    Abstract: Semi-hard magnetic materials exhibiting an excellent square hysteresis loop are prepared by the following steps. An alloy material consisting essentially, by weight, of 73-93% Co, 1-5%Nb and the balance Fe is subjected to process annealing at not lower than 900.degree. C and cold working at a reduction of area of not less than 75% and then is subjected to any combination treatment involving one or more stress relief annealings at a temperature in the range 500.degree.-700.degree. C for a short period of time such that no intermetallic compound precipitates in said alloy followed by cooling to the ambient temperature, and one or more ageing treatments of said cooled material at a temperature in the range 600.degree.-900.degree. C for a considerably longer time such that an intermetallic compound does precipitate in said alloy.

    Abstract: A reed switch construction is described embodying magnetic metal reeds and an improved glass envelope. The envelope is drawn from an infrared absorbing glass having a steep viscosity curve which permits forming a seal between the metal reeds and the glass envelope with infrared heating at a temperature sufficiently low to avoid damaging the reeds.

    Abstract: A relay switch spring composed of an elongated flat strip which has a core made of an electrically conductive material surrounded by a sheath of material of a lower conductivity than the core material. The strip has a free end to which a contact is connected so that the contact engages both the core and sheath material.

    Abstract: A reed for use in a reed-type switch comprising a body of magnetic material having a contacting surface essentially made up of a precious metal with some of the body material diffused therein, and an interface layer of an alloy of the precious metal and the body material between the body of magnetic material and the precious metal layer. The magnetic material is a glasscompatible nickel-iron alloy containing from about 0.125 to about 0.250 manganese by weight percent and having a resistivity not greater than about 225 ohms per circular mil foot.
