The seat can also rotate about its own axis of rotation, whereby an infant who is in the seat can walk around the tray, turn in place and use the tray as an eating or play/activity center.

Abstract: The work table with a carrying structure held above the floor by supporting elements (4, 5) and devices for holding table surfaces and/or add-ons in the form of fixedly or moveably arranged resting surfaces includes a base frame (1) of a pair of longitudinal bearers (2) and a pair of transverse bearers (3), which is designed as a structural unit. The supporting elements are fastened to this structural unit as individual table legs (4) or box member in the form of drawer units (5), attached detachably on the underside of the base frame (1). Some of the ends of the longitudinal and/or transverse bearers of the base frame (1) are designed as coupling or resting regions for attachments or add-ons of the work table.Due to the interchangeability of leaf frames (7, 7") which can be coupled to the base frame (1) and bracket elements, the components of the work table can be used on the modular principle.

Abstract: An underdrain assembly contained within a swimming pool filter has a plurality of laterals, each of which is pivotable between a non-operating position and an operating position. Each of the laterals is threadedly attached to the underdrain assembly so that they can be replaced individually by unscrewing them from the underdrain assembly without removing the underdrain assembly from the filter. The laterals can be locked in their operating positions by either a reversible locking mechanism or an irreversible locking mechanism. With the laterals in their non-operating positions, the underdrain assembly and the laterals can be inserted into the filter as a unit.

Abstract: An illuminated ski pole has a light dispersing shaft and/or a light dispersing fiber optic element affixed to its shaft. The light dispersing shaft and the light dispersing fiber optic element have external surfaces which are modified by, for example, roughening, micro-faceting, micro-ridging or micro-grooving so as to enhance the dispersion of light from the shaft and/or the fiber optic element, whereby substantially the entire ski pole can be illuminated.

Abstract: In a clock, a device for planning the sex of a child according to the time selection method exhibits differently marked display sections (3, 4 and 5), relative to a display starting position (2), for labeling the days of fertility and the days of infertility in a cycle and a limited cycle variation range. Within the display section for the days of fertility (4), clearly distinguishably marked day position fields (G and B) are provided which, for cycle lengths of 27 to 30 days, serve as an indication of the days of probability for conceiving a boy or a girl. The counting and display of the days of probability by the cycle pointer (1) occurs from the respective first day of a new menstruation. Correspondingly, the display element (1, 11) can be adjusted to the starting position (2).

A transaction data processing arrangement includes a data input arrangement by which the displayed image identifier is automatically input from the input arrangement. Composite images can be handled.

Abstract: Goods presentation system having slide devices which are displaceable in a longitudinal direction in a C-section rail (1, 1.1) and which can be engaged on predetermined support points (10), for the mounting of support devices to accommodate goods. These slide devices are designed as control locks (3) which can be pushed into the internal space of the section from the front through the section opening and which contain locking jaws (9) which are mounted transversely displaceably in a lock housing (8). The locking jaws (9) can optionally be displaced from an extended locking position, in which they project beyond the lateral walls (8.1) of the housing and in conjunction with the support points (10) establish engagement points for the support devices, into a running position, in which the lock housing (8) is freely displaceable in the C-rail (1, 1.1).The control lock is provided with a cover plate, the front surface (11) of which is intended to receive the support devices.

Abstract: The foot bearing the seat surface of a seat is divided at a distance of 20-30 cm from the seat surface. Between the mutually facing end faces of the two foot parts (5a,5b) a rubber cushion (9) is arranged, the circumferential area of which is widened to form a brake ring (11). The elastic restoring force, working counter to the inclination of the seat, of this cushion is reinforced by two further cushions (16,17) arranged within the foot parts (5a,5b). By means of the suitable arrangement of sliding elements with low friction (T1-T3), the mutual rotation between the two foot parts (5a,5b) is ensured.Thanks to this construction, the seat surface can be swiveled in a tumbling manner in such a way that every point of said seat surface moves on an imaginary spherical surface and thanks to the mentioned elastic restoring force, the seat part always returns automatically to its initial position.

Abstract: Fastening element (5) secured against rotation for a structural part (4) to be removably attached to a supporting arrangement (1), which has a screw bolt (7) and a locking nut (10) to be tightened on the front side of the structural part (4). The screw bolt (7) is situated rotatably and longitudinally movably in an adaptor sleeve (6) which has a shaft part (6.1), which engages with little play in corresponding openings of the supporting arrangement (1) and of the structural part (4). The screw bolt (7) has at its inner end a hammer head (8), the cross-sectional shape of which is adjusted to that of the shaft part (6.1) of the adaptor sleeve (6) and which can be brought from an insertion position into a locking position swivelled through approximately 90.degree. to it. The structural part to be attached to the supporting arrangement (1) is forcibly held in position by means of penetration openings of equal area which are matched to the cross-sectional shape of the shaft part (6.1) of the adaptor sleeve (6).

Abstract: A stirring mechanism, with a plurality of hollow, at least partially conically shaped stirring elements, which are provided with two openings, are symmetrically offset and are fixed on the stirring shaft (2) at least approximately tangential to an imaginary circular cylinder coaxial to the stirring shaft.In the starting phase, the stirred substance flows laminarly through the stirring elements 8. However, as soon as they have reached a predetermined minimum velocity of about 1.3 m/s, the flow inside the stirring elements 8 is forced to reverse by dynamic pressure. The resultant counterflow (11, 12, 13) brings about an outstanding, extensive and nevertheless extremely gentle stirring effect with low power consumption. Also, an effective and uniform gassing can be obtained with simple means, without the stirring velocity having to be increased.
