Title: Apparatus for admixing liquids
Inventor: HURLEY THOMAS FREDERICK
IPC: G05D11/13
Filed: 1950-02-17
Abstract: 687,285. Mixing liquids in proportionate Quantities. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 17, 1951 [Feb. 17, 1950], No. 4152/50. Class 86 [Also in Group XXVIII] A liquid to be admixed proportionately with a liquid flowing in a conduit is injected into the conduit by means of a positive displacement pump controlled in response to the displacement of a spring controlled gate acting as a flow responsive device in the conduit. In Fig. 1 the displacement of a gate 11 by the flow of liquid through the conduit 6 rotates a disc 13 around which is wrapped a flexible pull member 14 tensioned by a spring 16, the movements of the gate 11 thereby being transmitted to a lever 15 which forms part of a lost motion control mechanism by which means the cam 2 imparts to the diaphragm pump 1, a stroke of variable length. The added liquid enters the conduit 6 through a nozzle 8 downstream of the gate 11. The disc 13 could be replaced by a cam when required by the law of the flow responsive device and pump control mechanism. An indicator lamp 17 may be energized when the control lever 15 is displaced from its non-pumping position and a lamp 19 may be energized by a pressure differential device 20 to show whether liquid is actually being pumped. In Fig. 2, (not shown), the displacement of the member 14 rotates a sleeve valve arrangement which governs the effective pumping stroke of a pair of plungers of a variable displacement plunger pump. In another embodiment, Fig. 3, (not shown), the member 14 actuates a speed controller of an electric or fluid operated motor driving a constant displacement pump.

Title: Improvements in or relating to calcium sulphate ª-hemihydrate crystals
IPC: C04B11/02
Filed: 1966-02-01
Abstract: In the production of a -CaSO4. 1/2 H2O crystals by heating an aqueous suspension of CaSO4.2H2O of pH from 1.5-6 to a temperature within the range 105-125 DEG  C. under super-atmospheric pressure, the heating is carried out in such a manner that (a) the rate of temperature increase is reduced over the last 2-3 DEG C. below the recrystallization temperature, (b) during recrystallization heating is maintained but the temperature is allowed to fall, e.g. by 2-4 DEG C. owing to the endothermic reaction, and (c) the reaction medium is not contacted with a hot surface or fluid at a temperature above 135 DEG C.  The CaSO4.2H2O may be natural or synthetic, e.g. from the production of phosphoric, tartaric or citric acid from H2SO4 and the corresponding Ca compounds, and may be 20-80 mm  by 50-200 mm  in size.  It may be purified by elutriation preferably at above 50 DEG C., e.g. up to 90 DEG C., and the water used may contain Ca or Mg oxide, hydroxide, or carbonate, at a pH of 4.  Crystallization promoters may be used in the process, e.g. carboxymethyl cellulose, tetrapropylene benzene sulphonate, sulphite liquor, salts of malonic, maleic, succinic, citric, or tartaric acids, or hydrolysis products of keratin, casein, or proteins.  The rate of heating over the last 2-3 DEG C. may then be 5-10 min./ DEG C. (at pH 3-4) or 50 min./ DEG C. (at pH 2); otherwise it may be 6 hours for the 2-3 DEG C. 0.2% Al(OH)3 may also be added and seed crystals may be used. Heating may be effected using steam.  The liquor from the crystals may be recycled.  The product crystals may be of size 20-30 mm  by 40-60 mm .

Title: Improvements in the production of synthetic filaments by melt spinning
IPC: D01D5/092
Filed: 1963-11-14
Abstract: 998,664. Melt spinning artificial filaments. E. I. DU PONT DE NEMOURS & CO. Nov. 14, 1963 [Nov. 15, 1962], No. 45021/63. Heading B5B. In the production of artificial filaments by melt-spinning the extruded filaments are quenched while travelling down through a quenching zone across which flows a stream of a gaseous quenching medium, the quenching zone comprising an upper and a lower zone, the linear rate of flow of quenching medium across the lower zone being greater, e.g. by about 35%, than that across the upper zone. As shown, Figs. 1 and 2, a quenching apparatus 10 suitable for the above process is elongated vertically, is rectangular in cross-section, and is provided with an imperforate top, rear and side walls. It has an open front. At its lower rear end it communicates with a duct 12 through which quenching air at room or a lower temperature is introduced. A fine mesh diffusion screen 14 divides the apparatus 10 into a quenching chamber 10g through which the freshly extruded filaments travel from spinneret 16 to convergence guide 17 and a plenum chamber 10p into which the quenching medium is introduced from duct 12. The expression " plenum chamber " is defined as a chamber in which the pressure of the air is slightly above atmospheric. Chamber 10p is partitioned by a distribution plate 18 having relatively large and widely but uniformly spaced holes. Between screen 14 and plate 18, in close proximity to the screen, there is provided a perforated rigid plate 20 extending from top to bottom and from side to side of the chamber 10p. Plate 20 has uniformly distributed holes 22 in an upper zone and a substantially greater frequency of uniformly distributed holes 24 in a lower zone. Holes 22 and 24 are of equal size. The total area of the holes per square foot in the lower zone of the plate 20 is substantially greater, e.g. about 35% greater, than in the upper zone of the plate, and the flow rate of the quenching medium in the lower zone of the quenching chamber 10g is correspondingly greater than in its upper zone. The desired flow control may be achieved by substituting for plate 20 a partial screen adjacent to the top of chamber 10g or by providing a pattern of equally spaced holes in plate 20, the holes in the lower zone of the plate being larger than in the upper zone, but the arrangement shown is preferred. The invention reduces the number of broken filaments and draw roll wraps in subsequent stretching operations.

Abstract: 1,253,494. Semi-conductor devices; image pick-up tubes. SONY CORP. 2 Feb., 1970 [3 Feb., 1969], No. 4849/70. Headings H1D and H1K. A target for an image pick-up tube comprising an array of PN junctions J includes, in the form shown, a plurality of polycrystalline regions 10a formed in a vapour-deposited N-type layer 10 on an N-type substrate 8 due to the presence of " seeding sites " 9, e.g. of amorphous Si or SiO 2 , on the substrate surface, the junctions J subsequently being formed by diffusion of a P-type dopant through an oxide mask 11 into the polycrystalline regions 10a and hence into the immediately adjacent parts of the surrounding N-type monocrystalline material 10b and 8. Further N-type regions may be diffused into a central area of each polycrystalline region 10a to form an array of NPN devices. In addition buried P + type regions may be pre-diffused into the substrate 8 beneath each seeding site. In a modification (Fig. 5, not shown), the vapourdeposited layer (10<SP>1</SP>) is of P + -type conductivity, the substrate (8) still being N-type, and the polycrystalline deposition (10a<SP>1</SP>) occurs over a continuous seeding site (9<SP>1</SP>) interrupted by circular openings (9a<SP>1</SP>) over which monocrystalline material (10b<SP>1</SP>) is formed. An N-type isolation. diffusion is effected into the polycrystalline material (10a<SP>1</SP>) to define an array of P+ monocrystalline islands (12<SP>1</SP>) forming PN junctions (J) with the substrate (8). Further N- type diffusions may also be carried out in this case to provide an array of NPN devices.
