Abstract: A hypodermic syringe system for injecting a predetermined dosage of therapeutic fluid into body tissue of a living patient. A sealed capsule contains the fluid to be injected. A double ended hypodermic needle includes a first sharpened end for piercing engagement with the body tissue and a second sharpened end opposite therefrom for piercing engagement with the capsule. The capsule is disposed between the end of a plunger which is slidably engaged within a barrel member supporting the needle and the end wall of the barrel member. Advancement of the plunger moves the capsule into piercing engagement with the second sharpened end of the needle, collapsing the capsule and discharging the therapeutic fluid through the needle and into the body tissue. A safety syringe with a retractable needle is disclosed. The system is also provided with an aspirating capability to inform the user whether or not a blood vessel has been pierced by the needle.

Abstract: An improved hypodermic syringe includes a needle retraction feature permitting the needle to be fully retracted into the cylindrical cavity of the syringe barrel following the injection of medicine into a patient. The needle is held on the distal end of the barrel by means of an attachment hub, which includes an internal abutment surface to prevent outward movement of the needle. Inward movement of the needle is prevented by an expandable restriction of a distal barrel opening, extending between the cylindrical cavity and the distal end of the barrel. The needle is part of a subassembly including a flange held between this internal abutment surface and this expandable restriction. The distal end of the plunger is fitted with a needle extractor, which moves into the distal barrel opening as the plunger is pushed fully into the cylindrical cavity.

Abstract: Male animals may be chemically castrated by injecting both testes and/or both spermatic cords with a castratingly effective amount of a protease enzyme such as a chymopapain-rich enzyme preparation.

Abstract: A method for the preparation of ultra low-fat cheese products. The product is prepared by plasticizing a composition containing the desired low level of lipid, preferably butterfat; an amount of protein, preferably dairy protein, sufficient to emulsify the lipid; and from about 50% to about 70% moisture. The plasticization is achieved by subjecting the composition to the high speed cutting action of a razor sharp bladed food comminuter or to ultrasonic treatment to rupture the fat globules of the lipid and to reduce the particle size of the protein matrix, for a period of time sufficient to plasticize the composition. The physical changes which take place in the protein micelles and fat globules results in protein/fat interaction forming a stable self-emulsified product without the addition of chemical stabilizers or emulsifiers.

Abstract: A disposable syringe for dispensing a metered dosage of a material includes a plunger rod which is axially movable within a syringe barrel for dispensing the material. The plunger rod includes a rail section located axially outside the syringe barrel, and a slidable stop member is secured to the rail section for adjusting the volume of material to be dispensed. The adjustable stop member includes a knife edge for embedding into a surface of the rail section of the plunger rod to lock the stop member in a desired position.

Abstract: A method for the preparation of a low-fat butter or margarine product for use as a table spread. The product is prepared by plasticizing a composition containing from about 15% to about 50% lipid, preferably butter fat; an amount of protein, preferably dairy protein, sufficient to emulsify the lipid but insufficient to stabilize the lipid against plasticization; and from about 40% to about 60% moisture. Salt, butter coloring and butter flavoring are preferably also included. The plasticization is achieved by subjecting the composition to the high speed cutting action of a sharp bladed food comminuter for a period of time sufficient to plasticize the composition. The product is a smooth plastic spreadable butter substitute containing nutritious protein, which is low in fat and does not require the need for emulsifiers and stabilizers. The product is spreadable immediately after removal from refrigeration, as well as at normal room temperatures.

Abstract: There is provided a method for the control of oral mal odors by rinsing the oral cavity for a total time period of at least one minute per day and with each rinse time being at least 0.5 minute with an oral rinse consisting essentially of an aqueous solution of 0.01% to 1% of a water-soluble potassium fluoride and/or sodium fluoride. The method also, concurrently, controls calculus formation.

Abstract: There is provided a two-compartment container. A lower mixing compartment has a closure which seals that compartment, and the upper end of an upper compartment is disposed in the closure and communicates through the closure to an aperture therein. A lower slideable seal in the lower end of the upper compartment effects a seal between the two compartments. That seal is exitable from the upper compartment by means of a digitally powered linking means projecting from the aperture, whereby the contents of the upper compartment are dispersed into the contents of the lower compartment. The lower seal quickly exits from the upper compartment and the contents impinge upon the lower seal and deflect therefrom to more uniformly disperse into the lower compartment.

