Abstract: 419,835. Controlling motors. FLEINER, M., 5, Gempenstrasse, Basle, Switzerland. July 29, 1933, No. 21369. [Class 35.] Yokes.-The stator of a squirrel-cage motor or other machine without salient poles is formed with a gap or other region of high reluctance into or against which a movable portion is drawn when the current is switched on so as to release a brake, or operate a low voltage cut-out or a starting rheostat, a delay-action device being provided where necessary. Figs. 1 and 2 show a stator 1 formed with a gap 4 and a pivoted portion 5. To prevent the gap 4 from being short-circuited by the casing 8 the latter is separated from the stator by non-magnetic pieces 9 or may be formed with a gap 10. The member 5 may be connected to the device to be operated by a toggle, but in the form shown is provided with a cam-surface 12 operating a lever 14 to move the rotor longitudinally and thus release it from a brake-member 19. Instead of a gap the stator may be formed with a narrow portion, the flux across which may be decreased by shortcircuited windings, which may be interrupted by the movable member. To concentrate flux on the portion of the stator where the movable member is situated radial slots are formed in the stator. Arrangements with two movable members and a member sliding longitudinally are also described.

Title: Improvements in systems for transmission of coded data
IPC: G08C19/28
Filed: 1960-06-17
Abstract: 907,333. Electric selective signalling. STANDARD TELEPHONES & CABLES Ltd. June 17, 1960 [June 19, 1959], No. 21371/60. Addition to 892,552. Class 40 (1). In a signal representing a series of binary elements there are two different frequencies, the frequency of the signal being changed at the beginning of each bit period and for one of the binary elements (" 1 " say) there is a further change in the middle of the period. An oscillator OSC, Fig. 1, produces pulses which operate a trigger BA to give square output pulses A, Fig. 2, which pass to trigger BB operating at half frequency to produce pulses B. Pulses A also pass to a pulse former FP1 to give short pulses P1 and pulses B in pulse formers FP2, FP3 produce pulses P2 and P3. A generator GE has two frequencies F1 or F2 and always changes from one to the other on receipt of the P2 pulse at the beginning of the bit period. The P3 causes a second frequency change in the middle of a bit period if the bit is " 1." Data from source Si appears as positive and negative voltage I there being a change at the beginning of each bit period and also in the middle for " 1 " signals, which are produced under the control of pulses P2 and P3 as described in the parent Specification. These control the frequency of the generator GE as shown at E, the arrangement being such that the change of frequency is made at the time when the energy content of the circuit is zero. Where the frequency change is effected by changing the inductance of an L-C circuit the energy is zero when the voltage is a maximum and the current is zero. An extra inductance can then be inserted without incurring transients. If the capacity is altered the moment of zero energy is when the voltage is zero. The generator GE changes frequency by changing inductance and it is necessary that the pulses P2 and P2 coincide with maxima of the curve E. The generator starts at zero when pulse P1 occurs and at either frequency an odd number of quarter waves occur between a pulse P1 and the following pulse P2 or P3. The oscillator consists of capacitor Cd3, Fig. 3, and an inductance comprised by the upper left-hand winding of transformer Tf2, the left hand winding of transformer Tf3 and the lower winding of Tf2, The transformers are coupled via the base of transistor TR1 to transmission transformer Tf1. 1. The greater part of the inductance is in the windings of transformer Tf2 and the winding of transformer Tf3 is short-circuited to alter the frequency of oscillation by a signal from the data source Si acting through transistor Tr2. The synchronizing pulses P1 are applied at FP1 and, by causing diodes Di1 and Di2 to conduct short-circuit the oscillator. The oscillator starts from zero at the end of the pulse P1, the frequency being determined by the data signals I.

Suitable salts are the salts of the alkalies, alkaline earths, or heavy metals which are soluble in liquid ammonia.  The ammonia may be removed from the structureless mass which is then soluble in water to form a solution capable of being spun.  Examples are given wherein the following salts are used: potassium thiocyanate, magnesium nitrate, potassium nitrate, calcium nitrate, and copper nitrate.
