Abstract: Provided is, among other things, an attachment apparatus that includes an attachment base, a magnet attached to a first side of the attachment base and a clip structure extending from a second side of the attachment base, the second side being opposite the first side. The clip structure, in turn, includes first and second arms which can be resiliently spread apart in order to receive an item and then released in order to close around the item.

Abstract: Extra coagulant is added to the cuff portion of the former by a spray nozzle located between the coagulant and latex dipping tanks. A former is placed into a coagulant. After removal from the coagulant, additional coagulant to the cuff portion of the former by any conventional means, such as a spray nozzle. The higher concentration of coagulant at the cuff portion results in a thicker latex thickness at the cuff portion and counteracts the reduced dwell time of the cuff in the latex dipping tank as compared to the fingertip portion of the former. The thickness of the cuff portion can be controlled by altering the concentration of the coagulant applied by the spray nozzle.

Abstract: The invention is the manipulation of the zinc oxide content and sulfur content of nitrile butadiene rubbers and selected vulcanization conditions that can be achieved economically with common production facilities. The manipulation of these components affects the relaxation property of gloves formed by this material. Produced are gloves that have a relaxation property, higher than 50%, and a low modulus (approximately 3 Mpa). The glove maintains decent ultimate tensile strength (>20 Mpa) and elongation (>500%). The glove is produced by a vulcanization process, which lasts from 5 to 60 minutes at temperatures ranging from 300° F. to 400° F. The tensile strength and elongation are well above the ASTM requirements for medical gloves. The current ASTM requirements are ASTM D412-92. Thanks to sufficient vulcanization, the films produced provide satisfactory protection from viral penetration. The tearing strength is also better because of the lower modulus.

Abstract: An apparatus for measuring the penetration depth of a blunt object before failure of a film sample, such as a glove. Failure occurs when a film sample secured to a column ruptures from the force applied by a stylus. The penetration depth of the blunt object is equal to the distance traveled by the stylus under the method of the invention. With the measurement of the penetration depth and the force applied by the stylus, a quantitative measurement of the rupture strength of the film sample is obtained.

Abstract: The cable puller uses a compound handle to create great leverage in order to generate a large pulling force with a minimal amount of force applied by the operator. The pulling force can be used for heavy lifting applications. The cable puller could be used to hoist motors, shafts, gears, automobile engines, construction material, machinery and other heavy objects. The cable puller could also be used in the demolition of building structures, the erection of buildings and towers, straightening collision damage, opening railroad car doors, securing tent structures, stretching fence and wire, and tightening conveyor belts. In one embodiment, the handle creates a lever ratio of 65:1. In this instance, 8,000 lbs. can be lifted with an exertion of 123 lbs. of force by the operator. The compound handle is formed by a driven member that engages and rotates the ratchet wheel. A cable is taken up by the wheel in order to move objects. The driven member is connected to a driving member by a connection member.

Abstract: A system for optimising the cycling conditions used to control a polymerase chain reaction assigns membership values for denaturation, annealing and extension events in order to determine the relative contribution of each event during the reaction, and using genetic algorithms to determine the optimum times required to complete each event.

Abstract: A new formulation for producing nitrile gloves has been developed. The resulting glove shows following outstanding characteristics: stress at six minutes greater than 50% of its initial value; ultimate tensile strength and elongation well above ASTM requirements; and much lower modulus than almost all the nitrile gloves currently commercially available. The unique formulation is zinc oxide free and is vulcanized from 5 to 60 minutes at temperatures ranging from 300° F to 400° F.

Abstract: A ribbon microphone having magnets positioned adjacent north and south pole pieces. The magnets are of uniform thickness along their lengths, and do not taper. The pole pieces are substantially the same width as the magnets. An offset ribbon is disposed in an air gap between the pole pieces. The offset ribbon is not centered in the air gap, but rather is offset from a center line which bisects the magnets and pole pieces. The offset ribbon is located closer to the front of the microphone than the back of the microphone. The flux area is uniform and corresponds to the area of the air gap between the pole pieces.

Abstract: A mailing package comprises a package body having a first section, a second section, and a third section, the first section connected to the second section by a first foldable joint;the second section is connected to a first end section through a second foldable joint and a second end section through a third foldable joint and having a plurality of end slits cut therethrough disposed near the end flaps, a first and second guide receiver slit, and a main locking flap receiver slit; andthe third section connected through a fourth foldable joint to the second section, and to a first locking end flap, a second locking end flap, and a main locking flap having a main locking tab and a first and second guide tab;the sections joined such that when the second flap is folded over the third flap the plurality of end slits are presented to the first and second locking end flaps, the first and second guide tabs are received in the first and second guide receiver slits and the main locking receiver slit is presented to the

Abstract: Emergency and other personnel needing gloves can retrieve them easily for donning using a glove and hand protectant dispenser. The dispenser includes a backboard having at least one detachable glove dispenser member disposed proximate a first edge of the backboard; and at least one detachable hand protectant disposer proximate a second edge of the backboard.

Abstract: A two paste glass ionomer type dental cement system, with both pastes being, preferably, of similar consistency. The first paste represents primarily a suspension of an inert filler in a water solution of polyacrylic acid, or its copolymers with other ethylenically unsaturated acids, having molecular weight of 25,000 to 100,000 and, optionally, various additives, such as filler suspending agents, coloring agents, agents influencing working/setting time (retardants or accelerators), Theological agents, pH modifiers, etc. The other paste represents primarily a particulate glass flux containing silicon and aluminum oxides, calcium fluoride and, optionally, other inorganic salts, including aluminum phosphate, and sodium, barium and aluminum fluorides, suspended in a liquid medium consisting primarily of a water solution of a hydrophilic acrylic monomer or polymer. In order to achieve a desirable consistency, organic or inorganic thickening agents may be added in suitable quantities.

Abstract: A chewable softgel formulation to deliver water soluble vitamins and supplements to improve dissolution time and availability. The formulation contains components design for the elimination and prevention of dental caries, bad breath, gingivitis and also inner ear infections.

Abstract: Adhesive coatings designed primarily for protecting, restoring, repairing, or modifying surfaces of, objects made of polymeric materials. Such coatings are particularly useful in application over worn, cracked, discolored, or otherwise defective objects made of polyacrylic, polystyrene, and polycarbonate resins. The adhesives of this invention are basically comprised of blends containing a substantial concentration of tetrahydrofurfuryl methacrylate and/or furfuryl methacrylate.

Abstract: A health-care glove constituted of thin elastic rubber-like material and having a thumb member at one side edge and a pinkie member at the opposite side edge. The glove has visual indicia for indicating to the user, the location of the thumb member so as to enable him to initially pick up the glove and easily apply it onto his hand, with the thumb member and pinkie member in the proper relative positions.
