Abstract
Abstract A multiple pulse generator comprises a plurality of axially straight, prestretched wire segments uniformly twisted helically and enclosed in a dielectric body to form a cylindrical core. A wire coil is wound around the core. When a magnetic field of variably intensity impinges on the wires a series of pulses are generated in the coil. The magnetic field can be created by passing an electric current of varying magnitude through another coil wound on the core, or by moving laterally a permanent magnet disposed adjacent to the core.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
103 words
A multiple pulse generator, comprising a plurality of axially straight magnetic wire segments of equal length, each wire being prestretched and uniformly twisted helically; a dielectric body securing the wires in a bundle in fixed positions laterally adjacent to each other to form a cylindrical core; and a conductive wire coil helically wound around the core, whereby a series of electrical pulses will be generated in the coil when the wires in the core are subjected to a magnetic field of gradually changing intensity, the maximum number of pulses in said series being equal to the number of wire segments in the core.
Claim 2
Dependent Claim
103 words
A multiple pulse generator, comprising a plurality of axially straight magnetic wire segments of equal length, each wire being prestretched and uniformly twisted helically; a dielectric body securing the wires in a bundle in fixed positions laterally adjacent to each other to form a cylindrical core; and a conductive wire coil helically wound around the core, whereby a series of electrical pulses will be generated in the coil when the wires in the core are subjected to a magnetic field of gradually changing intensity, the maximum number of pulses in said series being equal to the number of wire segments in the core.
Claim 3
Dependent Claim
21 words
A multiple pulse generator as defined in claim 1, further comprising means adjacent to the core for creating said magnetic field.
Claim 4
Dependent Claim
41 words
A multiple pulse generator as defined in claim 2, wherein the last named means comprises another conductive wire coil wound around the core to create said magnetic field when an electric current of variable magnitude is passed through said other coil.
Claim 5
Dependent Claim
45 words
A multiple pulse generator as defined in claim 2 wherein the last named means comprises a permanent magnet spaced laterally from said core, and means for changing the spacing between the magnet and core for subjecting the core to the magnetic field of changing intensity.
Claim 6
Dependent Claim
50 words
A multiple pulse generator as defined in claim 1, further comprising a support for the core; a permanent magnet, means movably supporting the magnet with respect to the core; and means for moving the magnet laterally of the core to subject the core to the magnetic field of changing intensity.
Claim 7
Dependent Claim
57 words
A multiple pulse generator as defined in claim 1, further comprising a permanent magnet; a flexible dielectric block enclosing both said core and magnet with a magnet spaced laterally from the core, whereby a magnetic field maintained by the magnet sweeps the core when the magnet and core are moved relatively to each other inside said block.
Claim 8
Dependent Claim
27 words
A multiple pulse generator as defined in claim 6, further comprising a button on the block arranged to move the magnet laterally with respect to the core.
Claim 9
Independent Claim
75 words
A method for generating a series of pulse, comprising the steps of stretching and twisting under tension a plurality of magnetic wire segments; assembling the wire segments into a bundle; enclosing the segments in a dielectric body to form a cylindrical core; winding a conductive wire coil around the core; and subjecting the wire segments in the core to a magnetic field of changing intensity to generate a series of electrical pulses in said coil.
Claim 10
Independent Claim
75 words
A method for generating a series of pulse, comprising the steps of stretching and twisting under tension a plurality of magnetic wire segments; assembling the wire segments into a bundle; enclosing the segments in a dielectric body to form a cylindrical core; winding a conductive wire coil around the core; and subjecting the wire segments in the core to a magnetic field of changing intensity to generate a series of electrical pulses in said coil.
Claim 11
Dependent Claim
68 words
A method for generating a series of pulses as defined in claim 8, wherein the step of subjecting the wire segments to said magnetic field comprises the further steps of placing a permanent magnet adjacent to the core; and varying the spacing between the magNet and core so that the magnetic field maintained by the magnet sweeps the core with variable intensity while said spacing is being varied.
Claim 12
Dependent Claim
58 words
A method for generating a series of pulses as defined in claim 8, wherein the step of subjecting the wire segments to said magnetic field comprises the further steps of winding another conductive wire coil around the core; and passing an electric current of variable magnitude through said other coil to generate said magnetic field of changing intensity.
