Abstract: ABSTRACT OF THE DISCLOSURE:       A measuring arrangement at a roller way formed by rotatably mounted rollers includes a supporting body movable along the roller way and thus setting the rollers in ro-tation. At the supporting body, sensors are arranged which coact with the surface areas of the rollers and measure the distance between the surface areas of the rollers and a neutral line provided within the supporting body. In order to be able to find out distorted or eccentrically mounted rollers by continuously moving through the measuring ar-rangement, the supporting body, on the side facing the roll-er way, has at least three sensors arranged at a distance from one another in the direction parallel to the moving direction of the supporting body. The sensors measure the surface area of a roller in subsequent angular positions.

Abstract: ABSTRACT             The invention is concerned with a control device for an artificial respirator, which comprises a solenoid-controlled valve for air and a solenoid-controlled valve for oxygen, both valves being of the variable flow type as a function of the plunger travel, and discharging into a manifold, a timebase circuit for fixing both the respiratory frequency and the ratio I/E of the inhalation time to the exhalation time during each period; a mixer for fixing both the overall respiratory flow and the proportion of oxygen in the gas supplied by  a  regulator; and two signal gene-rators each linked to and controlling the opening of an associated solenoid-controlled valve.  The timebase circuit out-put is connected to inputs of the generators in order that they may control the opening of the valves during the inhalation time, the generators being further connected to respective outputs of the mixer for receiving signals corresponding to the extent of opening of the valves during the inhalation period.  The mixer is connected to the timebase circuit for receiving a signal therefrom corresponding to the ratio I/E to correspondingly adjust signals proportional to res-piratory flow and oxygen proportion.  The valves are opened to an extent such that during the inhalation period, each valve allows a quantity of gas to pass which corresponds to the mean flow rate during the period.

Abstract: A method of preventing corrosion in boiler-plant equipment ABSTRACT     A method of preventing corrosion in boiler-plant equip-ment when cooling flue gases originating from a combustion plant, such as flue gases containing sulphur oxide or organic acids, to a temperature beneath the acid dew-point of the gases, in a cooler having heat-exchanging walls.  The flue gases are passed to the cooler at a temperature above the acid dew-point.  Those surfaces of the heat-exchanging walls, over which the gases flow, are held at a temperature beneath an upper permitted wall-temperature in respect of the material from which the walls are made, and in respect of the prevailing partial pressure of water vapour present in the gases, by means of a coolant, suitably water, located on the other side of the heat-exchanger walls.  The partial pressure of the water vapour in the gases can be increased by applying one of the following steps: supplying water or hydrogen-containing compounds to the combustion process, adding water or hydrogen-containing compounds to the gases, or cooling the gases at elevated pressures.

Abstract: ABSTRACT OF THE DISCLOSURE              A novel internally pivoted torque device for weight-in-motion or for static scales is provided herein.  It includes at least four internally pivoted torque-transmitting tubular arms arranged around the perimeter of the fixed bed for the load-supporting platform. One portion of each of the torque-transmitting tubular arms is supported with respect to a fixed peripheral frame base structure of the fixed bed, and with another portion of each of the torque-transmitting tubular arms being supported in guideways with respect to a central load-supporting platform of the fixed bed.  The improved mounting for the torque arm includes a pair of spaced-apart, vertically disposed inner and outer guideways extending along chords of the end of the torque-transmitting tubular arms.  A horizontally extending hardened wear surface intersects the guideways, to divide each inner and outer guideway into an upper and a lower guideway.  Four support shoes are provided, namely an inner upper and an inner lower support shoe as well as an outer upper and an outer lower lower support shoe.  Each such shoe except for only one of the inner shoes has a broad arcuate support surface of each of the four shoes is disposed in an associated guideway and bears against the hardened wear surface.  The broad arcuate support surfaces bear against respective upper and lower wear plate portions of the central load-supporting platform and of the outer fixed frame.  The broad flat support surface is secured with respect to a respective upper or lower surfaces of the outer fixed frame.  For a given weight, the torque on the torque tube member is thus reduced by a significant amount, i.e., seventy-five per cent or more.  This significantly reduces its weight, its cost of production and its cost of operation.

Abstract: ELECTRONIC CONTROL FUEL INJECTION SYSTEM FOR SPARK IGNITION INTERNAL COMBUSTION  ENGINE                   Abstract of the Disclosure An electronic control fuel injection system for a spark ignition internal combustion engine is disclosed which controls air flow rate as a function of fuel flow rate by converting an operator's depression of an accelerator pedal to an electric signal, applying the signal to a computer which preferentially determines the fuel flow rate and then the air flow rate, and feedback controlling the air flow rate by using the determined air flow rate and an actual air flow rate sensed by a pressure sensor provided at the upstream and downstream sides of a throttle valve and/or a throttle opening sensor.  The computer also receives signals representative of the fuel line pressure and the air pressure in a region adjacent one or more injectors and uses this in adjusting the supply of fuel to the injector(s) to obtain a predetermined constant pressure difference there-across. A unique digital flow control valve may also be used to precisely adjust the air flow rate.  The system eliminates auto-mobile "hesitation",while satisfying the requirements of fuel economy and low emissions.

Abstract: TITLE:     "PLANE DIE-CUTTING MACHINE"           INVENTOR:  Mr. Angelo BARTESACHI,  an Italian citizen, residing at Via Caduti a Fossoli 22, LECCO, Como, Italy ABSTRACT OF THE DISCLOSURE    The invention concerns a plane die-cutting machine for die-cutting laminar material, of the type comprising a plane punch and an arc-shaped counter punch, which is controlled by moving mean pressing the same against a work material inserted between it and the punch, said counter punch being simultaneously rotated around a li-ne of instant-contact which runs along the punch.  To avoid impacts between the reciprocally moving parts, the invention provides extensions integral to the punch and to the counter-punch, which maintain the contact between these latter for a portion of the reciprocal oscillatory movement outside the die-cutting area, so that said reci-procal oscillatory movement takes place with constantly contacting zones, like a blotter of blotting-paper.    The die-cutting area is defined in such a way that, when the reciprocally moving parts contact themselves at the ends of said extensions, between the die-cutting parts a hollow space is left, which is sufficient for the passa-ge of the laminar material under work.          - - - -
