A wind tunnel comprises means producing a main gas stream in the test section, and, surrounding the main stream, at least one auxiliary tubular gas stream flowing in the same direction as, but at a lower velocity than the main gas stream. In the figure, a compressor delivers gas to the tunnel inlet nozzle 1, comprising a fixed wall 2 and a movable flexible wall 3, one end of which is anchored to a flap 4 pivotable about axis 7 by an hydraulic jack 7, and the other end of which is attached to a hydraulic jack 10 maintaining the wall under tension. The wall rests on a shaped member 5 movable by an hydraulic jack 8 connected to a lever pivoted to member 5 and to fixed structure at 6. The flow characteristics of the inlet nozzle may thus be adjusted. At the inlet to the test section 15, an annular chamber fed with gas under pressure from a duct B, surrounds the outlet of nozzle 1, and produces a tubular gas stream flowing along the walls 12 of the section, and into an annular collecting chamber 16 discharging into a duct C. The velocity of the tubular stream is half that of the main flow, whereby turbulance is reduced to a minimum. There may be a plurality of tubular streams, their velocities decreasing in radially outwards sequence. The divergence of walls 12 is adjustable by hydraulic jacks 14. The diffusor section 17 comprises a fixed wall 18 and a movable flexible wall 19 which is anchored at the diffusor inlet end and maintained under tension by connection to an hydraulic jack 26 at its downstream end. The wall rests on a shaped member 20 movable by a hydraulic jack 21. The diffuser characteristics may thus beadjusted, and may be adjusted simultaneously with the inlet nozzle characteristics. Apertures 22 provided in walls 18 and 19 are used for injecting gas into or withdrawing gas from the diffuser. The diffuser has a right angled bend at 23, and adjustable apertures are provided at 24 for the withdrawal of hot exhaust gases from rested jet engines. A pressure sensitive device is provided upstream of the inlet to nozzle 1 to adjust automatically the orientation of the compresser stator vanes, to keep the gas stream pressure constant. Mechanical, pneumatic, or electrical devices may be substituted for the hydraulic jacks.

Title: Improvements in or relating to transformers for high-frequency heating generators
IPC: H01F21/04
Filed: 1954-01-19
Abstract: 751,020. Transformers. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Jan. 19, 1954 [Jan. 22, 1953], No. 1595/54. Class 38 (2). An oil-immersed transformer supplying a high-frequency heating coil comprises an axially displaceable watercooled helical primary coil 5 surrounded by a coaxial cylindrical conducting shell 7 and surrounding a ferromagnetic ferrite core 19, the primary coil having a length more than twice its diameter and being so mounted that the oil can flow freely between the core and coil 5. The coil 5 and coil 19 with a mutual clearance of a few mm. are mounted on hard paper insulating rods 9, 11, 13 carried between insulating end plates 15, 17. These plates are carried by two bars 21, 23 which slide in fixed insulating supports 25, 27, which also carry the conducting shell 7. The coil 5, core 19 assembly is moved relative to the con. ducting shell 7, by rotation of handle 47 whose spindle carries a roller 49 on which are rolled the ends of bands 51, 53 which pass over rollers 57, 59 to join plates 15, 17. The conducting shell carries two terminal clamps 33, 35 and is cooled by tubes 43, 45 soldered to it, which carry water which may also pass through the hollow primary coil 5. To reduce the movement needed to remove the coil 5 from effective coupling with shell 7 when the output current is low, the lefthand part of the shell, separated from the other part by cut 63, may be removed from effective use after undoing screw 69 which holds its upper end 65 to the main part of the shell at 67. To contain the oil which transfers heat from core 19 to water-cooled winding 5, the transformer is mounted in a tank 3 of which the plate 1 which carries the transformer is a cover. In a modification the moving assembly may slide on a single bar in a hole along the core axis, in which hole may also lie a tubular connection to the primary coil, the self-induction of the connection being reduced by interrupting the core by an axial saw cut. The moving parts may be reduced in length if one end plate can enter the conducting shell, Figs. 3, 4 (not shown). Speoification 751,022 is referred to.

IPC: A23K10/28
Filed: 1924-01-21
Abstract: 232,667. Channer, C. E. Jan. 21, 1924. Bulk evaporators.-Sour milk or milk artificially soured by the addition of approximately 12 per cent sour-curds to final bulk is placed in trays on racks 8 in a chamber and its temperature raised to 104‹ F. for about two hours for completely covering and partially evaporating and cooking it. The heating is then increased, the temperature being raised to 200‹ F. until the milk dries to a brown granular mass which is them crushed in a mill. The heating is accomplished by a current of air which is forced through a steam heating device 9 by a fan 18. The heated air passes through a shaft 10 to ducts 11 at the base of the chamber 7 provided with openings 12. After circulating through the chamber the air flows through openings 13 into a central flue 14 and thence passes to the outer atmosphere or it may be again circulated through the heater. In a modification the soured milk may be heated in a steam-jacketed tank at 104‹ F. until it is fully curdled and its temperature is then raised to 200‹ F. until it assumes a pasty condition. The pasty mass is, transferred to a steamjacketed drying chamber where it is maintained at a temperature of 170‹ F. until it turns to a brown desiccated product which is then crushed to powder. Electric heating devices may replace the steam jackets on the tanks.
