Title: Method and apparatus for pneumatically grading a powdered product
IPC: B03B4/06
Filed: 1967-02-23
Abstract: 1,137,375. Pneumatic separation. INSTTTUT DE RECHERCHES DE LA SIDERURGIE FRANCAISE. 23 Feb., 1967 [2 March, 1966], No. 8605/67. Heading B2H. Particles of a powdered product to be graded are fed from a hopper 1 via a conduit 4 into the lower portion of a chamber 2 of elongated rectangular form the bottom of which is constituted by a grid 9 through which air is fed by means of a blower 10 via a conduit 12 in such a manner that a fluidised layer 20 of particles is formed from which the finer particles are entrained by the rising air current to be discharged therewith at the top of the chamber 2 while the larger particles remain in suspension in the layer and travel in the direction of the arrow a towards a discharge aperture 22. The length of the chamber 2 is at least 6 times its width. The height of the aperture 22 above the level of the grid 9 is between 5 and 30 cm. so as to maintain the layer 20 at that thickness and the chamber space above the layer 20 is equal to at least 8 times that thickness. The chamber 2 is divided, by means of a partition 7 having an aperture 8 in its lower part, into at least two compartments 5, 6 which at their top are connected to cyclones 30, 34 in which the finer particles are separated from the entraining air and collected in the containers 32, 36. Very fine particles discharging from the cyclones with the air through a common conduit 31 are separated out in a dust-remover, not shown. To facilitate separation in the chamber 2 air is blown through a valved pipe 16 horizontally through the product at its entry into the chamber. Separation is further enhanced by deflectors 18, 19 and obstacles 21 which create turbulence. The air supply conduit 12 is connected to wind-boxes 11a-d which are obliquely set relative to the grid 9 to impart a horizontal component to the air to facilitate movement of the largest particles in the layer 20. This movement may also be facilitated by providing alternatively, or in addition, as shown, a grid comprising a double row of perforated sheets with offset apertures which impart the required horizontal component to the air. Alternatively, an inclined or stepped grid may be used. The air supply conduit 12 is equipped with flow measuring venturis 14 a-d and regulating valves 15 a-d which adjust the air speed so that it increases from the box 11a to the box 11d. Due to this increasing speed, the particles entrained into the cyclone 34 are of a greater size than those entrained into the cyclone 30. The larger particles discharged through the aperture 22 are led on to a conveyor belt 26 via a hopper 23 equipped with level-control indicators 24, 25.

Abstract: 1388387 lon-implantation into semi-conductors SMITHS INDUSTRIES Ltd 10 April 1972 [8 April 1971] 9136/71 Heading H1K Regions in a semi-conductor substrate 6 to which ohmic contact is to be made are formed by ion-implantation both through a window in an insulating layer 8 on the substrate 6 and through the part of the layer 8 which completely surrounds the window. Monoenergetic ions are used; this gives a higher surface doping level to the peripheral part of the region. Fig. 2 shows that part of an integrated circuit which contains an IGFET T and a resistor R. Boron ions are implanted into a (100) orientated N-type silicon substrate 6. Source and drain regions 3, 4 and resistor terminal regions 3, 4 are formed by the above process, the insulating layer 8 comprising a lower layer of thermal silicon oxide and an upper layer of silicon nitride, an aluminium layer (22, not present at the stage shown) having been used as an implantation mask. The shallow extensions 11, 12 of the source and drain regions are formed in a separate gateregistered implantation step; the channel region 13 of the resistor may be formed at the same time or at an earlier stage. The aluminium metallization used to form the gate electrode 9 and connections 14 is taken over thick silicon oxide walls 16 between devices to avoid the formation of parasitic channels. The many integrated circuits formed on the substrate are tested, separated and mounted on headers. Since the first process is the formation of insulating layer 8 and since it remains throughout the process and in the completed device, the structure is usefully tested for faults (such as pinholes) immediately after the formation of the layer 8.
