Abstract: This invention relates to a foaming enzyme composition and delivery method useful for the cleaning and maintenance of moist conditions of the surfaces of soiled instruments, utensils and other devices prior to final cleaning and/or sterilization. The aqueous composition preferably consists of a combination of: (1) an enzyme cleaning solution, (2) foam-building ingredients; (3) a corrosion inhibitor; and (4) an antimicrobial agent. The composition may be dispensed from a pump spray as a stable foam which covers the surfaces of the instrument to be cleaned, and remains on the surface of the instrument for at least 30 minutes, and preferably until the instruments are finally cleaned and sterilized. The composition and delivery method of the present invention is particularly useful for the pre-cleaning of complex medical instruments such as endoscopes.

Abstract: An aqueous acidic disinfecting and sterilizing composition for medical instruments, which may include brass, copper, aluminum, stainless steel, plastic and ceramic components. The composition contains hydrogen peroxide, peracetic acid, a corrosion inhibitor system, a surfactant and a stabilizer. These compositions have in use stability and are effective as a disinfectant and/or sterilant either at room or when heated. For other applications, surfactants, sequestering agents and stabilizers may be optional.

Abstract: A locking device in the shape of a unitary body formed from a bio-degradable material which includes an element with at least one free end formed integral with said body. The severable element is designed to engage and secure a container lock mechanism when the container is in a closed position, whereby the free end of the element is capable of being mechanically or adhesively secured to said unitary body to form a seal, with said device being designed to fracture upon opening of the container lock mechanism thereby providing visible evidence of the lock mechanism being opened.

Abstract: An improved open end construction for jacks which provides for tabs which extend at right angles to the side surfaces of the channel members so as to allow pivot pins to be received in the open ends after which the tabs are bent so that they lie in the plane of the side surfaces of the channel members so as to lock the pivot pin in the ends of the channel assembly. Also, partial flanges can be formed about the openings in the ends of the channel members so as to provide bearing surfaces for the pivot pins.

Abstract: A jack handle which limits the torque that can be applied to a jack so as to prevent overload and injury. The jack handle has a reduced cross-sectional portion between the handle and the jack engaging portion so that the handle will break off at the reduced cross-sectional portion, thus, preventing overloading of the jack. A portion of the handle which does not break off is provided with a jack engaging portion so that the broken portion of the jack can be removed and the second jack engaging portion can be inserted into the jack to lower it.

Abstract: An improved drive unit for a jack mechanism which is formed from an inexpensive stamping and it can be attached to the control shaft of a jack by staking, welding or other matter and which can be bent into a shape which has an opening to receive a flatted handle for operating the jack and which also has manual extensions which can be used to manually lower and raise the jack.

Abstract: An improved lift cap for a jack which comprises a two-piece lift cap that fit together with tab and slot arrangements and which allow the overall mass of the jack to be substantially reduced by allowing the width of the base and channels to be reduced. The improved lift cap has a raised portion which serves as a stop to align the jack and which also provides additional support to lift a vehicle which is being lifted by the jack.

Abstract: A scissors jack which has improved formed gear teeth which allow a jack to be retracted to a very low profile so that it can be placed under the vehicles. The teeth of the lower pivot arms are formed so as to extend one direction and the teeth of the upper pivot arms are formed so as to extend in the opposite direction from the teeth of the lower pivot arms so that when the jack is in the down position, the gear teeth on the upper and lower pivot arms can pass each other and thus allow the jack to have a very low contour.

Abstract: A control device for use with an electrical appliance. The device comprises a handpiece having at least one exhaust port which is connected to positive fluid pressure source. Blocking of the exhaust port will operate an appropriate switch means for controlling the electrical appliance.

Abstract: An improved planetary gear box for a heavy duty truck jack which includes a planetary gear box that provides high torque and in-line input and output shafts and a high gear ratio and a compact package which does not require many precision machine parts. The invention uses parts formed by stamping rather than machining and uses a floating ring gear which can move relative to the housing, thus, allowing a stamped ring gear to be utilized. Floating planetary gears are used by providing slotted carriers whic allow the planet gears to float which eliminates concentric problems with the planet gears and the carrier assembly. The invention allows the use of a stamped housing and the rear carrier of the planet gears is staked to the drive pilot of the jack screw. The invention results in an improved and less expensive jack than utilized in the prior art.

Abstract: A sterility indicator which comprises means defining an elongated outer compartment having liquid impermeable and substantially non-gas absorptive walls, said compartment having a closed end and a first opening at a distal end thereof and a second opening which is gas transmissive and bacteria-impermeable disposed at least partially around the perimeter of said outer compartment and located near said first opening, with a predetermined number of viable microorganisms suitable for monitoring steam sterilization being confined within said outer compartment adjacent said second opening, and a predetermined number of viable microorganisms suitable for monitoring gas sterilization being confined within said outer compartment away from said second opening and opposite said distal end; a closure member normally closing said first opening and movable to a second position to also close said second opening; and an inner compartment containing a nutrient medium disposed within said outer compartment with said nutrient m

Abstract: The present invention is directed to sterility indicators of the self-contained biological type and provides a device that assures direct impingement of the sterilant onto the microproorganisms. In this manner, the sterilant exposure conditions experienced by the test organisms reflects the exposure conditions to which the articles in the sterilizer are subjected. The device of the invention provides that the microorganisms are not directly contiguous with the ampule containing the aqueous nutrient medium.

Abstract: A disposable sterilizer mechanical air removal test pack comprising an outer container in the form of a box having a definite shape and being formed of a relatively air and steam permeable material coated with a form-stabilizing layer of a relatively air and steam impermeable material, and a body of relatively air and steam permeable material enclosed in the box. An indicator means is arranged in the body of material for indicating when contact with steam has taken place. The box includes a plurality of closure flaps which provide interruptions which control and direct the flow of steam into and air out of the interior of the body of material with the flow of steam and air occurring predominantly in a lateral direction through the body of material.

Abstract: The invention relates to a cabinet in which food packages, such as prepared school lunch packages, can be heated prior to serving, and maintained at a desired temperature before and during serving. The cabinet comprises an upwardly opening well closed by removable lids, a housing connected to and surrounding the well on the sides and bottom thereof and being spaced from the well so as to form a substantially enclosed air circulation chamber adjacent the sides and bottom, and a plurality of louvers in the side walls defining air inlets and outlets between the well and air chamber. Electrical heating elements are mounted within the air chamber directly below the bottom of the well so that heat generated thereby will radiate upwardly thereby heating the well bottom and, to a lesser extent, the well side walls. A thermally conductive baffle plate is disposed within the air chamber beneath the bottom of the well and functions as a heat sink to disperse and even out the radiant heat.
