Abstract: An ambulatory cardiac monitoring system (10) to event record and monitor ECG signals (20) from a patient (12) for a predetermined time interval. The ambulatory cardiac monitoring system (10) includes a recorder system (18) which is carried by the patient (12). The recorder system (10) is coupled to the patient through leads (16) and electrodes (14) positionally located contiguous to the patient (12). The recorder system (18) includes an analog pre-processor (32), a first microcomputer (34) coupled in a feedback manner to analog pre-processor (32), and a cassette recorder (38). The analog pre-processor (32) has incorporated both automatic gain control and conditioning circuitry that normalizes and filters the basic ECG signal (20). The analog pre-processor (32) produces a plurality of extraction signals which are input to microcomputer (34).

Abstract: A fork lift attachment system is adapted to be mounted to a standard fork lift truck utilized for vertically lifting and lowering a container in a reversible manner. A modified container is utilized in conjunction with the fork lift attachment system where the container includes a pair of transversely displaced channel members securely fixed to opposing transverse side panels of the container. The attachment system includes a releasable mounting mechanism for insertion within the channel members of the modified container for mounting the container to the fork lift attachment system. A rotative displacement mechanism allows for the container to be rotated about a first axis line extending in a direction substantially normal to a vertical displacement direction subsequent to the container being mounted on the fork lift attachment system.

Abstract: Disclosed is a ground fault detection system utilizing a distributed array of current rate of rise sensors located at and coupled to the various power substations of an underground trolley system. Threshold detectors and logic circuits measure and compare the rate of rise of current at the various substations with preselected threshold values to distinguish ground faults from normal load transients due primarily to locomotive start-up.

Abstract: An animal enclosure system comprising an enclosure and a modular assembly of enclosures. Each enclosure is adapted so that environmental conditions may be easily and economically changed and conformed to the particular animal in that enclosure. A selection of different levels for the animal and access means for the animal between levels is provided. An adjustable drain and overflow assembly is provided, adapted to permit easy, selective, accurate and reliable adjustment of the water level in the enclosure and to prevent inundation, even if there is a continuous influx of water. Wet-dry environment balance is carefully controllable.

Abstract: A load bearing pendant system of the type commonly used in conjunction with an overhead conveyor system. The disclosed pendant system is adjustable to operate in either of two distinct modes. A first mode of operation provides for continuous rotation of a work piece being linearly displaced along a conveyor line. A second mode of operation provides for indexed rotation at various predetermined spacial intervals along the line. Conversion from operation in either mode to the other is accomplished by threaded securement or removal, thereby avoiding the otherwise necessary capital investment in two separate sets of pendant systems directed to each mode. The load bearing pendant system includes a hanger assembly upon which objects are releasably mounted. The hanger assembly is linearly driven in a predetermined direction along the conveyor system. A hanger drive mechanism which is connected to both the hanger assembly and the conveyor system either rotates or provides for indexing of the hanger assembly.

Abstract: An improved thermometer which is case hardened and includes a total enclosure composed of a pair of first and second layer members covering the stem portion and the bulb portion respectively of the thermometer. A substantially transparent plastic material layer member covers the stem portion of the improved thermometer and has an index of refraction which is sufficiently high to allow a user to visually interpret the location of an internally contained heat expandable substance in relation to indicia formed on the stem portion. Additionally, the first layer member is irradiated from a source of soft Beta rays for hardening the outer surface layer of the first layer member. The bulb section of the improved thermometer is enclosed by a second thermally conductive layer member. Both the first and second layer members are joined to form a total enclosure for the thermometer throughout the extended length of both the bulb and stem portions.

Abstract: A dialyzer and a dialysis system particularly adapted to fast dialysis and avoidance of contamination or spillage. Adjustable upper and lower clamp units are provided on a central shaft. Means are provided to securely mount a plurality of dialysis bags around the entire periphery of the clamping units and to provide adequate bath circulation through the relatively confined core volume. The individual dialysis bag may be accurately filled or emptied while in a fully installed position on the dialyzer. The circulating pump is a pair of openings in the bottom clamp unit. The top of each bag is always open to receive a syringe needle. The rotating motor is isolated from the bath.

Abstract: Method of covering a thermometer which includes forming a total enclosure composed of a pair of coatings covering the stem portion and the bulb portion of the thermometer. A substantially transparent plastic material covering the stem portion of the improved thermometer has an index of refraction which is sufficiently high to allow a user to visually interpret the location of an internally contained heat expandable substance in relation to indicia formed on the stem portion. The bulb section of the improved thermometer is enclosed by a thermally conductive layer. Both layers are joined to form a total enclosure for the thermometer throughout the extended length of both the bulb and the stem portions. Additionally, an increased amount of substantially transparent plastic material is added to the terminal end of the stem portion of the improved thermometer in order to provide a cushioning effect under dynamic loads when the thermometer inadvertently falls to an external surface.

Abstract: A mirror cleaning device which provides for a generally closed container having cleaning and defogging liquid maintained therein. The cleaning device includes a cup member having a cover. A liquid dispensing securement device consisting of a pair of tubular elements secured each to the other and intersecting in a substantially perpendicular manner extends through and is secured to the cover. A pair of cotton rolls are inserted within each of the tubular members into contiguous contact with each other. One of the cotton rolls is vertically directed and extends from the first tubular member, partially immersed within the cleaning liquid maintained within the cup. The second tubular member is generally horizontally directed and is partially open in contour to allow exposure of the cotton roll inserted therein. Capillary or wicking action permits the continuous flow of fluid from the liquid within the cup to the horizontally directed cotton roll where a mirror to be cleaned may be wiped across a bottom surface.
