Title: Magnetic field measuring apparatus
IPC: G01R33/028
Filed: 1973-04-19
Abstract: 1402513 Measuring magnetic fields: flaw detection FRIED KRUPP GmbH 19 April 1973 [22 April 1972] 19144/73 Heading G1N A circuit arrangement for measuring very weak alternating magnetic fields 21 includes a receiver coil 6 having an inductive reactance jwL and a natural ohmic resistance R1 and an electronic amplifier circuit 7 connected in series with the receiver coil 6, the input resistance of the amplifier circuit 7 being of the same value but of opposite sign as the resistance R1. As a result of this ideal shortcircuit operation of the coil takes place and the measurements are independent of the frequency of the alternating field. The amplifier circuit 7 is in the form of an operational amplifier 11 having a feedback resistance RG, regenerative feedback resistance RM and an input resistance RE. Resistances RG, RM, RE are so dimensioned that RE x RG/RM is equal to the natural ohmic resistance R1 of the coil 6 and it is shown that if this is the case the output 8 is independent of the frequency of the induced voltage in coil 6 due to changes in magnetic field 21. A further non- inverting operational amplifier may be connected with its positive input terminal connected to output 8 via a high pass capacitive coupling, Fig.3 (not shown). As a result the signal measured with respect to ground at the output of the further amplifier represents only field intensities originating from high frequency components of the field 21. The low frequency components signal may be obtained by measuring the output between 8 and the further amplifier output. Elimination of stray fields: If the matching conditions of the coil and amplifier circuit are not met to obtain stable operation a lower frequency limit of the circuit is obtained. An adjustable resistance may be connected in parallel with resistance RE to set the lower frequency limit. Alternatively a variable resistance may be connected in series with coil 6 in which case resistance RG is made variable. If the signals being measured have a frequency range within that of the variation in the earth's field the receiver coil is divided into two half coils arranged coaxially at a predetermined distance apart and connected in series opposition, Fig. 4 (not shown). Applications. The apparatus may be used to detect flaws in ferromagnetic objects carried past the pick-up coil 6 on a conveyer, Fig. 1 (not shown) the coil detecting magnetic fields due to cracks, interplanetary magnetic fields, the coil being carried in a satellite or the magnetic purity of objects.

Abstract: 1,049,243. Endless conveyers. BALL BROTHERS CO. Inc. May 12, 1964, No. 19622/64. Heading B8A. An apparatus for conveying glass bottles from a lehr conveyer 12, guiding them into single file past inspection and rejecting apparatus 157, 158, 159, 160, 161, 162 and conveying them away for packing comprises three parallel unscrambling endless belts 13, 14, 15 communicating the lehr conveyer 12 with a rotating disc 57 which together with a pair of guides 75, 76, transfers the bottles in single file on to an endless belt 121 via two parallel endless belts 64, 65 and a divergent extension of the guides 75, 76 guides a line of bottles on to each of two further variable speed endless belts 122, 123 and past the inspection apparatus, after which accepted bottles are all guided back into a single file on the downstream end of the conveyer belt 121. The endless belt 13 adjacent the end of the lehr conveyer 12 can move in either direction, the centre belt 14 moves towards the discs 57 and the belt 15 moves away from the disc 57 to effect an unscrambling action for the bottles which are then fed between the guides 75, 76 with the aid of vertically mounted guide rollers 74. Guides 78, 79 at the end of the belts 13, 15 remote from the disc 57 deflect bottles from the outer belts on to the centre belt 14 The guides 75, 76 are spaced above the belts 64, 65 so that broken and tipped bottles are removed from the system by the said belts. Bottles delivered on to the belt 121 pass on to a stationary horizontal plate over the belt 121 in the area where the guides 75, 76 start to diverge 144, 145 and then pass in spaced relation on to the two spaced belts 122, 123 whose speeds are varied relative to belt 121 to facilitate the spacing of the bottles the latter then pass the inspection apparatus 157 to 162 whereupon reject gates 164 to 169 are operated to reject faulty bottles either into bins 186 to 188 via guide rails 171-173 and shoots 178 to 180 from the belt 122, or on to a reject conveyer 185 via guide rails 174-176 and shoots 181 to 183 from the belt 123. Accepted bottles are directed from the downstream end of the belt 123, across the belt 121 and on to the belt 122, by a guide bar 190, whereupon these bottles join the accepted bottles on the belt 122 and are deflected therewith onto the downstream end of the conveyer belt 121. The operation of the inspecting apparatus is initiated by a bottle passing through the light beam of an adjustably positioned photo-electric device, or by mechanical means whereupon the bottle is pneumatically clamped while a plug gauge, as described in the present embodiment, is pneumatically lowered into the neck of the bottle. If the gauge does not pass into the neck, a full combination of switches are not operated by the gauge moving mechanism and the rejection gate is pneumatically switched into the conveyer path and later causes rejection of that bottle. In further embodiments all the bottles may be guided on to one of the belts 122 or 123 or they may all continue to pass along the central belt 121.

