Abstract: ABSTRACT OF THE DISCLOSURE           An anti-freezing system for a windshield-wiper of a vehicle including a cut off device, which may be a relay, responsive to a temperature sensor which senses the ambient temperature. The cut off device energizes a heater to heat the windshield-wiper when and only when the ambient temperature as sensed by the temperature sensor is below a predetermined value.  The system may include a control device, which may be a relay, responsive to the output of an electric generator provided in the automotive vehicle and adapted to disable the heater unless the electric generator is delivering power.          The system may further include a manual override switch whereby the heater may be supplied with power, irrespective of the state of the cut off device.  The heater may be provided extending along an elongated wiper support, or may be embedded in a wiper blade supported by the wiper support.  The temperature sensor is preferably provided on the windshield-wiper in a position where the temperature sensor is free from the influence of the heater.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention contemplates a process for treating an isotropic carbonaceous graphitizable pitch with an organic fluxing liquid to provide a fluid pitch which has suspended therein substantially all of the quinoline insolu-ble material in the pitch and which solid material is readi-ly separable by filtering, centrifugation and the like. Thereafter, the fluid pitch is treated in at least two steps with an antisolvent compound, the sum total of which is suf-ficient to precipitate at least a substantial portion of the pitch, the amount of antisolvent employed in each step in-creasing from the first step to the last step.  In a parti-cularly preferred embodiment of the present invention, the fluid pitch is treated in two steps with an antisolvent compound with from 5% to 15% of the antisolvent compound being used in the first step and from 85% to 95% of the antisolvent compound being used in the second step.

Abstract: SELF-GUIDING TYPE MEDICAL    VASCULAR CATHETER   ABSTRACT OF THE DISCLOSURE    Disclosed is a self-guiding type medical vascular catheter made of a synthetic resin hollow monofilament. The catheter is comprised of a tip part, a relatively flexible part having a smaller diameter than the other parts, a tapering part and a manipulating part, these four parts continuously forming a line, in that order, along the monofilament axis.  At least the tip part and the manipulating part have X-ray impermeable metal inserted in the respective hollows thereof.  The X-ray impermeable metal has a diameter smaller than that of the hollow at least in the manipulating part so that there is formed a space within the hollow, which space defines a lumen for permitting a liquid and/or a gas to pass therethrough.  The lumen is opened to the outside of the monofilament body through an inlet opening at the distal end of the manipulating part and through an outlet opening bored in the tip part, the relatively flexible part, the tapering part, or the other end of the manipulating part or in close proximity thereto.

Abstract: ABSTRACT A vibratory seismic energy source capable of generating signifi-cant energy over a broad frequency band.  The vibrating baseplate and asso-ciated structure are designed for minimum size and weight, while retaining the structural strength to permit high actuator forces.  The weight of the transport vehicle is applied to a substantially horizontal hold-down plate that is interposed between the piston-cylinder assembly and the baseplate. This horizontal plate is coupled to the baseplate through resilient means having compliance such that dynamic motion of the baseplate is decoupled from the hold-down plate and transport vehicle.

Abstract: ABSTRACT OF THE INVENTION      A blood oxygenator which includes a new hollow fiber element and a method for making same.  The oxygenator ele-ment utilizes gas permeable hollow fibers to transfer oxygen into and carbon dioxide from blood flowing around the outside of the fibers while oxygen flows through the fiber lumens.  The hollow fibers are arranged in a plurality of layers in annular ring form on a hollow cylindrical core with the ends secured to each other and to the core in spaced apart tubesheets.  Each of the layers of helically wound fibers comprises hundreds of axially spaced apart fibers that are subtantially equally radially distant from the peripheral surface of the core so arranged that the fibers in the adjacent layers cross each other to form small interconnected gaps that permit thin film, radial direction blood flow through the gaps with a low blood phase pressure drop and efficient gas transfer.    The method comprises the steps of forming the hollow fibers into a tape of substantially uniformly spaced apart fibers, and spirally winding that tape on a supporting hollow core to form the new blood oxygenator element.    The new blood oxygenator element is sealed into a shell to form spaced apart oxygen header chambers at opposite ends of the core that are sealed from the annular blood chamber that surrounds the blood oxygenator element; the shell is provided with inlet and outlet ports for supplying oxygen to one header chamber, through the hollow fiber lumens and out the opposite chamber while blood is supplied to the core, permeates radially outwardly around the hollow fibers and through its layers to the surrounding annular blood chamber and exits as purified and oxygenated blood through the outlet port.    The blood oxygenator is integrated into a single unit assembly having a top blood reservoir attached to a blood heater that is attached to the blood oxygenator in vertical array.
