Title: Improved process and apparatus for pre-treating grain before conditioning
IPC: B02B1/08
Filed: 1952-03-24
Abstract: 721,772. Treating grain. MIAG MUHLENBAU UND INDUSTRIE GES. March 24, 1952. [March 24, 1951] No. 7518/52. Class 58. In a process for pre-treating grain before conditioning the grain is conveyed pneumatically towards the conditioner and is subjected to the action of heat and/or moisture whilst suspended within the gaseous conveying medium. As shown a grain washer 1 which includes a centrifuge (not shown) delivers the grain suspended in a gaseous carrier into a pipe-line 3 of a pneumatic conveyer the delivery end of which is formed by a separator 4 which separates the grain from the gaseous carrier, the grain then passing into the conditioner 2 whilst the separated air is re-cycled into the centrifuge of the washer 1 and blown against the grain to assist the separation of the water therefrom. Means (not shown) are provided for heating and/or moistening the gaseous carrier so that the grain is subjected to the action of heat and/or moisture while it is suspended therein. According to a modification (Fig. 2 not shown) a steam conveyer screw is disposed between the centrifugal separator and the conditioner, the separated grain being delivered to and conveyed by the screw into the conditioner and being subjected on its way through the screw conveyer to the action of steam. In another modification shown by chain-dotted lines in Fig. 1 the grain arrives through the pipe-line 3 of the pneumatic conveyer where it is subjected as described above to the action of heat and/or moisture and is then separated from the gaseous carrier within the separator 4 and delivered by the latter to a stone separator 7 which discharges the grain into a washer 1 comprising a centrifuge, the gas from the separator being introduced into the washer to assist the separation of the grain from the water and the gas may then be recycled to the start of a pipe-line 3 whilst the grain cooled in the washer moves into the mechanical steam screw conveyer 6 where it is heated again before it enters the conditioner 2.

Title: Improvements in and relating to wireless signalling systems
IPC: H03B5/10
Filed: 1919-03-26
Abstract: 139,640. British Thomson - Houston Co., (General Electric Co.). March 26, 1919. Electric oscillations, producing.-A thermionic oscillation-generator is connected to an aerial in such a way that the capacity of the aerial is' compensated. In systems in which the generator is connected direct to the aerial, the ratio of the. inductance and capacity in the generator circuits is, for a given tuning, largely determined by the capacity of the aerial; but, by the present arrangement, this ratio may be adjusted to the value at which the oscillator works most efficiently. The filament 2 of the oscillator is connected to the grounded mid-point of an inductance 7, and the plate 3 and grid 4 are connected to opposite sides of the same inductance, which acts as a coupling between the grid and plate circuits. The aerial 5 is connected to the plate side of the inductance 7, and its capacity, which may be represented by an imaginary condenser 16, is compensated by a corresponding condenser 17 connected across the grid side of the inductance 7. The plate circuit is tuned by a condenser 9, and the direct-current supply circuit includes a choke-coil 19 designed to be resonant to the oscillation frequency so as to act as a substantially infinite impedance to the oscillations. For telephony, the grid circuit is controlled by a microphone through an audio-frequency transformer 21, Fig. 2, the secondary of which is shunted by a condenser which passes the oscillations, and an audio-frequency chokecoil 23 is included in the direct-current supply circuit.

Title: Improvements in or relating to aerials for metric, decimetric or centimetric waves, of flat form and capable of being applied to flat surfaces
IPC: H01Q13/20
Filed: 1956-03-15
Abstract: 798,821. Aerials. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. March 15, 1956 [March 17, 1955], No. 8208/56. Class 40 (7). An aerial arrangement of flat form, and therefore particularly useful for mounting on aircraft, comprises a transmission line for the energy to be radiated the structure of which is such that its cross-section is not completely surrounded by conductive material and there are sudden variations along its length causing sudden impedance variations which act as radiation sources. In one form the line may consist of a dielectric plate 1 provided with a metallic coating 2 on all its sides except for a channel on the top surface which extends round fingers 3, 31, 4, 41, 5, 5<SP>1</SP>, attached alternately to opposite edges. To produce radiating impedance variations as required by the invention a variety of arrangements may be used. For example the width of the channel at the end of certain fingers may be reduced as at 7 and 7<SP>1</SP>. In another arrangement the width of the channels between the fingers and the finger widths are reduced over short lengths of the line (Fig. 4, not shown). In a further arrangement the lengths of the fingers are reduced and the edge coatings to which they are attached are brought closer together (Fig. 5, not shown). If the line is located inside a metal casing which is open at the front, spaced shielding plates extending at intervals across the front of the line and attached to the sides of the casing may be used to produce the discontinuities (Fig. 6, not shown). The dielectric in the line may be a solid or it may be air, in the latter case the conductive parts require to be more robust as shown in the construction of Fig. 3. This Figure also shows how the transmission line may be fed from a coaxial feeder 24 by insulating one of the fingers 13 of the line from the other conductive parts of the line and connecting the inner conductor 25 of the feeder to this finger. Fig. 11 shows a different type of transmission line in which a ceramic plate 31 has a metal plate 40 on its underside and a narrow metallic band 32 on its upper side. Radiation may be obtained by reducing the width of the strip as shown at e<SP>2</SP>, or by introducing sharp turns in the band. In another arrangement the band is supported above the base plate by spaced supports having a high dielectric constant which themselves form the radiating discontinuities.

Filed: 1933-03-18
Abstract: The process of the parent Specification and Specification 396,575, for esterifying cellulose in the presence of sulphur dioxide, a nonsolvent for the product, and perchloric acid or its salts as catalyst, while maintaining the temperature below about 40 DEG  C., is modified by avoiding the use of the non-solvent and the limitation of the temperature to below 40 DEG  C.  The esterification solution after neutralization of the catalyst, and if desired, addition of further quantities of solvent, may be used directly in the production of artificial silk, films, plastic masses, and the like.  In an example cotton linters pretreated in acetic acid are treated with a mixture comprising acetic anhydride, acetic acid, sulphur dioxide, and perchloric acid.  After neutralizing the catalyst, the product is precipitated with water, or cyclohexanol acetate.  Pretreatment may take place in the presence of sulphur dioxide and a part or whole of the perchloric acid, and in the preparation of mixed esters, esterifying acids such as nitric acid and formic acid may also be present.
