Abstract: A process for preparing a transdermal drug delivery device includes preparing a polymer matrix by homogenizing about 7 weight % sodium alginate with about 3.5 weight % glycerol for about 5 minutes, mixing with about 0.5 weight % nicotine in about 89 weight % distilled water, casting the mixture over a backing material and drying overnight, and spraying with an about 5 weight % solution of calcium ions to cross-link. A control release membrane is prepared by homogenizing about 3.1 weight % of sodium alginate with about 3.6 weight % of glycerol for about 5 minutes, mixing with about 93.3 weight % of distilled water, casting the mixture over a backing material and drying overnight, and spraying with an about 5 weight % solution of calcium ions to cross-link. And, the drug delivery device is assembled by cutting a circle of the polymer matrix and a circle of the control release membrane and assembling them in sequence on a piece of backing material.
Abstract: This invention relates to a gas generating agent pack of an air bag inflation gas generator that is used to form a combustion chamber in the air bag inflation gas generator and aims to steeply improve reliability for ignition capacity as compared with the prior art by a simple structure. And, this invention consists of accommodating a plurality of gas generating agents with a through hole formed at the center in the stacked state in the axial direction within a longitudinal cylindrical pack, sealing one end of the cylindrical pack with a cap, inserting a projection for accommodating an igniter formed to project at the center of the cap into the through hole of the gas generating agent disposed at one end of the cylindrical pack, and disposing an ignition agent next to the end face of the projection of the cap within the through hole of the gas generating agent disposed at one end of the cylindrical pack.
Abstract: A basketball goal for use with a basketball backboard having a front surface has a rigid annular rim which is normally disposed horizontally during play and a rigid metal plate fixed to the rigid annular rim and extending rearwardly therefrom in coplanar relationship thereto. The goal includes a mounting bracket having at least a back wall and a top wall mounted on the front surface of the backboard by the backwall and pivotally connected to the rigid metal plate. The rigid metal plate is pivotally connected to the bracket to thereby permit the rigid metal plate and rigid annular rim fixed thereto to pivot in relation to the backboard. The releasable latching mechanism is rollably interconnected to the rigid metal plate and to the mounting bracket and permits tilting of the rigid annular rim from the normally horizontal play position thereof only when force of at least a certain preselected amount is placed upon the rigid annular rim.
Abstract: A transdermal system employing a basic active component-permeable, pressure sensitive adhesive polymer material, particularly for use with basic active components for use in transdermal administration of systemically or topically acting medicaments constituted by such active components. The adhesive polymer is a homopolymer or copolymer produced using basic monomers preferably on an acrylate base. A process for production of the polymer material comprises mixing monomers suitable for the production of an adhesive by polymerization with basic monomers which can be polymerized and copolymerizing the mixture. The adhesive composition is in particular useful with basic active components in salt form and in which the therapeutically active agent is a Lewis base.

Abstract: A plastic working method for making a holed metal part. A holed blank with a through hole is placed at the center in a die member which has a die and a container continuing to the die. The die is pushed toward a punch, inserting into the through hole a first portion of a mandrel which has cross sections with at least two different cross-sectional areas. The blank is compressed by a counter punch fitting with the container and a punch pressing the die end face of the die member toward the counter punch to cause the blank plasticly to flow into a space formed between the die hole of the die and the first portion of the mandrel and while applying a compressive force to the blank by the punch and the counter punch, pulling out the first portion of the mandrel out of the blank through hole while inserting a further portion of the mandrel into the through hole so as plastically to flow the blank into a gap between the first portion of the mandrel and the through hole.
Abstract: In a gas generating agent pack for an air bag inflation gas generator of this invention, a plurality of gas generating agents with a through hole formed at the center is accommodated in the axial direction in the stacked state within a longitudinal cylindrical pack whose both ends are tightly closed, and an energizing means for energizing the gas generating agents toward the end of the cylindrical pack is disposed within the cylindrical pack, so that the plurality of gas generating agents accommodated into the cylindrical pack can be tightly contacted securely to one another.
Abstract: A screen printing apparatus has simultaneously movable multiple print heads made movable by a single fluid cylinder. The apparatus also has multiple printing platens, and structure for indexing and simultaneously registering the multiple platens into printing position, as well as combined flood bar/squeegee ink applicators which are capable of simultaneously shifting of operational positions, and provide a high quality printed image on the goods printed thereby.
Abstract: A hammer of the type having an impact tool driven by pressurized fluid has a hammer body portion with a closed rearward end and an open forward end and a piston longitudinally movably housed within the hammer body portion for striking a tool mounted at the open forward end of the hammer body portion, to thereby impact an object with the tool. The hammer has a fluid valve housed within the closed rearward end of the hammer body portion rearwardly of the piston and in communication with a source of high pressure fluid for driving the piston. The fluid valve has a valve body portion defining an interior chamber and a continuous exterior side wall, and a longitudinal opening in communication with the interior chamber. The valve body has a first body portion and second body portion which is identical to the first body portion and positioned longitudinally in relation thereto within the closed rearward end of the hammer body portion.
Abstract: The invention relates to a primary pack for surface-stabilized bandaging materials having a carrier layer and a skin-side contact surface having pressure sensitive adhesive areas and which prior to the use of the bandaging material is protected by a removable covering layer, and an at least one-layer supporting film detachably applied to the skin-remote surface of the carrier layer and which can be removed from the applied bandaging material, the supporting film forming part of the pack protecting the bandaging material.
