IPC: G01D15/16
Filed: 1920-07-12
Abstract: 148,999. Arndt, M. June 21, 1919, [Convention date]. No Patent granted (Sealing fee not paid). Pens.-In recording- apparatus of the type giving a continuouslytraced curve on a travelling sheet or drum, a magnetic device is employed for maintaining the pen in continuous contact with the record paper. The device is shown applied to gas testing apparatus and consists of a permanent bar magnet 15 carried by a fitting 6 fixed to a gas container 1. An armature 14 is carried by a sleeve 10 which also carries a pen 12 and an ink container 11. The attraction between the armature 14 and the magnet 15 thus presses the pen 12 continuously on the record drum 20. In an alternative apparatus, a magnetic needle, attached to the sleeve 10, suitably oriented, keeps the pen against the record strip. The Specification, as open to inspection under Sect. 91 (3) (a) states also that a wick 25 dips into an ink reservoir 26 and by its capillary attraction keeps the pen 12 filled. This subject-matter does not appear in the Specification as accepted.

[Class 83 (i).] Moulding-machines.-Flasks o, u are drawn by two conveyer chains 3, Figs. 1 and 2, intermittently advanced by a pawl 7 and cylinder 6 by means of pivot pins 5 through a moulding- press 1. Upper flasks o rest on the lower flasks u but, before they reach the press, the upper flasks are transferred by a device 10 to a pattern plate pivoted to a truck 11 on rails 12 at the side of press. Both flasks are filled with sand and the pattern plate m with its flask o is moved laterally into the press over the flask u advanced by the conveyer. The press is then operated, the mid-section 13, Fig. 3, of the rails being separate and supported by levers 15 and weights to allow the plate m to move down. The plate m is then returned and the flask o is lifted off by another device 10 and placed on the flask u which has been again advanced by the conveyer. The next pair of flasks co-operate with a second plate located on the opposite side of the press. The moulds are filled with molten metal between the conveyer movements and when they reach the chain wheels 4, Fig. 1, the rear ends slide down an incline 18 to a lower run along which they are pushed. When each mould reaches the wheels 4A the free end is lifted by hooks 19, reciprocated by a catch 22 engaging the pivots 5 and a release incline 23. The mould passes non-return pawls 24 and is then released to fall thereon and thus discharge the contents on to a grid 9.

Abstract: 388,739. Motors. FERRANTI, Ltd. and HOLMES, W., Hollinwood, Lancashire. July 30, 1931, No. 21801. [Class 35.] Motors with unwound iron armatures; driving arrangements.-A synchronous motor comprises a stator and rotor having teeth or polar projections, a constant field system associated with the stator or rotor, and a cyclically varying field system, the rotor and stator teeth being so arranged that when both field systems are brought into action the rotor is caused to vibrate in tune with the cyclically varying field and synchronous rotation is initiated. Figs. 1 and 2 show two rotor discs x, y which are mounted on a common shaft and are associated with stator pole plates a, band c, d as described in Specification 379,383. Permanent polarity is given to the pole plates by a permanent magnet, or a continuous-current excited electromagnet. The stator and rotor teeth have the same pitch but the stator teeth are displaced so that complete magnetic alignment occurs only at A, Fig. 1. When alternating-current is supplied to the magnet - coil of the motor, torques are produced at B, C and D in the direction of the arrows during one half cycle and in the opposite direction during the other half cycle. No torques occur at A. In the construction shown, the anticlockwise torque on the discs is greater than the clockwise torque and the amplitude of the vibrations is greater than the tooth pitch so that the rotor rotates in the anticlockwise direction. The air-gap at A is made smaller than at other places so that the rotor will always stop in the position shown. The rotor and stator may have teeth of different pitch. A flywheel may be attached to the spindle by a spring of such a characteristic that a condition of resonance is produced when the spindle is oscillated at a frequency corresponding to the impressed alternating current. In a modification, Fig. 7, a permanent magnet u has staggered bifurcated arms and the air gaps at m, n are made smaller than at the other poles. The stator poles in this construction are formed on the edges of the cylinder and of the closing disc of a pot type electromagnet.
