Title: Inductive proximity transducers
Inventor: BOWMAN ROBERT MILLAR
IPC: G01B7/14
Filed: 1965-08-12
Abstract: 1,148,064. Proximity detectors. ENGLISH ELECTRIC CO. Ltd. Aug. 12, 1966 [Aug. 12, 1965j, No.34529/65. Heading G1N. The displacement of one magnetic body relative to another body is measured by embedding in the second body a measuring coil whose inductance changes with changes in the relative displacement, temperature compensation being provided by a non-inductive coil coaxial with the measuring coil which is connected into the measuring circuit so as to compensate for the effects of changes in resistance of the measuring coil due to changes in temperature. In the embodiment, for measuring the displacement of a steel shaft 10, Fig. 1, in its bearing 11, in order to measure the thickness of an oil film in the interspace 12, a measuring coil 15, e. g. of enamelled copper wire, and a coaxial temperature compensating coil 16, having approximately the same resistance and of the same material as the coil 15, are mounted in the bearing 11 in a ferrite body 14. A second similar displacement transducer, comprising measuring coils (15A), (16A), Fig.3 (not shown), may be mounted diametrically opposite the first transducer in the bearing 11, the two being connected into the two arms of an A. C. bridge network, with the temperature compensating coil of one transducer connected in series with the measuring coil of the other transducer, the other two arms of the bridge being provided by resistors (21). In a modification, one of the measuring coils may be placed in a position where there is no variation in inductance. Alternatively the two transducers may be displacedby 90 degrees, Fig. 4 (not shown), the coils of each transducer being connected in separate bridges, e.g. of the kind shown in Fig. 3 (not shown). The measuring and non-inductive coils may be provided by four single windings of insulated wire, twisted together to produce four identical coils, two being connected together so that the inductive effects are additive, which coils thus constitute the measuring coil, and the other two coils being connected together so that the inductive effects are subtractive to thereby constitute the temperature compensating coil. The invention may also be utilized to measure shaft vibration or fluid film thickness in seals.

Abstract: 196,651. Marks, E. C. R., (Peerless Machinery Co.). Dec. 22, 1921. Folding edges of sheet material.-In a machine for folding the edges of leather, cloth, &c. (1) the material is fed over a work-support which is curved transversely to the line of feed, the folded edge being pressed down by a device having a pressing-surface parallel to that of the work-support, and (2) a slitting-knife arranged at an angle to the line of feed is provided for slitting the material during folding on inside curves, so that the slits are formed at right-angles to the edge of the material. (1) The machine comprises a frame 10, Fig. 1, having lower and. upper arms 11, 12, the lower arm carrying a convexlycurved work-support 25, Figs. 4 and 8, adjacent to which are a gauge 30 for guiding the work, and a fixed plough 31 for turning over the edge. The material is fed through the machine by a feedbar 32, Fig. 3, and a feed-roll 33, the feed-bar being reciprocated horizontally and also having a rising and falling movement.. A pivoted presserfoot 34 holds the work in position between the feed movements. The feed-bar slides vertically in a housing 67, which is oscillated by a rock-shaft 60, so as to give the horizontal movement to the feed-bar, the extent of movement being adjustable by means of a crank of variable effective length. A fold-presser in the form of a reciprocating hammer 35, Fig. 8, presses the. turned-over edge on to the body of the material. The hammer is preferably reciprocated in a straight line by a rod 160 from a rock-shaft 165 acting through a spring. The hammer can be adjusted in position by rotation of the rod 160 so as to facilitate the folding where outside or convex curves occur in the material. (2) The slitting-knife 37, Fig. 10, is carried by a bar 213 reciprocating vertically in a guide 217, and co-operates with a slotted knifeblock 36, Fig. 4. The knife-bar 213 is connected by links 232, 234 to an actuating-crank 225, and means is provided for moving the pivot 233, which connects the links, into coincidence with the axis of the crank, in order to throw the knife out of action.

Abstract: 1,158,634. Turbines; gas turbine plant. CATERPILLAR TRACTOR CO. Aug. 2, 1966 [Sept. 13, 1965], No. 34566/66. Headings F1G and F1T. The inlet nozzle vanes 12 of a two-stage gas turbine forming part of a gas turbine engine are attached to an outer ring 13 and an inner ring 14, the latter being integral with a thin-walled annular member 41 secured to the engine frame 23 by bolts 43 which also serve to hold an insulation ring 42 which shields a shaft bearing 24 from high temperatures. The flexibility of the member 41 accommodates relative thermal expansion of the nozzle parts. Further protection for the bearing 24 is provided by an insulation jacket 33. Cooling air passes through a passage 52 between the insulation jacket 33 and the inner wall 17 of the turbine inlet scroll and thence via orifices 53 and along the outer surface of member 41 to the inner ends of the nozzle vanes 12. The cooling air also passes via orifices 54 and along the inner surface of member 41 to the inner ends of the blades of turbine wheel 18. A further stream of cooling air passes through a passage 46 between the insulation jacket 33 and the engine frame 23 and thence through passages 44 in the hollow bolts 43 to cool the turbine wheel 18. Lubricant passes to the bearing 24 via a passage 48 and a restriction 49. In a modification, Fig. 5 (not shown), the cooling jacket (33) is supported by the wall (17) of the inlet scroll, the passage 52 and the orifices 54 being omitted; the cooling air passing through the orifices (53) comes in this case from the passage (46). In a further modification, Fig. 6 (not shown), the insulation jacket (33) is moulded directly on to the engine frame (23), and the passage 46 is in this case omitted. In other embodiments, Figs. 1 and 2 (not shown), the member 41 is omitted, and the ring (14) is integral with an inwardly extending flexible disc (14a) bolted to the engine frame (23). A massive ring (32), Fig. 1, encircles the second stage turbine wheel (21) to provide protection against failure of the wheel.

Abstract: 1513443 Battery charging systems SAFTSOC DES ACCUMULATEURS FIXES ET DE TRACTION 22 Aug 1975 [23 Aug 1974] 34916/75 Heading H2H A circuit arrangement for charging a sealed battery comprises means for reducing the constant charging current when the battery terminal voltage reaches a predetermined value and for simultaneously energising a device for heating the battery. A battery 11 is charged from a D.C. source 1 by way of a constant current device which includes a transistor 12, resistor 14 and an operational amplifier 15. When the terminal voltage of the battery 11 reaches a predetermined value the input signal to a second operational amplifier 21 becomes such that a transistor 19 becomes conductive whereupon part of the charging current is shunted from the battery by a circuit comprising the transistor 19 and a resistor 20. The potential difference appearing across the resistor 20 is applied to the input terminals of another operational amplifier 27 by way of potential dividers 30, 31, 32, 33 and 28, 29. The output of the amplifier 27 renders a transistor 34 conductive thereby to energise a heating resistor 40 which heats the battery. A circuit which includes resistors 30, 37, 38 and a diode 39 is provided to ensure that the value of the current flowing through the resistor 20 for the transistor 34 to return to its non-conductive state is lower than the value of the current through the resistor 20 at which the transistor 34 becomes conductive. The shunt circuit 19, 20 and the heating resistor 40 remain inoperative if, during charging, the battery temperature exceeds 0C.
