Abstract: 961,138. Capacitors. COMMUNICATIONS PATENTS Ltd. Oct. 17, 1960 [July 16, 1959], No. 24518/59. Heading H1M. [Also in Division H4] An electrode of a dielectric heating equipment is spatially mounted from a support from which it is electrically insulated and there is arranged between the electrode and the support a conductive plate which is insulated from the mounting and provides with the electrode a capacitance in series with. the electrode system and the H.F. source energizing it. An upper electrode assembly comprises a box of polystyrene suspended from a carrier plate 9 of the thrust column of the equipment. The bottom wall 23 of the box has secured to its upper face a metal plate 27 to which is screwed the upper electrode 29. A second metal plate 38 forms with the first a capacitance which may be varied by variation of the spacing of the plates on rotation of an indexed control knob 37. The knob is fixed to a shaft 36 protruding into the box and bearing a helically grooved boss 35 into the groove of which engages a pin 33 mounted on a polystyrene block 32 which carries the second plate 38. Thus as the boss is rotated the block 32 moves axially on a further pin 31 affixed to the top of the box, so varying the spacing of the plates. Capacitive coupling between the H.F. energy source and the electrode system may also or instead be provided by a flexible lead comprising strips of copper foil separated by polythene, the whole being sheathed with fibreglass, and it is stated that a capacitor so constructed may be made variable, e.g. by relative sliding movement of the strips to provide varying overlap between them.

Abstract: 679,925. Feeding webs; collapsable spindles. MORGARDSHAMMARS MEKANISKA VERKSTADS AKTIEBOLAG. Sept. 23, 1949 [Dec. 6, 1948], No. 24541/49. Class 100 (i). [Also in Groups IX and XXIX] A reel for coiling strip and wire material comprises segments adapted to be expanded and contracted as a consequence of changes of the pressure in a chamber for a hydraulic pressure medium provided in the reel, plungers displaceable from or toward the centre of the reel being provided to transmit the pressure in said chamber to the segments. The reel 1 comprises a. plurality of cylindrically shaped segments 4 arranged between plates 5 secured to a driving shaft 6, adjacent edges of the segments having interengageable teeth 9. Each segment 4 is movable outwards by plungers 11 engaging plates 14, the segment being guided radially by projections 7 engaging grooves 8 in the plates 5. The shaft 6 itself forms a chamber 10 containing a suitable pressure medium such as oil, supplied thereto through an injector valve 15. The oil is compressed by a rod 19 to cause the segments 4 through outward movement of the plungers 11 to be moved into an expanded position determined by abutting surfaces 7<SP>1</SP>, 8'. The rod 19 is slidably mounted in a sealing gland 20, and its opposite end is connected through a coupling to a piston rod having a piston displaceable in a cylinder. The piston is displaced to move the rod 19 towards the reel by the introduction of oil to the upper side of the piston. The segments may be returned to their contracted position when the desired quantity of material has been wound on to the reel by springs 37 secured at its ends to the shaft 6 and the segments 4. The end of a strip or wire may be attached to the reel prior to a winding operation by a movable clamping jaw 30 which engages a clamping jaw 32 secured to a segment 4 when a plunger 33 having a head 34 is moved outwardly by the plungers 11. The jaw 30 may be moved inwardly to unclamp the strip or wire by a resilient member 36.

Patent GB-695812-A (GB)
Title: Improvements in or relating to methods and apparatus for the recovery of condensableconstituents from hot gaseous mixtures
IPC: B01D53/12
Filed: 1950-10-09
Abstract: <PICT:0695812/III/1> <PICT:0695812/III/2> <PICT:0695812/III/3> In the removal of a condensable constituent, e.g. water vapour, from a hot gaseous mixture, the gas is conducted along a confined course and is contacted countercurrently at two separate points with different sectors of a circulating stream of a solid granular adsorbent for the constituent in a manner forming a sequence of shallow, fluidized beds, the hot gas mixture being cooled at a third point, intermediate of the two separate points along its confined course.  As applied to the drying of hot combustion gases in the isolation of nitrogen oxides from the combustion gases of a nitrogen fixation furnace, the gases are passed in countercurrent to a solid drying agent, e.g. silica gel, in tower 21, then through cooled catalyst chambers 131, 132 where nitric oxide is oxidized to nitrogen dioxide and finally in countercurrent to a solid adsorbent for the nitrogen dioxide, e.g. silica or titania gel or carbon, in tower 140.  The tower 21 is divided into three processing chambers, viz. a drying chamber 24, a desorbing chamber 25 and an adsorbent cooling chamber 26, the chambers being separated by valve mechanism 28 (Fig. 3) which is adapted to pass solids but prevent admixture of gases between the chambers.  Solids enter the tower at 39 from hopper 38 and leave at 41 when they are recirculated to the hopper by airlift circuit 44. The chambers are divided into compartments by perforated plates 30 on which shallow fluidized beds are formed, the adsorbent moving from one compartment to the next below through downspouts 32 which are provided with closure means 34 (Fig. 3) adapted to open under a certain weight of adsorbent.  The hot combustion gases enter chamber 25 at 20 wherein they strip the adsorbent of moisture and leave the chamber at 77.  They are then passed through the upper chamber 79 of a tower 80 where they are showered with cooling liquid, e.g. water or brine.  The cooling water is gas-cooled in lower chamber 88 and recirculated to the upper chamber through line 98.  Cooled combustion gases are then passed through conduit 99 to the adsorbent chamber 24, which is provided with heat exchange coils 105, the gases in the upper part being cooled to a lower temperature.  Cooling of the adsorbent in lower chamber 26 is effected by a gaseous medium. Operation of tower 140 is similar in principle to that of tower 21. It is divided into two chambers, viz. an upper chamber 142 in which the gases are cooled and nitrogen dioxide is adsorbed and a lower chamber 143 in which the adsorbent is stripped of nitrogen dioxide by contact with a hot gas, e.g. hot nitrogen dioxide, the chambers being separated by a modified valve mechanism 145 (Fig. 5).
