Title: Improvements in or relating to carrier wave electric signalling systems
IPC: H03F1/54
Filed: 1936-06-26
Abstract: 477,358. Phase - difference and frequency measurements. STANDARD TELEPHONES & CABLES, Ltd., and JACOBSEN, B. B. June 26, 1936, No. 17821. [Class 37] [Also in Group XL] Carrier-wave systems provided with alternative wave sources are arranged so that switching from one source to another can be effected without discontinuity. A multiple-spring switch 5 ... 11 when in the position shown connects the source 1 to the useful load 3 and the spare source 2 to a dummy load 4. When the switch is operated by raising the lowermost spring 5, contact between 5, 6 connects both sources across both loads. Further upward movement of the springs 5 operates through the insulating bars 18, 19 to open the contacts 8, 9 and 10, 11 and the latter serve to disconnect the source 1 from the useful load 3 and the source 2 from the dummy load 4. In order that the switch may be operated at a suitable moment when the sources are in agreement as regards amplitude, frequency, and phase, a rectifying meter 16 is coupled differentially by a transformer 14 to circuits connected across the respective loads 3, 4. A steady zero reading indicates a suitable moment for switching. The meter 16 may be provided with contacts which operate through relays with time delay to perform the switching of the sources automatically. To reduce coupling between the sources 1, 2 they may be connected to the loads through neutralized amplifiers. Coupling caused by the secondary circuit of the transformer 14 is reduced by a resistance 17 in the common portion of the primary circuits and series resistances 12, 13 in each branch. By providing switches in the primary circuits, the meter 16 can be used to indicate the voltage in either branch.

Title: A mechanical transducer
IPC: G06G3/00
Filed: 1956-06-12
Abstract: 839,322. Linkwork. HARRIS-INTERTYPE CORPORATION, [formerly HARRIS-SEYBOLD CO.]. June 12, 1956 [June 16, 1955], No. 18100/56. Class 80 (3). [Also in Group XXIX] In a mechanical transducer having a digital input and an analogue output variable by discrete units corresponding to the total input, a unitary rigid transmission member such as the three-armed lever 60, is acted on by three input members comprising spaced parallel fluidoperated plungers 33a, 33b, 33c. The plungers may be considered as acting at points A, B, C of a triangle ABC, Fig. 5, these points being adjacent the ends of the arms 61, 62, 63 of the lever 60. As shown in Fig. 5, the triangle ABC is rightangled isosceles triangle with equal sides AC, BC, and the output element 64 is located at a point D on the perpendicular from C to AB such that the ratio c/CD+c is twice a/AC or b/BC. If then the stroke of the plunger 33a is arranged to be half that of plungers 33b and 33c, single displacements of each of the plungers 33b, 33c separately produce displacements 2x and 4x of the output member 64, where x is the displacement of the plunger 33a. The displacements x, 2x thus correspond to the first three places on a binary scale. Similarly further plungers 33d, 33e co-operating with the output member 64 on a second three-armed lever 65 give rise individually to displacements of 8x and 16x of an output member 67 and still further plungers 33f, 33g acting with the output member 67 on a third three-arm lever 66 give rise individually to displacements of 32x and 64x of a final output member 70. By utilizing all the possible combinations 127 consecutive increments of x are possible. If the point D is arranged on the line AB, the displacements of C are not summated. Similarly if the point D is on a projection of the line AB, the displacements of one of the points A, B, say A, are added to the total and those of the other point B subtracted therefrom. In other arrangements, the displacements of two of the three points are added and those of the third point subtracted or vice versa. In Fig. 10, a transmission member 100 engages the output elements D, D<SP>1</SP>, D<SP>11</SP> at the centroids of equilateral triangles ABC, A<SP>1</SP>B<SP>1</SP>C<SP>1</SP>, and A<SP>11</SP>, B<SP>11</SP>, C<SP>11</SP>. The points D, D<SP>1</SP>, D<SP>11</SP> themselves form an equilateral triangle with the output member 101 at its centroid. Unit displacement of any one of the nine points A, B, C, A<SP>1</SP>, B<SP>1</SP>, C<SP>1</SP>, A<SP>11</SP>, B<SP>11</SP>, C<SP>11</SP> thus produces a displacement of the output member 101 equal to one ninth of the total possible displacement.

[Class 106 (i)] The apparatus of the parent Specification is modified to obtain the algebraic sum of the rotations of a shaft a which may turn clockwise and anticlockwise. When turning clockwise, a cam b on the shaft closes in turn pairs of contacts d, h and c, e, thus connecting respectively two half-wave rectifiers j, i to an A.C. supply n, one rectifier producing half-waves of opposite sign from those produced by the other. The rectifiers are thus connected to a driving device k comprising a rotor adapted to be advanced by D.C. pulses of alternating polarity, the rotor driving a counter through a differential gear p. When the shaft a turns anticlockwise, contacts d, g and c, f are closed in turn to connect the rectifiers j, i to another similar driving device m which through the differential gear drives the counter in the opposite direction. As an alternative to the cam b, a toothed wheel b, Fig. 2, may rock pivoted contacts c, d, pressed towards the wheel by blade springs r and mounted on pivots q engaging slots in the contacts. The arrangement is such that only one contact is closed at one time. Also, when the wheel b is turning, e.g. clockwise, the contact d cannot accidentally engage the upper contact g.
