Title: Ion test means having a porous carrier matrix
Inventor: GANTZER MARY LOU
IPC: G01N33/52
Filed: 1985-02-11
Granted: 1988-12-01
Abstract: The present invention resides in the discovery of a new test means for detecting the presence of an ion in an aqueous test sample and determining its concentration. The test means comprises a porous carrier matrix substantially uniformly incorporated with a) a homogeneous hydrophobic mixture containing three principal ingredients: an ionophore capable of forming a complex with the ion, a hydrophobic vehicle, and a reporter substance capable of interacting with the complex of ionophore and ion to produce a detectable response; and b) a buffering substance capable of providing a pH in the range of from about 5 to 10. A test device comprises the test means affixed to one upper flat face of an elongated support member. In use, the aqueous test sample is contacted with the test means or device. The presence and/or concentration of the ion in the test sample is then determined by observing any detectable response produced. The test means and device of the present invention provide rapid results, sufficient detectable response forming in most instances in at least a few minutes.

Granted: 1989-07-20
Abstract: ® In a continuous ink jet printing method for printing multiple lines of print (13-15), raster of drops is produced in which the differential charge between drops printed on opposite sides of an interline gap (17, 18) is increased in comparison with that between adjacent drops to be printed within a line (13-15). At the same time the number of guard drops is maintained the same or is reduced between the printable drops immediately adjacent to the interline gap, so that the distance between printed drops immediately adjacent to the interline gap is increased without increasing the number of drops in the raster.

Abstract: 57 A pressure relief device for an internally pressurised container. The device is imperforate, forms an integral part of the container surface, and has a concave annular outer area integrally joined to an inwardly protruding circular central area by an annular intermediate area. These areas have different thicknesses resulting exclusively from the device having been drawn from a metal blank. The juncture of the annular outer and intermediate areas forms a first circular line of strain hardened material having a reduced thickness and increased hardness and strength as compared to the material thickness, hardness and strength of the annular outer area. The cross sectional configuration of the device is such that upon eversion thereof occasioned by an overpressurisation of the container contents, the material along the first circular line will fracture at at least one location, thereby allowing the container contents to escape therethrough.

Abstract: When the feeding roll (5), arranged at the unwinding station (1), is near to depletion, a new full roll (105) is disposed between a pair of transfer arms (15) which are ready at a stand-by station, and the leading flap (205) of a paper web (105') from a new roll (105) is locked in a gripper device (51,54) arranged at the lower end of a pair of retractable arms (46) carried by a splicing carriage (40) which is movable on rails (39) from the stand-by station to the splicing station (2). Thereafter, the depleted roll (5) is transferred from the unwinding station (1) to a parking station (27), while the new roll (105) is transferred from the stand-by station to the unwinding station (2). Concurrently, the splicing carriage (40) is advanced from the stand-by station to the splicing station (31,34) bringing the leading flap (205) of the new paper web (105') to the splicing station.

Abstract: The device consists of a profiled base strip (1), a spacer (2) and a profiled cover strip (3), which can be set by means of toothing (24, 33) at a suitable distance from the profiled base strip (1) and thus adapted to the thicknesses of the glass panes or infilling panels (4) to be clasped. The profiled base strip (1) has a supporting and sealing region (12) on each side. This region comprises sealing lips (14) and a projection (15) with a convex supporting surface (16). The sealing lips (14) are sufficiently flexible to permit tilting of a pane (4); thanks to the convex supporting surface (16), however, the latter always rests on the projection (15). The flexibility is facilitated further by a constriction (17). In this way, it is readily possible to construct and seal perfectly even curved building parts, such as, for example, barrel vaults or domes. The profiled base strip (1) and the profiled cover strip (3) always remain the same. The adaptation to panes (4) of different thickness is achieved, in addition to adjusting the toothing (24, 33), simply by means of spacers (2) of different height. This simplifies storage considerably. <IMAGE>

Abstract: An interactive video system has a videodisc player, a joystick, a framestore, a display, and a control device for controlling functions such as reading of frames from the framestore to the display. The videodisc player stores several sequences of moving pictures with the frames of the sequences interleaved so that changes can quickly be made from one sequence to another. To mask the reduced frame rate of any one sequence, repeated frames from the framestore are given a alternate blue and red color casts. To give the effect of changing perspectives with motion, the portion of the framestore read to the display changes in dependence upon (ii) the joystick output and (ii) the existing location of the displayed portion in the framestore.

Abstract: The automatic compensation system, denoted by the abbreviation AFC, is a monobloc assembly which is totally insensitive to turbulence. According to the first part of the improvement, the system consists of two force sensor-comparators (1) mounted in series and providing for the fully automatic adjustment of the compensator as a function of the thrusts produced on the flywheel or rudder control bar whatever the attitude, height or speed. The system is completely adapted to the kinematics of the control circuits, whether rigid or cabled. The AFC is completely insensitive to three-dimensional accelerations and is noteworthy in that it also forms the basis of the system for validating orders given to the throttle control through the automatic control system which is the subject of the second part of the improvement and is denoted by the abbreviation AED. This automatic control system consists of a memory disc with double recording speed and transfer sectors allowing optoelectronic power regulation which is insensitive to turbulence for each memorised speed in a range from the initial approach speed (1.2 VS1) to the speed that must never be exceeded (VNE). <IMAGE>

Abstract: In grinding machines which have a rotary backing plate with an abrasive disc detachably fastened thereto, the abrasive disc is held on the one hand by a central fastening element, which only has the task of preventing radial displacement of the abrasive disc relative to the backing plate, and on the other hand by an adhesive coating which only serves to prevent the abrasive disc from slipping relative to the backing plate in the peripheral direction of the backing plate, the adhesion of which adhesive coating, however, is not sufficient to hold the abrasive disc in place on the bearing surface of the backing plate without the centring action of the central fastening element. The combination of a centring element with an adhesive coating producing a frictional connection permits simple exchanging of the abrasive discs and at the same time guarantees faultless function of the grinding machine. <IMAGE>
