Abstract: A mop and mop-squeeze combination has a handle (1), a mop head (4) and a wringer device (3) disposed behind the mop head (4), the wringer device comprising a box-like sheath (14), a squeeze roller (23) supported in oblique guides (22) and traveling from the outside inward, and opposed guide rollers (20). The wet mop cloth is wrung out by being pulled into the sheath.

Abstract: A kitchen appliance for cutting fruit and vegetables in slices, with an upper rigid guide plate (2) carrying a cutting knife (5) extending at an acute angle (4) to the side wall, and with a lower tongue-like guide plate (3) which is adjusted vertically by an adjusting rod (20) guided in the frame (1) and extending approximately parallel to the cutting knife (5), and which is connected to the frame (1) via a film hinge (13).

Abstract: A cleaning brush for brushing clothing has a slip case that circumferentially surrounds a passage having a brush therein. The slip case has open ends, the brush being slid into and out of the slip case through either end. The slip case acts as a handle.

Abstract: Keep-fresh storage container having a two-part lid consisting of a stiff part with handle webs and rim and of a deformable sealing part fastened thereto.

Abstract: A device for atomizing a sample for so-called flameless atomic absorption spectroscopic measurements of the type in which an electrically conducting hollow tube, into which the sample is introduced as by a central port in the side of the tube, is heated by the passage of current from electrodes contacting the ends of the tube. A protective inert gas is caused to surround the interior and exterior of the tube to exclude air to avoid oxidation of the sample tube which may be graphite. The improvement comprises introducing the protective gas into both ends of the sample tube so that it leaves the interior through the central port from which it may be sucked outside of a surrounding housing. The exterior walls of the sample tube may be provided with protective gas either by means of an auxiliary gas flow or by leading the gas from the bore around the outside of the tube before withdrawing it through the surrounding housing.
