The invention disclosed concerns a method of selecting a standard glove size. The method includes the steps of selecting a pair of two dimensional measurements which are correlated to hand volume, dividing a population of hand volumes into a predetermined number of approximately equally populated subgroup ranges, plotting two dimensional chart areas for each subgroup based upon intersections of the selected two dimensional measurements with reference to a predetermined point on the chart, and assigning one of the standard sizes to each chart area. The method further includes the steps of placing a hand on the predetermined point and plotting the intersection of the pair of two dimensional measurements for the hand to select the proper standard glove size. The chart can include areas for both left and right hands and the predetermined point can abut the web space between the middle and index fingers on the hand.
摘要:
Ground water containing ferrous compounds is first treated with aluminum sulfate before aeration followed by lime addition after aeration to produce an iron-aluminum sludge possessing an oxidative capacity. Portions of the sludge are recycled back to utilize the oxidative capacity of the sludge. Chlorine is added after the oxidative capacity of the sludge has been utilized. An improved oxidation and removal of iron is obtained, yielding a treated water low in iron content with decreased requirements for chlorine.

An improved surgical instrument cartridge is described. The cartridge comprises a plurality of wound closure elements. Each element has a crown and two opposite side legs. The distal end of each leg of an element contacts the crown of the adjacent preceding element. Two opposite grooves (in the cartridge) contain at least each end of each crown and the proximal end of each leg. The cartridge is attached to a surgical instrument. To activate the plurality of closure elements, a spring acts only on the proximal element. The improvement comprises the distal ends of the legs of each element being in an essentially converging relationship. The plurality of elements are thus self-aligning in the grooves. The wound closure element can be a staple.

A measuring device for ascertaining the perimeter of a cross-section of a body comprising an integral tape and slide guide. Laterally extending tabs at one end of the tape are foldable over a portion of the tape bent back upon the tab bearing end to form the slide guide. An aperture in the tab bearing end cooperates with indicia on the tape to display the perimeter of the tape loop extending from the slide guide.
