Title: Mixing of particulate materials
IPC: B01F5/04
Filed: 1975-05-21
Abstract: 1514743 Mixing particulate material OCCIDENTAL PETROLEUM CORP 21 May 1975 [24 May 1974] 22023/75 Heading B1C In a method and apparatus for mixing particulate materials dispersed in respective fluid streams the first material is formed in a reaction zone into a swirling annulus flowing towards a mixing zone and the second stream supplied to within the annulus to flow in energy-exchanging relationship therewith. In an embodiment, Fig. 1, the first stream is introduced through an inlet 12 and formed into a vortex by vanes 28 and the second stream is introduced axially by a conduit 30, 22. The hollow tapering element 24 directs the first stream towards the periphery of the apparatus, the particles in the first stream being uniformly distributed by a screen 16. The vortex is destroyed by baffles 38 to promote mixing in the downstream section 36. In another arrangement (see Figs. 5 and 6, not shown) the vortex is formed by introducing the first stream through one or more tangential inlets. In an example relating to the gasification of caking coal the first stream consists of preheated char in nitrogen and the second stream is caking coal in steam. The char heats the coal but the streams remain unmixed until the coal has passed through the sticky stage in which it might adhere to the wall of the apparatus.

Title: Apparatus for use in tuning a musical instrument or voice with respect to a standard pitch
IPC: G01H3/00
Filed: 1975-05-22
Abstract: 1477254 Tuning musical instruments; pulse multiplying and dividing DAINI SEIKOSHA KK 22 May 1975 [24 May 1974] 22369/75 Headings C5J and G4D Apparatus for tuning a musical instrument includes a standard pitch generator A; a microphone or like circuit B for receiving tones from the instrument; and means 81 arranged to cause pulses from generate A to scan a row of. lamps 83 and pulses from circuit B to blank part of the row whereby if the instrument is not in tune with the standard pitch the blank part of row shifts giving an indication of mistuning as a visible light flow. The standard pitch generator A consists of an oscillator of about 4.3 MHz feeding a frequency divider 13 with diode gate circuit 34 arranged to produce notes in the chromatic scale selected by switches 21, 32. A slight change in the pitch can be produced by an additional oscillator 12 which inserts extra pulses by gate 1 la to the input of divider 13. If the inserted pulses are made longer than the pulses from oscillator 11 a proportion of them will "bridge" adjacent pulses from oscillator 11 to produce an effective reduction in frequency; if they are much shorter a proportion of them are inserted between adjacent pulses to increase the effective frequency. The output of the standard pitch generator is fed to a counter 15; a selected stage output of the counter is fed to an amplifier 16 and speaker 16a to sound the selected pitch in a selected octave. The pitch selector keys 21-32 and the octave selector keys 4a-4f are (Fig. 2 not shown) arranged along coordinate axes of a note matrix. The microphone circuit B comprises an amplifier 52; a low pass filter 53 to eliminate the harmonics; an A.G.C. circuit 55 and a Schmitt trigger 56 feeding octave dividers 57. A counter circuit 6 counts pulses from counter 15 (at nominally four times the frequency out of octave dividers 57) for the period of a pulse from 57 and is then reset repeatedly. Gates 69, 70 connect two lamps 74, 93 to the counter 6 such that if the counter always counts four exactly before being reset, i.e. when the notes are in tune, the lamps are extinguished; if the counter only occasionally reaches four or occasionally reaches five one or other of the lamps flashes to signify that the tone is higher or lower than the standard; if the counter never reaches four or always reaches five the respective lamp is lit continuously to signify a large error. The moving light display 83 provides for final fine tuning.

Filed: 1952-09-05
Abstract: 716,402. Printing surfaces. ALGRAPHY, Ltd. May 13, 1953 [Sept. 5, 1952], No. 22418/52. Class 100 (2) A lithographic printing plate comprises a plate formed wholly of, or having a surface coating of, aluminium or an aluminium alloy capable of having formed thereon by the process of anodizing, a hard resistant oxide coating, the printing surface being anodized and having the printing areas formed by copper or other ink accepting metal deposited on the anodic coating. To prepare the plate a plate of aluminium, for example, is cleaned and de-oxidized before being passed to an anodizing tank, the phosphoric acid process being preferred. After being anodized the p'ate is washed in water and transferred to a copper plating tank and after plating is again washed. The printing image is produced by forming a resistant coating over the image areas of the plate and etching to remove the copper from the unprotected areas. The plate is thus left with a copper deposit in the pores of the anodic coating over the image area. The resistant coating is then removed leaving a plate having the whole of its printing surface in a single plane.

Title: Thin film structures
IPC: H01L45/00
Filed: 1963-06-06
Abstract: 1,010,575. Tunnel devices. SPERRY RAND CORPORATION. June 6, 1963 [June 8, 1962], No. 22639/63. Drawings to Specification. Heading H1K. A thin film device, suitable for tunnelling comprises a film of vapour deposited aluminium oxide between two films of conductive material, one at leash of which is not aluminium; the aluminium oxide being " formed " by a prolonged application of a suitable voltage to increase the current density which it is capable of handling. One or both of the metal films may be of Au, Ag, Pt, Pa, Cu, Zn, Cd, Cr, Fe, Ni, Pb, Mg, Ti, Ta, Va, Co, W, Bi, and one of the films may be of Al. The deposition of the metal films either on a substrate in the first instance, or finally on the aluminium oxide film may be effected by vapour deposition. The aluminium oxide deposition is also effected by vapour deposition, pure aluminium being vaporized in an atmosphere of oxygen in which the deposition takes place. In one embodiment a 5000  film of Pb is evaporated on to a glass slide, followed by a 350  film of Al 2 O 3  followed by a further 5000  film of Pb, in the form of strips having various areas. On applying voltages of less than 12 V only small currents are obtained, but on reaching this voltage the current grows for a period of 45 sees. after which it remains constant and of the order of Ima. This is the " forming " process referred to above. After this process the current densities obtained are much larger and correspond to an " unformed " film of about <SP>1</SP>/ 7 th the thickness. If the film is left without impressed voltage for about an hour, then it requires to be reformed, although the process takes a shorter period. The effect is suggested to be due to the formation of a positive ionic space charge which drifts towards the cathode and lowers the work function thereat. The current is also stated to be temperature dependent, rising sharply with temperature above 250 K. An experiment is described for observing the relaxation of the space charge referred to above. A device in which gold is used for the outer films is also described in which the edges of the structure may be coated with SiO, or other insulating material.
