Title: Improvements in method and apparatus for conditioning pulverulent or granular material
IPC: B01F33/40
Filed: 1959-04-13
Abstract: 844,593. Mixing pulverulent materials. FULLER CO. April 13, 1959 [May 20, 1958], No. 12435/59. Class 86 In apparatus for blending dry pulverulent materials, e.g. mixes of raw materials prepared for the production of hydraulic cement, by inducing a circulation of the materials within a silo or bin in fluidizing and aerating streams of air or gas, steps are taken to avoid the compacting of a central cone of material as occurs in the known construction. This construction employs an aerating floor divided into sections, each section being selected in rotation to receive an air supply sufficient for fluidizing whilst the other sections receive air sufficient only to produce a mild aeration of the bottom parts of the superposed columns of material. It has been found that a central cone of compacted material is formed which prevents efficient blending of the mix. To avoid this, the aerating units 6, Fig. 2, arranged, as previously, as a floor and in a number, say four; sections, are connected to manifolds 9 by pipes 15, the inner units of the section each being provided with an additional pipe 15<SP>a</SP> whereby the supply of air to the central zone of units is greater than that to the outer zone. Each section is independently supplied with air. In operation, the section selected, in the cycle of selections, is supplied through its outer units with air sufficient to fluidize the superposed column of material, and through its inner units with a greater quantity of air to prevent the formation of a central compact cone. The remaining sections are supplied through the outer units with air sufficient to aerate the lower parts of the superposed columns so that the material flows over the units 6 from the areas of mild aeration into the area of fluidization, this being caused by the top of the fluidized column flowing over on to the tops of the other columns and increasing the pressure head on the lower parts thereof. In some circumstances, air entrapped in the material may be sufficient to allow the mild aeration in the non-selected sections to be discontinued. In a modification, the aerating floor is divided into sections each supplied from a box-like space beneath it, a central space receiving greater quantities of air than the mild aerating spaces. The air may be supplied in pulses as described in Specification 804,014.

In a modification intersecting partitions may be formed of one or more plies of the material on edge, the corners being strengthened by posts of layers of the material. The fibres of the pile may be of mohair, wool or artificial silk.
Patent GB-993336-A (GB)
Title: Fluid position sensor
IPC: F15B5/00
Filed: 1963-03-29
Abstract: 993, 336. Determining angles. SPERRY RAND CORPORATION. March 29, 1963 [April 11, 1962], No. 12546/63. Heading G1X. [Also in Division B3] A lathe bed 11, Fig. 1, 2, contains ports 12, each of which communicates with a fluid amplifier 13 by conduits 14. A tool carriage 10 movable on the bed carries a bar 15 containing ports 16, each of which is connected to a source of pressurized fluid via a conduit 18. Ports 12, Fig. 4, may be spaced so that their diameters overlap in the direction of movement of bar 15, so that when one of the ports 12 is aligned with its respective port 16 in bar 15, thus supplying full pressure through this port, the next port 12 is partially aligned with its respective port 16, thus supplying a partial pressure through that port. The transmission of these pressures to fluid amplifiers can control the positioning of carriage 10 by means of servomechanisms. Ports 12 may be arranged so that a greater overlap, or not overlap is provided. In a modification, Figs. 6 and 7, the angular rotation of a lathe headstock shaft 24 is sensed or measured by ports 21 in a non rotary cylinder, which co-operate with ports 25 located in a bar 23 rotatable with the shaft. Advantage can also be taken of the axial spacing of ports 21 by moving the cylinder 20 axially. In a further modification the angular rotation of shaft 30, Figs. 8 and 9, is measured by ports 33 in a plate 32, which co-operate with ports 34 carried by a bar 31 rotatable with shaft 30. Each port 33 lies in a different segment 1, 2, 3 &c. and the ports have an angular overlap with each other due to the increase of the port size, according to the distance of the port from shaft 30. To maintain the same maximum pressure in each port 33 the output channels 36 from the ports are reduced to the size of channel 36 1 . The pressure may be maintained by supplying each port 34 from a different source of fluid at a different pressure. In a modification the ports supplying the fluid are stationary and the output ports are movable. In a further modification fluid is supplied at a point between the output ports, and the control circuitry with a plate having a row of ports is passed over the output ports to uncover them one at a time.

Abstract: 1,134,019. Semi-conductor devices. ALLMANNA SVENSKA ELEKTRISKA A.B. 24 March, 1966 [25 March, 1965], No. 13003/66. Heading H1K. A semi-conductor device comprises a discshaped semi-conductor body having at least two junctions, the disc being considerably thicker at the edge than in the remaining part, and the edge being shaped so that a positive bevel angle is obtained at at least two of the junctions. The bevel angle is positive if the angle between the plane of the junction and the surface of the more lightly doped region is acute. In the SCR illustrated in Fig. 2 and in an SCR having an alternative edge configuration, Fig. 3 (not shown), P-type regions 2 and 4 are more highly doped than N-type region 3 so that bevel angles α 1  α 2 , are both positive. When either junction is reverse biased the depletion layer extends approximately to a thickness w so that distances a and b should be approximately equal to w to produce the required reduction in surface field-stress. A contact 8 may be applied to region 3 and connected to a bias supply which maintains both junctions reverse biased when the device is non-conducting as described in Specification 1,132,824. A dielectric layer may be applied to the edge surface of the disc. Layer 2 may be short-circuited to layer 1 by a metallic surface layer (not shown).
