Abstract: A winch operated by a manual crank and handle for reeling-up or out a belt or rope and including a holding catch for preventing reeling-out when the handle is not actuated. A friction coupling mechanism is momentarily released when the handle is moved in the reeling-out direction, resulting in that the load is moved downwardly and actuates a screw mechanism which momentarily locks the coupling if the handle is stopped. Reeling-out is thus effected by releasing and locking actions following each other at very small intervals, the reeling-out movement being practically synchronous with the movement of the handle until it is stopped.

Abstract: A patient lift and transport apparatus with means for lifting a patient from a sitting position on a chair or bed to a transporting position in the apparatus. The apparatus is provided with retaining means for holding the patient in a sitting position during transportation, with the knees resting against a knee support and the seat of the patient resting against a lifting belt extending obliquely upwards over the region of the neck of the patient's femurs, said lifting belt being removably secured to two fastenings on the apparatus.

Abstract: A prosthesis for an amputated lower leg consisting of an upper part attachable to the remaining lower leg stump, this upper part being attached to an under part provided with an artificial foot. The upper part has a cup-shaped bottom portion which at a number of places along its circumference merges into upwardly directed flexible strips of such lengths that when the leg stump is placed between them they extend up along the leg stump and thigh, the bottom portion and strips forming a holder fitting, with an approximately predetermined and relatively large play, around the bandaged leg stump itself so that this play can be filled with a supporting structure around the leg stump.

Abstract: A protective glove consists of two plastic films such as polyethylene welded at the periphery of the glove, whereat at least one of the films has protuberances on one side. At least one film having a thickness in the region of 0.01 to 1.0 mm is made with commonly separated impressions on one side for providing corresponding protuberances on its other side. Said protuberances are substantially evenly distributed over the entire surface of the film and lie at such a small distance from each other, preferably in the region of 0.5 to 2 mm, that the adhesion between the films is at least partially inhibited to facilitate the introduction of a hand into the glove.

Abstract: A chair, particularly a wheel-chair, having a spring biased tiltable back-rest and two pivotal leg supports including each a foot rest. The length of the leg supports from their pivot axis is automatically extended when the leg supports are swung to their horizontal position. The leg supports are provided with simple adjusting means to enable continuous adjustment of the length of the leg supports and with simple releasable means to lock and release the leg supports respectively in any angular or horizontal position.

Abstract: A wheel-chair having a spring biased tiltable back-rest. The resilient force exerted on the back-rest by the spring is continuously adjustable to suit the actual person sitting in the chair. Preferably, the spring is a gas spring which is combined with a device reducing the effect of the gas spring when the back-rest is in its upright position and adds to its effect when the back-rest is adjacent or in its horizontal position.
