Title: Improvements in or relating to stacking and depositing apparatus for textile sheets particularly laundered material in laundries
IPC: B65H45/101
Filed: 1962-10-25
Abstract: 985,539. Folding fabric. W. WULFF. Oct. 25, 1962, No. 40370/62. Heading D1S. A stacking and depositing device,e.g. for long textile pieces, having conveyer belts guided over a rocker table pivotable about an axis and a feed table between end rollers, whereby the textile pieces are laid in zig-zag fashion by means of reciprocating movement of the rocker table is characterized in that between rotatably mounted rocker table arms, above and below the pivotal axis of the rocker table, guide rollers are mounted which lead the conveyer belts out of the plane of the feed table into that of the rocker table, the distance of each guide roller relative to the pivotal axis of the rocker table being so selected that the length of the conveyer belts guided over the rocker table remains constant during reciprocating movement of the rocker table and undue tensional stresses in the belt are avoided. In the arrangement shown endless conveyer belts 11 are guided over rollers 14,14a, 15 and 16. Rollers 14,14a and 15 are mounted on rocker arms 18,19 pivoted on shaft 17 so that the belts form a feed table 12 and a rocking table 20 for folding material in zigzag fashion on table 31. Mounted also on the arms 18,19 are guide rollers 22, 23 for belts 21 which are in contact with belt 11 or material thereon. The belts are driven from motor 24 which also drives the rocker arms 18,19 via levers 27 and crank drive 28. The reciprocating movement of table 20 folds textile piece 30 in zig-zag fashion on table 31. The latter is preferably provided with means for vertical adjustment in accordance with the weight of material deposited thereon. Such means can be by weight, springs, pneumatic or hydraulic means with hand or mechanical control means. Transverse stretching means may be provided above table 11 to effect transverse stretching of the textile piece prior to its being fed on to table 12. Such stretching means may comprise gripping jaws which are adjustable in a transverse direction on a cross-bar. Further conveyer means may be provided adjacent table 31 for transferring the folded textile pieces to, for example, a mangle.

Title: Non-heat-reactive, higher-alkylphenol resins as rubber tackifiers
IPC: C08L21/00
Filed: 1963-10-15
Abstract: Natural and synthetic rubbers (including ethylene-propylene and ethylene-propylenediene copolymers) are rendered more tacky in the uncured state by the addition of at least one non-heat reactive p-alkylphenol-formaldehyde novolak resin wherein the p-alkylphenol has the general formula <FORM:1011124/C3/1> where R is an isomeric alkyl group containing from 9 to 15 carbon atoms.  The term "isomeric" is defined as a branched chain alkyl group or, in the case of a mixture, which contains less than 50% of any one straight chain alkyl group.  Small proportions of lower alkylphenol-formaldehyde resins may be used in addition. The compositions may contain other ingredients such as petroleum oil, reclaim and carbon black. Conventional vulcanizing techniques are used.  Specifications 714,214 and 880,904 are referred to.

Abstract: 1478878 Mixing apparatus SECEMIA 20 Sept 1974 [1 Oct 1973] 41089/74 Heading BIC [Also in Division F2] A metering and mixing apparatus for bulk materials comprises a plurality of units, one for each constituent, each unit comprising a support 2, 3 having a sampling conveyor 7, and a drive member 17 for the sampling conveyor having a stepless speed adjuster. All the sampling conveyors discharge to a transfer conveyor 10; each support 2, 3 is adapted to be juxtaposed with other similar supports and with a drive unit 35 which drives all the sampling conveyor drive members 17 and also the transfer conveyor 10. The conveyors have continuous casings to isolate the materials from the atmosphere; as shown they are screw conveyors and the drive members 17 are antilump-formation devices connected to the conveyors through a shear-bolt 18. A sensor 19 detects clogging, while failure or falling off in the material supply is detected by hinged flaps 12 and sensors 13. The transfer conveyor may be a pneumatic conveyor; the common drive motor may have a speed adjuster to vary the total input without altering the proportions of the constituents. The speed adjuster for the sampling conveyors (see also Fig. 4, not shown and Division F2) comprises a crank 26 driving a compound connecting rod 30, 31, the pivot 30a of which is supported by a rod 32 the upper end of which has a control knob 5 moving in an arcuate slot (4), whereby the position of the pivot 30a, and consequently the throw of the end of the rod 31 may be varied. The device drives a freewheel device 22, thus giving the drive member 17 an intermittent rotary motion.