[Also in Division H2] Windings which extend as annular protrusions from a magnetic core, such as stator or rotor windings in a dynamo-electric machine, are encapsulated in an insulating medium by arranging annular U-section channel members over the protruding portions of the windings to serve as moulds during the encapsulating process, the annular members being formed by bending suitable lengths of U-section channel of non-magnetic metallic foil sideways into circular form, at least one side wall of the channel having corrugations to provide strength combined with flexibility. Fig. 3 shows a section through an arcuate length of corrugated channel 1 seen from above in Fig. 1. Such channel 1 bent to annular form is arranged over the end windings for the stator of an electric motor. The outer edges 5 of the channels are bent outwardly and secured by adhesive to the stator core 12 ; the inner edges 6 are also secured to the stator core by an adhesive. In order to prevent contact between the channel 1 and the end windings 17 an insulating lining is provided to the channel or the windings are wrapped in an insulating fabric 18 such as glass cloth or paper. Preferably, further foil 21, 22 is bonded to the outer and inner surfaces of the stator 56 and the stator is effectively totally enclosed. Leads are led out at 19 and a further aperture is provided at 20 through which the liquid encapsulating medium, such as a thermosetting or thermoplastic resin, preferably an epoxy resin, is introduced before curing or setting. A neoprene bore expander 23 is introduced down the centre of the stator to reinforce the inner surface of the channel 1 and the foil 22 during impregnation. The foils 1, 21, 22 may be removed after encapsulation or may be left to provide a " canned " stator. Alternatively, if the foil 21, 22 is not used during encapsulation it may be added later. Alternative forms of channel which are corrugated on inner or outer surfaces only may be used.

Abstract: 690,221. Delivering powder in measured quantities. ROSE BROS. (GAINSBOROUGH), Ltd. July 5, 1950 [July 28, 1949], No. 19824/49. Class 106 (v) [Also in Group XVII] In apparatus in which powder is fed from a hopper to a succession of measuring pockets in turn and the successive charges are discharged from the pockets into a succession of containers, each pocket is constituted by a tubular sleeve of flexible material, e.g. fabric or rubber, and means are provided for collapsing the sleeve at a position intermediate its length to allow it to hold a charge of powder, release of the collapsing means being effective to discharge the charge of powder into a container. As shown, powder 11 flows from a supply pipe 12 into a collecting chamber 13 from which it passes through apertures 14 in a rotatable wheel 16 into subsidiary hoppers constituted by flanged extensions 17 of the wheel and the upper portions of a series of flexible sleeves 18 attached thereto. The chamber 13 is arranged in an annular channel 26 in the wheel and forms with the base thereof an enclosed space through which the subsidiary hoppers pass in succession. The forward wall of the chamber acts as a scraper for the base of the channel, and auxiliary scrapers 25, Fig. 2 (not shown), are provided for sweeping any surplus powder back into the chamber 13. The wheel 16 is carried by a series of pillars 27 extending upwardly from a chain wheel 28 which drives a chain conveyer 24 for cartons 23 to be filled. An adjusting wheel 33 arranged below the wheel 16 is formed with bosses 34 slidable on the pillars and with a central hub 36 supported by a thrust bearing 37 carried by a sleeve 38 making threaded engagement with a rotatable adjusting shaft 41. The wheel 33 carries a series of pairs of gripping members 42 and 43, one pair for each subsidiary hopper, pivoted at 44 and 46 respectively in brackets 47 and 48 and operated by arms 49 formed with arcuate racks 51. The arm 49 operating the gripper 42 is part of a twoarmed lever 49, 52 coupled by a spring toggle member 53 to a two-armed lever 56 pivoted at 54 on the bracket 47, the lever 56 carrying rollers 57, 58 arranged to engage stationary cams on the main framework of the apparatus whereby the gripping members are opened and closed at intervals to release or collapse the sieeves.
