Abstract: 996,379. Gas fires; air heaters. OATLEY TECHNICAL DEVELOPMENT Ltd. Sept. 6, 1961 [Sept. 6, 1960], No. 30650/60. Headings F4S and F4W. An incandescent gas fire has radiants with a close back wall, the radiants heating a boiler having flow and return pipes, located directly behind the radiants such that the products of combustion of the fire do not contact the boiler surface, and the boiler being detachable from the fire for ease of fitting to the flow and return pipes. In the embodiments shown, the gas fire 8 consists of gas burners 37 and radiants 7. The back 33 of the radiants 7 rests on a flange 32 of the boiler 6 to form an air space 38. Above the radiants is a heat-exchange chamber 5 through which inclined shafts (not shown) pass. Air flows through the shafts by convection from an entry 9 to an exit 10 and hence through a vent 11 to the room space. The boiler 6 consists of two flat sheets 19, 20 flanged at their edges to overlap one with the other to enclose a water space 21. The sheets 19 and 20 have horizontal ribs 22 in order that water from inlet connection 23 should flow in a sinuous path to outlet connection 24 (Fig. 4, not shown). The flow and return pipes 17 and 16 have isolation cocks, which, when the boiler 6 is attached to the gas fire 8 in a fireplace opening 40, are accessible only when the apparatus is dismantled. The fireplace opening 40 is closed by plate 13 which is apertured to fit over flow and return pipes 17 and 16. The back 33 of radiants 7 is of substantially the same shape as the front face 19 of the boiler 6. The boiler is attached to the fire by means of lugs 27 and screws 28 accessible from the front of the fire after the removal of detachable plates 41 and 42. In a modification (Fig. 5, not shown), instead of detachable plates 41 and 42, side plates are provided on the gas fire.

Title: Magnetic separator
Inventor: PERRY ALFRED THOMAS
IPC: B03C1/03
Filed: 1963-08-06
Abstract: 1,094,646. Magnetic separators. J. & F. POOL Ltd. July 27, 1964 [Aug. 6, 1963], No. 31015/63. Heading B2J. A magnetic separator comprises a container 14 for feeding slurry containing magnetic and non-magnetic particles on to rotatable polepieces 18, 19 which carry the slurry past a magnetic field, means for washing the magnetic particles attracted to the pole-pieces during passage through the magnetic field and means for washing the magnetic particles off the pole-pieces when they have passed out of the magnetic field. As shown, the slurry is agitated by a motor-driven impeller 31 as it is fed via three circumferentially spaced apertures 35 and motor-driven rotary-vane feeders 35A into the space between two conical plates 18, 19 forming the pole-pieces. The pole-pieces are made of chromium-plated brass and are revolved on a track 21 to pass through three pairs of electromagnets 24A, 28 by a worm-shaft 15. Water from a tank 30 is sprayed through jets (36), Fig. 2 (not shown), between the plates 18, 19 from above in the region of the magnets so as to both assist the passage of non-magnetic particles into the sections (39) of a gully 38 and wash the adhering magnetic particles. Water is also sprayed through jets (37) between the plates at those parts moving out of the influence of the magnets so as to wash the magnetic particles into the sections (40) of the gully. During passage of slurry through the magnets, the polarity of the magnets is reversed so that the magnetic particles carried on the inside surfaces of the plates 18, 19 are turned over during this movement thereby freeing trapped non-magnetic particles. If desired, permanent magnets may be employed instead.

Title: Soundness investigation
IPC: E02D33/00
Filed: 1974-07-16
Abstract: 1521252 Investigating structures and materials R J SAVAGE 16 July 1975 [16 July 1974 28 Nov 1974 12 Dec 1974] 31500/74 51660/74 and 53803/74 Heading G1G The soundness or structural integrity of a structure is tested or monitored by transmitting vibrations through it, varying the vibration frequency, sensing the structure's vibration response at several locations of the structure, recording the vibration response frequency spectrum for each location, and either comparing the spectrum with reference data or detecting frequency shifts of the spectral peaks over a period of time. The invention is applicable to detecting fissures, aquifers or other underground anomalies e.g. below the foundations of a building or ahead of a tunnel face being driven; detecting structural changes in off-shore oil and gas platforms or in bridges, railway track, tunnel walls, or building components (beams &c); testing the strength of concrete; and to medical uses such as investigating the soundness of teeth or testing the repair of broken bones. For underground investigations a swept-frequency vibrator is coupled to the earth surface, Fig. 1 (not shown), to a vertical borehole wall, Fig. 4 (not shown), or to a tunnel face, Fig. 3A (not shown) and vibration sensors are located respectively at the earth surface, in further vertical boreholes, or in holes bored ahead of the tunnel face. Voids, &c, in the ground are detected by the resonances produced in the vibration response sensed and are localized by triangulation, using rotatable sensors. Each sensor comprises a triaxial accelerometer. Acoustic coupling of the vibrator to the ground is afforded by a saucer-shaped member held against the ground by vacuum. Fig. 5 shows a vibrator for generating shear waves in a borehole. It is anchored by a gas-filled device 26 and comprises an electrically insulated tube 20 filled with a gel in which are suspended magnetizable metallic particles 25. Application of an A.C. signal across end electrodes 23 is said to produce oscillation of the vibrator in the direction of the borehole axis. For monitoring the structural integrity of an off-shore platform at least one vibrator and several sensors are fixed above the waterline to various structural members and the vibration response is recorded digitally at intervals (of days or longer). Additionally, strain gauges are fixed to structural members below the waterline. Fig. 13 shows such a gauge, of the vibrating-wire type, in which the wire 45 is within a tube 44 fixed at least at its ends to a member. Electromagnets 46 vibrate the wire transversely in an upper harmonic mode and are used detect the vibration frequency.  Alternatively a longitudinal-wave mode gauge can be used, Fig. 14 (not shown), or the gauge may comprise a water-filled tube with means for timing the two-way propagation of a shock-wave along the water column, Fig. 15 (not shown).
