Title: Improvements in or relating to magnetic speed indicators
IPC: G01P3/495
Filed: 1930-12-22
Abstract: 369,997. Magnetic speed indicators. ETABLISSEMENTS E. JAEGER, 2, Rue Baudin, Levallois - Perret, Seine, France. Dec. 22, 1930, No. 38580. Convention date, Jan. 7. [Class 106 (iii).] An eddy current speedometer comprises a rotating shaft 6 carrying the 4-pole magnet 1, fixed iron member 2, and drag member 3 rotated to a position of equilibrium against the action of the spring 34 for each speed of rotation and bearing on its surface graduations 37 read against a fixed index 18 through a glass plate 58 the plane of which is inclined to the reading plane of the member 3 to aid visibility when the instrument is read from above. The above arrangement provides the further advantage of having an inclined driving shaft. The worm 5 actuates a totalizing system 49 through the eccentric pin 40 on the axle 39 engaging in a hole 43 in a pawl 44 actuating the ratchet wheel 48. The apparatus is mounted within a casing 56 which has a covering member 59 having an aperture 60 to allow reading of the totalizer 49 and having a pressed or flanged part 61 which terminates in an aperture 62 to allow reading of the index 18 on the dial 37 of the drag member 3. The fixed iron member 2 is cut away at 63 to facilitate visibility. The lamp 66 emits rays which strike substantially perpendicularly on the reading plane of the member 3 to further improve conditions of visibility. The shaft 6 is provided with a recess 13 of polygonal cross section in which extends the head 14 of a rod 15. The rod 15 has a groove 16 in which extends a ring 17 provided with a radial notch to prevent translational movement of the rod 15 but allowing its free rotation. The ring 17 bears against the plane end 19 of a boss 20 which is screw threaded at 21 to receive a clamping nut 22 which confines the ring 17 between the boss 20 and the flange 23 of a socket 24, the end 25 of which fits into the flexible sheath 26 of a flexible shaft 27. The rod 15 is recessed at 28 to receive the end of the flexible shaft 27 on which it is forcibly mounted. The socket 24 constitutes a bearing for the rod 15 which is of great length. A socket 29 is located between the socket 24 and the end of the sheath 26 on which it is beaded, to ensure the rigid assembly of the sheath 26, of this socket 29 and of the bearing-socket 24.

Title: Drive assemblies
IPC: F16D43/284
Filed: 1965-09-10
Abstract: 1,046,605. Friction clutches. GENERAL MOTORS CORPORATION. Sept.10, 1965 [Oct. 5, 1964], No. 38696/65. Headings F2C and F2L. An hydraulically engaged friction clutch is lightly engaged by centrifugal fluid pressure derived from a chamber rotating with a driving clutch member and supplied to a clutch engaging servomotor rotatable with a driven clutch member, the pressure developed in the servomotor on rotation of the driven member providing full engagement. Friction plates 106 are alternately splined to a driving sleeve 40, which is splined to an input shaft 28, and to a driven member 42 fast with an output sleeve shaft. Servomotor chambers 84, 96 are provided in the driven member and receive an annular piston assembly having apply and retraction heads 82, 90 and biased to a retracted position by a Belleville spring 98. Fluid is supplied through an annular nozzle 124 to a chamber 126 provided between the input shaft 28 and driving sleeve 40 whence the centrifugally induced pressure is supplied through passages 130, 134 to the apply chamber 84 and through passages 135, 137 to the control chamber 96 whence the liquid passes to a sump through bleed passages 132. Initially liquid is supplied to the annular nozzle 124 at a high flow rate by a pump 114 driven by an electric motor 112 (Fig. 1, not shown). The liquid is supplied to the control chamber 96 at a rate faster than that at which it bleeds through the passages 132, so that pressure is developed in both chambers 84, 96. As the input shaft accelerates the pressure acting on the differential piston heads 82, 90 overcomes the pressure of spring 98 and the clutch is partially engaged. As the driven member begins to rotate centrifugal pressure is thereby developed in the chambers 84, 96 to give full engagement. The greater radius of chamber 84 results in a greater average pressure developed therein to provide a net force on the piston assembly which increases at a faster rate than the speed of the output member 42 until full engagement is obtained. The input shaft may be driven by a gas turbine 12, and the output sleeve shaft 44 be geared to a gas compressor 14. The output shaft 44 also drives a low delivery pump 150. At clutch lock-up the pump motor 112 is shut down to permit pump 150 to deliver to the chamber 120. The low flow rate provides oil for lubrication and cooling of the clutch plates, through passages 127, and maintains the apply chamber 84 full, but no oil is available for chamber 96 which empties through the bleed ports 132.

