Abstract: An immunoadjuvant capable of producing secondary antibody responses as great as 50 to 60% of those obtained using Freund's complete adjuvant (FCA) which responses decline at a slow rate while not showing the disadvantages associated with FCA. The immunoadjuvant comprises an immunoadjuvant oil such as a mineral oil, squalene or squalane and a polycationic polyelectrolyte immunoadjuvant such as DEAE-Dextran or polyethyleneimine. The immunoadjuvant preferably comprises an emulsion having the oil in one phase and an aqueous solution of the polycationic polyelectrolyte in the other phases. Such immunoadjuvants are used with antigens, such as conjugates of hormones, e.g. luteinizing hormone releasing hormone, and an immunogenic protein.

Abstract: A cardioversion/defibrillation system employing a dual biphasic and multi-electrode discharge technique for effectively defibrillating the heart by creating a voltage gradient throughout substantially all of the heart which is above a critical voltage gradient while delivering a minimum energy shock. Effective cardioversion/defibrillation is accomplished by delivering two shocks to the heart. The first shock is at an energy level lower than that typically necessary to cardiovert/defibrillate the heart alone, and is applied between a first pair of cardioversion/defibrillation electrodes. The second shock is at an energy less than the first shock and is applied between a second pair of electrodes to shock the area of the myocardium provided with an inadequate voltage gradient from the first shock. The voltage gradient in the low gradient areas is boosted above the minimum gradient necessary to defibrillate.

The raw feed material exhibits a specific surface area of 0.05 up to 500 m.sup.2 /g (BET), preferentially 5.0 up to 50 m.sup.

Abstract: Apparatus for severing sheet material which includes pairs of upper and lower jaws which may be moved towards each other to grip and tension sheet material disposed between the jaws. An elongated severing blade is arranged between one of the pairs of jaws, the latter normally being biased to a position where they conceal the blade but being movable against the bias when engaged by the other jaws to expose the severing blade for severing of the tensioned sheet material.

Abstract: A method for classifying cardiac arrhythmias by examining the atrial and ventricular activity of the heart. The atrial contraction rate and ventricular contraction rate are compared with each other when the ventricular rate exceeds a preset value. When the atrial rate exceeds the ventricular rate, the regularity of the atrial rate, ventricular rate, and time interval between atrial contraction and ventricular contraction are determined. Regularity is determined by computing the standard deviation of a variable and comparing the standard deviation with a predetermined fractional value of the variable. A therapy routine is provided depending on the classification of a detected arrhythmia and the level of the ventricular contraction rate.

Abstract: The invention concerns an ion exchange process and system, particularly for the regeneration step following a softening or desalination of aqueous solutions. The regenerant solution is fed in an upward stream through the ion exchanger in a direction opposite to the charging direction, as a sequence of intermittent pulse intervals consisting of pulse flow followed by a period of no flow. During the pulse flow, there is limited hydrodynamic lifting of the ion exchange resin beds in layers, followed by subsequent sedimentation during the pause period, without mixing of the layers.

The surfaces forming the upper and lower edges are provided with channels (13, 13') which allow modules placed one above the other to be coupled by inserts fitted into the channels. The protuberances (10') on opposite parallel surfaces have aligned bores (11) in which rods (11') are insertable to allow several modules to be coupled together side by side and edge to edge.

Abstract: A food-grade oxygen scavenger for removing oxygen from foods and beverages in containers is prepared by immobilizing dried yeast containing at least 92% dry matter in a solid material such as wax or paraffin. The solid material allows for very slow penetration of water and permits the yeast to contact only water that penetrates therethrough. The immobilized yeast is coated on an inside surface of a container or on a surface of a closure such as a stopper that is on the inside of the container when closed. After adding a food or beverage and closing the container, the immobilized yeast removes oxygen from the container. The closed container and its contents can be pasteurized and the yeast retain sufficient viability to remove oxygen.

A spring pin is inserted into the horizontal orifice keeping the abutted edges thereof up so as to prevent a leakage of lubrificant.

Abstract: A hot flaw detector is equipped with a sensor holding member that has a circular opening through which the material to be inspected will pass and that holds a flaw detecting sensor. Provision is made of an annular cooling liquid injection port that is open at an end of the sensor holding member adjacent to the inner peripheral wall of the circular opening, and provision is further made of an annular cooling liquid introduction port that is open at the other end of the sensor holding member adjacent to the inner peripheral wall of the circular opening. The cooling liquid is injected from the annular cooling liquid injection port, and forms a liquid film along the inner peripheral wall of the circular opening, and is recovered through the annular cooling liquid introduction port. The inner peripheral wall of the sensor holding member is effectively cooled by the liquid film which drips little onto the material to be inspected.
