Abstract: ABSTRACT OF THE DISCLOSURE:         A sample-taking appliance comprises several sensors arranged on a turntable like sensor carrier in such a manner that the application areas of the small sensor sponges decrease stepwise from the first to the last sensor.  By simple rotation of the turntable the sensors can be brought successively into a working position.  The sensor carrier is preferably accommodated in a housing which is open at the bottom and which is raisable and lowerable in the frame of the appliance by, for example, a threaded spindle.  The threaded spindle is driven by an electric motor.  For each sampling the sensor carrier is lowered until the cell voltage cor-responds to a predetermined desired value.  This produces sufficiently precise and reproductible measured values for the electrolytic current for ascertaining the removed layer thickness.  The appliance makes it possible to take material samples even from locations of high radiation loading.  The material layers removed as samples lie concentrically above each other so that the graduation of the application areas comes into full effect and the material samples taken by the small sponges and the radioactivity contained therein are not falsified.

Abstract: ABSTRACT OF THE DISCLOSURE     A shear is disclosed in a preferred form which is particularly suited for cutting and trimming hair and which in-cludes means for varying the length of stroke of the cutting blade or blades which reciprocate generally parallel to the longitudinal axis of the handle, so that the unit can be manipulated in a manner similar to a comb or brush.  The blade drive includes a transmission comprising a pair of eccentrics which are selectively phaseable to provide full range of stroke by addition and subtraction of their eccentric throws.  The eccentrics are retained in their selected phase relationship by spring and frictional means which provide an overload release permitting the eccentrics to rephase to zero stroke when the imposed load overcomes the phase-retaining means.  Control of the unit is effected by a rotatable and depressable button which controls the drive motor, adjusts the blade stroke by phasing of the eccentrics, and levers the cutting blade or blades from a retracted position into a cutting position.              This is a divisional of Canadian Patent Application Serial No. 353,121-filed May 30, 1980, which, in turn, is a divisional of Application Serial No. 299,494 filed March 22, 1978.

Abstract: BONDED SHEATH CABLE            Abstract of the Disclosure A cable which is capable of being made in a large pair size and yet which has excellent mechanical properties that maintain its integrity notwithstanding extremes in temperature during installation and shipping as well as during the rigors of installation includes a sheath system having a corrugated steel outer shield that is adhesively bonded to a plastic jacket.  The corrugated steel shield which is formed to have a longitudinal overlapped seam that is preferably unsealed encloses an aluminum inner shield that in turn encloses a multiconductor core. Advantageously, the sheath system includes a plastic jacketing material which is capable of resisting biaxial stresses which are aggravated in a bonded sheath system. This results in jacket integrity about the longitudinal seam of the outer shield notwithstanding a notched cross-section and an unsupported bridged portion of the plastic jacket adjacent to the seam.  Of additional benefit is a further characterization of the plastic as being one which because of its relatively low elastic modulus at conventional extrusion times and temperatures is caused to substantially fill the corrugations of the outer shield. The jacket plastic forms a surface-to-surface bond with the shield that is sufficient to prevent delamination of the outer shield and the jacket and to prevent buckling of the jacket during exposure to temperature extremes.

Abstract: ABSTRACT       In order to provide a passive electro-optical display medium in a matrix display device with sufficiently steep threshold with respect to the applied voltage and with a memory, a switching element is palced in series with each picture element.  The switching element is provided between a picture electrode of each picture element and a driving electrode.  The switching element is formed by a polysilicon island in which n+-doped regions are provided which are separated by a p-doped region.  As a result of this, two series-arranged, oppositely directed p-n junctions are formed of which always one is reversely biased.  The width of the p-doped regions is so samll that punch-through occurs between the two p-n junctions before one of the p-n series resistance of the switching element is negligibly small so that a favourable Ronn/Roff ratio obtained and the picture elements can be driven with comparatively low voltages.

Abstract: DOWN FLOW APPARATUS FOR DISPENSING VISCOUS MATERIAL AND METHOD OF LOADING SAME                           Abstract Simple apparatus permits material, such as a hand cleaner whose viscosity is too great to flow downward under the force of gravity, to be loaded by inverting a can of the material and pressing downward onto the top of a reservoir sleeve.  For pumped dispensing, two rubber valves of the "duck-bill" type are provided in the flow line downward from the reservoir bottom wall.  While their lips are so soft as to be unable to restrain the down flow of conventional liquid, this is no problem when used with the viscous material.  The material is dispensed by pumping until its level in the reservoir is so low that an air channel forms downward through the material to the valved flow line, preventing further dispensing.  At this stage, inverting and pressing downward a second can of material drives air in the reservoir downward through the air channel so formed and out through the soft rubber valves, so that dispensing can recommence.

Abstract: ABSTRACT A deburring method and apparatus is presented wherein a cylindrical brush rotationally contacts the workpiece.   The brush includes a mandrel having a central axle to provide support during use.  To the mandrel is attached a multiplicity of long bristles. Each bristle is flexible and has impregnated therein a plurality of  abrasive particles.   The  population density of the bristles on the brush is such that the outwardly-extending ends can readily flex both in the plane of rotation and sidewise along the lengthwise dimension of the brush.  Setting the brush so that the bristle ends overlap the surface of the workpiece being deburred,  each bristle makes  a  slapping contact therewith.  This results in 1 to 2 inches of each bristle being dragged endwise across the surface of the workpiece.  The endwise movement of each bristle causes the abrasive particles imbedded therein to abrade the sharp edges of the workpiece.  An automatic conveyor may be used to feed workpiece stock past the rotating brush at a predetermined rate.

Abstract: ABSTRACT     This invention relates to apparatus for the control of process air flow.  One embodiment, useful as an air control valve in con-trolling the caliper of paper leaving the calender rolls in a paper-making machine, comprises a longitudinally moveable, spool-shaped valve core positioned within a cylindrical valve chamber which acts as a common receptacle for two air sources, one at each end of the chamber, wherein the length of the chamber is substantially equal to the length of the chamber.          The chamber has an egress aperture in its side wall.  Selective positioning of the core by moving it longitudinally permits the flow of air from both sources to be controlled simultaneously.          By that means, air may be caused to flow from neither or either (but not both) of the air sources, through the valve chamber and out through the egress aperture to a desired location, such as the surface of a calender roll, for the purpose of altering its diameter totally as a result of its temperature being changed.
