Abstract
Abstract Electrical relays of the type having an armature positioned for selective contact between contact faces of pole pieces within a glass envelope under the influence of electrical flux, with or without biasing permanent magnets. Low reluctance material is connected to the exterior armature stem and extends around opposite sides of the relay and has spaced ends, each of which is magnetically coupled to one of the pole pieces of the relay. Operating coils are positioned around the low reluctance material on opposite sides of the relay envelope and are within the side projection outline of the envelope.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
189 words
A relay of the type having an armature and pole pieces positioned within a glass-like envelope with the pole pieces and armature stem extended outwardly beyond the confines of the envelope at opposite ends thereof and in which electrical flux is utilized to bias the armature into contact with at least one of the pole pieces to selectively make and break contact with the pole piece contacts of the relay within the envelope, the improvement comprising elongated wire-like magnetic core material extending along both opposite sides of the exterior of the envelope and having opposite end portions, one end portion of said material on each side of said envelope being closely adjacent to and in magnetic contact with the portion of the armature stem outside of the envelope and the other end portion of said material on each opposite side of said envelope being extended to a position closely adjacent one pole piece, and operating electrical coils surrounding said material and positioned on opposite sides of said envelope whereby electrical flux induced in said strips imparts one polarity to the pole pieces and an opposite polarity to said armature.
Claim 2
Dependent Claim
189 words
A relay of the type having an armature and pole pieces positioned within a glass-like envelope with the pole pieces and armature stem extended outwardly beyond the confines of the envelope at opposite ends thereof and in which electrical flux is utilized to bias the armature into contact with at least one of the pole pieces to selectively make and break contact with the pole piece contacts of the relay within the envelope, the improvement comprising elongated wire-like magnetic core material extending along both opposite sides of the exterior of the envelope and having opposite end portions, one end portion of said material on each side of said envelope being closely adjacent to and in magnetic contact with the portion of the armature stem outside of the envelope and the other end portion of said material on each opposite side of said envelope being extended to a position closely adjacent one pole piece, and operating electrical coils surrounding said material and positioned on opposite sides of said envelope whereby electrical flux induced in said strips imparts one polarity to the pole pieces and an opposite polarity to said armature.
Claim 3
Dependent Claim
36 words
The structure of claim 1 in which said operating coils and material have dimensions such that they are within the outline dimensions of the envelope when the envelope is viewed from the side having said material.
Claim 4
Dependent Claim
29 words
The structure of claim 1 characterized by and including permanent magnet material associated with the pole pieces so as to provide selected permanent magnetic polarities for the pole pieces.
Claim 5
Dependent Claim
32 words
The structure of claim 1 wherein the magnetic core material has electrical insulation to prevent completion of an electrical circuit through the core material and to the armature stem and pole pieces.
Claim 6
Dependent Claim
161 words
A relay of the type having an armature and pole pieces positioned within a glass-like envelope with the pole pieces and armature stem extended outwardly beyond the confines of the envelope and in which electrical flux is utilized to bias the armature into selective contact with one or the other of the contact faces of the pole pieces within the envelope, the improvement comprising electrical operating coils positioned on opposite sides of the envelope and within the side projection outline of the envelope, low reluctance material extending through ends of said coils and magnetically coupled to the exposed armature stem, said low reluctance material having portions extended from the other ends of said coils and in closely spaced and magnetically coupled relation to said pole pieces, the electrical connections of the coil and the magnetic arrangement being such that the electrical coils impose one polarity on the armature, when said coils are energized, and the opposite polarity on said pole pieces.
Claim 7
Dependent Claim
161 words
A relay of the type having an armature and pole pieces positioned within a glass-like envelope with the pole pieces and armature stem extended outwardly beyond the confines of the envelope and in which electrical flux is utilized to bias the armature into selective contact with one or the other of the contact faces of the pole pieces within the envelope, the improvement comprising electrical operating coils positioned on opposite sides of the envelope and within the side projection outline of the envelope, low reluctance material extending through ends of said coils and magnetically coupled to the exposed armature stem, said low reluctance material having portions extended from the other ends of said coils and in closely spaced and magnetically coupled relation to said pole pieces, the electrical connections of the coil and the magnetic arrangement being such that the electrical coils impose one polarity on the armature, when said coils are energized, and the opposite polarity on said pole pieces.
