Abstract: A system for simultaneously rupturing and carrying away a breakable foil seal and packing from a medicine vial or other container which incorporates a string attached to the foil seal with one end exterior of the foil seal and the other attached to the packing. The exterior end serves as a pull tab or can be attached to another item which serves the same purpose. When pulled, the string first ruptures the foil seal, then carries it away along with the packing. The pull tab may be length of string, additional foil layers of the seal or the vial lid. The system is designed to facilitate access to the contents of the vial by individuals lacking dexterity due to age, illness or amputation.

Abstract: A security display rack for articles comprising an elongated outer channel having first and second legs, a web interconnecting the legs, and a plurality of notches extending through the legs and opening at the outer edges of the legs. An inner channel having first and second legs and a web interconnecting the legs of the inner channel are received in the outer channel with the legs of the inner channel extending from the web of the inner channel toward the web of the outer channel. A plurality of pins is carried by the web of the inner channel and is adapted to engage one of the articles with such article projecting through the grooves in the outer channel. A locking member is mounted on the channel for opening and closing the ends of the grooves.

Abstract: A security display rack comprising an elongated support member appropriately elevated above a supporting surface and an elongated locking member. The support member has an elongated surface and a plurality of grooves extending through the support member and opening at the elongated surface. Each of these grooves is adapted to have at least a portion of an article inserted therein with the grooves spacing the articles along the support member. The locking member is mounted for movement so that it can open and at least partially close the open ends of the grooves. The locking member has a closed position in which it lies along the elongated surface of the support member and at least partially closes the open ends of the grooves. In the closed position, the articles inserted into the grooves either cannot be withdrawn from the support member of their withdrawal is impeded. The locking member can be locked in the closed position.

Abstract: A method and apparatus for transmitting hydrogen gas from one point to another wherein the hydrogen gas is first purified to remove deleterious oxygen, carbon dioxide and any other contaminate. The gas may be compressed to raise that pressure to a preselected level. The pressurized hydrogen gas is introduced into the inlet of a pipeline which is at least partially filled with activated metallic hydride wherein at least a portion of the hydrogen gas is absorbed by the metallic hydrides and is transported by migration through the metallic hydrides from the inlet towards the outlet end of the pipeline, and withdrawing the hydrogen gas from the pipeline outlet end, at least a portion of the hydrogen gas delivered at the outlet end as a consequence of desorption from the metallic hydride.

Abstract: Electronic control apparatus for controlling the administration of a plurality of separate fluids independently and consecutively, includes electrical circuitry connected with a plurality of valve operators to operate valves in a plurality of sets to control flow therethrough.

Abstract: An electronically controlled, gravity-feed, intravenous infusion set in which a length of intravenous tubing is connected with a drip chamber to convey a fluid to be administered intravenously, the improvement comprising a normally closed internal valve in said set operable to prevent flow of fluid through the set and operated to open position to enable passage of a drop of fluid through the set, and an electrically controlled actuator operatively associated with the valve to operate the valve to its open position at a predetermined frequency of operation and to hold the valve open until a drop forms and falls to thus determine the drip rate of fluid through the set, said internal valve thus enabling control of flow of fluid through the set without necessitating crimping or other deformation of the set and thereby resulting in dependable and accurate control of the flow rate of the fluid to be administered intravenously.

Abstract: An electronically controlled intravenous infusion set of the gravity feed type having a flow path including a drip chamber and an internal valve for regulating flow through the set. Electromagnetic valve operating structure, positioned outside the IV set, controls the internal valve in response to an electronic control system. The electronic control system serves to open the valve to allow a drop to fall, and includes a control circuit. The control circuit includes an optical drop detector, associated with but positioned outside the drip chamber, which senses the falling drop and signals the control circuit to close the valve. The control circuit also includes a variable frequency clock and associated digital selectors for affording an attendant the ability to precisely select a desired drip rate. An alarm system, operating on digital principles, senses high drop rate or low drop rate conditions and, in response thereto, puts the control system into an alarm condition.

Abstract: A point-of-sale terminal system including one or more keyboard terminals and associated cash drawers in communication with a control chassis having a micro-computer, a printer and power supply. Each keyboard terminal has manually operable keys for designating the various items for sale and associated display devices which, under the guidance of the computer, display the number of each item ordered. Function keys are provided for instructing the computer to total the sales price of each order with automatic tax calculation. Provision is made for the temporary storage of one or more orders with a recall feature that redisplays the order. Numeral keys are provided at the keyboard to give an alternate method of incrementing and decrementing item quantities and to provide means for effecting price and tax changes. Order changes may be effected at any time prior to the total sales price calculation that enters the sales price and item quantities into the computer's permanent memory.
