Abstract: 851,104. Oil wells. CAMCO Inc. July 1, 1959 [Aug. 13, 1958], No. 22567/59. Class 85. A control device is positioned in a tubing string by a retrievable hanger which is landed and latched in a nipple 1 having a landing shoulder 2 and an annular notch 4 for receiving latching dogs 14. The hanger comprises telescoping members 5, 6, the latter having windows for the dogs 14 and the former having a relieved surface 15 which allows the dogs to retract when the device is being run in. The member 6 is connected to a member 9 which is clutched temporarily to the member 5 by dogs 4 engaging a groove therein, the dogs being kept in the groove by a ring 25 connected to the member 9 by tangential shear pins 28. The device is run in by a hollow cupped member 31 suspended from a jar head 32 from a wire line 33 and attached to the member 9 by shear pins 34. When the ring 25 lands on the shoulder 2, the dogs 15 are aligned with the notch 4. A downward jar shears the pins 28 and allows the member 9 to descend until the ring 25 abuts against the shoulder 27, the dogs 24 being thus released from the member 5, but prevented from complete dislodgment by the skirt on the ring 25. The sleeves 5 is now free to descend still further, to cam the dogs 14 positively into the notch 4, and is held in this position by aluminium or like soft metal ratchettoothed arcuate members 11 which are pressed inwardly by coil spring 12 to engage a ratchettoothed formation on the member 5. An upward jar on the line 33 now shears the pins 34 and the running in gear is removed. When the device is to be retrieved, a fishing tool grasps the neck 19 and collar 20, an upward jar on the member 5 strips the ratchet teeth on the members 11, the dogs 14 are aligned with the relief 15 and the device is free to leave the well.

Abstract: 1,141,884. Toothed gearing. IMPERIAL METAL INDUSTRIES (KYNOCH) Ltd. 27 April, 1967 [23 May, 1966], No. 22873/66. Heading F2Q. In a gear train comprising driving and driven gear-wheel units 4, 5 (Fig. 2), the distance between their axes of rotation being variable, connected by an idler gear unit 12, each unit comprising a gear-wheel 8, 10, 13, and at least one coaxial cylindrical spacer 9,11, 14, the spacer 14 of the idler unit being in rolling contact with those of the driving and driven units when the gear teeth are in correct mesh, the relative disposition of the units is such that the resultant of the forces applied to the idler gear teeth acts in a line passing between the axes of rotation of units 4, 5 to hold the idler teeth constantly in correct mesh with those of the driving and driven gears. This is so when the angle between a line through the axes of rotation of the units 4, 12 and a line through the axes of rotation of the units 5, 12 is greater than twice the pressure angle of the meshing gear teeth. The spacers have diameters equal to the pitch circle diameters of their respective gear-wheels and are integral therewith. To retain the idler unit when stationary, or on overrun, a spring 15 may be used, or a slipper block (22) (Fig. 6, not shown), or a fixed peg (19) within an annular idler unit (18) (Fig. 5, not shown). If the axes of the units 4, 5 lie substantially in the same horizontal plane and the idler is above them, gravity suffices. In Fig. 7, a belt 29 round pulleys 30, 31 forming axial extensions of the driving and driven units 25, 26 prevents relative rotation of the latter when they are unloaded, to prevent the idler unit 24 from falling out of mesh. In Fig. 8 (not shown) an idler (12) is carried on an arm (34) pivoted on the shaft (6) of the driving unit (4) for use in opposite directions of rotation, a friction coupling between the arm (34) and the shaft (6) moving the idler from one drive position to the other when the drive is reversed. In Fig. 11 the pitch circles of the driving and driven units 35, 40 overlap, the unit 35 having two gear-wheels 36 spaced apart and the spacers 43 of the unit 40 being axially spaced from the gear-wheel 41. Gears 36, 41 mesh a wide idler gear (46) (Fig. 10, not shown). In Fig. 13, a driving unit 52 lies within an internally toothed annular driven unit 49 and is connected thereto by an idler unit 53. The gears may be of metal, rubber, or plastics

Title: Electronic wheel detecting devices
IPC: B61L1/16
Filed: 1975-05-23
Abstract: 1492656 Wheel detector AGENCE NATIONALE DE VALORISATION DE LA RECHERCHE 23 May 1975 22936/75 Heading B7M  A wheel or vehicle detector for a railway system comprises a receiver coil disposed on one side of a track rail and coupled to a pulse receiver and a pulse transmitter disposed on the other side of the rail which includes an arrangement for discharging a capacitor through an output circuit which can be one of two kinds, either the circuit is a normal radiating coil in which case a wheel is detected when it blocks normal continuous transmission between radiating and receiving coils or the circuit can be two coils connected in series opposition whereby the receiving coil only receives radiated pulse signals when wheel presence distorts the opposing radiated fields. The transmitter comprises a relaxation oscillator T1 which controls triggering of a thyristor Th1. The thyristor discharges capacitor C2 through the output circuit comprising either radiating coil b1 or coils Le1 and Le2 coupled in series opposition. The capacitor C2 is charged via coil L1 which resonates with capacitor C2 at the relaxation oscillator frequency. Where the transmitter continuously radiates the pulse signal the receiver, Fig. 2, includes amplifier A1 coupled to monostable circuit M1 which supplies an output via amplifier A2 and rectifier D2 to charge capacitor C2 and pick up relay R1. The output from amplifier A2 is also rectified D3 to charge capacitor CM which provides power supply for the monostable circuit when relay R1 is picked up. When a wheel interrupts transmission for more than 3 pulse cycles, capacitor C2 discharges releasing relay R1 so that circuit 2 opens to indicate vehicle presence. Unit 5 delays resetting the arrangement by supply of power from source 4 to the monostable circuit for a fixed period of time. Where transmission only occurs when a wheel is present between transmitter and receiver, the output of receiver coil B2, Fig. 3, is amplified A3 and triggers monostable circuit M2 which supplies an output to charge capacitor C4 and this provides power to an oscillator 01 which in turn supplies an output via rectifier D5 and capacitor C5 to operate relay R2 controlling indicating circuit 6. At least 3 pulses are required to charge C4 to a level which allows the oscillator to operate. The Specification also describes combinations of both arrangements, Figs. 4-6, (not shown) which provide detectors operable only in one direction of travel.

[Class 87 (ii)] In moulding disc records, particularly those of small diameter and thickness, a circular groove is pressed on one or both sides of a disc of material so that a ring remains on the disc outside the groove which has a diameter equal to that of the desired record, the ring being subsequently broken off. The mould parts a, b, which may be of a size suitable for records of 25 cms. diameter, are provided with matrices c, d secured by clamping rings e, f. One or both matrices are formed with circular projections g, h such that grooves of the desired diameter, e.g. 10 cms, are formed. The height of the one or the sum of the two projections is less than the thickness, e.g. 0À2-2À0 mm., of the disc to be moulded, so that the outer ring is still attached to the record when it is removed from the mould. The ring may be broken off by placing the disc on a metal die of a diameter somewhat less than that of the record and manually applying pressure to the ring.
