Abstract: 1,264,590. Harmonic gearing. USM CORP. 27 July, 1970 [5 Aug., 1969], No. 36265/70. Heading F2Q. In an harmonic drive mechanism, one of the surfaces of the gear members that are in contact during deflection is roughened so as to provide projections and the other surface is formed of an elastomeric material capable of being indented by the projections. As shown in Figs. 1 and 2, a flexspline 26, integral with an output shaft 28, carries teeth 30 which are forced into engagement with an elastomeric ring 36, secured to a housing 10, by an elliptoidal wave generator 20 secured to an input shaft 18. Instead of teeth 30, the flexspline 26 may be provided with knurling 32, Fig. 5, or serrations 34, Fig. 6. In a modification, a cup-shaped member 46, Fig. 3, is secured to an output shaft 44 and carries an elastomeric ring 48 for co-operating with spline teeth 50 formed on a flexspline 52 which is mounted in a fixed housing 40 by means of an elastomeric annulus 54. In another modification, an elastomeric ring 74, Fig. 8, is secured to a flexspline 70 and engages spline teeth 76 formed on the inside of a stationary housing 78. Fig. 9 shows a modification in which rollers 96, carried on arms 94 secured to a driving shaft 90, axially engage and deflect a face of a normally flat disc 100 mounted on an output shaft 106, thereby causing radial splines 102 on the disc 100 to engage an elastomeric ring 104 bonded to a housing 80. In a further modification, shown in Fig. 10, a wave generator comprises a pair of large balls 122, a pair of small balls 126, and two pairs of intermediate balls 124 located between a driving shaft 114 and a flexspline 134 secured to a casing 112. An output member 138 has a conical recess around the peripheral edge of which is secured an elastomeric ring 136 which is engaged by the flexspline 134, the contact pressure being determined by the axial position of input shaft 114.

Title: Automatic debris-removing device - for coarse screens in water purificn. stations
IPC: E02B8/02
Filed: 1974-04-02
Abstract: Automatic appts. is intended for the removal of debris retained by the coarse inlet screens in a water purificn. station. It comprises a frame formed by to uprights each carrying a bearing; these support a shaft to which a pivoting arm is attached. This has a balance wt. at one end and an ejection device, for the debris, at the other. The appts. is also fitted with a cam which is parallel to the circular grid which retains the debirs. The cam acts as a guide for the plate at the end of the arm so taht the springs are compressed as the arm moves upwards; these give a dynamic push to the debris, when the arm reaches the end of its stroke, which is pushed into the receptacle. Construction is simple and the appts. is reliable in action. The mechanism does not become jammed by a fragment held in the grid as the end of the arm is articulated.

Title: Automatic control device for generator or motor - provides continuous monitoring of armature and rotor energy absorption
IPC: G01R31/34
Filed: 1974-04-19
Abstract: The circuit controls motor and generator rotors and stators, providing a continuous check on the status of the windings insofar as the two windings may be considered marking up a single autotransformer. The stator winding is monitored by an ammeter, providing a manimum and maximum threshold, measuring the energy absorbed by the windings and providing a control output proportional to this level. Similarly using two of the armature laminations the state of the armature winding is monitored by an ammeter again providing an output proportional to the energy absorbed in the armature.
