Abstract: A radiation protection system around a patient on an x-ray table includes a radiation protection wall with an opening around the x-ray table, a radiation screen over the patient, and a flexible interface joining the cubicle and the x-ray table. The wall shields medical personnel in an operating region from most radiation output by an x-ray emitter. The radiation screen is attached to the x-ray table such that it can be retracted to the foot of the x-ray table and extended over the patient such that it is interposed between the patient and the medical personnel. The interface has flexible joints attached to the wall and a flexible radiation-resistant skirt that joins the wall to the screen and covers the opening in the wall. An access port may be formed in the screen, and a shielding cloak can cover the access port to surround medical instruments that are threaded through the port and inserted into the patient.

Abstract: A business form with label areas removable therefrom and an improved process for producing a label. The process includes feeding a sheet of paper into a paper processing apparatus, having a roll of transfer adhesive stock with a first and second liner with adhesive therebetween, means for separating the second liner from the transfer adhesive stock, cutting a strip of transfer adhesive stock from the roll of transfer adhesive stock and adhering the transfer adhesive stock to the sheet of paper whereby it can be cut to form a label peelable from the transfer adhesive stock. In addition, a transfer adhesive stock comprising a first and second liner with a layer of pressure sensitive adhesive between one side of the first liner and one side of the second liner, each liner having a different adhesive affinity whereby one liner may be removed from the other liner and adhesive.

Abstract: A plate brake tester for testing the adequacy of the brakes of a vehicle includes first and second pairs of weight bearing plates, each sized to receive at least one wheel/tire assembly of a vehicle as a vehicle is driven over the plates. The first pair of plates are spaced from the second pair a predetermined distance along a predetermined direction of travel, which predetermined distance is substantially greater than the length of each plate as measured along the predetermined direction of travel. Sensors sense, for each plate, the brake force applied by a brake associated with the wheel/tire assembly passing over that plate and the dynamic weight of the wheel/tire assembly on each plate during braking. Control circuitry determines from the brake force and the directly sensed dynamic weight the adequacy of the brakes of the vehicle under test. Preferably, the first and second pairs of plates are approximately 30 feet apart along a test lane, and each plate is approximately 36" in length and 48" in width.

Abstract: A mattress system includes a first section of foam material forming the head section of a mattress, a second section of foam material forming the central section of the mattress, and a third section of foam material forming the foot section of the mattress. The second section of foam material has a load responsive characteristic different from the load responsive characteristic of the first and third sections. The central section may be replaced by an inflatable air chamber.

Abstract: A laryngeal mask of the type used to facilitate lung ventilation and the insertion of endo-tracheal tubes or related medical instruments through a patient's laryngeal opening as used during general anesthesia, intensive care, or critical patient care. The mask includes an inflatable positioning shield formed to fit within a patient's oropharynx and seal around the circumference of the laryngeal opening, the shield having an inflatable annular toroid peripheral portion, a contoured rear portion, and a recessed front. The mask also includes a flexible respiratory tube having an proximal end lumen, a gently curved tubular body of sufficient size to permit passage of endo-tracheal tubes, and related medical instruments, and a distal end passing through and secured to the proximal edge of the annular toroid peripheral portion.

Abstract: A device for the cessation of the blood flow in an extremity comprising a plurality of chambers encircling the extremity in a sequential arrangement. Each chamber being able to individually apply or release pressure to the extremity. The device has a monitor for determining the pressure applied to the extremity. The device further having a mechanism for continuously cycling the chambers.
