Title: Containers for beds of fluidised particles and processes carried out in them
Inventor: REEVE LEWIS
IPC: B01J8/44
Filed: 1964-10-30
Abstract: To prevent corrosion of a metal distribution plate 2 through which gas is passed to fluidize a bed of solid particles, e.g. when purifying sand by fluidization by hydrogen chloride, a layer 7 of refractory material having apertures or interstices for the adequate distribution of the gas is placed on top of the plate. The layer may consist of a single block drilled with passages 6 which register with openings 3 in the plates, or alternatively the layer may be of broken refractory brick (Fig. 2, not shown). Metal strips 4 provided beneath the plate prevent solid particles falling through the plate. <PICT:1119250/C1/1>

Abstract: 966,247. Transformers. WESTINGHOUSE ELECTRIC CORPORATION. Dec. 28, 1961 [Jan. 5, 1961], No. 46484/61. Heading H1T. An electrical inductive apparatus, on which there is at least one winding 30, Fig. 1, has two magnetic core sections 32, 34 formed from two different magnetic materials such that the coercive force of core section 34 is several times larger than that of the other, the winding being disposed so that when current flows therethrough a magnetic flux is produced in both of the core sections. Alternatively, the cores 82, 84, Fig. 4, may be of similar materials, and in a further modification, Fig. 12 (not shown), separate transformers may be employed. Each of the core sections 34, 84 has one or more gaps 36, 86 filled with a non-magnetic substance such as air. One of the core sections may be made of sheet material having a first preferred direction of orientation lengthwise of the sheet and a second one perpendicular to it while the other core section may be made of sheet material having only a lengthwise preferred direction of orientation. A transformer having such a composite core has smaller core losses and compensates for unmatched characteristics of semiconductor devices in circuits such as a two transformer inverter, Fig. 10 (not shown). It may also be used to prevent gradual saturation of the magnetic core structure in half-wave rectified circuits. Additional windings may be provided on the individual core sections so that the magnetic characteristics of each can be measured; the winding on the core section having a low coercive force can also be used as a constant voltage source provided that part of the core is saturated.

Abstract: 1362542 Caps for containers E H GREEN 7 Oct 1971 [6 Jan 1971] 46651/71 Heading B8T A reusable tamperproof resilient cap 12 for an aerosol container, has a cylindrical body 32 and an upper closed end 34, and is mounted in a well 20 by means of a flange 36 and a skirt 42 adapted to fit tightly within the interior of the well 20 so that the cap 12 may only be removed by means of a prying tool 48 placed within an opening 46, 50 formed in adjacent parts of the flange 36 and skirt 42 respectively. Cap 12 is secured to the wall of the well 20 by means of an outwardly projecting bead 44 formed on the exterior surface of skirt 42 so as to snap into a receiving groove on the interior of the wall. On insertion of the prying tool 48, to remove the cap the portion of the skirt 42 underlying the opening 46 is deflected inwardly toward the axis of cap 12 thus freeing the bead 44 from the groove.

Inventor: BARTHALON MAURICE
IPC: B60V3/04
Filed: 1967-10-13
Abstract: 1,198,268. Transporter systems; tracked hovercars. M. BARTHALON. 13 Oct., 1967 [14 Oct., 1966], No. 46780/67. Addition to 1,167,621. Headings B7K and B7L. The transporter system of the parent Specification 1,167,621 (comprising a powered car suspended from an overhead track beam by creating a sub-atmospheric pressure in lifting chambers formed between the car and the beam) is improved or modified as follows. A track switch, Fig. 5, is provided between tubular track portions 1a 1b 1c and comprises tubular track sections 201, 202 which are joined by members 203, 204 supported by rollers on tracks 211, 212 and which are movable by drive units. A stop on the member 204 may block the track 1b. Automatic braking of a car travelling along a track portion which is not connected by the switch, e.g. track portion 1c, is effected by uncovering apertures 231c in the beam (so that air leaks into the lifting chambers and the car engages the track) in response to the non-alignment of lugs 241, 242 on the section 202 and portion 1c. Alternatively, a car may be traversed between tracks on a single track section 201. In Fig. 7, the throw of the suspension chamber 254 is several times that of the lifting chamber 91, and the walls 282, 281 thereof are elastically deformable. Springs 259 and dampers 261 connect the slide block 86 to the car body 9. The track beam may comprise two coaxial tubes (Fig. 10, not shown), the inner tube conveying water, gas or oil, and the space between receiving electric or air lines; a conveyer may be disposed in the inner tube. In Fig. 11, transverse flexible skirts 33 define lifting chambers 15a to 15g divided centrally by a longitudinal throttling member. The skirts at the ends and centre of the car are closer together longitudinally than their transverse spacing, and the edges 270a are inclined. The extraction duet density is greater in the chambers 15a, 15b, 15c than in the other chambers, and the duct density increases away from the centre. The air extractors for the end and centre chambers increase their rate of flow as the chamber pressure falls, and each comprise a centrifugal compressor with a rotor having ribs inclined in the direction of rotation, while the extractors for the other chambers have a normal characteristic. In Fig. 16, the stabilizing chambers 281a, 281b are at superatmospheric pressure, the lifting chambers 59a, 59b at subatmospheric pressure, and zones 305a, 305b at atmospheric pressure. The projections 301a, 301b may be on the slide block 55, not on the beam 1.

[Also in Divisions G1 and G2] In photographic flash apparatus of the type in which an electronic flash tube is extinguished when a photo-electric integrator has received a predetermined amount of light reflected from the scene, the D.C. operating voltage for the photo-electric integrator is derived from the current in or light from the flash tube. When flash tube 2 fires, the peak voltage across resistor 3 is held on capacitor 5 by diode 4 and provides the D.C. supply to an integrator comprising a photoresistor 6, film speed setting resistor 7 and capacitor 8. When the voltage on capacitor 8 reaches a predetermined level, S.C.R. 11 fires to discharge capacitor 15 into the primary of transformer 16; the pulse thereby induced in the secondary fires a discharge tube 17 to short circuit and extinguish the flash tube 2. In a modification, capacitor 5 is charged by a photocell positioned to receive the light from flash tube 2.

Rotation is limited to 90 by a knighting pin 29. The valve is actuated by cable 27 and lever 23. It is stated that there may be more than two inlet-outlet connections, and that the sleeve may be replaced by a wall portion corresponding to the portion 47, resiliently mounted on the crank.
