Abstract: Specifically, the present invention relates to processes for preparing delayed action galenic forms. The process is characterized in that the application solutions of excipients, coatings and active constituents are adjusted to a desired pH. The independence of the rate of dissolution of a controlled release or sustained action oral pharmaceutical form is increased by admixing a pH adjusting agent with every application solution of medicament, excipeint or coating, throughout the course of formulation of the pharmaceutical form.

Abstract: A device for the unidirectional transdermal administration of a drug in an ointment, cream or jelly-like carrier comprising a laminar applicator adapted to receive a predetermined quantity of the drug on a skin-contacting surface thereof, the applicator including a drug-impervious lamina such as a layer of aluminum foil, overlying said skin-contacting surface, such that in use a unidirectional transfer of the drug from the carrier to the skin surface is ensured. The device is especially suitable for the transdermal administration of nitroglycerin, clonidine, methadone and scopolamine or any drug that is skin-permeable. The drug receiving surface may be embossed, pressed, or stamped to define one or more mini-recesses or receptacles for receiving the drug to be administered.

Abstract: The invention involves positioning the working end of a vertical pump below the surface elevation of the fluid, enclosing a space around the pump with a structure extending below the surface and having a submerged opening to the main reservoir, and drawing a vacuum in the enclosed space in order to raise the surface elevation in the enclosed chamber in order to maintain a minimum working depth for the vertical pump that will prevent air entrainment by vortexing during periods of low fluid levels outside the chamber.

Abstract: A compact animal feeder having a tubular housing with paired feed access openings spaced side-by-side in the sidewall. The feed access openings are located upwardly on the sidewall so that a rounded bottom portion of the tubular sidewall forms a trough which tends to hold feed centrally in a chamber formed within the housing. A feed delivery tube enters from above through another opening in the housing and extends downwardly between each pair of feed access openings to a point above the rounded trough bottom. An adjustable gap permits a given amount of feed to pile up below the feed supply tube. The feed pile automatically stops further flow. Multiple animal feeding is possible from a location at the side of a pen. Oppositely paired feed access openings can be used to permit installation between pens.

Abstract: An improved manure spreader and process for unloading and spreading utilizes a powered flexible reversible movable floor which moves with the load towards the thrower so that the load is uniformly conveyed without relative movement between the load and the flexible movable floor and with an automatic stop system to stop movement of the floor when an upright wall portion of the movable floor reaches the area of the thrower with the automatic system also stopping the upright portion of the movable floor at its maximum extension for the loading mode after it has been reversed.
