Abstract: The efficiency of membrane separation is enhanced in a hyperfiltration process by scooping off controlled amounts of the boundary layer at desired points along the flow path where useful concentrations have been achieved avoiding the necessity of bringing the entire flow up to desired concentration. The use of porous stainless steel supports with membranes formed therein in situ after fabrication from the pipe sections in a single pass configuration is especially advantageous with scoop apparatus spaced along the length of the stainless supports.

Abstract: A tension control mechanism for cloth delivered from the loom and the like to a cloth roll carried by take-up mechanism positioned in front of the loom is illustrated wherein a sensing device engages the cloth coming from the loom under relatively light tension for driving motor control means responsive to movement of the sensor imparted thereto by variation in cloth tension.

Abstract: A method and apparatus for artificially implanting hair in human skin tissue is disclosed wherein a strand of hair is folded upon itself to define a pair of strands joined together by a U-shaped bend at which an enlarged anchor element is provided to be implanted in the skin with the strand of hair exposed above the surface. The apparatus includes a plurality of needles carried in a side-by-side relationship on a base member each needle having an interior bore in which the anchor element is held with the hair strands held by a hair clamp on the enterior of the needle. The needle is inserted into the skin and the anchor is dislodged therefrom whereupon withdrawal of the needle leaves the anchor implanted with the hair strands exposed above the skin surface.

Abstract: A hip joint mechanism for adapting a leg prosthesis to a body adapter is disclosed which includes a hip hinge assembly having a hinge base and a hinge gate which pivot to accommodate pivoting of the leg prosthesis during sitting and a swivel assembly having a lock coupling providing locked and free rotational and longitudinal movement of the leg prosthesis. Means are provided for adjusting the hip joint mechanism to place the leg prosthesis in proper body and weight support alignment.

Abstract: An article retarding device for use with a grid set of a case loading machine for breaking the fall of articles as they are dropped through the grid set into a case. The grid set includes a trip-bar assembly which is shifted to drop the articles. Positioned below the trip-bar assembly are a plurality of pivotally supported downwardly extending fingers carried in the form of a matrix which guide the articles into the case as they are being loaded. A camming mechanism selectively forces the fingers of respective passages to the center of the passages for breaking the fall of articles into the case. Means is provided for retracting the camming mechanism to a second position so that the articles can be gently loaded into the case.

Abstract: Apparatus for positioning and protecting a patient in bed is disclosed as including a protective device for cushioning a side frame of a hospital bed and the like which includes an elongated strip having a slot accommodating placement over the side frame and a thickened portion serving as a cushion. A body positioner formed from a block of polyurethane foam having resilient characteristics capable of deformation is disclosed having a length substantially greater than its width whereby the block may be placed on a base surface to provide a continuous support for the major portion of a patient's body while laying in bed. In a preferred embodiment, a core of the positioning block is cut out and may be removed and utilized as the protective side frame cushion while the body positioner block may be utilized to position the patient as desired.

Abstract: A method and device for cleaning a rotor in an open-end spinning machine. While the rotor is running at a speed less than the normal r.p.m. a first flow of cleaning air is directed to a collecting groove of the rotor and a second flow of cleaning air is simultaneously directed to the periphery of the spinning rotor at an angle different from the first flow of air. In one embodiment, at least one of the flows of air is directed in a pulsating manner. The flows or streams of air are fed through ducts provided in an extension of a cover which extends within the rotor or is supplied to the rotor by means of a movable housing.

Abstract: Apparatus is disclosed for properly supporting and positioning a patient's arm and shoulder when placed in a prone position on an operating table for laminectomy surgical procedures and the like after correct positioning of the spine is accomplished. The apparatus includes a resilient arm cradle having a trough which supports the arm distally from the shoulders to adjacent the patient's wrist which flexes to support the arm naturally bent and in which the weight of the arm is supported over a greater surface area in a manner which is particularly advantageous in preventing pressure points on the elbow. The apparatus further includes an axilla cuff which fits under the axilla and has an exterior contour which interfaces with the shape of the trough of the arm cradle in such a manner that a desired rotation of the shoulder is maintained so as to preclude brachial plexus damage.

Abstract: The invention relates to a beater roll comprising a body and a saw tooth wire helically fitted to the surface of the body wherein the helical convolutions are in spaced relation and wherein a sealant is employed to seal repetitive gaps or spaces between the base of the wire and the smooth cylindrical surface of the beater roll, such repetitive spaces or gaps being caused by placing the set necessary to accommodate wire clothing to the cylindrical surface of a roll as used in open end spinning.

Abstract: A compound bow having a handle and flexing limbs extending outwardly from the handle. A bracket is carried adjacent a medial portion of the handle and a pair of arms are pivotally secured thereto. The arms diverge rearwardly from the bracket. A string engaging member is carried adjacent the outer ends of each of the arms. A pair of pulleys are carried adjacent each remote end of the limbs. A bow string has opposed ends thereof attached to a respective inner end of a respective arm. The string extends around the pulleys on the ends of the limbs and the string engaging members so that when a notching portion of the string is drawn for shooting an arrow, the pivotal arms are pivoted from an open extended position to a partially closed position providing a uniform draw of the string when drawing the string from a released position to a fully drawn position. A pair of eccentric cams are carried adjacent the arms over which respective opposed end portions of the string extends.
