Abstract: ABSTRACT          Sitting bathtub constituted by a tub (10) pro-vided with an opening (11) extending almost down to the bottom of the tub and a hatch (15) to close this opening. When closing the bathtub before having a bath the hatch (15) is placed on the inside of the bathtub and the hydrostatic forces of the water forces the hatch against the edges of the opening where a seal is provided on the hatch.  The sides and in particular the side with the opening are in-clined or sloped outwards from the bottom so that the batch with its seal will rest by its own weight against the seal.  In particular seal (16), hatch (15) and the side of the bathtub are so arranged that a good sealing effect is always certain at the bottom of the bathtub when the rising water and the resulting hydrostatic pres-sure enable the sealing effect to climb upwards even on a light and slightly flexible hatch.  This in turn enables the hatch to be very light and easy to handle and it is thus no inconvience to have a loose hatch.  The hatch is suitably transparent or clear.

Abstract: ABSTRACT OF THE DISCLOSURE           Locking pins are usually in the form of so called split pins.  These pins are impaired by the disadvantage that they normally can be used only once and very often do not form a distinct locking position in the axial direction for the shaft locking which the pin is intended to perform.          These disadvantages are eliminated in that the pin is formed from an elastic material, that it in its longitudinal direction has a symmetry plane, the section of which through the pin forms two opposite outlines one of which bends outwardly.  The bent-out outline has a peak height measured from an opposite straight line, which connects two end points of the second outline of the locking pin, which peak height is larger than the diameter of the bore, into which the locking pin is to be inserted.  The wall thickness of the pin is overall less than the diameter of the bore, whereby at least one of said end points are placed on the end portion of a shoulder, which is formed at the end of the pin.

Abstract: ABSTRACT        A line trimmer for cutting vegetation has features to enable automatic advancement of line increments while rotating. The trimmer has a housing with an aperture on its periphery.  A spool coiled with a flexible cutting line is located in the housing.  The free end of the line extends out of the aperture into a cutting plane.  A set of stop members is located in the housing near the centre in a circular array.  A link is carried in the housing radially outward from the stop members. When the link is in contact with one of the members the spool and housing are locked together for rotation.  Increased centrifugal force urges the drive link outwardly, allowing the spool and housing to slip relative to each other to feed out additional line.  Cam members are located on the inner side of the housing outer wall. These cam members stop further slippage by forcing the link back into engagement with the stop members.

Abstract: Abstract:    The invention is based on the discovery that in a solid electrolyte galvanic sensor, e.g. an yttria-stablized zirconia body, it is not necessary, as has hitherto been believed, to eliminate all impurities to achieve the important performance characteristics of rapid response time, reduced susceptibility to aging, and improved reliability.  It has now been found that these improvements can be obtained by reducing only the concentration of iron oxide (and any other variable valence oxides that sometimes occur) in the sample, and that it is unnecessary to lower the concentration of oxides of fixed valence elements, such as silicon, aluminum, magnesium, and the alkali and alkaline earth metals, many of which tend to occur frequently as impurities in ceramic materials.  This inventive selective elimination of only the variable valence oxides saves substantial cost in manufacture without loss of the performance advantages mentioned above.  Indeed, better mechanical properties are often obtained.  In a specific example the invention provides a solid electrolyte in which the concentration of iron oxide, expressed as Fe2O3, and oxides of other variable valence elements, is less than 0.02 percent by weight, while the concentration of fixed valence oxides remains at least 0.5 percent by weight.

Abstract: ABSTRACT      This die-shaped coarse-approach positioning device is particularly suited forthe sample holder of a scanning tunneling microscope or the like. It comprises two blocks (21, 23), one (21) stationary, the other tiltable with respect to thestationary one. The blocks (21, 23) are connected on one side by a spring-like sheet metal (20). The tiltable block (23) can be moved, and with it the sample (33), by turning a screw (28) which presses down onto an elastic pad (30). The tilting of the tiltable block (23) occurs against the effect of the sheet metal (20) until the block (23) touches down onto a wedge (39) insertable in the gap (24) between the blocks (21, 23), and consisting of an elastic material, however having a spring constant much higher than the effective spring constant of the sheet metal (20). In the application shown, the sample can be lowered onto a tunnel tip (343 attached to a fine-approach positioning device (35).
