A mounting for poles of jumps in equestrian sport. A dish-shaped pole receiver suspended on a generally vertical rail can be connected together by bolts, then fixed to a stand. The bolts, which are flanged such that the shaft is not as wide as the head, extend in multi-segmented slots having serially connected narrow, wide and further narrow portions. The width of the narrow portion of the slot corresponds to approximately the width of the bolt shaft, while the wide portion of the slot is wide enough to accommodate the bolt head. The slot can secure the bolts by firstly introducing the bolt head into the wide portion of the slot, then engaging the shaft with the narrow part of the slot until the shaft comes in contact with the further narrow portion. The further narrow portion, on which the shaft rests, gives way under a pre-determined vertical loading, so that the pole and pole receiver are forced downwards when this loading is exceeded, causing the shaft to deform the further narrow portion as it passes through.

Mounting for jumps

A mounting for poles of jumps in equestrian sport, with a dish-shaped pole receiver which is suspended on a generally vertical rail adapted to be fixed to a stand. The pole receiver and the rail can be connected together by bolts which extend in one or more multi-segmented slots having one or more serially connected narrow, wide and further narrow portions. The bolts are flanged, or headed such that the shaft is not as wide as the head. The width of the narrow portion of the slot corresponds to approximately the width of the bolt shaft, while the wide portion of the slot is wide enough to accommodate the bolt head. The slot is able to secure the bolts by firstly introducing the bolt head into the wide portion of the slot, then engaging the shaft with the narrow part of the slot until the shaft comes in contact with the further narrow portion. The further narrow portion, on which the shaft rests, gives way under a pre-determined and relatively low vertical loading, so that the pole and pole receiver are forced downwards when this loading is exceeded, causing the shaft to deform the further narrow portion as it passes through. Consequent disengagement of the pole and pole receiver from the stand reduces the risk of injury to a horse and its rider, as well as destruction or damage to the pole mounting.

A method for setting the ends of bundles of hollow fibers in an end wall contained within a housing are disclosed, including providing a bundle of hollow fibers having adjacent open end faces, supplying a hardenable liquid material to those end faces so that this material can penetrate between the hollow fibers and into the interiors thereof, and exerting a positive pressure within the housing containing the hollow fibers to control the degree of penetration of the hardenable liquid material both between and within the interior of the hollow fibers.

Method for setting the ends of hollow fiber bundles

Method of treating a cellulosic hollow fiber which is being particularly adapted for use in hemodialysis or a similar extracorporeal treatment of blood. According to the described method the hollow fiber, possibly after rinsing with an alcoholic solution or fluorinated hydrocarbons, is exposed to swelling with use of an aqueous solution prior to drying and/sterilization of the hollow fiber. Examples of aqueous solutions can be water, water/glycerol, and water/glycerol/alcohol. Preferably said aqueous solution contains glycerol in an amount of 4-35%, such as 12-35%, preferably 16-35%. The aqueous solution can be applied to the inside and/or the outside of the hollow fiber so as to bring about a diffusive and/or a convective transport of water and/or glycerol into the hollow fiber wall. The rate of diffusion can be increased by increasing the temperature of the aqueous solution, by increasing the contact time between the aqueous solution and the hollow fiber, or by increasing the glycerol content of the aqueous solution, and the convective transport of said substances is achieved by applying the aqueous solution under pressure. After drying, the hollow fiber can be sterilized either by temperature or by radiation without any substantial loss of permeability characteristics.
