Filed: 1924-03-15
Abstract: 212,941. Compagnie Electro-Mecanique. March 16, 1923, [Convention date]. Gear-cutting. - In a machine for cutting toothed gears by hobs, a device is provided for recording any wear which may have occurred in the driving mechan. ism of the machine during the hobbing operation, the record then being used for deducing the errors made in cutting the teeth. In the arrangement i ll u s - trated the work-plate carrying the gearblank J is driven by worm gearing A on a shaft X<1> which is driven from the primary motor N by gearing T<2>. The feed is controlled by a shaft X<2> and the hob K is driven by a shaft X<3>, differential gearing being provided at D<1>, D<2>. A record-carrying drum T is rotated from the shaft X' by speed multiplying gearing E and a style P is moved in a direction parallel to the axis of the drum by a screw V driven by reduction gearing S. The record is made by an electric spark between the style P and the drum T, the style being insulated and connected by a wire F to a lever L of a magneto M. The lever is. tripped by a part B on the work plate once each revolution. The gearing is such that if no wear takes place in the worm gear A during the hobbing operation, the perforations on the record card will follow the line of a generatrix of the cylinder T. Deviation from the line of a generatrix will indicate the amount of wear, and from this the extent of the error in the hobbed teeth may be deduced. The recording drum T may be driven by a differential connected to the shafts X<2> X<3> in which case errors due to wear throughout the whole transmission are accounted for.

Abstract: 908,237. Etching text on film. ERTNAES, O. I. Feb. 26, 1959, No. 6784/59. Class 98 (2). In a method of producing explanatory texts on photographic film by masking portions of the film and then etching through the unmasked portions, means are provided for mixing air with the etching liquid, and directing the mixture at the film, thus removing minute gas bubbles adhering to the film which tend to prevent the etching action. In the form shown, the film strip 1, which has been covered with a protective layer removed at those portions corresponding to the lettering to be marked thereon, is passed in serpentine fashion over guide rollers which carry it through the etching liquid 5. A tube 6 passes into the liquid, and has perforations 7 arranged below the lower guide rollers. When compressed air is blown through tube 6, air bubbles emerge through the perforations, and are impelled against the film. In the arrangement of Fig. 2 (not shown), the same effect is obtained by a series of rotating vanes, which dip into the etching liquid and throw a mixture of liquid and air up against the film.

IPC: G01C19/36
Filed: 1961-02-24
Abstract: 930,695. Gyro-magnetic compasses. S. SMITH & SONS (ENGLAND) Ltd. Feb. 23, 1962 [Feb. 24,1961), No. 6796/61. Class 40 (1). A gyro-magnetic compass system for an aircraft has a servo-loop including a gyroscope 1, a course defining device to generate signals representing the aircraft heading relative to a reference direction provided by the gyroscope, a magnetic detector 17 generating a signal representing the aircraft heading relative to the direction of the horizontal component of the earth's magnetic field, means 13 for generating a discrepancy signal representing any difference between the two aircraft heading signals, and means for controlling the course defining device to reduce any discrepancy towards zero, and the system further includes means 25 (Fig. 2) for measuring the vertical component of the earth's field, means 21, 22, 24 for modifying the signal in accordance with the angle of tilt of the detector caused by Coriolis' force and means for combining the modified signal with the signals from the magnetic detector so as to compensate for errors thereof due to tilting by Coriolis' force. Associated with gyro 1 is a synchro transmitter 3 connected to synchro control transformer 7 arranged in a subsidiary seivo loop 10, 11 so that the position of shaft 9, registered at 12, indicates the aircraft heading relative to the gyro reference. Magnetic heading detector 17 is gimbal mounted to normally lie horizontally and feeds to the stator windings of synchro resolver 14 a signal representing the aircraft heading relative to the horizontal component of the earth's field. Shaft 9 positions the rotor of rotor 14 and any discrepancy output is applied to torque motor 2 to precess the gyro and reduce the discrepancy. Alternatively the resolver output may be applied to a motor driving one part of a differential synchro between transmitter 3 and transformer 7. A corrector circuit (Fig. 2) is connected in series with transverse winding 16 of detector 17 and includes, in series with vertical field coil 25, a potentiometer 24 tapped in accordance with the aircraft speed V. Further potentiometer 22 is tapped in accordance with the sine of the latitude A of the aircraft. The angle of tilt of detector 17 caused by Coriolis' force is stated to be proportional to V sin # and the consequent error in output from the magnetic detector is stated to be proportional to the sine of this angle, or since it is small, to the angle itself. The speed and latitude may be set manually or automatically. The speed-setting potentiometer may be a switchable network, rather than continuously variable, and a network of this type, having substantially constant input and output impedance is described (Fig. 3, not shown).
