Abstract: ABSTRACT OF THE INVENTION      A method and test device for determining the glucose concentration in a test sample containing from 1/2 tp 5  percent glucose are disclosed.  The method and test device involve incorporating urea-formaldehyde resin in a carrier matrix and subsequently impregnating the carrier with an enzymatic testing composition which includes glucose oxidase, a peroxidatively-active compound and a chromogen.  Contact of the carrier with a glucose-containing test sample produces a detectable response whereby the glucose concentration can be determined.

Abstract: MECHANISM FOR RAISING AND LOWERING A SEAT, ESPECIALLY  DESIGNED FOR HANDICAPPED PERSONS                      A B S T R A C T     A mechanism for raising and lowering a seat, especially designed for handicapped persons, comprises two supporting arms which are both at one of their ends coupled to the seat, at the front and rear edge thereof respectively.  At their other end, the supporting arms each cooperate with a fixed point.  At least one of the supporting arms is coupled to a driving member and thetwo supporting arms are interconnected at a point between their ends.  With a view to obtaining a space-saving but stable mechanism allowing a physiologically correct trajectory of the seat during its raising and lowering, the supporting arms are directly pivotally interconnected, and one of the supporting arms cooperates with its fixed point in such a manner that it is longitudinally displaceable and rotatable in relation to said point.

Abstract: WIRE ASSEMBLIES FOR REPETITIVE, CONTINUOUS CYCLE, TENSILE        LOAD CONDITIONS, PARTICULARLY SUCKER RODS FOR OIL WELLS            Abstract Multi-wire steel strand for use under repetitive cyclic load conditions, such as in mechanically pumped wells, is provided with end connecting pieces which are swaged into gripping engagement with the strand in a man-ner to avoid fatigue failure of the wire at the end con-nection pieces, by avoiding abrupt load transitions in the wire.  The swaging is such as to gradually and progres-sivlely transfer load from the wire strand to the end con-necting pieces, preferably by virtue of a gradual and pro-gressive increase of the grip between the wire strand and an end piece, considered in the direction of the terminal end of the strand on which the end piece is mounted, in order to gradually reduce the load in the end portion of the strand and avoid abrupt load transitions therein, which can act as stress risers.  A lubricating sleeve insert prevents galling and abrading in the area of rela-tively slight grip where relative movement may occur, 50 as to avoid creating stress risers.  A particular use is for oil well sucker rods, utilizing high carbon, low-relaxation, steel wire, advantageously covered with fiber-glass reinforced plastic while held under tension during curing, although the invention is appropriate for many uses.  The strand diameter will be varied appropriately to suit particular conditions.

Abstract: RESIDUAL MODE PHASE LOCKED LOOP     ABSTRACT      A phase locked loop is disclosed which subtracts an estimated signal from an input signal and operates upon the residual signal.   The residual signal  is demodulated and applied to a controlled oscillator which produces feedback signals approximately the  sine  and  cosine of the  input signal.  The cosine feedback signal is multiplied by the residual  signal  whose  resultant  signal  is  a  frequency correction signal. The sine feedback signal is multiplied by the residual signal for multiplication again by the sine feedback signal to produce the estimated signal which is amplitude and frequency controlled.   This signal is then subtracted from the input signal to reduce the residual signal to near zero.

Abstract: Dispenser for air treating material Abstract The present invention provides a dispenser for an air treating material from which vapours are released into the ambient air through an annular aperture from a round dished base, said dispenser comprising a round dished cover made of an elastic material the top of which curves concavely inwards by exerting pressure on its centre, thereby simultaneously exposing the annular aperture, and  which curves convexly outwards by exerting pressure on the periphery, thereby closing the annular aperture again. The dished cover is provided with a spindle in the centre of the inner wall thereof, which spindle traverses a bracket which is made of elastic material and which is secured to two adjacent positions of the dished base, there being present beneath said bracket a pad of absorbent material containing in the interior thereof a plastic sachet which is imperme-able to liquid and which contains a volatile active product in liquid form. For first time use of the dispenser, pressure is exerted on the centre of the cover so that the spindle is pushed downwards and its tip penetrates the pad beneath the elastic bracket. The plastic sachet in the pad is pierced and the active liquid product is absorbed by the pad.

Abstract: Abstract of the Disclosure An improved apparatus for cutting hair includes a pair of panels which are pivotally interconnected for movement between an open position in which the panels are spaced apart from each other and a closed position in which major sides of the panels are disposed in a side-by-side relationship.  Each of the panels has a nonlinear pattern edge portion which is used to guide a haircutting device, such as scissors or a razor, along a nonlinear path.  The pattern edge portions of the two panels have the same configuration with crests projecting outwardly away from base edge portions of the panels and troughs between the crests.  In order to comb the hair and retain it against sidewise movement along the pattern edge portions, a large number of bristles extend outwardly from a major side of one of the panels.  The hair is laid across the bristles when the panels are in the open position.  The other panel is then clamped against the bristles to hold the hair.
