Title: Crystalline hydrated phosphates
IPC: C11D1/14
Filed: 1961-08-30
Abstract: A water-soluble hydrated crystalline product in the form of crystals of a hydrated trisodium phosphate containing a higher alkyl sulphuric acid ester or a salt thereof present within the crystalline structure of said crystals.  The salt is preferably sodium lauryl sulphate and the hydrated trisodium phosphate may be chlorinated. The crystalline product is produced by crystallization from a hot solution containing hydrated trisodium phosphate and sodium lauryl sulphate or disodium phosphate, sodium hydroxide, sodium hypochlorite and sodium lauryl sulphate, depending on the product required.  The shape of the crystal thus formed depends on the proportion of sodium lauryl sulphate and the mode of crystallization. Rod-shaped crystals having a hexagonal cross-section and a longitudinally extending tubular passageway therein are produced when 0.001-0.10% by weight of sodium lauryl sulphate is added to the hot solution which is subsequently allowed to cool undisturbed.  Needle-shaped crystals having a hexagonal cross-section are produced when 0.001-0.3% by weight of sodium lauryl sulphate is added to the hot solution which is then agitated during cooling.  Needle-shaped hydrated crystals containing a large proportion of sodium lauryl sulphate can be produced by crystallizing trisodium phosphate dodecahydrate and sodium lauryl sulphate in the presence of no more moisture than is required to produce the water of crystallization. Potassium permanganate may be incorporated in any of the above crystals as colouring matter.ALSO:A water-soluble hydrated crystalline product for use in detergent compositions comprises crystals of a hydrated trisodium phosphate containing a higher alkyl sulphuric acid ester or a salt thereof present within the crystalline structure of said crystals.

Abstract: 1401274 Volume determination J G GISBY 6 July 1972 [6 July 1971 14 Feb 1972] 31640/71 Headings G1W and G 1X The volume of a package &c. is measured by means of a device comprising a first scale having a family of hyperbolas thereon, and a second scale consisting of a family of curves (which term includes straight lines). One face of the package is abutted against the first scale 21, Fig. 1, and the position of point 29 noted with respect to the hyperbolas having constants 2, 4, 6 &c. A cursor 27 may then be placed in position shown adjacent an opposite face of the package. The intersection of the cursor 27 with the correct straight line 26 giving the package volume, the correct line 26 being numbered the same as the hyperbola on which is the point 29 (i.e. 4 as shown). By using a modified device, Fig. 2, the weight of a package is determined by a weighing machine 33 and indicated on a dial 34. A slider 48 moves over a potentiometer wire 47 so as to give an electrical output determined by the package weight. Similarly a pointer 46' on a cursor 43 is movable over a potentiometer wire 45 line 39 numbered the same as the line 36 on which is the point 29 to give an output determined by the package volume. In a further embodiment, Fig. 4, an extension scale 73 is used when a package is too large for scale 70. The volume encompassed by length L is measured as before, the extra length I being measured on scale 73 or by tape 73'. This extra length l selects a vertical line on an extended scale of wall 71, and its bisection with a line 76, which is determined by point 79' as before, giving the total volume of the package on scale 78. Lines 76 and scale 78 may be drawn to a smaller scale (x 2 as shown). Alternatively, lines 76 may be replaced by a family of parabolas and the scale 78 altered accordingly.

Title: Semiconductor integrated device
IPC: H01L21/762
Filed: 1971-07-07
Abstract: 1364676 Semi-conductor devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 7 July 1971 [10 July 1970] 31839/71 Heading H1K Islands containing circuit components of a monolithic integrated circuit are provided in an epitaxial layer 2 and are isolated from the substrate 1 carrying the layer 2 by at least one P-N junction and from each other by isolation zones each of which includes an inset layer 20 of insulating material formed by chemical conversion of the semi-conductor material. The layer 20, e.g. of silicon oxide when the semiconductor in silicon, is countersunk into the epitaxial layer 2, but extends only partly through the layer 2 towards the substrate 1. Preferably its upper surface is substantially flush with that of the layer 2, and this is achieved by selectively etching a recess in the layer 2 through a nitride/oxide mask and then oxidizing the material within the recess. The inset layer 20 may, as shown, extend down to the depletion region 21 associated with a P-N junction between the substrate 1 and the epitaxial layer 2. Alternatively the lateral isolation of the islands may be completed below the inset insulating layer 20 by P-N junctions associated with buried layers provided between the substrate 1 and the layer 2 and/or formed within the layer 2 by depositing that layer in two stages and prediffusing dopant for the isolation zone after the first stage. Island isolation may also be completed, particularly in the case where the sub strate and epitaxial layer are of the same conductivity type, by providing beneath each island a buried layer (101-103), Fig. 9 (not shown), of the opposite conductivity type, the periphery of which layer contacts the inset insulating layer (109). It is possible to provide an interconnection channel between two adjacent islands separated by an inset insulating layer (109) by causing one of these buried layers (102) to extend beneath both islands as well as beneath the particular layer (109). The circuit illustrated in Fig. 3, includes a bipolar transistor 25, an MIS transistor 26, a diode 27 and a resistor 28. Certain of the diffused regions within these devices terminate laterally at the inset insulating layers 20, this having the advantage of reducing the space requirements of the structure. Schottky barrier devices and junction-gate FETs are also referred to.
