Abstract: A surgical instrument includes an anvil and an elongate channel. The elongate channel includes a plurality of first electrical contacts and a plurality of electrical connectors comprising a plurality of second electrical contacts, wherein the electrical connectors are spring-biased such that a gap is maintained between the first electrical contacts and the second electrical contacts. The surgical instrument further includes a staple cartridge releasably attachable to the elongate channel, wherein the staple cartridge has a cartridge body comprising a plurality of staple cavities, a plurality of staples deployable from the staple cavities into the tissue, and a plurality of third electrical contacts, wherein the attachment of the staple cartridge to the elongate channel moves the electrical connectors causing the second electrical contacts to bridge the gap and become electrically coupled to the first electrical contacts.

Abstract: An orthodontic device for providing a removable anchorage for elastic traction between upper and lower molars. A smaller-diameter wire having a free posterior end and a larger-diameter wire having a posterior end lying anteriorly to the posterior end of the smaller-diameter wire are connected together well anterior of their posterior ends. At least one wire has stop means thereon spaced from its posterior end, while a short hook depends from at least one wire adjacent to its anterior end. In installation the device is used in conjuction with a first metal band suitable for attachment around an upper molar and having two buccal tubes, namely a larger-diameter tube and a smaller-diameter tube in which are inserted the two wires. A second metal band encircles a lower molar corresponding to the upper molar and has band anchor means on its buccal side. An elastic band joins the anchor means to the hook.

Abstract: A kitchen utensil for attachment to the handle of strainers to enable their partial support by a table surface. The device includes mechanism for attachment by sliding action to the ordinary handle of the strainer and a pivoted support rod, which can be swung down from a position substantially parallel to the strainer handle to one substantially perpendicular to it, or any intermediate angle thereby to enable the utensil to be supported by the table, as well as by the container in which the strainer rests.

Abstract: A tea strainer for use in straining tea while it is poured into a teacup, which may be sitting in a saucer. A bowl-like sieve member, provided with projections for engaging the lip of the cup, also has a handle which is made in two parts connected together by a hinge. The hinge is so located that the outer portion of the handle can swing downwardly into contact with the table on which the cup rests. The inner handle portion is sufficiently long so that it lies normally beyond the diameter of the saucer when the cup is sitting in the saucer. The hinge is stiff enough so that it ordinarily must be manually and purposely moved from one position to another. When held in the hand, the tea strainer functions as a normal tea strainer with a stiff handle, but when placed in the cup and the handle moved about the hinge and put in contact with the table, it becomes self-supporting.