Abstract: An adjustable dosage syringe is provided wherein the syringe plunger has sets of multiple closely spaced indentations along the length of the plunger, and a dosage selection ring disposed around the plunger. The inside circumference of the dosage selection ring has protuberances which are registerable with and receivable in one of the indentations of the sets of indentations so that when one protuberance is received in an indentation of the first set of indentations, the other protuberance is also received in an indentation in the second set of indentations. Channels are disposed along the length of the plunger for simultaneously and slidably receiving the protuberances so that the ring is longitudinally slidable along the length of the plunger.

Abstract: There is provided a disposable enema syringe for self-application and/or one hand use wherein the syringe is of the type having a barrel with a transversely extending flange at least partially disposed about the open end thereof, a movable piston disposed within the bore of the barrel and a plunger having one end connected to the piston and the other end extending out of the bore and terminating in a digit receiving pressure pad. The pressure pad is at a distance from the flange such that the syringe may be controllably grasped by one hand between the thumb and a finger around the barrel and next to the flange and the index or second finger on the pressure pad. The syringe has a soft and flexible cannula which is sufficiently long that it may be inserted into the rectum and past the sphincter muscles and sufficiently short that it may be inserted into the rectum with only one hand.

Abstract: There is provided an antimicrobial animal teat dip tincture composition and method of use thereof. The ingredients of the composition are: a microbicide, water-soluble, lower alkanol, water and lower-alkanol-soluble film-forming polymer, and a water soluble emollient. Mastitis is controlled by applying the composition to the teats of animals, and allowing the composition to dry on the teats to form a film of the polymer containing the emollient. The lower alkanol gives a very rapid and effective kill of microbes on the teats while the emollient will remain on the teats in the polymer film and prevent chapping and drying of the teats. Preferably, the composition also contains a further microbicide which remains in the polymer film and provides a residual long-term mastitis protection. Quaternary ammonia microbicide compounds provide superior results in this regard, as opposed to other conventional microbicides. The ingredients provide a freeze resistant solution.

Abstract: There is provided a packaged disposable animal waste container which has in packaged combination an open-top moisture resistance receptacle of such size that an animal may stand in the receptacle and with side walls sufficiently low that the animal may step into the receptacle, but sufficiently high that normal animal pawing will not displace animal waste and the like therefrom. Packaged within the receptacle are a plurality of nested trays each having dimensions so that the trays closely fit within the receptacle side walls. The trays also have side walls sufficiently high for containing an effective layer of animal waste absorbent. The package has a removal retainer means for retaining the nested trays in the receptacle during shipping and handling. The nested trays are removed from the receptacle and serially placed in the receptacle for use by the animal. A soiled tray is removed and replaced by a clean tray.

Abstract: There is provided a package for dispensing a plurality of flowable materials. A first container is composed of a closed bottom, associated side walls and an open top. A second container is composed of an apertured bottom, associated side walls and an open top. The second container can be slid into the first container and it will remain in essentially sliding contact with the inside of the side walls of the first container as it traverses the depth of the first container. A unitary conduit is in fluid-tight communication with the aperture of the bottom of the second container and a first dispensing orifice disposed near the top of the side walls of the second container. When the second container slides into the first container, flowable material in the first container is expressed through the dispensing orifice via the conduit.

Abstract: A syringe for dispensing medicaments or other materials includes a hollow syringe body having a discharge end portion and an open opposite end portion through which a plunger is slidably received. The plunger has a first end portion located within the syringe body and includes an integral seal forming a seal between the plunger and the interior of the syringe body. A removable length adjusting member is threadably engaged on the plunged outside of the syringe body to variably limit operating travel of the plunger in the syringe body, thereby to control the amount of material in the syringe body expelled therefrom upon depression of the plunger into the syringe body.

Abstract: A dispensing container for combining and then dispensing two discrete materials includes a first open top container element for containing the first material, e.g. a fluid and a second container element having closed upper and lower ends for containing the other of the two materials, e.g. a powder or a liquid. The second container element is dimensioned to be telescopically received with its lower end within the open topped container element. A valve is provided in the lower end of the second container element for normally keeping the materials in the container elements separate but permitting fluid in the first container element to flow into the second container element upon depression of the second container element, thereby causing materials in the two containers to combine. The upper end of the second container element may be provided with a removable cover so that the mixed materials can be dispensed.