Title: Extraction of tungsten from tungsten-bearing ores
IPC: C22B34/36
Filed: 1963-10-22
Abstract: Tungsten values are extracted from an aqueous tungsten-bearing solution by adjusting the pH of the solution to pH5 or less, adding sufficient soluble fluoride or hydrofluoric acid to convert all the silica and phosphorus in the solution to SiF6 and PF6 anions, contacting the resulting solution with a solution of a water insoluble organic solvent and a salt of an amine which is capable of forming a water insoluble complex with the tungsten, thereby extracting the tungsten content into the organic phase, separating and washing the organic phase and contacting it with sufficient ammonium hydroxide solution to convert the tungsten to ammonium tungstate and to establish a pH of at least 7.5 in the aqueous solution containing it.  The tungsten-containing solution may be that obtained by heating a tungsten ore, e.g. scheelite, wolframite or hubnerite with sodium carbonate and/or sodium hydroxide, or a solution thereof, and leaching with water to dissolve sodium tungstate. When the solution contains Mo, As or Sb, preliminary purification is achieved by adding excess alkali metal and ammonium sulphide, adjusting the pH to between 2 and 3 with mineral acid and filtering the precipitated sulphides from the solution which is then suitable for fluoride treatment.  It is postulated that the formation of the SiF6 or PF6 anion prevents the formation of a silico- or phosphotungstic acid whose amine-complex is insoluble in the organic solvent.  Extraction into the organic solvent, e.g. kerosene preferably containing tri-butyl phosphate or di-isobutyl ketone and containing, preferably, a tertiary aliphatic amine sulphate is carried out suitably at about 40 DEG  C. in mixer settlers until the organic phase contains 10-15 g. WO3 per litre. The organic phase is washed with deionized or SiO2-free water prior to extraction with ammonium hydroxide solution, also SiO2-free or alternatively containing a small amount of ammonium fluoride or hydrofluoric acid. Preferably the ammonium hydroxide solution is recirculated, in one or two mixer-settler combinations, in contact with the organic solvent until the WO3 content of the aqueous phase is 9 to 15%.  The aqueous solution, clarified by filtration, is concentrated to e.g. one tenth volume and excess ammonia and water evolved are condensed for re-use after supplementing with fresh ammonia.  Insoluble ammonium paratungstate is filtered off, washed with distilled water and dried. 5-10% of the mother liquor is recycled to the concentration step. The organic solvent after the ammonia extraction is contacted with 0.1 N sulphuric acid solution and returned to the organic extraction stage, while the sulphuric acid layer may be used in the acidification stages.

Abstract: 1429628 Making battery grid plates ELECTRIC POWER STORAGE Ltd 12 Sept 1973 [14 Sept 1972] 42759/72 Heading B3A [Also in Division H1] A method of making a planar electric storage battery grid comprises distorting selected bars of an as-cast grid inwardly from an enveloping surface of the cast grid. A lead alloy grid is first cast in the form of a continuous strip using a part-cylindrical mould comprising an inner rotating cylindrical member provided with grooves for moulding the bars 11, 12, 15, 16, and a stationary part-cylindrical member. The formed grid is then flattened while hot and the bars are distorted to alter the shape of their cross-section. Thus, triangular-shaped bars 15, 16 are formed, and diamond and hexagonal bars 12, 10 are formed respectively using grooved rollers. The bars 12 extend from one enveloping surface of the grid to the other, whereas bars 15, 16 only extend from one surface a distance less than the maximum thickness of the grid represented by the thickness of the frame periphery 10. The bars 15, 16 gradually merge to the full thickness of the grid frame at points 17 where they join the bars 11.
