Abstract: ABSTRACT OF THE DISCLOSURE          This invention relates generally to improvements in an improved valve control system for syringe pumps.  Prior art syringe pumps are often overly complex and unstable or inaccurate in their valving and motor control systems.   The present invention overcomes these deficiencies by providing apparatus which repetitively and sequentially opens and closes a pair of intake and output I.V. tubes communicating with a syringe, the tubes alternating between opened and closed states, one tube always being open while the other is closed, by means of a pair of L-shaped pivotal tube pinchers, one pincher controlling each I.V. tube.  The tube pinchers are alter-nately pivoted to a non-clamping, tube-open position by a spring biased, intermittent motion, reciprocating slide bar under the con-trol of a reversible, rotating cam, the cam being driven by a syringe drive motor which is also used to drive the syringe through fill and pump strokes.  A sensor may be provided to determine whether the syringe pump performs a fill stroke or a pump stroke.  Control of the intake I.V. tube and the output I.V.  tube is aided by a pincher spring secured at one end to the intake tube pincher and at the other end to the output tube pincher, the pincher spring extending there between and biasing the pinchers toward the clamp-off position.  The tube pinchers, under control of the rotary cam, are adapted for snap action positioning, so that only one tube is open and only one tube is closed at any time.

Abstract: Abstract of the Disclosure A mass of diamond crystals in contact with a mass of eutectiferous silicon-rich alloy and a silicon carbide or silicon nitride ceramic substrate axe disposed in a container and placed within a pressure transmitting powder medium.  Pressure in applied to the powder medium resulting in substantially isostatic pressure being applied to the container  and its contents sufficient to dimensionally stabilize the container and its contents.  The resulting shaped substantially isostatic system of powder-enveloped container is hot-pressed, whereby fluid eutectiferous sili-con rich alloy is produced which infiltrates through the interstices between the diamond crystals and contacts the contacting face of the substrate sufficiently to produce, upon cooling, an adherently bonded integral composite.

Abstract: ABSTRACT OF THE DISCLOSURE:          A process of producing a town-gas-grade fuel gas having a calorific value below 18,000 kJ/standard m3 (4300 kcal/standard m3) by a catalytic reaction of methanol and water vapor under a pressure in the range of about 10 to 50 bars.  80 to 95% of mixed feedstocks containing water vapor and methanol in a weight ratio of about 0.5 to 1.5 are fed at a temperature of 300 to 700°C to a first reaction zone which contains a nickel catalyst that contains 25 to 50% nickel by weight as an active component.  The remainder of the mixed feedstocks together with the effluent gas withdrawn from the first reaction zone are then fed at a temperature of 200 to 400°C to a second reaction zone, which contains a copper catalyst that contains about 40 to 70% copper by weight.  The process of the invention permits to produce a town-gas-grade gas in a technologically simple manner and without need for extraneous gas sources.

Abstract: ABSTRACT OF THE DISCLOSURE       Novel clamps are provided to enable a modular utility unit to replace a door on a van-type wheeled vehicle.  The modular utility unit includes: a utility-containing and appliance-containing unit having a facade, a base, a top, sides and an exterior surrogate door panel; utility appliances disposed with-in the modular utility unit.  The clamps comprise a hollow housing (e.g. a hollow rectangular parallelipiped housing) having a slot on one side thereof and provided with securement means on the housing; a rotatable screw member mounted longitudinally therein (preferably wherein one end of the screw member is freely rotatably mounted to one end of the housing and the other end of the screw member is provided with an attachment nut); adjusting means secured to one end of the rotatable screw member; a trav-elling rail member disposed along said screw member; and a piv-otable arm being adapted to protrude from the slot and being adapted to pivot as a result of rotation of the rotatable screw member, (e.g., as a result of longitudinal movement of the travelling rail member due to rotation of the screw member by the adjusting nut); When the door of the vehicle is removed, the clamps cooperate with a door frame of the vehicle for securing the utility unit within the vehicle.  Releasing the clamps en-ables removal of the utility unit from the vehicle, and the door of the vehicle may then be replaced.  Thus, by the use  of these clamps, a van-type vehicle can be converted to a utility unit-containing camper van merely by replacing one door thereof with the above described modular utility unit.

Abstract: ABSTRACT           A self-contained service module incorporates a water cooled internal combustion engine as a primary power source which drives a low-pressure, high volume forced air ventilation system; a water cooled, high-pressure air com-pressor; and an alternator.  Large diameter steel tubing is utilized as a basic framework for the system and provides a dual function by supporting the primary components of the system and by serving as a reservoir for the high-pressure air.  A heat exchange radiator is provided to remove heat from the engine and air compressor cooling liquid and heat the low-pressure air in the ventilation system.  When heated air is not required, the radiator is moved to a second position so that air passing therethrough is exhausted from the unit and fresh air at ambient temperatures is provided by the ventilation system.

Abstract: ABSTRACT OF THE DISCLOSURE A distance-amplitude compensation system for use in correcting the output from an ultrasonic pulse echo testing circuit.  Prior to the testing of workpieces, ultrasonic pulses are applied to one or more test blocks having a plurality of equally sized reflectors positioned at varying depths therein.          Ultrasonic pulse echoes returning from the reflectors are of differing amplitudes as a result of the near field and far field effects and attenua-tion of the test blocks.  These echoes are transduced into electrical pulses and applied through a receiver to an oscilloscope display.  A function generator provides a voltage vs. time curve which is also applied to the oscilloscope and is adjusted by the operator to conform to the peak ampli-tudes of the displayed electrical pulses.  During subsequent testing, this voltage function is applied to a control signal generator which, in accordance with a predetermined relationship, modifies the voltage function into a control signal which is applied to the receiver.  The control signal varies the receiver gain with time to attenuate and equalize the displayed pulses to a preselected amplitude.  The equalized pulses corresponding to the equal sized reflectors are dependent upon only the size of the reflector and are independent of the depth of the discontinuities within the test blocks.  As a result of the adjustment to the receiver gain by the control signal, the magnitudes of all displayed echo pulses from workpieces subsequently tested by the system will be dependent only upon the sizes of the corresponding discontinuities in the workpieces.
