Title: Improvements relating to magnetic crack detection
Inventor: WALLEY JAMES WILLIAM
IPC: G01N27/84
Filed: 1953-12-21
Abstract: 791,650. Magnetic tests. METROPOLITANVICKERS ELECTRICAL CO., Ltd. Dec. 14, 1954 [Dec. 21, 1953], No. 35524/53. Class 37. For dipping articles to be tested in a bath of magnetic fluid a pair of cranks are provided, so coupled as to rotate together with the article under test clamped between their ends to immerse the article in the bath during part of the revolution. As shown, the article to be tested is clamped between faces 10, 11 of cranks 8, 9 which are attached to shafts 1, 2 journalled in bearings 2, 3. At the lower part of their throw the cranks dip the article in bath 23 containing magnetic fluid. A coupling shaft 14 and chain drives 12, 13 are provided so that the cranks rotate together. Shafts 1, 2 each consist of an inner part 16, 20 and an outer part 15, 19. In the case of shaft 1 the inner part is axially movable under the action of a spring 17 which thus clamps the article between the faces. Relative angular rotation of the two parts is prevented by handle 18 which is pivoted at 19 in the outer part and passes through the inner. This handle serves to compress spring 17 to enable the article under test to be withdrawn. The inner part of shaft 6 is adjustable by means of a set screw in the outer part engaging a slot 22 in the inner. Coils 24 provide an axial magnetizing field which passes through the cranks, the article, frame 5, 6 and shaft 28, while a circumferential field is derived by applying A.C. to terminals 25, 26. Cams rotating with the crank shafts may serve to switch on and off the magnetizing currents or, if desired, to insert permanent magnets in the magnetic circuit and to short-circuit them. In Fig. 3 the crank positions are represented by the radii and the article position by the ends of these radii. At position I the article is inserted, at II the axial field is applied, at III the axial field is removed, at IV the A.C. field is applied, at V the A.C. field is removed, and at VI observation of the article leaving the bath commences and continues to I. A mirror 38 is provided to facilitate the observation. In the embodiment of Fig. 2 (not shown) the two cranks are coupled by a central non- magnetic shaft splined in the left-hand crankshaft and projecting therefrom to engage the face of the right-hand crankshaft.

Abstract: 762,748. Railway signalling apparatus. STANDARD TELEPHONES & CABLES, Ltd. Dec. 9, 1954 [Dec. 12, 1953], No. 35633/54. Class 105. Railway signalling apparatus includes a supervisory device and switching means responsive to an initial operation of said device to release and reoperate the said device before the signal can be operated. A storage relay SB operated on the initial operation of the supervisory relay SA releases at back contact sb<3> the relay P and at front contact sb<1> prepares the pick-up circuit of a latch relay W which is picked up at back contact sa<1> when relay SA releases, the relay W on operation closing at front contact w<3> an alternative pick-up circuit for the relay SA and at front contact w<4>, preparing a circuit for lighting the signal lamp L, or may be for operating a locking equipment which circuit is completed at front contact sa2 on the second operation of the supervisory relay SA. Preparatory to a train movement from section a, Fig. 1, to track section 1 contacts pr<2>-pr<4> are closed when the track points in the track sections 2-5 respectively are in the correct position for the route. Track relay contacts ta and t<1>-t<4> are closed when the respective sections are unoccupied. When the route is set and contacts pr and t are all closed, the contacts f<1>, f<2> are closed and f<3> opened as by a manual operation or by an automatic operation, e.g. by a relay in a route setting or route selecting apparatus and relays U, P are picked up, followed by the relay SA on closure of contact u<1> and relay SB over front contact sa<1>. At contact sb<3> the pick-up circuit of relays U and P is opened, the former relay releasing immediately and at contact u<1>, releasing relay SA, relay SB being then held by discharge from the condenser C. While the slow release relay P is still up, latch relay W is picked up over back contact sa<1> and front contacts pl and sbl and this pick-up circuit is thereupon opened at contact w<1> and at front contact w<5>. The release circuit of the latched up relay W is prepared for completion on restoration of the contact f<3>. At front contact w<3> the second pick-up circuit for relay SA is completed over contact sb<5> and at front contact w<2> a holding circuit over front contact u<1> and back contact p<2> and front contact sb<2> is completed for relay SB. At front contact sa<2> the circuit for the signal lamp L of signal A, Fig. 1, formerly prepared by contacts w<4> and sb<4> is completed. As the train passes along the route the "t" contacts open in succession and release relay SB followed by relay SA and extinguishing the lamp L. When the contacts f<1>, j<2> and f<3> are restored on the passage of the train, the release circuit of latched-up relay W is closed at f<3>. The prevention of false operation of the signal under faulty conditions is also described.

[Classes 74 (i) and 74 (ii)] Previously formed strips of elastic or other braided fabric are united to a knitted fabric in the process of knitting a stocking or other article. Fig. 1 shows a knitted stocking in which braid is incorporated as a top edging 5 as an intermediate depending circular band 10 and as a sectional insert 15. The inserts may be of openwork, preferably formed with selvedges. The band 10 or a number of them may be transferred to the needles before starting to knit, to be stored below the knocking-over bits 29 until the part of the article is reached at which it is desired to incorporate a strip or strips of braid. Each band is then raised in turn to permit the next formed course of knitted loops to interengage with the previously-formed course, the reengaged first formed course and the braid loops. To provide a braid edging 5 for the top of the article, the braid loops are transferred to empty needles as a first step' before knitting the first course of the article. This edging may also be added at the fold of the usual welt by pressing the transferred braid loops on the needles before starting knitting and raising them above the knock-over bits when forming the course that will lie at the fold of the welt. When a sectional insert 15 is made, the selvedge 20 is subsequently seamed or otherwise united to the side edges of the braid.

Filed: 1963-09-19
Abstract: 1,064,251. Semi-conductor devices. WESTERN ELECTRIC CO. Inc. Sept. 19, 1963 [Oct. 4, 1962], No. 36878/63. Heading HIK. [Also in Division G1] A stress measuring device employs two parallel connected tunnel diodes 41, 45, Fig. 2, one being formed on a P-type wafer 42 and the other on an N- type wafer 46, the parallel arrangement being biased to operate at the maximum current of the combined current/voltage characteristic without entering the negative resistance region. The value of the current maximum varies with stress applied to the junction while the voltage Vm at which this maximum occurs is substantially constant since the variations under stress of Vm for the individual diodes are equal and opposite (92, 94, Fig. 6, not shown) and consequently cancel. Also, the actual value of the current maximum for each diode varies with temperature in opposite directions and hence the combination is independent of temperature (Fig. 5, not shown). The stress in a member 30 is transmitted to the diodes 41, 45 via a rigid shelf 48 and a resilient member 32 carrying cone-shaped terminals 36, 38, these cones acting to magnify any stress, particularly alternating stress in member 30 at diodes 41, 45. The diodes may be mounted alternatively on a flat spring (54, Fig. 3, not shown) which bends according to the strain in member 30. The diode 41 may be made by fusing a silver ball 40 containing 2% tellurium to a gallium antimonide wafer 42 containing a zinc impurity, and the diode 45 by fusing a cadmium ball 44 containing 5% gold to a gallium antimonide wafer 46 containing tellurium impurity, the fusing process takes only a fraction of a second. Circuits are described (Figs. 1, 4, not shown) which measure the current/voltage characteristic of a single diode and a pair of diodes respectively.
