IPC: G01D5/22
Filed: 1966-11-16
Abstract: 1,207,955. Transformers. HONEYWELL Ltd. 6 Oct., 1967 [16 Nov., 1966], No. 51324/66. Heading H1T. [Also in Division G1] Apparatus for recording and/or indicating the value of an electrical input signal includes a transformer unit comprisesing a transformer having inductively coupled windings, the turns of one of which are constituted by part of a flexible electrically conductive element, and means for winding and unwinding turns of said one winding. As shown, a fine wire conductor 13 is wound on a rotatable member 14 to produce two groups 15, 12 of turns the group 12 being wound in proximity to and closely coupled with the primary winding 10 of the transformer. Ends 18, 19 of the conductor 13 are fixed to a rotatable wheel 16 which may be non-circular such that rotation of the wheel in a given direction causes turns of one group to unwind while extra turns wind on to the other group. A tensioning pulley 20 and springs 31, 32 in the terminal leads 25, 26 take up any slack in the conductor. An alternative arrangement for winding and unwinding turns on drum 14 comprises two co-planar mounted pulleys (52, 53) (Fig. 4, not shown) which can move along a line joining their centres. As an alternative to the drum-winding arrangement shown, the primary is wound on the central post (34) (Fig. 3, not shown) of a ferrite core (33), the closely linked part of the secondary winding being located on a former (37) and disposed in an annular space between the central post and an outer annular part (35) of the core with the other part of the secondary well spaced from the primary. The other part of the secondary may be on the other end of the former (37) or on a separate former provided with a gear-wheel in mesh with a gear-wheel on the first former (37) for co-operative rotation and winding and unwinding of turns. In a modification (Fig. 5, not shown), two secondaries connected in series are each associated with a primary winding, the primaries being wound in opposite senses. The apparatus for recording and/or indicating the value of an input signal does this by comparison of the input signal with a standard signal derived from the transformer, which acts as a feed-back element from a two-phase induction motor (Figs. 1 and 6, not shown). A screen of copper, silver or aluminium may be disposed between the primary winding(s) and associated secondary winding(s). The fine wire conductor can be replaced by an insulating tape carrying several parallel strands appropriately connected, or alternatively, the flexible conductor may comprise a flexible tube filled with mercury.

Filed: 1972-11-21
Abstract: 1374020 Separating fibrous material from ore ALLIS-CHALMERS CORP 21 Nov 1972 [23 Nov 1971] 53698/72 Heading B2H A method of processing a mineral ore containing a desired mineral, e.g. nickel sulphide, and an undesirable fibrous material, e.g. asbestos, both associated with a gangue material, e.g. serpentine, comprises: (a) initially treating the ore to reduce it to a size suitable to form the input feed of a first grinding stage; (ib) subjecting the treated mineral ore at the first grinding stage to a relatively coarse grind sufficient to obtain liberation of substantially all of the undesirable fibrous material from the ore; (c) subjecting the discharge from the first grinding stage to a screening action to separate the liberated fibrous material from the defibred ore; and (d) subjecting the defibrated and separated ore at a second grinding stage to a grind sufficient to liberate a required amount of the desired mineral from the remainder of the defibred ore. As shown, the mineral ore is first crushed in a crusher 10 and fed to a first stage grinding, e.g. rod, mill 12, to which water is preferably added, so as to liberate the fibrous material from the ore. The fibre-laden, slurry discharged from the mill 12 passes through a screening device 14, which may be a stationary sieve bend or a vibrating screen, whereby the liberated coarse fibres are retained on the screen and the defibred slurry passes through. A dewatering device 17 may be provided to feed a fairly thick slurry to a second stage grinding, e.g. ball mill 16 to which water from a separate source may be added in controlled amounts to provide a proper solids-liquid ratio and in which the desired mineral is liberated from the ore. The ground material discharged from the mill 16 may then pass along an open circuit path 22 to further processing. Alternatively, the ground material may pass along a closed circuit path 23 to a classifier 18 which separates it into oversized product which is recycled along path 24 back into the feed end of the grinding mill 16 and undersized product which passes along path 20 to further processing. In a modification, Fig. 2 (not shown), the defibred slurry discharged from the screening device (14') passes through a classifier (18') which separates it into undersized product, which passes to further processing, and oversized product which passes through the second stage grinding mill (16') the output product of which is recycled back through the classifier. More than one grinding stage may be used downstream of the screening device.

Filed: 1974-12-18
Abstract: 1482789 Infra-red imaging system TEXAS INSTRUMENTS Inc 18 Dec 1974 [4 Jan 1974] 54737/74 Heading H4F An infra-red image scanning and display system comprises a linear array of infra-red detectors which are effectively scanned across a scene (e.g. by an oscillating mirror), each detector being coupled to a pair of charge coupled or bucket brigade type storage devices. In operation the line scan video signals from each detector are alternately stored in one of the two storage devices associated therewith while at the same time the previously stored line scan video signals from all the detectors are sequentially read-out of the other of the two storage devices at a much faster clocking rate than the storing clocking rate to thereby convert the simultaneous line scan outputs from the linear array of detectors into a television raster scan type video signal suitable for display on a monitor. The read-out of the clocked signal samples from the storage devices takes place during the forward scan movement of the oscillating mirror and during its flyback (non-pickup) scan movement. An interlaced television video signal may be produced by halving the number of detectors and tilting the mirror during alternate scans. In the embodiment described 900 video signal samples from each line scan video signal are stored in a two dimensional four-phase CCD array, there being 241 detectors in the linear array i.e. 482 CCD arrays are used.

Abstract: 1,269,283. Handles for percussive tools. VAUGHAN & BUSHNELL MFG. CO. 18 Nov., 1969 [21 April, 1969], No. 56449/69. Headings B4K and B5A. A moulded handle for a striking tool of a hammer head, is formed of a polymerized thermosetting resinous binder reinforced by fibre glass filaments and comprises a tubular section and a solid section adapted to receive a striking tool, the filaments extend longitudinally of the handle and are continuous throughout the length of the handle. The filaments in the tubular section are under longitudinal tensions and are therefore linearly straight, and the solid section of the handle has a wedge-receiving slot 20. An elastomeric handle grip 16 may be fitted over the tubular section. Method of moulding the handle.-A continuous length of fibre glass roving 30, Fig. 1, is pulled through binder-forming liquid resinous material in a tank 32, the roving is grouped into bundle form by an annular gathering die 44 and then cut into predetermined lengths by a cutter element 62. Movement of the roving is accomplished by means of a rack 50. A mould blank cut from the roving is placed between mould blocks 102, 106, Fig. 4, which are then closed. Each mould blank constitutes two handles connected end to end. During curing of the liquid binder a divider element 138 is inserted into the mould to produce a relief area 148, see Fig. 12. The tubular sections are produced by inserting mandrels 150 into the mould. When these are inserted the binder is uncured and the mandrels force the filaments outwardly and compress them and at the same time exert a high compression on the filaments and binder material near the central region of the mould cavity. As the filaments are forced radially outward the binder material is caused to flow outwardly thus causing tensioning of the filaments. Some of the binder is extruded from the end openings in the mould. The blocks 102, 106 have electrical resistance elements 131 therein to maintain them at the required curing temperature.
