Abstract: A helmet with an adjustable safety strap. The length of the strap used for securing the helmet can be adjusted by the wearer continuously, or progressively in stages of 1.5 mm, and fixed or released in any of the positions with only one hand, by way of a turn-lock fastener. The turn-lock fastener is rigidly incorporated in the helmet material and has cords which are guided from its two opposite sides along an inner side of the helmet to deflecting rollers, or deflecting points, on the helmet material, and then further guided therefrom along the strap to be tightened. The safety strap can be worn around the nape of the neck, or include a chin piece, among other manners of construction.

Abstract: The WC cleaner has a wipe (3) which takes the form of a disposable wipe which is detachably retained on handle (1), off which it can be pushed. To this end the handle (1) has an internal push-rod (14) which is disposed displaceably in a continuous longitudinal bore in handle (1). After using the WC cleaner, the wipe (3) can be pushed off by pushing the push-rod (14) inside handle (1) down so that it pushes the wipe (3) out of the device holding it on the handle. The disposable wipe (3) is flushed through the WC into the drainage system in the same way as WC paper. The storage device (7) for the disposable wipes (3) consists of a container (8) which is open at the top and has a weighted base (9). The disposable wipes (3) are stored stacked inside the container (8).

Abstract: A resilient element connects the housing of the spindle collar bearing with the spindle rail and contains a circumferential arrangement of resiliently flexible rods surrounding with play the housing of the spindle collar bearing in a substantially parallel relationship thereto. The resiliently flexible rods which are arranged at substantially uniform circumferential spacing from one another extend at both of their ends from an associated common retaining sleeve for the related rod ends. One such retaining sleeve is anchored at the spindle rail. The other retaining sleeve is fixedly anchored at the housing of the spindle collar bearing in a region or at a location spaced from a housing side at which the spindle exits from such housing. The resilient element forms a spatial parallelogram permitting only radial movement of the housing against the spring action of the resiliently flexible rods without inclined positioning of the housing.

Abstract: In a cylinder formed in a casing a hammer piston is mounted for reciprocating motion and is subjected to periodic pressure pulses from a pressure fluid. To prevent a reaction emanating from each pressure pulse from also acting as a shock on the casing, a balance or compensation mass body is provided in the casing which mass body is subjected to the pressure pulses in the direction opposite to that for the hammer piston and is displaceable parallel to the latter against the action of a spring supported in the casing. Together with the spring, the mass body forms an oscillator, the characteristic frequency of which is advantageously to be selected to be at most half, but preferably one third, of the frequency of the pressure pulses. In this way, the reaction shocks are smoothed out to a recoil force which fluctuates narrowly about a mean value and which can be kept lower than the weight of the casing, so that the casing is not subjected to any recoil accelerations.

Abstract: A textile spindle comprising a spindle shaft mounted in an overhung position in a spindle housing by means of two bearings arranged in spaced relationship from one another, the spindle shaft carrying at its free end a whirl and a yarn bobbin. The spindle shaft is supported at the spindle housing between the bearings at the region of its maximum bending- or transverse oscillation deflection via a dampening mechanism.

Abstract: A spinning or plying spindle assembly comprising a spindle shaft rotatably mounted in two bearings mounted in a bearing tube arranged in a bearing housing having a rigid portion so that it can be clamped. First resilient means, e.g. circumferential slots in an intermediate tubular member, in the bearing housing, or a helical slot in the bearing-tube, to allow wobble of one of the bearings adjacent the drive of the spindle, and second resilient means, e.g. longitudinally-spaced webs in the intermediate member or the bearing housing to allow lateral displacement of the bearing adjacent the drive of the spindle in a direction perpendicularly to the axis of the rigid portion of the bearing housing.

Abstract: A textile spindle comprising a spindle housing supporting a collar bearing and a footstep bearing through the agency of elastic bearing elements formed of a yieldable or resilient material. The elastic bearing elements support a rigid bearing tube which houses the collar bearing and the footstep bearing.
