Abstract: A method for preserving the temperature integrity of cryogenically preserved biological samples is presented, involving initiating a countdown sequence upon removal of a sample from a controlled portable or bulk storage environment, requiring operator action to terminate the countdown on restoration of the sample to a controlled environment. Audible and visual warnings are provided to an operator prior to attainment of a critical temperature, beyond which damage may accrue to the sample. A portable device facilitating execution of the method is described.

Abstract: A storage unit includes a housing with a storage chamber, a carrier disposed inside the chamber for supporting a plurality of specimens in a predetermined array, and an access port on the housing for enabling access to the chamber for insertion and retrieval of specimens from the carrier. The access port includes an opening in the housing and a plug member removably located in the opening. The carrier is provided with a seat for receiving the plug member during an access operation, so that the plug member is located in the chamber during the access operation. A drive is operatively connected to the carrier for moving the carrier in the chamber to juxtapose different specimens to the access port. An insertion and removal mechanism is coupled to the housing for alternately inserting and removing specimens from the chamber via the access port during the access operation.

Abstract: A method of degassing utilizing a degassing faucet having a first portion which includes a liquid inlet with a first cross-sectional area and a liquid outlet with a second cross-sectional area smaller than the first cross-sectional area, the liquid outlet being disposed adjacent a conduit portion having a cross-sectional area larger than the second cross-sectional area and the degassing faucet having a second portion with an impact surface.

Abstract: To provide ultrasonic cleaning of inanimate objects, ultrasonic waves in a frequency range of between 15 kilohertz and 10 megahertz are applied to water in a tank with a power density between 15 and 7,000 watts per square centimeter. Asymmetric power waves are applied to avoid instability leading to transient cavitation. To provide ultrasonic treatment of animals, ultrasonic waves in a frequency range of between 15 kilohertz and 500 kilohertz are applied to water in a tub with a power density between 0.1 and 5 watts per square centimeter. The equipment is able to apply ultrasonic waves with at least two power densities in the vicinity of the portion of the animal with one of said power densities being more than 15 watts per square meter for sterilizing the water before the patient enters the tub and the other being less than 15 watts per square meter.

Abstract: To permit comfortable bathing by an ambulatory patient without the assistance of another person, a bathing system includes a movable portion and a stationary portion, with a movable portion including a tub that pivots between a bathing position and an entering-and-exiting position. The stationary portion includes a seat for the patient which remains stationary as the tub moves, a drive mechanism for the bath tub and a source of warm sparging air and warm circulating air. When the tub is in the entering-and-exiting position, the chair is positioned so the patient can enter it easily but recessed within the tub walls so that he is partly encompassed by the tub and the warm air is able to circulate around the patient. The pivot point and size of the tub permit the tub to fit within an alcove. Controls are mounted so that the patient may manipulate the tub from position to position and control the warm air and water.

Abstract: The specification discloses apparatus which constitutes a portable bath-tub which is vertically adjustable to facilitate patient handling and transfer, bathing, draining after use, and cleaning. The apparatus includes a tub mounted within a frame, a platform upon which the patient can be placed in a supine posture, means for lowering the platform into the tub and raising it again, means for raising and lowering the frame and therefor the tub from a lower preset height to a greater height and wheel means on said frame to permit transfer from place to place.

Abstract: The specification discloses a wheeled multi functional vehicle or chair for therapeutic and rehabilitative use by invalids and others having muscular and neurological disability. The vehicle is characterized by a frame on which is supported independently adjustable elements including a seat, back support, an activity table, foot support, and associated limb positioning and restraining elements. Also disclosed is a unique locking apparatus for adjustable positioning and attachment of the various elements.This invention is directed to an apparatus or device for the treatment and normalization of individuals both infant and adult, who are physically handicapped by reason of muscular or neorological trauma. More particularly, it is directed to a multi-positional vehicle of the walker-perambulator type capable of functions essential to the care, normalization and treatment of patients suffering from cerebral palsy and similar conditions.
