Abstract:
A rotatable scale arrangement for strip chart recorders and the like for providing access to recorder writing elements from the front of the instrument. A mechanism is provided for simultaneously rotating each of a plurality of elongated flat strips, adapted to include scale markings, from a position facing the front of the recorder to a position normal thereto, wherein a substantially wider separation is provided between the strips for removal or insertion of the writing elements.
Abstract:
A square core is mounted in a housing with opposite legs only clamped to the core, one leg clamped by a cantilever spring which allows the core to expand in its plane under the influence of temperature. The legs are essentially single lamina, each of which is made up of a pair of Mumetal strips spotwelded together. The other legs have energizing, sensing and feedback coils thereabout, which coils are wholly supported by and within the housing.
Abstract:
A LINK CONSISTING ESSENTIALLY OF TWO IDENTICAL ELONGATED SPRING LAMINAE, EACH HAVING A HOLE THERETHROUGH, AND SANDWICHED TOGETHER ALONG THEIR LENGTHS, OVERLAPPING EACH OTHER AND SECURED TOGETHER AT THEIR INTERMEDIATE PORTIONS, SO THAT SAID LINK IS LONGER THAN EITHER LAMINA. EACH LAMINA HAS ITS SAID HOLE IN ITS OVERLAPPED END, SUCH HOLE OPENING OVER THE SURFACE OF THE CORRESPONDING OVERLAPPING LAMINA END. CORRESPONDING LAMINAE ENDS ARE MANUALLY FORCIBLY SPREAD APART TO RECEIVE BETWEEN THEM ANOTHER LINK HAVING A BALL OR THE LIKE WHICH PROTRUDES INTO
THE CORRESPONDING HOLE. THE LATTER LINK IS SANDWICHED BETWEEN THE SAID LAMINAE WHEN THE LAMINAE ENDS ARE RELEASED FROM MANUAL FORCE SPREADING THEM APART.
