Apparatus for carrying out the above method is also disclosed comprising, in combination, a first and a second wall means defining a first and a second surface, each placed in contact with animal tissue to be measured and respectively cooperating with first and second sensor means so that the temperatures of said surfaces can be compared and simultaneously processed with the measurement of the indicator concentration performed by a separate measuring means also in contact with the tissue, so that the perfusion efficiency factor can be determined.

Abstract: Method of and apparatus for preparing weft supply in a magazine for weft insertion in shuttleless looms, particularly looms with pneumatic or hydraulic weft insertion. The yarn path is prolonged by the action of an air flow in the magazine, into which the weft is continuously fed upon being withdrawn from a supply bobbin. The weft is withdrawn from the magazine in weft inserting intervals in a length sufficient for one pick. The inside of the magazine is constituted to produce a helical air flow which directs the fed weft into a spatial spiral or helox, from which the inserting length is axially withdrawn.

Abstract: Vesicular recording materials are described which include a sensitized layer comprising a polyeric vehicle for the sensitizing agent which is an acrylonitrile/substituted or unsubstituted styrene copolymer with at least 55 mole % of acrylonitrile and preferably less than 85 mole %. The copolymer is usually homogeneous and preferably derived from acrylonitrile and the styrene comonomer along and most preferably contains from 65 to 82 mole % of acrylonitrile. The copolymer is softenable on heating to permit the gas released by the sensitizing agent in the light struck areas to form light-scattering or reflecting vesicles therein.A surfactant in an amount of at least 1% by weight, based on the weight of the copolymer, is essential to vesiculation and anionic surfactants are especially effective in providing a wide tonal range and good speed rating, amounts up to 20% by weight being preferred.

Abstract: Two layers or cloth or other material are quilted together by embroidery stitching to outline on the material multiple rows of repetitive glove body shapes. The multiple pre-stitched glove bodies thus formed integrally with the quilted material layers are separated from the material by die cutting around the margins of the glove bodies slightly outside of the stitching lines which delineate them in the quilted material. Cuffs are attached to the separated pre-stitched glove bodies by conventional procedures, followed by turning the gloves inside-out and inspecting the finished gloves. Manual labor commonly involved in sewing glove body pieces together and closing glove bodies is eliminated.

Abstract: Prosthesis suitable for replacing or supplementing damaged ligaments or tendons are prepared from polyethylene terephthalate strips by treating such strips with a shrinking agent under restraint in the longitudinal direction. The treatment reduces substantially the extensibility of the fabric in the longitudinal direction. Stiffness can be imparted to the strips by forming the strips into tubes which may have longitudinally-extending ridges thereon and heat-setting same.

Abstract: A system for controlling the operation of an electrically powered prosthetic appliance which replaces an amputee's missing limb. The method employed consists of conducting electromyographic (EMG) signals from the stump of the missing limb and processing the signals so as to reduce them to a near minimum number of linear time series model parameters effective to differentiate between each of the several functions performed by the missing limb from each other function thereof. A filter array carried by the amputee subsequently employs the identified parameters such that each individual filter of the array is tuned according to a set of parameters related to one of the limb functions considered. The myoelectric (EMG or ME) signal as obtained at a surface electrode worn by the amputee is fed to each filter of the above array of filters, and the outputs of these various filters are used for a decision by the system as to which limb function should be actuated.
