Abstract: ABSTRACT OF THE DISCLOSURE        An improved hydroconversion process for carbonaceous materials wherein a dihydrocarbyl substituted dithiocarbamate of a metal selected from any one of Groups IV-B, V-A, VI-A, VII-B, and VIII-A of the Periodic Table of Elements or a mixture thereof is used as a catalyst precursor. The improved process is effective for both normally solid and normally liquid carbonaceous materials and for carbonaceous materials which are either solid or liquid at the conversion conditions.  The hydroconversion will be accomplished at a temperature within the range from about 500 to about 900°F, at a total pressure within the range from about 500 to 7000 psig and at a hydrogen partial pressure within the range from about 400 to about 5000 psig.

Abstract: C A N A D A         INVENTION PARTICULATE MATERIAL LOADER     INVENTOR JAROSLAV KOPERNICKY     ABSTRACT OF THE DISCLOSURE           A filterless  loader which entrains particulate material in air flows is described. The loader includes a reservoir in which the materials may be accumulated and from which the materials may be delivered under gravity through a, lowermost outlet to appropriate processing, equipment. A closed air circuit draws the particulate material into the reservoir from an external storage bin or container. The closed air circuit includes air supply and return conduits communicating with the interior of the reservoir, and a fan unit which circulates air through the conduits.  The fan unit draws air from the interior of the reservoir, and forces the air into an inlet end of the supply conduit.  A gap is maintained at the junction of the air supply and return conduits external to the reservoir, and supply conduit air flows are guided by a nozzle across the gap into the return conduit.  The junction is inserted into the storage container thereby introducing the particulate material into the path of the closed air circuit.  An air flow diffusing region between the return conduit and the air inlet of the fan unit causes particulate materials entrained in the return air flows to settle to the bottom of the reservoir where they can be delivered under gravity to the processing equipment.     Particulate material is confined to the closed circuit air flows therehby preventing scattering to the environment, and no filter commonly used in prior loaders is needed to reduce emission of particles.

Abstract: ABSTRACT           The invention disclosed relates to a method for the purification of hemoglobin by the technique of affinity chromatography.  Contrary to current belief, the binding of oxygen and selected polyanions to hemoglobin is not mutually exclusive.          The novel method comprises immobilizing a polyanion which specifically binds hemoglobin via its polyanion binding site, on a chromatographic gel and passing the hemoglobin containing solution or mixture through the gel.  The hemoglobin is thus retained in the gel, while impurities are eluted from the gel.  The novel method is also applicable to the separation of unmodified hemoglobin from a liquid reaction mixture containing modified and unmodified hemoglobin.

Abstract: MEDICAL VENTILATOR SYSTEM     ABSTRACT OF THE DISCLOSURE       A volume ventilator is disclosed which has a balloon valve type exhalation valve for permitting release of gases to the ambient environment during the exhalation period of artificial ventilation or spontaneous breathing, or when there is excess proximal pressure in the ventilator system. A pressure transducer continuously senses  the proximal pressure  in  the  ventilator  system  and  sends  to  a microcomputer controller and associated circuitry of the ventilator system a signal indicative of the instantaneous proximal pressure.  The pressure in the balloon, which is the pilot pressure of the exhalation valve, is regulated through a jet venturi type pressure controller which is connected to a source of pressurized gas.  The gas flows through the jet venturi, wherein its flow rate is regulated by a ball valve moving against a suitable valve seat.  A static port connected to the gas flow in the jet venturi provides the pilot pressure for the balloon.  The ball valve is controlled by a stepper motor through a cam follower.  The stepper motor is controlled through electronic  signals generated in the computer control in response to the difference between the instantaneously sensed proximal pressure,  and the pilot pressure required to be present in the balloon in accordance with an algorithm or preselected pilot pressure-versus-time function.    The  algorithm  or  preselected  pilot pressure-versus-time function is stored in the memory of the computer.  Accurate servo control of the flow of respiratory gas to the patient is accomplished by a flow control subsystem which incorporates a flow control valve controlled by a second stepper motor.  The flow of the respiratory gas is monitored, downstream of the flow control valve, by a flow transducer.  The flow transducer sends to the microcomputer controller a signal indicative of the instantaneous flow rate of the  respiratory gas.   The microcomputer controller compares the instantaneous flow rate to a flow rate value required by an algorithm or preselected flow rate-versus-time function stored in its memory.  The microcomputer controller then sends a signal to the second stepper motor to adjust the flow control valve to provide the flow rate instantaneously required by the preselected function or algorithm.

The tracks are defined by aligned upper and lower "U"-shaped channel members providing rails.   Each track is defined between adjacent pairs of upper and lower members.  Gates at either end of the tracks control movement of the packages into or out of the carrier.  The carrier can be loaded and unloaded by means of apparatus including an inclined ramp on which the carrier can be releasably located, the packages being fed into the top of the ramp to fill the carrier, and sliding to the bottom of the ramp to empty the carrier of soldered packages prior to re-filling. Movement of the packages down the ramp is controlled by gates.

Abstract: ABSTRACT OF THE DISCLOSURE    A display processor in a raster graphics display system includes a transformation, clipping and mapping feature which controls the transformation, clipping and mapping of graphics data.  A control byte contains 5 bits identified as:  M- Window to viewport mapping; P-perspective projection; D-2D/3D mode; T-transformation; and C-clipping.  Each bit in the control byte is tested to determine what operations are to be performed on the figure to be drawn.  For example, if the D bit is one, indicating a three dimensional figure and the T bit is one, indicating transformation, and the C bit is one, indicating clipping, the P bit determines whether the clipping will be perspective or non-perspective clipping and the M bit determines whether the figure to be drawn is to be mapped to the view port.

Title: Shear strength testing of foundry sands - using a force applied in two planes vertical to test-piece axis
IPC: G01N3/24
Filed: 1973-06-08
Abstract: Shear strength of foundry sand mixts is determined across two planes vertical to the central axis of a cylindrical test-piece. The method results in the virtual elimination of any bending force in the applied stress, thus leading to more accurate measurements. The cylindrical test-piece is placed between two jaws, both of which have a semicircular face in contact with the test-piece, however, one jaw has a large slot in the centre of the semi-circular section so that this surface only contacts the end portions of the test-piece. Conversely, the other jaw is cut away at both ends leaving a centre section the same size as the slot in the mating jaw. If no test-piece was present, the jaws would mate but when a test is conducted, a shearing force is applied across the test piece in two planes. Keys and pegs ensure accurate location of the two jaws. Press. is applied by a hand-operated cylinder and the force measured with a manometer. Considerably higher shear test results are obtd.
