Abstract: PNEUMATICALLY ACTUATED THREAD PROTECTOR FOR PIPES          Abstract A device for protecting external threads on the pin or male end of a tubular member such as drill pipe, tubing, casing, and the like (collectively referred to hereinafter as "pipe").  The thread protector includes a cylindrical inner sleeve including a cylindrical rigid member enclosed on one end by an overlapping end wall and open at the other end thereof, and further including a cylindrical expansible member in intimate contact with the exterior cylindrical surface of the rigid member.  A cylindrical thread shield member is disposed concentrically around and outwardly spaced from the inner sleeve such that an annulus is formed to receive the threaded segment of the pipe.  Valve means for inflating and deflat-ing the expansible member communicate through an upper end of the thread shield member and the upper end of the rigid member to the inner cylindrical surface of the expansible member such that the expansible member is urged toward and into contact with the received pipe and in turn may be disengaged therefrom.

Abstract: ABSTRACT This invention relates to improvements in methods and apparatus for measurement to drop flow in intravenous fluid flow control systems.  While observation of the rate of drop flow via the drip chamber is a simple way of controlling the amount of liquid fed to a patient over a period of time, its ultimate effectiveness requires that a relatively constant vigil be maintained on the drop flow, lest it cease entirely due to exhaustion of the liquid supply or become a continuous stream and perhaps increase the rate of liquid introduction to the patient to a dangerous level.  The present invention provides an improved electronic method and apparatus for evaluation to the quality  of drop detection in parenteral administration of medi-cal fluids, wherein the waveforms of electrical signals repre-senting drop flow detection are evaluated for conformity with both prescribed amplitude and time duration characteristics. Separate counters record the total number of drop events eval-uated and the portion of the total which are determined to be non-conforming, and the latter counter triggers alarms if a predetermined limit is exceeded within a prescribed number of total events.

Abstract: ABSTRACT         This invention pertains to plural electrodes for application to a living subject having skin, to accomplish effects related to the passage of electric current.  Using known electrodes in direct current applications frequently results in iontophoretic burns to the patient, generally at the negative electrode. These burns are not caused by elevated temperature but by a spontaneous effect of the ele?tric current on the skin.  These burns require a relatively long time to heal, and can result in formation of unsightly and highly undesirable scar tissue.  According to the present invention, at least the area of the negative electrode in contact with the skin is covered with felt-like material, preferably m?istened,  and having a thick-ness in excess of three millimeters.  Compliance with a current-time limitation according to the method essen-tially avoids iontophoretic burns.  Electively, this negative electrode structure allows increasing the size of the positive electrode, permitting a larger treatment current with reduced discomfort.  Intermingled positive and negative electrodes may be used.

Abstract: ELECTROMAGNETIC CLUTCH WITH ANTI-JAM CAM ACTUATION        Abstract of the Disclosure A cam actuated clutch of the type in which an armature is drawn into engagement with pole faces formed on a rotatable input member by energization of an electromagnetic coil. The armature is drivingly engaged with an input member by a plurality of balls cooperating with conical recesses formed in opposing radial surfaces, while the torque transmitted through the clutch by engagement of the armature causes a  camming action between balls and recesses by relative rotative and axial movement between the member surfaces formed with the recesses, urging the armature into tight engagement with the pole faces. The anti-jam feature consists of an arrangement for limiting the camming forces generated between the balls and the recesses by creating a spring force resisting the relative axial movement between an intermediate member formed with one set of conical recesses, with the opposing set of conical recesses formed in the armature. A positive stop prevents relative movement after a predetermined relative travel between the intermediate member and the armature to limit the camming force to the level produced by the spring upon engagement of the positive stop.      The positive stop acts to limit relative rotation by pins passing through openings in the armature sized to allow a predetermined extent of relative rotation to limit the camming action.      The intermediate member comprises a spline plate, splined to the input member so as to be rotatably connected thereto while accommodating the axial movement caused by the camming actuation.

Abstract: IMPROVEMENTS IN OR RELATING TO CLOTHESLINES          ABSTRACT OF THE DISCLOSURE            A collapsible clothesline intended to be stored in situ in the ground and to be erected by water pressure.  The clothesline comprises a casing intended to be located in a bore in the ground and a stem which is retractible into and extensible from the casing.  The stem itself consists of an inner and an outer stem element, with the former being retractible downwardly into and extensible upwardly from the latter.  A number of arms, linked by lines for supporting laundry, are pivoted to the outer stem alement and are connected by ties to the upper end of the inner stem element.  When the inner stem element is extended from the outer stem element, with the outer stem element already extended from the casing, the ties pull the arms up from a storage position, in which they lie alongside the stem, to a use position, in which they extend radially from the stem.  The clothesline is erected by supplying water pressure to the casing interior and collapsed by relieving such pressure.

Abstract: ABSTRACT OF THE DISCLOSURE            The specification discloses a device for centrifuging liquids and a means for analysing or processing sets of liquid samples and comprising an aforementioned device.  More particularly, it relates to a device for centrifuging liquids containing particles or cells in suspension.  The invention provides a liquid-centrifuging device which is free from the need for a vertical axis of rotation.  The centrifuging device is characterised in that the vessel for holding the liquid to be centrifuged has a shape and is made of a material such that the liquid therein is kept inside it by the action of electro-statis forces even if the vessel is not rotating and its orifice is facing downwards.  As a result, the vessel can be disposed in an invariable position relative to the axis of rotation.  This invariable position is the position for centrifuging, i.e. at which the free surface of the liquid in the vessel faces the axis of rotation.  The axis of rotation may be in any direction but is preferably horizontal.  Preferably the edge of the orifice is continued, at an angle to the vessel wall and outside it, by a collar or the like in one piece with the rest of the vessel, and the flange between the collar and the vessel is at an acute angle or has a small radius of curvature.  According to another feature the same result (i.e. of holding or retaining the liquid in the vessel) can be obtained by using a vessel, having a shape and made of material such that the liquid sample therein is kept inside it by the action of surface tension forces, even when the vessel is not rotating and its orifice is facing downwards.

Abstract: Abstract of the Disclosure      W.E. 47,918 A steam generator tubesheet  is serviced by end effectors  mounted  on  a  slew  table  cantilevered  from a carriage  slidable  along  an  arm  rotatable  in  a  plane parallel to the tubesheet. In servicing a selected hole in the tubesheet,  the rotatable arm and the carriage arm are driven to positions which allow the cantilevered slew table to be slewed to a predetermined angle associated with the selected  hole.  The  arm and carriage are then driven to positions which place the end effector under the selected hole  taking  into account the offset of the slew table. Alternatively,  a determination is  first made whether the arm and carriage can be positioned within preset limits to place the end effecter under the selected hole using the existing slew angle.  If so, the existing slewed angle is used but, if not, the table is slewed as mentioned above.
