and is reacted pref. at about 45-60 DEG  C.  The amine anion exchangers used in step (2) may be Diaurylamine, triaurylamine, butyldiaurylamine, "Amberlite" LA-1 (Registered Trade Mark), and are preferably dissolved in an organic solvent, e.g. petroleum distillates, aliphatic and aromatic hydrocarbons, alcohols, kerosene, heavy naphtha, benzene. The conc. of exchanger is pref. 2-30%.  In step (2) the aqueous/organic phase ratio may be in the range 1 : 25 to 3 : 1. Step 5 may be carried out by washing with water.  For example, on the flow diagram, which illustrates counter-current extraction and regeneration, an aluminium sulphate liquor charge from the digestion of clay or bauxite containing iron, zirconium and titanium impurities leaves tank one via line 2, is admixed with 3% H2O2 from tank 3 introduced via line 30, and the oxidation is completed in tank 6. The oxidized mixture then flows, via line 7, through mixer settlers 8, 9, 10, 11 and 12 respectively countercurrent to an amine ion exchanger, e.g. Amberlite LA-1 dissolved in kerosene, introduced through line 35.  The purified aluminium sulphate solution is then passed through stripping towers 39 and 41 (e.g. packed with granular carbon) to remove kerosene. Pregnant amine ion exchanger solution passes from mixer settler 8 to mixer settlers 23, 24 where it is regenerated by a countercurrent stream of 10-15% H2SO4 introduced through line 43 and withdrawn through line 48.  The amine is then washed with water introduced from line 44 and withdrawn from line 45 to reduce the sulphate content to 12% based on the weight of the amine. The regenerated amine is then recycled via pump 33 and line 35.

Abstract: 1,165,936. Automatic frequency control. TELEFUNKEN PATENTVERWERTUNGS, G.m.b.H. 31 Aug., 1967 [9 Sept., 1966], No. 39840/67. Heading H3A. A swept frequency oscillator has one of the sweep limits stabilized by setting the limit to correspond to a null point of a comb filter, and providing means to derive from the filter output, a control signal dependent on the deviation of the limit from the null point frequency. As described, oscillator 1 is swept between limits f n  to f n+1  by a sawtooth signal which provides a period of constant frequency fn. This frequency is arranged to coincide with a null point of a delay line filter 5, and during the constant frequency period a gate 16 is opened to connect the filter output to a synchronous demodulator 13. The demodulator output 12 is fed to a varactor diode 20 which adjusts the oscillator frequency. In order to provide the synchronous detection, the oscillator output is also fed to the demodulator via a variable 90 degree phase shifter which may be set up when the switch 15 is in the position shown. In a modification Fig. 6 (not shown), the set up facilities for the phase shifter are omitted and the filter output is amplified before being applied to the demodulator.

Title: Method and apparatus for electrostatically applying multi-coatings
IPC: B05B5/08
Filed: 1958-12-11
Abstract: <PICT:0911298/III/1> Electrostatic coating-apparatus comprises an atomizer array including at least one centrifugal atomizer head, and at least one electrostatic deflector, and means for creating an electrostatic field between the array and the articles being coated, the atomizer head and the deflector being positioned relative each other and to the articles to provide an effective fan-shaped spray pattern emanating from only a part of the peripheral edge of the atomizer head, and for electrostatically depositing the spray on the articles.  The electrostatic deflector may be rotatable during the spraying operation and it may itself constitute a spraying head.  As shown in Fig. 1, articles 31 are carried around an earthed conveyer 30 and subjected to the spray pattern from a pair of rotary atomizer heads 38 and 40.  These are mounted on insulated shafts 42 and 44 of drive motors 50 and 52, mounted with relatively adjustable spacing on a bracket 54.  The bracket 54 is connected in a tiltable manner to a piston 58 which is reciprocated vertically by an hydraulic cylinder 60 between limits set by switches 64 and 65.  Coating material is supplied to the atomizer heads 38 and 40 from a supply 72 through conduits 73 and 74, connected to feed tubes 75 and 76, and they are charged to a high voltage by a source 100.  When supplied with coating material, each atomizer provides a spray of material and repels atomized material from the neighbouring head, so that particles are provided from one position only of the edge of each atomizer. Differently coloured coating-materials may be fed to the atomizers.  If no coating material is supplied to one of the heads, it simply functions as a deflector, the rotation providing a cleaning action.  Three heads may be mounted on a common bracket, in linear or triangular formation, and their edges may lie in the same or in different planes.  Suitable heads are shown in Figs. 3 and 4.  In Fig. 3, coating material is fed by a tube 75 to a well 102 of the ring 103 and escapes through openings 104 on to the inner surface of the head and is urged centrifugally to the atomizing edge 101.  In Fig. 4, coating material is fed by tube 105 on to a deflecting plate 106 before being urged centrifugally to the edge 101.

Title: Production of calcium silicate fillers
IPC: C09C1/28
Filed: 1961-11-09
Abstract: Calcium silicate fillers which are amorphous to X-rays and have a CaO : SiO2 ratio of between 1 : 4 and 1 : 30 are produced by mixing with stirring calcium silicate, having a CaO : SiO2 ratio of between 1 : 1 to 1 : 3.5, with "active silicic acid." The calcium silicate may be formed in situ by reacting milk of lime directly with "active silicic acid." However, unless the reaction is carried out rapidly when the concentration reaches a value CaO : SiO2 of 1 : 1 to 1 : 3 hydrated calcium silicates with a tobermorite-like structure are formed. Alternatively calcium silicate is prepared by the action of water glass solution, Na2O3.3SiO2, on calcium chloride solution, which is subsequently reacted with "active silicic acid."  The "active silicic acid" used is preferably formed from water glass solution by reacting with acid or hydrogen exchange resins and preferably have a concentration of 5% and a pH value of 2-3.  The calcium silicate fillers are used in the rubber and paper industries.
