| 161 | Scanner with reed relays | US26403872 | 1972-06-19 | US3812439A | 1974-05-21 | PARMENTER G |
| Electrical switching apparatus such as a scanner comprises a plurality of reed relays, each of which has an operating coil, and at least one reed contact unit which is mounted outside the coil, to reduce thermal E.M.F. generation. The reed contact units are mounted on a first printed circuit board, and control respective analogue signals passing through the printed circuit tracks of this first board, while the coils are mounted on, and respectively energised via the printed circuit tracks of, a second printed circuit board parallel to the first board. In this way, interference between the scanned analogue signals and the relay energising signals is reduced.

| 162 | Reed switching assembly of deformable material | US3786384D | 1972-03-20 | US3786384A | 1974-01-15 | JONES J |
| An electrical device and method of making same is disclosed wherein a rigid base member is provided for supporting electrical conductive elements and a thermal plastic member heat sealed thereto. A reed relay is described with blades mounted on a rigid ceramic base and hermetically sealed into a switching chamber by a thermal plastic cover member sealed at the periphery to the base member as by heating with a peripheral metal strip or sonic bonding. Localized deformation of the enclosure sets the gap of the contact blade. A blade is positioned in a slanted notch to spring bias the blade against another and the switching blade can be provided with a perforation filled with a previous metal contact material.

| 163 | Sealed contact relay assembly | US3763449D | 1972-11-13 | US3763449A | 1973-10-02 | KIMBALL D |
| A sealed contact relay assembly includes a resilient ferromagnetic reed, and a nonmagnetic reed having relatively high electrical conductivity, which extend through opposite ends of a sealed nonmagnetic envelope and which have slightly overlapped inner contact portions within the envelope. A ferromagnetic member is mounted outside the envelope such that energization of a coil produces magnetic forces of appropriate polarity in the resilient ferromagnetic reed and the ferromagnetic member so as to cause the inner contact portion of the ferromagnetic reed to disengage from, or engage with, the inner contact portion of the nonmagnetic reed, depending upon their initial relative positions. The sealed envelope is positioned in a spool on which the coil is wound, and the opposite ends of the spool are filled with nonmagnetic encapsulating material to anchor the envelope and projecting portions of the reeds in fixed positions.

| A reed type electromagnetic circuit switch designed mainly for operation in power circuits of switchgear installations, as well as in automatic control and electric drive systems where the power handled may amount to tens of thousands of voltamperes and rated currents may reach tens and hundreds of amperes; the current circuit of the reed switch is made up of solid current leads, a flexible shunt, and contact tips, manufactured from materials possessing high electrical conductivity. The arrangement includes an armature consisting of a ferromagnetic reed member and thinner ferromagnetic strips and provides for high electromagnetic pull and contact pressure, while a shield and a loop increase the reliability of the reed-to-reed insulation in the off-position and make it possible to develop most reliable and wear resistant contactors. An electromagnet is arranged to attract the armature, and has poles which are introduced into a sealed casing, while the coil of the electromagnet is disposed outside the casing.

| 165 | Windings for operating efficiently contacts of reeds with constricted areas | US3678423D | 1970-08-31 | US3678423A | 1972-07-18 | ROVNYAK RICHARD M |
| The length of an operating winding is related to the positions of constricted areas that result incidentally from formations of a blade from round wire at one end of each reed. Since sensitivity of a winding for operating the reeds is found to decrease rapidly as the winding becomes longer than the distance between the constricted areas, a sectional winding for operating the reeds is centered over the contacts between the constricted areas, and hold windings, effective after the reluctance of the path has been decreased by closure of the contacts, are positioned in an adjacent winding space.

| A relay switching apparatus of particular utility in telephone switching installations is described. The apparatus includes a plurality of magnetically actuatable switching arrangements encapsulated in a protective cartridge. The magnetic circuits of each switching arrangement includes first and second polestrips and an armature having its movable end extended into an air-gap formed by the two polestrips. The operating parts and the supports for the operating parts are clamped in a self-gripping manner onto at least one separator piece which determines the size of the air-gap, and these parts are so secured to one another as to form a mechanical unity. The switching arrangements are divided into at least two construction groups with the construction groups being positioned one over the other, and the switching arrangements are placed in each construction group such that pairs are formed with the switching arrangements in the other construction group. The switching arrangements are clamped between the above described supports, and a case connects the supports in such a manner as to form therewith a protective cartridge enclosing all of the switching arrangements. The construction groups formed a switching arrangement compressed against the sides of the walls of the cartridge by pressure strips. Each pair of switching arrangements have a common electrical energizing circuit which includes a winding and a soft iron yoke with the shoulders of the yoke extending outside of the cartridge and being magnetically coupled to the second pole pieces in the cartridge.

| 168 | Sealed contact relay | US3605049D | 1970-01-12 | US3605049A | 1971-09-14 | WIELEBSKI WAYNE H |
| A sealed contact relay has a plurality of sealed switches each enclosed in a modular cartridge. The relay structure has a Ushaped yoke made of magnetic material with two coils, one surrounding each leg of the yoke. A set of spaced magnetic flux fingers extend from the end of each leg of the yoke and in the same general direction. The cartridges are removably mounted between the spaced flux fingers of each set and bridge across the magnetic gap between the two sets of flux fingers. An indicator cap is attached to the top of the relay having a pivotally mounted indicator arm which swings away from a spring-biased position when the coils are energized. In another embodiment, a manual actuator is provided and has a magnet that can be moved into magnetic contact with the flux fingers to cause flux to flow in either direction through them.
