Abstract: This invention relates to an electrochemical sensor system for the simultaneous and continuous measurement of the partial pressure of oxygen PO.sub.2 and carbon dioxide partial pressure PCO.sub.2 in fluids. The electrochemical sensor of the present invention is particularly useful for intra-arterial measuring PCO.sub.2 and PO.sub.2 in blood and is readily adapted to transcutaneous measurement of these blood gases by the addition of a heating element and minor configurational changes.

Abstract: A ground fault circuit interrupter which utilizes one trip coil to perform the combined functions of interrupting a circuit on occurrence of a ground fault as well as an under voltage condition. An electronic module supplies continuous current to the trip coil until a ground fault or under voltage condition occurs. The armature is spring biased in a direction away from the trip coil, with tension of the spring adjusted to pull the armature away from the trip coil when voltage in the coil decreases below a selected amplitude.

Abstract: A dispensing apparatus for machines for packeting cigarettes into hinged-lid rigid type cigarette packets is of the type comprising an intermittently rotating wheel having radially disposed compartments for housing individual cigarette packets. A dispensing channel is associated with the wheel and upper and lower heated plates cooperating with the compartments. A pushing member is provided at the end of the dispensing channel to push, during the normal operation of the apparatus, the individual packets into a first track coplanar to the dispensing channel. A control mechanism, should the wheel accidentally stop, acts on a pair of mechanical systems which cause the spacing apart of the plates from the compartments and further starts a timer.

Abstract: A smokable material for the tobacco industry, characterized in that it is formed in its major part with coherent spheroidal aggregates of entangled tobacco fibers having no preferential direction.

Abstract: The invention is concerned with a process for the production of a textured protein-containing edible product resembling cooked meat from a fibrous protein material without the use of a binder, in which the proteins are spun, the fibres obtained are subjected to a combined pressing and dehydrating operation in a mould, impregnated with a solution of aroma precursors and sterilized in a container. The process is characterized in that, with the fibres arranged substantially parallel to one another in the mould, the combined pressing and dehydrating operation is carried out by subjecting the fibres to mechanical compression in the axial direction.

Abstract: A toilet support for use by invalids and the like wherein one or more arms are mounted on brackets supported adjacent the hinge for the seat of the toilet bowl for movement into and out of operative position such that in one position the arms can be gripped and engaged by the invalid and in another position said arms are out of the way.

Abstract: A device to eject a fragment of a broken blade of an axially rotating mace by damping its kinetic energy, in order to prevent perforating the housing of the machine and the rupture of adjacent blades. The device is in the form of a helical ramp carried by the internal wall of the housing of the machine.

Abstract: An ultrasonic probe for measuring liquids at high temperature and under high pressure. The ultrasonic probe comprises a leak-tight protective sleeve which has an end face closed by a thin metallic wall. The protective sleeve contained internal elements which are in particular a transducing piezoelectric plate and a damping cylinder. The piezoelectric element has one face which is in mechanical and electrical contact with the internal face of the thin sleeve wall and the other face which is supported on a damping cylinder. The thin sleeve wall of the sleeve end face is constituted by a metallic layer obtained by cathodic sputtering.

Abstract: Refractory tubings, either in amorphous, polycrystalline or single crystal form, are made by moving a preformed tubing of a refractory material and a heated zone relative to each other, the heating zone providing sufficient heat to melt through the tubing and form a molten ring which is continuously advanced through the tubing. The heat source may be located externally or internally of the tubing wall or in both positions. The tubings may be formed as single crystals by using appropriate seeds; and by controlling the rate of movement of the tubing sections on either side of the molten ring the wall thickness and diameter of the final tubing may be adjusted.

Abstract: A supercharger set for internal combustion engines comprising two turboblowers the two axes of which being mutually perpendicular. The high-pressure turbine is mechanically coupled to the high-pressure compressor, whereas the low-pressure turbine is mechanically coupled to the low-pressure compressor. A single casing is used for the egress of the gases from the high-pressure turbine and their ingress into the low-pressure turbine.

Abstract: A method and a device for stopping a fuel-injection internal combustion engine, in which the injection pump is of the multi-cylinder single-housing type, comprising in supplying the housing of the pump with pressurized gas for separating the pump plungers and tappets from their actuating cams.

Abstract: Apparatus for controlling the position of a part, e.g. a feeler or work tool, along two orthogonal directions, the part being slideable in a first slide extending in one direction and mounted on a carriage movable along a second slide extending in the other direction and mounted on a support. The apparatus comprises a device for locating the position of the carriage on the second slide and the movable part on the first slide, a device for measuring the error in straightness of said second slide and a device for measuring the error in orthogonality of the first slide, each device comprising a laser generator for producing a laser beam parallel to the respective direction and a photoelectric detector in the path of the respective beam and subject to the respective error to be measured.

Abstract: A fluid-displacement radial piston machine, such as a hydraulic pump or motor, includes an eccentric member which is mounted on a shaft for displacement radially thereof to thereby change the eccentricity of a contact surface of the eccentric member which is engaged by sliding shoes of a plurality of working pistons. An arrangement for displacing the eccentric member includes a piston component which is connected to the eccentric member by two displacing portions and whose piston portion subdivides a compartment of the shaft into two actuating chambers into which pressurized fluid is selectively admitted through respective passages in the shaft and through a rotary transmission interposed between a source of the pressurized fluid and the shaft. One check valve is interposed in each of the passages and interrupts the communication of the respective actuating chamber with the rotary transmission when no pressurized fluid is admitted into any of the passages.

Abstract: Machine for edging and bevelling ophthalmic lenses comprising guide means r forming a small bevel on the edge of lenses having a relatively thick edge, said guide means comprising a guide member connected to the frame of the machine by means of a pair of links forming a parallel-link motion device, a pair of springs constantly urging said links to a stable position in which their longitudinal axes form a predetermined angle with the axis of the rotating spindle which supports the lens to be bevelled, a bearing member supported by a movable carrier for said spindle and urged for engagement with said guide member, one of the guide member and bearing member comprising a bar extending at right angles to the spindle axis and provided with coupling means capable of preventing any relative movement between the guide member and the bearing member in a direction at right angles to the spindle axis. The adjustments of the machine for forming the small bevel art thus greatly simplified.

Abstract: A container support useful for supporting flexible fluid containers in a suspended, upright position is described having a hinged arm with detented hinging means.

Abstract: A variable area metering tube is described having a non-linear graduated measuring scale wherein the scale compensates for non-standard variations in the cross-sectional flow area of the metering tube.
