Abstract: 1,236,318. Pneumatic conveyers. BUHLER A.G. GEB. 28 May, 1969 [5 June, 1968], No. 27066/69. Heading B8A. Apparatus for transferring bulk material between enclosures 11, 13<SP>1</SP> at different pressures, through an intermediate chamber 15, comprises a flow control flap unit 2 associated with a through flow aperture 12 between each enclosure and the chamber, each unit including a closure element 45 having a pressure compensating aperture 50 therein, a shut-off element 35 for selectively opening and closing the aperture 50, and power means for draining the shut off element 35, the closure element 45 being freely movable between the element 35 and through flow aperture. The shut-off element 35 is adjustably pivotally mounted to an arm 31 rigidly mounted to a spindle 3, and the closure element 45 is adjustably pivotally mounted to an arm 41 rotatably mounted on the spindle 3, whereby anti-clockwise rotation of the spindle 3 finally causes the element 35 to close the aperture 50 via a seal 51, and secondly causes the element 45 to be pushed to close the aperture 12 via a seal 23. Clockwise rotation of the spindle 3 opens the aperture 50, whereby air pressures between the enclosure 11 and chamber 15 are balanced, after which the material in the enclosure 11 gravitationally opens the element 45. The spindles 3, 3<SP>1</SP> of the two flap units are interconnected by a pneumatic ram which in sequence opens one flap while the other is closed, the air pressure supply to the ram being controlled either manually or automatically on a time cycle.

Patent GB-786453-A (GB)
Title: Means and method of supporting the helix in travelling wave tubes
IPC: H01J23/26
Filed: 1955-09-30
Abstract: 786,453. Travelling-wave tubes. STANDARD TELEPHONES & CABLES, Ltd. Sept. 30, 1955 [Oct. 7, 1954], No. 27898/55. Class 39(1). In a travelling-wave tube the helix is carried by three or more ceramic support rods and the assembly is held under tension by short rings, a long tube, or a helix of glass which are thermally deformed and then shrunk on to the assembly, the deformation producing an approximately triangular cross section of the glass element or a polygonal cross section if there are more than three support rods. The glass members are preferably of Corning 7052 borosilicate glass which softens at 708‹C. In one form short glass rings or a long glass tube 17, Fig. 4, are slipped over the helix-support rod assembly 10c, 11c and heated to above their softening point to cause deformation to the cross-section 18 shown in Fig. 5, so that on cooling the glass rings or tube shrinks on to the assembly. The heating of the glass rings or tube is effected by a radiant heater in an atmosphere of hydrogen or by an open flame in air ; the latter is however less desirable since it causes oxide deposits on the helix which have subsequently to be removed. In a further form, Fig. 6, the helix and support rod assembly 10d, 11d are rotated by a slow speed lathe 20 and a ribbon of glass is passed over an open name 22. The flame travels axially so that the glass can be wrapped around the assembly in a helix. The heat causes the glass ribbon to take up a triangular envelope (see Fig. 5) as it is being wound on the rods. On cooling the glass helix is shrunk on to the helix. This operation can be carried out in air since the flame does not touch the helix. The helix may have end sections of increasing pitch for impedance matching and the tube envelope may be of glass, quartz or metal.

Title: Improvements in and relating to olefine oxides
Inventor: STEEL DEREK KENNETH VINCENT
IPC: C07D301/32
Filed: 1960-08-15
Abstract: An olefine oxide is extracted from a mixture thereof with one or more halohydrocarbons by contacting the mixture with water so that the olefine oxide and light halohydrocarbons separate into liquid and vapour phases respectively and then distilling the liquid phase to give the olefine oxide. The halohydrocarbons used are defined as "heavy" if due to involatility they remain in the liquid phase and "light" if they form a vapour phase.  The halohydrocarbons occur in olefine oxides if, for example, they are prepared by the dehydrohalogenation of halohydrins. The process may be carried out continuously and is suitable for the treatment of olefine oxides e.g. propyleneoxide or ethylene oxide containing up to 10% by volume of halohydrocarbon.
