Title: Improvements in centrifugal driers
IPC: B04B5/10
Filed: 1920-12-17
Abstract: 176,903. Hoyle, H. P. Dec. 17, 1920. Addition to 164,506. Strainer separators.-The drying-machine described in the parent Specification is combined with a disintegrator mounted upon the shaft carrying the screen. The shaft 1 carries a spider 3, the arms 5 of which act as fan blades, and also support the wedge wire screen 4. Another set of fan blades 7 is carried by the top of the screen 4. The sleeve 14 carries the drum 15 with the helix 16, which has an increasing pitch in the downward direction. The casing is in four parts 27, 28, 29, 30; the part 29 has an inclined circular duct for the separated water, and the part 30 carries bars 32 with rings 33 riveted thereto. These bars with the bars 9 on the cylinder 8 form the disintegrator. Wet coal enters through the shoot 35 and travels down the helix 16 while being thrown against the screen 4 and the water extracted. The helix 16 rotates at a lower speed than the screen 4. The drying process is assisted by a current of air produced by the fan blades 5, 7. The coal falls upon the revolving bars 9 and is broken up, and drops into the hopper 34. In a modification the disintegrator consists of two conical parts with inclined serrations.

Filed: 1946-12-02
Abstract: 618,753. Lasting open-toed shoes. KAMBORIAN, J. S. Dec. 2, 1946, No. 35640. [Classes 17 (i) and 17 (ii)] In lasting a shoe wherein the upper 1 has an opening 9 at the toe end above the level of the foot supporting surface of the shoe bottom structure, spaced right and left terminal portions at the forward end of the upper are brought together and secured and the opening 9 thereby formed is engaged with the tip 11 of a last 10 having an insole assembled thereon. Rearwardly directed lasting stress to conform the forepart to the shape of the last is then applied to the aligned upper, and this is maintained during the remainder of usual lasting operations, e.g. by engaging an ankle strap 4 about the heel of the last. If the last tip is too blunt to enter the toe opening 9 a separate auxiliary tip piece 11 a, Fig. 6, may be attached to its forward end. Specification 541,643 is referred to.

Patent GB-832124-A (GB)
Title: Purification of isophorone
Inventor: CRAVEN ERNEST CECIL
Filed: 1957-11-21
Abstract: Crude isophorone is decolorized by contacting it with an acid type of fuller's earth at an elevated temperature and recovering the isophorone by distillation.  The fuller's earth must be such that 2 gms. thereof suspended in 100 c.cs. of distilled water imparts to the water a pH below 7.0.  According to one suitable procedure, the fuller's earth is added to the crude isophorone which is then boiled under reflux conditions, suitably under reduced pressure, and thereafter fractionally distilled; if desired these two steps may be carried out simultaneously. Another method comprises percolating the crude isophorone through a heated column of the earth and then distilling the treated isophorone.  Contact temperatures of 90-150 DEG  C. are preferred. Either or both steps of the process may be effected continuously. The decolorization may be partial or complete and may be combined with other purification treatments.  The crude material may be obtained by heating acetone under pressure in the presence of alkali.  Examples are given illustrating each of the above procedures and comparative experiments show the less effective use of alkaline fuller's earth.

Title: Improvements relating to electro-luminescent materials
IPC: H05B33/14
Filed: 1953-12-31
Abstract: 742,355. Electroluminescent materials. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 31, 1953 [Dec. 31, 1952], No. 36354/53. Drawings to Specification. Class 39 (1). Electroluminescent copper activated zinc aluminium sulphide is prepared by firing in an atmosphere of hydrogen sulphide containing from 0.01-20 per cent of an oxygen-containing gas, the copper content of the mixture before firing being 0.1-0.4 per cent by weight of zinc sulphide and the aluminium 25-250 mol. per cent of the copper. The oxygen-containing gas may be water vapour, air, CO 2  or SO 2 . The Cu and A1 are added as nitrates, sulphates, chlorides &c. The fired powder may be washed with NaCN (5 per cent) to remove excess copper sulphide. In preparing the material, mixtures of ZnS and ZnO may be used in place of pure ZnS or even ZnO converted into the sulphide by heating in pure H 2 S. Air or CO 2  may be added to the stream of H 2 S for the phosphor firing atmosphere by slow displacement in a flask admitting water and subsequently freezing out the water vapour at -57‹ C. The Specification includes a number of examples in which the presence of large quantities of oxygen give blue electroluminescence, whilst small quantities give green. The phosphors are convertible by reheating in the appropriate atmosphere. The presence of aluminium gives a stable green electroluminescence unaffected by frequency shift. Specification 734,652 is referred to,

