Abstract: ABSTRACT            ULTRASONIC PROBES        A wheel probe will detect flaws in workpieces over which it travels without the use of a coupling medium between the tyre and the test material.   The tyre (20) is filled with oil under pressure and houses a transducer (14).   When pressed against the test material the tyre elongates to bring the internal surface of the tyre into acoustically coupled contact with the transducer.   The transducer (14) is biassed towards the internal surface of the tyre (20).

Abstract: MULLS CONTAINING CHAIN STRUCTURE CLAY                      SUSPENSION AIDS     ABSTRACT OF THE DISCLOSURE         Liquid mulls having improved physical stability, consisting of a liquid phase and a dispersed solid phase. The liquid phase contains a major proportion of a nonionic surfactant and optionally contains a minor proportion of a nonaqueous solvent.  The dispersed solid phase is a particu-late material which is insoluble in the liquid phase of the mull.  The inclusion of chain structure type clays in the composition unexpectedly aids the physical stability of the mull, so insoluble particulate materials such as builders having ordinary particle sizes may be incorporated in the compositions.  Preferred compositions are substantially anhydrous to allow the optional inclusion of water sensitive detergency adjuvants, such as enzymes or bleaches, in the compositions.  The compositions may optionally contain 0% to 25% of a further dispersion aid selected from anionic sur-factants, cationic surfactants, zwitterionic surfactants and hydrotropic materials.  Such mulls have utility, for example, as detergent compositions.

Abstract: Abstract of the Disclosure There is described an electrohydraulic regulating device comprising a regulating cylinder, a regulating piston in the cylinder capable of being loaded at either end thereof for re-positioning the piston in the cylinder.  A pair of magnetically operable valves are connected to opposite ends of the cylinder, each of the valves also being connected to both supply and return conduits for conducting pressurized hydraulic fluid from a supply thereto and for returning hydraulic fluid to a reservoir therefrom, respectively.  The valves are operable to alternatively effect fluid communication between the respective supply and return conduits connected thereto and the respective end of the cylinder connected thereto to alternatively conduct hydraulic fluid to and from the respective end of the cylinder connected thereto.          A computer is operable to produce switch pulses of variable dura-tion to operate the valves to effect corresponding adjustments in the relative position of the piston in the cylinder.  Also included is a pair of restrictors, one of the restrictors being in one of the supply and return conduits connected to each of the valves, both of the restrictors being in the same respective conduits relative to the respective valves, whereby, when the valves are operated to effect piston adjustments, the pressure drop in the fluid between the valves is minimized to minimize the effects of the compressibility of the fluid and thereby permit enhanced accuracy in the adjustments.  Finally, there is provided a pair of pressure sensors.  One of the sensors is connected to the respective conduit of the device between each of the restrictors and the adjacent valve to detect a pressure change therein.  Each of the sensors is also connected to the computer for transmitting a signal thereto in response to the pressure change to indicate the operation of the adjacent valve.

Abstract: Title of the Invention:          IMPROVED AIR WEFT INSERTION NOZZLE CONTROL SYSTEM          Abstract of the Disclosure: The actuation of a nozzle utilized for propelling the yarn in an air weft insertion weaving system is controlled by means of a single rotary servo valve having an arrangement of ports adapted to be brought during valve rotation into registration alternately with an air pressure source and with the atmosphere for alternately pressurizing and venting a pilot chamber for opening and closing the nozzle. Preferably, the rotary valve includes a rotary spool enclosed within a sleeve of air permeable material to provide an air bearing for the spool. The actuation of the nozzle is determined by the movement of a diaphragm valve toward and away from the opening of a nozzle supply chamber under the control of the pilot chamber pressure, and the diaphragm is deformed into two annularly separated generally U-shaped convolutions opening toward the interior of the air supply chamber of the nozzle 80 that the movement of the diaphragm during opening and closing follows a "rolling" or progressively flexing action as the convoluting side walls telescope outwardly and inwardly relative to one another. Preferably, two substantially similar convoluted diaphragms are disposed in axially spaced oppositely directed relation, one exposed to the nozzle supply pressure and the other to the pilot chamber pressure. Advantageously, the interior space between such dia-phragm is vented to the atmosphere to maintain a pressure-free condition therein and clearances are provided to prevent entrapment of air resisting deflection of either diaphragm.

The longitudinal profile extends towards the stern substantially tangentially to the horizontal plane.  The chord of at least this aerofoil lies within the horizontal plane.  The lower portion of the body may have the shape indicated in lateral longitudinal regions and may have in a central region profile chords having a positive or negative incidence angle.          Conversely, the shape indicated may be realized in the central region, the profile chords having a positive or negative incidence angle being located in the lateral regions.  The highest point of the lower actuated portion of the body respectively the profile, is located between 30% and 50% of the length of the profile chord, that is to say the distance apart between the culminating point and the front end of the chord, respectively the chords, is less than 50% of the total length of the chord and preferably comprised between 30 and 50%.

Abstract: DEVICE FOR FEEDING DATA SUPPORTS IN A PROCESSING   ARRANGEMENT            ABSTRACT  OF THE  DISCLOSURE:       The device for feeding card-type data supports in a processing equipment includes a guiding path having at least one lateral abutment edge for aligning  the data support during travelling from an introduction slot to-wards a processing position within the equipment. The data support being correctly aligned during its travel along the guiding path, it may be processed during such travel by reading and/or writing data thereon. In accordance with a preferred embodiment, the automatic feeding and alignment of the data support is achieved by a frictional guiding wheel secured on a driving shaft which in turn may be pivoted about an axis normal to the plane of the data support card. Thus, the driving wheel may pivote between two predetermined positions, and in a first position in which the data support is first engaged, it will only exert a driving force on the data support, and immediately sub-sequently, the driving wheel will be pivoted into the second position by engagement of its peripheral surface with the wall of the receiving zone of the data support; when in its second position, the driving wheel will simultaneously exert both the driving force and an alignment force on the data support.
