Abstract: A strength machine includes a housing having at least two openable or detachable housing shells, a support structure coupled to the housing, a rotatable flywheel mounted on a shaft supported by the support structure, the flywheel being situated between the two housing shells, the flywheel changing its direction of rotation while in operation, a strap- or belt-shaped flexible pulling element attached to the shaft, a hand grip which forms part of or is attached to the flexible pulling element, and an attachment module coupled to the housing, for securing the strength-training machine to an external support.

Abstract: An improved strength machine is at least partly distinguished by the following features: having a housing (20), a housing frame (141), an inner supporting structure (145) and/or an inner frame (145, 150), having a rotatable flywheel weight (13) mounted in the housing (20), on the housing frame (141), on the inner supporting structure (145) or on the inner frame (145, 150), the flywheel weight is fitted on a shaft (12) or is seated on a shaft (12), having a flexible pulling element (3), the flexible pulling element (3) is attached to the shaft (12) or a reel (95) which is mounted on a freewheel bearing (94), which is pretensioned by means of a spring arrangement (96) in the wind-up direction of the pulling element (3).

Abstract: An omnidirectional antenna to equip a sonar, the antenna centered around a longitudinal axis and comprises an assembly of emission rings stacked along the longitudinal axis, each emission ring formed around the longitudinal axis. The emission rings are assembled in groups of ring, the antenna comprises at least two groups of rings and each group of rings comprises at least two rings, the inter-ring spacings between the rings of one and the same group and the inter-group spacings between two successive groups of rings chosen so as to optimize the emission bandwidth and the sound level.

Abstract: A compact omnidirectional antenna for dipping sonar comprises multiple elementary transmission rings formed around a longitudinal axis of the antenna and multiple hydrophones distributed around the longitudinal axis, the antenna intended to be dipped in water, the hydrophones separate from the elementary transmission rings, the hydrophones and the elementary transmission rings fixed in the antenna. The elementary transmission rings and the hydrophones are interlinked along one and the same height (H) measured along the longitudinal axis.

Abstract: A tube having a cylindrical tube body, an end wall closing off one end of the body, and a dispensing nipple disposed on the end wall coaxially to the axis of the tube body. The end wall has at least one portion weakened by reduced wall thickness or reduced material hardness so that two parts of the end wall may be collapsed onto one another for completely emptying the tube. For emptying a tube, an apparatus is provided which has a trough-shaped casing for accommodating the tube and a squeezing body movable within the casing. The casing surrounds the tube through an angle of more than 180° and has a longitudinal slot for manually moving the squeezing body.

Abstract: The present invention relates to high-frequency antennas with high transmission power. The invention consists in making the backing layer of such an antenna with a heat-conductive foam and enables the transmission power to be appreciably doubled.

Abstract: A pillow suitable for therapeutic purposes comprises an upper surface, shaped overall as a cradling surface which in a first cross-sectional direction B—B forms a trough 13 with lateral marginal bulges 14, 15 and in a second cross-sectional direction A—A, aligned across the first cross-sectional direction B—B forms a flat-convex middle bulge 12. When aligning said first cross-sectional direction B—B to the axis of the body, the pillow is particularly suitable for use when lying on one's side; when aligning the other cross-sectional axis A—A, the pillow is particularly suitable for use when lying on one's back.

Abstract: A process for the preparation of diazo pigment mixtures, which comprises condensing 2 mol of an azocarboxylic acid chloride of formula ##STR1## with 1 mol of a mixture of diamines of formulae ##STR2## at a molar ratio of II:III:IV from 0-30:5-60:40-95,the condensation and isolation of the product obtained being carried out by customary methods.The diazo pigment mixtures so obtained are distinguished by high color strength and chroma.

Abstract: A multiple pole, multiple phase, permanent magnet motor comprising a rotor having a plurality of permanent magnet poles, a stator having a plurality of stator slots and an equal number of stator teeth defined by adjacent stator slots, and a plurality of phase windings disposed on the stator, each phase winding including a plurality of coils having a non-uniform number of turns, such that electromagnetic poles are developed in proximity to the stator, the electromagnetic poles for each phase being distributed symmetrically about the stator, equidistant from one another, and equal in number to the number of permanent magnet rotor poles. The number of turns of each of the plurality of coils of each phase winding is selected in accordance with a predetermined sinusoidal relation.
