Title: Methods and apparatus for the manufacture of corrugated board
IPC: B29C63/00
Filed: 1970-08-28
Abstract: 1324862 Corrugated board A E EDKVIST 28 Aug 1970 [29 Aug 1969] 41497/70 Heading B5N Corrugated board is produced by joining together at least one liner layer and a corrugated layer by passing them between rolls rotatable about their longitudinal axes, a molten material, which is solid at room temperature being applied to the surface of,the liner layer or layers and/or to the surface of the corrugated layer before they are contacted by the rotatable rolls by directing the molten material to move freely on to the surface or surfaces of the layers. The molten material may be applied by spraying or spattering. In Fig. 1 liner layers 1 and 2 are passed over guide rolls 6 to the gap between layer joining rolls 7 between which they are joined to intermediate layer 3 brought to corrugated form 5 by means of interengaging heated toothed rolls 4. Molten material is sprayed on to the surfaces of liner layers 1 and 2 facing corrugated layer 5 and also on to the surfaces of corrugated layer 5 facing liner layers 1 and 2 by spraying units 8 disposed in chamber 12 the air of which is heated by means of thermostat-controlled resistance elements 13. Prior to passing through rolls 4, layer 3 may be rendered water resistant by spraying with a molten material by means of spraying units 9, and the outer surfaces of the finished board may be rendered water resistant by spraying by means of spraying units 10 and given smooth surfaces by means of smooth rolls 11. In an alternative arrangement the molten material is applied to one of the liner layers in a first station, urged against the corrugated layer 1 by means of a roll which is kept pressed against a toothed roll for forming the corrugations, molten material applied to a second liner layer in a second station and the second liner layer urged against the corrugated layer between the layer joining rolls.

Title: Phosphate fertilizer products and processes therefor
IPC: C01B25/41
Filed: 1969-08-20
Abstract: 1282131 Potassium polyphosphate products; orthophosphate mixtures PENNZOIL UNITED Inc 20 Aug 1969 [27 Aug 1968] 41581/69 Heading C1A A polyphosphate composition is obtained by heating potassium dihydrogen phosphate (KH 2 PO 4 ) and potassium monohydrogen phosphate (K 2 HPO 4 ) at a temp. in the region 250 to 850 C., where the molar ratio of said KH 2 PO 4  and K 2 HPO 4  in the original reaction mixture is expressed by the relationship where n is an integer ranging from 5-20. The composition is said to comprise potassium tripolyphosphate and a novel potassium polyphosphate called for convenience an "anhydrophosphate" which is characterized as containing straight polymer chains and being distinct from the potassium metaphosphate obtained by heating potassium dihydrogen phosphate alone. The water solubility, the molecular weight, and the X-ray pattern of the mixture change with changing value of n, and the so-called anhydrophosphate may be obtained by dissolving out the potassium tripolyphosphate also present e.g. with cold water. The mixture of  orthophosphates required as starting material for the present process may be obtained by treating phosphate rock, or a partially or completely solubilized phosphoric acid reaction product of phosphate rock with phosphoric acid or a mixture of phosphoric and sulphuric acid, in the presence of potassium bisulphate and/or potassium sulphate at a temp. of 50 to 125 C., removing the calcium sulphate formed. The polyphosphate product mixture finds employment as a fertilizer.

Abstract: 910,034. Electric data-storage apparatus. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 16, 1960 [Dec. 19, 1959], No. 43393/60. Class 106 (1). [Also in Group XL (b)] A data storage apparatus, Fig. 7, comprises two shift registers X, Y and a number of storage pulse generators 17-25. In the basic form of storage generator, Figs. 2 and 3, a magnetic storage ring 1 has windings 7, 8, 9. A firing pulse at 4 will produce a rectangular output pulse at 5, provided that at some time prior to the receipt of the firing pulse a cocking pulse has been received at 3. The apparatus of Fig. 7 uses generators requiring two coincident pulses for cocking. Circulating shift register X is started upon receipt of the pulse p at t 0  and delivers pulses in sequence at t1 at terminals 11, 12, 13. Also at t 1  code group elements are received at a, b, c. If the first code group received at t 1  is 101, units 17 and 19 are cocked. If the next group is 001 (at t 1 ) unit 22 is cocked. A trigger pulse A at t 5  sets circulating register Y in operation to deliver pulses at t 0  sequentially at terminals 14, 15, 16. Thus signals stored in the columns I, II, III are sequentially read out. Receipt of a pulse q stops the action of registers X and Y after all the stored characters have been read out. The shift registers, Fig. 10 (not shown), are of known type; details of their operation is given in the Specification.

The mask 13, Fig. 5, may be of the grid type, with elongate apertures 13a which are 0À13 mm. wide at the centre of the mask and 0À09 mm. wide at the edge, and the light source 16 may also be elongate parallel to the apertures and disposed at the two positions Z1 and Z2 for the exposure. At the centre of the screen the areas exposed from the two positions are much the same, whereas at the edges they are displaced and form a wider exposed area to compensate for the narrower mask aperture. The light source may be moved continuously or in two stages between positions Z1 and Z2, which may be 2 mm. apart. The lighthouse (Fig. 10, not shown) may include means for moving the light from Z1 to Z2, and also means for moving the light transversely to expose other areas of the screen for the deposition of other colour phosphors; it may also include a lens 14 and filter 15. The apertures in the mesh need not be continuous but may be interrupted by bridge portions adapted to reduce vibration (Fig. 11, not shown); if the light source is elongate, the exposed area will still be a continuous stripe.
