  • Patent number: 5799846
    Abstract: A portable holder for holding containers for feeding a product from the container to the human body such as intravenous feeding or colon flushing in which the holder is strapped to the upper torso of the human body. Being strapped to the body, it enables the person to be mobile without having to push along a cart or a stand. It also gives the person an unlimited range since the container goes with the person.

  • Patent number: 5236420
    Abstract: A resilient material pressurizing plunger for syringes or like containers in which the plunger construction is such that on the initial insertion into the syringe by a first inserting member, the plunger is distortable thus allowing the gas pressure generated by the plunger insertion to escape. The plunger is also capable of pressurizing the chamber when further insertion occurs by use of a second insertion member which prevents the distortion.

  • Patent number: 5186323
    Abstract: A device capable of joining, holding, and opening a pair of sealed containers with contents. Each container is attachable to one of a pair of container opening parts movable with respect to each other. While in the attaching position the containers are maintained in sealed condition and are held in this position with respect to each other. The containers can remain in this position indefinitely or the containers can be moved to a different position from the attaching position. During this movement between the two positions, each of the pair of container opening parts opens a container and forms a passageway almost equal to the area of the seals for the contents of the containers to flow into either container to mix the contents of both containers.

  • Patent number: 5054433
    Abstract: A resilient material belt provided with openings substantially across the width of the belt. The openings having one portion close to one edge of the belt and the opposite portion of the opening located a distance in toward the center of the belt from the opposite edge of the belt. The opening is located in this manner to retain the belt in normal configuration up to a given tension on the belt. At the given tension the material between the edge of the belt and the opening on the side where it is closest to the edge breaks, allowing the belt to elongate by the distortion of the openings in the belt.

  • Patent number: 5038718
    Abstract: A resilient material flea and tick belt wherein the stretching strength of the resilient material of the belt is reduced in a given portion of the belt by providing slits or cut outs in a definite pattern. In the specific application as in animal flea and tick collars, the belt can stretch a distance that will prevent the animal from strangling if it is caught on a foreign object such as a branch of a tree.

  • Patent number: 4929230
    Abstract: A syringe for hypodermic injection wherein multiple pistons seal various number of chambers. One piston provides the basic operating force to dispell the contents from a chamber or successive chambers and another piston or other pistons forming a chamber or additional chambers permitting release of the chamber contents or successive chamber contents and a syringe holder for holding, using and disposing of the syringe minimizing potential of accidental sticking by the needle of the syringe.

  • Patent number: 4334536
    Abstract: A hypodermic syringe needle assembly for prefilled syringes in which the means for attaching the needle assembly to a syringe, the cover for the portion of the needle used for injecting and the cover for the portion of the needle used to activate the syringe is a unitized structure. This structure is breakable at a specific break point when the prefilled syringe is activated for use and breakable at another specific break point to expose the injection needle.

  • Patent number: 4305526
    Abstract: An upwardly opening receiver for receiving the lower open end of a box containing articles to be dispensed, an article carrier shiftable transversely through a lower region of the receiver, and a pusher on the carrier for pushing engagement with the lowermost article upon carrier movement to dispense the article exteriorly of the receiver.

  • Patent number: 4226376
    Abstract: A device for breaking various size ampules at the ampule neck, which is the most convenient break point for extracting the fluid from the ampule. The ampule breaker comprises a formed structure having a wedge surface which contacts the ampule at the neck and sides adjacent to the wedge which are contoured to contact the extremities of the appendage to be broken off from the ampule. The contoured sides extend beyond the point where the extremities contact so that no matter which size ampule is inserted into the breaker, a mechanical advantage is provided to help break the ampule appendage. A staggered set of cover plates are used to retain the ampule appendage during and after breaking.

  • Patent number: 4041763
    Abstract: Material is inspected, transferred or sampled at one or more preselected positions in a rectangular array of columns and rows according to a predetermined program. A transfer tube, probe, or other element, referred to generally as a sampling element, is transported along predetermined rows of the array from the first to the last column position. When the sampling element reaches a preselected position at which material is to be inspected or transferred, the sampling element is actuated. For example, the sampling element is transported from a non-sampling position to a sampling position at which material can be inspected in or transferred to or from a container at the preselected position. The sampling element is then transported to the next position in the row at which material is to be inspected or transferred. After the sampling element reaches the last column of the last row, it is transported back to the first column of the array.
