Abstract: ABSTRACT   A stair climbing wheelchair carrier, comprising a carrier portion comprising a pair of endless belt crawlers, and a handle portion rotatably and detachably provided on the carrier.  The handle portion is adapted to be rotated between an operating position and a wheelchair engaging position. The endless belt crawler has an oblique overhang portion which has a height higher than a usual height of a step of stair.  The upper travelling portion of endless belt crawlers are maintained by idlers in substantially horizontal position except the oblique overhang portion so that the wheelchair may be moved on the carrier portion and may be engaged with the handle portion at the wheelchair engaging position of the handle portion.  The wheelchair is mounted on the carrier portion by rotating the handle portion to the operating position.

Abstract: PHN . 9838                     13 ABSTRACT:         The invention relates to a high-pressure dis-charge lamp having a ceramic discharge vessel comprising an ionizable filling which in the operating condition of the lamp comprises a component present in excess, and in which two electrodes are present.  The electrode is con-nected to a pin-shaped current supply member which is surrounded with a small gap by an end portion of the dis-charge vessel.  According to the invention the pin-shaped current supply member and the end portion are connected in a gas-tight manner by means of a glass seal, in which the sealing glass seal extends into the small gap in the direction towards the electrode over such a distance that, in the operating condition of the lamp, the temperature at the surface of the glass seal facing the discharge is at least 50 K lower than the temperature of that part of the filling which determines the vapour pressure of the com-ponent present in excess.  Herewith a high-pressure dis-charge vessel is obtained in which attack of the glass seal by components of the lamp filling is prevented.

Abstract: Abstract of the Disclosure Surfac? treatment, for example precious metal plating, on preselected areas of elongate three dimensional objects is obtained by applying a masking member, at least to the ends of the objects.  The masking member has a shape such that when the objects are inserted into bores in the member, predetermined areas are exposed where the bores open out through the member.  A typical shape is a dumb-bell shape, with the central web portion of the same dimension as the bores.  Thus the bore  break through.  The objects, for example terminal pins, are mounted on a support strip in spaced array and a plurality of masking members attached prior to passing through treatment tanks, for example plating tanks.
