Title: Improvements in epicyclic reducing gearing
IPC: F16H37/08
Filed: 1926-12-23
Abstract: 283,720. Shillito, B. J. Dec. 23, 1926. Variable-speed gearing yielding low speeds of the driven shaft comprises an epicyclic train controlled through an irreversible worm pair 32, 11 by a disc and roller variable gear. Planets 15, 15<1> nearly alike are carried by a worm-wheel 2 driven from a worm upon a driving-shaft 18. The planets 15 mesh with a control sun gear 8 connected by a sleeve 9 to the worm-wheel 11. The planets 15<1> mesh with a wheel 12 fast on a driven central shaft 3. The carrier wheel 2 is connected by its boss 4 directly with the disc 6 which coacts with a roller 25 slidably splined on a transverse shaft 19. The shaft 19 is carried by pivoted arms 20 biased towards the disc by springs 22. The shaft of the worm 32 is geared to the shaft 19 by a chain pair 36. The roller 25 is moved across the disc 19 by a hand-operated screwed shaft 30 with suitable end stops 39. The disc 6 has a central loose section 37 in the form of a stud. When the roller 25 engages the stud 37, it is not driven and the worm pair 32, 11 holds the control wheel 8 stationary. A slow differential motion is imparted to the wheel 12 and shaft 3. As the roller 25 is moved across the disc 16, this motion is progressively reduced, until it reaches zero in the end position of the roller.

Title: Improvements in or relating to waveguide components

IPC: H01M4/64
Filed: 1956-10-26
Abstract: 831,503. Waveguides. GENERAL ELECTRIC CO. Ltd. Oct. 25, 1957 [Oct. 26, 1956], No. 32809/56. Class 40 (8). In order to prevent radiation from a longitudinal or helical slot 2, Fig. 1, in a waveguide 1, an external member 4 is arranged adjacent the slot in such a manner that it forms with the waveguide wall 3 a transmission line supporting an evanescent mode of propagation. It is stated that the transmission line is excited in such a mode if where N1, N2 are respectively the refractive indices of the dielectric filling of the waveguide and the transmission line and #o, #c are respectively the free-space and cut-off wavelengths of the energy propagated in the H11 mode in the waveguide. The slot may be provided to prevent the waveguide wall from forming a shortcircuited turn when it is surrounded by a solenoid, as, e.g., in a Faraday-element gyrator. In an apparatus of this type (Fig. 2) the waveguide may comprise a tube 16 of polystyrene which is formed with an external conductive layer 15 by a chemical silvering process followed by electroplating. A longitudinal slot 20 and two terminal circumferential slots 22 (one only shown) are formed by sticking filaments on the tube 16 during the silvering process and stripping them off before electroplating. The longitudinal slot is co-terminous with an axial ferrite element comprising a number of cylindrical portions 14a and two tapered end-portions 14b arranged within the bore of the polystyrene tube 16. The ends of the tube are plugged with shaped polystyrene members 17. The longitudinal slot is covered by a conductive arcuate plate 24 spaced from the waveguide wall 15 by loops, strips or a helical winding 25 of, e.g., polyethylene. The plate 24 is held in position by a winding of tapes 26 and a solenoid 27 is wound over the tapes between cheeks 28. Coupling flanges 29 are electrically connected to the waveguide wall 15. Where the energy propagated in the waveguide is circularly polarized, operation over a broader band may be obtained by the use of a helical slot of rotary sense opposite to that of the wave. Four slots symmetrically arranged around the circumference of the guide may be used.

Abstract: 1,212,991. Automatic speed control. NATIONAL RESEARCH DEVELOPMENT CORP. April 11, 1968 [Jan.19, 1967; July 18, 1967], Nos.3005/67 and 32884/67. Heading G3R. [Also in Divisions G1 and H2] The speed of a commutatorless motor employing proximity switches to control the supply of current to the stator windings (see Division H2) is controlled by varying the on time of the switches in accordance with the deviation of the speed from a reference value. A voltage proportional to the speed of the motor may be obtained from a tachogenerator or alternatively a frequency signal proportional to speed may be obtained from the frequency of "switching on" one of the switches and this signal is compared with a reference frequency. As shown, oscillator switches 12 (a, b..p, q..) are controlled by sensor coils a, b..z to operate transistor switches 16 (a, b..p, q..) to supply current to the motor windings in sequence. Oscillator switch 12a is connected through capacitor 24 to a monostable integrator and multi-vibrator so that every time the switch is operated a pulse is produced which after integration produces a voltage on line 33. Changes in the value of this voltage after the conduction time of the switch oscillators to change the speed of the motor in a direction to restore the voltage to its original value. Alternatively the voltage could be applied to the 'keep alive' coils 10a, 10b which can completely shut down the oscillators during a period when the core is saturated and thereby controlling the admission of current to the stator windings.

The conical walls 4 may be provided with interlocking lips, Fig. 5 (not shown), and the discs secured to a sleeve keyed to the shaft 1. In the form shown in Fig. 6 the conical walls 22 continue into abutment flanged parts 23 which may be riveted or welded together, and outer conical flanges 24 form the V-grooves of the pulley. In a modification of this form, the bolts 8 are dispensed with, the rear wall is corrugated, and the discs are threaded on to a reduced portion of the shaft 1 and clamped between a flat disc and a nut screwed on to a threaded portion of the shaft. Pulleys of large diameter may be formed of pairs of discs secured to a shaft by the deformation of smaller dished discs interposed therebetween, axial clamping bolts being passed through the assembly. A pair of large discs may be replaced by a single disc having secured thereto an annular conical flange. In the Specification as open to inspection under Sect. 91, the discs may be provided with radial slits or corrugations extending outwardly from the central aperture. This subject-matter does not appear in the Specification as accepted.
