Abstract: A flame retardant plywood panel has one or more structural core layers sandwiched between front and back veneer layers. In the preferred embodiment, the veneer layers are coated with an unfired ceramic material which hardens when exposed to a flame and prevents the flame from igniting the core and veneer layers. Perforations are preferably provided in the back of the panel for the ventilation of steam and other gases generated in the panel by exposure to high temperature.

Abstract: A sealed container provided with a valve opening and a resilient valve member self-biased into closing position. The valve is manually openable by a lever which is held in the open position by a rigid fuse-like element which melts after being subjected to sterilizing temperatures long enough to sterilize the container and its contents. The valve then closes sealing the container. The valve and a gasket between the container lid and base will permit leakage out of the box to permit the withdrawal of steam from the container when a vacuum is applied to the container exterior but will prevent reverse flow so that a vacuum is maintained within the container once one is created. The vacuum may be released by opening the valve, which simultaneously cocks it for the next sterilizing operation.An alternate approach includes a disposable, resilient valve member which plugs into a hole in the wall of the container and covers a valve orifice into the container.

Abstract: A combination air vent and air scoop for the roof top of a motor vehicle has an integral body with an air inlet scoop in the front and an air outlet vent in the rear. The scoop is opened and closed by means of a panel which has a closed position in which it rests flush against the body of the device and an open position in which it extends inwardly into the interior of the device. The vent is opened and closed by means of a second panel which likewise has a closed position in which it rests flush against the body of the device and an open position in which it extends into the interior of the device. Means are provided for actuating the scoop panel and the vent panel independently. Both the scoop and the vent can be opened and closed while maintaining the body of the device in a fixed relationship with the roof of the motor vehicle.

Abstract: In a drilling bit, a cone shaped cutter is rotatably mounted on a spindle on anti-friction bearings and on a friction bearing in the nose of the spindle. A passage is formed in the exterior cylindrical surface of the spindle nose in the load bearing zone. This passage is connected to a radial passage on the end or thrust bearing surface of the spindle, and the center of the thrust bearing surface communicates with a weep hole in the nose of the cutter. Cooling fluid is ducted through the spindle and through these passages to provide cooling directly in the area where the generated heat is the greatest and fluid flow a minimum in previous constructions.

Abstract: A mounting pin of circular cross-section is rendered eccentric and used to artifically agitate a motion snubber used to shock mount components of a nuclear power plant, thereby making possible testing of such a snubber without dismounting it.

Abstract: This invention relates to a device for adapting between an insulation displacement connector of one pitch and a standard plug or socket connector of another pitch using conductor inserts uniformly stamped and accurately offset to accommodate the difference in pitch by insertion into a molded insert guide.

Abstract: Immunosuppressive agents which are conjugates of an antigen linked to a D-glutamic acid:D-lysine copolymer are disclosed. Also disclosed are methods of preparing the conjugates and therapeutic methods for inducing immunological tolerance to antigens.

Abstract: A system for electronically representing in wave form plural physiological phenomena, viewing this representation, and simultaneously obtaining a labeled permanent photographic record of the representation. While of general application, the system has particular utility in low-cost medical observance and recordation of electrocardiogram wave forms. The data from the patient is presented on the cathode ray tube of an oscilloscope. This representation is viewed via an assembly of mirrors by the observer and simultaneously by a camera. When the observer is content with the output, he activates the camera which takes a permanent picture of the wave forms displayed on the cathode ray tube. The camera shutter is synchronized with the cathode ray tube display such that the shutter is held open for one complete sweep of the electron beam.

Abstract: A drill bit having three cone-shaped cutters is formed with two drilling fluid nozzles on opposite sides of one of the cutters and with an enlarged return passage for the drilling fluid being formed between the other two cutters. Flow restrictors adjacent the two nozzles restrict the flow of return fluid in those areas. A flow diverter in the dome area of the bit extends into the space between the cutters to better direct fluid across the bottom of the hole where cuttings are being generated by the cutter teeth.

Abstract: Polyethylene glycol or poly(oxyethylene)poly(oxypropylene) glycol block copolymers or mixtures thereof in a suitable buffer such as citrated saline, are added to blood plasma to preserve and protect blood coagulation factors and other proteins.

Abstract: Nutrient-rich ocean water from the aphotic zone of the ocean, which normally begins at about 100 to 200 meters below the ocean surface, is desalinated or partially desalinated in situ using electro-dialysis to leave the nutrients in the water. The nutrient-rich desalinated water thus obtained, being of lesser density than the surrounding seawater, naturally rises through conduits into the relatively nutrient-poor photic zone of the ocean and is dispersed therein, thus increasing the concentration of nutrients in the photic zone near the surface of the ocean. This increases the fertility of the near-surface photic zone, and thus increases the supply of harvestable food fish from the near-surface photic zone.

Abstract: A method for concentrating and purifying Factor VIII by selective cold precipitation in low ionic strength solution is disclosed.

Abstract: A fireplace heating unit comprises a continuous network of hollow tubular members situated in a fireplace. The tubular members absorb heat from the fireplace while air propelled by suitable air moving means passes through the tubular members absorbing heat therefrom. A portion of the air passing through the tubular members may be directed so as to impinge upon the flame in the fireplace and means are provided to control the direction and quantity of the flame-impinging air flow. The remaining air which is not directed onto the flame continues its passage through the tubular members and exits either directly into the room or into a device, such as an oven, for heating other objects. The invention is adaptable for use with either coal or wood fires and in one embodiment is adaptable for use in fireplaces which use a gas jet flame.

Abstract: An adjustable locking strut is connected to a pair of relatively movable mechanical elements and permits relative motion between these elements below a predetermined motion threshold. Above this predetermined motion threshold relative movement between mechanical elements is prohibited through the engagement of nonoverhauling threaded members connected to the mechanical elements. These nonoverhauling threaded members are specially designed so that when synchronized they do not engage one another. One of the nonoverhauling threaded members which is internally threaded forms a relatively large tubular inertia mass for sensing accelerated movement between the relatively movable mechanical elements.

Abstract: A method of oxygenating venous blood in a blood oxygenator wherein blood and oxygen are admixed by flowing blood, into which has been introduced bubbles of oxygen, through a three dimensional, open cellular mixing material having a substantial void volume. In one embodiment, the admixing chamber is provided by an upright cylinder having an open interior. In a second embodiment, the chamber has an annular interior configuration. In both embodiments, the open cellular mixing material completely fills the cross-sectional interior of the chamber. The resulting arterialized blood and blood foam rise to the top of the admixing chamber and are contained in a channel located at the top of the chamber and directed through this channel to the input of a defoamer chamber. A defoamer filter of annular configuration is retained within the defoamer chamber such that the defoamer inlet is located at the top of the defoamer filter within the interior annular space thereof.