Abstract: 804,007. Axial-flow compressors. BRISTOL AERO-ENGINES, Ltd. Dec. 6, 1956 [Dec. 23, 1955], No. 36978/55. Classes 110 (1) and 110 (3). In a bladed disc-and-drum compressor rotor comprising blade-carrying disc elements and tubular elements connected together to form a disc-and-drum structure, the elements together bound, at least in part, a number of internal chambers in the rotor, at least some of the chambers being substantially sealed from one another internally of the rotor and defined in part each by a different adjacent pair of the elements which are jointed at an interface in flat face-to-face contact with one another around substantially the whole of the periphery of the drum, and at least one of the elements has a slot in its joint face, the slot forming a passage for venting the chamber to the outside of the drum. In the compressor rotor shown in Fig. 1a, the discs 12, 21, 22 ... have abutting flanges 12a, 21a, 21b, 22a, 22b ... and are connected together by bolts 29 passing through holes in the abutting flanges. Slots 74, Figs. 1a and 3, cut in the abutment faces of the abutting flanges, allow the discs to be separated during dismantling by inserting wedge-shaped tools into the slots. Three such slots may be provided equally spaced around each flange, holes 75, Fig. 1a, being provided in spacer rings 35 opposite each slot to enable the tools to be inserted. The holes 75 and slots 74 provide communication between each rotor chamber 70, 71 ... and the working passage of the compressor, so that the pressures in the chambers are graded in accordance with the stageby-stage rise of pressure through the compressor, the unbalanced endwise pressure loading on the discs 21, 22 ... therefore always being towards the inlet end of the rotor. The endwise loads on the discs are transmitted through tubular members 68, 47 and 39, rotor discs 11 and 12, and a spigot 13 to a bearing 14. Slots similar to the slots 74 may be provided in the abutment faces of rotor discs 24, 25 (not shown) and of a labyrinth seal member 76 (not shown) to facilitate separation of those parts. In other respects the rotor is as described in Specification 781,478.

Title: Process for the production of a cast iron mold for the shaping of glass
Inventor: MOORE WILLIAM HENRY
IPC: C03B9/48
Filed: 1967-08-16
Abstract: 1,149,461. Moulds for glass. W. H. MOORE and C. A. GREEN. 16 Aug. 1967, No. 37585/67. Heading C1M. [Also in Division B3] A cast-iron mould for shaping glass, e.g. into bottles, is made by measuring the chill value of a bath of molten cast-iron, adding a modularizing agent to increase the value 10- 75% and then casting the iron in a mould having a chill, e.g. an iron or steel casting, at a position corresponding to the working face of the glass-shaping mould so that it has a layer 11 comprising graphite in nodular form adjacent the chill and another layer 14 comprising flake graphite. The nodular layer 11 may be spaced from the face 10 of the glass-shaping mould but this surface is machined in any ease so that the final face has the layer at the surface. There is a layer 12 comprising undercooled graphite between layers 11 and 14. The nodularizing agent may be Mg, Ce, Y, La or Nd or other rare earth metals or combinations of rare earth metals, e.g. mischmetal, or magnesium silicon. The casting is annealed to remove carbides, produce the nodular graphite at the surface and provide a ferritic matrix. A pearlitic matrix may be obtained by adding alloying agents such as Cr, Mo, V or Cu. Agents such as Ni and Al may be used. The iron may be graphitized particularly before nodularization by the addition of silicon, calcium silicide or ferro-silicon.
