Abstract: Tine assemblies (100a, 100b, 104) are secured by a single bolt (126) extending diametrically through each tine (120) located in a cavity (112) of a tine plate (110). An outer tine assembly (104) is connected to a sleeve (116) rotatably mounted on independently rotatable shafts (102) to which inner tine assemblies (100a, 100b) are connected. A tine cover (50) removably closes an opening (40) in the top plate (28) and in which weights (70) are removably received over the tine assemblies (100a, 100b, 104). Transport wheels (134) are moveable by pivoting a stop plate (140) to position an upper pivot axis (150a) of an abutment bar (150) ahead of or behind the stop axis (142) and lower pivot axis (150b). A stop (146) positioned on the stop plate (140) without the use of tools adjusts the depth of the tine assemblies (100a, 100b, 104).

Abstract: A rehabilitation device for simulating walking movement, including a base assembly mounting a foot support member in elevated relation to a walking surface on which the base assembly is reposed. The base assembly features a slotted platform member which is interdigitatingly matable with a slotted anterior portion of the foot support member. The foot support member is pivotally translatable about a transverse axis between its anterior and posterior portions, such that the anterior end of the foot support member can swing below or above the platform member of the base assembly. The supported foot thus is able to "follow" the unsupported foot when the latter is moved forwardly or backwardly, and mimic natural walking movements. A corresponding rehabilitative method is disclosed. The invention is usefully employed to rehabilitate persons afflicted with stroke, muscular atrophy, etc.

Abstract: A device is disclosed for holding a membrane filter with use of a porous metal disk support for a membrane. In the method of assembly the metal disk and membrane are sealed to a fusible enclosure by heat formed in the metal disk by induction heating. Such heat seals the metal disk and also seals the surface of the membrane to the fusible surrounding enclosure. The device is particularly useful in filtering particulate matter from intravenous solutions administered into the circulatory system of a human.

Abstract: Livestock and poultry excreta can be treated to destroy pathogenic bacteria therein and to eliminate offensive odors by contacting the excreta with from 0.10 to 3% by weight of the waste matter of a liquid aldehyde, preferably formaldehyde in aqueous solution.

Abstract: An elongated cylindrical body is provided and includes a diametrically reduced sharpened tubular needle extension on one end for opposing and piercing the puncturable seal of a medicament vial. The other end of the cylindrical body includes a slightly inwardly tapering diametrically enlarged counterbore communicated at its inner end with the interior of the tubular needle extension.

Abstract: A cap is provided for telescoping over the puncturable seal of a medicament vial and particularly a unit dose medicament vial. The cap includes a center outwardly projecting tubular extension including outer end circumferentially spaced inwardly projecting abutments. A needle structure including a generally cylindrical body is slidingly received within the tubular extension of the cap and includes a diametrically reduced sharpened tubular needle extension on its inner end opposing and for piercing the puncturable seal of the associated vial upon movement of the needle structure inwardly of the tubular extension or mounting portion of the cap.

Abstract: The safety cap of the present invention is for use with a medicament vial having a puncturable seal. The cap includes a cylindrical extension provided with a shape-retentive but slightly expandable cylindrical body slidable therein having a diametrically reduced sharpened tubular needle extension on its inner end for piercing the seal. The body includes first and second portions of slightly different diameters, with the portion of smaller diameter outermost, and an inwardly tapering center portion, thus defining two shoulders for cooperating with an inwardly projecting lip on the outer end of the cylindrical extension to resiliently resist inward movement of the body and to prevent outward withdrawal of the body after it has been pressed inwardly to puncture the seal.
