Title: A Stepping Motor.
IPC: H02K37/14
Filed: 1966-06-17
Abstract: 1,154,692. Dynamo electric machines. SIEMAG FEINMECHANISCHE WERKE G.m.b.H. 17 June, 1966 [19 June, 1965], No. 27292/66. Heading H2A. A stepping motor for use in data processing apparatus, is constructed such that the rotational acceleration of the rotor is substantially sinusoidal over each step movement by providing between the main poles an intermediate stator pole which is energized to accelerate the rotor and de-energized when the main poles are again energized to locate the rotor at the end of the step. The motor has a cruciform polarized rotor 4 co-operating with 8 stator poles, S1-S8, each having two windings W1, W2 connected to form a starting field circuit I and a locating field circuit II wherein the windings are interconnected to provide, when energized, main poles S2, S4, S6, S8 having opposite magnetic polarities and intermediate poles S1 S3, S5, S7 of neutral polarity. In operation the energization of circuit I is reversed by contacts r12, r13 thereby making the main poles of neutral magnetic polarity and the intermediate poles of opposite magnetic polarity to accelerate the rotor which rotates (clockwise as shown) and overshoots the magnetic axis; at the end of the overshoot the polarity of circuit II is reversed to locate the rotor in position. Stator winding energization is controlled by means of a shaft mounted commutator disc (6), Fig. 3 (not shown), having a printed conductive pattern which co-operates with brushes (8), Fig. 1 (not shown), secured in a plate (12) which is angularly movable to alter the position of the brushes relative to the stator poles. An electromagentic brake (10), (11) is also provided and controlled by track (63) on the commutator disc. In an alternative construction a perforated disc and photo-cells operating electronic switches may replace the commutator arrangement. Provision is made for the motor to continuously rotate at high speed by reversing the polarity of circuit II earlier to provide an accelerating rather than a locating torque with the brake disconnected by relay (r21).

Abstract: 232,659. Taggart, J. Scott-. Nov. 1, 1923. Aerials; coupling aerial and detector circuits.-In order to maintain the tuning of a receiver substantially constant for different aerials, a small condenser C<1>, Fig. 1, is inserted in series with the aerial inductance L and parallel tuning condenser C<2>. The condenser C<1> is preferably fixed and has a capacity value less than that of the ordinary aerial system, preferably about 0.0001 mfd. so as to reduce the effective inherent capacity of the aerial as a whole below this figure, thus making the condenser C<2> the predominant tuning factor. In Fig. 2 the aerial and earth terminals of the receiver are shunted by a third condenser C<3> preferably having a capacity of 0.0002mfd. This increases the total capacity, thereby decreasing the effect of any slight variation in the natural aerial capacity. According to the Provisional Specification the aerial inductance and variable tuning condenser may be inserted in series across the shunt condenser C<3>.
