Inventor: BERG LEO
IPC: B01D1/14
Filed: 1968-11-07
Abstract: 1,193,559. Evaporators, spray type; concentration of solutions. KNAPSACK A.G. 7 Nov., 1968 [20 Dec., 1967], No. 52855/68. Heading B1B. A solution, e.g. a salt solution, is concentrated by spraying it through nozzles 15 .. 18 into a vertical tube 1 through which hot combustion gases are flowing from inlet 4 to a separator 2 and outlet 20. The solution flows from the separator 2 into receiver 3. The solution to be concentrated is supplied to receiver 3 through line 8. Some of the solution in receiver 3 is pumped through pipeline 10 to nozzles 15 .. 18, and some is pumped through pipeline 9 so that it enters the upper end of tube 1 tangentially and flows as a helical film down the inner wall. Concentrated solution is withdrawn from the apparatus through line 24. Receiver 3 is provided with a heater 25 to prevent the deposition of solid from the solution.

Abstract: 1477700 Aerials THOMSON-CSF 19 Dec 1974 [21 Dec 1973] 55029/74 Heading H4A An omnidirectional antenna for radiating a vertically polarized wave comprises a waveguide having oblong cross-section, a longitudinal plane of symmetry cutting the cross-section across the smaller dimension thereof, and two symmetrically arranged arrays of slots on each shorter side of the waveguide; a device is located within the waveguide to reduce the cut-off frequency thereof. In the embodiment of Fig. 1, slots 2 and 3 &c. are arranged opposite each other to operate in phase but the successive distances separating slots are varied in intervals ranging from #g/ 4  to 2#g where #g is the waveguide wavelength, to enable the required radiation pattern to be achieved. So that the distance between opposite slots is roughly #/2 where # is the operating wavelength, ridges 5 and 6 are employed along the waveguide to reduce its effective longer dimension without increasing the cut-off frequency of the waveguide. Metal plates 7 and 8 are provided along the length of the central plane of symmetry to promote the production of an omnidirectional pattern. In another embodiment, Fig. 2 (not shown) the waveguide is filled with a dielectric (9) instead of ridges 5 and 6 for the same purpose of allowing reducing dimensions for a given cut-off frequency. In a practical realization the slots are inclined to a greater or lesser extent according to the admissable percentage of horizontally polarized wave.

Other sheets, e.g. metal foils or paper, may be attached during the process. If a thermoplastics sheet is to be bonded to each surface of the base sheet a heating element may be located adjacent each platen. If the sheets of the laminate are bigger than the platens, they may be laminated in stages the sheets being moved appropriately after each section has been laminated. In Fig. 1, a press comprises upper press platen A which is hollow and through which heating or cooling medium, e.g. steam or water, may be passed by means of pipe connections 20, and lower press platen, the platens being pressed together with a pressure of 60-80 p.s.i. by hydraulic ram C.
