Abstract: Electrical coupling device with a measuring contact bank fixedly mounted on an appliance frame and a bush contact bank arranged inside a housing, where one of the front ends of the housing can be fixed on the appliance frame while its other front end can be fastened by means of a hook provided on the housing and a corresponding nose on the apparatus frame. In said electrical device, the housing (5) is provided with a frame (9) and modular bush contacts (11) are arranged in the inner part (9') of the housing.

Abstract: A ski pole hand guard is intended to be mounted on a ski pole directly below the hand grip. This hand guard includes a pole attachment member and a cup-shaped, almost semi-circular guard member which surrounds the hand grip in an arc of less than 180.degree. and projects outwardly slightly beyond the normal distance needed to clear a skier's ski glove. A top flange member extends from the top edge of the guard member inwardly towards the center line of the ski pole. The hand guard structure is constructed of durable, impact resistant material and is rigidly attached to the pole attachement member. When in use, the skier grasps the ski pole hand grip as normal and has the first joint of his thumb and the first, second and third joints of his fingers within the bounds of the guard member and flange memner. The hand guard sufficiently surrounds a skier's hand to retain it during the initial fall reflex and protect it from the impact of the initial contact made during a normal fall.

Abstract: A toilet chair comprises a seat portion supported on a support frame. A footrest mounted on the frame is pivotable between an operative forwardly projecting position and a retracted position within the frame, and the frame is open at the rear to fit over and around a WC pan. The frame has a front cross member on which the footrest is pivotally mounted. Projections of the footrest engage the cross member to define the lowered operative position of the footrest and thus the cross member 12 provides stop means defining that position, in addition to being a structural member of the frame and forming a pivot shaft for the footrest.

Abstract: A process of upgrading hydrogen chloride which contains chlorine, iron-III-chloride, acetylene and/or ethylene, for use in an oxichlorination process, wherein water in a gaseous state is added to the hydrogen chloride at temperatures between 120.degree. and 180.degree. C. within a time period of maximally 0.9 seconds after the acetylene and/or ethylene is present in the hydrogen chloride, together with chlorine and iron-III-chloride.
