Abstract: 1,024,948. Indicating-apparatus. AMPHENOL CORPORATION. June 5, 1964, No. 23473/64. Heading G1J. Apparatus for indicating the setting of the shaft 20 of a multiple turn potentiometer 18 comprises first and second dials 23, 25 coupled by a speed changing transmission 61, 62. One dial 23 for indicating fractions of a revolution bears numbers on a transparent face through which numbers on the second dial 25 are visible and is incorporated in a setting knob 43 attached to a hub 48 fixed to the shaft 20. The hub 48 is threaded to receive a nut 36 clamping a mounting shell 29 to a panel 19 supporting the potentiometer. An index shell with a mark 24 has its rearwardly open rim formed with a rib 57 and a lug 54, the latter interlocking with a groove 55 in one of three locking dogs 56 on the front face of the shell 29 and the dogs snapping over the rib 57, thereby fixing the index shell. Full turns of the shaft 20 are indicated by the dial 25 mounted on a shell 58 which is free to rotate in the index shell under torque developed in its twelvetooth gear 61. The gear 61 meshes with an eleventooth orbital gear 62 mounted on a cam 52 formed eccentrically on the hub 48, rotation of the gear 62 being prevented by a tang 63 received in a groove 64 on the mounting shell 29. A brake operated by a knob 40 comprises an 0-ring 41 of resilient material such as rubber mounted on the shell 29 against a rib 66. The ring expands radially against serrations 67 inside the knob 43 when axial pressure is applied thereto through the relative rotation of a cam shoulder 71 inside the knob 40 and a cam follower ring 72. The ring 72 is held against rotation by its lug 74 which can slide axially in a slot 75 in the shell 29 and the knob 40 can be turned within the limits of a circumferential slot 77 in the shell 29 co-operating with a lug 76 inside the knob 40. When expanded in clamping action, the ring 41 also prevents ingress of dust.

Abstract: 295,726. Pironneau, E. L. F. M. Aug. 19, 1927, [Convention date]. Controlling different functions by same handle or lever; automatic power control.-The Specification as open to inspection under Sect. 91 (3) (a) describes the steering and vertical adjustment of the forward end of a motor plough, harvester, or other implement as performed by means of the same hand-wheel mounted outside the axis of the pivotal connection between the tractor and the implement, and describes the provision of a breakable part to allow of release and declutching of the tractor when an obstruction is met with. To put the hand-wheel 16 into position for acting as a steering-wheel it is pulled outwards until dogs on its shaft 15 engage with a worm 17. For raising the front end of the plough the hand-wheel is pushed inwards until other dogs engage with a, bevel-pinion 19. In either position the shaft 15 is locked against longitudinal movement by partially rotating a cap 25 on a casing 22. Rotation of the cap 25 by means of handles 27 causes two plates or stops to move into or out of one or other of two circular channels 23, 24 on the shaft 15. The worm 17 drives a pinion on a shaft carrying another pinion gearing with a toothed sector on the tractor. The casing carrying the steering-shaft 15 is connected to the tractor by a vertical pivot pin 39. The attachment piece 46 at the front end of the implement is mounted in a fitting 45 connected by a vertical pivot pin 49 to a support 47 adapted to slide on vertical guides 48 on the tractor. The fitting 45 is raised or lowered by the rotation of a, screw 42 carrying a bevel pinion 40 engaging the bevel pinion 19. A spring 52 is inserted between the fitting 45 and a washer 50 on the attachment piece 46. When an obstruction is met with the pin 51 securing the washer 50 breaks and a nut 53 at the end of the attachment piece 46 engages a bell-crank lever 54 which operates the clutch mechanism through a Bowden wire. A stirrup 58 attached to the piece 46 may carry a pin or finger 57 adapted to slide through .the fitting 45.

The outputs of two harmonic generators are combined in a plurality of mixers to produce desired combination frequencies, one of the generators comprising a plurality of delay elements, e.g. shift register stages, one stage of which is conditioned by two or more other stages. In the telephone carrier generator shown, the output of a 496 kc./s. oscillator 1 is converted to pulses at 2 which are fed through a bi-stable divider circuit 3 to produce 248 kc./s. pulses. These are fed to a shift register 4 having feedback as described in the parent Specification to produce a pulse sequence having a basic sequence repetition frequency of 4 kc./s. Filters 6, 7 and 8 select desired harmonics of this frequency. 142 kc./s. pulses are provided by a divider 9 and these are mixed at 10 with the shift register output to provide odd harmonics for selection by filters 11 and 12. A 56 kc./s. signal is selected at 13 and mixed with the 496 kc./s. signal to produce 880 kc./s. which is fed to a further shift register having feedback arranged to produce a 16 state cycle and has a harmonic rich 55 kc./s. signal. Eight mixers 19 combine this with the 8 kc./s. output to provide other carrier frequencies.