The propelling speed-change shaft 15 is coupled to a shaft 50 either directly or through a friction planetary reduction gear 40 (Fig. 7) whose sun gear 51 is driven by shaft 15 and whose planet carrier 49 is clutchable to shaft 50 by a sleeve 55, which sleeve can also directly connect shafts 15 and 50. A differential 62 for the rear wheels of the tractor is driven through a two forward speed and reverse gear-box whose output shaft 58 drives the differential through gears 63, 60. The front wheels of the tractor may also be driven from shaft 58 through gears 73, 80 and 78 and a shaft 82, the gear 78 being axially movable to connect or disconnect the drive. The clutches for engaging the gears on shaft 15 are shown in Figs. 3 and 4 (those for shafts 16 and 58 being identical) and comprise pins 36 spring-biased, by springs 35, out of engagement with recesses 39 of the gears and moved by a land 29 of an axially movable selector rod 27 (this being the selector for shaft 15) to engage a gear. The rod 27 acts on pins 36 through balls 37 and the recesses 39 are shaped to reduce shocks on engagement, which shocks are also absorbed by resilient coupling 11 (Fig. 2). The friction planetary gear 40, shown in Fig. 7 has a metal sun gear 41, a fixed metal ring gear 42 and planet gears 43 comprising inner and outer metal sleeves 44, 45 with resilient material (e.g. rubber) 46 between them. The planetary gear 40 slips on exess torque being transmitted.

Filed: 1972-07-21
Abstract: 1361794 Detection of moving bodies COAL INDUSTRY (PATENTS) Ltd 21 July 1972 [20 Aug 1971] 39201/71 Heading G4H Apparatus for detecting slipping of a lift cage cable 3 relative to a drive drum assembly 47 to which it is drivably attached solely through frictional contact comprises an inductance coil 10 located around the lift shaft 2, means 12 for detecting any change in inductance in 10 due to passage of the lift cage 1 and for producing a singal indicative thereof, indicator mechanism 25-29 for producing a second signal indicating the apparent position of the cage 1 when it is apparently adjacent to the coil 10, and a logic unit 23 which compares the signals to actuate an audible alarm 30 and stop the apparatus in the event of undesirable slip. Coil 10 is connected to an oscillator 13, Fig. 2 (not shown), in detector 12; this and another oscillator (16) produce a nominally constant beat frequency which is converted (19) to a voltage. When cage 1 rises to the level of coil 1, the inductance of coil 10 (and hence the frequency of (13)) alters to produce a positive voltage transient from (19) which is passed by a blocking capacitor (20) to operate a relay which signals unit 23. The apparent position signal (indicated on a dial 6) is derived from switches 26, 27 operated by long and short range cams 28, 29 rotated by the drive shaft 7. The signal from 26, 27 will reach 23 before or after the signal from 12 according as the slip is positive or negative (cage 1 respectively lower or higher than indicated on dial 6); if there is no slip then the signals arrive simultaneously, In the event of positive or no slip, the operator brakes normally, following the indication on dial 6; however, negative slip above a certain level is dangerous, and if this is detected by unit 23 it causes the winder control to apply the brakes and causes the alarm 30 to alert the operator. When the cage is descending, coil 10 may detect the position of a rising counterweight on the other end of cable 3, or of another cage if provided.

Title: Condition detecting control

Abstract: 1,125,373. Valves. H. K. BURCH, and L. W. BURCH. 22 Sept., 1965 [23 Sept., 1964], No. 40443/65. Heading F2V. [Also in Division H1] In a condition-responsive control device the control member of an electric switch or fluid flow valve, actuated by a condition detector, is assisted to its restored condition by a restoring force which is rendered effective only when the switch or valve is in its actuated position, thereby obtaining a very small differential for the controlled condition. In one example a snap-action switch contact 30, Fig. 1, is moved between a contact 34 and a stop 42a on a cantilever spring arm 44 engaged by a condition detector 50. A restoring force is applied by a leaf-spring 54 which is initially restrained away from the arm 44 by a bimetallic element 56 through which current flows when the contacts 30, 34 are closed. In operation, when the arm 44 has been moved towards the spring 54 by the detector 50 to break the contacts 30, 34 the bimetal element 56 cools and permits the adjusting screw 58 on spring 54 to urge the arm 44 to its restored condition. Dependent upon the spring settings the arm 44 may be caused to snap back either before or after any small restoring movements of the detector 50. The contacts may therefore be set to "hunt" or to return on a very small differential. Other examples are referred to in which the return spring 54 is restrained by a hotwire or by an electromagnet with a delay circuit or in which the bimetal element 56 is itself also the spring member 54. In a further particular example a snap-action pivoted contact 30i, Fig. 23, is directly engaged by both the condition detector 98i and the screw 58i of the restrained return spring system 52i on opposite sides of its pivot point.
