Title: Tone wheel to produce frequency-modulated low frequency oscillations
IPC: G10H3/08
Filed: 1952-02-08
Abstract: 694,937. Dynamo-electric machines. STANDARD TELEPHONES & CABLES, Ltd. Feb. 8, 1952 [Feb. 20, 1951], No. 3380/52. Class 35. For producing sinusoidally frequency-modulated low-frequency oscillations for actuating alarm apparatus, testing acoustic devices or serving as intermediate carriers in plants of rotary radio beacons, similar magnetic elements of width b are spaced around the circumference of a wheel at equal circumferential distances but displaced axially to form a sinusoidal curve. As the wheel rotates at uniform speed the elements pass under a permanently magnetized polepiece lying at an acute angle to the axial direction at varying distances across the polepiece, whereby a frequency-modulated voltage is induced in a coil wound on the polepiece. In a modification, Fig. 2 (not shown), the magnetic elements may be studs with projecting ends arranged eccentrically in a disc. The polarized horseshoe shaped polepiece embraces the disc to a depth greater than twice the eccentricity plus the diameter of one stud, and may be narrower towards the centre of the wheel to produce a voltage of constant amplitude despite the varying speeds of the studs. The wheel should be of insulating or poor conducting material.

Title: Electromagnetic actuator
Inventor: HADEKEL REUBEN
IPC: H01F7/16
Filed: 1959-01-30
Abstract: 912,858. Electromagnets. SPERRY GYROSCOPE CO. Jan. 15, 1960 [Jan. 30, 1959], No. 3408/59. Class 35. In an electromagnetic actuator, e.g. for an hydraulic valve, an armature has a portion which is continuously saturated while the rest of the magnetic material is not, which portion forms part of a figure of eight configuration whereby it is common to two flux paths, and air gaps on either side of the armature are arranged so that as one increases the other decreases; means are provided to vary differentially the flux in the respective air gaps, and a third flux path transverses the poles only of the armature. As shown in Fig. 1, the armature 1 is slidable on a square rod 4 between the faces of two C-shaped members 2, 3, which carry polarizing windings 7, 8 and signal windings, 9, 10. The flux due to 7 and 8, in the same direction in the armature 1, is sufficient to saturate it at a waisted portion 11; hence the flux through that portion is constant and variations due to the signal coils, which are wound differentially, cause an increased flux in the gaps in one side of the armature and a corresponding decrease in those on the other. The armature is thus attracted one way or the other by an amount proportional to the signal current. The motion is opposed by springs 5, 6 of a stiffness sufficient to ensure stability, unless the load (not shown) itself is satisfactory in this respect. An alternative construction (Fig. 2, not shown), is essentially the solid of revolution obtained by rotating the shape of Fig. 1 about an axis through the rod 4, when two pot-magnets are formed, face-to-face, with a disc-shaped armature between them. In a second alternative, Fig. 3, the armature 41 is H-shaped and is pivoted about an axis 44, and the " eight " configuration is completed by two fixed straight members 42, 43 which carry the windings. In a modification of this arrangement the armature comprises a plate (Fig. 5, not shown) with upturned corners forming poles and with slots to cause the necessary reduction in area. In all cases the polarizing winding may be replaced by a permanent magnet, or a single pair of windings may carry the algebraic sum of the polarizing and signal currents.

Abstract: 929,712. Automatic speed control. M. C. PFISTER. Oct. 29, 1959 [Nov. 27, 1958], No. 4019/62. Divided out of 929,711. Class 38 (4). [Also in Groups XXII, XXIII and XL (b)] Sawing or shearing apparatus is made to move at the same speed as a billet on a conveyer at a predetermined relative position by a photoelectric device which measures deviation from said relative position and accordingly controls the reference voltage of a Ward-Leonard unit controlling the apparatus speed. Devices 44 and 45 produce voltages proportional respectively to the instantaneous and predetermined relative positions of the apparatus and the billet, and the difference drives a servomotor 53 coupled to the tapping of potentiometer 51. The voltage tapped off is indicative of the desired apparatus speed for the existing relative position, and the difference between it and the voltage of a tachometer 50 coupled to the motor 49 driving the apparatus, drives a servomotor 52. Servomotor 52 varies the excitation of a generator 48 supplying the motor 49.

Filed: 1969-01-23
Abstract: 1,244,792. Programmed control of machine tools. GENERAL ELECTRIC CO. Jan.23, 1969 [Feb. 2, 1968], No.4021/69. Heading G3N. A control system for co-ordinate movements of machine elements relative to a work-piece comprises commanding independent rates of movement along each element path, resolving into co-ordinate components, comparing independent rates along a common axis and modifying the commanded independent rates to conform the rates on the common axis with one common rate. As shown, feedrate signals, indicative of movements along two paths XY, XV are received on connections 13, 14 from a feedrate pulse multiplier, as disclosed in Specification 1,019,896, by a signal transmission control 10 which in response to signals on inputs 15, 16 momentarily interrupts the transmission of the feedrate signals to outputs 11, 12. The feedrate signals for each path is fed to an appropriate function generator 17, 18 wherein component axis feedrates are derived which are fed to command counters 25-27 for the control of machine drives. Since the X axis movement is common to both paths a component feedrate is derived from function generator 17 only for the X command counter, but the derived X axis component feed rates from both generators are fed to a gated reversible counter 31 on lines 32, 33. The counter 31 monitors the X axis component feedrates and supplies an inhibiting signal over a line 15, 16 to stop the basic XV or XY feedrate signals when the count is out of a null or balanced condition and above a limit +K or below a limit -K.

Title: Separation by selective catalytic chemical reactive process
IPC: B01J29/70
Filed: 1962-02-02
Abstract: A hydrocarbon is recovered from a mixture containing components of different molecular shape or size by selective conversion of at least one of the components by contact with a crystalline aluminosilicate zeolite having catalytic materials incorporated and having a pore size large enough to admit certain components which are accordingly selectively converted and small enough to exclude others which are unchanged and separating the converted from the unconverted materials.  The mixture may contain, for example, linear and non-linear components and a 5-13 <\>rA molecular sieve may be used. The conversion effected may be cracking, hydrocracking, hydrogenation, dehydrogenation, alkylation, dealkylation, oxidation or isomerization.  Where possible the converted component after separation may be reconverted to its original form.  The catalyst may be in the sodium form or may be base exchanged to introduce Ca, Mg, Ag, Cu, Hg, Cd, Ni, An, Co, Zn, Sr, Pt or rare earth metals or may be converted to the hydrogen form and is modified to introduce other catalytic materials, e.g. Zn, Co, Ni, Ag, or a platinum metal. The process may also be applied to non-hydrocarbon mixtures when one component may be converted to and recovered as a hydrocarbon. In the Examples: (1) using a 5 <\>rA molecular sieve containing platinum, n-butenes in a mixture with isobutene are selectively hydrogenated to n-butane and the product separated into isobutene and n-butane; (2) similarly 2-methylbutene-1 is recovered from a mixture with pentene-1 which is converted to and recovered as n-pentane.  Reference has been directed by the Comptroller to Specifications 886,716, 930,513 and 979,381.
